PROXY STATEMENT

        This proxy is being used to permit all holders of the common shares of beneficial interest ("common shares") of Corporate Office Properties Trust (the "Company") to vote since many may be unable to attend the 2020 Annual Meeting of Shareholders (the "Annual Meeting") in person. Our Board of Trustees (the "Board") encourages you to read this document thoroughly and to take this opportunity to vote on the matters to be decided at the Annual Meeting. We will begin distribution and electronic availability of this proxy statement and proxy card on or about April 1, 2020.

        In accordance with the rules of the Securities and Exchange Commission (the "SEC"), instead of mailing a printed copy of our proxy materials to each shareholder of record or beneficial owner, we are furnishing our proxy materials (proxy statement for Annual Meeting, proxy card and 2019 Annual Report) by providing access to these materials on the Internet. Our shareholders will not receive printed copies of the proxy materials unless they request this form of delivery. Printed copies will be provided upon request at no charge.

        A Notice of Meeting and Internet Availability of Proxy Materials ("Notice of Internet Availability") will be mailed to our shareholders on or about April 1, 2020. We are providing the Notice of Internet Availability in lieu of mailing the printed proxy materials and are instructing our shareholders as to how they may: (1) access and review our proxy materials on the Internet; (2) submit their proxy; and (3) receive printed proxy materials. Shareholders may request to receive printed proxy materials by mail or electronically by e-mail on an ongoing basis by following the instructions in the Notice of Internet Availability. We believe that providing future proxy materials by e-mail will save us some of the costs associated with printing and delivering the materials and reduce the environmental impact of our annual meetings. A request to receive proxy materials in printed form by mail or by e-mail will remain in effect until such time as the shareholder elects to terminate it.

        Our mailing address is 6711 Columbia Gateway Drive, Suite 300, Columbia, Maryland 21046-2104 and our Internet address is www.copt.com. The information on our Internet site is not part of this proxy statement.

Who is entitled to vote at the Annual Meeting and how many votes do they have?

        Common shareholders of record at the close of business on March 12, 2020 may vote at the Annual Meeting. Each share has one vote. There were 112,179,163 common shares outstanding on March 4, 2020.

How do I vote?

        You must be present, or represented by proxy, at the Annual Meeting in order to vote your shares. Since many of our shareholders are unable to attend the Annual Meeting in person, we send the Notice of Internet Availability and, if requested, proxy cards to enable all of our shareholders to vote.

What is a proxy?

        A proxy is a person you appoint to vote on your behalf. If you vote by Internet, telephone or proxy card, your shares will be voted by the identified proxies.

        You can vote in one of three ways:

1.

By Internet.    To vote using the Internet, go to the website listed on your Notice of Internet Availability or proxy card. You will need to follow the instructions on that website.



2.

By telephone.    To vote by telephone, call the toll-free number listed on your Notice of Internet Availability or proxy card. You will need to follow the instructions and the prompts from the telephone voting system.



3.

By mail.    If you requested printed proxy materials and wish to vote by mail, simply mark, sign and date the proxy card and return it in the postage-paid envelope provided.

        If you vote by Internet or telephone, you should not return your proxy card.

        If you hold your shares through a broker, bank or other nominee, you will receive separate instructions from the nominee describing how to vote your shares.

How will my proxies vote my shares?

        Your proxies will vote according to your voting instructions. If you provide voting instructions but the instructions you provide do not indicate your vote on business matters, your proxies will vote as follows:

•

"FOR" each of the nominees for Trustee listed in Proposal 1;



•

"FOR" the ratification of the appointment of PricewaterhouseCoopers LLP as our Independent Auditor for the current fiscal year; and

3

Table of Contents

•

"FOR" approval, on an advisory basis, of the compensation of our named executive officers as disclosed in this proxy statement.

        We do not intend to bring any other matter for a vote at the Annual Meeting, and we do not know of anyone else who intends to do so. However, your proxies are authorized to vote on your behalf, in their discretion, on any other business that properly comes before the Annual Meeting.

How do I revoke my proxy?

        You may revoke your proxy at any time before your shares are voted at the Annual Meeting by:

•

Notifying our Vice President, General Counsel and Secretary, David L. Finch, in writing at our mailing address set forth on the first page of this proxy statement, that you are revoking your proxy;



•

Executing a later dated proxy card;



•

If previous instructions were given through the Internet or by telephone, by providing new instructions by the same means; or



•

Attending and voting by ballot at the Annual Meeting.

Who will count the votes?

        An officer of Corporate Office Properties Trust will act as the Inspector of Election and will count the votes.

What constitutes a quorum?

        As of March 4, 2020, Corporate Office Properties Trust had 112,179,163 common shares outstanding. A majority of the outstanding shares present or represented by proxy constitutes a quorum. If you complete the voting process by Internet or telephone or sign and return your proxy card, your shares will be counted in determining the presence of a quorum, even if you abstain or otherwise withhold your vote. If a quorum is not present at the Annual Meeting, the shareholders present in person or by proxy may adjourn the meeting to a date not more than 120 days after March 12, 2020 until a quorum is present.

What vote is required to elect Trustees?

        Our Bylaws provide that, in an uncontested election, a nominee for Trustee is elected only if such nominee receives the affirmative vote of a majority of the total votes cast for and against such nominee. The majority voting standard would not apply in contested elections.

        The majority voting standard will apply to the election of Trustees at the Annual Meeting. Accordingly, a nominee for Trustee will be elected if such nominee receives the affirmative vote of a majority of the total votes cast for and against such nominee. Broker non-votes, if any, and abstentions will not be treated as votes cast for or against the election of a nominee for Trustee.

        Our Board of Trustees has also adopted a resignation policy which is included in our Bylaws, under which a Trustee nominated for re-election who fails to receive the required number of votes for re-election will tender his or her resignation to our Board of Trustees for its consideration. The Nominating and Corporate Governance Committee will act on an expedited basis to determine whether it is advisable to accept the Trustee's resignation and will submit the recommendation for prompt consideration by our Board. Our Board will act on the tendered resignation within 90 days following certification of the shareholder vote and will promptly and publicly disclose its decision. The Trustee whose resignation is under consideration will abstain from participating in any decision regarding his or

her resignation. If the resignation is not accepted, the Trustee will continue to serve until the next annual meeting of shareholders and until the Trustee's successor is duly elected and qualified or until the Trustee's earlier resignation or removal. The Nominating and Corporate Governance Committee and our Board may consider any factors they deem relevant in deciding whether to accept a Trustee's resignation.

What vote is required on other matters?

        In general, a majority of the votes cast at a meeting of shareholders is required to approve any other matter unless a greater vote is required by law or by the Company's Declaration of Trust. With respect to the other Proposals to be voted on at the Annual Meeting, the required vote to approve each of Proposal 2 and 3 is a majority of the votes cast on each such proposal. See "How Will My Vote Be Counted" for more detail on the treatment of abstentions and "broker non-votes" on Proposals 2 and 3.

What is a broker non-vote?

        A "broker non-vote" occurs when a nominee (such as a custodian or bank) holding shares for a beneficial owner returns a signed proxy but does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that item and has not received instructions from the beneficial owner.

How will my vote be counted?

        With respect to Proposal 1, the election of Trustees, votes may be cast for or against each nominee. You may also abstain with respect to each nominee. Because abstentions and broker non-votes are not considered votes cast, they will have no effect on the outcome of the vote on election of Trustees.

        With respect to each of Proposals 2 and 3, you may abstain, and your abstention will have no effect on the outcome of the vote, because no vote will have been cast with respect to your shares. Broker non-votes will have no effect on the outcome of Proposals 2 and 3, because no vote will have been cast with respect to your shares.

What percentage of our common shares do the Trustees and executive officers own?

        Our Trustees and executive officers owned in the aggregate less than 1.0% of our outstanding common shares as of March 4, 2020 (see the discussion under the heading "Share Ownership of our Trustees, Executive Officers and 5% Beneficial Owners" for more details).

Who is soliciting my proxy, how is it being solicited and who pays the cost?

        Our Board is soliciting your proxy. The solicitation process is being conducted primarily by mail. However, proxies may also be solicited in person, by telephone or facsimile. Broadridge Financial Solutions, Inc., our proxy distribution and tabulation agent, will be assisting us for a fee of approximately $38,000 plus out-of-pocket expenses. We pay any cost incurred for soliciting proxies and also reimburse stockbrokers and other custodians, nominees and fiduciaries for their reasonable out-of-pocket expenses for forwarding proxy and solicitation material to the owners of common shares.

These requirements do not affect the deadline for submitting shareholder proposals for inclusion in the proxy statement for the 2021 Annual Meeting (discussed in the question and answer below), nor do they apply to questions a shareholder may wish to ask at that meeting.

When are shareholder proposals intended to be included in the proxy statement for the 2021 Annual Meeting due?

        Shareholders who wish to include proposals in the proxy statement must submit such proposals in accordance with regulations adopted by the SEC. Shareholder proposals for the 2021 Annual Meeting must be submitted in writing by December 1, 2020. In addition, shareholders may wish to have a proposal presented at the 2021 Annual Meeting but not to have such proposal included in the proxy statement for the 2021 Annual Meeting. Pursuant to our Bylaws, notice of any such proposal must be received by us between February 21, 2021, and no later than March 22, 2021. If it is not received during this period, such proposal shall be deemed "untimely" for purposes of Rule 14a-4(c) under the Exchange Act, and, therefore, the proxies will have the right to exercise discretionary voting authority with respect to such proposal.

        Any shareholder proposals must be submitted to David L. Finch, Vice President, General Counsel and Secretary, at our mailing address set forth on the front page of this proxy statement. You should submit any proposal by a method that permits you to prove the date of delivery to us.

