Details of the business to be conducted at the meeting are given in the Notice of Annual Meeting of Stockholders and Proxy Statement which follow this letter. The 2018 Annual Report to Stockholders is also included with these materials.

We have mailed to many of our stockholders a Notice of Internet Availability of Proxy Materials (the “Notice”) containing instructions on how to access our 2019 Proxy Statement and our 2018 Annual Report to Stockholders, and how to vote online on the three management Proposals put before you this year. The Notice also includes instructions on how to request a paper or email copy of the proxy materials, including the Notice of Annual Meeting, Proxy Statement and Annual Report, and proxy card or voting instruction card. Stockholders who previously either requested paper copies of the proxy materials or elected to receive the proxy materials electronically did not receive a Notice, and will receive the proxy materials in the format requested.

PROXY STATEMENT

For the Annual Meeting of Stockholders to be held on May 30, 2019

GENERAL INFORMATION

The Annual Meeting and Proposals

The 2019 Annual Meeting of Stockholders of Gartner, Inc. will be held on Thursday, May 30, 2019, at 10:00 a.m. local time, for the purposes set forth in the accompanying Notice of Annual Meeting of Stockholders and described in greater detail below. This Proxy Statement and form of proxy, together with our 2018 Annual Report to Stockholders, are being furnished in connection with the solicitation by the Board of Directors of proxies to be used at the meeting and any adjournment of the meeting, and are first being made available to our stockholders on or around April 16, 2019. We will refer to your company in this Proxy Statement as “we”, “us”, the “Company” or “Gartner.” The three proposals to be considered and acted upon at the Annual Meeting, which are described in more detail in this Proxy Statement, are:

Management does not intend to present any other items of business and is not aware of any matters other than those set forth in this Proxy Statement for action at the 2019 Annual Meeting of Stockholders. However, if any other matters properly come before the Annual Meeting, the persons designated by the Company as proxies may vote the shares of Common Stock they represent in their discretion.

Information Concerning Proxy Materials and the Voting of Proxies

Why is it Important to Vote?

Voting your shares is important to ensure that you have a say in the governance of the Company. Additionally, repeated failure to vote may subject your shares to risk of escheatment. Please review the proxy materials and follow the relevant instructions to vote your shares. We hope you will exercise your rights and fully participate as a stockholder in the future of Gartner.

Why Did You Receive a Notice Regarding Availability of Proxy Materials?

The Securities and Exchange Commission (“SEC”) rules allow companies to furnish proxy materials to their stockholders via the Internet. This “e-proxy” process expedites stockholders’ receipt of proxy materials, while significantly lowering the costs and reducing the environmental impact of our annual meeting. Accordingly, on

April 16, 2019, we mailed to our stockholders (other than those who previously have requested printed proxy materials) a Notice of Internet Availability of Proxy Materials (the “Notice”). If you received a Notice, you will not receive a printed copy of the proxy materials unless you request one. The Notice provides instructions on how to access our proxy materials for the Annual Meeting on a website, how to request a printed copy of the proxy materials and how to vote your shares. We will mail printed copies of our proxy materials to those stockholders who have already elected to receive printed proxy materials.

If Your Shares Are Held in “Street Name,” How Are Your Shares Voted?

If you are the beneficial owner of shares (meaning that your shares are held in the name of a bank, brokerage or other nominee; i.e., “street name” accounts), you may receive a Notice of Internet Availability of Proxy Materials from that firm containing instructions you must follow in order for your shares to be voted. Additionally, under applicable New York Stock Exchange (“NYSE”) rules relating to the discretionary voting of proxies, banks, brokers and other nominees are not permitted to vote shares with respect to “non-routine” matters, such as the election of directors and the say on pay proposal presented this year without instructions from the beneficial owner, except they are able to vote without instructions on “routine” matters, such as the ratification of the appointment of an independent registered public accounting firm. Therefore, beneficial holders are advised that, if they do not timely provide instructions to their bank, broker or other nominee, their shares will not be voted in connection with Proposals One and Two, but may be voted in connection with Proposal Three. Generally, broker non-votes occur on a matter when a broker is not permitted to vote on that matter without instructions from the beneficial owner and instructions are not given.

If You Are the Holder of Record of Your Shares, How Are Your Shares Voted?

If you are the holder of record of your shares, you will either receive a Notice or printed proxy materials if you have already elected to receive printed materials. The Notice will contain instructions you must follow to vote your shares. If you received proxy materials in paper form, the materials include a proxy card instructing the holder of record how to vote the shares.

How Can You Get Electronic Access to Proxy Materials?

The Notice provides instructions regarding how to view our proxy materials for the Annual Meeting online. Additionally, materials are available on www.proxyvote.com and have available your 12-digit Control number(s) located on your Notice.

How Can You Request Paper or Email Copies of Proxy Materials?

If you received a Notice by mail, you will not receive a printed copy of the proxy materials. If you want to receive paper or email copies of the proxy materials, you must request them. There is no charge for requesting a copy. To facilitate timely delivery, please make your request on or before May 15, 2019. To request paper or email copies, stockholders can go to www.proxyvote.com, call 1-800-579-1639 or send an email to sendmaterial@proxyvote.com. Please note that if you request materials by email, send a blank email with your 12-digit Control number(s) (located on your Notice) in the subject line.

How Can You Sign Up to Receive Future Proxy Materials Electronically?

You have the option to receive all future proxy statements, proxy cards and annual reports electronically via email or the Internet. If you elect this option, the Company will only mail printed materials to you in the future if you request that we do so. To sign up for electronic delivery, please follow the instructions below under How Can You Vote to vote using the Internet and vote your shares. After submitting your vote, follow the prompts to sign up for electronic delivery.

What is “Householding”?

We have adopted “householding” procedures that allow us to deliver proxy materials more cost-effectively. If you are a beneficial owner of shares and you and other residents at your mailing address share the same last name and also own shares of common stock in an account at the same bank, brokerage, or other nominee, your

nominee delivered a single Notice or set of proxy materials to your address. This method of delivery is known as householding. Householding reduces the number of mailings you receive, saves on printing and postage costs and helps the environment. Stockholders participating in householding continue to receive separate proxy cards and control numbers for voting electronically.

We will deliver promptly a separate copy of the Notice or proxy materials to a stockholder at a shared address to which a single copy was delivered. A stockholder who received a single Notice or set of proxy materials to a shared address may request a separate copy of the Notice or proxy materials be sent to him or her by contacting in writing Broadridge Financial Solutions, Inc. (“Broadridge”), Householding Department at 51 Mercedes Way, Edgewood, New York, 11717, or calling 1-800-542-1061. If you would like to opt out of householding for future deliveries of proxy materials, please contact your broker, bank or other nominee.

