The Board of Trustees of the Trust has fixed the close of business on February 24, 2017 as the record date for the meeting. Only shareholders of record at the close of business on that date are entitled to notice of and to vote at the meeting and any adjournment or postponement thereof.

Proxies are being solicited by the Board of Trustees of the Trust. Reference is made to the Proxy Statement included in our proxy materials for further information with respect to the business to be transacted at the meeting.

LIBERTY PROPERTY TRUST
PROXY STATEMENT
ANNUAL MEETING OF SHAREHOLDERS
To Be Held May 18, 2017

This proxy statement is being furnished in connection with the solicitation of proxies by the Board of Trustees (the "Board of Trustees" or the "Board") of Liberty Property Trust, a Maryland real estate investment trust (the "Trust" or the "Company"), for use at the Trust's 2017 Annual Meeting of Shareholders (the "Meeting") to be held at The Logan Hotel, One Logan Square, Philadelphia, PA 19103 on May 18, 2017 at 11:00 a.m., local time, and any adjournment or postponement thereof, for the purposes set forth in the foregoing notice and more fully discussed herein. Only shareholders of record at the close of business on February 24, 2017 (the "Record Date") shall be entitled to notice of and to vote at the Meeting. We are distributing to our shareholders a Notice of Internet Availability of Proxy Materials (the "Notice of Internet Availability") on or about April 5, 2017.

If the enclosed proxy is properly executed and received by the Trust prior to voting at the Meeting, the common shares of beneficial interest, $0.001 par value per share, of the Trust (the "common shares") represented thereby will be voted in accordance with the instructions marked thereon. In the absence of instructions, the common shares represented by the enclosed proxy will be voted FOR the nominees of the Board of Trustees in the election of trustees, FOR approval of the advisory vote to approve the compensation of the Trust's named executive officers, FOR the "1 Year" frequency of voting on the compensation of the Trust's named executive officers and FOR ratification of the selection of Ernst & Young LLP as the Trust's independent registered public accounting firm for 2017. Management does not intend to bring any matter before the Meeting other than as indicated in the notice and does not know of anyone else who intends to do so. If any other matters properly come before the Meeting, however, the persons named in the enclosed proxy, or their duly constituted substitutes acting at the Meeting, will be authorized to vote or otherwise act thereon in accordance with their judgment on such matters.

Any proxy may be revoked at any time prior to its exercise by notifying the Secretary of the Trust in writing prior to the time of the Meeting, by delivering a duly executed proxy bearing a later date or by attending the Meeting and voting in person.

On the Record Date, the Trust had 146,992,276 common shares outstanding and entitled to vote at the Meeting. Each holder of common shares is entitled to one vote per share held of record by such holder on the Record Date. There must be present at the Meeting in person or by proxy shareholders entitled to cast a majority of all the votes entitled to be cast to constitute a quorum for the Meeting. Common shares represented at the Meeting in person or by proxy but not voted on one or more proposals will be included in determining the presence of a quorum, but will not be considered cast on any proposal on which they were not voted. Thus, abstentions and broker "non-votes" are deemed to be present at the Meeting for the purpose of determining whether a quorum is constituted, but are not deemed to be votes cast at the Meeting. A broker "non-vote" occurs when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power on that item and has not received instructions from the beneficial owner.

Abstentions and broker "non-votes" will affect each of the proposals described in this proxy as follows:

A majority of all votes cast in an election for trustees means that the number of shares voted "for" a nominee for trustee must exceed the number of votes cast as "withheld" from that nominee. In addition, the Trust's corporate governance guidelines provide that if a nominee for trustee who already serves as a trustee is not elected by a majority of the votes cast, the trustee will offer to tender his or her resignation to the Board of Trustees. The Corporate Governance and Nominating Committee of the Board of Trustees will then make a recommendation to the Board of Trustees on whether to accept or reject such resignation, or whether other action should be taken. The Board of Trustees will act on the Corporate Governance and Nominating Committee's recommendation and publicly disclose its decision and the rationale behind it within 90 days from the date of the certification of the election results. Any such trustee who tenders his or her resignation will not participate in the Board of Trustee's decision. There is no cumulative voting in the election of trustees.

A majority of the votes cast at the Meeting shall be sufficient to approve any other matter that may properly come before the Meeting, unless more than a majority of the votes cast is required by the Declaration of Trust or applicable law.

In accordance with the rules of the Securities and Exchange Commission, instead of mailing a printed copy of our proxy materials to each shareholder of record or beneficial owner, we are furnishing our proxy materials (this proxy statement, the proxy card and the 2016 annual report) by providing access to these materials on the internet. 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 Internet Availability of Proxy Materials will be mailed to shareholders on or about April 5, 2017. We are providing the Notice of Internet Availability in lieu of mailing the printed proxy materials and instructing stockholders as to how they may: (1) access and review the 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. A request to receive proxy materials in printed form by mail or by e-mail will remain in effect until such time as the submitting shareholder elects to terminate it.

This proxy statement and our 2016 annual report to shareholders are available at www.libertyproperty.com in the "Investors" section.

There are currently nine members of the Board of Trustees. All nine trustees are being proposed for election at the Meeting to serve until the Annual Meeting of Shareholders to be held in 2018 and until their successors are duly elected and qualified. Each of the nominees for election as trustee currently serves as a trustee of the Trust.

A proxy signed in the enclosed form will be voted FOR the election of the nominees named below, unless a contrary instruction is given.

Management believes that each of its nominees is willing and able to serve the Trust as trustee. If any nominee at the time of election is unable or unwilling to serve or is otherwise unavailable for election, and as a consequence thereof other nominees are designated, the persons named in the proxy or their substitutes will have the discretion and authority to vote or to refrain from voting for other nominees in accordance with their judgment.

The following is a brief description of the nominees for election as trustee of the Trust. The descriptions for the trustees set forth the experience, qualifications, attributes and skills that have led the Board to conclude that these nominees should serve as trustees of the Trust.

The Board of Trustees recommends a vote FOR the election of each nominee. Assuming a quorum is present at the Meeting, a majority of all the votes cast at the Meeting shall be sufficient to elect a trustee.

His leadership role in both the not-for-profit world and the public company arena has provided him with valuable opportunities to interact with government and business leaders in market segments of importance to the Trust.

Ms. Lachman's extensive experience as a specialist in real estate investment management and her ongoing advisory work enable Ms. Lachman to make valuable contributions to the Board, particularly in the area of strategic real estate investment analysis. Additionally, her experience as a director of another public company gives her insight into governance and related best practices, which enable her to make significant contributions as a Board member.

In 2015 Ms. Lachman reached the age of 72 and, in accordance with the Trust's corporate governance guidelines, offered each year beginning in 2014, not to stand for reelection as a Trustee at the Annual Meetings of Shareholders of the Company. The Board of Trustees evaluated Ms. Lachman's offers and in each case made a determination not to accept the offer, noting that Ms. Lachman continues to make significant contributions to the Board and that her industry awareness

and depth of real estate experience are critical to the Board. Accordingly, the Board is recommending Ms. Lachman as a trustee nominee for re-election.

Corporate Governance and Nominating Committee. The Board's Corporate Governance and Nominating Committee meets to address matters regarding corporate governance and makes recommendations to the Board regarding nominees for positions on the Board. In making such recommendations, the Corporate Governance and Nominating Committee seeks nominees who have the highest personal and professional character and integrity, who possess appropriate characteristics, skills, experience and time to make a significant contribution to the Board of Trustees, the Trust and its shareholders, who have demonstrated exceptional ability and judgment, and who will be most effective, in the context of the whole Board of Trustees and other nominees to the Board, in perpetuating the success of the Trust and in representing the interests of its shareholders. In accordance with its charter, the Corporate Governance and Nominating Committee considers diversity of race, gender and national origin as one of a number of attributes it looks for in a candidate for the Board of Trustees. It is a goal of the Board to achieve greater diversity. The Corporate Governance and Nominating Committee has employed and may continue to employ professional search firms (for which it pays a fee) to assist it in identifying potential members of the Board of Trustees with the desired skills and disciplines. The Corporate Governance and Nominating Committee will consider nominees for trustee proposed by shareholders in accordance with the procedures set forth in this proxy statement under "Corporate Governance—Shareholder Nominations for Trustees." Nominees proposed by shareholders will be considered using the same criteria and in the same manner as all other nominees are considered.

The members of the Corporate Governance and Nominating Committee are Mss. Dietze (Chair) and Lachman, and Messrs. DeLoach and Fernandez, all of whom are independent, as independence is defined by the applicable listing standards of the New York Stock Exchange. Mr. Garton, in his role as

Lead Independent Trustee, also participates in the meetings of the Corporate Governance and Nominating Committee. The Corporate Governance and Nominating Committee met five times during the last fiscal year. See "Report of the Corporate Governance and Nominating Committee."

Copies of the written charters of the Audit, Compensation and Corporate Governance and Nominating Committees are posted under the "Investors" section of the Trust's web site at www.libertyproperty.com, and are also available without charge at the written request of any shareholder of the Trust. Such requests should be directed to the Vice President of Investor Relations at the address of the Trust appearing on the Notice of Annual Meeting that accompanies this proxy statement.

The Board of Trustees held nine meetings last year, including four by teleconference. Additionally, the Board conducted four informational calls. Each trustee of the Trust attended at least 75% of the meetings of the Board of Trustees and meetings held by all committees on which such trustee served.