How can interested parties send communications to the Board?

        Any interested parties who wish to communicate with the members of our Board may communicate with the independent Trustees, the Chairman of the Board or the chairperson of any of the committees of the Board by e-mail or regular mail. Communications by e-mail should be sent to david.finch@copt.com. Communications by regular mail should be sent to the attention of: the Chairman of the Board; Chairperson, Audit Committee; Chairperson, Compensation Committee; Chairperson, Nominating and Corporate Governance Committee; Chairperson, Investment Committee; or, for communications intended for the independent Trustees as a group, to the Independent Trustees. In each case, the communication should be sent care of David L. Finch, Vice President, General Counsel and Secretary, at our mailing address set forth on the front page of this proxy statement.

        All communications received in accordance with this process will be reviewed by management to determine whether the communication requires immediate action. Management will transmit all communications received, or a summary of such communications, to the appropriate Trustee or Trustees. However, management reserves the right to disregard any communication that it determines is unduly hostile, threatening, illegal, does not reasonably relate to us or our business or is similarly inappropriate, and has the authority to discard or disregard any inappropriate communications or to take other appropriate actions with respect to any such inappropriate communications.

        Our Board has adopted Corporate Governance Guidelines that set forth our policies concerning overall governance practices. These Guidelines can be found in the Investor Relations section of our Internet website in the subsection entitled "Corporate Governance." Our Internet website address is www.copt.com.

Proposal 1—Election of Trustees

        Our Bylaws provide for the annual election of Trustees at the Annual Meeting of Shareholders. Our Board, at the recommendation of its Nominating and Corporate Governance Committee, has nominated eight of our current Trustees for re-election at the Annual Meeting. Each nominee has agreed to serve a one-year term. If any nominee is unable to stand for election, the Board may provide for a lesser number of Trustees or designate a substitute. In the latter event, shares represented by proxies will be voted for a substitute nominee.

        The following biographies set forth certain information with respect to the nominees for election as Trustees, all of whom currently serve as Trustees who have been nominated by the Board and are standing for re-election. These descriptions include, in the second paragraph of each, the specific experience, qualifications, attributes and skills that led the Board to nominate each of them for re-election.

        Thomas F. Brady, 70, has been Chairman of our Board since May 2013 and has been a member of our Board since January 2002. Since 2009, he has advised Opower, Inc. and served as Chairman of the Opower Advisory Board until 2016.

        Mr. Brady's extensive career in key financial and strategic executive positions at a larger public company, and experiences with privately-owned, venture capital funded start-up companies, qualifies him to lead our Board and assess our strategic initiatives, both qualitatively and quantitatively. Mr. Brady's utility operations experience and significant civic involvement also complement and enhance the perspectives which he brings to his role as Chairman of the Board.

        Stephen E. Budorick, 59, was appointed President and Chief Executive Officer on May 12, 2016. On the same date he was appointed to the COPT Board of Trustees.

        Mr. Budorick's experience as the President and Chief Executive Officer of the Company and his prior experience as the Company's Chief Operating Officer, as well as his depth of both operational and financial expertise, make him highly qualified to serve as a valued member of our Board. In his role as Chief Executive Officer, Mr. Budorick is a critical link between the Board and management. His experience at initiating and implementing strategic initiatives and continued engagement in the commercial real estate community are valuable assets to the Board.

In addition, Mr. Hawkins' existing public company board service enhances the insights he brings as a Board member.

Our Board of Trustees

How do we determine whether our Trustees are independent?

        We believe that for our Board to effectively serve in its capacity, it is important, and the New York Stock Exchange ("NYSE") mandates, that at least a majority of our Trustees be independent as defined by the applicable rules of the NYSE. Therefore, we require that a substantial majority of the Board be independent, as so defined. No Trustee will be considered independent unless the Board affirmatively determines that the Trustee has no material relationship with the Company (directly or as a partner, shareholder or officer of an organization that has a relationship with the Company). A Trustee will not be deemed independent if: (1) the Trustee is, or within the last three years, has been, employed by the Company or a member of his/her immediate family is, or within the last three years has been, an executive officer of the Company; (2) the Trustee or a member of his/her immediate family receives, or during any 12-month period within the last three years received, more than $120,000 in direct compensation from the Company (other than Trustee and committee fees and pension or other forms of deferred compensation for prior service, provided such compensation is not contingent in any way

on continued service); (3) the Trustee is a current partner or employee of the Company's internal auditors or outside independent registered public accounting firm serving as the Company's auditors, or a member of the Trustee's immediate family is a current partner of such auditors or firm, or is a current employee of such auditors or such firm and personally works on the Company's audit, or the Trustee or a member of the Trustee's immediate family was within the last three years a partner or employee of such auditors or firm and personally worked on the Company's audit during that time; (4) the Trustee or a member of his/her immediate family is, or within the last three years has been, employed as an executive officer of another entity of which any of the Company's present executive officers at the time serves or served on that other entity's compensation committee; (5) the Trustee is a current employee, or a member of his/her immediate family is a current executive officer, of another company that has made payments to, or received payments from, the Company for property or services in an amount which, in any of the last three fiscal years, exceeded the greater of $1 million or 2% of such other company's consolidated gross revenues; or (6) the Trustee is a current executive officer or compensated employee, or an immediate family member of the Trustee is a current executive officer, of a charitable organization to which the Company has made donations in an amount which, in any of the last three fiscal years, exceeded the greater of $1 million or 2% of such charitable organization's donations.

Are our Trustees independent of Corporate Office Properties Trust?

        The Board has determined that each of our nominees for Trustee meets the independence guidelines described above except for Mr. Budorick, our President and Chief Executive Officer.

What is the leadership structure of our Board of Trustees?

        Our governance documents provide the Board with flexibility to select the appropriate leadership structure for the Company. In making leadership structure determinations, the Board considers many factors, including the specific needs of our business and what is in the best interests of the Company's shareholders. Our current leadership structure is comprised of an independent Chairman of the Board separate from the Chief Executive Officer. Among other things, the Board believes that having an independent Chairman enhances the ability of non-management Trustees to raise issues and concerns for Board consideration without immediately involving management and has determined that this structure is the most appropriate structure at this time.

        Under our Bylaws, the Chairman of the Board shall preside over the meetings of the Board and of the shareholders at which he or she shall be present and shall in general oversee all of the business and affairs of the Company. In the absence of the Chairman, the Chief Executive Officer shall preside over the meetings of the Trustees and of the shareholders at which he shall be present. The Chairman shall perform such other duties as may be assigned by the Trustees. The Chief Executive Officer shall have responsibility for implementation of the policies of the Company, as determined by the Board, and for the administration of the business affairs of the Company.

What is our policy regarding Trustee attendance at regularly scheduled meetings of the Board and the annual meeting of shareholders?

        The Board holds a minimum of four regularly scheduled meetings per year, including the meeting of the Board held in conjunction with our annual meeting of shareholders. Trustees are expected to attend all regularly scheduled meetings and to have reviewed, prior to the meetings, all written meeting materials distributed to them in advance. Trustees are expected to be physically present at all regularly scheduled meetings, and a Trustee who is unable to attend a meeting is expected to notify the Chairman of the Board in advance of such meeting. If a Trustee attends a regularly scheduled meeting by telephone for the entire meeting, such Trustee shall be deemed to have attended the meeting for the purposes of determining whether a quorum exists and for voting purposes. A Trustee may not send a

11

Table of Contents

representative with a proxy to vote on his or her behalf if such Trustee is not able to attend a scheduled meeting.

        Trustees are expected to be present at our annual meeting of shareholders. All but one of our Trustees who were nominated for re-election at the time of the 2019 Annual Meeting of Shareholders were in attendance at the meeting; the non-attending Trustee missed the meeting due to illness.

What is our policy regarding meetings of non-management Trustees?

        The non-management Trustees meet in executive session at each of the regularly scheduled meetings. The Chairman of the Board presides at the executive sessions. The non-management Trustees may meet in executive session at any time to consider issues that they deem important to address without management present.

How are the Trustees compensated?

•

Employee Trustees receive no compensation, other than their compensation as an employee, for serving on the Board or its committees.



•

Non-employee Trustees received the following:



o

Fees, paid in cash, set forth below:

The fees set forth above did not change from 2018. Our Trustee compensation is reviewed against market and our peers bi-annually in consultation with our external compensation consultant.

o

Reimbursement for out-of-pocket expenses, such as travel and lodging costs incurred in connection with meeting attendance; and



o

Annual grants of restricted shares ("RSs"), restricted share units or time-based profit interest units in COPLP in an award value of not more than $95,000, calculated utilizing the 15-day trailing average share price as of the grant date. Forfeiture restrictions for the aforementioned award types lapse on the first anniversary of the grant date, provided that the Trustee remains in his or her position. With respect to RSs and restricted share units, the resulting common shares are issued either on the first anniversary of the grant date for RSs or on a later date selected by the Trustee for restricted share units. Holders of RSs and restricted share units are entitled to receive dividends on such shares. Prior to vesting, the time-based profit interest units carry substantially the same rights to distributions as non-profit interest unit common units but carry no redemption rights. Holders of RSs can cast votes for such shares, while holders of the other award types cannot cast votes for such units.

        The table below sets forth the total amounts of compensation earned by our non-employee Trustees during 2019:

What are the committees of our Board?