Beneficial owners of shares who share an address and receive multiple copies of the proxy materials but want to receive only a single copy of these materials in the future should contact their bank, brokerage or other nominee and make this request.

Who Can Vote at the Annual Meeting?

Only stockholders of record at the close of business on April 5, 2019 (the “Record Date”) may vote at the Annual Meeting. As of the Record Date, there were 89,948,555 shares of our common stock, par value $.0005 per share (“Common Stock”) outstanding and eligible to be voted. This amount does not include treasury shares which are not voted.

How Can You Vote?

You may vote using one of the following methods:

All shares that have been voted properly by an unrevoked proxy will be voted at the Annual Meeting in accordance with your instructions. If you sign and submit your proxy card, but do not give voting instructions, the shares represented by that proxy will be voted for each proposal as our Board recommends.

How to Revoke Your Proxy or Change Your Vote

A later vote by any means will cancel an earlier vote. You can revoke your proxy or change your vote before your proxy is voted at the Annual Meeting by giving written notice of revocation to: Corporate Secretary, Gartner, Inc., 56 Top Gallant Road, P.O. Box 10212, Stamford, Connecticut 06904-2212; or submitting another timely proxy by the Internet, telephone or mail; or attending the Annual Meeting to vote in person. If your shares are held in the name of a bank, broker or other holder of record, to vote at the Annual Meeting you must obtain a proxy executed in your favor from your bank, broker or other holder of record and bring it to the Annual Meeting in order to vote. Attendance at the Annual Meeting will not, by itself, revoke your prior proxy.

How Many Votes You Have

Each stockholder has one vote for each share of our Common Stock owned on the Record Date for all matters being voted on.

Quorum

A quorum is constituted by the presence, in person or by proxy, of holders of our Common Stock representing a majority of the number of shares of Common Stock entitled to vote. Abstentions and broker non-votes (described above) will be considered present to determine a quorum.

Votes Required

Proposal One: Each nominee must receive more “FOR” votes than “AGAINST” votes to be elected. Abstentions and broker non-votes will have no effect on the outcome of the election. Any nominee who fails to achieve this threshold must tender his or her resignation from the Board pursuant to the Company’s majority vote standard.

Proposals Two and Three: The affirmative “FOR” vote of a majority of the votes of shares of Common Stock present in person or represented by proxy is required to approve Proposal Two - the advisory (non-binding) approval of the Company’s executive compensation; and Proposal Three - the ratification of the appointment of KPMG LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2019. For Proposals Two and Three, abstentions have the same effect as “AGAINST” votes. Broker non-votes, if any, will have no effect on the outcome of these matters.

If any other matters are brought properly before the Annual Meeting, the persons named as proxies in the accompanying proxy card will have the discretion to vote on those matters for you. If for any reason any of the nominees is not available as a candidate for director at the Annual Meeting, the persons named as proxies will vote your proxy for such other candidate or candidates as may be nominated by the Board of Directors. As of the date of this Proxy Statement, we were unaware of any other matter to be raised at the Annual Meeting.

What Are the Recommendations of the Board?

The Board of Directors recommends that you vote:

Who Is Distributing Proxy Materials and Bearing the Cost of the Solicitation?

This solicitation of proxies is being made by the Board of Directors and we will bear the entire cost of this solicitation, including costs associated with mailing the Notice and related Internet access to proxy materials, the preparation, assembly, printing, and mailing of this Proxy Statement, the proxy card, and any additional

solicitation material that we may provide to stockholders. Gartner will request brokerage firms, fiduciaries and custodians holding shares in their names that are beneficially owned by others to solicit proxies from these persons and will pay the costs associated with such activities. The original solicitation of proxies may be supplemented by solicitation by telephone, electronic mail and other means by our directors, officers and employees. No additional compensation will be paid to these individuals for any such services. We have also retained Georgeson LLC to assist with the solicitation of proxies at an anticipated cost of $7,000, which will be paid by the Company.

Where can I find the voting results of the Annual Meeting?

We will disclose voting results on a Form 8-K that will be filed with the SEC within four business days after the Annual Meeting, which will also be available on our investor relations website – https://investor.gartner.com.

THE BOARD OF DIRECTORS

General Information about our Board of Directors

Our Board currently has ten directors who serve for annual terms. Our CEO, Eugene A. Hall, has an employment agreement with the Company that obligates the Company to include him on the slate of nominees to be elected to our Board during the term of the agreement. See Executive Compensation – Employment Agreements with Executive Officers below. There are no other arrangements between any director or nominee and any other person pursuant to which the director or nominee was selected. None of our directors or executive officers is related to another director or executive officer by blood, marriage or adoption.

Each member of our Board has been nominated for re-election at the 2019 Annual Meeting. See Proposal One – Election of Directors on page 18. Set forth below are the name, age, principal occupation for the last five years, public company board experience, selected additional biographical information and period of service as a director of the Company of each director, as well as a summary of each director’s experience, qualifications and background which, among other factors, support their respective qualifications to continue to serve on our Board.

Majority Vote Standard

The Company has adopted a majority vote standard for the election of directors which provides that a nominee must receive more FOR votes than AGAINST votes for election as a director. Should a nominee fail to achieve this threshold, the nominee must immediately tender his or her resignation to the Chairman. The Board, in its discretion, can determine whether or not to accept the resignation.

Compensation of Directors

The Compensation Committee, in consultation with the Governance Committee, reviews all forms of independent director compensation and approves changes, when appropriate. The Compensation and Governance Committees are supported in this review by Exequity, LLP. The review examines director compensation in relation to two comparator groups: Peer Group and General Industry Reference Group. The Peer Group includes the same companies used to benchmark executive pay. The General Industry Reference Group includes 100 companies with median revenues similar to that of Gartner. Regular review of the director compensation program ensures that the director compensation is reasonable, and reflects a mainstream approach to the structure of the compensation components and the method of delivery. Director compensation is primarily reviewed in relation to the Peer Group. Gartner adjusted director compensation in 2018 to close an identified shortfall from the Peer Group median, increasing the director annual equity grant from $200,000 to $240,000. An increase in equity compensation was the only change made to director compensation in following with Gartner’s philosophy to provide more value in equity compensation than cash. The section that follows describes the current director compensation program and components.

