Notice of 2018 Annual Meeting

of Stockholders

We also believe that all of our director nominees have a reputation for honesty and adherence to high ethical standards. Each agreed to be named in this Proxy Statement and to serve if elected.

Our by-laws provide that our Board may not nominate (i) more than one member of the company’s current management to serve on the Board at any one time or (ii) any non-management director for re-election to the Board if that director has completed 12 years of service as an independent member of the Board.¹ Our Board believes that these restrictions contribute to Board stability, vitality and diversity and help ensure that our Board continuously benefits from a balanced mix of perspectives and experiences. Our focus on Board refreshment has resulted in the addition of five new directors since October 2015.

Our Board seeks directors who represent a mix of backgrounds and experiences that will enhance the quality of our Board’s deliberations and decisions. In nominating candidates, our Board considers a diversified membership in the broadest sense, including persons diverse in experience, gender and ethnicity. Our Board does not discriminate on the basis of race, color, national origin, gender, religion, disability or sexual preference. When evaluating candidates, our Board considers whether potential nominees possess integrity, accountability, informed judgment, financial literacy, mature confidence and high-performance standards.

Our Board is especially interested in adding candidates over time who are operating executives (particularly current chief executives or other operating executives of other large public companies) or who have a strong technology background and in both cases a passion for building a transformative business on a global basis. Other factors include having directors with international experience, including knowledge of emerging markets or management of business operations and resources

that are dispersed across a global platform. In addition, a majority of our Board must be independent, consistent with our Corporate Governance Guidelines and New York Stock Exchange (“NYSE”) listing standards. Further, at least one member of our Board should have the qualifications and skills necessary to be considered an “Audit Committee Financial Expert” under Section 407 of the Sarbanes-Oxley Act, as defined by the rules of the Securities and Exchange Commission (“SEC”).

The Corporate Governance and Nominating Committee of our Board of Directors, or the Governance Committee, is, among other things, responsible for identifying and evaluating potential candidates and recommending candidates to our Board for nomination, as well as performing assessments of the skills and experience needed to properly oversee our interests.

The Governance Committee regularly reviews the composition of our Board and determines whether the addition of directors with particular experience, skills or characteristics would make our Board more effective. When a need arises to fill a vacancy, or it is determined that a director possessing particular experiences, skills or characteristics would make our Board more effective, the Governance Committee conducts targeted efforts to identify and recruit individuals who have the identified qualifications. As a part of the search process, the Governance Committee may consult with other directors and members of our senior management and also may hire a search firm to assist in identifying and evaluating potential candidates.

All potential candidates are interviewed by our CEO, our Board Chair, our Governance Committee Chair and, to the extent practicable, the other members of the Governance Committee, and may be interviewed by other directors and members of senior management as desired and as schedules permit. In addition, the General Counsel reviews a director questionnaire submitted by the candidate, and a background and reference check is conducted as appropriate. The Governance Committee then meets to consider and approve the final candidates, and either makes its recommendation to the Board to fill a vacancy and to add an additional Board

member, or recommends a slate of candidates to the Board for nomination for election to the Board. The selection process for candidates is intended to be flexible, and the Governance Committee, in the exercise of its discretion, may deviate from the selection process when particular circumstances so warrant.

The Governance Committee will also consider candidates recommended to our Board by our stockholders. See “Corporate Governance—Stockholder Recommendations and Nominations of Director Candidates—Stockholder Recommendations” on page 16 for more information.

We believe our director nominees bring a well-rounded variety of experiences, qualifications, attributes and skills, and represent a mix of deep knowledge of the company and fresh perspectives. The director skills matrix below represents some of the key skills that our Board has identified as particularly valuable to the effective oversight of our company and the execution of our corporate strategy. This skills matrix highlights the depth and breadth of the skills of

our director nominees. This director skills matrix is not intended to be an exhaustive list of each of our director nominees’ skills or contributions to the Board. Further information on each director nominee, including some of their specific experience, qualifications, attributes and skills is set forth in the biographies on pages 10 to 13 of this Proxy Statement.

We are governed by a Board and committees of the Board that meet several times throughout the year, and we are committed to maintaining the highest standards of business conduct and corporate governance. Governance is a continuous focus for us, starting with our Board and extending to management and our employees. Our Board has also established Corporate Governance Guidelines that provide a framework for the effective governance of the company.

In January 2017, our Board adopted proxy access for director nominations, which allows eligible stockholders to nominate

directors and include those nominees in our proxy materials. As set forth in our by-laws, a group of up to 20 stockholders who beneficially own at least 3% of our outstanding common stock in the aggregate and who have held their shares for at least three years may submit nominees. The maximum number of director nominees included in our proxy materials pursuant to this process shall be the greater of (i) 20% of the total number of directors serving in office at the deadline for nominations (rounded down to the nearest whole number) and (ii) two.