        The Board has four committees: (1) the Audit Committee; (2) the Compensation Committee; (3) the Investment Committee; and (4) the Nominating and Corporate Governance Committee. Descriptions of these committees are set forth below:

•

The Audit Committee oversees the following for the Company:



o

integrity of financial statements and other financial information provided to shareholders and the investment community;



o

compliance with certain legal and financial regulatory requirements and ethical behavior;



o

retention of our Independent Auditor, including oversight of its performance, qualifications and independence, approval of the scope of the audit and non-audit services and associated fees and input into the selection of the lead engagement partner with each rotation;



o

accounting and financial reporting processes, internal control systems and the internal audit function; and



o

risk management activities.

The Committee also provides an avenue for communication among our Independent Auditor, internal auditors, management and the Board.

•

The Compensation Committee's primary responsibilities are set forth below:



o

establish and periodically review the Company's compensation philosophy and the adequacy of compensation plans and programs for executive officers and to make recommendations to the Board with respect to such compensation;



o

establish compensation arrangements and incentive goals (Company financial measures, business metrics and individual goals) for executive officers and to administer such compensation plans and programs;

13

Table of Contents

o

review and approve goals and objectives relevant to the Chief Executive Officer's compensation, evaluate the CEO's performance in light of those goals and objectives and, either as a Committee or together with the other independent Trustees (as directed by the Board), recommend to the Board for approval the CEO's compensation level based on this evaluation;



o

review the performance of all other executive officers and award incentive compensation and adjust compensation arrangements as appropriate based upon performance;



o

review and consider risks relating to the Company's compensation policies; and



o

review compensation arrangements for Trustees and make appropriate recommendations to the Board for approval.



•

The Board has delegated to the Investment Committee the authority to approve various matters (acquisitions, dispositions, development/redevelopment projects, financings, joint ventures, equity issuances and other investments) when the matters are below certain threshold amounts. However, any matters that are greater than $75 million require the approval of the full Board.



•

The Nominating and Corporate Governance Committee serves the following purposes:



o

recommend to the Board the structure and operations of the Board;



o

identify individuals qualified to serve as Trustees and recommend that the Board select the Trustee nominees identified by the Committee for election at the next annual meeting of shareholders;



o

recommend to the Board the responsibilities of each Board committee, the structure and operation of each committee and the Trustee nominees for assignment to each committee, including the recommendation of the chair for each Board committee;



o

oversee the Board's annual evaluation of its performance and the performance of all Board committees;



o

develop and recommend to the Board for adoption a set of Corporate Governance Guidelines applicable to the Company and periodically reviews the same; and



o

review and monitor management development and succession plans and activities.

All members of the Audit, Nominating and Corporate Governance and Compensation Committees are independent Trustees and meet the applicable requirements for committee membership under the NYSE rules. The practices of the Audit, Nominating and Corporate Governance and Compensation Committees are outlined in their respective charters, which are available on our Internet website in the subsection entitled "Corporate Governance" or in print to any shareholder upon request. To the extent modifications are made to the charters, such modifications will be reflected on our Internet website.

Table of Contents

        The committees on which Trustees served and the number of meetings held during 2019 are set forth below:

        During 2019, the Board held four quarterly meetings. Each incumbent Trustee in 2019 attended at least 75% of the aggregate of the meetings of the Board and meetings held by all committees on which such Trustee served.

How are Trustees evaluated?

        The Board recognizes that a robust and constructive evaluation process is an essential part of good corporate governance and board effectiveness. The evaluation processes utilized by the Board are designed and implemented under the direction of the Nominating and Corporate Governance Committee and aim to assess Board and committee effectiveness as well as individual Trustee performance and contribution levels. The Nominating and Corporate Governance Committee and full Board consider the results of the annual evaluations in connection with their review of Trustee nominees to ensure the Board continues to operate effectively. Each year our Trustees complete anonymous governance questionnaires and self-assessments. These questionnaires and assessments facilitate a candid assessment of: (i) the Board's performance in areas such as business strategy, risk oversight, talent development and succession planning and corporate governance; (ii) the Board's structure, composition and culture; and (iii) the mix of skills, qualifications and experiences of our Trustees.

How are our Trustees nominated?

        The Nominating and Corporate Governance Committee of the Board is responsible for recommending nominations to the Board and shareholders. In arriving at nominations, the Nominating and Corporate Governance Committee reviews with the Board the size, function, and needs of the Board and, in doing so, takes into account the principle that the Board as a whole should be competent in the following areas: (1) industry knowledge; (2) accounting and finance; (3) business judgment; (4) management and communication skills; (5) leadership; (6) public real estate investment trusts ("REITs") and commercial real estate business; (7) business strategy; (8) crisis management; (9) corporate governance; and (10) risk management. The Board also seeks members from diverse backgrounds. Trustees should have experience in positions with a high degree of responsibility, be leaders in the companies or institutions with which they are or were affiliated, and be selected based upon contributions that they can make to the Company. In determining whether to recommend a Trustee for re-election, the Nominating and Corporate Governance Committee also considers the Trustee's past attendance at meetings and participation in, and contributions to, the activities of the Board and its committees.

15

Table of Contents

        Our Board does not have an explicit diversity policy. Nevertheless, diversity of race, ethnicity, gender, age, cultural background and professional experience is considered in evaluating candidates for nomination. The Board believes that its members should exhibit integrity and ethical behavior, and that they should collectively represent a broad spectrum of experience and expertise. Diversity is important because a variety of points of view contribute to a more effective decision-making process.

        The Nominating and Corporate Governance Committee has a policy regarding consideration of shareholder recommendations for Trustee nominees, which is set forth below:

        The Committee considers nominees recommended by the Company's common shareholders using the same criteria it employs in identifying its own nominees. Any shareholder wishing to make a recommendation should send the following information to the Chairman of the Nominating and Corporate Governance Committee, care of David L. Finch, Vice President, General Counsel and Secretary, at our mailing address set forth on the first page of this proxy statement, no later than the date that is 120 days prior to the one-year anniversary of the date of the mailing of the Company's proxy statement for its most recent annual meeting of shareholders:

•

the name of the candidate and the information about the individual that would be required to be included in a proxy statement under the rules of the SEC;



•

information about the relationship between the candidate and the nominating shareholder;



•

the consent of the candidate to serve as a Trustee;



•

proof of the number of shares of the Company's common shares that the nominating shareholder owns and the length of time the shares have been owned; and



•

a separate statement of the candidate's qualifications relating to the Board's membership criteria.

What is the Board's approach to risk oversight?

        The Board plays an important role in the risk oversight of the Company. While the Board and its Committees rely on management to bring significant matters to its attention, the Board establishes and monitors the Company's risk tolerance and oversees its risk management activities primarily by:

•

approving annually the strategic direction of the Company;



•

maintaining for itself and its committees direct decision-making authority with respect to matters with significant inherent risks, including material acquisition, disposition, development and financing activities and the appointment, retention and compensation of executive officers;



•

reviewing and discussing regular periodic reports relating to the performance of the Company and enterprise risk assessments relating to the achievement of its objectives;



•

approving the Company's annual budget and capital plan; and



•

overseeing specific areas of the Company's business by the Compensation, Audit, Investment and Nominating and Corporate Governance Committees.

        Pursuant to its charter, the Audit Committee is responsible for the review of the Company's risk assessment and management activities, including the Company's enterprise risk management ("ERM") assessment. The Committee discharges these responsibilities by reviewing and discussing with management, the Company's internal audit and information technology functions and our Independent Auditor any significant risks or exposures faced by the Company, the steps taken to identify, minimize, monitor or control such risks or exposures and the Company's underlying policies with respect to risk assessment and risk management. The Company's management, including those from the Company's information technology function, reports quarterly to the Audit Committee with respect to

16

Table of Contents

management's assessment of the Company's cybersecurity and information security risks and the actions taken by the Company to manage and/or mitigate such risks. Consistent with NYSE Rules, the Audit Committee also provides oversight with respect to risk assessment and risk management, particularly regarding the activities of the Company's internal audit function and integrity of the Company's financial statements and internal controls over financial reporting. The Company's internal audit function reports to the Audit Committee regarding such activities on an ongoing basis, including at all in-person and most telephonic meetings of the Audit Committee. The Board is informed regarding these risk oversight activities at the quarterly meetings of the Board.

Our Executive Officers

        Below is information with respect to our executive officers (in addition to Stephen E. Budorick, the Company's President and CEO) (sometimes referred to herein as our "executive officers" or "executives").

        Paul R. Adkins, 61, had been our Executive Vice President and Chief Operating Officer since November 2016. Effective March 16, 2020, Mr. Adkins resigned from his position as Executive Vice President and Chief Operating Officer of the Company. During his tenure with the Company, he oversaw the Company's leasing, asset management, property management, government services and commercial development, as well as the development and execution of strategies to expand investment opportunities, predominately regarding new development at our existing Defense/IT locations. From 2011 until joining the Company, Mr. Adkins served as Principal at The JBG Companies, a then privately-owned real estate investment and management firm at which he was responsible for large tenant and development leasing. Before his tenure at The JBG Companies, he was Executive Vice President and Managing Director of the Washington, DC region for Grubb & Ellis Company from 2010 to 2011. Mr. Adkins also served 21 years at CarrAmerica Realty Corporation (formerly NYSE: CRE) from 1982 to 2003 in leasing, acquisitions, and private equity.

        Anthony Mifsud, 55, has been our Executive Vice President & Chief Financial Officer since February 2015, after serving as Senior Vice President, Finance and Treasurer since January 2011 and having joined the Company in 2007 as Vice President, Financial Planning & Analysis. Prior to joining the Company, Mr. Mifsud served as Senior Vice President & Treasurer for Municipal Mortgage & Equity, LLC (MMA) and prior to joining MMA, was Vice President, Financial Management at Enterprise Social Investment Corporation. From 1990-2005, Mr. Mifsud held various accounting and corporate finance positions at The Rouse Company (formerly NYSE: RSE), culminating as Vice President, Finance from 1999-2005. Prior to that time, Mr. Mifsud practiced as a CPA and auditor at KPMG Peat Marwick.