Directors who are also employees receive no fees for their services as directors. Non-management directors are reimbursed for their meeting attendance expenses and receive the following compensation for their service as director:

Director Compensation Table

This table sets forth compensation earned or paid in cash, and the grant date fair value of equity awards made, to our non-management directors on account of services rendered as a director in 2018. Mr. Hall receives no additional compensation for service as director.

*Mr. Bingle resigned from the Board and the Compensation Committee effective July 26, 2018.

Director Stock Ownership and Holding Period Guidelines

The Board believes directors should have a financial interest in the Company. Accordingly, each director is required to hold shares of Gartner common stock with a value of not less than five (5) times the Annual Director Retainer Fee ($60,000). Directors are required to achieve the guideline within three years of joining the Board. In the event a director has not satisfied the guideline within such three year period, he/she will be required to hold 50% of net after-tax shares received from the Company either in the form of equity awards or released CSEs until the guideline is achieved. We permit directors to apply deferred and unvested equity awards towards satisfying these requirements. As of December 31, 2018, all of our directors were in compliance with these guidelines.

CORPORATE GOVERNANCE

Gartner is committed to maintaining strong corporate governance practices.

Board Principles and Practices

Our Board Principles and Practices (the “Board Guidelines”) are reviewed annually and revised in light of legal, regulatory or other developments, as well as emerging best practices, by our Governance Committee and Board. The Board Guidelines, which are posted on https://investor.gartner.com, describe the Board’s responsibilities, its role in strategic development and other matters, discussed below.

Director Independence

Our Board Guidelines require that our Board be comprised of a majority of directors who meet the criteria for independence from management set forth by the NYSE in its corporate governance listing standards.

Our committee charters likewise require that our standing Audit, Compensation and Governance/Nominating Committees be comprised only of independent directors. Additionally, the Audit Committee members must be independent under Section 10A-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Compensation Committee members must be independent under Rule 16b-3 promulgated under the Exchange Act as well as applicable NYSE corporate governance listing standards, and they must qualify as outside directors under regulations promulgated under Section 162(m) (“Section 162(m)”) of the Internal Revenue Code of 1986, as amended (the “Code”).

Utilizing all of these criteria, as well as all relevant facts and circumstances, the Board annually assesses the independence from management of all non-management directors and committee members by reviewing the commercial, financial, familial, employment and other relationships between each director and the Company, its auditors and other companies that do business with Gartner. Because of our worldwide reach, it is not unusual for Gartner to engage in ordinary course of business transactions involving the sale of research or consulting services with entities affiliated with one of our directors, or their immediate family members. The Board considered these transactions in determining director independence.

After analysis and recommendation by the Governance Committee, the Board determined that:

Board Leadership Structure

The leadership of our Board of Directors rests with our independent Chairman of the Board, Mr. James C. Smith. Gartner believes that the separation of functions between the CEO and Chairman of the Board provides independent leadership of the Board in the exercise of its management oversight responsibilities, increases the accountability of the CEO and creates transparency into the relationship among executive management, the Board of Directors and the stockholders. Additionally, in view of Mr. Smith’s extensive experience as a chief executive officer of a major corporation, he is able to provide an independent point of view to our CEO on important management and operational issues.

Risk Oversight

The Board of Directors, together with management, oversees risk (including cybersecurity risk) at Gartner. The Company’s strategic objectives and activities are presented by executive management to the Board and approved annually and more frequently as necessary. The Board regularly receives updates on cybersecurity matters from the Company’s Chief Information Officer and discusses issues identified at its meetings.

The Risk (Internal Audit) function reports directly to the Audit Committee, and provides quarterly reports to the committee. The committee reviews the results of the internal audit annual risk assessment and the proposed internal audit plan. Subsequent quarterly meetings include an update on ongoing internal audit activities, including results of audits and any changes to the audit plan. Risk also meets with the Audit Committee in executive session on a quarterly basis.

The General Counsel, who serves as Chief Compliance Officer, also reports directly to the Audit Committee on a quarterly basis concerning the effectiveness and status of the Company’s legal and ethical compliance program and initiatives, hotline activities and litigation matters.

The Company maintains internal controls and procedures over financial reporting, as well as enterprise wide internal controls, which are updated and tested annually by management and our independent registered public accounting firm. Any internal control deficiencies and the status of remediation efforts as well as any findings of the Disclosure Controls Committee are reported to the Audit Committee on a quarterly basis.

Risk Assessment of Compensation Policies and Practices

Management conducts an annual risk assessment of the Company’s compensation policies and practices, including all executive, non-executive and business unit compensation policies and practices, as well as the variable compensation policies applicable to our global sales force. The results of this assessment are reported to the Compensation Committee. For 2018, management concluded, and the Compensation Committee agreed, that no Company compensation policies and practices created risks that were reasonably likely to have a material adverse effect on the Company.

Management Succession Planning

Succession planning is one of the Board’s most critical functions—to develop leaders who will successfully build the Company’s business. The Board and its Committees regularly review and discuss management development and succession plans for the Chief Executive Officer and his direct reports. This review includes an assessment of senior executives and their potential as successor to the Chief Executive Officer.

Board and Committee Meetings and Annual Meeting Attendance

Our Board held four meetings in 2018. During 2018, all of our directors attended at least 75% of the Board and committee meetings held during the periods in which such director served as a director and/or committee member. At each regular quarterly Board and committee meeting, time is set aside for the non-management directors to meet in executive session without management present. James C. Smith, our non-executive Chairman of the Board, presides over the executive sessions at the Board meetings, and each committee chairperson presides over the executive sessions at their respective committee meetings. Directors are not required, but are invited, to attend the Annual Meeting of Stockholders. In 2018, Mr. Hall and other executive officers of the Company attended the 2018 Annual Meeting of Stockholders.

Committees Generally and Charters

As noted above, our Board has three standing committees: Audit, Compensation and Governance/Nominating, and all committee members have been determined by our Board to be independent under applicable standards. Our Board of Directors has approved a written charter for each standing committee, which is reviewed annually and revised as appropriate. The table below provides information for each Board committee in 2018:

* Mr. Bingle, resigned from the Board and the Compensation Committee effective July 26, 2018.

Audit Committee

Gartner has a separately designated standing audit committee established in accordance with Section 3(a)(58)(A) of the Exchange Act. Our Board has determined that both Ms. Dykstra and Mr. Bressler qualify as audit

committee financial experts, as defined by the rules of the SEC, and that all members have the requisite accounting or related financial management expertise and are financially literate as required by the NYSE corporate governance listing standards.