The Governance Committee identifies and evaluates potential candidates and recommends candidates to our Board for nomination. For greater detail about the criteria for director

candidates and the nomination process, see “Proposal 1—Elect Directors—Director Nomination Criteria: Qualifications, Skills and Experience” on page 8.

Stockholder Recommendations

If you are a stockholder who would like to recommend a candidate for our Governance Committee to consider for possible inclusion in our 2019 proxy statement, you must send notice to Laurence H. Midler, Secretary, CBRE Group, Inc., 400 South Hope Street, 25^th Floor, Los Angeles, California 90071, by registered, certified or express mail, and provide him with a brief biographical sketch of the recommended candidate, a document indicating the recommended candidate’s willingness to serve if elected, and evidence of your stock ownership. The Governance Committee or its chair will then consider the recommended director candidate in accordance with the criteria for director selection described under “Proposal 1—Elect Directors—

Director Nomination Criteria: Qualifications, Skills and Experience” on page 8.

Stockholder Nominations

Stockholders who wish to nominate directors directly at an annual meeting should follow the instructions under “Submission of Stockholder Proposals and Board Nominees” on page 25. As discussed under “—Stockholder Director Nominations for Inclusion in the 2019 Proxy Statement” on page 25, our by-laws allow stockholders to submit director nominations to be included in our proxy materials. A stockholder who wishes to nominate a candidate and have that candidate included in our proxy materials must follow the procedures described in Article I, Section 12 of our by-laws.

Pursuant to our Board’s Corporate Governance Guidelines and the listing standards of the NYSE, our Board must consist of a majority of independent directors. In addition, all members of the Audit and Finance Committee, Compensation Committee and Governance Committee must be independent directors as defined by our Corporate Governance Guidelines and NYSE listing standards. Members of the Compensation Committee must also meet applicable NYSE independence requirements for compensation committee members, and members of the Audit and Finance Committee must further satisfy a separate SEC independence requirement, which generally provides that they may not (i) accept directly or indirectly any consulting, advisory or other compensatory fee from us or any of our subsidiaries, other than their compensation as directors or members of the Audit and Finance Committee or any other committees of our Board or (ii) be an affiliated person of ours.

Our Board regularly conducts a review of possible conflicts of interest and related-party transactions through the use of questionnaires, director self-reporting and diligence conducted by management. This review includes consideration of any investments and agreements between directors and their related persons and the company, including those described under “Related-Party Transactions” in this Proxy Statement, and such person’s beneficial ownership of our securities. The Board has determined that 90% of our director nominees (all except for Mr. Sulentic) are independent in accordance with NYSE listing standards and our Board’s Categorical Independence Standards that it has adopted relating to our director independence. These Categorical Independence Standards are posted on the Corporate Governance section of the Investor Relations page on our website at www.cbre.com.

Our non-management directors meet in executive session without management present each time the full Board convenes for a regularly scheduled meeting. If our Board convenes for a special meeting, the non-management

directors will meet in executive session if circumstances warrant. The Chair of our Board is a non-management director that presides over executive sessions of our Board.

In uncontested elections, directors are elected by a “majority vote” requirement. Under this requirement, in order for a nominee to be elected in an uncontested election, the nominee must receive the affirmative vote of a majority of the votes cast in his or her election (i.e., votes cast “FOR” a nominee must exceed votes cast as “AGAINST”). Votes to “ABSTAIN” with respect to a nominee and broker non-votes

are not considered votes cast, and so will not affect the outcome of the nominee’s election.

The company maintains a plurality vote standard in contested director elections, where the number of nominees exceeds the number of directors to be elected.

Our Board’s Corporate Governance Guidelines require that directors tender their resignation upon a change of their employment. The Governance Committee will then consider whether the change in employment has any bearing on the

director’s ability to serve on our Board, our Board’s goals regarding Board composition or any other factors considered appropriate and relevant. Our Board will then determine whether to accept or reject the tendered resignation.

The Board may not nominate any non-management director for re-election to the Board if that director has completed 12 years of service as an independent member of the Board on or prior to the date of election to which such nomination relates. The application of this term-limit restriction does not go into

effect until December 17, 2020 for any of the company’s directors who were serving on the Board as of December 17, 2015. The Board believes that this restriction will contribute to Board stability and vitality.

Our Board currently consists of 12 directors, 10 of whom have been nominated for re-election. As previously noted, Messrs. Freeman and Malek currently serve on our Board, but will not stand for re-election and will retire from our Board following the expiration of their current terms at the Annual Meeting.