Share Ownership of our Trustees,
Executive Officers and 5% Beneficial Owners

        The following table shows certain information as of March 4, 2020 (unless otherwise noted) regarding the beneficial ownership of our common shares by each Trustee, each nominee for election as Trustee, each executive officer, all Trustees and executive officers as a group and each person known to us to be the beneficial owner of more than 5% of our outstanding common shares. Beneficial ownership is determined in accordance with the rules of the SEC and means sole or shared voting or investment power with respect to securities. Each party named in the table below has sole voting and

17

Table of Contents

investment power with respect to the securities listed opposite such party's name, except as otherwise noted.

18

Table of Contents

Delinquent Section 16(a) Reports

        The rules of the SEC require that we disclose late filings of initial reports of share ownership and reports of changes in share ownership by our Trustees, officers and greater than 10% shareholders. Our Trustees, officers and greater than 10% shareholders are required by those rules to furnish us with copies of the reports of share ownership (and changes in share ownership) they file with the SEC. Based solely on our review of the copies of such reports received by us and other information provided by these parties, we believe that during 2019, our Trustees, officers and greater than 10% shareholders filed all required reports on a timely basis, except for two Form 4 filings relating to the purchase of a total of 683 shares through a dividend reinvestment plan by Mr. Kesler on January 16, 2019 and April 16, 2019 that were filed late.

Code of Ethics; Review and Approval of Related Party Transactions

        The Company has a Code of Business Conduct and Ethics for all employees and Trustees and a Code of Ethics for Financial Officers. These codes of ethics documents are available in the Investor Relations section of the Company's Internet website in the subsection entitled "Corporate Governance." The Company's Internet website address is www.copt.com. We will make available on our Internet website any future amendments or waivers to our Code of Business Conduct and Ethics and Code of Ethics for Financial Officers within four business days after any such amendments are adopted or waivers are granted. In addition, shareholders may request a copy of these codes of ethics documents, free of charge, by making this request in writing to our Vice President, Investor Relations at ir@copt.com or at our mailing address.

        Our Code of Business Conduct and Ethics mandates that the Audit Committee must review and approve any "related party transaction," as defined by relevant SEC rules (generally, transactions involving amounts exceeding $120,000 in which a related person has a direct or indirect material interest). In considering the transaction, the Audit Committee will consider all relevant factors, including, among others, our business rationale for entering into the transaction, any potential alternatives to entering into the transaction, whether the transaction is on terms that would be

19

Table of Contents

comparable to those available to third parties and the overall fairness of the transaction to the Company.

        In general, either management or the affected Trustee or executive officer will bring the matter to the attention of either the chairman of the Audit Committee or our Vice President, Secretary and General Counsel. If a member of the Audit Committee is involved in the transaction, he/she will be recused from all discussions and decisions about the transaction. The transaction must be approved in advance whenever practicable, and if not practicable, must be ratified as promptly as practicable.

Company's Commitment to Environmental and Social Responsibility

        We remain committed to environmentally and socially responsible investment that furthers the Company's goal to create value for its shareholders. Since 2003, we have been constructing buildings to the Leadership in Energy and Environmental Design ("LEED") Silver minimum. Further, the environmental, social, and governance ("ESG") practices engaged in by the Company constitute our sustainability platform and have informed and shaped our corporate culture for over a decade. As outlined in our Sustainability Report and noted in our 2019 Annual Report on Form 10-K, we invest in energy systems and equipment that reduce our energy consumption and operating costs. A copy of our most recent Sustainability Report can be found on the Investor Relations section of the Company's Internet website. Since 2010, we have embraced the LEED Existing Building: Operations and Maintenance ("LEEDEBOM") prerequisites, including green cleaning, recycling, ENERGY STAR, no smoking and other operations and maintenance policies to ensure our tenants and employees work in healthy environments. In 2014, we committed to annually participating in the Global Real Estate Sustainability Benchmark ("GRESB") survey and have participated in the survey every year since. The 2015 GRESB survey was our first submittal, and we earned a "Green Star" rating, the highest quadrant of achievement for each year from 2015 through 2018. In 2016, we published our first sustainability report in accordance with Global Reporting Initiative ("GRI") content and formatting. Early in 2018, our senior management team adopted a Corporate Sustainability Policy. Our sustainability objective is to balance the tactics outlined in our ESG Pledge, known by the acronym "RITE," with our fiduciary responsibility to our shareholders. Our Company pledges to sustainably develop and operate our portfolio to create healthier work environments and reduce consumption of resources. Our tactics for achieving our pledge are to Reduce, Innovate, Teach and Engage as part of our daily responsibilities. By following the "RITE" principles, we believe that we optimize our property operations and add value for all stakeholders. We also employ best practices in corporate governance, and robust community outreach programs, such as the Company's Donate 8, a program that encourages every employee to take one paid workday each year to volunteer with a non-profit organization in his or her community.

Report of the Audit Committee

        The Audit Committee of our Board is comprised of the four Trustees named below. Each of the Trustees meets the independence and experience requirements of the NYSE and satisfies the SEC's additional independence requirements for members of audit committees. The Board has determined that David M. Jacobstein, Steven D. Kesler and Lisa G. Trimberger each qualify as an "audit committee financial expert" as defined by the SEC. The Audit Committee adopted and the Board approved, a charter outlining the Audit Committee's practices. A copy of the charter is publicly available in the investor relations section of the Company's Internet website in the subsection entitled "Corporate Governance." The Audit Committee's charter is also available in print to any shareholder upon request. To the extent modifications are made to the Audit Committee's charter, such modifications will be reflected in the copy of the charter maintained on the Company's Internet website.

        Management is responsible for the Company's financial statements, financial reporting process, internal control over financial reporting, compliance with legal and regulatory requirements and ethical

20

Table of Contents

behavior. Our Independent Auditor is responsible for expressing opinions on the conformity of the Company's consolidated financial statements with generally accepted accounting principles, the fairness of the presentation of the Company's financial statement schedules and the effectiveness of the Company's internal control over financial reporting in accordance with the Public Company Accounting Oversight Board ("PCAOB"). The Company's internal audit function is responsible for, among other things, helping to evaluate and improve the effectiveness of risk management, control and governance processes, and identifying opportunities to assist in improving the Company's operations. The role of the Audit Committee is to oversee these activities.

        Management completed its evaluation of the Company's system of internal control over financial reporting pursuant to the requirements set forth in Section 404 of the Sarbanes-Oxley Act of 2002 and related regulations. The Audit Committee was kept apprised of the progress of the evaluation and provided oversight during the process. In connection with this oversight, the Committee received periodic updates provided by management and the internal audit function at each regularly scheduled Committee meeting. At the conclusion of the process, management concluded that the Company's internal control over financial reporting was effective as of December 31, 2019 and reported its conclusion to the Audit Committee. The Committee reviewed Management's Report on Internal Control over Financial Reporting contained in the Company's and the Operating Partnership's Annual Report on Form 10-K for the year ended December 31, 2019 filed with the SEC, as well as the Independent Auditor's Report of Independent Registered Public Accounting Firm included in the Company's and the Operating Partnership's Annual Report on Form 10-K. The Report of Independent Registered Public Accounting Firm related to the audit of: (1) the consolidated financial statements and financial statement schedule included in the Annual Report on Form 10-K; and (2) the effectiveness of internal control over financial reporting. The Committee continues to oversee the Company's efforts related to its internal control over financial reporting and management's preparations for the evaluation in 2020.

        The Audit Committee met with the Company's accounting and financial management team, the internal audit function and the Independent Auditor to review the Company's annual and quarterly periodic filings containing consolidated financial statements prior to the Company's submission of such filings to the SEC. In addition, the Audit Committee met with the internal audit function and with the Independent Auditor, without the presence of management, to discuss their respective audits and projects.

        Management represented to the Audit Committee that the Company's and the Operating Partnership's consolidated financial statements for the year ended December 31, 2019 were prepared in accordance with generally accepted accounting principles. The Audit Committee discussed with the Independent Auditor the matters required to be discussed under Statement on Auditing Standards No. 16, as amended, which addresses communication between audit committees and independent registered public accounting firms. The Audit Committee received from the Independent Auditor the written disclosures and letter required by PCAOB Rule 3526, which addresses independence discussions between auditors and audit committees. The Audit Committee also held discussions with the Independent Auditor regarding its independence from the Company and its management and considered whether Independent Auditor's provision of audit and non-audit services provided to the Company during 2019 was compatible with maintaining the firm's independence.

        The Audit Committee has an established practice of requiring pre-approval of all audit and permissible non-audit services and associated fees provided by the Independent Auditor. The Audit Committee must consider whether the services it is approving impair the Independent Auditor's independence. All services were approved by the Audit Committee prior to the services being rendered.

        In determining whether to reappoint PricewaterhouseCoopers LLP ("PwC") as the Company's Independent Auditor, the Audit Committee took into account a number of factors, including: PwC's

21

Table of Contents

independence and objectivity; PwC's capability and expertise in handling the Company's industry, including the expertise and capability of the lead engagement partner; historic and recent performance, including the extent and quality of PwC's communications with the Audit Committee; the results of management and Audit Committee surveys of PwC's overall performance; data related to audit quality and performance, including recent PCAOB inspection reports on the firm; the appropriateness of PwC's fees, both on an absolute basis and as compared with its peers; and the length of time that PwC has been engaged. In addition to the foregoing, due to the lead engagement partner rotation requirements under the rules of the PCAOB, during 2018, the Audit Committee participated with management and PwC in the process to select the lead engagement partner to succeed the incumbent.