Additionally, the Audit Committee is directly responsible for the appointment, compensation and oversight of our independent registered public accounting firm, KPMG; approves the engagement letter describing the scope of the annual audit; approves fees for audit and non-audit services; provides an open avenue of communication among the independent registered public accounting firm, the Risk and Internal Audit functions, management and the Board; resolves disagreements, if any, between management and the independent registered public accounting firm regarding financial reporting for the purpose of issuing an audit report in connection with our financial statements and our internal control over financial reporting; and prepares the Audit Committee Report required by the SEC and included in this Proxy Statement on page 54 below.

The independent registered public accounting firm reports directly to the Audit Committee. By meeting with the independent registered public accounting firm and the internal auditor, and operating and financial management personnel, the Audit Committee oversees matters relating to accounting standards, policies and practices, any changes thereto and the effects of any changes on our financial statements, financial reporting practices and the quality and adequacy of internal controls. Additionally, our internal audit and compliance functions report directly to the Audit Committee. After each Audit Committee meeting, the Committee meets separately with the CFO, the independent registered public accounting firm and the internal auditor without management present.

The Audit Committee has established procedures for (i) the receipt, retention and treatment of complaints received by the Company regarding accounting, internal accounting controls or auditing matters, and (ii) the confidential, anonymous submission by employees of concerns regarding questionable accounting or auditing matters. A toll-free phone number managed by a third party is available for confidential and anonymous submission of concerns relating to accounting, auditing and other illegal or unethical matters, as well as alleged violations of Gartner’s Code of Conduct or any other policies. All submissions on the hotline are reported to the General Counsel, who determines the mode of investigation, to the internal auditor and to the Audit Committee at each regular meeting. The Audit Committee has the power and funding to retain independent counsel and other advisors as it deems necessary to carry out its duties.

Compensation Committee

The Compensation Committee reviewed and approved the Compensation Discussion and Analysis contained in this Proxy Statement, recommended its inclusion herein (and in our 2018 Annual Report on Form 10-K) and issued the related report to stockholders as required by the SEC (see Compensation Committee Report on page 35 below).

Exequity LLP (“Exequity”) was retained by the Compensation Committee to provide information, analyses, and advice to the Committee during various stages of 2018 executive compensation planning. Exequity reports directly to the Compensation Committee chair. In the course of conducting its activities, Exequity attended meetings of the Compensation Committee and briefed the Committee on executive compensation trends generally.

The Compensation Committee has assessed the independence of Exequity, and has concluded that Exequity is independent and that its retention presents no conflicts of interest either to the Committee or the Company.

Final decisions with respect to determining the amount or form of executive compensation under the Company’s executive compensation programs are made by the Compensation Committee alone and may reflect factors and considerations other than the information and advice provided by its consultants. Please refer to the Compensation Discussion & Analysis beginning on page 21 for a more detailed discussion of the Compensation Committee’s activities with respect to executive compensation.

Compensation Committee Interlocks and Insider Participation. During 2018, no member of the Compensation Committee served as an officer or employee of the Company, was formerly an officer of the Company or had any relationship with the Company required to be disclosed under Transactions With Related Persons below. Additionally, during 2018, no executive officer of the Company: (i) served as a member of the compensation committee (or full board in the absence of such a committee) or as a director of another entity, one of whose executive officers served on our Compensation Committee; or (ii) served as a member of the compensation committee (or full board in the absence of such a committee) of another entity, one of whose executive officers served on our Board.

Governance/Nominating Committee

While the Governance Committee has not specified minimum qualifications for candidates it recommends, it will consider the qualifications, skills, expertise, qualities, diversity, age, gender, availability and experience of all candidates that are presented for consideration. At the present time, three of our ten directors are women. The Board utilizes a concept of diversity that extends beyond race, gender and national origin to encompass the viewpoints, professional experience and other individual qualities and attributes of candidates that will enable the

Board to select candidates who are best able to carry out the Board’s responsibilities and complement the mix of talent and experience represented on the Board. In connection with its annual evaluation, the Board considers the appropriateness of the qualifications of existing directors given then current needs.

Candidates for Board nomination may be brought to the attention of the Governance Committee by current Board members, management, stockholders or other persons. All potential new candidates are fully evaluated by the Governance Committee using the criteria described above, and then considered by the entire Board for nomination.

Director Candidates submitted by Stockholders: Stockholders wishing to recommend director candidates for consideration by the Governance Committee may do so by writing to the Chairman of the Governance/Nominating Committee, c/o Corporate Secretary, Gartner, Inc., 56 Top Gallant Road, P.O. Box 10212, Stamford, CT 06904-2212, and indicating the recommended candidate’s name, biographical data, professional experience and any other qualifications. In addition, stockholders wishing to propose candidates for election must follow our advance notice provisions. See Process for Submission of Stockholder Proposals for our 2020 Annual Meeting on page 55.

Code of Ethics and Code of Conduct

Gartner has adopted a CEO & CFO Code of Ethics which applies to our CEO, CFO, controller and other financial managers, and a Global Code of Conduct, which applies to all Gartner officers, directors and employees, wherever located. Annually, each officer, director and employee affirms compliance with the Global Code of Conduct. See Miscellaneous—Available Information below.

PROPOSAL ONE:

ELECTION OF DIRECTORS

Nominees for Election to the Board of Directors

Our Board, acting through the Governance Committee, is responsible for presenting for stockholder consideration each year a group of nominees that, taken together, has the experience, qualifications, attributes and skills appropriate and necessary to carry out the duties and responsibilities of, and to function effectively as, the board of directors of Gartner. The Governance Committee regularly reviews the composition of the Board in light of the needs of the Company, its assessment of board and committee performance, and the input of stockholders and other key stakeholders. The Governance Committee looks for certain common characteristics in all nominees, including integrity, strong professional experience and reputation, a record of achievement, constructive and collegial personal attributes and the ability and commitment to devote sufficient time and effort to board service. In addition, the Governance Committee seeks to include on the Board a complementary mix of individuals with diverse backgrounds and skills that will enable the Board as a whole to effectively manage the array of issues it will confront in furtherance of its duties. These individual qualities can include matters such as experience in the technology industry; experience managing and operating large public companies; international operating experience; financial, accounting, executive compensation and capital markets expertise; and leadership skills and experience.