All of our directors are elected at each annual meeting of stockholders and hold office until the next election. Our Board has authority under our by-laws to fill vacancies and to increase or, upon the occurrence of a vacancy, decrease its size between annual meetings of stockholders.

The Board has determined that it is in the best interests of the company and its stockholders to set the size of the Board to 10 members effective as of the date of the Annual Meeting.

Our Board has appointed Mr. Boze to succeed Mr. Wirta as the Independent Chair of our Board, effective following the Annual Meeting, assuming Mr. Boze is re-elected at such meeting by our stockholders. Since 2001, we have separated the roles of CEO and Chair of the Board in recognition of the differences between the two positions. Our CEO is responsible for setting the strategic direction and overseeing the day-to-day leadership and performance of the company. The Chair of our Board, who is independent of management, provides oversight and guidance to our CEO. Although it has been our longstanding policy to have an independent Board Chair, we amended our by-laws in 2015 to require that the Board Chair be an independent director.

Oversight of Risk

• The Board oversees risk management.

• Board committees, which meet regularly and report back to the full Board, play significant roles in carrying out our Board’s risk oversight function.

• Company management is charged with managing risk through rigorous risk mitigation activities and strong internal controls.

Our Board regularly reviews information regarding our most significant strategic, operational, financial and compliance risks. Our Board maintains direct oversight over our enterprise risk management process rather than delegating this function to a Board or management committee. We maintain an executive risk committee chaired by our Chief Risk Officer and consisting of several other key senior executives responsible for identifying, assessing and managing our most significant risks. This executive risk committee reports to the CEO, and a detailed presentation is given on identified significant risks in connection with an annual General Counsel Report to the Board. Certain risks that are determined to be best managed directly by the Board versus management or that are in areas specific to a particular Board committee expertise are monitored and overseen at the Board or committee level as appropriate.

Although each committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire Board is regularly informed through committee chair reports about such risks. These reports are presented at every regularly scheduled Board meeting.

Our Board reviews management succession and development plans with the CEO on at least an annual basis. These plans include CEO succession in the event of an emergency or

retirement, as well as the succession plans for the CEO’s direct reports and other employees critical to our continued operations and success.

Our Board held four meetings during fiscal year 2017 to review significant developments, engage in strategic planning and act on matters requiring Board approval. In 2017, each incumbent director attended at least 80% percent of our Board meetings and meetings of committees on which he or she served (taken in the aggregate) during the period that he or

she served thereon. Our Board also conducted several lengthy strategic planning sessions with our management during 2017.

Our Board currently has four standing committees that met or acted by written consent during fiscal year 2017: the Audit and Finance Committee, the Compensation Committee, the Governance Committee and the Executive Committee.

Each committee (other than the Executive Committee) is composed entirely of directors whom our Board has determined to be independent under current NYSE standards. Each committee operates under a charter approved by our Board that sets out the purposes and responsibilities of the committee and that are published in the Corporate Governance section of the Investor Relations page on our website at www.cbre.com. In accordance with our Board’s Corporate Governance Guidelines, our Board and each of the Audit and Finance Committee, Compensation Committee and Governance Committee conducts an annual performance self-assessment with the purpose of increasing the effectiveness of our Board and its committees. The responsibilities of all of our Board committees are described below.

Audit and Finance Committee—The Audit and Finance Committee provides oversight of our accounting and financial reporting and disclosure processes; the adequacy of the systems of disclosure and internal control established by management; our compliance with legal and regulatory requirements; risk oversight and management generally; the audit of our financial statements; and the periodic review of our balance sheet management, borrowing and capital markets activities. Among other things, the Audit and Finance Committee: (i) retains, compensates, oversees and terminates the independent auditor and evaluates its independence and performance; (ii) approves all audit and any non-audit services performed by the independent auditor; (iii) reviews the results of the independent audit and internal audits as well as reports from our Chief Ethics and Compliance Officer, our Global Director of Assurance & Advisory and our Chief Digital & Technology Officer; (iv) reviews the independent auditor’s report describing our internal quality-control procedures and any material issues raised by the most recent

internal quality-control review or any inquiry by governmental authorities; (v) reviews financial statements and releases and guidance provided to analysts and rating agencies; and (vi) establishes procedures to handle complaints regarding accounting, internal controls or auditing matters.