        In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board that the Company's and the Operating Partnership's audited consolidated financial statements for the year ended December 31, 2019 be included in the Company's and the Operating Partnership's Annual Report on Form 10-K for the year ended December 31, 2019 for filing with the SEC. This report is provided by the following independent Trustees, who constitute the Audit Committee.

        The Report of the Audit Committee shall not be deemed incorporated by reference by any general statement that incorporates by reference any portion of this proxy statement into any filing under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, except to the extent that the Company specifically incorporates this information by reference, and shall not otherwise be deemed filed under such acts.

Independent Registered Public Accounting Firm

        PwC served as our Independent Auditor for the years ended December 31, 2019 and 2018. PwC also provided us with other auditing and advisory services. We are cognizant of the need for PwC to maintain its independence and objectivity in order to effectively serve in its role as our Independent Auditor. As a result, our Audit Committee restricted the services for which PwC can be engaged to those services that could not impair or appear to impair PwC's independence and objectivity. In making this determination, the Audit Committee contemplates the nature of the services, the benefits that PwC performing such services brings both to the services and to its audits and PwC's proposed cost for providing such services. The Audit Committee believes PwC's tenure as the Company's Independent Auditor has been and remains a benefit to the Company. In 2015, the Company issued a request for proposals for auditing services and reviewed the responses from several reputable accounting firms. After evaluating the responses and interviewing certain of the accounting firms, the Audit Committee determined that it was in the best interest of the Company and its shareholders to continue to engage PwC. Due to the audit partner rotation requirements under the rules of the PCAOB, every five years the PwC lead engagement partner serving the Company rotates, which further ensures PwC's objectivity and independence. As such, as required, the lead engagement partner rotation occurred in 2019 following a selection and interview process during 2018 in which the Audit Committee participated with management.

        The Audit Committee has procedures in place regarding the pre-approval of all services provided by PwC. Specifically, management contacts the Audit Committee Chair regarding the potential need for a service from PwC. PwC then provides an engagement letter to management pertaining to the service,

22

Table of Contents

which management reviews for the service description and proposed fee. Once management agrees with the engagement letter, it forwards the engagement letter to the Audit Committee Chair. The Audit Committee Chair then reviews the engagement letter for the criteria described in the previous paragraph and if, based on such review, he approves of the terms of the engagement letter, he forwards the letter to the other Audit Committee members requesting that they respond within a certain period of time should they not approve of the engagement letter. The Audit Committee has delegated pre-approval authority to the Chair for certain audit-related services. All fees paid to PwC in 2019 were approved by the Audit Committee in accordance with this policy.

        For the years ended December 31, 2019 and 2018, we incurred the approximate fees and expenses set forth below with PwC:

None of the fees reflected above were approved by the Audit Committee pursuant to the "de-minimis exception" in Rule 2-01 of Regulation S-X.

        We expect that a representative of PwC will be present at the 2020 Annual Meeting. The representative will have an opportunity to make a statement if he or she desires to do so and to answer appropriate questions by shareholders.

Proposal 2—Ratification of the Appointment of Independent Auditor

        The Audit Committee has selected and appointed PwC as our Independent Auditor to audit our consolidated financial statements for the year ending December 31, 2020. Although ratification by shareholders is not required by law or by our Bylaws, the Audit Committee believes that submission of its selection to shareholders is a matter of good corporate governance. PwC has been the Company's auditor since 1997 and the Operating Partnership's auditor since 2013 and the Audit Committee considered the factors mentioned above in determining to reappoint PwC. Even if the appointment is ratified, the Audit Committee, in its discretion, may select a different Independent Auditor at any time if the Audit Committee believes that such a change would be in the best interests of the Company and its shareholders. If our shareholders do not ratify the appointment of PwC, the Audit Committee will take that fact into consideration, together with such other factors it deems relevant, in determining its next selection of Independent Auditor.

The Board recommends a vote "FOR" approval of the ratification of the appointment of PricewaterhouseCoopers LLP as our Independent Auditor for the current fiscal year.

Proposal 3—Advisory Vote to Approve Executive Compensation

        The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, or the Dodd-Frank Act, enables our shareholders to vote to approve, on an advisory basis, the compensation of our named executive officers as disclosed in this proxy statement in accordance with the SEC's rules. This is commonly known as, and is referred to herein as, a "say-on-pay" proposal or resolution.

        Our compensation programs are designed to clearly link annual and long-term financial results and shareholder return to executive rewards. The majority of each executive's total compensation is tied directly to goal achievement; this pay for performance approach ensures that the financial interests of our executives are aligned with those of our shareholders. Please refer to the section entitled "Compensation Discussion and Analysis" for additional details about our executive compensation programs, including information about the compensation of our named executive officers for 2019.

        The Compensation Committee annually reviews all elements of our compensation program for named executive officers to ensure its alignment with our philosophy and corporate governance approach, including its effectiveness in aligning the financial interests of our executives with those of our shareholders. Accordingly, pursuant to Section 14A(a)(1) of the Exchange Act, we are providing shareholders with the opportunity to approve the following advisory resolution:

        "RESOLVED, that the compensation paid to the Company's named executive officers, as disclosed in this proxy statement pursuant to Item 402 of Regulation S-K promulgated by the SEC, including the section entitled "Compensation Discussion and Analysis," compensation tables and narrative discussion, is hereby APPROVED."

The Board recommends a vote "FOR" the approval of this resolution.

        We are asking our shareholders to indicate their support for our named executive officers' compensation as described in this proxy statement. This say-on-pay proposal gives our shareholders the opportunity to express their views on our named executive officers' compensation. This vote is not limited to any specific item of compensation, but rather addresses the overall compensation of our named executive officers and our philosophy, policies and practices relating to their compensation as described in this proxy statement pursuant to Item 402 of Regulation S-K promulgated by the SEC.

Vote Required; Effect of Vote

        The affirmative vote of a majority of the votes cast on this proposal will be required for approval.

Table of Contents

        The say-on-pay resolution is advisory, and therefore will not have any binding legal effect on the Company or the Compensation Committee. However, the Compensation Committee does value the opinions of our shareholders and will take the results of the vote on this proposal into account in its future decisions regarding the compensation of our named executive officers.

Compensation Committee Interlocks and Insider Participation

        The Compensation Committee is comprised of the three independent Trustees listed below. The Committee members do not have any non-trivial professional, familial or financial relationship with the Chief Executive Officer, other executive officers or the Company, other than their relationships as Trustees.

Report of the Compensation Committee

        The Compensation Committee has reviewed the Compensation Discussion and Analysis and discussed it with management. Based on its review and discussions with management, the Committee recommended to our Board that the Compensation Discussion and Analysis be included in the Company's and the Operating Partnership's Annual Report on Form 10-K for 2019 and the Company's 2020 proxy statement. This report is provided by the following independent Trustees, who comprise the Committee.

Executive Summary

Our Business Model

        We own, manage, lease, develop and selectively acquire office and data center properties. The majority of our portfolio is in locations that support the United States Government and its contractors, most of whom are engaged in national security, defense and information technology ("IT") related activities servicing what we believe are growing, durable, priority missions (the "Defense/IT Locations"). We also own a portfolio of office properties located in select urban/urban-like submarkets in the Greater Washington, DC/Baltimore region with durable Class-A office fundamentals and characteristics (the "Regional Office Properties").

        Our strategy focuses on long-term value creation; we believe that we are positioned to continue to create value for our shareholders through low-risk accretive development.

2019 Business Highlights

        The Company had an outstanding year in 2019, meeting or exceeding our business objectives including operating leasing, government leasing, renewal leasing and retention rates, development leasing, capital recycling, year-end debt levels and development investment. Strong demand throughout our Defense/IT Locations translated into record leasing for new developments, strong vacancy leasing, and near-record leasing with the U.S. Government. Our 2019 accomplishments included the following:

•

achieved a total shareholder return ("TSR") of 30.8% during 2019;



•

same property cash NOI growth of 3.9% and funds from operations per share, as adjusted for comparability ("FFO per share"), of $2.03;



•

record total leasing of 4.9 million square feet and 2.2 million square feet of development leasing;



•

executed 586,000 square feet of development and vacancy leasing with the U.S. Government;



•

strong tenant retention of 77%, with core portfolio 93.1% occupied and 94.6% leased;



•

$357 million of equity proceeds raised to fund development investment; and



•

2.3 million square feet under development that were 79% leased.

2019 Compensation Highlights

        We design our compensation programs to link executive compensation to annual financial results and long-term TSR. We implement our pay-for-performance approach to ensure that the financial interests of our executives align closely with those of our shareholders by directly tying the majority of

26

Table of Contents

each executive's pay to the achievement of defined objectives. Highlights of our overall executive compensation program are outlined below:

•

Formulaic Annual Incentive Award ("AIA") Cash Bonuses with Pre-Determined Goals—100% of our CEO's AIA is formulaic and based on the achievement of pre-established corporate performance goals. Our COO and CFO individual objectives are only weighted at 25%, with the 75% remainder of their AIA calculated based on the achievement of our corporate goals. Our AIA program employs challenging hurdles aligned with our financial and operating success each year.



•

Long-Term Equity Incentive Plan ("LTIP") Awards Aligned with Our Shareholders—60% of our NEOs' equity compensation is granted in performance-based instruments that vest at the end of three-years, in amounts dependent upon the Company's TSR over that period relative to our peers in the SNL U.S. Office REIT Index. If our TSR during the measurement period is negative, we limit shares or units earned to target. The remaining 40% of our NEOs' equity award values are granted in time-based awards that vest ratably over a three-year period.



•

Pay-for-Performance Alignment—We maintain strong pay-for-performance alignment with approximately 64% of our CEO's 2019 compensation being variable, subject to the Company's performance under pre-defined formulas. The results of our formula-based incentive awards varied significantly in past years. This is consistent with our objective to provide executives with the opportunity to earn a higher relative level of total compensation when objectives are achieved and lower compensation when they are not.

        The tables below set forth the Company's CEO AIA payout and performance-based equity for the last five years:

Annual Shareholder Say-on-Pay Votes

        The Company provides its shareholders with the opportunity to cast an annual advisory vote on executive compensation (a "say-on-pay proposal"). At the Company's May 2019 annual meeting of shareholders, 98.6% of the shareholder say-on-pay proposal votes cast were in favor of the proposal. The Compensation Committee believes that this substantial approval was indicative of our shareholders' support of the Company's approach to executive compensation. The Committee will continue to consider shareholder feedback and the outcome of the Company's say-on-pay votes when making future NEO compensation decisions.

Compensation Objectives

        We tie the compensation of each executive to the Company's performance. We design compensation levels to be commensurate with those of executives performing similar responsibilities for an appropriate group of peer companies. Our executives' compensation relative to that of their counterparts in the peer group can vary based upon:

•

Skill + Experience:  The executive's skill and experience in the position, both overall and with the Company.



•

Performance:  The performance of the executive and the functions the executive oversees.



•

Internal Relativity:  The amount that we pay our other executives.



•

Market Competition:  The competition in the marketplace for the talents of the executive.

        We endeavor to provide our executives with the opportunity to earn a higher relative level of total compensation when warranted by superior results and performance. This approach allows us to attract, retain and motivate executives. Our incentive programs provide compensation in the form of both annual cash and multi-year equity awards to reward both short- and long-term performance. Each year, we review the allocation of total compensation between cash and equity awards in comparison to our peer group to assist in determining the compensation of our executives, in total and by component. The majority of our NEOs' compensation is performance-based, linked to a combination of annual and multi-year goals. Long-term equity awards represent the largest component of our NEOs' incentive compensation, as we describe in the section below entitled "LTIP."

Compensation Review Process

Role of the Compensation Committee of the Board

        The Board appoints the Compensation Committee, which acts on behalf of the Board. The Committee establishes and periodically reviews the Company's compensation philosophy and the adequacy of compensation plans and programs for executives. The section entitled "Our Board of Trustees" in this proxy statement describes other responsibilities of the Committee.

        Following recommendations by the Committee, the independent non-management members of the Board must approve NEO compensation decisions. The Board is responsible for oversight of the Committee's activities, except where the Committee has sole authority to act as required by an NYSE listing standard or applicable law or regulation. The Committee has complete and open access to management and any other resources of the Company required to assist it in carrying out its duties and responsibilities, including sole authority, in its discretion, to retain, set compensation for and terminate any consultants, legal counsel or other advisors.

Table of Contents

Use of Independent Consultants

        In determining executive compensation, the Compensation Committee makes use of analyses provided, at its request, by external consultants. From 2010 through mid-2019, the Committee utilized Pay Governance LLC ("Pay Governance") for these services. Pay Governance assisted the Compensation Committee in designing the 2019 compensation program. Beginning in mid-2019, following a search and selection process, the Committee changed to utilizing FTI Consulting ("FTI") to provide executive compensation consulting services. The Committee reviewed the independence of both Pay Governance's and FTI's advisory roles relative to the six consultant independence factors adopted by the SEC to guide listed companies in determining the independence of their compensation consultants, legal counsel and other advisors. Following its review, the Committee concluded that Pay Governance and FTI have no conflicts of interest and provide the Committee with objective and independent executive compensation advisory services. Pay Governance and FTI provided data relevant to reviewing executive compensation, discussions of compensation practices and observations to the Committee regarding compensation programs and pay levels. Neither Pay Governance nor FTI performed any work for the Company at the direction of management during 2019. As appropriate, the Committee meets with its independent consultant in executive session without management present.

Role of Management

        The CEO meets with the Compensation Committee to review our compensation philosophy, present analyses based on the Committee's requests and discuss the compensation recommendations the Committee makes to the Board. The CEO presents management's perspective on business objectives, discusses the effect of business results on compensation recommendations, reviews executive compensation data and discusses the other NEOs' performance.

        Our Director of Human Resources, who reports directly to our CEO, also takes direction from, and provides suggestions to, the Committee, oversees the formulation of compensation plans incorporating the recommendations of the Committee, and assists the Chairman of the Compensation Committee in preparing agendas for the meetings.

        Our CEO and Director of Human Resources attend Compensation Committee meetings, but do not attend portions of Board and Compensation Committee meetings intended to be held without members of management present, including those relating to the CEO's compensation.

Compensation Comparisons

        To meet our objectives of attracting and retaining superior talent, we annually review pay practices of our peers. We do not base our NEO pay levels solely on their relationship to those of our peers. We use market data to help confirm that our pay practices are appropriate. We review our peer group annually, seeking to include companies that are similar in size and business structure to us. Within this peer group, we then focus on executives with responsibilities like those of our executives. In order to provide data for this analysis, the independent consultant obtains an understanding of the goals, objectives and responsibilities of each executive position based on reviews of job descriptions and discussions with management and the Committee.

        During 2019, the Compensation Committee worked with FTI to review the composition of the peer group to account for changes in both our business and the businesses of the companies in the peer group. We evaluated companies for inclusion based upon business focus, product mix, market

30

Table of Contents

capitalization, total enterprise value, geographic location and overall balance and composition of the group. Following this analysis, we revised the peer group to:

•

remove three comparator companies: Franklin Street Properties, Office Properties Income Trust (formerly Government Properties Income Trust) and PS Business Parks, due to the lack of meaningful compensation data provided by those companies;



•

remove TIER REIT due to its merger with Cousins Properties Incorporated; and



•

add four companies: American Assets Trust Inc., Easterly Government Properties Inc., JBG Smith Properties and STAG Industrial, Inc. These companies have significant office or industrial holdings, location within our geographic area and/or implied equity market capitalization and total enterprise value within our parameters.

The updated peer group of 14 includes a combination of publicly traded office, industrial and diversified REITs, with a heavier weighting on office companies. The companies included in the 2019 peer group were:

        For purposes of reviewing NEO total compensation relative to competitive practices, the independent consultant provided peer group compensation data to the Compensation Committee. The Compensation Committee compared our NEO base salaries, AIAs, LTIP awards and total compensation to information for comparable positions in each of the peer group companies. The independent consultant provided detailed information at the 25th, 50th and 75th percentiles and the average in order to assist the Committee in understanding how the Company's executive compensation compared to that of its peers.

        Consistent with our practice in prior years, the independent consultant also conducted a comprehensive pay for performance assessment of the Company's executive compensation program and the linkage between organizational performance and the value of the compensation delivered to the executives.

Base Salary

        Base salary is the fixed element of pay intended to attract and retain executives. We determine our NEOs' base salaries with consideration of their scope of responsibilities, individual skills and experience. They are eligible for periodic increases in their base salary as a result of individual performance. The Committee also considers peer group data, relativity between the NEOs and budget considerations.

        Annual base salary actions in 2019 are shown below. These changes are reflective of each NEO's strong individual objective achievement where applicable, creation of significant opportunity for the

Company's business development, overachievement of the Company's 2018 performance scorecard and each NEO's position relative to peer base salaries:

        Effective January 1, 2019, the Board increased Mr. Budorick's base salary by $53,967, or 8.4%, in recognition of his performance as CEO and to move Mr. Budorick's base salary towards the median of the competitive range, reflective of his tenure and contributions. The Board determined that the base salaries for 2019 shown above for Mr. Adkins and Mr. Mifsud appropriately reflect their level of responsibility in the Company based on a comparison to market data and to their peers.

AIAs

        We used a scorecard approach to drive the achievement of strategic business objectives, measure Company performance, and determine the executives' AIAs. This approach rewards our executives for the achievement of strategic objectives, thereby creating long-term value for our shareholders. We established performance goals in each of these areas in the first quarter of 2019.

        There are four established achievement levels for each objective within the scorecard:

•

Threshold [50% of Target Payout]:  If the Company does not achieve threshold level performance of the weighted average of the scorecard objectives, then we will not pay AIAs.



•

Target [100% of Target Payout]:  Approximates management's estimate of the related objective as set forth in the annual budget approved by the Board; this level of performance is intended to be challenging, yet attainable.



•

High [150% of Target Payout]:  Intended to be attainable with superior performance.



•

Maximum [200% of Target Payout]:  Only available as a score for each specific objective and included in the weighted average result. This level is intended to capture outstanding performance that is difficult to attain.

The aggregate scorecard outcome is limited to the high achievement level of 150%. Actual awards are determined once the Company finalizes actual results and performance with respect to these objectives and interpolates between performance levels as appropriate. The Committee retains the authority to recommend increases or decreases to AIAs at its discretion.

2019 AIA Performance Objectives

        The Committee, with the assistance of management, developed the 2019 corporate scorecard using the Company's Board-approved annual budget and information regarding other related business and operations initiatives, including guidance provided to the investment community, and in light of the market environment for our business. The scorecard consists of three categories of corporate objectives, weighted as follows:

1.

Financial Measures—60%


The Company's target financial measures for 2019 were the following:

o

FFO per share of $2.04 (35%);



o

same property cash NOI growth of 2.25% (15%); and

32

Table of Contents

o

net debt plus preferred equity to in-place adjusted EBITDA ratio at year end ("debt plus preferred equity ratio") of 6.00x (10%).

FFO per share and cash NOI are measures frequently used by equity REITs to evaluate performance. FFO per share measures management's effectiveness in executing the business plan. Same property cash NOI growth measures the strength of our investment strategy. We use these measures because we believe they are useful metrics in evaluating the effectiveness of our operations and are core objectives in our annual budget. Further, we believe that growth in the two operating measures in the long-term contributes to an increase in shareholder value and, as a result, that linking compensation to these measures helps to align the interests of our NEOs with those of our shareholders. We use the debt plus preferred equity ratio to evaluate borrowing levels relative to our operating performance.

2.

Development Leasing Volume—30%


This objective focused our efforts on leasing 900,000 square feet in development properties. Our primary business strategy focus is growth through low-risk, new property development to increase the Company's overall value. This objective incentivized our executives to maximize the value of our development pipeline, thereby increasing the Company's value.

3.

Core Portfolio Year End Occupancy—10%


This objective related to achievement of target year-end occupancy of 92.0% in what we have identified as our core portfolio, which is subject to adjustment each year based upon changes in our portfolio. We believe that this objective incentivized efforts toward leasing of vacant space and renewals, which further supports future cash flow and net asset value growth.

        The Committee approved our COO and CFO individual objectives, which are tailored to the operations of the business unit for which they were each responsible and include the management of the mitigation of risks identified by the Company's ERM assessment. As appropriate, individual objectives were either quantitative or qualitative in nature. The Committee evaluated the achievement of our 2019 Corporate Objectives to assess the CEO's performance, and the CEO recommended his assessment of the other executives' achievement for approval by the Committee. The level of objective achievement resulted in the executives' calculated AIAs.

2019 AIA Targets

        The Committee sets target payouts in consideration of peer levels and differentiation between the NEOs. This is the level paid when the Company achieves target performance. The expectation is that actual payouts will compare more favorably to peer levels when performance is exceptional. The table below sets forth the 2019 potential award payouts as a percentage of the executive's base salary:

        Final award levels are determined based on a review of the Corporate Objectives and each executive's achievement of their individual objectives. While our CEO's AIA is based 100% on achievement of the Corporate Objectives, the actual award payout can be influenced by other factors identified at the Committee's discretion. Mr. Adkins' and Mr. Mifsud's AIAs are based 75% on achievement of the Corporate Objectives and 25% on achievement of their individual performance

objectives, also subject to the Committee's discretion. COO and CFO individual objective achievements are scored between 0% and 150%. The following is a summary of individual performance objectives for our COO and CFO, all equally weighted:

•

2019 AIA Results

        Following is the scorecard reflecting final 2019 results:

        The actual Financial metric of the Corporate Objectives, as reflected above, included adjustments by the Committee to exclude the effect of the deferral of a planned capital event and higher than expected property dispositions. The Committee deemed these adjustments, which reduced the final score, necessary to reflect the operating performance for the year, which reduced the final score. These weighted objective outcomes resulted in achievement at 138.9% of target for our Corporate Objectives, reduced from an unadjusted score of 140.9% of target. The Committee elected to pay the NEO cash incentives at the 138.9% level without implementing any other discretionary adjustments.

        The table below shows the actual AIAs for 2019, reflective of calculated achievement of our annual scorecard goals, which were designed to focus our NEOs on our primary short-term business objectives:

LTIP

        We design our LTIP awards to align the interests of the executives with those of our shareholders by rewarding them for sustained performance. Since these awards vest over time, we believe they also encourage the executives to remain with the Company.

        The Board awarded the NEOs' 2019 LTIP awards in the following proportions, consistent with those of prior years:

•

Performance-Based—The Board awarded 60% of our NEOs' LTIP awards in the form of performance-based equity which aligns their interests with those of our shareholders. The number of awards earned at the end of the program's three-year performance period depends entirely on TSR relative to our peer group. If the Company's results are in the bottom quartile, the NEOs will not earn any equity. If the Company's results are in the top quartile, NEOs earn the 200% maximum. If the Company's TSR during the measurement period is negative, the maximum number of shares or units that may be earned is limited to 100% of the target level. We believe that the performance-based plan further motivates our executives to achieve strong returns over an extended period.

35

Table of Contents

•

Time-Based—The Board awarded the remaining 40% of the NEOs' LTIP awards in the form of time-based equity, with a three-year ratable vesting period. We believe this portion of their award reinforces our goal of retention, in addition to incenting our executives to increase shareholder value over an extended timeframe.

        The Committee believes that awarding a majority of the executive LTIP awards using performance-based grants provides for the following:

•

Alignment of Executives with Shareholders:  Executive and shareholder risks and rewards are more closely aligned by a long-term, forward-looking plan focused on relative TSR;



•

Retention:  Retention of key executives is enhanced due to the payout opportunities available in the event of superior relative performance;



•

Pre-Determined Levels:  Grants and potential awards under the plan are clearly determined and communicated to the NEOs at the beginning of the performance period; and



•

Dividend or Distribution Timing:  Dividends are accrued but not paid out on the equity awards until, and to the extent, they are earned at the end of the defined performance period, thus putting additional compensation at risk based on performance, notwithstanding nominal distributions for PB-PIUs made for tax qualification purposes.

Profit Interest Unit Compensation

        In 2019, the Compensation Committee granted our NEOs the option to select equity compensation in the form of Profit Interest Units ("PIUs"). PIUs are long-term incentive units in our Operating Partnership as set forth under our 2017 Omnibus Equity Incentive Plan. The Compensation Committee believes that providing long-term incentive compensation in the form of PIUs aligns our NEO interests with those of shareholders. Award value levels for each NEO are approved by the Board, which do not change as a product of an NEO's selection of PIUs. PIUs may be subject to vesting requirements, as determined prior to grant.

        The partnership will maintain at all times a one-to-one correspondence at all times between PIUs and common units in our operating partnership ("common units") for conversion, distribution and other purposes, except as provided in the partnership agreement, and will make corresponding adjustments to the PIUs to maintain such correspondence upon the occurrence of specified adjustment events. A PIU will automatically convert to a Common Unit once vested. Once converted, the holder of the Common Unit will have all rights set forth in the partnership agreement.

        The Compensation Committee granted two types of PIUs in 2019. Time-based profit interest units ("TB-PIUs") and performance-based profit interest units ("PB-PIUs"), which are substantially similar to time-based RSs and performance-based performance share units ("PSUs"), respectively. Holders of TB-PIUs will receive the same quarterly per-unit distributions as common units in our Operating Partnership, which equal the per-share dividends on our common shares. Holders of PB-PIUs receive quarterly per-unit distributions equal to ten percent of the distributions made with respect to the equivalent number of common units in our Operating Partnership. This form of equity compensation and the distributions made during the unvested period is typical for REITs.

Performance-Based Equity Awards Made in 2019

        On January 1, 2019, the Board granted performance-based equity to the NEOs valued at 60% of their 2019 LTIP awards. All three NEOs elected to receive the entirety of their performance-based awards in PB-PIUs as set forth below:

        The Board seeks to provide compensation opportunities that will attract, retain and motivate superior executive personnel. During our annual review of peer compensation data related to LTIP awards, we developed these target award percentages using a broad perspective and multiple data points, including peer long-term equity award data, the Company's desire to differentiate between NEOs and the total target compensation to be delivered to NEOs.

        These grants have a performance period that began on January 1, 2019 and will conclude on the earlier of (1) December 31, 2021, (2) the date of a change in control or (3) the date of a qualified termination.

        The actual number of common units that the Company will distribute at the end of the performance period ("earned PB-PIUs") will be determined based on the percentile rank of the Company's TSR relative to those of the component companies in the SNL U.S. Office REIT Index, as set forth in the following schedule. The Company implemented an index-only relative TSR ("rTSR") comparison for the January 1, 2019 NEO performance-based equity grants. In previous years, the Company used the same peer group for compensation benchmarking and rTSR comparison. This delineation aligns our practices with that of the majority of our peer group, stabilizes the size of the rTSR comparison group and maintains the peer group's integrity for a pure compensation comparison.

        We use interpolation between points, with the exception that if the Company's TSR during the measurement period is negative, the maximum number of PB-PIUs that may be earned notwithstanding

37

Table of Contents

relative TSR achievement above the target level is limited to 50% of the PB-PIUs granted (target level):

        At the end of the performance period, the Company, in settlement of the award, will issue a number of vested PIUs equal to the number of earned awards in settlement of the award plan, and pay cash equal to the excess, if any, of: the aggregate distributions that would have been paid with respect to the vested PIUs issued in settlement of the earned awards through the date of settlement had such vested PIUs been issued on the grant date over the aggregate distributions made on the PB-PIUs over the performance period. PIUs do not carry voting rights.

        The performance period for the March 2017 PSU grant ended on December 31, 2019. The Company's TSR over the three-year performance period ranked at the 27^th percentile relative to our peers' TSR, resulting in a payout of 53% of the target award to Mr. Budorick, Mr. Adkins and Mr. Mifsud in 2020.

        If a performance period ends due to a change in control or qualified termination, the performance-based program terminates and any payout to the executives is prorated based on the portion of the three-year performance period that has elapsed. We believe that this feature of the program is appropriate, as it would only compensate our executives for the time worked and the results achieved to-date. If the employee terminates their employment, or the Company terminates employment for cause, the NEO forfeits all PB-PIUs.

Time-Based Equity Awards Made in 2019

        In November 2018, the Board approved grants awarded March 1, 2019 of time-based equity to the NEOs as set forth below, valued at 40% of their LTIP awards. All three NEOs elected to receive the entirety of their 2019 time-based awards in TB-PIUs as set forth below:

        Prior to vesting, TB-PIUs carry substantially the same rights to distributions as non-PIU common units. Time-based equity awards vest in equal one-third increments annually over a three-year period if the NEO remains employed by the Company. The value of time-based equity awarded was determined using the closing price on the NYSE of the Company's common shares on the grant date.

        The Company has not issued stock options since 2009. There are no stock options outstanding and none of our current NEOs were ever issued stock options. The Company has never issued stock appreciation rights.

2020 Compensation Program Updates

        Based on the Company's commitment to align pay and performance, the following actions will occur, or have already occurred, for 2020:

•

AIAs:  The 2020 AIA plan will use the Company performance scorecard measurement process with emphasis on key business growth drivers and a continued focus on the achievement of financial and operational goals.



•

LTIP Awards:  The Company will continue to provide the majority of our NEOs' LTIP awards in the form of performance-based equity and the balance will be in the form of time-based equity awards. The Company granted Mr. Budorick, Mr. Adkins and Mr. Mifsud LTIP awards in the form of 60% PB-PIUs awarded on January 1, 2020 and 40% TB-PIUs awarded on March 1, 2020. This form of compensation aligns with industry practice and strengthens the retention aspect of our program while continuing to deliver the majority of annual LTIP awards in the form of performance-based equity. The awards to Mr. Adkins were forfeited as of March 16, 2020 in connection with his resignation.



•

Compensation Benchmarking Peer Group:  At the conclusion of the re-evaluation of our peer group for 2019, the Compensation Committee approved the use of the same peer group for 2020 executive compensation benchmarking efforts. Management and the Committee believe that this peer group reflects our office, diversified and specialty REIT emphasis and provides comparability to companies with which we compete for talent, capital and market share.

Retirement Benefits

        We design our retirement benefits to assist our executives in accumulating sufficient wealth to provide income during their retirement years. We intend the retirement benefits to attract and retain executives and to encourage such executives to save money for their retirement, while allowing us to maintain a competitive cost structure. Information pertaining to our retirement benefits is set forth below.

401(k) Plan

        Our executives participate in a 401(k) defined contribution plan covering substantially all of our employees. The plan provides for Company matching contributions in an amount equal to an aggregate of 4% on the first 6% of participant pre-tax and/or after-tax contributions to the plan.

Nonqualified Deferred Compensation Plan

        We offered our senior management team, including director level and above, as well as our Trustees the ability to participate in a nonqualified deferred compensation plan. None of our current NEOs chose to participate in this plan, and the Company froze additional entry into the plan effective December 31, 2019. Until December 31, 2019, this plan allowed for the deferral of up to 100% of a participant's cash compensation on a pre-tax basis and enabled such participants to receive a tax-deferred return on such deferrals. Both senior management and Trustees were given the choice to defer their salary/board fees during a December enrollment period for the following year's salary or board fees. Participants may diversify their investments among the plan's selected investment alternatives. The plan does not guarantee a return or provide for above-market preferential earnings. The plan is not qualified under the Employee Retirement and Income Security Act of 1974. The deferral account balances increase or decrease in value based on the performance of the investments selected by the participants. Participants in this plan deferred their payments for at least three years from the beginning of the calendar year following the year in which (s)he elects the deferral. Participants chose to receive account balances in a lump sum or annual installments either upon

separation or at a specified future date. For participants who separate from service, payments according to their election(s) will commence within 60 days of separation unless the participant is a "specified employee," as defined in the plan, in which case any distribution shall not be made for six months from termination. For participants who elected specified future payment dates, those payments will commence on the chosen dates. Payments are due to parties designated by the participant in lump sum upon the death of a participant. Participant account balances are fully vested at all times and participation in the deferred compensation plan was voluntary.

Severance and Change in Control Benefits

        The Company does not enter into executive employment agreements with our NEOs. Consistent with best practice, the Company utilizes a Change in Control ("CIC") Plan. The CIC Plan provides for a severance package in the event of the termination of the executive's employment (1) within 12 months of a change in control of the Company, as defined in the CIC Plan, or (2) by us without cause or by the employee based upon constructive discharge. The CIC Plan participants must agree to certain non-competition, non-solicitation and confidentiality covenants, and must deliver a release of claims in order to receive payments and benefits under the CIC Plan. We believe that the CIC Plan affords our executives with financial security in the event of a change in control, while ensuring that the Company is able to retain the appropriate knowledge and expertise needed during a CIC. We also believe that having the CIC Plan encourages the continued dedication of the executives evaluating potential transactions involving the Company that might result in a change in control.

        Due to the authority vested with the executives and the knowledge of Company proprietary information held by such individuals, the Company must protect its real estate interests in each of its major markets. For this reason, the CIC Plan includes a non-compete provision for a 12-month period following termination of employment. The CIC Plan also requires delivery of a release of claims against the Company and related parties in order to be eligible to receive severance payments under such agreement.

Other Benefits and Perquisites

        As employees, our executives are eligible to participate in employee benefit programs available to our other employees, including medical, dental, life and disability insurance, as well as participation in an Executive Wellness Program. As with all other employees of the Company, our executives also receive a monetary award for achieving service anniversary milestones. The value of these benefits that executives may receive is essentially equivalent to that offered to the broader management and/or employee group and is included in the tables entitled "Summary Compensation Table" and "All Other Compensation." As demonstrated by the provisions of our CIC Plan, we do not enter into agreements that contain perquisites that may be considered poor pay practices.

Tax Compliance Policy

        Generally, for federal income taxes, compensation expense for almost all U.S. employers is fully tax-deductible. The Tax Cuts and Jobs Act, passed in 2017, eliminated a previous exemption under Section 162(m) of the Internal Revenue Code for performance-based compensation for tax years beginning after 2017, so that annual compensation in excess of $1 million paid to our NEOs who are covered employees under Section 162(m) will generally not be tax deductible, even if such compensation is performance-based or paid following termination of employment.

        We qualify as a REIT under the Code and, as a result, generally are not subject to federal income taxes. As a result, the Tax Cuts and Jobs Act or the payment of compensation which is not deductible due to Section 162(m) of the Code did not have a material adverse federal income tax consequence to us.

        Section 409A of the Code provides that amounts deferred under nonqualified deferred compensation plans are includable in an employee's income when no longer subject to a substantial risk of forfeiture unless certain requirements are met. If the requirements under Section 409A of the Code are not met, an employee could be subject to additional taxes, interest and penalties. The Company, with the assistance of external counsel, continuously reviews all of its various executive compensation and benefits plans and arrangements to ensure compliance with Section 409A of the Code.

        Under Sections 280G of the Code, a corporation will be denied an income tax deduction on any "excess parachute payments" made to certain executives in connection with a change in control, and the executives receiving such excess parachute payments will be subject to a non-deductible 20% excise tax, in addition to regular federal and state income tax. The Compensation Committee considers the impact of Section 280G of the Code on our compensation plans and arrangements with our NEOs and none of these plans provide for an excise tax gross-up pursuant to Section 280G of the Code.

Executive Ownership and Capital Accumulation

        We believe that the ownership of shares in the Company by NEOs assists in aligning their interests with those of our shareholders. Therefore, we have the following share ownership guidelines for our Trustees and NEOs:

        The ownership guidelines generally include common shares beneficially owned by the respective individuals, including unvested RSs and TB-PIUs, certain share equivalents under Company sponsored plans and units in the Company's Operating Partnership owned by such individuals, although the guidelines exclude outstanding stock options, PSUs and PB-PIUs, and any shares or securities pledged as collateral for a loan. Newly appointed independent Trustees and covered NEOs have five years to comply with these guidelines from their date of appointment or promotion.

Trading Controls

        We require our executives and Trustees to receive the permission of our General Counsel and Secretary prior to entering into transactions in Company shares or share equivalents. Executives and Trustees are subject to blackout periods on the trading of Company shares for a period of time beginning at each quarter-end and a period following the release of earnings for each quarter-end.

        Executives and Trustees bear full responsibility if they violate the Company Policy Statement on Securities Trading by permitting shares to be bought or sold without pre-approval by our General Counsel or when trading is restricted. The Policy Statement on Securities Trading also specifically prohibits NEOs and Trustees from participating in any hedging activities in Company shares. The Company also has an anti-pledging policy. Subject to the terms of the policy, executives may not (1) hold securities of the Company in a margin account or pledge securities of the Company as collateral for a loan, or (2) enter into hedging or monetization transactions or similar arrangements with respect to securities of the Company.

Compensation and Risk

        We reviewed the elements of executive compensation to determine whether they encourage excessive or unintended risk-taking and concluded that:

•

significant weighting toward long-term equity compensation discourages short-term risk taking;



•

vesting schedules for time and performance-based equity cause management to have a significant amount of unvested awards at any given time, which creates longer term perspectives and focus;



•

performance goals are set based on a business plan approved by the Board, and their achievement does not automatically entitle management to AIAs or LTIP awards, which are at the discretion of the Board;



•

the Board exercises approval rights over significant investment decisions that could expose the Company to long-term risks;



•

share ownership guidelines require management to hold a certain amount of our stock such that the NEOs' interests are aligned with shareholders; and



•

our clawback policy allows the Company to recoup incentive awards paid to executives and certain other key employees in the event such recoupment is warranted.

Accordingly, our executives and Board concluded that risks arising from our policies and practices for compensating employees are not reasonably likely to have a material adverse effect on the Company.