All of the nominees listed below are incumbent directors who have been nominated by the Governance Committee and Board for re-election, and have agreed to serve another term. For additional information about the nominees and their qualifications, please see General Information About Our Board of Directors on page 6 above. If any nominee is unable or declines unexpectedly to stand for election as a director at the Annual Meeting, proxies may be voted for a nominee designated by the present Board to fill the vacancy. Each person elected as a director will continue to be a director until the 2020 Annual Meeting of Stockholders or a successor has been elected.

RECOMMENDATION OF OUR BOARD

Our Board unanimously recommends that you vote FOR the election of each nominee

to the Board of Directors.

General Information about our Current Executive Officers:

COMPENSATION DISCUSSION & ANALYSIS

This Compensation Discussion & Analysis, or “CD&A”, describes and explains the Company’s compensation philosophy and executive compensation program, as well as compensation awarded to and earned by, the following persons who were Named Executive Officers (“NEOs”) in 2018:

The CD&A is organized into three sections:

EXECUTIVE SUMMARY

2018 - A Year of Strong Performance

2018 was an exciting year for Gartner. Following our 2017 acquisitions of CEB and L2, 2018 was the first full year of Gartner providing insight and advice to clients across all enterprise functions. Our expanded product offering enhanced our ability to provide more value to our clients and broadened our addressable market significantly.

In 2018, most of our businesses performed at or near record levels. Our Contract Value grew 11.4% on an FX neutral basis, with the Contract Value of Global Technology Sales, which accounted for 81% of our Contract Value in 2018, growing at 14.2% year over year. Our Conferences business (formerly called “Events”) revenue grew 19% year over year, on an FX neutral basis, the highest growth rate in the Company’s history. Our Consulting business had a strong year as well, with revenue up 7% and backlog up 12% on an FX neutral basis.

In 2018, we also completed the disposition of certain non-core assets that we acquired in connection with the 2017 CEB acquisition. We used the proceeds to rapidly de-lever, reducing our debt balance by $1 billion. We additionally resumed the share repurchase program, purchasing over $260 million of our stock in the year.

We made a number of important investments in 2018 to help strengthen the foundation for future growth. They included investments in sales capacity and enabling infrastructure functions, which we expect will help us accelerate growth. We believe that our business trends going into 2019 are strong and we are well-positioned to achieve another successful year in 2019.

Contract Value–A Unique Key Performance Metric for Gartner

Unique to Gartner, Contract Value is our single most important performance metric. It focuses all of our executives on driving both short-term and long-term success for our business and stockholders.

Comparing CV year over year measures the short-term growth of our business, and, more importantly, also signals the long–term health of our Research subscription business. We believe that CV is our best, most informed and leading indicator of long-term Research revenue growth.

Our Research business comprises 80% of our overall revenue and is also our highest contribution margin business (69% for 2018). Further, many of our Research contracts are multi-year agreements, and our Research enterprise client retention and retained contract value (or wallet retention) are consistently very high. As a result, CV is predictive of revenue highly likely to recur over a 3 – 5 year period, and a high CV growth rate translates to high, long-term revenue and profit growth. In addition, our clients pay us upfront when they purchase our research subscription, which drives strong cash flow. For all these reasons, the Board believes that Research revenue growth is the most important driver of the Company’s profit growth.

Accordingly, growing CV drives both short-term and long-term corporate performance and shareholder value. As such, all Gartner executives and associates are focused at all times on growing CV. This, coupled with the fact that our investors are also focused on this metric, ensures that we are aligned on the long-term success of the Company.

Our strong results have fueled stock price growth which compared favorably to comparison groups as shown below.

Key Attributes of our Executive Compensation Program – Pay for Performance

Our Compensation Best Practices

COMPENSATION SETTING PROCESS FOR 2018

This discussion explains the objectives of the Company’s compensation policies; what the compensation program is designed to reward; each element of compensation and why the Company chooses to pay each element; how the Company determines the amount (and, where applicable, the formula) for each element of pay; and how each

compensation element and the Company’s decisions regarding that element fit into the Company’s overall compensation objectives and affect decisions regarding other elements.

The Objectives of the Company’s Compensation Policies

What the Compensation Program Is Designed to Reward

Our guiding philosophy is that the more executive compensation is linked to corporate performance, the stronger the inducement is for management to strive to improve Gartner’s performance. In addition, we believe that the design of the total compensation package must be competitive with the marketplace from which we hire our executive talent in order to achieve our objectives and attract and retain individuals who are critical to our long-term success. Our compensation program for executive officers is designed to compensate individuals for achieving and exceeding corporate performance objectives. We believe this type of compensation encourages outstanding team performance (not simply individual performance), which builds stockholder value.

Both short-term and long-term incentive compensation is earned by executives only upon the achievement by the Company of certain measurable performance objectives that are deemed by the Compensation Committee and management to be critical to the Company’s short-term and long-term success. The amount of compensation ultimately earned will increase or decrease depending upon Company performance and the underlying price of our Common Stock (in the case of long-term equity-based incentive compensation).

Principal Compensation Elements and Objectives

To achieve the objectives noted above, we have designed executive compensation to consist of three principal elements:

How the Company Determines Executive Compensation

In General

The Company set aggressive performance goals in planning 2018 executive compensation. In order for our executives to earn target compensation, the Company needed to exceed double digit growth in two key performance metrics, as discussed below.

The Compensation Committee established performance objectives for short-term (bonus) and long-term (equity) incentive awards at levels that it believed would motivate performance and be adequately challenging. The target performance objectives were intended to compel the level of performance necessary to enable the Company to achieve its operating plan for 2018.

The Compensation Committee believes that using a one-year performance measure for our long-term incentive awards helps accelerate growth and sustained performance. If we have a strong year, the goals for the following year are established on top of the high bar that was already set. If we had a three-year performance measure and the Company overachieved in the first year, the bar would be set lower in years 2 and 3 and may demotivate our associates. A three-year performance period may also be less aggressive if business cycle risks are factored into long-term goals, while a one-year performance period allows us to more readily factor in changes in market conditions.

The short-term and long-term incentive objectives provide executives with opportunity to increase their total compensation package based upon the over-achievement of Company performance; similarly, in the case of under-achievement of corporate performance, the value of incentive awards will fall below their target value, decreasing the total compensation opportunity. In addition, we assign a greater weighting to long-term incentives than short-term awards in order to promote long-term decision-making to deliver top corporate performance, align management to stockholder interests and retain executives. We believe that long-term equity-based awards with vesting terms that are based on the achievement of pre-set financial targets serve as a strong retention incentive.

Determining Awards

Salary, short-term and long-term incentive compensation levels for executive officers (other than the CEO) are recommended by the CEO and are subject to approval by the Compensation Committee. In formulating his recommendation to the Compensation Committee, the CEO undertakes a performance review of these executives and considers input from human resources personnel at the Company, as well as benchmarking data from the compensation consultant and external market data (discussed below).

Salary, short-term and long-term incentive compensation levels for the CEO’s compensation are established by the Compensation Committee within the parameters of Mr. Hall’s employment agreement with the Company. In making its determination with respect to Mr. Hall’s compensation, the Compensation Committee evaluates his performance in conjunction with the Governance Committee and after soliciting additional input from the Chairman of the Board and other directors; considers input from the Committee’s compensation consultant; and reviews benchmarking data pertaining to CEO compensation practices at our peer companies and general trends. See Employment Agreements with Executive Officers – Mr. Hall below for a detailed discussion of Mr. Hall’s agreement.

Effect of Stockholder Advisory Vote on Executive Compensation, or Say on Pay

The Board has resolved to present Say on Pay proposals to stockholders on an annual basis, respecting the sentiment of our stockholders as expressed in 2017. The Company and the Compensation Committee will consider the results on this year’s advisory Say on Pay proposal in future executive compensation planning activities. Over the past several years, stockholders have consistently strongly supported our executive compensation program. We also engage our stockholders periodically to solicit their feedback on executive compensation and corporate governance matters. As such, no changes were made to the core structure of our compensation program as a result of the 2018 Say on Pay vote.

Benchmarking and Peer Group

Executive compensation planning for 2018 began mid-year in 2017. Our Compensation Committee commissioned Exequity, an independent compensation consultant, to perform a competitive analysis of our executive compensation practices (the “Compensation Study”). Exequity’s findings were considered by the Compensation Committee and by management in planning our 2018 executive compensation program. The Compensation Study utilized market data provided by Aon Hewitt pertaining to compensation paid to individuals occupying senior executive positions at Gartner’s selected peer group of companies for executive compensation benchmarking purposes (the “Peer Group”), effective as of January 1, 2018.

The Compensation Committee reviews the Peer Group annually to ensure comparability based on Gartner’s operating characteristics, labor market relevance and defensibility. The 2018 competitive analysis compared Gartner’s target compensation to the Peer Group. The Peer Group comprised 16 publicly-traded companies that resemble Gartner in size (in terms of revenues and number of employees), have a similar business model and with whom Gartner competes for executive talent. Gartner ranked at the 69th percentile in revenues relative to the Peer Group. Peer Group companies included:

Management and the Compensation Committee concluded that the Peer Group, which was established in mid-2017, was appropriate for 2018 executive compensation planning purposes given comparability to Gartner.

The Compensation Committee does not target NEO’s pay to a specified percentile relative to the Peer Group, but rather reviews Peer Group market data at the 25^th, 50^th and 75^th percentile for each element of compensation, including Base Salary, Target Total Cash (Base Salary, plus Target Bonus) and Target Total Compensation (Target Total Cash plus long-term incentives).

The result of the competitive analysis indicated that Gartner’s 2017 aggregate NEO (including CEO) Base Salary approximated the Peer Group median, whereas Target Total Cash and Target Total Compensation trailed the median, with variance in positioning by executive. In order to remain competitive in the market place and in light of Gartner’s philosophy to pay a greater percentage of total compensation in the form of performance-based compensation and, in particular, performance-based long-term incentive compensation, the Committee approved a 3.2 % merit increase to base salary for Messrs. Dawkins and McVeigh and a 3% increase to base salary for Ms. Kranich, as well as a 5% point increase to target bonus and a 10.8% merit increase to the annual long-term incentive compensation award value for these three NEOs for 2018. Mr. Hall received an 11.0% merit increase to his annual long-term incentive award value only. Mr. Safian is still relatively new in his role of CFO, and as a result trailed the market median of the Peer Group in all elements of compensation. Consistent with the Company’s philosophy of moving executives to fully competitive rates over time, the Committee adjusted his compensation by increasing his base salary by 4.5%, his target bonus percent by 5%, and increased his annual long-term incentive award value by 25.8%. The table below summarizes the increases in each element of compensation for 2018 approved by the Compensation Committee:

In addition, the Compensation Committee annually reviews an analysis conducted by Exequity that evaluates the connection between Gartner’s executive pay and Company performance as measured by Total Shareholder Return and Shareholder Value against the relationship exhibited by the Peer Group. The analysis indicates that pay realized by Gartner’s NEOs is generally well aligned with Company performance. Gartner has historically performed above the peer group median and has paid at or above median total compensation, which is consistent with the Company’s pay-for-performance philosophy.

We continue to move the pay ratio of our CEO to the next highest paid NEO towards 3 to 1 and the pay ratio of our CEO to the average of all the other NEOs towards 4 to 1. For our current NEOs, following the compensation changes in 2019, we expect these pay ratios to be under 3 to 1 and 4 to 1, respectively, on a go forward basis.

Executive Compensation Elements Generally

Pay Mix

The following charts illustrate the relative mix of target compensation elements for the NEOs in 2018. Long-term incentive compensation consists of PSUs, SARs and time-based restricted stock units (RSUs), and represents a majority of the compensation we pay to our NEOs – 83% to the CEO and 66% to all other NEOs. We weigh compensation more heavily to long-term incentives because we believe that it contributes to a greater degree to the delivery of top performance and the retention of employees than does cash and short-term compensation (bonus).

Base Salary

We set base salaries of executive officers when they join the Company or are promoted to an executive role, by evaluating the responsibilities of the position, the experience of the individual and the marketplace in which we compete for the executive talent we need. In addition, where possible, we consider salary information for comparable positions for members of our Peer Group or other available benchmarking data. In determining whether to award salary merit increases, we consider published projected U.S. salary increase data for the technology industry and general market, as well as available world-wide salary increase data. Mr. Hall’s salary increase is established each year by the Compensation Committee after completion of Mr. Hall’s performance

evaluation for the preceding year. The following table sets forth the 2017 and 2018 base salary of each NEO and the corresponding year-over-year percentage increase:

Short-Term Incentive Compensation (Cash Bonuses)

All bonuses to executive officers are awarded pursuant to Gartner’s stockholder-approved Executive Performance Bonus Plan. This plan is designed to motivate executive officers to achieve goals relating to the performance of Gartner, its subsidiaries or business units, or other objectively determinable goals, and to reward them when those objectives are satisfied. We believe that the relationship between proven performance and the amount of short-term incentive compensation paid promotes, among executives, decision-making that increases stockholder value and promotes Gartner’s success.