All of the members of the Audit and Finance Committee are independent within the meaning of SEC regulations, the listing standards of the NYSE and our Board’s Corporate Governance Guidelines. Our Board has determined that each of Messrs. Feeny and Jenny, Ms. Reynolds and Dr. Tyson meets the qualifications of an “audit committee financial expert” in accordance with SEC rules and that they have the requisite accounting, related financial management and/or other relevant expertise, as described under “Proposal 1—Elect Directors” beginning on page 8.

Compensation Committee—The Compensation Committee oversees the development and administration of our executive compensation policies, plans and programs, including reviewing and approving compensation of our executive officers and any compensation contracts or arrangements with our executive officers. In addition, the Compensation Committee reviews the performance of our executive officers, including our CEO. Each of the members of the Compensation Committee qualifies as a “non-employee director” within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended, or the Exchange Act, and as an “outside director” for purposes of Section 162(m) of the Internal Revenue Code, and each of them is also independent within the meaning of the listing standards and rules of the NYSE applicable to members of compensation committees. For additional information on the responsibilities and activities of the Compensation Committee, including the Compensation Committee’s processes for determining

executive compensation, see the “Compensation Discussion and Analysis” section of this Proxy Statement beginning on page 31.

Governance Committee—The Governance Committee oversees our Board’s corporate governance procedures and practices, including the recommendations of individuals for service on our Board and recommendations to our Board regarding corporate governance matters and practices, including as to director compensation and directors’ and officers’ liability insurance. In addition, the Governance

Committee consults with our CEO regarding management succession planning. All of the members of the Governance Committee are independent within the meaning of the listing standards and rules of the NYSE.

Executive Committee—The Executive Committee implements policy decisions of our Board and is authorized to act on our Board’s behalf between meetings of our Board, including by approving certain transactions within dollar thresholds established by our Board.

Our director compensation policy provides for the following annual compensation for each of our non-employee directors:

In all cases, our non-employee directors may elect to receive shares of our common stock in lieu of cash payments (in like

amounts). Non-employee directors who are appointed or elected off-cycle (i.e., outside an annual meeting) receive a pro rata portion of their cash retainer and restricted stock unit grant based on the length of their service until the next annual meeting.

Our non-employee directors are eligible to defer their compensation through our Deferred Compensation Plan, as described under “Executive Compensation—Summary of Plans, Programs and Agreements—Deferred Compensation Plan” on page 62. We also reimburse our non-employee directors for all reasonable out-of-pocket expenses incurred in the performance of their duties as directors. Employee directors do not receive any fees for attendance at meetings or for their service on our Board.

Our Board also has adopted stock ownership requirements that are applicable to non-employee directors. A description of these stock ownership requirements can be found under “Stock Ownership Requirements” on page 23.

Our Board has adopted Standards of Business Conduct applicable to our directors, officers and employees as well as a Code of Ethics for Senior Financial Officers applicable to our CEO, Chief Financial Officer and Chief Accounting Officer. In addition, our Board has adopted Corporate Governance Guidelines, which set forth a framework within which our Board, assisted by its committees, directs our affairs.

Other key governance policies include:

Current copies of our Board’s Standards of Business Conduct, Code of Ethics for Senior Financial Officers, Corporate Governance Guidelines, Policy Regarding Transactions with Interested Parties and Corporate Opportunities, Whistleblower Policy and Equity Award Policy are available on our website and in print upon written request to our Investor Relations Department at CBRE Group, Inc., 200 Park Avenue, New York, New York 10166, or by email at investorrelations@cbre.com. If the Board grants any waivers from the Board’s Standards of Business Conduct or the Code of Ethics for Senior Financial Officers to any of our directors or executive officers, or if we amend such policies, we will, if required, disclose these matters through the Investor Relations section of our website on a timely basis.

In order to align the interests of our Board members and executives with the interests of our stockholders, our Board has adopted stock ownership requirements for non-employee directors, and the Compensation Committee has adopted executive officer stock ownership requirements that are applicable to all of our Section 16 officers.

Non-Employee Directors. Each non-employee director has a target minimum common stock ownership requirement of five times the value of the annual stock grants made by us to the non-employee director pursuant to our then current director compensation plan. If at any time the target common stock ownership requirement is not satisfied, the director must retain the shares remaining after payment of taxes and exercise price upon exercise of stock options, the vesting of restricted stock or the settlement of vested restricted stock units, as applicable. Shares that count toward compliance with the requirements include: shares owned outright by the director (either directly or beneficially, e.g., through a family trust); and shares issued upon the settlement of vested restricted stock units. Shares that do not count toward achievement of the requirements include: (i) shares held by mutual or hedge funds in which the non-employee director is a general partner, limited partner or investor; (ii) unexercised outstanding stock options (whether or not vested); (iii) unvested/unearned restricted stock units or restricted

stock; and (iv) shares transferred to a non-employee director’s employer pursuant to such employer’s policies.