In 2016, trustees who were not also officers and full-time employees of the Trust were compensated in accordance with the following policy. These trustees received an annual trustee retainer in the amount of $40,000 in cash and a grant of unrestricted common shares with a total grant date fair value of $87,500. The Lead Independent Trustee received an additional annual retainer of $30,000 for performing the duties and responsibilities of that position. Additionally, trustees received a fee of $1,500 for each Board meeting that such trustee attended in person or telephonically; however, this fee was only $500 for teleconference Board meetings if such meetings addressed only routine matters and for participation in any informational call held to supplement the regularly scheduled Board meetings. Trustees also received a fee of $5,000 for each committee on which they served, a fee of $1,000 for each committee meeting they attended in person and a fee of $500 for each committee meeting attended by teleconference. The Chair of the Audit Committee received an additional annual fee of $15,000, and the Chairs of the Corporate Governance and Nominating Committee and the Compensation Committee each received an additional annual fee of $9,000.

For 2017, the Corporate Governance and Nominating Committee revised the compensation package for the trustees, with the guidance of an independent compensation consultant and based on best practices and market conditions among the Company's peers. All per-meeting and per-call fees have been eliminated. The annual retainer has been changed to $72,000, with an additional retainer in the amount of $25,000 for the Lead Independent Trustee. The committee chair retainer for the Audit Committee Chair will be $20,000, and the committee chair retainer for the chairs of the other two standing committees will be $15,000. The committee member retainer for non-chair members of the Audit Committee (including the Lead Independent Trustee as ex officio member) will be $8,500, and the committee member retainer for non-chair members of the other committees (including the Lead Independent Trustee as ex officio member) will be $5,000. All retainers are payable in cash. The stock-based compensation to the Trustees will be in the form of a grant of unrestricted common shares of the Company with value of $91,500, based on the average closing share price of the Company's shares during the 30-calendar-day period up to and including the grant date.

Additionally, all trustees are entitled to be reimbursed for travel and lodging expenses associated with attending Board and committee meetings. Trustees who are officers and full-time employees of the Trust are not entitled to receive any separate compensation for service as a trustee.

PROPOSAL 2—ADVISORY VOTE TO APPROVE
THE COMPENSATION OF THE TRUST'S NAMED EXECUTIVE OFFICERS

SEC rules require us to hold, at least once every three years, an advisory vote to approve the compensation of our named executive officers as described in the proxy statement (commonly referred to as "Say-on-Pay"). We have committed to including a Say-on-Pay vote on an annual basis, at least until such time, if any, as our shareholders express a preference for a less frequent basis. Thus, we have included the following Say-on-Pay vote, pursuant to which our shareholders are being asked to vote on the following resolution:

The compensation of our named executive officers is disclosed in the Compensation Discussion and Analysis, the compensation tables, and the related disclosures contained on pages 14 to 40 of this proxy statement. As is discussed below in those disclosures with respect to certain modifications to our compensation structure implemented in 2016, we regularly monitor our compensation policies and decisions to ensure that they are focused on pay-for-performance principles and are strongly aligned with the long-term interests of our shareholders. Compensation of our named executive officers is designed to enable us to attract and retain talented and experienced senior executives to lead the Company successfully in a competitive environment.

Your vote on this Proposal 2 is advisory, and therefore not binding on the Trust, the Compensation Committee, or the Board. The vote will not be construed to create or imply any change to the fiduciary duties of the Trust or the Board, or to create or imply any additional fiduciary duties for the Trust or the Board. However, our Board and our Compensation Committee value the opinions of our shareholders and to the extent there is any significant vote against the named executive officer compensation as disclosed in this proxy statement, we will consider our shareholders' concerns and the Compensation Committee will evaluate whether any actions are necessary to address those concerns.

The Board of Trustees recommends a vote FOR approval of the advisory vote to approve the compensation of the Trust's named executive officers as described in the Compensation Discussion and Analysis, the compensation tables, and the related disclosures contained on pages 14 to 40 of this proxy statement.

PROPOSAL 3—ADVISORY VOTE REGARDING THE FREQUENCY OF VOTING ON THE COMPENSATION OF THE TRUST'S NAMED EXECUTIVE OFFICERS

At least once every six years, the Trust is required to provide shareholders an advisory vote on the frequency with which the Trust's shareholders shall have the advisory vote on executive compensation provided for in Proposal 2 above. The last time the shareholders voted on frequency was in 2011, and thus the Trust is providing shareholders the opportunity to again vote on frequency this year.

Specifically, the Trust is asking whether the advisory vote on executive compensation should occur every year, every two years, or every three years. The Trust currently submits advisory votes on executive compensation to shareholders on an annual basis, and the Trust continues to believe that, of the three choices, submitting such votes every year remains preferable. Thus, the Trust asks that you support a frequency period of every "1 year" for future advisory shareholder votes on the compensation of our named executive officers. Shareholders are being asked to vote on the following resolution:

The Trust believes that continuing the annual shareholder vote will enhance shareholder communication by providing a clear, simple means for the Trust to obtain information on investor sentiment about our executive compensation philosophy, and will be the most effective timeframe to engage with shareholders to understand and respond to the vote results.

As with your vote on Proposal 2 above, your vote on this Proposal 3 is advisory, and therefore not binding on the Trust, the Compensation Committee, or our Board. The vote will not be construed to create or imply any change to the fiduciary duties of the Trust or the Board, or to create or imply any additional fiduciary duties for the Trust or the Board. However, our Board and our Compensation Committee value the opinions of our shareholders and to the extent there is any significant vote for one frequency over the other options, we will consider our shareholders' concerns and the Board will evaluate any appropriate next steps.

The Board of Trustees recommends that shareholders vote for a frequency of "1 year" for future advisory shareholder votes on compensation of our named executive officers.

Our Compensation Discussion and Analysis addresses the compensation paid or awarded to our executive officers listed in the Summary Compensation Table that immediately follows this discussion. We refer to these executive officers as our "named executive officers" or as our "NEOs."

This Compensation Discussion and Analysis describes the methodology and results of the compensation program for our NEOs for 2016. Beginning in 2016, our compensation program was modified in certain respects from prior years, and where appropriate, this Compensation Discussion and Analysis also describes the impact of grants made in 2014 and 2015 under the compensation program as structured in those years.

In order to deliver our best results to our shareholders, we must attract, retain and motivate superior talent. Our compensation programs are designed to link executive rewards to financial, operating and strategic results. This pay for performance structure ensures that the financial interests of our executives are aligned with those of our shareholders. As is shown below, the majority of each executive's pay, including 60% of our CEO's target pay, is tied directly to the achievement of objective, predetermined performance goals.

Over the course of 2015, the Compensation Committee engaged in a detailed review of our compensation programs in order to:

At its March 16, 2016 meeting, the Compensation Committee implemented a number of changes to the compensation programs across our entire organization to better align all of our employees with

our overall performance as a company. For our NEOs, the changes, effective beginning in 2016, included:

Change beginning in 2016		Rationale

Incorporate additional measures of corporate performance—Same Store NOI Growth, Strategic Objectives—to the determination of the annual bonus		While the Compensation Committee has, and will continue to have, discretion to adjust awards based on its assessment of management's performance, the Committee had traditionally relied on Funds from Operations per share (FFO) as the measure to determine annual bonuses. The Committee believes that the use of multiple measures of corporate performance better reflects competitive practice as well as the nature of our multi-faceted business. The Committee also believes that the use of additional measures will create increased focus on key issues and greater clarity for employees and shareholders.
Rebalance the annual long-term incentive awards to a mix of performance-based share units (65%) and time-based share units (35%); remove stock options from the annual grant		Although we view options as being performance-based and aligned with shareholder value creation, our use of options to deliver standard LTI had fallen out of competitive practice.
Focus the measurement of performance on three-year relative TSR; remove the annual measure of FFO from the determination of long-term incentive awards		FFO is a critical measure of our success and is an important factor in the annual bonus calculation. Although the FFO Portion of the awards vested over time, the single-year performance period replicated the annual bonus program.
Pay dividends only on shares that are ultimately earned, rather than on the Target grant		By paying based on actual performance, whether below or above Target, this design reflects proper alignment between pay and performance. It also reflects current best practice.
Limit the portion of the annual bonus that can be converted to shares at a premium		While beneficial to encouraging share ownership across our entire employee population, providing employees the ability to convert the entire cash bonus award to shares at a 20% premium created the potential for above-market compensation. It is also not a typical practice among our peers.

The principal objective of our annual incentive program is to provide an incentive to achieve annual measures of financial, operating, strategic and individual performance. In setting the target level of incentive compensation opportunity, we consider competitive factors, including target total cash compensation of peers.

For performance in 2016, each NEO was eligible for a cash bonus award as defined below:

(1): The Threshold is not a guaranteed payment. The bonus would be $0 for performance below the Threshold, subject to Committee discretion.
(2): This 2016 figure reflects a reduction from the previous Maximum opportunity of 300% for the CEO.
(3): Mr. Papa joined the Company on June 1, 2016. He was eligible to participate in the Company's annual bonus plan for executive officers, which currently offers a target bonus of 85% of annual base salary for Mr. Papa's position, subject to the achievement of the Company's goal for FFO to fund the overall bonus pool and then a review of the Company's performance against certain financial metrics and goals as well as the executive's performance against goals established at the beginning of each year for such executive. For 2016, Mr. Papa's minimum bonus was guaranteed at Target on a full year basis, for an amount of $386,750.

The determination of the actual bonus awards to be earned for 2016 performance was based on multiple predetermined factors. As the first step, the Compensation Committee considered the Company's achievement of its FFO as against a pre-determined goal in order to fund the bonus pool. If the requisite FFO goal is satisfied and thus the potential bonus pool is fully funded, the Committee then will assess performance of the following measures in the following weightings and then apply its discretion based on these factors below as well as other corporate measures:

All NEOs share the same Corporate MBOs. For 2016, these MBOs emphasized the execution of our strategic plan. The specific individual performance goals for each NEO other than the Chief Executive Officer were recommended to the Committee by the Chief Executive Officer, and were reviewed and approved by the Committee. The individual performance goals for the Chief Executive Officer were established by the Committee. The Committee then determined the portion of the award to pay for the achievement of these MBOs and individual goals.

We achieved performance between our target and maximum FFO goals for 2016, as adjusted by the Committee to account for significant capital events. Accordingly, cash bonus awards for that component were paid at a level between the target and maximum bonus levels. This resulted in the Company performance component of the bonus being equal to 205% of the target bonus for the Chief Executive Officer and 170% of the target bonus for NEOs other than the Chief Executive Officer. Payments made for the Same Store NOI Growth component and for the Corporate MBOs component were at maximum level based on the Company's performance of those goals. Payments for the

individual goal component of each NEO's bonus varied depending on the Committee's assessment of that officer's achievement of his individual goals that were approved by the Committee in early 2016.

Beginning in 2016, the annual equity award consists of two components: 65% of the award is eligible to be earned following a three-year period based on how the Company's TSR performance compared to that of its Peer Group over that same period, and 35% of the award is eligible to cliff vest at the end of three years based on continued employment. We believe this new structure provides close alignment between earned compensation and shareholder value and reflects peer practices. Prior to 2016, our long-term equity incentive program was focused on achievement of FFO goals, share price and dividend growth, and outperformance against our peers in delivering shareholder return. Options and the use of a single-year FFO measurement were eliminated from our long-term equity incentive grant structure for 2016.

At the Committee's March 16, 2016, meeting, the Committee made awards under the Executive Officer LTI Program (LTI) for 2016 consistent with the new metrics and procedures adopted by the Committee as described above for 2016. Then, when Mr. Papa joined the Company on June 1, 2016, he received an LTI award equal to 145% of his annual base salary, subject to adjustment based on Company performance.

(1): The restricted shares constituting the Time-Vested Portion are eligible to vest on the third anniversary of the grant date (except for Mr. Papa's award, which is eligible to vest in equal installments on the first three anniversaries of the grant date), assuming the employee continues to be employed by the Company on the date, with vesting on death, Disability (as defined in the Share Incentive Plan) or (subject to age and years of service) retirement, in accordance with the grant agreements. Dividends are paid currently over the course of the vesting period.
(2): The RSUs constituting the TSR Portion are eligible to vest at the end of a three-year performance period (for the 2016 grants, that is 1/1/16 - 12/31/18) depending on Liberty's TSR performance relative to the TSR performance of the companies comprising our Peer Group, based on the following formula: 0% of the target shares will be earned if performance is below threshold (25^th percentile among our Peer Group); 50% of the target shares will be earned if performance is at threshold; 100% of the target shares will be earned if performance is at target (50^th percentile among our Peer Group); and 272% of the target shares will be earned by the CEO and 200% of the target shares will be earned by the other NEOs if performance is at or above maximum (75^th percentile among our Peer Group); results will be interpolated for TSR results falling between threshold and target or between target and maximum. Dividends are reinvested during the vesting period but will be paid at the end of the performance period only with respect to the shares actually earned based on performance.
(3): Mr. Alburger retired on December 31, 2016.
(4): Mr. Papa started with the Company on June 1, 2016.

At the Committee's February 27, 2017 meeting, the Committee made awards under the Executive Officer LTI Program for 2017 consistent with the same metrics and procedures adopted by the Committee as described above for 2016. The Awards consisted of the following:

At its February 27, 2017 meeting, the Committee awarded each of Messrs. Hagan and Fala a grant of 3,879 restricted Common Shares under the Share Incentive Plan. The awards were made in recognition of the efforts of Messrs. Hagan and Fala in executing the Company's 2016 property dispositions and to enhance the Company's ability to retain their services. These awards will vest on February 27, 2019, provided that on that date the recipient continues to be employed by, or is in the service of, the Company. The shares will also vest upon the death or Disability (as defined in the Share Incentive Plan) of the recipient should it occur prior to the date described in the preceding sentence. Dividends will be paid currently on the full amount of the shares, without regard to vesting, from the date of grant.

At its February 27, 2017 meeting, the Committee also reviewed the terms of a March 16, 2012 retention award of 57,870 restricted shares made to Mr. Hankowsky, which by its terms would vest on March 16, 2017, provided that (a) Mr. Hankowsky continues to be employed by, or is in the service of, the Company on that date, and (b) base rents of the Company as of December 31, 2016 from industrial properties are greater than 50% of the Company's overall base rents. The Committee has determined that the conditions to the vesting of these restricted shares were satisfied, and that therefore these restricted shares together with 17,628 shares consisting of accrued dividends thereon since the grant of the award have fully vested.

The Compensation Committee annually reviews in detail all elements of our compensation program to ensure their alignment with our philosophy and rigorous corporate governance practices.

As is its practice, the Committee established the 2016 performance goals early in 2016 and reviewed progress with respect to the applicable performance metrics regularly throughout 2016 and early in 2017. The final compensation determinations were made at a February 27, 2017 meeting, when the Committee approved 2016 bonus awards and vesting of long-term incentive awards. At the meeting, the Committee also set base salaries and targets for annual and long-term incentive awards for 2017, established 2017 performance goals and granted 2017 long-term incentive awards.

The compensation paid or awarded to our NEOs for 2016 is designed to meet the following objectives:

The Committee met seven times during 2016, including twice by teleconference, to review, evaluate and determine compensation issues. The members of the Committee are professionals with substantial executive experience. Additionally, in assessing competitive compensation and performance incentives, the Committee relied on data and advice provided to it by its independent compensation consultant, Pay Governance LLC.

The compensation consultant provides data and advice to the Committee on a regular basis. The compensation consultant developed competitive compensation levels for seasoned executives with responsibilities similar to those of our NEOs, using comparative industry data derived from the NAREIT Compensation Survey and proxy data from the Peer Group companies. We believe that data regarding this Peer Group are useful with regard to an assessment of compensation for our NEOs because they reflect industry practices and provide comparisons as to individual positions. The REITs that comprise the Peer Group are generally those that appear in the NAREIT Index as either "Industrial," "Office" or "Diversified" and fit within an appropriate range of market capitalization relevant to the Company.

Our Peer Group used to develop competitive benchmarks to assist the Committee in determining pay for 2016 consisted of the following companies:

The Committee has generally focused on the median of the Peer Group as a reference point for setting target compensation. The Committee uses its judgment after consultation with its independent compensation consultant to determine appropriate compensation for each NEO, taking into account the Peer Group data and the unique responsibilities and attributes of each NEO. The ultimate compensation decisions of the Committee are guided by competitive practice, individual role and performance, performance of the Company and internal equity.

The Committee regularly asks its independent compensation consultant to analyze the historical pay and performance alignment for the Company's NEOs. Such an analysis was conducted in 2016 and resulted in the conclusion of the Committee's consultant that our one-year (2015) and three-year (2013-2015) NEO pay and TSR performance were aligned. The realizable pay of our CEO and the average realizable pay of the other NEOs were all between the 27th percentile and the 53^rd percentile of the applicable Peer Group for both the one-year period and the three-year period under review. The Company's one-year TSR and one-year FFO per share growth were at the 43^rd percentile and the 31^st percentile, respectively, among the applicable Peer Group, and the Company's three-year TSR and three-year FFO per share growth were at the 11^th percentile and the 32^nd percentile among the applicable Peer Group.

Base salaries are set by the Compensation Committee and are designed to be competitive with the salaries paid by Peer Group companies. Historically, changes in individual base salaries have been based in part on the Committee's review of the report prepared by the independent compensation consultant, which includes a review of Peer Group compensation data, and on the Committee's review of the individual's responsibility, experience and performance, and increases in base salary being provided to our employee population generally. Base salaries are reviewed for adjustment annually.

The salaries of our NEOs for 2017, and comparison with their salaries for 2016, are set forth in the following table:


Name	2016 Salary		2017 Salary		Percentage Increase
William P. Hankowsky	$	730,000		$	751,900	3	%
Christopher J. Papa	$	455,000	(1)	$	468,650	3	%
Michael T. Hagan	$	407,000		$	423,280	4	%
Herman C. Fala	$	382,000		$	393,460	3	%

The principal objective of our annual incentive program is to provide an incentive tied to annual measures of financial, operating, strategic and individual performance. In setting the target level of incentive compensation opportunity, the Committee considers competitive factors, including target total cash compensation of peers.

For performance in 2016, each NEO was eligible for a cash bonus award as defined below:

The determination of the actual bonus awards to be earned for 2016 performance was based on multiple factors. As the first step, the Compensation Committee considered the Company's achievement of its FFO as against a pre-determined goal in order to fund the bonus pool. The requisite FFO goal was satisfied and thus the potential bonus pool was fully funded.

The second step required the Compensation Committee to assess performance of the following measures in the following weightings and then apply its discretion based on these factors below as well as other corporate measures:

With respect to our most significant goal, FFO per share, our 2016 goals were as follows: Threshold—$2.35; Target—$2.45; Maximum—$2.55; all subject to adjustment by the Committee for nonrecurring capital events. During 2016 the Company extinguished senior unsecured indebtedness in the amount of approximately $700 million, resulting in debt extinguishment losses of approximately $27.1 million, and through an unconsolidated joint venture realized debt forgiveness income of approximately $4.2 million in connection with the transfer of certain properties to the lenders in satisfaction of secured debt. The Committee determined that the FFO per share figure to govern 2016 compensation decisions should be adjusted to eliminate the impact of these two capital events, and thus concluded that the Company's actual FFO result of $2.37 per share should be adjusted to $2.52 per share, which falls between target and maximum of the range set by the Committee at the beginning of 2016.

As a result of the FFO performance, payments to the NEOs were made with respect to the FFO goal in an amount which reflected performance between the target and the maximum bonus level. This resulted in a bonus for this performance component equal to 205% of the target bonus for the CEO and 170% of the target bonus for the other NEOs.

With respect to Same Store NOI Growth, our 2016 goals were as follows: Threshold—0%; Target—1%; Maximum—2%. Our actual result was 2.8%, which exceeded the Maximum goal, resulting in a payout at the maximum level for this performance component of the bonus.

Our corporate MBOs for 2016 included the following: execute the disposition of $1.2 billion of non-core suburban office and flex properties; exceed our Core NOI target; and design and implement a realigned organizational structure for the Company reflective of the repositioning of our portfolio and geographic footprint. The Committee concluded that these goals were all met or surpassed in 2016, resulting in a payout at the maximum level for this performance component of the bonuses.

Payments made for each NEO's achievement of his MBO portion of his annual bonus varied depending on the level of such NEO's achievement of his individual stated goals.

Based on the above methodology, the Committee has determined the dollar amounts of annual bonus awards for 2016 (shown together with the target bonus amount) are as follows:

Consistent with a long-standing policy adopted by the Committee for all U.S.-based, bonus-eligible employees, our NEOs have the option of electing to receive common shares, with sale restrictions, in lieu of a cash bonus awarded to them, at the rate of shares equal to 120% of the cash value of the portion of the bonus (not to exceed $50,000) for which common shares are substituted, less applicable

withholding tax. These shares encourage share ownership and further align employee and shareholder interest. Dividends are paid on common shares issued pursuant to such awards, and restrictions on sale related to such awards will expire on February 27, 2018.

The annual bonus award payments are reflected in two separate columns of the Summary Compensation Table. The portion of the payment taken by the NEO in cash appears in the "Non-Equity Incentive Plan Compensation" column, while the portion which the NEO elected to take in common shares appears in the "Share Awards" column.

Since 2008 the Committee has operated under the Liberty Property Trust Long-Term Incentive Program (the "Long-Term Incentive Plan"). Within that Plan, the Company's long-term incentive ("LTI") program for NEOs (the "Executive Officer LTI Program") has the purpose of enhancing and refining the performance incentives provided to these officers. Under this program, each NEO is eligible to receive an LTI grant with an award value that is a targeted percentage of salary, subject to adjustment based on performance.

Beginning with 2016, we modified the program in a manner that we believe provides close alignment between earned compensation and shareholder value, as well as close alignment to the practices of our peers. Thus, for 2016, the annual equity award consisted of two components: 65% of the award is eligible to be earned following a three-year period based on how the Company's TSR performance compared to that of its Peer Group over that same period, and 35% of the award is eligible to cliff vest at the end of three years based on continued employment (except for Mr. Papa's award, which is eligible to vest in equal installments on the first three anniversaries of the grant date).

In 2015 and 2014, the Executive Officer LTI Program provided for annual awards in a target amount, divided in equal thirds as follows:

Under the Executive Officer LTI Program for 2014 and 2015, the Compensation Committee adopted a schedule of performance goals for the RSU portions of each Award, defining the threshold and maximum at which the actual FFO Portion and TSR Portion may be earned, in relation to the specified target levels. Based on the Company's actual performance over the Award Period, the RSU portion of the Award to be earned by the NEO can fall within the following ranges, although the

Compensation Committee retains discretion to reduce the Award from the prescribed level as it deems fit:

With respect to the 2014 and 2015 awards, although performance against the FFO Portion was determined, and thus "earned," annually over the Award Period, the FFO Portion is not payable until the end of the three-year Award Period. The TSR Portion for those years is measured over the entire three-year Award Period. If the recipient of the Award terminates by reason of death, Disability (as defined in the Share Incentive Plan) or (subject to scaled vesting based on age and years of service) retirement prior to the end of the Award Period, units would be payable at the end of the Award Period based on actual attainment within each Performance Period, and would not be pro-rated for short service. The Executive Officer LTI Program also includes several common restrictive covenants and other provisions, subject to the Compensation Committee's discretion, that would trigger forfeiture of an Award.

When the Trust's common shares are issued with respect to the Awards they underlie, they will be issued under the Share Incentive Plan, and will generally be subject to the terms and conditions of that plan.

The year 2016 was the final performance year of the 2014 award under the Executive Officer LTI Program and as a result the Committee was required to review the Company's three-year TSR performance under the TSR Portion of the award made in 2014 as well as evaluate the Company's performance in 2016 to determine the amount earned under the relevant one-third of the FFO Portion of the awards made in 2014 and 2015.

As to the FFO Portion, the NEOs were determined to have earned between the target amount and the maximum amount in 2016 for the FFO Portion of the awards made in 2014 and 2015, resulting in a payout of 220% of the target amount of this portion of the 2014 and 2015 awards to the Chief Executive Officer and 170% of the target amount of this portion of the 2014 and 2015 awards to the NEOs other than the Chief Executive Officer.

With respect to the TSR Portion of the 2014 award, our three-year TSR during 2014-2016 was below the threshold level (25th percentile relative to the Peer Group that was in place in 2014 for this calculation). Accordingly, the Committee determined that there would be no payout for the TSR portion of the 2014 award.

As a result of these determinations, the awards (listed together with prior awards during the Award Period) are set forth below.

Through the Record Date, Mr. Hankowsky also accrued an aggregate of 9,385 restricted stock units through the reinvestment of dividends accrued on the restricted stock units awarded. This dividend amount includes dividends accrued at Target on the unvested units outstanding for the FFO Portion of the 2014 and 2015 awards and the TSR portion of the 2014 award, all of which are shown in the table above, as well as the TSR Portion of the 2015 award, which is not shown in the table above. Of this amount, however, 2,494 restricted stock units consisting of dividends that had been accrued on the TSR portion of the 2014 award were subsequently forfeited on February 27, 2017, as a result of the determination by the Committee that no shares were earned with respect to the TSR Portion of the 2014 award.

Through the Record Date, Mr. Alburger also accrued an aggregate of 3,558 restricted stock units through the reinvestment of dividends accrued on the restricted stock units awarded. This dividend amount includes dividends accrued at Target on the unvested units outstanding for the FFO Portion of the 2014 and 2015 awards and the TSR portion of the 2014 award, all of which are shown in the table above, as well as the TSR Portion of the 2015 award, which is not shown in the table above. Of this amount, however, 993 restricted stock units consisting of dividends that had been accrued on the TSR portion of the 2014 award were subsequently forfeited on February 27, 2017, as a result of the determination by the Committee that no shares were earned with respect to the TSR Portion of the 2014 award.

Through the Record Date, Mr. Hagan also accrued an aggregate of 2,969 restricted stock units through the reinvestment of dividends accrued on the restricted stock units awarded. This dividend amount includes dividends accrued at Target on the unvested units outstanding for the FFO Portion of the 2014 and 2015 awards and the TSR portion of the 2014 award, all of which are shown in the table above, as well as the TSR Portion of the 2015 award, which is not shown in the table above. Of this amount, however, 804 restricted stock units consisting of dividends that had been accrued on the TSR portion of the 2014 award were subsequently forfeited on February 27, 2017, as a result of the determination by the Committee that no shares were earned with respect to the TSR Portion of the 2014 award.

Through the Record Date, Mr. Fala also accrued an aggregate of 2,885 restricted stock units through the reinvestment of dividends accrued on the restricted stock units awarded. This dividend amount includes dividends accrued at Target on the unvested units outstanding for the FFO Portion of the 2014 and 2015 awards and the TSR portion of the 2014 award, all of which are shown in the table above, as well as the TSR Portion of the 2015 award, which is not shown in the table above. Of this amount, however, 803 restricted stock units consisting of dividends that had been accrued on the TSR portion of the 2014 award were subsequently forfeited on February 27, 2017, as a result of the determination by the Committee that no shares were earned with respect to the TSR Portion of the 2014 award.

In view of the fact that 2016 was the final year of the Award Period for the 2014 LTI Awards to our NEOs, the following table presents a recap of the LTI Awards made to the NEOs in 2014, including the aggregate number of shares earned with respect to the FFO and TSR Portions of the RSU Awards, and the current status of the options granted in 2014, each as of February 27, 2017, the date on which the Committee determined the payout of the last component of these Awards:

The tables that follow this Compensation Discussion and Analysis set forth the compensation that our NEOs were paid in 2016. In certain cases, however, decisions regarding compensation for 2016

services performed by our NEOs were made in February 2017. In order to provide additional clarification on all compensation paid in consideration of 2016 performance, we are providing the following table. It should not be read as a replacement of the tables appearing following this Compensation Discussion and Analysis, but as a supplement thereto. The amounts reflected in this table include:

(a): Consistent with a policy adopted by the Compensation Committee for all employees, our NEOs have the option of taking common shares in lieu of a cash bonus awarded to them at the rate of shares equal to 120% of the cash value of the portion of the bonus (not to exceed $50,000) for which common shares are substituted, less applicable withholding tax. Messrs. Papa, Fala and Alburger exercised this option as to all or a portion of their entire annual bonuses and were awarded 1,066, 1,021 and 1,008 common shares, respectively.
(b): Includes (i) $6,858, $621, $2,322, $6,858 and $6,858 paid by the Company to purchase term life insurance policies for each of Messrs. Hankowsky, Papa, Hagan, Fala and Alburger; (ii) $500 paid to each NEO as a holiday bonus with the exception of Mr. Hankowsky; this amount is paid to each employee of the Company; (iii) $722 compensation for Mr. Hankowsky related to the grant of 15 common shares in recognition of his 15th anniversary of employment; and (iv) $40,514, $16,611, $17,468, $8,617 and $18,889 paid by the Company for dividends on restricted share awards for each of Messrs. Hankowsky, Papa, Hagan, Fala and Alburger. Includes relocation and housing allowance of $221,031 for Mr. Papa and $275,662 vacation payout for Mr. Alburger.
(c): Includes dividends and multiplier on RSUs through February 27, 2017.
(d): Mr. Papa joined the Company on June 1, 2016. This salary figure is the annualized amount.

In 2016, we followed practices for the grant of share-based awards consistent with the manner in which we have historically granted such awards. Among other things, these practices encompass the following principles:

We have a management severance plan for a group of senior officers, including our NEOs. Various aspects of this plan are described under "Payments upon Termination Events, Including Following a Change of Control." The management severance plan provides for payments and other benefits to each of the NEOs if the executive's employment is terminated without cause or if the executive terminates employment for "good reason" within six months before or two years after a change of control.

Under Section 162(m) of the Code, a publicly-held corporation may not deduct more than $1 million in a taxable year for certain forms of compensation made to the chief executive officer and certain other officers listed on the Summary Compensation Table. Our policy is to seek to preserve the federal income tax deductibility of compensation paid to our executives, and our annual bonus and equity awards have generally been structured to preserve deductibility under Section 162(m). Nevertheless, we retain the flexibility to authorize compensation that may not be deductible if it is in the best interests of our company. We believe that substantially all of the compensation paid to our executives for 2016 was deductible.

Although our management severance plan previously provided for the payment to certain NEOs of a "gross-up" payment with respect to excise taxes and other taxes that might be payable as a result of payments under that plan, this feature of our plan was eliminated on September 30, 2016. As a result, no excise tax "gross-up" payments are payable to any of our officers.

Role of Executive Officers in Determining Executive Compensation for Named Executive Officers

In connection with our 2016 compensation, Pay Governance LLC provided data and Ms. Hosansky, the Company's Senior Vice President—Human Resources, provided general support to the Compensation Committee to assist it in determining compensation levels. Mr. Hankowsky made recommendations as to the other NEOs, but not as to his own compensation. While the Compensation Committee utilized this information, and valued Mr. Hankowsky's observations with regard to other NEOs, the ultimate decisions regarding executive compensation were made by the Compensation Committee.

Consistent with an emphasis on higher standards of corporate governance, we believe that the investment community values share ownership by senior management and that, by holding an equity position in the Trust, officers demonstrate their commitment to and belief in the long-term profitability of the Company. Accordingly, the Board believes that ownership of Company shares by officers should be encouraged, and has established ownership guidelines applicable to the Company's officers at the Senior Vice President level and above.

The policy states that each covered officer should seek to acquire and maintain a level of ownership of Company common shares (determined based on the fair market value of such shares from time to time as a multiple of the officer's base salary) as follows: Chief Executive Officer: 6x; Chief Financial Officer, Chief Investment Officer and General Counsel: 3x; and Senior Vice Presidents: 1x.

The policy stipulates that the covered officers should work toward achieving these levels of ownership with the objective of meeting the requirements within five years of becoming subject to these requirements. Once a covered officer has achieved the targeted level of share ownership, the policy states that he or she (i) should maintain at least that level of ownership for the duration of his or her tenure with the Company and (ii) should, within three-years after receiving an increase in salary or a

promotion, seek to achieve the resulting greater target level of ownership. All senior officers are in compliance with this policy.

The policy recognizes the following sources of share ownership for purposes of determining whether the above ownership target is satisfied:

For purposes of determining whether the ownership target is satisfied, shares underlying outstanding options are not included.

The policy further mandates that until such time as a covered officer has attained the applicable target ownership level, he or she must retain common shares obtained as a result of a share award, unless the Board otherwise permits.

The Board believes that trustees should be shareholders and have a financial stake in the Company. In furtherance of this belief, non-management trustees are paid a portion of their annual fees in the Trust's common shares.

Additionally, the trustees are expected to own an amount of Company common shares equal in value to 6x the annual cash retainer paid to trustees. Our policy stipulates that the trustees should work toward achieving these levels of ownership with the objective of meeting the requirements within five years of becoming a trustee. All trustees are in compliance with this policy.

In addition to the components noted above, our compensation program may also include various benefits, such as health insurance plans and pension, profit sharing and retirement plans in which substantially all of the Company's employees participate. At the present time, the only plans in effect are health, dental, life and disability insurance plans, a 401(k) plan, a flexible spending insurance program, the generally applicable severance plan for all employees, an employee share purchase plan, other voluntary benefits programs and the severance plan for certain senior officers of the Company in the event of a change of control, as described under "Management Severance Plan." While we generally limit the perquisites received by our executive officers, we did provide Mr. Papa with certain relocation benefits and a housing allowance in 2016 in connection with the commencement of his employment as our Chief Financial Officer.

The following table shows, for the years ended December 31, 2016, 2015 and 2014, the compensation paid or accrued by the Company and its subsidiaries, including the Operating Partnership, to our named executive officers.

A portion of the amounts shown in this column reflects the elections by Messrs. Hankowsky, Papa, Hagan, Fala and Alburger, consistent with a policy adopted by the Compensation Committee with respect to employee annual performance non-equity incentive compensation, which we sometimes refer to as annual bonus, to receive common shares in lieu of cash for all or part of their annual bonus compensation for 2016, 2015 or 2014. By making such elections, these individuals received shares equal to 120% of the cash value of such bonus or portion thereof, less applicable withholding tax (the "Bonus Value"). Each executive received the number of common shares able to be purchased with the dollar amount of the Bonus Value based on the closing price of the common shares of the Company on the New York Stock Exchange on March 16, 2017 ($38.25) for bonuses included in 2016 compensation; the closing price of the common shares of the Company on the New York Stock Exchange on March 16, 2016 ($32.06) for bonuses included in 2015 compensation or March 16, 2015 ($35.18) for bonuses included in 2014 compensation. Pursuant to these elections, Messrs. Papa, Fala and Alburger were awarded 1,066, 1,021 and 1,008 common shares, respectively, as 2016 compensation, and Messrs. Hankowsky, Alburger, Hagan and Fala were awarded 8,578, 17,872, 14,339 and 10,553 common shares, respectively, as 2015 compensation, and 8,803, 8,339, 5,697 and 2,764 common shares, respectively, as 2014 compensation. Dividends will be paid on the common shares issued pursuant to such awards. The contractual restrictions on sale related to such awards will expire on February 27, 2018 for the awards made as 2016 compensation and expired on March 16, 2017 for the awards made as 2015 compensation and March 16, 2016 for the awards made as 2014 compensation. Beginning with bonuses awarded in March 2017 for performance in 2016, this policy has been modified to limit to $50,000 the amount of an employee's bonus that is eligible for the 20% premium.

Mr. Papa was awarded 10,869 restricted shares upon the commencement of his employment with us as a "make-whole" grant to compensate him for the value of unvested equity forfeited from his prior employer in excess of the value of his 2016 LTI grant from us. This stock vests on approximately the same vesting schedule of the forfeited unvested restricted

stock and options of the prior employer, such that 51% vested on December 20, 2016, 33% will vest on December 20, 2017 and the remainder will vest on December 20, 2018.

(1): March 16, 2016 represents the date on which the Committee (i) set the range of potential annual bonus awards for 2016 performance by named executive officers, and (ii) made Awards under the Executive Officer Plan to the named executive officers for 2015. These Awards were determined in reference to the performance measures established by the Committee at its March 16, 2015 meeting. At the March 16, 2016 meeting, the Committee also established the range of potential Awards under the Executive Officer Plan for 2016 performance.
(2): This award reflects the range of potential annual bonus available to be earned by the named executive officer for 2016. The actual amounts earned for 2016 pursuant to the annual bonus program are set forth in the Summary Compensation Table under "Non-Equity Incentive Plan Compensation" (or, where the named executive officer chose to take all or a portion of

his annual bonus in the form of restricted shares, under "Share Awards"), and are also set forth in the table below. Each named executive officer's annual bonus is a function of salary, with each named executive officer able to earn a specified target percentage of his salary (115% for chief executive officer and 85% for chief financial officer, chief investment officer and chief legal officer), subject to adjustment based on performance. The base amount of the bonus was calculated in accordance with the two step process discussed under "Compensation Discussion and Analysis—Annual Bonus Program."

The dollar amounts of the actual awards under the annual bonus program for 2016 performance, determined by the Committee at its February 27, 2017 meeting, were as follows:

(1)

Value is calculated by multiplying the number of shares subject to vesting by $39.50, the closing price of the common shares on the New York Stock Exchange on December 30, 2016.

(2)

Represents options granted on March 17, 2014 with respect to the fiscal year ended December 31, 2013. Such options became exercisable up to 20% after one year and 50% after two years, and will become exercisable up to 100% after three years.

(3)

Represents options granted on March 16, 2015 with respect to the fiscal year ended December 31, 2014. Such options became exercisable up to 20% after one year, and will become exercisable up to 50% after two years and 100% after three years.

(4)

These shares will vest as follows:

•

8,578 shares on March 16, 2017 (shares granted on March 16, 2016 pursuant to the Company's bonus program, under which the executive can elect to receive restricted common shares, subject to a one year holding period, in lieu of a portion of his annual bonus);

•

6,441 shares, being the unvested portion of an award of 10,735 shares granted on May 17, 2014, vesting in equal installments on the first five anniversaries of the date of grant; and

•

19,127 shares, being the unvested award of shares granted on March 16, 2016 eligible to vest on the third anniversary of the date of grant.

Of the remaining shares, 74,614 will vest on March 16, 2017. These shares consist of 57,870 shares granted under the Share Incentive Plan on March 16, 2012 as a retention award, which by its terms vested on March 16, 2017, as well as 16,744 shares accrued in connection with the Company's quarterly dividend since the date of grant. The purpose of the award was to act as an incentive to encourage the achievement of significant operational goals, as well as to enhance the Company's ability to retain Mr. Hankowsky's services. Dividends were paid on the full amount of the shares, without regard to vesting, from the date of grant, and are automatically reinvested, through the Company's Dividend Reinvestment and Share Purchase Plan, in common shares, which are subject to the restrictions described above.

Additionally, represents 32,801 earned RSUs. See footnote (9).

The number of shares acquired and the value realized on the exercise of options by and the vesting of share awards for each of the named executive officers during 2016 are set forth in the following table.

The following table provides information regarding our compensation plans under which our equity securities are authorized for issuance. The information provided is as of December 31, 2016.

The Company has a management severance plan for a group of senior officers of the Company, including Messrs. Hankowsky, Papa, Hagan and Fala. Prior to his retirement on December 31, 2016, Mr. Alburger was also covered by the management severance plan. The management severance plan applies in the event of terminations following a change of control, as defined in the plan and described below. Pursuant to a letter agreement between Mr. Papa and the Company entered into in connection with Mr. Papa's employment, he is also entitled to certain payments in the case of certain terminations as described in that letter. For other termination events, the named executive officers are covered by the Company's termination policies applicable generally to all employees.

The tables below reflect the amounts that would be payable to the NEOs upon various termination events, including pursuant to the management severance plan. These tables show the amount of compensation payable to each of the named executive officers in the event of termination of such

executive's employment, in each of the following cases: termination by the Company not for Cause, retirement, in the event of death or disability and, as covered by the management severance plan, in connection with a change of control. The amounts indicated are based on the assumption that the termination occurred as of December 30, 2016, on which date the closing price of the common shares on the New York Stock Exchange was $39.50. Actual amounts payable would vary based on the date of the NEO's termination and can only be finally determined at that time.

If the employment of an NEO is terminated by the Company not for cause (including such a termination in connection with a change of control), he is entitled to receive the following amounts consistent with our policies for all employees:

Under the terms of the agreements pursuant to which the NEOs have been granted their options, restricted shares and restricted share units, the vesting of unvested options, restricted shares or restricted share units at the retirement of the named executive officer is generally based upon a sliding scale taking into account the NEO's age and length of service to the Company. The following table illustrates this scale:

Age		Amount to Vest

55 - 56	10	Options and restricted shares that would have vested in accordance with their terms during the 12 month period after the named executive officer's retirement shall vest as of the date of retirement
57 - 58	8	Options and restricted shares that would have vested in accordance with their terms during the 24 month period after the named executive officer's retirement shall vest as of the date of retirement
59 - 60	6	Options and restricted shares that would have vested in accordance with their terms during the 36 month period after the named executive officer's retirement shall vest as of the date of retirement
61 - 62	4	Options and restricted shares that would have vested in accordance with their terms during the 48 month period after the named executive officer's retirement shall vest as of the date of retirement
63 - 64	2	Options and restricted shares that would have vested in accordance with their terms during the 60 month period after the named executive officer's retirement shall vest as of the date of retirement
65 or more	—	All options and restricted shares not vested at the date of retirement shall vest as of the date of retirement

In each case above, all unvested RSUs as of the date of retirement will remain eligible to be earned and vested in accordance with the applicable grant documents for the period of time after retirement as stated in each case above, notwithstanding that the NEO is no longer employed by the Company.

As of December 31, 2016, the NEOs were the following ages and had the following years of service to the Company:

The options that become exercisable upon retirement, along with any other options that were already exercisable on the date of retirement, may be exercised until the date that is 36 months after the date of retirement.

In the event of the death or disability of an NEO, all unvested options and restricted shares owned by the NEO will vest immediately, and all unvested restricted share units will remain eligible to be earned and vested in accordance with applicable grant documents, notwithstanding that the NEO is no longer employed by the Company. In the case of options, the options will remain exercisable until the date that is 36 months after the date of termination of the named executive officer's employment with the Company due to his death or disability. Upon death or disability an NEO or his representatives are also entitled to receive unused vacation pay.

Pursuant to the management severance plan, if within six months prior to a change of control or two years following a change of control an executive's employment is terminated by the Company (other than termination for cause) or the executive terminates his employment in certain circumstances defined in the agreement which constitute "good reason":

Pursuant to Section 16(a) of the Exchange Act, the Company's executive officers and trustees, and persons beneficially owning more than 10% of the common shares, are required to file with the Securities and Exchange Commission reports of their initial ownership and changes in ownership of common shares. The Company believes that during 2015, its executive officers and trustees who were required to file reports under Section 16(a) complied with such requirements in all material respects.

The following table shows the compensation paid to the members of the Trust's Board of Trustees for the year ended December 31, 2016.

PROPOSAL 4—RATIFICATION OF SELECTION OF
INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Ernst & Young LLP has audited the Trust's financial statements since the Trust's inception. The Audit Committee of the Board of Trustees has selected Ernst & Young LLP as the Trust's independent registered public accounting firm for the fiscal year ending December 31, 2017.

Representatives of Ernst & Young LLP are expected to be present at the Meeting. They will have an opportunity to make a statement if they desire to do so, and are expected to be available to respond to appropriate questions.

Ernst & Young was the Trust's independent registered public accounting firm for the fiscal years ended December 31, 2016 and 2015.

Audit Fees. Fees for audit services rendered to the Trust and the Operating Partnership by Ernst & Young LLP for the fiscal years ended December 31, 2016 and 2015 were $1,246,100 and $1,227,800, respectively. These services included (i) the audit of the Trust's and the Operating Partnership's annual financial statements and internal control over financial reporting, (ii) the reviews of the financial statements included in the Trust's and the Operating Partnership's Quarterly Reports on Form 10-Q for the quarters ended March 31, June 30, and September 30 and (iii) consents on the Trust's and the Operating Partnership's Forms S-3 and S-8.

Audit-Related Fees. Fees for audit-related services that were reasonably related to the performance of the 2016 and 2015 audits or reviews of the financial statements of the Trust and the Operating Partnership and are not reported under the preceding paragraph totaled $3,000 for each year. These fees were for attest services relating to required reporting to the United States Environmental Protection Agency.

Tax Fees. Fees billed to the Trust and the Operating Partnership by Ernst & Young LLP during 2016 and 2015 for professional services rendered for tax compliance, tax advice and tax planning totaled $285,840 and $256,375, respectively.

All Other Fees. All other fees billed to the Trust and the Operating Partnership by Ernst & Young LLP during 2016 and 2015 were for audit and tax services on certain unconsolidated joint ventures during 2016 and 2015 equaling $420,900 and $551,100, respectively. These fees were paid by the respective joint venture partnerships.

All audit, audit-related and tax services were pre-approved by the Audit Committee. The Audit and Non-Audit Services Pre-Approval Policy provides for (i) general pre-approval of certain specified services and (ii) specific pre-approval of all other permitted services, as well as proposed services exceeding pre-approved cost levels. The policy authorizes the Audit Committee to delegate pre-approval authority with respect to permitted services to one or more of its members.

For both types of pre-approval, the Audit Committee will consider whether such services are consistent with the Securities and Exchange Commission's rules on auditor independence. The Audit Committee will also consider whether the independent registered public accounting firm is best positioned to provide the most effective and efficient service, for reasons such as its familiarity with the Trust's business, people, culture, accounting systems, risk profile and other factors, and whether the service might enhance the Trust's ability to manage or control risk or improve audit quality. All such factors will be considered as a whole, and no one factor is necessarily determinative.

Shareholder ratification of the selection of Ernst & Young LLP as the Trust's independent registered public accounting firm is not required by the Trust's Bylaws or any other applicable legal

requirement. However, the Board of Trustees is submitting the selection of Ernst & Young LLP to the shareholders for ratification as a matter of good corporate practice. If the shareholders fail to ratify the selection, the Audit Committee and the Board of Trustees will reconsider whether or not to retain that firm. Even if the selection is ratified, the Board of Trustees at its discretion may direct the appointment of a different independent registered public accounting firm at any time during the year if it determines that such a change would be in the best interests of the Trust and the shareholders.

The Audit Committee has considered whether Ernst & Young LLP's provision of services other than professional services rendered for the audit and review of the Trust's annual financial statements is compatible with maintaining Ernst & Young LLP's independence, and has determined that it is so compatible.

The Board of Trustees recommends a vote FOR ratification of Ernst & Young LLP as the Trust's independent registered public accounting firm for the fiscal year ending December 31, 2017. Ratification requires the affirmative vote of a majority of all the votes cast at the Meeting.

Our Codes of Conduct for Trustees and for named executive officers mandate that officers and trustees bring promptly to the attention of our General Counsel any transaction or series of transactions that may result in a conflict of interest between that person and the Trust. Following any disclosure, our General Counsel will then review with the Chairman of our Audit Committee the relevant facts disclosed by the officer or trustee in question. After this review, the Chairman of the Audit Committee and the General Counsel determine whether the matter should be brought to the Audit Committee or the full Board of Trustees for approval. In considering any such transaction, the Audit Committee or the Board of Trustees, as the case may be, will consider various relevant factors, including, among others, the reasoning for the Trust to engage in the transaction, whether the terms of the transaction are arm's length and the overall fairness of the transaction to the Trust. If a member of the Audit Committee or the Board is involved in the transaction, he or she will not participate in any of the discussions or decisions about the transaction. The transaction must be approved in advance whenever practicable, and if not practicable, must be ratified as promptly as practicable.

The Audit Committee oversees the Trust's financial reporting process on behalf of the Board of Trustees. Management has the primary responsibility for the financial statements and the reporting process, including the systems of internal controls. The Committee is responsible for oversight of this function. In fulfilling its oversight responsibilities, the Committee reviewed and discussed with management the audited financial statements and management's assessment of internal control over financial reporting in the Annual Report on Form 10-K for the fiscal year ended December 31, 2016, including a discussion of the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments, and the clarity of disclosures in the financial statements.

The Committee reviewed with the independent registered public accounting firm, which is responsible for expressing an opinion on the conformity of those audited financial statements in accordance with U.S. generally accepted accounting principles, the firm's judgments as to the quality, not just the acceptability, of the Trust's accounting principles and such other matters as are required to be discussed with the Committee under the standards of the Public Company Accounting Oversight Board, including those required to be discussed with the Committee by Auditing Standard No. 16 adopted by the Public Company Accounting Oversight Board. The Committee has discussed with the independent registered public accounting firm the firm's independence from management and the Trust, including the matters in the written disclosures required by Independence Rule No. 3526, and has received the written disclosures and the letter from the independent registered public accounting firm required by Independence Rule No. 3526. In addition, the Committee has considered the effect of the independent registered public accounting firm's provision of non-audit services on the audit and considers such services compatible with the independent registered public accounting firm's maintenance of independence.

The Committee discussed with the Trust's internal auditors and the independent registered public accounting firm the overall scope and plans for their respective audits. The Committee pre-approved all audit and non-audit services provided by the independent registered public accounting firm in accordance with the Audit and Non-Audit Services Pre-Approval Policy adopted by the Committee. The Committee meets with the internal auditors and the independent registered public accounting firm, with and without management present, to discuss the results of their examinations, their evaluations of the Trust's internal controls, and the overall quality of the Trust's financial reporting.

The Committee also approves the compensation and annual selection of the independent registered public accounting firm, and is involved in the selection of the accounting firm's lead engagement partner on the Company's account. The Committee also considers both the accounting firm's tenure and impact of changing auditors when assessing whether to retain the current independent registered public accounting firm as its external auditor.

During 2016, management completed the documentation, testing and evaluation of the Trust's system of internal control over financial reporting in response to the requirements set forth in Section 404 of the Sarbanes-Oxley Act of 2002 and related regulations. The Committee was kept apprised of the progress of the evaluation and provided oversight and advice to management during the process. In connection with this oversight, the Committee received periodic updates provided by management and Ernst & Young LLP at each regularly scheduled Committee meeting. At the conclusion of the process, management provided the Committee with a report on the effectiveness of the Trust's internal control over financial reporting. The Committee also reviewed the report of management contained in the Trust's Annual Report on Form 10-K for the fiscal year ended December 31, 2016 filed with the Securities and Exchange Commission, as well as Ernst & Young LLP's Reports of Independent Registered Public Accounting Firm (included in the Trust's Annual Report on Form 10-K) and reports related to its audits of the consolidated financial statements and the effectiveness of internal control over financial reporting. The Committee continues to oversee

the Trust's efforts related to its internal control over financial reporting and management's preparations for the evaluation in fiscal 2017.

In reliance on the reviews and discussions referred to above, the Committee recommended to the Board of Trustees (and the Board has approved) that the audited financial statements be included in the Annual Report on Form 10-K for the year ended December 31, 2016 for filing with the Securities and Exchange Commission.

The Compensation Committee oversees the Trust's executive compensation process on behalf of the Board of Trustees. In fulfilling its oversight responsibilities, the Committee reviewed and discussed with management the Compensation Discussion and Analysis.

In reliance on the reviews and discussions referred to above, the Committee recommended to the Board of Trustees (and the Board has approved) that the Compensation Discussion and Analysis be included in this proxy statement.

None of the members of the Compensation Committee was an officer or employee of the Trust or its subsidiaries during 2016, was formerly an officer of the Trust or its subsidiaries, or had any relationship with the Trust since the beginning of 2016 that requires disclosure under applicable Securities and Exchange Commission regulations.

The Board's role in the Trust's risk oversight process includes receiving regular reports from members of senior management on areas of material risk to the Trust, including operational, financial, legal and regulatory and strategic risks. The Board also works to oversee risk through its consideration and authorization of significant matters, such as major strategic, operational and financial initiatives and its oversight of management's implementation of those initiatives.

In particular, the Audit Committee is tasked pursuant to its charter to "discuss with management the Company's major policies with respect to risk assessment and risk management." As appropriate, the Chair of the Audit Committee reports to the full Board on the activities of the Audit Committee in this regard, allowing the Audit Committee and the full Board to coordinate their risk oversight activities.

In its risk oversight capacity, the Board and the Audit Committee engage in various practices, including, without limitation:

The Audit Committee is specifically responsible for discussing the guidelines and policies that govern the process by which the Trust's exposure to risk is assessed by management. As part of this process, the Audit Committee regularly assesses risks faced by the Trust in a manner designed to identify and analyze risks to achieving the Trust's business objectives. The results of these risk assessments are then discussed with management. In addition, as one component of the Trust's anti-fraud program, the Trust, under the supervision of the Audit Committee, established a hotline available to all employees for the anonymous and confidential submission of complaints relating to any matter to encourage employees to report questionable activities directly to our senior management and the Audit Committee.

Our Compensation Committee has considered the concept of risk as it relates to our compensation program. While behavior that may result in inappropriate risk taking cannot necessarily be prevented by the structure of compensation practices, we believe that our compensation policies or practices do not create risks that are reasonably likely to have a material adverse effect on us. In our

"Compensation Discussion and Analysis," we discuss in general the compensation policies and practices that are applicable to our named executive officers. We believe that because these policies and practices, as well as the policy and practices utilized with respect to our more senior employees, incorporate variable compensation elements that focus on our overall financial performance, our individual employees are incentivized to act in furtherance of our overall corporate goals. We also have in place various operational controls, such as senior management review of significant leases and contracts, that we believe would aid in preventing the implementation of risky business arrangements.

Compensation to our executive officers and senior employees is comprised of both fixed and incentive-based elements. The fixed compensation (i.e., regular salary) provides reliable, foreseeable income that mitigates the focus of our employees on the immediate financial performance of our company or its stock price, encouraging them to make decisions in our best long-term interests. The incentive components are designed to be sensitive to both our short- and long-term performance and stock price. In combination, we believe that our compensation structures do not encourage our officers and employees to take unnecessary or excessive risks in performing their duties. Contributing to this belief is the fact that our compensation structure has been structured substantially as it is now for a number of years, with occasional minor modifications to conform to changing industry-wide best practices, and we have seen no evidence that it encourages unnecessary or excessive risk taking.

The Board, guided by the Corporate Governance and Nominating Committee, periodically monitors best practices in corporate governance, and as appropriate, considers and implements changes to the Trust's governance structure in order to reflect these best practices. As discussed below, in early 2014 this led to the Board electing a Lead Independent Trustee to supplement the leadership of the Board.

Since the Trust's inception, it has had a board leadership structure under which the Chief Executive Officer also serves as Chairman of the Board. The Trust believes that it has been well-served by this structure and that the structure facilitates strong, clear and cohesive leadership, with a single person setting the tone and having the ultimate responsibility for all of the Trust's operating and strategic functions, thus providing unified leadership and direction for the Board and executive management.

Currently, Mr. Hankowsky serves in these dual capacities, as he has since June 2003, when he was named Chairman in addition to his role as Chief Executive Officer, which he has held since January 2003. While the Board does not believe that the roles of Chairman and Chief Executive Officer must always be combined, and reserves the right to reconsider the issue as it deems appropriate, it intends to continue the current arrangement for the foreseeable future.

Early in 2014, the Board, guided by the Corporate Governance and Nominating Committee, determined that it was in the best interests of the Trust and the shareholders for the Board to name a Lead Independent Trustee and, on March 26, 2014, elected Daniel P. Garton to fulfill that role. The Board believes that a Lead Independent Trustee will help to facilitate active and effective oversight by the independent trustees of the Trust's operations and strategic initiatives, including the risks that may be attendant thereto. As set forth in the Trust's corporate governance guidelines, the specific responsibilities of the Lead Independent Trustee include:

Our Board is comprised of eight independent trustees and Mr. Hankowsky. Each of the trustees is a sophisticated and seasoned business person experienced in board processes and knowledgeable regarding matters of corporate governance, and has substantial leadership experience in his or her field.

For additional information about the backgrounds and qualifications of our directors, see "Proposal 1—Election of Trustees and Continuing Trustees."

Although the Board is of the view that trustees with longstanding tenure on the Board provide significant benefits by way of their continuity, institutional memory and experience with the business and operations of the Trust, the Board also is committed to bringing new trustees on to the Board from time to time as a way of introducing new ideas and perspectives and filling anticipated Board succession needs. Toward that end, the Corporate Governance and Nominating Committee is currently in the process of seeking one or more new trustees with the appropriate skills, experience and business acumen to complement the current composition of the Board.

The Board has conducted a review of the independence of the trustees under the standards for independence established by the New York Stock Exchange. During this review, the Board considered any transactions and relationships between a trustee or member of that trustee's immediate family and the Trust and its subsidiaries and affiliates. The Board also examined any transactions and relationships between trustees or their affiliates and members of the Trust's senior management or their affiliates. The purpose of this review was to determine whether any such relationships or transactions were inconsistent with a determination that the trustee is independent. Taking into account the review, the Board has determined that each of the trustees, other than Mr. Hankowsky, meets these standards, and is independent.

In connection with the Board's annual affirmative determination as to the independence of the members of the Board, the Board considered the following matters: The husband of trustee Katherine E. Deitze is the Chief Investment Officer of Travelers Insurance, which from time to time has held debt and equity securities of the Company. Trustee Fredric J. Tomczyk was, until his retirement on September 30, 2016, the President and CEO of TD Ameritrade Holdings Corporation. TD Bank, which owns 41% of TD Ameritrade Holdings Corporation, is one of the 15 participant lenders in Liberty's unsecured line of credit. Mr. Tomczyk was not an officer, director or shareholder of TD Bank and was not involved in its management or in its lending decisions. The Committee determined that the above circumstances do not cause Ms. Dietze or Mr. Tomczyk to fail any of the tests for independence as set forth in Rule 303A.02(b) of the New York Stock Exchange Listed Company Manual, and they did not constitute a material relationship.

The Trust has a code of conduct for all its employees, including its chief executive officer and senior financial officers, including the Trust's principal financial officer and our principal accounting officer or controller within the meaning of the Securities and Exchange Commission regulations adopted under the Sarbanes-Oxley Act of 2002. The code of conduct is posted under the "Investors" section of the Trust's web site at www.libertyproperty.com.

In addition, shareholders may request a copy of the code of conduct by directing a written request to the Vice President of Investor Relations at the address of the Trust appearing on the Notice of Annual Meeting that accompanies this proxy statement.

The Trust encourages all of the trustees to attend the annual meeting of shareholders. The 2016 Annual Meeting of Shareholders was attended by all of the trustees.

The Trust provides the opportunity for shareholders to communicate with the members of the Board. In this regard, the Board of Trustees has also adopted a process by which shareholders and other interested parties may communicate with the independent trustees or the chairperson of any of the committees of the Board of Trustees by e-mail or regular mail. Communications by e-mail should be sent to hfala@libertyproperty.com. Communications by regular mail should be sent to the attention of the Chairperson, Audit Committee; Chairperson, Compensation Committee; or Chairperson, Corporate Governance and Nominating Committee; or to the independent trustees as a group to the Lead Independent Trustee, c/o the Secretary of the Trust at the address appearing on the notice accompanying this proxy statement.

All communications received in accordance with this process will be reviewed by the Trust's management to determine whether the communication requires immediate action. Management will pass on all communications received, or a summary of such communications, to the appropriate trustee or trustees. However, management reserves the right, with the concurrence of the Lead Independent Trustee, to disregard any communication that it determines to be unduly hostile, threatening, illegal, not reasonably to relate to the Trust or its business, or to be otherwise 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.

On March 27, 2017, the Board adopted amendments to the Trust's Bylaws, effective immediately upon adoption, to provide shareholders, in addition to the Board, with the power to alter, amend or repeal any provision of the Bylaws and to make new Bylaw provisions, in each case by the affirmative vote of a majority of all the votes outstanding and entitled to be cast on the matter.

Shareholder nominations for election to the Board of Trustees should be sent to the attention of the Secretary of the Trust at the address appearing on the notice accompanying this proxy statement, describe the nominee's qualifications and be accompanied by the nominee's written statement of willingness and affirmative desire to serve representing the interest of all shareholders. Shareholders may also make nominations directly by following the procedure specified in the Trust's By-laws.

Nominees proposed by shareholders will be considered using the same criteria and in the same manner utilized by the Corporate Governance and Nominating Committee of the Board of Trustees in considering all nominees for election to the Board. See "Committees of the Board of Trustees—Corporate Governance and Nominating Committee."

The Board conducts scheduled executive sessions of the Board of Trustees, attended by only the independent trustees, for each Board meeting. The Lead Independent Trustee presides over these sessions.

All proposals of any shareholder of the Trust that such shareholder wishes to be presented at the 2018 Annual Meeting of Shareholders and included in the proxy statement and form of proxy prepared for that meeting must be received by the Trust at its principal executive offices no later than December 6, 2017 to be considered for inclusion in such proxy statement and form of proxy. Any such proposal must be submitted in writing to the Secretary of the Trust at the address appearing on the

notice accompanying this proxy statement. A proposal which does not comply with the applicable requirements of Rule 14a-8 under the Exchange Act will not be included in management's proxy soliciting material for the 2018 Annual Meeting of Shareholders.

A shareholder of the Trust may wish to have a proposal presented at the 2018 Annual Meeting of Shareholders, but not to have such proposal included in the Trust's proxy statement and form of proxy relating to that meeting. Pursuant to Section 13(a)(2) of the Trust's By-laws, notice of any such proposal must be received by the Trust between February 17, 2018 and March 19, 2018. 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 such proposal must be submitted in writing to the Secretary of the Trust at the address appearing on the notice accompanying this proxy statement.

The cost of the solicitation of proxies will be borne by the Trust. In addition to the use of the mail, solicitations may be made by telephone and personal interviews by officers, trustees and regularly engaged employees of the Trust. The Trust has engaged Innisfree to distribute the Trust's shareholder materials and solicit proxies. The Trust has agreed to pay a fee of approximately $15,000 for such services and to reimburse the solicitor for all reasonable disbursements. Brokerage houses, custodians, nominees and fiduciaries will be requested to forward this proxy statement to the beneficial owners of the shares held of record by such persons, and the Trust will reimburse them for their charges and expenses in this connection.

The Trust will provide without charge to each person solicited by this proxy statement, at the written request of any such person, a copy of the Trust's Annual Report on Form 10-K (including the financial statements and the schedules thereto) as filed with the Securities and Exchange Commission for its most recent fiscal year. Such written requests should be directed to the Vice President of Investor Relations at the address of the Trust appearing on the Notice of Annual Meeting that accompanies this proxy statement.

Certain banks, brokers, broker-dealers and other similar organizations acting as nominee record holders may be participating in the practice of "householding" proxy statements and annual reports. This means that only one copy of this proxy statement and the Trust's 2016 Annual Report on Form 10-K may have been sent to multiple shareholders in your household. If you would prefer to receive separate copies of a proxy statement or annual report for other shareholders in your household, either now or in the future, please contact your bank, broker, broker-dealer or other similar organization serving as your nominee.

Upon written or oral request to Vice President of Investor Relations at the address of the Trust appearing on the Notice of Annual Meeting that accompanies this proxy statement, or via telephone to the Investor Relations department at 610-648-1710, the Trust will promptly provide separate copies of the 2016 Annual Report on Form 10-K and/or this proxy statement. Shareholders sharing an address who are receiving multiple copies of this proxy statement and/or the 2016 Annual Report on Form 10-K and who wish to receive a single copy of these materials in the future will need to contact their bank, broker, broker-dealer or other similar organization serving as their nominee to request that only a single copy of each document be mailed to all shareholders at the shared address in the future.

The undersigned shareholder of LIBERTY PROPERTY TRUST (the "Trust") hereby appoints William P. Hankowsky and Herman C. Fala, and each of them acting individually, as the attorney and proxy of the undersigned, with the powers the undersigned would possess if personally present, and with full power of substitution, to vote all shares of beneficial interest of the Trust which the undersigned would be entitled to vote if personally present at the annual meeting of shareholders of the Trust to be held at 11:00 a.m. local time at The Logan Hotel, One Logan Square, Philadelphia, PA 19103, and any adjournment or postponement thereof, upon all subjects that may properly come before the meeting, including the matters described in the proxy statement furnished herewith, subject to any directions indicated on the reverse side. The Board of Trustees recommends a vote FOR all of the nominees of the Board of Trustees in the election of trustees, FOR approval of the advisory vote to approve the compensation of the Trust's named executive officers, FOR the "1 Year" frequency of voting on the compensation of the Trust's named executive officers and FOR ratification of the selection of Ernst & Young LLP as the Trust's independent registered public accounting firm for 2017.

This proxy when properly executed will be voted in the manner directed herein by the undersigned shareholder(s). If no direction is made, this proxy will be voted "FOR" all of the nominees of the Board of Trustees in the election of trustees, "FOR" approval of the advisory vote to approve the compensation of the Trust's named executive officers, "FOR" the "1 Year" frequency of voting on the compensation of the Trust's named executive officers and "FOR" ratification of the selection of Ernst & Young LLP as the Trust's independent registered public accounting firm for 2017.