In 2018, bonus targets for all NEOs, including Mr. Hall, were based solely upon achievement of 2018 company-wide financial performance objectives (with no individual performance component). The financial objectives and weightings used for 2018 executive officer bonuses were:

Management and our Compensation Committee continue to believe that EBITDA and CV are the most significant measurements of profitability and long-term business growth for our Company, respectively. They have been successfully used for several years as performance metrics applicable to short-term incentive compensation that drive business performance and that motivate executive officers to achieve outstanding performance.

For 2018, each executive officer was assigned a bonus target that was expressed as a percentage of salary, which varied from 65% to 105% of salary depending upon the executive’s level of responsibility and in most cases was 5% greater than the previous year. With respect to our NEOs, 2018 bonus targets as a percentage of base salary, were 105% for Mr. Hall and 80% for each of Messrs. Safian, Dawkins, McVeigh and Ms. Kranich. The maximum payout for 2018 bonus was 200% of target if the maximum level of EBITDA and CV were achieved; the minimum payout was $0 if minimum levels were not achieved. The following table sets forth the threshold, target and maximum payout amounts for each NEO:

The chart below describes the performance metrics applicable to our 2018 short–term incentive compensation element. When adopting these financial metrics, the Compensation Committee expressly reserved the authority to adjust the performance goals to reflect the effect of any merger, acquisition and divestiture activity. In February 2019, the Compensation Committee certified that the results for each performance metrics under the bonus plan were as follows:

The Contract Value results in the table above translated to a payout percentage of 143.5%. For the EBITDA component, the results above translated to a payout percentage of 91.3%. Since each objective was weighted 50%, based on these results, the Compensation Committee determined that earned cash bonuses for each NEO were 117.4% of target bonus amounts. These bonuses were paid in February 2019. See Summary Compensation Table – Non-Equity Incentive Plan Compensation for the amount of cash bonuses earned by our NEOs in 2018.

Long-Term Incentive Compensation (Equity Awards)

Promoting stock ownership is a key element of our compensation program philosophy. Stock-based incentive compensation awards – especially when they are assigned a combination of performance and time-based vesting criteria–induce enhanced performance, promote retention of executive officers and align executives’ personal rewards with long-term stock price appreciation, thereby integrating management and stockholder interests. We have evaluated different types of long-term incentives based on their motivational value, cost to the Company and appropriate share utilization under our stockholder-approved 2014 Long-Term Incentive Plan (“2014 Plan”) and have determined that generally stock-settled stock appreciation rights (“SARs”) and performance-based restricted stock units (“PSUs”) create the right balance of motivation, retention, alignment with stockholders and share utilization.

SARs permit executives to benefit from an increase in stock price over time. SAR value can be realized only after the SAR vests. Our SARs are stock-settled and vested SARs may be exercised up to seven years from grant date. When the SAR is exercised, the executive receives shares of our Common Stock equal in value to the aggregate appreciation in the price of our Common Stock from the date of grant to the exercise date for all SARs exercised. Therefore, SARs only have value to the extent the price of our Common Stock exceeds the grant price of the SAR. In this way, SARs motivate our executives to increase stockholder value and thus align their interests with those of our stockholders.

PSUs offer executives the opportunity to receive our Common Stock contingent on the achievement of performance goals and continued service over the vesting period. PSU recipients are eligible to earn a target fixed number of restricted stock units if and to the extent stipulated one-year performance goals are achieved. They can earn more units if the Company over-performs (up to 200% of their target number of units), and they will earn fewer units (and potentially none) if the Company under-performs. PSUs encourage executives to increase stockholder value while promoting executive retention over the long-term. Released shares have value even if our Common Stock price does not increase, which is not the case with SARs.

Consistent with weightings in prior years, when the compensation program was established in early 2018, 30% of each executive’s long-term incentive compensation award value was granted in SARs and 70% was granted in

PSUs. PSUs deliver value utilizing fewer shares since the executive can earn the full share rather than just the appreciation in value over the grant price (as is the case with SARs). Additionally, the cost efficiency of PSUs enhances the Company’s ability to conservatively utilize the 2014 Plan share pool, which is why we conveyed a larger portion of the 2018 overall long-term incentive compensation value in PSUs rather than in SARs. For purposes of determining the number of SARs awarded, the allocated SAR award value is divided by the Black-Scholes-Merton valuation on the date of grant using assumptions appropriate on that date. For purposes of determining the target number of PSUs awarded, the allocated target PSU award value is divided by the closing price of our Common Stock on the date of grant as reported by the New York Stock Exchange.

All SARs and PSUs are earned, vest and, with respect to PSUs, release 25% per year commencing one (1) year from grant and on each anniversary thereof, subject to continued service on the applicable vesting date. We believe that this vesting schedule effectively focuses our executives on delivering long-term value growth for our stockholders and drives retention. The maximum payout for the 2018 PSUs was 200% of target if the maximum level of CV was achieved; the PSUs are subject to forfeiture if minimum levels of performance are not achieved.

The Compensation Committee approved CV (measured at December 31, 2018) as the performance measure underlying PSUs awarded in 2018. As noted earlier, we continue to believe that CV is the best performance metric to measure the long–term prospects of our business because it is predictive of future revenue.

The chart below describes the performance metrics applicable to the PSU portion of our 2018 long–term incentive compensation element measured on a foreign exchange neutral basis. When adopting the performance metrics, the Compensation Committee expressly reserved the authority to adjust the performance goals to reflect the effect of any merger, acquisition and divestiture activity. In February 2019, the Compensation Committee certified the result as follows:

The CV target represented double digit growth. Actual CV certified by the Compensation Committee in early 2019 was $3,164 million, exceeding the target amount. Based on this, the Compensation Committee determined that 143.5% of the target number of PSUs was earned based on the established performance goals. The PSUs were adjusted by this factor in early 2019 after certification of the achievement of this performance measure by the Compensation Committee, and 25% of the adjusted awards vested on the first anniversary of the grant date. See Grants of Plan-Based Awards Table – Possible Payouts Under Equity Incentive Plan Awards and accompanying footnotes below for the actual number of SARs and PSUs awarded to our NEOs in 2018.

Additional Compensation Elements

We maintain a non-qualified deferred compensation plan for our highly compensated employees, including our executive officers, to assist eligible participants with retirement and tax planning by allowing them to defer compensation in excess of amounts permitted to be deferred under our 401(k) plan. This plan allows eligible participants to defer up to 50% of base salary and/or 100% of bonus to a future period. In addition, as a further inducement to participation in this plan, the Company presently matches contributions by executive officers, subject to certain limits. For more information concerning this plan, see Non-Qualified Deferred Compensation Table and accompanying narrative and footnotes below.

In order to further achieve our objective of providing a competitive compensation package with great retention value, we provide various other benefits to our executive officers that we believe are typically available to, and expected by, persons in senior business roles. Our basic executive perquisites program includes 35 days paid time off (PTO) annually, severance and change in control benefits (discussed below) and relocation services where necessary due to a promotion. Mr. Hall’s perquisites, severance and change in control benefits are governed by his employment agreement with the Company, which is discussed in detail below under Employment Agreements With Executive Officers – Mr. Hall. For more information concerning perquisites, see Other Compensation Table and accompanying footnotes below.

OTHER COMPENSATION POLICIES AND INFORMATION

Executive Stock Ownership and Holding Period Guidelines

In order to align management and stockholder interests, the Company has adopted stock ownership guidelines for our executive officers as follows: the CEO is required to hold shares of Common Stock with a value at least equal to six (6) times his base salary, and all other executive officers are required to hold shares of Common Stock with a value at least equal to three (3) times their base salary. For purposes of computing the required holdings, officers may count shares directly held, as well as vested and unvested restricted stock units and PSUs, but not options or SARs.

Additionally, the Company imposes a holding period requirement on our executive officers. If an executive officer of the Company is not in compliance with the stock ownership guidelines, the executive is required to maintain ownership of at least 50% of the net after-tax shares of Common Stock acquired from the Company pursuant to all equity-based awards received from the Company, until such individual’s stock ownership requirement is met. At December 31, 2018, all the NEOs were in compliance with these guidelines.

Clawback Policy

The Company has adopted a clawback policy which provides that the Board of Directors (or a committee thereof) may seek recoupment to the Company from a current or former executive officer of the Company who engages in fraud, omission or intentional misconduct that results in a required restatement of any financial reporting under the securities or other laws, and that the cash-based or equity-based incentive compensation paid to the officer exceeds the amount that should have been paid based upon the corrected accounting restatement, resulting in an excess payment. Recoupment includes the reimbursement of any cash-based incentive compensation (bonuses) paid to the executive, cancellation of vested and unvested performance-based restricted stock units, stock options and stock appreciation rights, and reimbursement of any gains realized on the sale of released stock unit awards and the exercise of stock options or stock appreciation rights and subsequent sale of underlying shares.

Pursuant to the Dodd-Frank Act, the SEC has issued proposed rules applicable to the national securities exchanges (including the NYSE on which our Common Stock is listed for trading) prohibiting the listing of any security of an issuer that does not provide for the recovery of erroneously awarded incentive-based compensation where there has been an accounting restatement. We are awaiting adoption of the final SEC rules on this matter, at which time we will determine whether an amendment to our policy is necessary.

Hedging and Pledging Policies

The Company’s Insider Trading Policy prohibits all directors, executive officers and other employees from engaging in any short selling, hedging and/or pledging transactions with respect to Company securities.

Accounting and Tax Impact

In setting 2018 compensation, the Compensation Committee and management considered that for taxable years beginning after December 31, 2017, the exemption from Code Section 162(m)’s deduction limit that formerly existed for certain “performance-based” compensation was repealed (except for certain grandfathered compensation arrangements that were in effect as of November 2, 2017). Accordingly, we expect that compensation awarded to our executives who are “covered employees” under Section 162(m) in 2018 and subsequent years will not be deductible to the extent that it results in compensation above the $1 million threshold established under Section 162(m). Furthermore, the rules and regulations promulgated under Section 162(m) are complicated and subject to change. As such, there can be no assurance that any grandfathered compensation awarded in prior years will be fully tax deductible when paid. .Notwithstanding repeal of the exemption for “performance-based” compensation, the Compensation Committee intends to operate our executive compensation program in a manner that they believe best aligns compensation with our pay-for-performance philosophy.

Grant of Equity Awards

The Board of Directors has a formal policy with respect to the grant of equity awards under our equity plans. Under our 2014 Plan, equity awards may include stock options, stock appreciation rights, restricted stock awards (RSAs), restricted stock units (RSUs) and performance-based restricted stock units. The Compensation Committee may not delegate its authority with respect to Section 16 persons, nor in any other way which would jeopardize the plan’s qualification under Code Section 162(m) (as in effect prior to 2018 for grandfathered awards) or Exchange Act Rule 16b-3. Accordingly, our policy specifies that all awards to our Section 16 executive officers must be approved by the Compensation Committee on or prior to the award grant date, and that all such awards will be made and priced on the date of Compensation Committee approval, except in the case of new hires, which is discussed below.

Consistent with the 2014 Plan, the Compensation Committee annually approves a delegation of authority to the CEO to make equity awards under our equity Plan to Gartner employees (other than Section 16 reporting persons) on account of new hires, retention or promotion without the approval of the Compensation Committee. In 2018, the delegation of authority specified a maximum grant date award value of $500,000 per individual, and a maximum aggregate grant date award value of $5,000,000 for the calendar year. For purposes of this computation, in the case of RSAs, RSUs and PSUs, value is calculated based upon the fair market value (defined as the closing price on the date of grant as reported by the New York Stock Exchange) of a share of our Common Stock, multiplied by the number of RSAs, RSUs or PSUs awarded. In the case of options and SARs, the grant date value of the award will be the Black-Scholes-Merton calculation of the value of the award using assumptions appropriate on the award date. Any awards made under the CEO-delegated authority are reported to the Compensation Committee at the next regularly scheduled committee meeting.

As discussed above, the structure and value of annual long-term incentive awards comprising the long-term incentive compensation element of our compensation package to executive officers are established and approved by the Compensation Committee in the first quarter of each year. The specific terms of the awards (number of PSUs and SARs and related performance criteria) are determined, and the awards are approved and made, on the same date and after the release of the Company’s prior year financial results.

It is the Company’s policy not to make equity awards to executive officers prior to the release of material non-public information. Generally speaking, awards for newly hired executives that are given as an inducement to joining the Company are made on the 15^th or 30^th day of the month first following the executive’s start date, and retention and promotion awards are made on the 15^th or 30^th day of the month first following the date of Compensation Committee approval; however, we may delay making these awards pending the release of material non-public information.