Executive Officers. Depending on their positions, our executive officers have a target minimum common stock ownership requirement of two to five times their annual base salary. The CEO’s target minimum ownership requirement is five times his annual base salary, and the target minimum ownership requirement for our other named executive officers for 2017 is three times their annual base salary. If at any time an executive officer’s equity holdings do not satisfy these target minimum ownership requirements, depending on his or her position, the executive must retain 100% (for our CEO) or 75% (for our other named executive officers) of the shares remaining after payment of taxes and exercise price upon the exercise of stock options or upon the vesting of restricted stock or the settlement of vested restricted stock units, as applicable. Shares that count toward compliance with the requirements include: shares owned outright (either directly or indirectly); shares issued upon the settlement of vested restricted stock units; and allocated shares in other company benefit plans. Unexercised outstanding stock options (whether or not vested) and unvested/unearned restricted stock and restricted stock units do not count toward compliance with the requirements.

We view it as a priority to operate in an environmentally and socially responsible manner, and it is our practice to act responsibly in relationships with our stockholders, customers, suppliers, employees, communities and other stakeholders. The seven pillars of our Corporate Responsibility program are:

We believe that we can make the greatest impact by:

In 2017 and in early 2018, our corporate responsibility efforts were recognized with the following awards and accolades:

To learn more about our corporate responsibility and sustainability efforts, please view our Corporate Responsibility Report on www.cbre.com/responsibility.

Throughout each year, management and members of our Board engage with a significant portion of our stockholders through a number of forums, including quarterly earnings presentations, our annual meeting, our annual Investor Day, our annual Corporate Responsibility Report, investor conferences and web communications, as well as our SEC filings, our Annual Report and proxy statement.

We also have a formal corporate governance outreach program. This program covers a wide array of topics with a broad group of stockholders, and stockholder feedback is regularly provided to the Board and the company’s management. In 2017, topics of discussion included company strategy and performance, executive compensation, board

diversity and refreshment, corporate governance policies and corporate responsibility. In addition, in 2017, we sought stockholder input on two specific corporate governance issues: (i) the ability of stockholders to call a special meeting and (ii) board composition.

As a result of all of our stockholder engagement efforts, and after careful consideration of all relevant factors, we are submitting a proposal in this Proxy Statement asking our stockholders to reduce the ownership threshold for stockholders to call a special meeting from 30% to 25%. Stockholders that we spoke to generally expressed minimal concerns about our Board’s composition and indicated their continued support of individual directors.

Stockholders and other interested parties may write to the Chair of the Board (who acts as the lead independent director), the entire Board or any of its members at CBRE Group, Inc., c/o Laurence H. Midler, Executive Vice President, General Counsel and Secretary, 400 South Hope Street, 25^th Floor, Los Angeles, California 90071 or via email to larry.midler@cbre.com. The Board considers stockholder questions and comments to be important and endeavors to respond promptly and appropriately, even though the Board may not be able to respond to all stockholder inquiries directly.

The Board has developed a process to assist with managing inquiries and communications. The General Counsel will review any stockholder communications and will forward to the Chair of our Board, our Board or any of its members a summary and/or copies of any such correspondence that deals with the functions of our Board or committees thereof or that the General Counsel otherwise determines requires their attention. Certain circumstances may require that our Board depart from the procedures described above, such as the receipt of threatening letters or e-mails or voluminous inquiries with respect to the same subject matter.

If you would like to include a proposal for stockholder consideration in our 2019 proxy statement or bring business before our annual meeting of stockholders in 2019, you must send notice to Laurence H. Midler, Secretary, CBRE Group, Inc., 400 South Hope Street, 25^th Floor, Los Angeles, California 90071, by registered, certified, or express mail and provide the required information and follow the other procedural requirements as described below.

Stockholder Proposals for Inclusion in the 2019 Proxy Statement. Stockholders who wish to present a proposal in accordance with SEC Rule 14a-8 for inclusion in our proxy materials to be distributed in connection with our 2019 annual meeting of stockholders must submit their proposals in accordance with that rule so that they are received by the Secretary at the address set forth above no later than the close of business on December 6, 2018. If the date of our 2019 annual meeting is more than 30 days before or after May 18, 2019, then the deadline to timely receive such material shall be a reasonable time before we begin to print and send our proxy materials. Failure to deliver a proposal in accordance with this procedure may result in it not being deemed timely received. As the rules of the SEC make clear, simply submitting a timely proposal does not guarantee that it will be included in our proxy materials.

Stockholder Director Nominations for Inclusion in the 2019 Proxy Statement. Our by-laws permit any stockholder, or group of up to 20 stockholders, who has beneficially owned 3% or more of our outstanding common stock continuously for at least three years to submit director nominations to be included in our proxy materials. The maximum number of director nominees included in our proxy pursuant to this process (known as “proxy access”) shall be the greater of (i) 20% of the total number of directors serving in office at the deadline for nominations (rounded down to the nearest whole

number) and (ii) two. The notice required to nominate a director for the 2019 annual meeting through this proxy access process must be delivered to (or mailed to and received at) the address set forth above no later than February 17, 2019 and no earlier than January 18, 2019, unless our 2019 annual meeting of stockholders is to be held more than 30 days before, or more than 70 days after, May 18, 2019, in which case the stockholder’s notice must be delivered not earlier than the close of business on the 120th day prior to the 2019 annual meeting and not later than the close of business on the later of the 90th day prior to the 2019 annual meeting or the 10th day after public announcement of the date of the 2019 annual meeting is first made. The notice must set forth the information required by our by-laws with respect to each proxy access director nomination that eligible stockholder or stockholders intend to present at the 2019 annual meeting and must otherwise be in compliance with our by-laws.

Other Stockholder Proposals or Nominations for Presentation at the 2019 Annual Meeting. If a stockholder wishes to bring business to a meeting for consideration other than a matter brought pursuant to SEC Rule 14a-8, the stockholder must give our Secretary written notice of the stockholder’s intent to do so and provide the information required by the provision of our by-laws dealing with stockholder proposals. In addition, our by-laws allow stockholders to nominate one or more persons for election as directors outside of the proxy access process described above (although doing so relieves the company of the obligation to include a director nominee in the proxy materials prepared for the relevant stockholders meeting). The notice of such a proposal or director nomination must be delivered to (or mailed to and received at) the address set forth above no later than February 17, 2019 and no earlier than January 18, 2019, unless our 2019 annual meeting of stockholders is to be held more than 30 days before, or more than 70 days after,

May 18, 2019, in which case the stockholder’s notice must be delivered not earlier than the close of business on the 120th day prior to the 2019 annual meeting and not later than the close of business on the later of the 90th day prior to the 2019 annual meeting or the 10th day after public announcement of the date of the 2019 annual meeting is first made. In the event that the number of directors to be elected at the annual meeting is increased and no public announcement naming all of the nominees or specifying the size of the increased Board has been made by February 7, 2019, then notice of a stockholder’s nomination to fill the new position or positions may be delivered to (or mailed to and received at) the address set forth above no later than the close of business on the 10th

day after public announcement of such increase is first made. The requirements for such stockholder’s notice are set forth in our by-laws, which are posted in the Corporate Governance section of the Investor Relations page on our website at www.cbre.com. We will submit all candidates nominated by a stockholder pursuant to the procedures and requirements outlined in this “—Other Stockholder Proposals or Nominations for Presentation at the 2019 Annual Meeting” section to the Governance Committee for its review, and this submission may include an analysis of the candidate from our management. Any stockholder making a nomination in accordance with the foregoing process will be notified of the Governance Committee’s decision.

The Audit and Finance Committee of our Board appointed KPMG LLP as our independent registered public accounting firm to audit our consolidated financial statements for the fiscal year ending December 31, 2018. During 2017, KPMG LLP served as our independent accountant and reported on our consolidated financial statements for that year. KPMG LLP has been our independent auditor at all times since 2008.

The Audit and Finance Committee periodically considers whether to rotate our independent auditor in order to assure continuing auditor independence. The Board and the members of the Audit and Finance Committee believe that the continued retention of KPMG LLP as the company’s independent auditor in fiscal year 2018 is in the best interests of the company and its stockholders.

We expect that representatives of KPMG LLP will attend the Annual Meeting and will have the opportunity to make a

statement if they so desire and to respond to appropriate questions.

Although stockholder ratification is not required, the appointment of KPMG LLP is being submitted for ratification at the Annual Meeting with a view towards soliciting stockholders’ opinions, which the Audit and Finance Committee will take into consideration in future deliberations. If KPMG LLP’s selection is not ratified at the Annual Meeting, the Audit and Finance Committee will consider the engagement of other independent accountants. The Audit and Finance Committee may terminate KPMG LLP’s engagement as our independent accountant without the approval of our stockholders whenever the Audit and Finance Committee deems termination appropriate.

Audit Fees—Includes fees associated with the audit of our annual financial statements, review of our annual report on Form 10-K and quarterly reports on Form 10-Q, statutory audits, and consents and assistance with and review of registration statements filed with the SEC. In addition, audit fees include those fees related to KPMG LLP’s audit of the effectiveness of our internal controls over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act.

Audit-Related Fees—Includes fees associated with the audit of our employee benefit plans, accounting consultations

related to GAAP and the application of GAAP to proposed transactions. In addition, audit-related fees include those fees related to KPMG LLP’s audit of the effectiveness of our internal controls over client accounting.

Tax Fees—Includes fees associated with tax compliance at international locations, domestic and international tax advice and planning and assistance with tax audits and appeals.

The Audit and Finance Committee is responsible for overseeing and approving our independent auditor’s fees, and pre-approves all audit and permissible non-audit services provided by our independent auditor. These services may include audit services, audit-related services, tax services and other services. Pre-approval is generally provided for up to one year and any pre-approval is detailed as to the particular service or category of services and is generally subject to a specific budget. Our independent auditors and management

are required to periodically report to the Audit and Finance Committee regarding the extent of services provided by the independent auditor in accordance with this pre-approval process and the fees for the services performed to date. In certain one-off cases, the Audit and Finance Committee Chair (on behalf of the Audit and Finance Committee) may also pre-approve particular services, with that pre-approval subject to subsequent Audit and Finance Committee ratification.

The Audit and Finance Committee consists of five directors, each of whom is independent under NYSE rules and applicable securities laws. The Board has determined that each member of the Audit and Finance Committee is financially literate as required under NYSE rules. Our Board has also determined that each of Messrs. Feeny and Jenny, Ms. Reynolds and Dr. Tyson meets the qualifications of an

audit committee financial expert as described under “Corporate Governance—Board Meetings and Committees—Audit and Finance Committee” on page 19. The Audit and Finance Committee operates under a written charter adopted by the Board a copy of which is published in the Corporate Governance section of the Investor Relations page of our website at www.cbre.com.

The Audit and Finance Committee assists the Board in fulfilling its responsibilities to our stockholders with respect to our independent auditors, our corporate accounting and reporting practices, risk oversight and the quality and integrity of our financial statements and reports. The Audit and Finance Committee is directly responsible for overseeing the appointment, compensation, retention and oversight of the work of our independent auditor, and the Audit and Finance Committee and its chair oversee the selection of our independent auditor’s lead engagement partner. In addition, the Audit and Finance Committee reviews and considers all potential related-party and corporate-opportunity transactions involving us and our directors and executive officers, and periodically reviews our balance sheet management, borrowing and capital markets activities as well as our merger-and-acquisition and co-investment performance.

The Audit and Finance Committee discussed with our independent auditors the scope, extent and procedures for the fiscal 2017 audit. Following completion of the audit, the Audit and Finance Committee met with our independent auditors, with and without management present, to discuss the results of their examinations, the cooperation received by the auditors during the audit examination, their evaluation of our internal controls over financial reporting and the overall quality of our financial reporting.

Management is primarily responsible for our financial statements, reporting process and systems of internal controls. In ensuring that our management fulfilled that responsibility, the Audit and Finance Committee reviewed and discussed with management the audited financial statements in the Annual Report on Form 10-K for the fiscal year ended December 31, 2017. Discussion topics included the quality and acceptability of the accounting principles, the reasonableness of significant judgments, the clarity of disclosures in the financial statements and an assessment of the work of the independent auditors.

The independent auditors are responsible for expressing an opinion on the conformity of the audited financial statements with GAAP. The Audit and Finance Committee reviewed and discussed with the independent auditors their judgments as to the quality and acceptability of our accounting principles and such other matters as are required to be discussed by Public Company Accounting Oversight Board Auditing Standard No. 1301 “Communications with Audit Committees” and the Sarbanes-Oxley Act of 2002. In addition, the Audit and Finance Committee received from the independent auditors

written disclosures and a letter regarding their independence as required by applicable rules of the Public Company Accounting Oversight Board regarding the independent auditors’ communications with the Audit and Finance Committee, discussed with the independent auditors their independence from us and our management and considered the compatibility of non-audit services with the auditors’ independence.

Based on the reviews and discussions described above, the Audit and Finance Committee recommended to the Board (and the Board subsequently approved) the inclusion of the audited financial statements in the Annual Report on Form 10-K for the fiscal year ended December 31, 2017 for filing with the SEC.

In addition, the Audit and Finance Committee has appointed KPMG LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2018. The Board concurred with the selection of KPMG LLP. The Board has recommended to our stockholders that they ratify and approve the selection of KPMG LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2018.

In accordance with law, the Audit and Finance Committee is responsible for establishing procedures for the receipt, retention and treatment of complaints that we receive regarding accounting, internal accounting controls or auditing matters, including the confidential, anonymous submission of complaints by our employees received through established procedures of concerns regarding questionable accounting or auditing matters. The Audit and Finance Committee approved the establishment of an ethics and compliance program in 2004 and receives periodic reports from our Chief Ethics and Compliance Officer regarding that program.

Notwithstanding any statement in any of our filings with the SEC that might be deemed to incorporate part or all of any filings with the SEC by reference, including this Proxy Statement, the foregoing Report of the Audit and Finance Committee is not incorporated into any such filings.

Our Board is committed to excellence in governance and recognizes the interest of our stockholders in our executive compensation program. As a part of that commitment, and in accordance with SEC rules, we are asking you to approve, on an advisory basis, a resolution on the compensation of the named executive officers as reported in this Proxy Statement. This proposal, commonly known as a “say on pay” proposal, gives you the opportunity to endorse or not endorse our 2017 executive compensation program and policies for our named executive officers. The Board has adopted a policy providing for annual “say on pay” advisory votes. Accordingly, the next “say on pay” vote will occur at our annual meeting of stockholders in 2019.

In deciding how to vote on this proposal, our Board encourages you to review the “Compensation Discussion and Analysis” in this Proxy Statement beginning on page 31 for a detailed description of our executive compensation philosophy and programs.

This vote is not intended to address any specific item of compensation, but rather the overall compensation that was paid in 2017 to our named executive officers resulting from our compensation objectives, policies and practices as described in this Proxy Statement. Because your vote is advisory, it will not be binding upon the Board. However, the Board and the Compensation Committee value the opinions expressed by our stockholders and will review the voting results in connection with their ongoing evaluation of our executive compensation program.

We received strong support for our executive compensation from our stockholders at our 2017 annual meeting of stockholders, at which over 97% of the votes cast on the “say on pay” proposal were in favor of the 2016 compensation that we paid to our named executive officers. In addition, stockholders that we engaged with as part of our outreach

program generally reported that executive compensation was viewed as well-aligned with performance.

Our executive compensation program is designed to reinforce our corporate strategy and to attract and retain accomplished and high-performing executives and to motivate those executives to consistently achieve short- and long-term goals consistent with and in furtherance of our corporate strategy. To achieve this goal, we have designed an executive compensation program based on the following principles:

The text of the resolution in respect of Proposal 3 is as follows:

RESOLVED, that the compensation paid to our named executive officers for 2017 set forth in the Compensation Discussion and Analysis, the Summary Compensation Table and the related compensation tables and narrative in this Proxy Statement, as disclosed pursuant to Item 402 of Regulation S-K, is hereby approved on an advisory basis.

We achieved strong overall financial and operational performance in 2017 over 2016. Historically, our Board has set aggressive targets to achieve strategic growth and increase stockholder value consistent with stockholder expectations of growth in profits each year, and our 2017 operating plan assumed continued solid growth over 2016. In 2017, we outperformed our internal growth target on a global basis and for our Global Workplace Solutions business. As we describe in greater detail under the heading “Compensation Discussion and Analysis” beginning on page 31, our overall performance directly impacted a portion of the compensation of all of our named executive officers, and the performance of our Global Workplace Solutions business directly impacted a portion of the compensation for William F. Concannon (our Global Group President and CEO—Global Workplace Solutions).

Our executive compensation program is designed to reinforce our corporate strategy and to attract and retain accomplished and high-performing executives and to motivate those executives to consistently achieve short- and long-term goals consistent with and in furtherance of our corporate strategy. Our pay philosophy emphasizes pay-for-performance through significant variable compensation tied to accomplishments against financial metrics and strategic measures relative to targets and goals. Due to our solid overall financial and operational performance in 2017, and after giving effect to each executive’s strong performance on his respective strategic measures, the total direct cash compensation earned in respect of 2017 was above the target amounts established for our CEO and Messrs. Groch, Lafitte, Frese and Concannon.

Summarized on page 34 are the key components of our executive compensation program established and administered by the Board’s Compensation Committee (which we shall refer to in this CD&A as the “Committee”) with respect to our executive compensation program for the named executive officers for 2017.

As part of the review of target annual compensation, and after consultation with the Committee’s independent compensation consultant and consideration of market compensation data, in early 2017, the Committee approved increases to Messrs. Frese and Concannon’s annual base salary and increases in both the target annual performance award and annual long-term equity target for Messrs. Sulentic, Frese and Concannon. These increases reflect their superior performance as well as better alignment relative to their respective market peers and other CBRE global executives.

In reviewing executive compensation for 2017 as compared to prior years, it is important to keep the following in mind:
