EXPLANATORY NOTE

This report combines the annual reports on Form 10-K for the period ended December 31, 2018 of Liberty Property Trust and Liberty Property Limited Partnership. Unless stated otherwise or the context otherwise requires, references to the “Trust” mean Liberty Property Trust and its consolidated subsidiaries, and references to the “Operating Partnership” mean Liberty Property Limited Partnership and its consolidated subsidiaries. The terms the “Company,” “we,” “our” and “us” mean the Trust and the Operating Partnership, collectively.

The Trust is a self-administered and self-managed Maryland real estate investment trust (“REIT”). Substantially all of the Trust's assets are owned directly or indirectly, and substantially all of the Trust's operations are conducted directly or indirectly, by its subsidiary, the Operating Partnership, a Pennsylvania limited partnership.

The financial results of the Operating Partnership are consolidated into the financial statements of the Trust. The Trust has no significant assets other than its investment in the Operating Partnership. The Trust and the Operating Partnership are managed and operated as one entity. The Trust and the Operating Partnership have the same managers.

The Trust's sole business purpose is to act as the general partner of the Operating Partnership. Net proceeds from equity issuances by the Trust are contributed to the Operating Partnership in exchange for partnership units. The Trust itself does not issue any indebtedness, but guarantees certain of the unsecured debt of the Operating Partnership.

We believe combining the annual reports on Form 10-K of the Trust and the Operating Partnership into this single report results in the following benefits:


•	enhances investors' understanding of the Trust and the Operating Partnership by enabling investors to view the business as a whole in the same manner as management views and operates the business;


•	eliminates duplicative disclosure and provides a more streamlined and readable presentation since a substantial portion of the Company's disclosure applies to both the Trust and the Operating Partnership; and


•	creates time and cost efficiencies through the preparation of one combined report instead of two separate reports.

To help investors understand the significant differences between the Trust and the Operating Partnership, this report presents the following separate sections for each of the Trust and the Operating Partnership:


•	consolidated financial statements;


•	the following notes to the consolidated financial statements;


◦	Income per Common Share of the Trust and Income per Common Unit of the Operating Partnership;


◦	Noncontrolling Interests of the Trust and Limited Partners' Equity and Noncontrolling Interest of the Operating Partnership

This report also includes separate Item 9A. Controls and Procedures sections and separate Exhibit 31 and 32 certifications for each of the Trust and the Operating Partnership in order to establish that the Chief Executive Officer and the Chief Financial Officer of each entity have made the requisite certifications and that the Trust and Operating Partnership are compliant with Rule 13a-15 and Rule 15d-15 of the Securities Exchange Act of 1934, as amended.

PART I

ITEM 1. BUSINESS

The Company

Liberty Property Trust (the "Trust") is a self-administered and self-managed Maryland real estate investment trust (a "REIT"). Substantially all of the Trust's assets are owned directly or indirectly, and substantially all of the Trust's operations are conducted directly or indirectly, by its subsidiary, Liberty Property Limited Partnership, a Pennsylvania limited partnership (the "Operating Partnership" and, together with the Trust and their consolidated subsidiaries, the "Company").

The Company completed its initial public offering in 1994 to continue and expand the commercial real estate business of Rouse & Associates, a Pennsylvania general partnership, and certain affiliated entities (collectively, the "Predecessor"), which was founded in 1972.

As of December 31, 2018 the Company owned the following "Properties in Operation" (square feet in thousands):



	Number of Operating Industrial Properties	Number of Operating Office Properties	Total Number of Properties	Total Square Feet
"Wholly Owned Properties in Operation"	480	22	502	91,248
"JV Properties in Operation" (at 100%)	48	18	66	14,853
"Properties in Operation"	528	40	568	106,101

As of December 31, 2018 the Company owned the following "Properties under Development" and "Properties held for Redevelopment/Value-Added" (square feet upon completion in thousands):



	Number of Properties	Total Square Feet
"Wholly Owned Properties under Development"	29	8,195
"JV Properties under Development" (at 100%)	2	134	⁽¹⁾
"Properties under Development"	31	8,329

"Wholly Owned Properties held for Redevelopment/Value-Added"	7	868
"JV Properties held for Redevelopment/Value-Added" (at 100%)	1	48
"Properties held for Redevelopment/Value-Added"	8	916

(1) Including a 217-room hotel, which is excluded from square footage total.

The Company also owned 1,283 acres of developable land and through unconsolidated joint ventures 339 acres of developable land substantially all of which is zoned for commercial use.

The Properties in Operation, collectively with the Properties under Development and Properties held for Redevelopment/Value-Added are referred to as, the "Properties".

As previously reported, and as further summarized below in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations”, the Company undertook several significant transactions in recent years consistent with its strategy to divest its remaining office Properties (other than its headquarters) and focus its efforts and capital solely on its industrial platform, which favors industrial properties and markets with strong demographic and economic fundamentals. In furtherance of this strategy, the Company has substantially divested of its suburban office Properties, and expects to divest its remaining metro-office Properties over the next few years. The Company plans to reinvest the proceeds of these divestments in acquisitions in targeted industrial markets and new development.

The Company provides leasing, property management, development and other tenant-related services for the Properties. The industrial Properties consist of a variety of warehouse, distribution, service, assembly, light manufacturing and research and development facilities. They include both single-tenant and multi-tenant facilities, with most designed flexibly to accommodate various types of tenants, space requirements and industrial uses.

Table of Contents

The Trust is the sole general partner and also a limited partner of the Operating Partnership, owning 97.7% of the common equity of the Operating Partnership at December 31, 2018. The common units of limited partnership interest in the Operating Partnership (the "Common Units"), other than those owned by the Trust, are exchangeable on a one-for-one basis (subject to anti-dilution protections) for the Trust's common shares of beneficial interest, $0.001 par value per share (the "Common Shares"). As of December 31, 2018, the Common Units held by the limited partners were exchangeable for 3.5 million Common Shares. The ownership of the holders of Common Units is reflected on the Trust's financial statements as “noncontrolling interest- operating partnership” as a component of total equity. The ownership of the holders of Common Units not owned by the Trust is reflected on the Operating Partnership's financial statements as “limited partners' equity” as a component of total owners' equity.

Management and Employees

As of February 8, 2019, the Company had 271 employees. The Company maintains an in-house leasing and property management staff which the Company believes enables it to better understand the characteristics of the local markets in which it operates, to respond quickly and directly to tenant needs and to better identify local real estate opportunities. In certain circumstances the Company also engages and directs the activities of third party property managers and leasing agents.

Business Objective and Strategies for Growth

The Company's business objective is to maximize long-term profitability for its shareholders by operating as a leader in commercial real estate through the ownership, management, development and acquisition of superior industrial properties. The Company intends to achieve this objective by owning and operating industrial properties in the United States nationally, as well as in the United Kingdom. Additionally, to achieve this objective, the Company intends to divest its remaining office properties (other than its headquarters). The Company believes that pursuing this objective will provide the benefits of enhanced investment opportunities, economies of scale, risk diversification, access to capital and the ability to attract and retain personnel. The Company also strives to provide an exceptional and positive tenant experience. The Company is committed to developing and owning high-performing sustainable buildings and operating an energy-efficient portfolio. In pursuing its business objective, the Company seeks to achieve a combination of internal and external growth, maintain a conservative balance sheet and pursue a strategy of financial flexibility.

Products

Table of Contents

The Company strives to be a high quality provider of industrial properties and favors markets with strong demographic and economic fundamentals. In addition, the Company has also developed properties on a fee basis for unrelated third parties or unconsolidated joint ventures in which the Company has an interest. However, the Company believes that any new such projects will be focused on industrial and will be more limited in scope and scale going forward.

Markets

The Company owns and operates industrial properties in the United States nationally, as well as in the United Kingdom. Generally, the Company seeks to have a presence in each market sufficient for the Company to compete effectively in that market. The Company gathers information from internal sources and independent third parties and analyzes this information to support its evaluation of current and new markets and market conditions.

Organizational Plan

The Company seeks to maintain a management organization that facilitates efficient execution of the Company's strategy. As part of this effort, the Company pursues a human resources plan designed to create and maintain a highly effective real estate company through recruiting, training and retaining capable people. The structure is designed to support a local and regional platform operating within a value-added corporate structure. The Company seeks to provide management and all employees with technology tools to enhance competitive advantage and more effectively execute on strategic and operational goals.

Internal Growth Strategies

The Company seeks to maximize the profitability of its Properties by endeavoring to maintain high occupancy levels while obtaining competitive rental rates, controlling costs and focusing on customer service efforts.

Maintain High Occupancies

The Company believes that the quality and diversity of its tenant base and its strategy of operating in multiple markets is integral to achieving its goal of attaining high occupancy levels for its portfolio. The Company targets financially stable tenants in an effort to minimize uncertainty relating to the ability of the tenants to meet their lease obligations.

Cost Controls

The Company seeks to identify best practices to apply throughout the Company in order to enhance cost savings and other efficiencies. The Company also employs an annual capital improvement and preventative maintenance program designed to reduce operating costs and maintain the long-term value of the Properties in Operation.

Customer Service

The Company seeks to achieve high tenant retention through a comprehensive customer service program, which is designed to provide an exceptional and positive tenant experience. The customer service program establishes best practices and provides an appropriate customer feedback process. The Company believes that the program has been helpful in increasing tenant satisfaction.

High Performance Buildings

The Company is committed to the sustainable design, development and operation of its portfolio. The Company strives to create work environments that limit resource consumption, improve building performance and promote human health and productivity. The Company believes that sustainable, high performance buildings and environmentally responsible business practices are not only good for the environment, but that they also create value for the Company's tenants and shareholders.

The Company's efforts have included research, development, and deployment of sustainable building strategies and technologies, tenant outreach and education, and LEED accreditation for its development, property management and leasing staff.

The Company has utilized the U.S. Green Building Council's LEED rating system and the U.S. Department of Energy's ENERGY STAR system to drive energy efficiency and sustainable construction across its buildings and operations. As of December 31, 2018, either directly or through equity interests in unconsolidated joint ventures, the Company owns or has under construction 97 LEED buildings and has one building in the United Kingdom constructed under the international BREEAM standards. The Company has 9 ENERGY STAR-certified buildings and pursues energy and water efficient performance in the Properties in Operation. It is the Company's intention to obtain LEED or UK equivalent accreditation for all of its development properties.

Table of Contents

External Growth Strategies

The Company seeks to enhance its long-term profitability through the development, acquisition and disposition of properties either directly or through joint ventures. The Company also considers acquisitions of real estate operating companies.

Wholly Owned Properties

Development

The Company's development investment strategy focuses primarily on the development of high-quality industrial properties within its existing markets. When the Company's marketing efforts identify opportunities, the Company will consider pursuing such opportunities outside of the Company's established markets. The Company and its Predecessor have developed over 90 million square feet of commercial real estate during the past 46 years. The Company's development activities generally fall into two categories: build-to-suit projects and projects built for inventory (projects that are less than 75% pre-leased prior to commencement of construction). The Company develops build-to-suit projects for existing and new tenants. The Company also builds projects for inventory where the Company has identified sufficient demand at market rental rates to justify such construction.

During the year ended December 31, 2018, the Company brought into service 16 wholly owned inventory projects totaling 4.7 million square feet and representing an aggregate Total Investment of $434.7 million. As of December 31, 2018, these completed development properties were 81.1% leased.

As of December 31, 2018, the Company had 29 Wholly Owned Properties under Development, which are expected to comprise, upon completion, 8.2 million square feet and are expected to represent a Total Investment of $735.0 million. These Wholly Owned Properties under Development were 36.3% pre-leased as of December 31, 2018. The scheduled deliveries of the 8.2 million square feet of Wholly Owned Properties under Development are as follows (in thousands, except percentages):



		PERCENT PRE-LEASED		TOTAL
SCHEDULED IN-SERVICE DATE	SQUARE FEET	DECEMBER 31, 2018		INVESTMENT
1st Quarter, 2019	674	84.6	%	$	66,236
2nd Quarter, 2019	1,600	78.5	%	139,106
3rd Quarter, 2019	1,938	33.9	%	130,175
4th Quarter, 2019	466	7.4	%	53,697
1st Quarter, 2020	831	43.5	%	77,174
2nd Quarter, 2020	1,083	8.8	%	99,601
3rd Quarter, 2020	455	—	%	45,263
4th Quarter, 2020	1,148	—	%	123,708
TOTAL	8,195	36.3	%	$	734,960

“Total Investment” for a Property Under Development is defined as the sum of the land costs and the costs of land improvements, building and building improvements, lease transaction costs, and where appropriate, other development costs and carrying costs.

The Company believes that, because it is a fully integrated real estate firm, its base of commercially zoned land provides a competitive advantage for future development activities. As of December 31, 2018, the Company owned 1,283 acres of land held for development, substantially all of which is zoned for commercial use. Substantially all of the land is located adjacent to or within existing industrial or business parks with site improvements, such as public sewers, water and utilities, available for service. The Company estimates that its land holdings would support, as and when developed, approximately 15.2 million square feet. The Company's investment in land held for development as of December 31, 2018 was $296.2 million.

Through a development agreement with Kent County Council, the Company develops commercial buildings at Kings Hill, a 650-acre mixed use development site in the County of Kent, England. The Company is also the development and project manager for the installation of infrastructure on the site and receives a portion of the proceeds from the sale of serviced residential land development parcels to house builders. The Kings Hill project originally had planning consent and available land for approximately 1.35 million square feet gross of commercial space of which approximately 1.0 million square feet gross has been built as of December 31, 2018. During 2015, the Company obtained outline planning consent to re-zone some of the remaining commercial development land for a further 635 homes at Kings Hill, taking the total consent to 3,486 homes of which 2,884 had been sold as of December 31, 2018. In 2018, the Company submitted new outline planning applications for further residential development on the project, some of which covers the remaining land originally zoned for commercial development.

Table of Contents

Acquisitions/Dispositions

The Company seeks to acquire properties consistent with its business objectives and strategy. The Company executes its acquisition strategy by purchasing properties that the Company believes will create shareholder value over the long-term.

During the year ended December 31, 2018, the Company acquired 16 operating properties for a purchase price of $494.3 million. These properties contain 4.1 million square feet and were 61.0% leased as of December 31, 2018. The Company also acquired 12 parcels of land totaling 274.9 acres for an aggregate purchase price of $138.3 million.

The Company disposes of properties and land held for development that no longer fit within the Company's strategic plan, or with respect to which the Company believes it can optimize cash proceeds. The Company may also, from time to time, sell properties to its tenants pursuant to purchase options contained in their leases. During the year ended December 31, 2018, the Company sold 39 Wholly Owned Properties containing an aggregate of 3.4 million square feet, development rights in the UK and 79.1 acres of land for aggregate proceeds of $873.4 million.

Joint Venture Properties

The Company, from time to time, considers joint venture opportunities with institutional investors or other real estate companies. Joint venture partnerships provide the Company with additional sources of capital to share investment risk and fund capital requirements. In some instances, joint venture partnerships provide the Company with additional local market or product type expertise.

As of December 31, 2018, the Company had investments in and advances to unconsolidated joint ventures totaling $351.0 million (see Note 7 to the Company's Consolidated Financial Statements).

Development

During the year ended December 31, 2018, an unconsolidated joint venture in which the Company held an interest brought into service a build to suit totaling 302,000 square feet and representing a Total Investment of $21.0 million. As of December 31, 2018, the completed development property was 100.0% leased. As of December 31, 2018, the Company had one JV Property under Development, which is expected to comprise, upon completion, 134,000 square feet and is expected to represent a Total Investment of $10.3 million. This JV Property under Development was 54.6% pre-leased as of December 31, 2018.

During the year ended December 31, 2018, the joint venture owning the office portion of the Comcast Technology Center brought into service 250,000 square feet of office space representing a Total Investment by such joint venture of $136.1 million. During the year ended December 31, 2017, the joint venture owning the office portion of the Comcast Technology Center brought into service 1.1 million square feet of office space representing a Total Investment by such joint venture of $599.6 million. The office portion of the Project is now substantially complete. The 217-room Four Seasons hotel representing an aggregate Total Investment by the joint venture owning the hotel portion of the Comcast Technology Center of $225.5 million when completed continued to be developed by such joint venture as of December 31, 2018.

As of December 31, 2018, unconsolidated joint ventures in which the Company held an interest owned 339 acres of land held for development. Substantially all of the land held for development is zoned for commercial use and is located adjacent to or within existing industrial or business parks with site improvements, such as public sewers, water and utilities, available for service. The Company estimates that its joint venture land holdings would support, as and when developed, approximately 6.2 million square feet.

Acquisitions/Dispositions

During the year ended December 31, 2018, none of the unconsolidated joint ventures in which the Company holds an interest acquired or sold any operating properties or land parcels.

ITEM 1A. RISK FACTORS

The Company's results of operations and the ability to make distributions to our shareholders and service our indebtedness may be affected by the risk factors set forth below. (The Company refers to itself as "we," "us" or "our" in the following risk factors.) This section contains some forward looking statements. You should refer to the explanation of the qualifications and limitations on forward-looking statements in Item 7 - Management's Discussion and Analysis of Financial Condition and Results of Operations.

Risks Related to Our Business

The Company's business is subject to the risks in this section.

We may face risks associated with our current business strategy.

As previously reported, and as further summarized below in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” we undertook several significant transactions in recent years, consistent with our strategy to divest our office Properties (other than our headquarters) and focus our efforts and capital solely on our industrial platform, which favors industrial properties and markets with strong demographic and economic fundamentals. In furtherance of this strategy, we have substantially divested of our suburban office Properties, and expect to divest our remaining metro-office Properties over the next few years. We plan to reinvest the proceeds of these divestments in acquisitions in targeted industrial markets and new development.

While management believes that this strategy will be in the best long-term interests of the Company and its shareholders, in the near term, this strategy will be dilutive to operating cash flow and we cannot assure you that this strategy will produce the intended benefit, or when, if ever, those intended benefits will be achieved. This strategy poses certain risks, including without limitation the following:


▪	for similar investment dollars, rental income from industrial properties is generally less in the short term than rental income generated from office properties


▪	our expectation of increasing demand and increasing stability of value in the industrial sector may not materialize


▪	the relative advantages in the ownership of industrial properties as opposed to office properties will be affected by variable and unpredictable macro-economic and global conditions that are outside of our control


▪	our identification of markets with strong demographic and economic fundamentals may prove erroneous, due to macro-economic and global conditions that are outside of our control


▪	our expectation of proceeds from the divestiture of our office properties may be impacted by erosion in demand for such asset class

Failure of our strategy to achieve the intended benefits could have a material adverse effect on our results of operations, financial condition and liquidity.

Unfavorable events affecting our existing tenants and potential tenants, or negative market conditions that may affect our existing tenants and potential tenants, could have an adverse impact on our ability to attract new tenants, relet space, collect rent or renew leases, and thus could have a negative effect on our cash flow from operations.

Our cash flow from operations depends on our ability to lease space to tenants on economically favorable terms. Therefore, we could be adversely affected by various factors and events over which we have limited control, such as:


▪	lack of demand for space in the areas where our Properties are located


▪	inability to retain existing tenants and attract new tenants


▪	oversupply of space and changes in market rental rates


▪	defaults by our tenants or their failure to pay rent on a timely basis


▪	the need to periodically renovate and repair our space


▪	physical damage to our Properties


▪	economic or physical decline of the areas where our Properties are located


▪	potential risk of functional obsolescence of our Properties over time

If a tenant is unable to pay rent due to us, we may be forced to evict the tenant, or engage in other remedies, which may be expensive and time consuming and may adversely affect our net income, shareholders' equity and cash distributions to shareholders. In addition, a tenant may become the subject of bankruptcy or reorganization protection, which would allow it to reject its leases with us and thereby terminate its obligation to pay rent.

If our tenants do not renew their leases as they expire, we may not be able to rent the space. Furthermore, leases that are renewed, and some new leases for space that is relet, may have terms that are less economically favorable to us than current lease terms, or may require us to incur significant costs, such as for renovations, tenant improvements or lease transaction costs.

Any of these events could adversely affect our cash flow from operations and our ability to make expected distributions to our shareholders and service our indebtedness.

Table of Contents

A significant portion of our costs, such as real estate taxes, insurance costs, and debt service payments, generally are not reduced when circumstances cause a decrease in cash flow from our Properties.

We may not be able to compete successfully with other entities that operate in our industry.

We experience a great deal of competition in attracting tenants for our Properties and in locating land to develop and properties to acquire.

In our effort to lease our Properties, we compete for tenants with a broad spectrum of other landlords in each of our markets. These competitors include, among others, publicly-held REITs, privately-held entities, individual property owners and tenants who wish to sublease their space. Some of these competitors may be able to offer prospective tenants more attractive financial or other terms than we are able to offer.

We may experience increased operating costs, which could adversely affect our operations.

Our Properties are subject to increases in operating expenses such as real estate taxes, insurance, cleaning, electricity, heating, ventilation and air conditioning, general and administrative costs and other costs associated with security, landscaping, repairs and maintenance. While our current tenants generally are obligated to pay a significant portion of these costs, there is no assurance that these tenants will make such payments or agree to pay these costs upon renewal or that new tenants will agree to pay these costs. If operating expenses increase in our markets, we may not be able to increase rents or reimbursements in all of these markets so as to meet increased expenses without simultaneously decreasing occupancy rates. If this occurs, our ability to make distributions to shareholders and service our indebtedness could be adversely affected.

Our ability to achieve growth in operating income depends in part on our ability to develop properties, which may suffer under certain circumstances.

We intend to continue to develop properties when warranted by market conditions. Our general construction and development activities include the risks that:


▪	construction and leasing of a property may not be completed on schedule, which could result in increased expenses and construction costs, and would result in reduced profitability


▪	construction costs may exceed our original estimates due to increases in interest rates and increased materials, labor or other costs, possibly making the property unprofitable or less profitable than projected because we may not be able to increase rents to compensate for the increase in construction costs


▪	we may be unable to obtain, or may face delays in obtaining, required zoning, land-use, building, occupancy, and other governmental permits and authorizations, which could result in increased costs and could require us to abandon our activities entirely with respect to a project


▪	we may abandon development opportunities after we begin to explore them and as a result, we may fail to recover costs already incurred. If we alter or discontinue our development efforts, costs of the investment may need to be expensed rather than capitalized and we may determine the investment is impaired, resulting in a loss


▪	we may expend funds on and devote management's time to projects that we do not complete


▪	occupancy rates and rents at newly completed properties may not meet our expectations. This may result in lower than projected occupancy and rental rates with the result that our investment is not profitable or less profitable than projected


▪	we may incur losses under construction warranties, guaranties and delay damages under our contracts with tenants and other customers

We face risks when we develop properties on a fee basis for joint ventures in which we hold an interest or for unrelated third parties.

From time to time the Company has agreed to develop properties on a fee basis for joint ventures in which we hold an interest or for unrelated third parties, in addition to developing properties to be wholly owned in our own portfolio. In these cases we have typically agreed to be responsible for all aspects of the development of the project and to guarantee the timely lien-free completion of construction of the project and the payment, subject to certain exceptions, of cost overruns incurred in the development of the project. For example, in addition to the Comcast Technology Center project discussed below, in 2016 we entered into an agreement to develop a corporate headquarters office building for American Water Works, Inc. in Camden, New Jersey for an estimated total building cost as of December 31, 2018 of $147.8 million, plus overall project infrastructure in the amount of $23.1 million. If we had encountered construction delays or unexpected costs in the development of this project or other similar projects, the resulting additional costs incurred and potential payments to the customer would adversely affect our cash flow and net income, and as such have a material adverse effect on our results of operations, financial condition and liquidity.

Table of Contents

Our development of Comcast Technology Center exposes us to certain risks.

In 2014, the Company entered into two joint ventures with Comcast Corporation for the purpose of developing and owning the Comcast Technology Center located in Philadelphia, Pennsylvania as part of a mixed-use development. The 60-story building includes 1.3 million square feet of leasable office space, which is substantially complete, and will include a 217-room Four Seasons Hotel. Projected costs for this development, exclusive of tenant-funded interior improvements, are anticipated to be approximately $961.2 million. The Company's investment in the project is expected to be approximately $192.2 million with 20% ownership interests in both joint ventures. The two joint ventures have engaged the Company as the developer of the project pursuant to a Development Agreement by which the Company agrees, in consideration for a development fee, to be responsible for all aspects of the development of the project and to guarantee the timely lien-free completion of construction of the project and the payment, subject to certain exceptions, of any cost overruns incurred in the development of the project. To mitigate this risk, the Company entered into guaranteed maximum price contracts with a third party contractor to construct the project. Comcast Corporation has entered into a lease for 100% of the office space in the building.

Development of a project such as the Comcast Technology Center is subject to the general development and construction risks noted above. Those risks are magnified by the size of the project, and include construction risks and cost overrun risks associated with a construction project with the engineering and design complexities of a high rise mixed-use building. If we fail to complete the development of the project in compliance with the deadlines set forth in the lease with Comcast Corporation, or if the costs of development exceed the budgets agreed upon by the joint ventures, the Company could be liable for substantial damages and costs. We have been notified by the contractor under our guaranteed maximum price contracts that the contractor has incurred cost overruns and expects to incur additional construction costs in connection with completing the project in excess of the guaranteed maximum price payable to the contractor under the guaranteed maximum price contracts, which guaranteed maximum price previously has been adjusted pursuant to accepted change orders. The general contractor has generally refused to fund these additional costs, and we have begun to fund and may continue to fund cost overruns in compliance with our obligations under the development cost guarantee to the joint ventures. We have accrued such amounts as additional development service fee expense in our consolidated statements of comprehensive income for the year ended December 31, 2018. As of such date, we had accrued $67.1 million relating to the above-described development cost guarantees which are included in other liabilities in the accompanying consolidated balance sheets.

In addition to the costs to comply with the Company's obligations under its development cost guarantee, claims have been asserted by the third-party contractor and certain subcontractors. There can be no assurances that amounts incurred, including as a result of such claims, will not exceed the above estimates. We are not able to reasonably estimate the amount of additional expenses, if any, that we may incur as a result of such claims, and accordingly any potential exposure of the Company for such claims is not included within the accrual described above. If we were to incur additional expenses in connection with our development cost guarantee or in connection with such claims, such amounts would be accrued when they are determined to be probable of being incurred and are reasonably estimable, and could be material to the Company’s results of operations in future periods. If we were to subsequently recover any of the cost overruns initially funded by the Company, such recoveries would be recorded when and if realized in future periods.

The ownership of a hotel, with which our employees have limited experience, exposes us to additional risks beyond the customary risks of owning industrial and office rental properties as described above. These additional risks include the risk of highly volatile market cycles for the hotel industry in general and luxury hotels in particular, risks that room rates may not be able to keep up with increasing operating costs, risks of increased competition from the development of new hotels, and increased risk of employment liability and other potential exposures in connection with owning an operating business as opposed to owning and managing rental real estate.

We face risks associated with property acquisitions.

We acquire individual properties and portfolios of properties, in some cases through the acquisition of operating entities, and intend to continue to do so when circumstances warrant.

Our acquisition activities and their success are generally subject to the following risks:


▪	when we are able to locate a desirable property, competition from other real estate investors may significantly increase the purchase price


▪	acquired properties may fail to perform as expected


▪	the actual costs of repositioning or redeveloping acquired properties may be higher than our estimates


▪	acquired properties may be located in new markets where we face risks associated with an incomplete knowledge or understanding of the local market, a limited number of established business relationships in the area and a relative unfamiliarity with local governmental and permitting procedures

Table of Contents


▪	we may be unable to quickly and efficiently integrate new acquisitions, particularly acquisitions of portfolios of properties and operating entities, into our existing operations, and as a result, our results of operations and financial condition could be adversely affected

We may acquire properties subject to liabilities and without any recourse, or with only limited recourse, with respect to unknown liabilities. As a result, if a liability were asserted against us based upon ownership of those properties, we might have to pay substantial sums to settle it, which could adversely affect our cash flow.

Many of our Properties are concentrated in our primary markets, and we therefore may suffer economic harm as a result of adverse conditions in those markets.

Our Properties are located principally in specific geographic areas. Due to the concentration of our Properties in these areas, performance is dependent on economic conditions in these areas.

The value and the marketability of some of our Properties may be reduced as the result of the expiration or loss of local tax abatements, tax credit programs, or other governmental incentives.

Certain of our Properties have the benefit of governmental tax incentives aimed at inducing office or industrial users to relocate to areas and neighborhoods which have not historically seen robust commercial development. These incentives typically have specific sunset provisions and may be subject to governmental discretion in the eligibility or award of the applicable incentives. For example, the Pennsylvania Keystone Opportunity Zones applicable to our Properties in the Philadelphia Navy Yard Corporate Center expired on December 31, 2018 or will expire on December 31, 2025 (as applicable) and the Grow NJ tax credit program applicable to our properties in the Camden Waterfront project expires on June 30, 2019 and is subject to the approval of each project by certain agencies and officers of the State of New Jersey. The expiration of these incentive programs or the inability of potential tenants or users to be eligible for or to obtain governmental approval of the incentives may have an adverse effect on the value of our Properties and thus have an adverse impact on our efforts to divest these Properties on attractive terms or at all, and may also have an adverse effect on our cash flow and net income, and result in impairment charges.

Our Properties may be subject to impairment charges.

We continually evaluate the recoverability of the carrying value of our Properties, whether Development Properties (including land held for development), Properties Held for Redevelopment or Properties in Operation, as well as land and infrastructure being developed on a fee basis, under generally accepted accounting principles. Factors considered in evaluating impairment of our Properties include significant declines in operating revenues, recurring operating losses and other significant adverse changes in general market conditions, and, in the case of Development Properties (including land held for development as well as land and infrastructure being developed on a fee basis), the abandonment of a project or the determination by management that future development is unlikely to occur or is unlikely to produce adequate cash flows to recover the carrying value of the Property. Generally, a Property held for investment is not considered impaired if the undiscounted estimated future cash flows of the Property over its estimated holding period are in excess of the Property’s net book value at the balance sheet date. If held for sale, a Property is not considered impaired unless its estimated fair value (less costs to sell) is less than the Property's book value at the balance sheet date. Assumptions used to estimate market values, annual and residual cash flows and estimated holding period of such assets require the judgment of management.

The Company has recorded impairment charges in the current and prior years and there can be no assurance that we will not take additional charges in the future related to the impairment of our Properties. We believe we have applied reasonable estimates and judgments in determining the proper classification of our Properties. However, these estimates require the use of estimated market values, which are difficult to assess. Should external or internal circumstances change, requiring the need to shorten holding periods or adjust the estimated future cash flows of certain Properties, we could be required to record additional impairment charges. Any future impairment could have a material adverse effect on our results of operations and funds from operations.

Property ownership through joint ventures will limit our ability to act exclusively in our interests and may require us to depend on the financial performance of our co-venturers.

From time to time we invest in joint ventures in which we do not hold a controlling interest. These investments involve risks that do not exist with properties in which we own a controlling interest, including the possibility that our partners may, at any time, have business, economic or other objectives that are inconsistent with our objectives. In instances where we lack a controlling interest, our partners may be in a position to require action that is contrary to our objectives. While we seek to negotiate the terms of these joint ventures in a way that secures our ability to act in our best interests, there can be no assurance that those terms will

Table of Contents

be sufficient to fully protect us against actions contrary to our interests. If the objectives of our partners are inconsistent with ours, we may not in every case be able to act exclusively in our interests.

Additionally, our joint venture partners may experience financial difficulties or change their investment philosophies. This may impair their ability to meet their obligations to the joint venture, such as with respect to providing additional capital, if required. If such a circumstance presented itself we may be required to perform on their behalf, if possible, or suffer a loss of all or a portion of our investment in the joint venture.

We could suffer adverse effects if we were to experience security breaches through cyber attacks.

We are subject to risks from security breaches and other significant disruptions of our information technology networks and related systems, which are essential to our business operations. Such breaches and disruptions may occur through cyber attacks or cyber intrusions over the Internet, persons inside our organization or persons with access to systems inside our organization. Certain of our tenants are in the financial and retail industries, which have been particular targets of cyber attacks, and as a result, we may be especially likely to be targeted by cyber attacks. We cannot provide assurance that our activities to maintain the security and integrity of our networks and related systems will be effective. A security breach involving our networks and related systems could disrupt our operations in numerous ways, including by creating difficulties for our tenants which could result in financial or reputational harm to us.

We may not be able to access financial markets to obtain capital on a timely basis, or on acceptable terms.

Our ability to access the public debt and equity markets depends on a variety of factors, including:


▪	general economic conditions affecting these markets


▪	our own financial structure and performance


▪	the market's opinion of REITs in general


▪	the market's opinion of REITs that own properties similar to ours

We may suffer adverse effects as a result of the terms of and covenants relating to our indebtedness.

Required payments on our indebtedness generally are not reduced if the economic performance of our portfolio of Properties declines. If the economic performance of our Properties declines, net income, cash flow from operations and cash available for distribution to shareholders will be reduced. If payments on debt cannot be made, we could sustain a loss, or in the case of mortgages, suffer foreclosures by mortgagees or suffer judgments. Further, some obligations, including our $930 million of aggregate credit facilities and $2.3 billion in unsecured notes issued in past public offerings, contain cross-default and/or cross-acceleration provisions, which means that a default on one obligation may constitute a default on other obligations.

Our credit facilities and unsecured debt securities contain customary restrictions, requirements and limitations on our ability to incur indebtedness, including total debt to total asset ratios, secured debt to total asset ratios, debt service coverage ratios and minimum ratios of unencumbered assets to unsecured debt which we must maintain. Our continued ability to borrow under our $930 million of aggregate credit facilities is subject to compliance with our financial and other covenants. In addition, our failure to comply with such covenants could cause a default under these credit facilities, and we may then be required to repay such debt with capital from other sources. Under those circumstances, other sources of capital may not be available to us, or be available only on unattractive terms.

Our degree of leverage could limit our ability to obtain additional financing.

Our degree of leverage could affect our ability to obtain additional financing for working capital, capital expenditures, acquisitions, development or other general corporate purposes. Our senior unsecured debt is currently rated investment grade by the three major rating agencies. However, there can be no assurance we will be able to maintain this rating, and in the event our senior debt is downgraded from its current rating, we would likely incur higher borrowing costs. Our degree of leverage could also make us more vulnerable to a downturn in business or the economy generally.

Further issuances of equity securities may be dilutive to our existing shareholders.

The interests of our existing shareholders could be diluted if we issue additional equity securities to finance future developments, acquisitions, or repay indebtedness. Our Board of Trustees can authorize the issuance of additional securities without shareholder approval. Our ability to execute our business strategy depends on our access to an appropriate blend of debt financing, including unsecured lines of credit and other forms of secured and unsecured debt, and equity financing, including issuances of common and preferred equity.

Table of Contents

An increase in interest rates would increase our interest costs on variable rate debt and could adversely impact our ability to refinance existing debt or dispose of properties in accordance with our strategy.

We currently have, and may incur more, indebtedness that bears interest at variable rates. Accordingly, if interest rates increase, so will our interest costs, which would adversely affect our cash flow and our ability to pay principal and interest on our debt and our ability to make distributions to our shareholders. Further, rising interest rates could limit our ability to refinance existing debt when it matures.

From time to time, we enter into interest rate swap agreements and other interest rate hedging contracts, including swaps, caps and floors. While these agreements are intended to lessen the impact of rising interest rates on us, they also expose us to the risks that the other parties to the agreements might not perform, or that we could incur significant costs associated with the settlement of the agreements, or that the agreements might be unenforceable and the underlying transactions would fail to qualify as highly-effective cash flow hedges under guidance included in ASC 815 “Derivatives and Hedging.”

In addition, an increase in interest rates could decrease the amounts third parties are willing to pay for our assets, thereby limiting our ability to change our portfolio promptly in response to changes in economic or other conditions.

The replacement of LIBOR with an alternative reference rate may adversely affect interest expense related to outstanding debt.

On July 27, 2017, the Financial Conduct Authority, or FCA, announced that it would phase out LIBOR as a benchmark by the end of 2021. It is unclear whether new methods of calculating LIBOR will be established such that it continues to exist after 2021. When LIBOR ceases to exist, we may need to amend the credit and loan agreements with our lenders that utilize LIBOR as a factor in determining the interest rate based on a new standard that is established, if any. The transition to an alternative rate will require careful and deliberate consideration and implementation so as to not disrupt the stability of financial markets. There is no guarantee that a transition from LIBOR to an alternative will not result in financial market disruptions, significant increases in benchmark rates, or borrowing costs to borrowers, any of which could have an adverse effect on our business, results of operations and financial condition.

Significant developments stemming from the U.K.’s referendum on membership in the EU could have a material adverse effect on us.

We own properties and land in the United Kingdom. On June 23, 2016, the U.K. held a referendum and voted in favor of leaving the European Union, or EU (commonly referred to as “Brexit”). The U.K.’s exit from the EU is expected to occur by the end of March 2019, but the U.K. government has thus far not passed a withdrawal agreement through Parliament, and has experienced difficulty in its efforts to do so. If an agreement can be passed by March 29, 2019, there will be a transition period through December 2020 to allow for businesses and individuals to adjust to its changes. Otherwise, the U.K. is expected to be required to leave the EU without an agreement or transition period in place. Brexit has created political and economic uncertainty, particularly in the U.K. and the EU. Our business could be affected during this period of uncertainty, and perhaps longer, by the impact of the U.K. referendum. In addition, our business could be negatively affected by new trade agreements between the U.K. and other countries, including the U.S., and by the possible imposition of trade or other regulatory barriers in the U.K. These possible negative impacts, and others resulting from the U.K.’s actual or threatened withdrawal from the EU, may adversely affect our business, results of operations and financial condition.

A depreciation in the value of the foreign currency in the U.K. could have a material adverse effect on us.

We own properties and land in the United Kingdom. As a result, we are subject to foreign currency risk due to potential fluctuations in exchange rates between the British pound sterling and the U.S. dollar. A significant change in the value of the British pound sterling may have a material adverse effect on our business and, specifically, our U.S. dollar reported financial position and results of operations.

Any major disruption or failure of our information technology systems, or our failure to successfully implement new technology effectively, could adversely affect our business and operations.

We rely on various information technology systems, owned by us and third parties, to manage our operations. Over the last several years, we have been and continue to implement modifications and upgrades to our systems, including making changes to legacy systems, replacing legacy systems with successor systems with new functionality and acquiring new systems with new functionality. We recently implemented a significant change to our HR software platform, essentially now utilizing a single software platform to take the place of numerous previous applications, and during 2019, we expect to replace the basic business software application that governs most aspects of our operations. These activities subject us to inherent costs and risks associated with replacing and

Table of Contents

upgrading these systems, including diminished ability to respond to tenant needs, potential disruption of our internal control structure, substantial capital expenditures, additional administration and operating expenses, retention of sufficiently skilled personnel to implement and operate the new systems, demands on management time, and other risks and costs of delays or difficulties in transitioning to new or upgraded systems or of integrating new or upgraded systems into our current systems. Our system implementations may not result in productivity improvements at a level that outweighs the costs of implementation, or at all. In addition, the difficulties with implementing new or upgraded technology systems may cause disruptions in our business operations and have an adverse effect on our business, results of operations and financial condition.

Changes in accounting pronouncements may materially and adversely affect our financial statements, our tenants’ credit quality and our ability to secure long-term leases and renewal options.

Accounting policies and methods are fundamental to how we record and report our financial condition and results of operations. Uncertainties posed by various initiatives of accounting standard-setting by the Financial Accounting Standards Board and the Securities and Exchange Commission, which create and interpret applicable accounting standards for U.S. companies, may change the financial accounting and reporting standards or their interpretation and application of these standards that govern the preparation of our financial statements. These changes could have a material impact on our reported financial condition and results of operations. In some cases, we could be required to apply a new or revised standard retroactively, resulting in potentially material restatements of prior period financial statements. Similarly, these changes could have a material impact on our tenants’ reported financial condition or results of operations or could affect our tenants’ preferences regarding leasing real estate.

The Financial Accounting Standards Board issued an accounting standard, effective for us for reporting periods beginning after December 15, 2018, that requires companies to capitalize all leases on their balance sheets by recognizing a lessee's rights and obligations. Many companies that account for certain leases on an "off balance sheet" basis will be required to account for such leases "on balance sheet." This change will remove many of the differences in the way companies account for owned property and leased property, and could have a material effect on various aspects of our tenants' businesses, including their credit quality and the factors they consider in deciding whether to own or lease properties. The new standard could cause companies that lease properties to prefer shorter lease terms, in an effort to reduce the leasing liability required to be recorded on their balance sheets. The new standard could also make lease renewal options less attractive, as, under certain circumstances, the rule would require a tenant to assume that a renewal right will be exercised and accrue a liability relating to the longer lease term.

Risks Related to the Real Estate Industry

Real estate investments are illiquid, and we may not be able to sell our Properties if and when we determine it is appropriate to do so.

Real estate generally cannot be sold quickly. We may not be able to dispose of our Properties promptly in response to economic or other conditions. In addition, provisions of the Internal Revenue Code of 1986, as amended (the "Code"), limit a REIT's ability to sell properties in some situations when it may be economically advantageous to do so, thereby adversely affecting returns to shareholders and adversely impacting our ability to meet our obligations to the holders of other securities.

We may experience economic harm if any damage to our Properties is not covered by insurance.

We believe all of our Properties are adequately insured with carriers that are adequately capitalized. However, we cannot guarantee that the limits of our current policies will be sufficient in the event of a catastrophe to our Properties or that carriers will be able to honor their obligations. Our existing property and liability policies expire during 2019. We cannot guarantee that we will be able to renew or duplicate our current coverages in adequate amounts or at reasonable prices.

We may suffer losses that are not covered under our comprehensive liability, fire, extended coverage and rental loss insurance policies. For example, we may not be insured for losses resulting from acts of war, certain acts of terrorism, or from certain liabilities. If an uninsured loss or a loss in excess of insured limits should occur, we would nevertheless remain liable for the loss, which could adversely affect cash flow from operations.

Table of Contents

We may experience economic harm as a result of the effects of climate change.

We cannot predict the future effects of climate change or how climate change may progress. However, the impact of climate change could have a material adverse effect on our properties, operating results and financial condition. Potential impacts of climate change could include changes in weather patterns affecting the frequency and intensity of storms and rising sea levels. To the extent that our properties or the regions in which they are located are adversely affected by these conditions, they may become less desirable to tenants. Climate change may also have indirect effects on our business by increasing the cost of, or decreasing the availability of, property insurance on terms we find acceptable, by increasing the cost of energy, by increasing the cost of snow removal at our properties, or by impacting our development activities. We may not be able to mitigate effectively any such effects, and our properties, operations or business may be adversely affected.

Potential liability for environmental contamination could result in substantial costs.

Under federal, state and local environmental laws, ordinances and regulations, we may be required to investigate and clean up the effects of releases of hazardous or toxic substances or petroleum products at our Properties simply because of our current or past ownership or operation of the real estate. If unidentified environmental problems arise, we may have to make substantial payments which could adversely affect our cash flow and our ability to make distributions to our shareholders because:


▪	as owner or operator, we may have to pay for property damage and for investigation and clean-up costs incurred in connection with the contamination


▪	the law typically imposes clean-up responsibility and liability regardless of whether the owner or operator knew of or caused the contamination


▪	even if more than one person may be responsible for the contamination, each person who shares legal liability under the environmental laws may be held responsible for all of the clean-up costs


▪	governmental entities and third parties may sue the owner or operator of a contaminated site for damages and costs

These costs could be substantial. The presence of hazardous or toxic substances or petroleum products or the failure to properly remediate contamination may materially and adversely affect our ability to borrow against, sell or rent an affected property. In addition, applicable environmental laws create liens on contaminated sites in favor of the government for damages and costs it incurs in connection with a contamination. Changes in laws increasing the potential liability for environmental conditions existing at our Properties may result in significant unanticipated expenditures.

Substantially all of the Company's properties and land were subject to environmental assessments obtained in contemplation of their acquisition by the Company or obtained by predecessor owners prior to the sale of the property or land to the Company. These assessments generally include a visual inspection of the properties and the surrounding areas, an examination of current and historical uses of the properties and the surrounding areas and a review of relevant state, federal and historical documents, but do not involve invasive techniques such as soil and ground water sampling. Where appropriate, on a property-by-property basis, our practice is to have these consultants conduct additional testing, including sampling for asbestos, for lead in drinking water, for soil contamination where underground storage tanks are or were located or where other past site usages create a potential environmental problem, and for contamination in groundwater. Even though these environmental assessments are conducted, there is still the risk that:


▪	the environmental assessments and updates will not identify all potential environmental liabilities


▪	a prior owner created a material environmental condition that is not known to us or the independent consultants preparing the assessments


▪	new environmental liabilities have developed since the environmental assessments were conducted


▪	future uses or conditions such as changes in applicable environmental laws and regulations could result in environmental liability for us

Indoor air quality issues can stem from inadequate ventilation, chemical contaminants from indoor or outdoor sources, pollen, viruses and bacteria and may necessitate remediation. Indoor exposure to chemical or biological contaminants above certain levels can be alleged to be connected to allergic reactions or other health effects and symptoms in susceptible individuals. If these conditions were to occur at one of our Properties, we may need to undertake a targeted remediation program, including without limitation, steps to increase indoor ventilation rates and eliminate sources of contaminants. Such remediation programs could be costly, necessitate the temporary relocation of some or all of the Property's tenants or require rehabilitation of the affected Property.

Our Properties may contain or develop harmful mold, which could lead to liability for adverse health effects and costs of remediating the problem.

Table of Contents

When excessive moisture accumulates in buildings or on building materials, mold growth may occur, particularly if the moisture problem remains undiscovered or is not addressed over a period of time. Some molds may produce airborne toxins or irritants and exposure to mold may cause a variety of adverse health effects and symptoms, including allergic or other reactions. As a result, the presence of significant mold at any of our Properties could require us to undertake a costly remediation program to contain or remove the mold from the affected Property. In addition, the presence of significant mold could expose us to liability from our tenants, employees of our tenants and others if property damage or health concerns arise.

Compliance with the Americans with Disabilities Act and fire, safety and other regulations may require us to make expenditures that adversely impact our operating results.

All of our Properties are required to comply with the Americans with Disabilities Act ("ADA"). The ADA generally requires that buildings be made accessible to people with disabilities. Compliance with the ADA requirements could require removal of access barriers, and non-compliance could result in imposition of fines by the United States government or an award of damages to private litigants, or both. Expenditures related to complying with the provisions of the ADA could adversely affect our results of operations and financial condition and our ability to make distributions to shareholders. In addition, we are required to operate our Properties in compliance with fire and safety regulations, building codes and other land use regulations, as they may be adopted by governmental agencies and bodies and become applicable to our Properties. We may be required to make substantial capital expenditures to comply with those requirements and these expenditures could have a material adverse effect on our operating results and financial condition, as well as our ability to make distributions to shareholders.

Terrorist attacks and other acts of violence or war may adversely impact our operating results and may affect markets on which our securities are traded.

Terrorist attacks against our Properties, or against the United States or United Kingdom or the interests of the United States or United Kingdom generally, may negatively affect our operations and investments in our securities. Attacks or armed conflicts could have a direct adverse impact on our Properties or operations through damage, destruction, loss or increased security costs. Any terrorism insurance that we obtain may be insufficient to cover the loss for damages to our Properties as a result of terrorist attacks.

Furthermore, any terrorist attacks or armed conflicts could result in increased volatility in or damage to financial markets in the United States or the United Kingdom or the worldwide economy. Adverse economic conditions could affect the ability of our tenants to pay rent, which could have an adverse impact on our operating results.

Risks Related to Our Organization and Structure

We have elected REIT status under the federal tax laws and could suffer adverse consequences if we fail to qualify as a REIT.

We have elected REIT status under federal tax laws and have taken the steps known to us to perfect that status, but we cannot be certain that we qualify or that we will remain qualified. Qualification as a REIT involves the application of highly technical and complex provisions of the Code, as to which there are only limited judicial or administrative interpretations. The complexity of these provisions and of the related regulations is greater in the case of a REIT that holds its assets in partnership form, as we do. Moreover, no assurance can be given that new tax laws will not significantly affect our qualification as a REIT or the federal income tax consequences of such qualification. New laws could be applied retroactively, which means that past operations could be found to be in violation, which would have a negative effect on the business.

If we fail to qualify as a REIT in any taxable year, the distributions to shareholders would not be deductible when computing taxable income. If this happened, we would be subject to federal income tax on our taxable income at regular corporate rates. Also, we could be prevented from qualifying as a REIT for the four years following the year in which we were disqualified. Further, if we requalified as a REIT after failing to qualify, we might have to pay the full corporate-level tax on any unrealized gain in our assets during the period we were not qualified as a REIT. We would then have to distribute to our shareholders the earnings we accumulated while we were not qualified as a REIT. These additional taxes would reduce our funds available for distribution to our shareholders. In addition, while we were disqualified as a REIT, we would not be required by the Code to make distributions to our shareholders. A failure by the Company to qualify as a REIT and the resulting requirement to pay taxes and interest (and perhaps penalties) would cause us to default under various agreements to which we are a party, including under our credit facilities, and would have a material adverse effect on our business, prospects, results of operations, earnings, financial condition and our ability to make distributions to shareholders.

Future economic, market, legal, tax or other considerations may lead our Board of Trustees to authorize the revocation of our election to qualify as a REIT. A revocation of our REIT status would require the consent of the holders of a majority of the voting interests of all of our outstanding Common Shares.

Certain trustees and officers of the Trust may not have the same interests as shareholders as to certain tax laws.

Certain trustees and officers of the Trust own Common Units. These units may be exchanged for our Common Shares. The trustees and officers who own those units and have not yet exchanged them for our Common Shares may suffer different and more adverse tax consequences than holders of our Common Shares suffer in certain situations:


▪	when certain of our Properties are sold


▪	when debt on those Properties is refinanced


▪	if we are involved in a tender offer or merger

Because these officers own Common Units and face different consequences than shareholders do, the Trust and those trustees and officers may have different objectives as to these transactions than shareholders do.

Certain aspects of our organization could have the effect of restricting or preventing a change of control of our Company, which could have an adverse effect on the price of our shares.

Our charter contains an ownership limit on shares. To qualify as a REIT, five or fewer individuals cannot own, directly or indirectly, more than 50% in value of the outstanding shares of beneficial interest. To this end, our Declaration of Trust, among other things, generally prohibits any holder of the Trust's shares from owning more than 5% of the Trust's outstanding shares of beneficial interest, unless that holder gets the consent from our Board of Trustees. This limitation could prevent the acquisition of control of the Company by a third party without the consent from our Board of Trustees.

We can issue preferred shares. Our Declaration of Trust authorizes our Board of Trustees to establish the preferences and rights of any shares issued. The issuance of preferred shares could have the effect of delaying, making more difficult or preventing a change of control of the Company, even if a change in control were in the shareholder's interest.

There are limitations on acquisition of and changes in control pursuant to, and fiduciary protections of the Board under Maryland law. The Maryland General Corporation Law ("MGCL") contains provisions which are applicable to the Trust as if the Trust were a corporation. Among these provisions is a section, referred to as the "control share acquisition statute," which eliminates the voting rights of shares acquired in quantities so as to constitute "control shares," as defined under the MGCL. The MGCL also contains provisions applicable to us that are referred to as the "business combination statute," which would generally limit business combinations between the Company and any 10% owners of the Trust's shares or any affiliate thereof. Further, Maryland law provides broad discretion to the Board with respect to its fiduciary duties in considering a change in control of our Company, including that the Board is subject to no greater level of scrutiny in considering a change in control transaction than with respect to any other act by the Board. Finally, the "unsolicited takeovers" provisions of the MGCL permit the Board, without shareholder approval and regardless of what is currently provided in our Declaration of Trust or By-Laws, to implement takeover defenses that our Company does not yet have, including permitting only the Board to fix the size of the Board and permitting only the Board to fill a vacancy on the Board. All of these provisions may have the effect of inhibiting a third party from making an acquisition proposal for our Company or of delaying, deferring or preventing a change in control of the Company under circumstances that otherwise could provide the holders of Common Shares with the opportunity to realize a premium over the then current market price.

Various factors out of our control could hurt the market value of our publicly traded securities.

The value of our publicly traded securities depends on various market conditions, which may change from time to time. In addition to general economic and market conditions and our particular financial condition and performance, the value of our publicly traded securities could be affected by, among other things, the extent of institutional investor interest in us and the market's opinion of REITs in general and, in particular, REITs that own and operate properties similar to ours.

The market value of the equity securities of a REIT may be based primarily upon the market's perception of the REIT's growth potential and its current and future cash distributions, and may be secondarily based upon factors such as the real estate market value of the underlying assets. The failure to meet the market's expectations with regard to future earnings and cash distributions likely would adversely affect the market price of publicly traded securities. Our payment of future dividends will be at the discretion of our Board of Trustees and will depend on numerous factors including our cash flow, financial condition and capital requirements, annual distribution requirements under the REIT provisions of the Code, the general economic environment and such other factors as our Board of Trustees deems relevant.

Rising market interest rates could make an investment in publicly traded securities less attractive. If market interest rates increase, purchasers of publicly traded securities may demand a higher annual yield on the price they pay for their securities. This could adversely affect the market price of publicly traded securities.

On December 22, 2017, H.R. 1, commonly referred to as the Tax Cuts and Jobs Act (the “Act”), was signed into law by President Donald J. Trump, making significant changes to the Internal Revenue Code of 1986, as amended (the "Code").

Relevant changes include, but are not limited to, the following:


•	Reduces the federal corporate income tax rate from 35% to 21% (including with respect to our taxable REIT subsidiaries (“TRSs”)) for tax years beginning after December 31, 2017;

•

Restricts the deductibility of interest expense by businesses (generally, to 30% of the business’ adjusted taxable income) except, among others, “real property businesses” electing out of such restriction; and while generally, we expect our business to qualify as a “real property business”, we have not yet determined whether the Company and/or our TRSs can and/or will make such an election going forward;


•	Reduces the rate of U.S. federal withholding tax on distributions made to non-U.S. shareholders by a REIT that are attributable to gains from the sale or exchange of U.S. real property interests from 35% to 21%;


•	Generally, reduces the highest marginal income tax rate for individuals to 37% from 39.6%;


•	Generally, allows a deduction for individuals equal to 20% of ordinary dividends distributed by a REIT (excluding capital gain dividends and qualified dividend income), generally resulting in a maximum effective federal income tax rate applicable to such dividends of 29.6% as compared to 37% prior to the enactment of this provision of the Act; and


•	Limits certain deductions for individuals, including deductions for state and local income taxes, and eliminates deductions for miscellaneous itemized deductions (including certain investment expenses).

Under the Act, many of the provisions, in particular those affecting individual taxpayers, expire at the end of 2025. While many of the provisions contained in the Act generally appear to be favorable with respect to REITs, the extensive changes to non-REIT provisions in the Code may have unanticipated effects on the Company and/or our shareholders. Moreover, Congressional leaders have recognized that the process of adopting extensive tax legislation in a short amount of time may have led to a need to amend or supplement the legislation which can only be accomplished through additional tax legislation. At this point, it is unclear whether Congress will address these issues or when the Treasury Department (“Treasury”) and/or the Internal Revenue Service (“IRS”) will issue administrative guidance.

As a result, the Company’s taxable income and/or the amount of distributions to our shareholders required in order to maintain our REIT status, and our relative tax advantage as a REIT, may significantly change and/or be adversely impacted over time. Further, the Act is a complex set of revisions to the current U.S. federal income tax laws which have the potential to impact certain classes of taxpayers and/or industries differently, and will require subsequent and substantial rulemaking, guidance and interpretation in a number of areas by both the Treasury and the IRS. The long-term impact of the Act on the overall economy, government revenues, our tenants, the Company and the overall real estate industry cannot be reasonably predicted at this early stage of the new law’s implementation. As a result, we cannot reasonably provide any assurance at this time that the Act will not adversely impact the Company, our shareholders and/or the price of our securities moving forward.

We do not have a shareholder rights plan but are not precluded from adopting one.

Although we do not have a shareholder rights plan, we are not prohibited from adopting, without shareholder approval, a shareholder rights plan that may discourage any potential acquirer from acquiring more than a specific percentage of our outstanding Common Shares since, upon this type of acquisition without approval of our Board of Trustees, all other common shareholders would have the right to purchase a specified amount of Common Shares at a substantial discount from market price.

Transactions by the Trust or the Operating Partnership could adversely affect debt holders.

Except with respect to several covenants limiting the incurrence of indebtedness and a covenant requiring the Operating Partnership to maintain a certain unencumbered total asset value, our indentures do not contain any additional provisions that would protect holders of the Operating Partnership's debt securities in the event of (i) a highly leveraged transaction involving the Operating Partnership, (ii) a change of control or (iii) certain reorganizations, restructurings, mergers or similar transactions involving the Operating Partnership or the Trust.

PART II

ITEM 5. MARKET FOR THE REGISTRANTS' COMMON EQUITY, RELATED SHAREHOLDER MATTERS AND RELATED ISSUER PURCHASES OF EQUITY SECURITIES

The Common Shares are traded on the New York Stock Exchange under the symbol "LPT." There is no established public trading market for the Common Units.

As of February 14, 2019, the Common Shares were held by 820 holders of record. Since its initial public offering in 1994, the Company has paid regular and uninterrupted quarterly dividends.

In February 2019, the Board of Trustees declared a dividend of $0.41 per share to be paid in April 2019. The payment of future dividends by the Company will be at the discretion of the Board of Trustees and will depend on numerous factors including the Company's cash flow, its financial condition, capital requirements, annual distribution requirements under the REIT provisions of the Code, the general economic environment and such other factors as the Board of Trustees deems relevant. The Company’s Board of Trustees reviews the dividend quarterly, and there can be no assurance about the amount of future quarterly distribution payments.

The following line graph compares the cumulative total shareholder return on Common Shares for the period beginning December 31, 2013 and ended December 31, 2018 with the cumulative total return on the Standard and Poor's 500 Stock Index ("S&P 500") and the NAREIT Equity REIT Total Return Index ("NAREIT Index") over the same period. Total return values for the S&P 500, the NAREIT Index and the Company's Common Shares were calculated based on cumulative total return assuming the investment of $100 in the NAREIT Index, the S&P 500 and the Company's Common Shares on December 31, 2013, and assuming reinvestment of dividends in all cases.

The performance graph above is being furnished as part of this Annual Report solely in accordance with the requirement under Rule 14a-3(b)(9) to furnish the Company’s stockholders with such information and, therefore, is not deemed to be filed, or incorporated by reference in any filing, by the Company or the Operating Partnership under the Securities Act of 1933 or the Securities Exchange Act of 1934.

The National Association of Real Estate Investment Trusts ("NAREIT") has issued a standard definition for Funds from operations (as defined below). The Securities and Exchange Commission has agreed to the disclosure of this non-US GAAP financial measure on a per share basis in its Release No. 34-47226, Conditions for Use of Non-US GAAP Financial Measures. The Company believes that the calculation of NAREIT Funds from operations is helpful to investors and management as it is a measure of the Company's operating performance that excludes depreciation and amortization and gains and losses from property dispositions. As a result, year over year comparison of NAREIT Funds from operations reflects the impact on operations from trends in occupancy rates, rental rates, operating costs, development activities, general and administrative expenses, and interest costs, providing perspective not immediately apparent from net income. In addition, management believes that NAREIT Funds from operations provides useful information to the investment community about the Company's financial performance when compared to other REITs since NAREIT Funds from operations is generally recognized as the standard for reporting the operating performance of a REIT. NAREIT Funds from operations available to common shareholders is defined by NAREIT as net income (computed in accordance with generally accepted accounting principles ("US GAAP")), excluding gains (or losses) from sales of property and impairment - real estate assets, plus depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. NAREIT Funds from operations available to common shareholders does not represent net income or cash flows from operations as defined by US GAAP and does not necessarily indicate that cash flows will be sufficient to fund cash needs. It should not be considered as an alternative to net income as an indicator of the Company's operating performance or to cash flows as a measure of liquidity. NAREIT Funds from operations available to common shareholders also does not represent cash flows generated from operating, investing or financing activities as defined by US GAAP. A reconciliation of NAREIT Funds from operations to net income may be found in Item 7 - Management's Discussion and Analysis of Financial Condition and Results of Operations.

Item 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

Liberty Property Trust (the “Trust”) is a self-administered and self-managed Maryland real estate investment trust (“REIT”). Substantially all of the Trust’s assets are owned directly or indirectly, and substantially all of the Trust’s operations are conducted directly or indirectly, by its subsidiary, Liberty Property Limited Partnership, a Pennsylvania limited partnership (the “Operating Partnership” and, collectively with the Trust and their consolidated subsidiaries, the “Company”).

The Company owns and operates industrial properties in the United States nationally, as well as in the United Kingdom.

As previously reported, and as further summarized below, the Company undertook several significant transactions in recent years consistent with its strategy to divest its remaining office Properties (other than its headquarters) and focus its efforts and capital solely on its industrial platform, which favors industrial properties and markets with strong demographic and economic fundamentals. In furtherance of this strategy, the Company has substantially divested of its suburban office Properties, and expects to divest its remaining metro-office Properties over the next few years. The Company plans to reinvest the proceeds of these divestments in acquisitions in targeted industrial markets and new development. The Company anticipates that this strategy will yield benefits over time, including a higher rate of rental growth and a lower level of lease transaction costs and other capital costs for industrial properties as opposed to office properties. The Company believes that this strategy has resulted in an improvement in the average quality and geographic location of its properties. The Company also believes that the benefits of the strategy will outweigh the short-term reduction in operating cash flow resulting from the disposition of its office Properties. There can be no assurance, however, that the benefits of the Company’s strategy will be realized.

As of December 31, 2018 the Company owned the following "Properties in Operation" (square feet in thousands):



	Number of Operating Industrial Properties	Number of Operating Office Properties	Total Number of Properties	Total Square Feet
"Wholly Owned Properties in Operation"	480	22	502	91,248
"JV Properties in Operation" (at 100%)	48	18	66	14,853
"Properties in Operation"	528	40	568	106,101

As of December 31, 2018 the Company owned the following "Properties under Development" and "Properties held for Redevelopment/Value-Added" (square feet upon completion in thousands):



	Number of Properties	Total Square Feet
"Wholly Owned Properties under Development"	29	8,195
"JV Properties under Development" (at 100%)	2	134	⁽¹⁾
"Properties under Development"	31	8,329

"Wholly Owned Properties held for Redevelopment/Value-Added"	7	868
"JV Properties held for Redevelopment/Value-Added" (at 100%)	1	48
"Properties held for Redevelopment/Value-Added"	8	916

(1) Including a 217-room hotel, which is excluded from square footage total.

The Company also owned 1,283 acres of developable land and through unconsolidated joint ventures 339 acres of developable land substantially all of which is zoned for commercial use.

The Company focuses on creating value for shareholders and increasing profitability and cash flow. With respect to its Properties in Operation, the Company endeavors to maintain high occupancy levels while maximizing rental rates and controlling costs. The Company pursues development opportunities that it believes will create value and yield acceptable returns. The Company also acquires properties that it believes will create long-term value, and disposes of properties that no longer fit within the Company’s strategic objectives or in situations where it can optimize cash proceeds.

The Company’s operating results depend primarily upon income from rental operations and are substantially influenced by rental demand for the Properties in Operation. During the year ended December 31, 2018, straight line rents on renewal and replacement leases were on average 15.4% higher than rents on expiring leases. During the year ended December 31, 2018, the Company leased 22.9 million square feet and, as of that date, attained occupancy of 95.9% for the Wholly Owned Properties in Operation and 98.9% for the JV Properties in Operation for a combined occupancy of 96.3% for the Properties in Operation. At December 31, 2017, occupancy for the Wholly Owned Properties in Operation was 97.0% and for the JV Properties in Operation was 96.5% for a combined occupancy for the Properties in Operation of 96.9%. During the third quarter of 2018, the Sears Holdings Corporation filed for reorganization under Chapter 11 of the federal bankruptcy laws. If the Company's leases with Sears are rejected it could have a negative impact on operating results. This tenant represents 0.8% of square feet of the Company's Properties in Operation and 0.8% of Net Rent. For the tenants in the JV Properties in Operation, Net Rent reflects the Company's ownership percentage of the respective joint ventures.

Based on the Company's current outlook, the Company anticipates that property level operating income for the Same Store (defined below) group of industrial properties will increase for the full year 2019, compared to 2018, driven primarily by new and renewal leases being executed at higher rental rates than those of expiring leases. The Company expects Same Store occupancy levels to remain relatively consistent with those in 2018.

The assumptions presented above are forward-looking and are based on the Company’s future view of market and general economic conditions, as well as other risks outlined below under the caption “Forward-Looking Statements.” There can be no assurance that the Company’s actual results will not differ materially from assumptions set forth above. The Company assumes no obligation to update these assumptions in the future.

Wholly Owned Capital Activity

Acquisitions

During the year ended December 31, 2018, the Company acquired 16 operating properties for an aggregate purchase price of $494.3 million. These properties contain an aggregate of 4.1 million square feet of leaseable space and were 61.0% leased as of December 31, 2018. The Company also acquired 12 parcels of land totaling 274.9 acres for an aggregate purchase price of $138.3 million.

Dispositions

During the year ended December 31, 2018, the Company sold 39 Wholly Owned Properties containing an aggregate of 3.4 million square feet, development rights in the UK, and 79.1 acres of land for aggregate proceeds of $873.4 million.

Development

During the year ended December 31, 2018, the Company brought into service 16 Wholly Owned Properties under Development representing 4.7 million square feet and a Total Investment of $434.7 million. As of December 31, 2018, the Company had 29 Wholly Owned Properties under Development, which are expected to comprise, upon completion, 8.2 million square feet and are expected to represent a Total Investment of $735.0 million. These Wholly Owned Properties under Development were 36.3% pre-leased as of December 31, 2018.

Unconsolidated Joint Venture Activity

The Company periodically enters into unconsolidated joint venture relationships in connection with the execution of its real estate operating strategy.

Acquisitions/Dispositions

During the year ended December 31, 2018, none of the unconsolidated joint ventures in which the Company holds an interest acquired or sold any operating properties or land parcels.

Consistent with the Company's strategy, from time to time the Company may consider selling assets to or purchasing assets from an unconsolidated joint venture in which the Company holds an interest.

Development

Table of Contents

During the year ended December 31, 2018, an unconsolidated joint venture in which the Company held an interest brought into service a build-to-suit project totaling 302,000 square feet and representing a Total Investment of $21.0 million. As of December 31, 2018, this completed development property was 100.0% leased. As of December 31, 2018, the Company had one JV Property under Development, which is expected to comprise, upon completion, 134,000 square feet and is expected to represent a Total Investment of $10.3 million. This JV Property under Development was 54.6% pre-leased as of December 31, 2018.

Forward-Looking Statements

When used throughout this report, the words "believes," "anticipates," "estimates" and "expects" and similar expressions are intended to identify forward-looking statements. Such statements indicate that assumptions have been used that are subject to a number of risks and uncertainties that could cause actual financial results or management plans and objectives to differ materially from those projected or expressed herein, including: the effect of national and regional economic conditions; rental demand; the Company's ability to continue to implement its plans for repositioning the portfolio; the Company's ability to identify, and enter into agreements with, suitable joint venture partners in situations where it believes such arrangements are advantageous; the Company's ability to identify and secure additional properties and sites, both for itself and the joint ventures to which it is a party, that meet its criteria for acquisition or development; the availability and cost of capital; the effect of prevailing market interest rates; risks related to the integration of the operations of entities that we have acquired or may acquire; risks related to litigation; and other risks described in Item 1A. Risk Factors and, from time to time, in the Company's filings with the SEC. Given these uncertainties, readers are cautioned not to place undue reliance on such statements.

Critical Accounting Policies and Estimates

The Company's discussion and analysis of its financial condition and results of operations are based upon the Company's consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles ("US GAAP"). The preparation of these financial statements requires the Company to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. The Company bases these estimates, judgments and assumptions on historical experience and on other factors that are believed to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.

The following critical accounting policies discussion reflects what the Company believes are the more significant estimates, assumptions and judgments used in the preparation of its Consolidated Financial Statements. This discussion of critical accounting policies is intended to supplement the description of the accounting policies in the footnotes to the Company's Consolidated Financial Statements and to provide additional insight into the information used by management when evaluating significant estimates, assumptions and judgments. For further discussion of our significant accounting policies, see Note 2 to the Consolidated Financial Statements included in this report.

Capitalized Costs

Acquisition costs related to the purchase of operating properties and land are capitalized and included in net real estate. Prior to the adoption of ASU 2017-01, Clarifying the Definition of Business, the Company expensed acquisition costs related to the purchase of operating properties with in-place tenants. For the nine months ended September 30, 2016 acquisition costs expensed were $172,000.

The Company capitalizes costs associated with development and redevelopment activities, capital improvements, tenant improvements, and leasing activities, including compensation costs. Expenditures directly related to the improvement of real estate, including interest and other costs capitalized on development and redevelopment projects and land being readied for development, are included in net real estate and are stated at cost. The Company considers a development property substantially complete upon the completion of tenant build-out, but no later than one year after the completion of major construction activity. These capitalized costs include pre-construction costs essential to the development of the property, construction costs, interest costs, real estate taxes, development related compensation and other costs incurred during the period of development. The determination to capitalize rather than expense costs requires the Company to evaluate the status of the development activity. The total of capitalized compensation costs directly related to the development, redevelopment, capital improvements and tenant improvements for the years ended December 31, 2018, 2017 and 2016 was $7.1 million, $5.5 million and $7.2 million, respectively.

Table of Contents

Certain employees of the Company are compensated for leasing services related to the Company's properties. The compensation directly related to signed leases is capitalized and amortized as a deferred leasing cost. The total of this capitalized compensation was $2.7 million, $3.6 million and $3.8 million for the years ended December 31, 2018, 2017 and 2016, respectively.

Capitalized interest for the years ended December 31, 2018, 2017 and 2016 was $24.5 million, $21.0 million and $24.1 million, respectively.

Revenue Recognition

Rental revenue is recognized on a straight line basis over the noncancelable terms of the respective leases. Deferred rent receivable represents the amount by which straight line rental revenue exceeds rents currently billed in accordance with the lease agreements. Above-market and below-market lease values for acquired properties are recorded based on the present value (using a discount rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to each in-place lease and (ii) management's estimate of fair market lease rates for each corresponding in-place lease. The capitalized above or below-market lease values are amortized as a component of rental revenue over the remaining term of the respective leases and any bargain renewal option periods, where appropriate.

The Company recognizes development service fee income on a variable basis as a percentage of costs incurred on third party development contracts. Property development services, which are a single performance obligation, continue to be satisfied and recognized over time. The Company measures its progress toward completing the performance obligation under each

arrangement. The measurement of the transfer of value to the customer for these services utilizes the input method (actual costs incurred against anticipated project costs) since this method best depicts the actual transfer of value promised to the customer. Estimated expected losses on such contracts are accrued in the period in which they are determinable. The total amount of consideration to be received from these projects is assessed on a quarterly basis.

The Company is required to make judgments regarding estimated cost overruns that may be incurred relating to an agreement to develop, for a fee, the Comcast Technology Center in Philadelphia, PA (see note 7 to the consolidated financial statements where discussed further). Under this development agreement, the Company has accrued $67.1 million as of December 31, 2018 relating to its development cost guarantees to the joint ventures which own the project and in which the Company holds an interest. There can be no assurances that amounts incurred, including as a result of claims that have been asserted by the third party contractor and certain subcontractors, will not exceed these estimates. The Company is not able to reasonably estimate the amount of additional expenses, if any, that it may incur as a result of such claims, and accordingly any potential exposure of the Company for such claims is not included within the accrual described above. If the Company were to incur additional expenses in connection with its development cost guarantee or in connection with any such claims, such amounts would be accrued when they are determined to be probable of being incurred and are reasonably estimable, and could be material to the Company's results of operations in future periods. If the Company were to subsequently recover any of the cost overruns initially funded by the Company, such recoveries would be recorded when and if realized in future periods.

Allowance for Doubtful Accounts

The Company continually monitors the liquidity and creditworthiness of its tenants. Based on these reviews, provisions are established, and an allowance for doubtful accounts for estimated losses resulting from the inability of its tenants to make required rental payments is maintained. As of December 31, 2018 and 2017, the Company's allowance for doubtful accounts totaled $6.4 million and $6.6 million, respectively. The Company recognized bad debt expense of $1.4 million, $0.6 million and $0.6 million for the years ended December 31, 2018, 2017 and 2016, respectively.

Table of Contents

Impairment of Real Estate

The Company evaluates its real estate investments upon the occurrence of significant adverse changes in operations to assess whether any impairment indicators are present that could affect the recovery of the recorded value. Indicators the Company uses to determine whether an impairment evaluation is necessary include the low occupancy level of the property, holding period for the property, strategic decisions regarding future development plans for a property under development and land held for development and other market factors. If impairment indicators are present, the Company performs an undiscounted cash flow analysis and compares the net carrying amount of the property to the property's estimated undiscounted future cash flow over the anticipated holding period. The Company assesses the expected undiscounted cash flows based upon a number of assumptions that are subject to economic and market uncertainties including, among others, demand for space, competition for tenants, current market rental rates, changes in market rental rates, operating costs, capitalization rates and holding periods. For these assumptions, the Company considers its experience and historical performance in the various markets and data provided by market research organizations. If any real estate investment is considered impaired, the carrying value of the property is written down to its estimated fair value.If held for sale, a property is not considered impaired unless its estimated fair value (less costs to sell) is less than the property's book value at the balance sheet date. The Company estimates fair value based on the discounting of future expected cash flows at a risk adjusted interest rate. During the years ended December 31, 2018, 2017 and 2016, the Company recognized impairment losses of $39.7 million, $10.6 million and $3.9 million, respectively. The determination of whether an impairment exists requires the Company to make estimates, judgments and assumptions about the future cash flows. The Company has applied reasonable estimates and judgments in determining the level of impairments recognized. Should external or internal circumstances change requiring the need to shorten the holding periods or adjust the estimated future cash flows of the Company’s assets, the Company could be required to record impairment charges in the future.

Intangibles

The Company allocates the purchase price of real estate acquired to land, building and improvements and intangibles based on the relative fair value of each component. The value ascribed to in-place leases is based on the rental rates for the existing leases compared to the Company's estimate of the market lease rates for leases of similar terms and present valuing the difference based on an interest rate which reflects the risks associated with the leases acquired. Origination values are also assigned to in-place leases, and, where appropriate, value is assigned to customer relationships. Origination cost estimates include the costs to execute leases with terms similar to the remaining lease terms of the in-place leases, including leasing commissions, legal and other related expenses. Additionally, the Company estimates carrying costs during the expected lease-up periods including real estate taxes, other operating expenses and lost rentals at contractual rates. Such amounts are also included in origination costs. The amounts allocated to the intangible relating to in-place leases, which are included in deferred financing and leasing costs or in other liabilities in the accompanying consolidated balance sheets, are amortized to rental income for market rental rate intangibles and to depreciation and amortization for origination costs on a straight line basis over the remaining term of the related leases. In the event that a tenant terminates its lease, the unamortized portion of the intangible is written off.

Investments in Unconsolidated Joint Ventures

The Company analyzes its investments in joint ventures to determine if the joint venture is considered a variable interest entity and would require consolidation. The Company accounts for its investments in unconsolidated joint ventures using the equity method of accounting as the Company exercises significant influence over, but does not control, these entities. These investments are recorded initially at cost and subsequently adjusted for equity in earnings and cash contributions and distributions.

On a periodic basis, management assesses whether there are any indicators that the value of the Company's investments in unconsolidated joint ventures may be impaired. An investment is impaired if management's estimate of the value of the investment is less than the carrying value of the investment, and such decline in value is deemed to be other than temporary. To the extent impairment has occurred, the loss is measured as the excess of the carrying amount of the investment over the estimated fair value of the investment.

Management estimated the fair value of its ownership interest in the joint ventures considering the estimated fair value of the real estate assets owned by the joint ventures and the related indebtedness as well as the working capital assets and liabilities of the joint ventures and the terms of the related joint venture agreements. The Company's estimates of fair value of the real estate assets are based on a discounted cash flow analysis incorporating a number of assumptions that are subject to economic and market uncertainties including, among others, demand for space, competition for tenants, current market rental rates, changes in market rental rates, operating costs, capitalization rates, holding periods and discount rates. For these assumptions, the Company considered its experience and historical performance in the various markets and data provided by market research organizations. In assessing whether an impairment is other-than-temporary, the Company considers several factors. The longevity and severity of the impairment are considered as well as the expected time for recovery of value to occur, if ever.

Table of Contents

During the years ended December 31, 2018 and 2017 the Company concluded that certain of the properties owned by the Liberty Washington, LP joint venture were impaired and the joint venture recorded an impairment charge. The Company's share of these impairment charges were $6.3 million and $4.0 million, respectively, and are reflected in equity in earnings of unconsolidated joint ventures in the Company's 2018 and 2017 consolidated statements of comprehensive income.

There were no impairments recorded by the unconsolidated joint ventures in which the Company held an interest during the year ended December 31, 2016.

Derivative Instruments and Hedging Activities

Derivative instruments and hedging activities require management to make judgments on the nature of its derivatives and their effectiveness as hedges. These judgments determine if the changes in fair value of the derivative instruments are reported in the consolidated statements of comprehensive income as a component of net income or as a component of other comprehensive income and as a component of equity on the Consolidated Balance Sheets. While management believes its judgments are reasonable, a change in a derivative’s effectiveness as a hedge could materially affect expenses, net income and equity.

Results of Operations

The following discussion is based on the consolidated financial statements of the Company. It compares the results of operations of the Company for the year ended December 31, 2018 with the results of operations of the Company for the year ended December 31, 2017, and the results of operations of the Company for the year ended December 31, 2017 with the results of operations of the Company for the year ended December 31, 2016. As a result of the varying levels of development, acquisition and disposition activities by the Company in 2018, 2017 and 2016, the overall operating results of the Company during such periods are not directly comparable. However, certain data, including the Same Store (as defined below) comparison, do lend themselves to direct comparison.

This information should be read in conjunction with the accompanying consolidated financial statements and notes included elsewhere in this report.

Comparison of Year Ended December 31, 2018 to Year Ended December 31, 2017

Rental Revenue

Rental revenue was $480.4 million for the year ended December 31, 2018 compared to $446.5 million for the same period in 2017. This increase of $33.9 million was primarily due to increased rental revenue related to acquisitions and completed development properties and an increase of $13.0 million related to the Company's Industrial Same Store portfolio (see below).

Operating Expense Reimbursement

Operating expense reimbursement was $151.3 million for the year ended December 31, 2018 compared to $136.2 million for the same period in 2017. This increase of $15.1 million was primarily due to an increase in rental property expense and real estate taxes (as detailed below).

Rental Property Expense

Rental property expense was $62.3 million for the year ended December 31, 2018 compared to $57.6 million for the same period in 2017. This increase of $4.7 million resulted from the additional expense for acquisition and completed development properties and an increase of $3.0 million related to increased costs for the Company's Industrial Same Store properties. Rental property expense includes utilities, insurance, janitorial, landscaping, snow removal and other costs necessary to maintain a property.

Real Estate Taxes

Real estate taxes were $91.7 million for the year ended December 31, 2018 compared to $83.2 million for the same period in 2017. This increase of $8.5 million was primarily due to increased real estate taxes for acquisitions and completed development properties and an increase of $3.1 million related to higher real estate tax assessments for the Company's Industrial Same Store properties.

Segments

The Company evaluates the performance of the Wholly Owned Properties in Operation in terms of net operating income by reportable segment (see Note 18 to the Company’s Consolidated Financial Statements for a reconciliation of this measure to net income).

Table of Contents

Development Service Fee Income and Expense

Development Service fee activity was a net loss of $61.6 million and $3.1 million during the years ended December 31, 2018 and 2017, respectively. This increase was primarily due to additional expenses the Company accrued in 2018 in its Philadelphia reportable segment. See Note 7 to the Company's financial statements.

General and Administrative

General and administrative expenses decreased to $53.8 million for the year ended December 31, 2018 compared to $56.2 million for the year ended December 31, 2017. This decrease was primarily due to decreases in incentive compensation expense.

General and administrative expenses include salaries, wages and incentive compensation for general and administrative staff along with related costs, consulting, marketing, public company expenses and other general and administrative costs.

Other Operating Expenses

Other operating expenses increased to $12.0 million for the year ended December 31, 2018 compared to $6.2 million for the year ended December 31, 2017. This increase was primarily due to costs incurred in connection with the Company's implementation of new financial and operating systems and additional severance costs associated with a reduction in head count associated with real estate sales. Offsetting these increases is a reduction in expensed pursuit costs.

Depreciation and Amortization

Depreciation and amortization increased to $169.7 million for the year ended December 31, 2018 from $162.7 million for the year ended December 31, 2017. This increase was primarily due to depreciation and amortization related to acquisitions and completed development properties since January 1, 2017.

Impairment - Real Estate Assets

Impairment - real estate assets increased to $32.4 million for the year ended December 31, 2018, as compared to $3.9 million for year ended December 31, 2017. In 2018 the Company recognized $32.4 million in impairment charges related to land in its Philadelphia, Florida, Chicago/Minneapolis and SE Pennsylvania reportable segments. In 2017, the Company recognized an impairment charge related to land held for development in the Company's Houston reportable segment. This property was subsequently sold. See Note 19 to the Company's financial statements.

Interest Expense

Interest expense increased to $89.6 million for the year ended December 31, 2018 from $84.2 million for the year ended December 31, 2017. This increase was due to the increase in the average debt outstanding to $2,974.0 million for the year ended December 31, 2018 from $2,756.0 million for the year ended December 31, 2017. The increase was partially offset by an increase in interest capitalized to $24.5 million for the year ended December 31, 2018 compared to $21.0 million for the year ended December 31, 2017 as well as a decrease in the weighted average interest rate to 3.8% for the year ended December 31, 2018 from 3.9% for the year ended December 31, 2017.

Equity in Earnings of Unconsolidated Joint Ventures

Equity in earnings of unconsolidated joint ventures increased to $21.4 million for the year ended December 31, 2018 compared to $17.2 million for the year ended December 31, 2017. This increase was primarily due to the Company's share of results from operations for a completed development building in an unconsolidated joint venture in which the Company holds an interest which was brought into service in January 2018. Additionally, the Company and its partner repaid third party joint venture debt resulting in a decrease in interest expense for another joint venture. Finally, offsetting these increases in joint venture net income is the Company's $6.3 million share of an impairment taken in a joint venture.

Equity in earnings of unconsolidated joint ventures was also impacted by changes in the gain on the sale of land leasehold interests by an unconsolidated joint venture in which the Company holds an interest. The Company's share of these gains was $5.8 million for the year ended December 31, 2018 compared to $8.0 million for the year ended December 31, 2017.

Other

Gain on property dispositions decreased to $81.5 million for the year ended December 31, 2018 from $100.4 million for the year ended December 31, 2017. This decrease resulted from the volume and composition of sales in 2018 as compared to 2017.

Changes in discontinued operations are reflective of the period of time the properties were held during the respective periods. To the extent that a property is sold, or completed and stabilized during a period, it will only impact the results of such period prior to being sold or completed and stabilized, as the case may be. There were 37 properties classified as discontinued operations and sold during the year ended December 31, 2018 and two properties were classified as discontinued operations and sold during the year ended December 31, 2017.

As a result of the foregoing, the Company’s net income increased to $492.6 million for the year ended December 31, 2018 from $290.1 million for the year ended December 31, 2017.

Comparison of Year Ended December 31, 2017 to Year Ended December 31, 2016

Rental Revenue

Rental revenue was $446.5 million for the year ended December 31, 2017 compared to $495.1 million for the same period in 2016. This decrease of $48.6 million was primarily due to the net result of decreased rental revenue related to property dispositions since January 1, 2016, offset by increased rental revenue related to acquisitions and completed development for the same comparative periods and an increase of $9.6 million related to the Company's Prior Year Industrial Same Store portfolio (see below).

Operating Expense Reimbursement

Operating expense reimbursement was $136.2 million for the year ended December 31, 2017 compared to $167.3 million for the same period in 2016. This decrease of $31.1 million was primarily due to lower reimbursements associated with the property dispositions since January 1, 2016.

Rental Property Expense

Rental property expense was $57.6 million for the year ended December 31, 2017 compared to $88.7 million for the same period in 2016. This decrease of $31.1 million was primarily due to a reduction in expense resulting from the sale of suburban office and high finish flex properties partially offset by increased expenses resulting from the acquisition and completed development of industrial properties. Rental property expense includes utilities, insurance, janitorial, landscaping, snow removal and other costs necessary to maintain a property.

Real Estate Taxes

Table of Contents

Real estate taxes were $83.2 million for the year ended December 31, 2017 compared to $92.9 million for the same period in 2016. This decrease of $9.7 million was primarily due to the net result of decreased real estate taxes related to property dispositions since January 1, 2016.

Development Service Fee Income and Expense

In the fourth quarter of 2016, the Company entered into an agreement relating to the fee development of an office building at its Camden Waterfront project in Camden, NJ. Project revenues and related costs and expenses are presented on a gross basis as "Development service fee income" and "Development service fee expense" in the Consolidated Statements of Comprehensive Income. Additionally, at the same time, the Company began classifying development fees and expenses relating to its fee development arrangements for certain unconsolidated joint venture projects in a manner consistent with the Camden Waterfront project described above. Previously, development service fee income relating to the Company's unconsolidated joint ventures had been classified as other income and development service fee expense had been classified as general and administrative expense in amounts as follows:

Table of Contents



	Nine months ended
	September 30, 2016
Other income	$	3,789
General and administrative expense	$	3,210

Development Service fee activity was a net loss of $3.1 during the year ended December 31, 2017 as compared to a net gain of $0.8 million for the year ended December 31, 2016. This decrease was primarily due to additional expenses the Company accrued in 2017 in its Philadelphia reportable segment.

General and Administrative

General and administrative expenses decreased to $56.2 million for the year ended December 31, 2017 compared to $63.1 million for the year ended December 31, 2016. This decrease was partially due to certain expenses which were classified as development service fee expense on the Company's consolidated statements of comprehensive income for the year ended December 31, 2017 and the partial year ended December 31, 2016, as described above. The decrease was also partially due to a decrease in compensation costs.

Other Operating Expenses

Other operating expenses increased to $6.2 million for the year ended December 31, 2017 compared to $5.0 million for the year ended December 31, 2016. This increase was primarily due to expense relating to the write-off of costs associated with certain planned development projects which were terminated. Partially offsetting this amount was less severance costs incurred in 2017 versus 2016.

Depreciation and Amortization

Depreciation and amortization decreased to $162.7 million for the year ended December 31, 2017 from $191.4 million for the year ended December 31, 2016. This decrease was primarily due to the net result of decreased depreciation and amortization related to property dispositions since January 1, 2016 offset by increased depreciation and amortization related to acquisitions and completed development for the same period. The decrease was also due to a reduction in amortization of in-place lease intangibles.

Impairment - Real Estate Assets

Impairment - real estate assets remained unchanged at $3.9 million for the years ended December 31, 2017 and December 31, 2016. In 2016, the Company recognized impairments related to certain properties in the Company's Chicago/Minneapolis reportable segment. These properties were subsequently sold. In 2017, the Company recognized an impairment charge related to land held for development in the Company's Houston reportable segment. This property was subsequently sold.

Interest Expense

Interest expense decreased to $84.2 million for the year ended December 31, 2017 from $105.1 million for the year ended December 31, 2016. This decrease was due to the decrease in the average debt outstanding to $2,756.0 million for the year ended December 31, 2017 from $3,077.7 million for the year ended December 31, 2016 as well as a decrease in the weighted average interest rate to 3.9% for the year ended December 31, 2017 from 4.2% for the year ended December 31, 2016. The decrease was partially offset by a decrease in interest capitalized to $21.0 million for the year ended December 31, 2017 compared to $24.1 million for the year ended December 31, 2016.

Equity in Earnings of Unconsolidated Joint Ventures

Equity in earnings of unconsolidated joint ventures decreased to $17.2 million for the year ended December 31, 2017 compared to $22.0 million for the year ended December 31, 2016. This decrease was primarily due to a decrease in gain on sale of operating properties, a decrease in gain on debt forgiveness and an increase in impairment charges - real estate assets by unconsolidated joint ventures in which the Company holds an interest. The Company's share of recognized gain was $7.3 million for the year ended December 31, 2016 compared to $3.0 million for 2017. The Company's share of debt forgiveness gains was $4.2 million for the year ended December 31, 2016. There were no such gains in 2017. The Company's share of impairment charges - real estate assets was $4.0 million for the year ended December 31, 2017. There were no such charges in 2016.

Other

Gain on property dispositions decreased to $100.4 million for the year ended December 31, 2017 from $219.3 million for the year ended December 31, 2016. This decrease resulted from the volume and composition of sales in 2017 as compared to 2016.

To the extent that a property is sold, or completed and stabilized during a period, it will only impact the results of such period prior to being sold or completed and stabilized, as the case may be. There were two properties classified as discontinued operations and sold during the year ended December 31, 2017.

As a result of the foregoing, the Company’s net income decreased to $290.0 million for the year ended December 31, 2017 from $366.1 million for the year ended December 31, 2016.

Liquidity and Capital Resources

Overview

The Company seeks to maintain a conservative balance sheet and pursue a strategy of financial flexibility. The Company's liquidity requirements include operating and general and administrative expenses, shareholder distributions, funding its investment in development properties and joint ventures and satisfying interest requirements and debt maturities. The Company believes that proceeds from operating activities, asset sales, its available cash, borrowing capacity from its Credit Facilities (as defined below) and its other sources of capital including the public debt and equity markets will provide it with sufficient funds to satisfy these obligations.

Activity

As of December 31, 2018, the Company had cash and cash equivalents of $95.8 million, including $10.9 million in restricted cash.

Net cash provided by operating activities increased to $383.5 million for the year ended December 31, 2018 from $336.6 million for the year ended December 31, 2017. This $46.9 million increase was primarily due to fluctuations in operating assets and

Table of Contents

liabilities. Net cash flow provided by operating activities is the primary source of liquidity to fund dividends to shareholders, recurring capital expenditures and leasing transaction costs for the Company’s Wholly Owned Properties in Operation.

Net cash used in investing activities decreased to $255.1 million for the year ended December 31, 2018 from $465.7 million for the year ended December 31, 2017. This $210.6 million difference was primarily due to the change in net proceeds from dispositions less cash paid for acquisitions which was $351.9 million in 2018 as compared to $123.5 million in 2017.

Net cash used in financing activities was $55.5 million for the year ended December 31, 2018 compared to net cash provided by financing activities of $96.2 million for the year ended December 31, 2017. This $151.7 million change was primarily due to net debt repayment activity associated with the net dispositions and acquisitions activity described above. Net cash used in financing activities includes proceeds from the issuance of equity and debt, net of debt repayments, equity repurchases and shareholder distributions.

The Company is a party to a credit facility with a maximum availability of $800 million (the "Facility") and a working capital line of credit for $30 million (the "Credit Facilities"). The Company also has a fully drawn delayed draw term loan (the "DDTL") facility for aggregate borrowings of $100 million (together the "Facilities"). The Facilities expire in October 2021 and have two six-month extensions at the Company's option. The interest rate on borrowings under the Facilities fluctuates based upon ratings from Moody's Investor Services, Inc., Standard and Poor's Ratings Group and Fitch, Inc. Based upon the Company’s current credit ratings, borrowings under the Credit Facilities bear interest at LIBOR plus 0.875%. There is also a 0.15% annual facility fee on the aggregate loan commitments of the Credit Facilities. The DDTL currently bears interest at LIBOR plus 0.95%. The Facility contains a competitive bid option, whereby participating lenders bid on the interest rate to be charged. This feature is available for up to 50% of the amount of the Facility. As of December 31, 2018, the Company had $411.8 million outstanding borrowings and $8.3 million of letters of credit issued under the Facilities.

In September 2016, the Company issued $400 million of 3.25% senior unsecured notes due 2026. The Company used a substantial portion of the net proceeds from these notes and the proceeds from asset sales to prepay its 5.5% senior notes due December 2016 in the amount of $300 million, its 6.625% senior notes due October 2017 in the amount of $296.5 million and its 7.5% medium term notes due January 2018 in the amount of $100.0 million. This prepayment resulted in a $27.1 million loss on debt extinguishment.

During the year ended December 31, 2016, the Company purchased an aggregate of 1.4 million common shares for $40.9 million as part of a share repurchase plan.

In October 2017, the Company replaced its existing $800 million credit facility with the new $800 million Facility and a $100 million DDTL.

In October 2017, the Company entered into a working capital line of credit for aggregate borrowings of up to $30 million.

In December 2018, the Company entered into a £129.5 million ten-year mortgage loan secured by properties in the Company's United Kingdom reportable segment at an interest rate of 2.64%.

In January 2019, the Company issued $350 million of 4.375% senior unsecured notes due 2029. The Company used the proceeds to pay down its revolving credit facilities.

In October and November 2018, in anticipation of conducting an offering of senior notes, the Operating Partnership entered into two interest rate lock agreements tied to the U.S. treasury rate. These agreements were settled prior to the consummation of the above-described senior note offering for an aggregate cost to the Operating Partnership of $5.7 million. See Note 20 - Derivative Instruments.

The Company funds its development activities and acquisitions with long-term capital sources and proceeds from the disposition of properties. For the year ended December 31, 2018, a portion of these activities were funded through the Facilities.

The Company uses debt financing to lower its overall cost of capital in an attempt to increase the return to shareholders. The Company staggers its debt maturities and maintains debt levels it considers to be prudent. In determining its debt levels, the Company considers various financial measures including the debt to gross assets ratio and the fixed charge coverage ratio. As of December 31, 2018, the Company’s debt to gross assets ratio was 38.9% and for the year ended December 31, 2018, the fixed charge coverage ratio was 3.5x. Debt to gross assets equals total long-term debt and borrowings under the Facilities divided by total assets plus accumulated depreciation (including accumulated depreciation in assets held for sale). The fixed charge coverage ratio equals net income before property dispositions plus interest expense, depreciation and amortization, share based compensation and impairment - real estate assets (including the Company's pro rata share of impairment - real estate assets related to unconsolidated

Table of Contents

joint ventures), divided by interest expense, including capitalized interest, plus distributions on preferred units. All amounts in the calculation of fixed charge coverage include components within both continuing and discontinued operations.

As of December 31, 2018, $393.8 million of mortgage loans (including $66.8 million fixed via a swap arrangement - see Note 20 to the Company's Consolidated Financial Statements) and $2.3 billion in unsecured notes were outstanding with a weighted average interest rate of 3.90%. The interest rates on $2,693.8 million of mortgage loans and unsecured notes are fixed (including those fixed via swap agreements) and range from 2.6% to 4.8%. The weighted average remaining term for the mortgage loans and unsecured notes as of December 31, 2018 was 5.1 years.

The Company's contractual obligations, as of December 31, 2018, were as follows (in thousands):

(1)	The Company is contractually committed to build a minimum of 60,000 square feet of building space every two years at the Navy Yard Corporate Center in Philadelphia, with certain rights to defer these biennial requirements. The failure by the Company to meet these milestones could result in the loss of the Company’s exclusive development rights with respect to the Navy Yard Corporate Center.


(2)	Includes principal and interest payments. Interest payments assume borrowings under the Facilities and interest rates remain at the December 31, 2018 level until maturity.


(3)	Included in the development commitment is approximately $170.9 million in costs related to the Company's agreement to develop, on a fee basis, an office building and infrastructure improvements for American Water Works in Camden, New Jersey, of which $159.2 million has been incurred. This building was delivered in December 2018.

As discussed above and in Note 7 to the Company's Consolidated Financial Statements, the Company may initially be required to fund cost overruns in connection with its development of the Comcast Technology Center. As of December 31, 2018, the Company accrued $67.1 million relating to such contingency. Such amount is not included in the table above.

General

The Company believes that its existing sources of capital will provide sufficient funds to finance its continued development and acquisition activities. The Company's existing sources of capital include the public debt and equity markets, proceeds from secured financing of properties, proceeds from property dispositions, equity capital from joint venture partners, remaining capacity of $125.0 million under the Company's at-the-market equity offering program and net cash provided by operating activities. Additionally, the Company expects to incur variable rate debt, including borrowings under the Facilities, from time to time.

The Company's annual Common Share dividend paid was $1.60 per share, $1.675 per share and $1.90 per share in 2018, 2017 and 2016, respectively. Future distribution payments by the Company will be paid at the discretion of the Board of Trustees and will depend on the Company's actual funds from operations and cash flows, the Company’s financial condition and capital requirements, the annual distribution requirements under the REIT provisions of the Internal Revenue Code and other factors that the Board of Trustees deems relevant. The Company’s Board of Trustees reviews the dividend quarterly, and there can be no assurance about the amount of future quarterly distribution payments.

The Company has an effective S-3 shelf registration statement on file with the SEC pursuant to which the Trust and the Operating Partnership may issue an unlimited amount of equity securities and debt securities.

Off-Balance Sheet Arrangements

As of December 31, 2018, the Company had investments in and advances to unconsolidated joint ventures totaling $351.0 million (see Note 7 to the Company's Consolidated Financial Statements included in this report).

Calculation of Funds from Operations

The National Association of Real Estate Investment Trusts (“NAREIT”) has issued a standard definition for NAREIT Funds from operations (as defined below). The SEC has agreed to the disclosure of this non-US GAAP financial measure on a per share basis in its Release No. 34-47226, Conditions for Use of Non-US GAAP Financial Measures. The Company believes that the calculation of NAREIT Funds from operations is helpful to investors and management as it is a measure of the Company’s operating performance that excludes depreciation and amortization and gains and losses from operating property dispositions. As a result, year over year comparison of NAREIT Funds from operations reflects the impact on operations from trends in occupancy rates, rental rates, operating costs, development activities, general and administrative expenses, and interest costs, providing perspective not immediately apparent from net income. In addition, management believes that NAREIT Funds from operations provides useful information to the investment community about the Company’s financial performance when compared to other REITs since NAREIT Funds from operations is generally recognized as the standard for reporting the operating performance of a REIT. NAREIT Funds from operations available to common shareholders is defined by NAREIT as net income (computed in accordance with generally accepted accounting principles (“US GAAP”)), excluding gains (or losses) from sales of property and impairment - real estate assets, plus depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. NAREIT Funds from operations available to common shareholders does not represent net income or cash flows from operations as defined by US GAAP and does not necessarily indicate that cash flows will be sufficient to fund cash needs. It should not be considered as an alternative to net income as an indicator of the Company’s operating performance or to cash flows as a measure of liquidity. NAREIT Funds from operations available to common shareholders also does not represent cash flows generated from operating, investing or financing activities as defined by US GAAP.

Inflation

Inflation has remained relatively low in recent years, and as a result, it has not had a significant impact on the Company during this period. To the extent an increase in inflation would result in increased operating costs, such as insurance, real estate taxes and

Table of Contents

utilities, the majority of the tenants’ leases require the tenants to absorb these costs as part of their rental obligations. In addition, inflation also may have the effect of increasing market rental rates.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The following discussion about the Company's risk management includes forward-looking statements that involve risks and uncertainties. Actual results could differ materially from the results discussed in the forward-looking statements.

The carrying value of cash and cash equivalents, restricted cash, accounts receivable, accounts payable, accrued interest, dividends and distributions payable and other liabilities are reasonable estimates of fair value because of the short-term nature of these instruments. The fair value of the Company's long-term debt, which is based on estimates by management and on rates quoted on December 31, 2018 for comparable loans, is greater than the aggregate carrying value by approximately $12.0 million at December 31, 2018.

The Company's primary market risk exposure is to changes in interest rates. The Company is exposed to market risk related to its Credit Facility and certain other indebtedness as discussed in "Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources."

The Company also uses long-term and medium-term debt as a source of capital. These debt instruments are typically issued at fixed interest rates. When these debt instruments mature, the Company typically refinances such debt at then-existing market interest rates which may be more or less than the interest rates on the maturing debt. In addition, the Company may attempt to reduce interest rate risk associated with an issuance of new debt. Our interest rate risk objective is to limit the impact of interest rate changes on earnings and cash flows and lower our overall borrowing costs. To achieve these objectives, from time to time the Company enters into interest rate hedge contracts such as collars, swaps, caps and treasury lock agreements in order to mitigate our interest rate risk with respect to various debt instruments. The Company does not hold or issue these derivative contracts for trading or speculative purposes.

If the interest rates for variable rate debt were 100 basis points higher or lower during 2018, the Company's interest expense would have increased or decreased by $3.2 million. If the interest rate for the fixed rate debt maturing in 2019 had been 100 basis points higher or lower than its current rate of 3.9%, the Company's interest expense would have increased or decreased by $407,000.

The sensitivity analysis above assumes no changes in the Company's financial structure. It also does not consider future fluctuations in interest rates or the specific actions that might be taken by management to mitigate the impact of such fluctuations.

We are exposed to foreign currency exchange variability related to investments in and earnings from our investments in the United Kingdom. Foreign currency market risk is the possibility that our results of operations or financial position could be better or worse than anticipated because of changes in foreign currency exchange rates. We primarily hedge our foreign currency risk by borrowing in the currency in which we invest, thereby providing a natural hedge. As of December 31, 2018, we had outstanding debt denominated in British pounds sterling of £129.5 million (approximately $165.2 million), which was secured by U.K. real estate assets. As of December 31, 2018 we did not have any foreign currency hedges in place.

Management's Annual Report on Internal Control Over Financial Reporting

The Trust's management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a - 15 (f) and 15d - 15(f). The Trust's internal control system was designed to provide reasonable assurance to the Trust's management and Board of Trustees regarding the preparation and fair presentation of published financial statements.

Under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer, we assessed the effectiveness of the Trust's internal control over financial reporting as of December 31, 2018. In making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control - Integrated Framework (2013 Framework). Based on our assessment we believe that, as of December 31, 2018, the Trust's internal control over financial reporting is effective based on those criteria.

The Trust's independent registered public accounting firm, Ernst & Young LLP, has issued an attestation report on the Trust's internal control over financial reporting, which is included in this Annual Report on Form 10-K.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

We have audited the accompanying consolidated balance sheets of Liberty Property Limited Partnership (the “Operating Partnership”) as of December 31, 2018 and 2017, the related consolidated statements of comprehensive income, owners’ equity and cash flows for each of the three years in the period ended December 31, 2018, and the related notes and schedules listed in the Index at Item 15 (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Operating Partnership at December 31, 2018 and 2017, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2018, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Operating Partnership’s internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 26, 2019 expressed an unqualified opinion thereon.

Adoption of New Accounting Standard

As discussed in Note 2 to the consolidated financial statements, the Operating Partnership changed its method of accounting for determining whether an acquisition is an asset or a business effective October 1, 2016 due to the early adoption of Accounting Standards Update No. 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business”.

Basis for Opinion

These financial statements are the responsibility of the Operating Partnership’s management. Our responsibility is to express an opinion on the Operating Partnership’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Operating Partnership in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

/s/ Ernst & Young LLP

We have served as the Operating Partnership’s auditor since 1993.

Liberty Property Trust and Liberty Property Limited Partnership

Notes to Consolidated Financial Statements

December 31, 2018

1. ORGANIZATION

Liberty Property Trust (the “Trust”) is a self-administered and self-managed Maryland real estate investment trust (a “REIT”). Substantially all of the Trust’s assets are owned directly or indirectly, and substantially all of the Trust’s operations are conducted directly or indirectly, by its subsidiary, Liberty Property Limited Partnership, a Pennsylvania limited partnership (the “Operating Partnership” and, together with the Trust and their consolidated subsidiaries, the “Company”). The Trust is the sole general partner and also a limited partner of the Operating Partnership, owning 97.7% of the common equity of the Operating Partnership at December 31, 2018. The Company owns and operates industrial properties in the United States nationally, as well as in the United Kingdom. The Company intends to divest its remaining office properties (other than its headquarters) over the next few years and focus its efforts and capital solely on its industrial platform. Unless otherwise indicated, the notes to the Consolidated Financial Statements apply to both the Trust and the Operating Partnership. The terms the "Company,” “we,” “our” and “us” means the Trust and Operating Partnership collectively.

The Operating Partnership is a variable interest entity ("VIE") of the Trust as the limited partners do not have substantive kick-out or participating rights. The Trust is the primary beneficiary of the Operating Partnership as it has the power to direct the activities of the Operating Partnership and the rights to absorb 97.7% of the net income of the Operating Partnership. The Trust has no significant assets or liabilities other than its investment in the Operating Partnership. As the Operating Partnership is already consolidated in the balance sheets of the Trust, the identification of this entity as a VIE has no impact on the consolidated financial statements of the Trust. In addition, the Company holds a 20% interest in Liberty/Comcast 1701 JFK Boulevard, LP which was determined to be a VIE. The Company determined that it is not the primary beneficiary as the Company and its third-party partner share control of the joint venture. The Company's maximum exposure to loss is equal to its equity investment in the joint venture which was $75.1 million and $17.3 million as of December 31, 2018 and 2017, respectively.

All square footage amounts are unaudited.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles ("US GAAP") requires management to make estimates and assumptions that affect amounts reported in the financial statements and accompanying notes.

Actual results could differ from those estimates.

Principles of Consolidation

The consolidated financial statements of the Company include the Trust, the Operating Partnership, wholly owned subsidiaries and those subsidiaries in which the Company owns a majority voting interest with the ability to control operations of the subsidiaries and where no approval, veto or other important rights have been granted to the noncontrolling shareholders. The Company consolidates joint ventures that are considered to be variable interest entities (“VIEs”) where we are the primary beneficiary. The Company (i) evaluates the sufficiency of the total equity investment at risk, (ii) reviews the voting rights and decision-making authority of the equity investment holders as a group and whether there are any guaranteed returns, protection against losses, or capping of residual returns within the group and (iii) establishes whether activities within the venture are on behalf of an investor with disproportionately few voting rights in making this VIE determination. To the extent that the Company (i) is the sole entity that has the power to direct the activities of the VIE and (ii) has the obligation or rights to absorb the VIE's losses or receive its benefits, then the Company would be the primary beneficiary and would consolidate the VIE.

All significant intercompany transactions and accounts have been eliminated.

Reclassifications

Certain amounts from prior years have been reclassified to conform to current-year presentation including reclassifying the accompanying consolidated balance sheets for assets held for sale and the consolidated statements of comprehensive income for discontinued operations.

In 2018, the Company began to separately classify other operating expenses in the Consolidated Statements of Comprehensive Income. Other operating expenses include expensed pursuit costs, system implementation costs and severance costs.

Table of Contents

The Company is incurring costs associated with its efforts to implement new financial and operating systems in certain cloud computing arrangements. The Company evaluated the arrangements in accordance with ASU 2015-05 "Customer's Accounting for Fees Paid in a Cloud Computing Arrangement" and concluded that such arrangements are service contracts under the standard. Accordingly, the Company expenses substantially all costs as incurred. Certain costs that relate to the software service agreements received over time are set up as prepaid and expensed over the applicable service period. These costs include license costs during the implementation period as well as consulting, personnel and other direct costs related to the implementation.

The Company capitalizes pre-development costs incurred in pursuit of new development opportunities for which the Company currently believes future development is probable. Future development is dependent upon various factors, including zoning and regulatory approval, rental market conditions and construction costs. Initial pre-development costs incurred for pursuits for which future development is not yet considered probable are expensed as incurred. In addition, if the status of a future development by the Company is no longer probable, any capitalized pre-development costs are written off with a charge to expense.

Severance costs are incurred in conjunction with certain headcount reductions relating primarily to the Company's change in strategy.

Previously, expensed pursuit costs were on a separate line item on the Company's Consolidated Statements of Comprehensive Income in amounts per the table below. Systems implementation costs and severance costs were included in general and administrative expense in amounts as follows (in thousands):



	2017		2016
Expensed pursuit costs	$	5,066	$	1,016
General and administrative expense	1,011		4,001

Concentration of Credit Risk

As of December 31, 2018, wholly owned properties were leased to 1,084 customers. The geographic locations that comprise greater than 10% of our segment level operating revenues were Lehigh Valley/Central PA and Carolinas/Richmond. Our customers engage in a wide variety of businesses. No single customer generated more than 4.3% of our consolidated operating rental revenues during 2018. In 2018, the Sears Holdings Corporation filed for reorganization under Chapter 11 of the federal bankruptcy laws. This tenant represents 0.8% of consolidated operating rental revenues during 2018.

Real Estate and Depreciation

The properties are recorded at cost and are depreciated using the straight line method over their estimated useful lives. The estimated useful lives are as follows:



Building and improvements		40 years (blended)
Capital improvements		15 - 20 years
Equipment		5 - 10 years
Tenant improvements		Term of the related lease

The Company capitalizes costs associated with development and redevelopment activities, capital improvements, tenant improvements and leasing activities, including compensation costs. Expenditures directly related to the improvement of real estate, including interest and other costs capitalized on development and redevelopment projects and land being readied for development, are included in net real estate and are stated at cost. The Company considers a development property substantially complete upon the completion of tenant build-out, but no later than one year after the completion of major construction activity. These capitalized costs include pre-construction costs essential to the development of the property, construction costs, interest costs, real estate taxes, development related compensation and other costs incurred during the period of development. The determination to capitalize rather than expense costs requires the Company to evaluate the status of the development activity. The total of capitalized compensation costs directly related to development, redevelopment, capital improvements, and tenant improvements for the years ended December 31, 2018, 2017 and 2016 was $7.1 million, $5.5 million and $7.2 million, respectively. Construction related payables at December 31, 2018 and 2017 were $48.1 million and $49.3 million, respectively.

The Company allocates the purchase price of real estate acquired to land, building and improvements and intangibles based on the relative fair value of each component. Lease values for acquired properties are determined based on the present value (using a discount rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to each in-place lease and (ii) management's estimate of fair market lease rates for each corresponding in-place

Table of Contents

lease ("Market Value Intangible"). Origination values are also assigned to in-place leases, and, where appropriate, value is assigned to customer relationships ("Origination Value Intangible").

Acquisition-related costs for asset acquisitions are capitalized and included in net real estate at cost. Expenditures for maintenance and repairs are charged to operations as incurred.

The Company depreciates the amounts allocated to building and improvements over 40 years and amortizes the amounts allocated to intangibles relating to in-place leases, which are included in deferred financing and leasing costs and other liabilities in the accompanying consolidated balance sheets, over the remaining term of the related leases. Market Value Intangible amortization is recorded as rental revenue. Origination Value Intangible amortization is recorded as depreciation and amortization. This calculation includes both the remaining noncancelable period and any bargain renewal option periods.

Once a property is designated as held for sale, no further depreciation expense is recorded.

The Company evaluates its real estate investments upon occurrence of a significant adverse change in its operations and/or market price, an expectation that the asset will be sold or otherwise disposed of before the end of its estimated useful life, among other factors, to assess whether any impairment indicators are present that affect the recovery of the recorded value. If indicators of impairment are identified, the Company estimates the future undiscounted cash flows from the use and eventual disposition of the property and compares this amount to the carrying value of the property. If any real estate investment is considered impaired, a loss is recognized to reduce the carrying value of the property to its estimated fair value. If held for sale, a property is not considered impaired unless its estimated fair value (less costs to sell) is less than the property's book value at the balance sheet date.

Investments in Unconsolidated Joint Ventures

The Company accounts for its investments in unconsolidated joint ventures using the equity method of accounting as the Company exercises significant influence, but does not control these entities.

Under the equity method of accounting, the net equity investment of the Company is reflected in the accompanying consolidated balance sheets and the Company's share of net income from the joint ventures is included in the accompanying consolidated statements of comprehensive income.

On a periodic basis, management assesses whether there are any indicators that the value of the Company's investments in unconsolidated joint ventures may be other-than-temporarily-impaired. An investment is impaired only if management's estimate of the value of the investment is less than the carrying value of the investment, and such decline in value is deemed to be other-than-temporary. To the extent impairment has occurred, the loss is measured as the excess of the carrying amount of the investment over the estimated fair value of the investment. The estimated fair value of the investments is determined using a discounted cash flow model which is a Level 3 valuation under ASC 820, "Fair Value Measurement." The Company considers a number of assumptions that are subject to economic and market uncertainties including, among others, demand for space, competition for tenants, changes in market rental rates, operating costs, capitalization rates, holding periods and discount rates.

No other-than-temporary impairment losses on the Company's investments in unconsolidated joint ventures were recognized during the years ended December 31, 2016, 2017 or 2018.

Cash and Cash Equivalents

Highly liquid investments with a maturity of three months or less when purchased are classified as cash equivalents.

Restricted Cash

Restricted cash includes tenant security deposits and escrow funds that the Company maintains pursuant to certain mortgage loans. Restricted cash also includes the undistributed proceeds from the sale of residential land in Kent County, United Kingdom.

Table of Contents

Accounts Receivable/Deferred Rent Receivable

The Company's accounts receivable are comprised of rents and charges for property operating costs due from tenants. The Company's deferred rent receivable represents the cumulative difference between rent revenue recognized on a straight line basis and contractual payments due under the terms of tenant leases. The Company periodically performs a detailed review of amounts due from tenants to determine if accounts receivable and deferred rent receivable balances are collectible. Based on this review, accounts receivable and deferred rent receivable are reduced by an allowance for doubtful accounts. The Company considers tenant credit quality and payment history and general economic conditions in determining the allowance for doubtful accounts. If the accounts receivable balance or the deferred rent receivable balance is subsequently deemed uncollectible, the receivable and allowance for doubtful account balance are written off.

The allowance for doubtful accounts at December 31, 2018 and 2017 was $6.4 million and $6.6 million, respectively. The Company recognized bad debt expense of $1.4 million, $0.6 million and $0.6 million for the years ended December 31, 2018, 2017 and 2016, respectively.

Revenue Recognition

The Company earns rental income under operating leases with tenants. Rental income is recognized on a straight line basis over the applicable non-cancelable lease term. Operating expense reimbursements consisting of amounts due from tenants for real estate taxes, utilities and other recoverable costs are recognized as revenue in the period in which the corresponding expenses are incurred.

The Company considers any renewal options in determining the lease term. To the extent a lease includes a tenant option to renew or extend the duration of the lease at a fixed or determinable rental rate, the Company evaluates whether or not that option represents a bargain renewal option by analyzing if there is reasonable assurance at lease inception that the tenant will exercise the option because the rental rate is sufficiently lower than the expected rental rate for equivalent property under similar terms and conditions at the exercise date.

Termination fees (included in rental revenue) are fees that the Company has agreed to accept in consideration for permitting certain tenants to terminate their lease prior to the contractual expiration date. The Company recognizes termination fees during the period that landlord services are rendered in accordance with Securities and Exchange Commission Staff Accounting Bulletin 104, "Revenue Recognition," after the following conditions are met:


a.	the termination agreement is executed,


b.	the termination fee is determinable, and


c.	collectability of the termination fee is assured.

Effective January 1, 2018, the Company adopted the "New Revenue Standards," comprised of: ASU 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), which supersedes nearly all existing revenue recognition guidance (except revenue in the scope of other accounting standards, including standards related to leasing) as well as the following standards subsequently issued by the FASB related to ASU 2014-09: ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations; ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing; ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients; ASU 2017-05, Gains and Losses from the Derecognition of Nonfinancial Assets (Topic 610-20), and ASU 2017-13, Revenue from Contracts with Customers (Topic 606): Amendments to SEC Paragraphs Pursuant to the Staff Announcement at the July 20, 2017 EITF Meeting and Rescission of Prior SEC Staff Announcements and Observer Comments.

The New Revenue Standards provide a unified model to determine how revenue is recognized. In accordance with the New Revenue Standards, the Company performs the following steps: (i) identify the contract with the customer, (ii) identify the performance obligations within the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations and (v) recognize revenue when (or as) a performance obligation is satisfied. The Company evaluated each of its revenue streams: lease agreement revenue, development service fee revenue, deferred land sale revenue and gain or loss on sale of nonfinancial assets and adopted the New Revenue Standards effective January 1, 2018 using the modified retrospective approach. The Company concluded that there are no revenue streams from its lease agreements that are covered by the New Revenue Standards. The Company adopted the practical expedient to assess the recognition of revenue for open contracts during the transition period. There was no adjustment to the opening balance of retained earnings recorded at January 1, 2018.

Table of Contents

In the fourth quarter of 2016, the Company entered into an agreement relating to the fee development of an office building at its Camden Waterfront project in Camden, NJ. Project revenues and related costs and expenses are presented on a gross basis as "Development service fee income" and "Development service fee expense" in the Consolidated Statements of Comprehensive Income. Additionally, at the same time, the Company began classifying development fees and expenses relating to its fee development arrangements for certain unconsolidated joint venture projects in a manner consistent with the Camden project described above. Previously, development service fee income relating to its unconsolidated joint ventures had been classified as other income and development service fee expense had been classified as general and administrative expense in amounts as follows:



	Nine months ended
	September 30, 2016
	(unaudited)
Other income	$	3,789
General and administrative expense	$	3,210

For the years ended December 31, 2017 and 2016, revenue and expense associated with service fee development was accounted for under the percentage of completion method. Revenues were recognized on the percentage of completion method based on applicable costs incurred with respect to each development agreement. The Company used the relative sales value method to allocate costs and recognize profits from service fee development. Under the relative sales value method, estimates of aggregate project revenues and aggregate project costs are used to determine the allocation of project cost of sales and the resulting profit in each accounting period. In subsequent periods, cost of sale allocations and the resulting profits are adjusted to reflect changes in the actual and estimated costs and revenues of each project. Provisions for estimated losses on uncompleted contracts are recognized immediately in the period in which such losses are determined.

The New Revenue Standards did not have an impact on the amount and timing of recognizing the Company's development service fee income. The Company recognizes development service fee income on a variable basis as a percentage of costs incurred on third party development contracts. Property development services, which are a single performance obligation, continue to be satisfied and recognized over time. The Company measures its progress toward completing the performance obligation under each

The Company receives cash as it sells improved land sites on behalf of its development partner to home builders in the United Kingdom. These agreements contain a pre-emption clause and a seller's call option. The Company recognizes revenue as the pre-emption period or seller's call option lapses utilizing the output method. There was $2.4 million, $0.3 million, and $2.6 million in revenue recognized for such contracts during the years ended December 31, 2018, 2017 and 2016, respectively.

The New Revenue Standards did not have an impact on the gain or loss on sale of nonfinancial assets. The New Revenue Standards

require the Company to derecognize nonfinancial assets once it transfers control of a distinct nonfinancial asset or distinct in substance nonfinancial asset. Additionally, when the Company transfers its controlling interest in a nonfinancial asset, but retains

a noncontrolling ownership interest, the Company is required to measure any noncontrolling interest it receives or retains at fair

value. The guidance requires companies to recognize a full gain or loss on the transaction. See Note 6 - Real Estate, Note 7 - Investments in Unconsolidated Joint Ventures and Note 19 - Accounting for the Impairment or Disposal of Long-lived Assets for further discussion of sales of nonfinancial assets.

Estimated gross revenue related to the remaining performance obligations under existing contracts (before allocation of related costs and expenses) as of December 31, 2018 that will be recognized as revenue in future periods was approximately $37.1 million,

which is expected to be recognized through 2021.

Deferred Financing and Leasing Costs

Costs incurred in connection with leasing or financing of the credit facilities are capitalized and amortized on a straight line basis over the term of the related lease or loan. Costs incurred in connection with the financing of mortgage loans or unsecured notes are reported as a deduction from the face amount of that liability and amortized on a straight line basis over the term of the related loan. Deferred financing cost amortization is reported as interest expense.

Table of Contents

Certain employees of the Company are compensated for leasing services related to the Company's properties. The compensation directly related to these leasing services is capitalized and amortized as a deferred leasing cost over the term of the related lease. The total of this capitalized compensation was $2.7 million, $3.6 million and $3.8 million for the years ended December 31, 2018, 2017 and 2016, respectively. Effective January 1, 2019, as a result of the New Lease Standard, only incremental, direct costs will be capitalizable and therefore, certain compensation costs for leasing services will be expensed as incurred.

Fair Value of Financial Instruments

ASC 820, Fair Value Measurements and Disclosures, gives guidance on the fair value measurement of a financial asset or liability. Inputs used to develop fair value are classified in one of three categories: Level 1 inputs (quoted prices (unadjusted) in active markets for identical assets or liabilities), Level 2 inputs (inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly) and Level 3 inputs (unobservable inputs for the asset or liability).

The following disclosure of estimated fair value was determined by management using available market information and appropriate valuation methodologies. However, considerable judgment is necessary to interpret market data and develop estimated fair value. Accordingly, the following estimates are not necessarily indicative of the amounts the Company could have realized on disposition of the financial instruments at December 31, 2018 and December 31, 2017. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.

The carrying value of cash and cash equivalents, restricted cash, accounts receivable, accounts payable, accrued interest, dividend and distributions payable and other liabilities are reasonable estimates of fair value because of the short-term nature of these instruments. The carrying value of the outstanding amounts under the Company's credit facilities is also a reasonable estimate of fair value because interest rates float at a rate based on LIBOR.

The Company determines the fair value of its interest rate swaps by using the standard methodology of netting discounted future fixed cash payments with the discounted expected variable cash receipts. These variable cash receipts of interest rate swaps are based on expectations of future LIBOR interest rates (forward curves) estimated by observing market LIBOR interest rate curves. This is a Level 2 fair value calculation. Also, credit valuation adjustments are factored into the fair value calculations to account for potential nonperformance risk. These credit valuation adjustments were concluded to be not significant inputs for the fair value calculations for the periods presented. See Note 20 - Derivative Instruments.

The Company used a discounted cash flow model to determine the estimated fair value of its debt as of December 31, 2018 and December 31, 2017. This is a Level 3 fair value calculation. The inputs used in preparing the discounted cash flow model include actual maturity dates and scheduled cash flows as well as estimates for market value discount rates. The Company updates the discounted cash flow model on a quarterly basis to reflect any changes in the Company's debt holdings and changes to discount rate assumptions.

The following summarizes the fair value of the Company's mortgage loans and unsecured notes at December 31, 2018 and December 31, 2017 (in thousands):



	Mortgage Loans				Unsecured Notes

Income Taxes

The Company has elected to be taxed as a REIT under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the "Code"). As a result, the Company generally is not subject to federal income taxation at the corporate level to the extent it distributes annually at least 100% of its REIT taxable income, as defined in the Code, to its shareholders and satisfies certain other organizational and operational requirements. The Company has met these requirements and, accordingly, no provision has been made for federal income taxes in the accompanying consolidated financial statements. If the Company fails to qualify as a REIT in any taxable year, the Company will be subject to federal income tax on its taxable income at regular corporate rates (including any alternative minimum tax for those tax years beginning prior to January 1, 2018) and may not be able to qualify as a REIT for the four subsequent taxable years. Even as a REIT, the Company may still be subject to certain state and local income and property taxes, and to federal income and excise taxes on undistributed taxable income. The Company continues to consider and implement the relevant provisions of the Tax Cuts and Jobs Act (the "TCJA"), which was signed into law on December 22, 2017 and which generally took effect for taxable years beginning on or after January 1, 2018. Based upon its assessment, when combined with the guidance issued to date by both the Internal Revenue Service and the United States Treasury Department, the Company does not reasonably believe or expect those provisions, or the TCJA in general, will have a material impact on its overall financial condition, business operations or ability to continue to qualify as a REIT on a going forward basis.

Several of the Company's subsidiaries are taxable REIT subsidiaries (each a "TRS") and are subject to federal and state income taxes separate from the Company. In general, a TRS may perform additional services for tenants and generally may engage in real estate or non-real estate businesses that are not permitted REIT activities. The Company itself is also subject to tax in certain states and the United Kingdom. Accordingly, the Company recognizes federal, state and foreign income taxes in accordance with US GAAP, as applicable. In addition, the TCJA implemented a one-time deemed repatriation tax on offshore corporate profits, including any such profits which the Company may have accumulated over the years in its offshore TRSs, at the reduced rates of 15.5% on cash assets and 8% on noncash assets. The Company has reviewed its accumulated offshore earnings through December 31, 2017 and this provision of the TCJA did not have a material impact on the Company’s overall financial condition or results of operation or its 2017 federal and state tax return filings.

Currently there are no uncertain tax positions or possibly significant unrecognized tax benefits that are reasonably expected to occur within the next 12 months. The Company's policy is to recognize interest accrued related to unrecognized benefits in interest expense and penalties in other expense. There were no interest or penalties deducted in any of the years ended December 31, 2018, 2017 and 2016 and no interest and penalties accrued at December 31, 2018 or December 31, 2017 which related to any uncertain tax positions or significant unrecognized tax benefits.

As of December 31, 2018, certain of the Company's TRSs have estimated net operating loss ("NOL") carryforwards available of approximately $20.8 million. Unless reduced or utilized, these NOL carryforwards are set to begin expiring in 2020. Additionally, the TCJA reduced the corporate federal tax rate in the U.S. from 35% to 21% effective for tax years beginning after December 31, 2017 while also reducing the amount of newly generated NOLs that can generally be utilized by a taxpayer in any tax year from 100% of net taxable income to 90%. As such, deferred tax assets and liabilities, where applicable, were remeasured to account for these changes. After taking into consideration the projected future net taxable income at these entities, and consistent with prior periods, the Company has determined that a valuation allowance for the full carrying value of NOL carryforwards is appropriate.

The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction, certain state and local jurisdictions, the United Kingdom and (in prior years) Luxembourg. With few exceptions, the Company and its subsidiaries are no longer subject to examination by taxing authorities in these jurisdictions for years prior to 2012.

The Federal tax cost basis of the wholly owned real estate was $7.1 billion and $6.8 billion at December 31, 2018 and 2017, respectively.

Share-Based Compensation

Share-based compensation cost is measured at the grant date, based on the fair value of the award, and is recognized as expense over the employees' requisite service period. The Company recognizes forfeitures on share based compensation as they occur.

Derivative Financial Instruments

The Company borrows funds at a combination of fixed and variable rates. Borrowings under our Facilities and certain bank mortgage loans bear interest at variable rates. Our long-term debt typically bears interest at fixed rates. Our interest rate risk management objectives are to limit generally the impact of interest rate changes on earnings and cash flows and to lower our overall borrowing costs. To achieve these objectives, from time to time, we enter into interest rate hedge contracts such as collars, swaps, caps and treasury lock agreements in order to mitigate our interest rate risk with respect to various debt instruments. We

Table of Contents

generally do not hold or issue these derivative contracts for trading or speculative purposes. The interest rate on all of our variable rate debt is generally adjusted at one or three month intervals, subject to settlements under interest rate hedge contracts.

Interest rate swaps involve the receipt of variable-rate amounts from a counterparty in exchange for making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive loss (for the Trust) and general partner's equity and limited partners' equity - common units (for the Operating Partnership) and is subsequently reclassified into interest expense in the period that the hedged forecasted transaction affects earnings.

Foreign Currency

The functional currency of the Company's United Kingdom operations is pounds sterling. The Company translates the financial statements for the United Kingdom operations into US dollars. For the Trust, gains and losses resulting from this translation are included in accumulated other comprehensive loss as a separate component of shareholders' equity and a proportionate amount of gain or loss is allocated to noncontrolling interest - operating partnership - common units. For the Operating Partnership, gains and losses resulting from this translation are included in general partner's equity and limited partners' equity - common units. Upon sale or upon complete or substantially complete liquidation of the Company's foreign investment, the gain or loss on the sale will include the cumulative translation adjustments that have been previously recorded in accumulated other comprehensive loss and noncontrolling interest - operating partnership - common units (for the Trust) and in general partner's equity and limited partners' equity - common units (for the Operating Partnership).

Comprehensive Income

Comprehensive income, as reflected on the consolidated statements of comprehensive income, is defined as all changes in equity during each period except for those resulting from investments by or distributions to shareholders. Accumulated other comprehensive loss, as reflected on the Company's consolidated balance sheets and consolidated statements of equity, reflects the effective portion of the cumulative changes in the fair value of derivatives in qualifying cash flow hedge relationships as well as gains and losses resulting from foreign currency translation.

Earnings Per Share of the REIT

Basic earnings per share is calculated by dividing the income available to common shareholders for the period by the weighted average number of common shares outstanding during the period using the two class method. Diluted earnings per share is calculated by dividing the net income available to common shareholders for the period by the weighted average number of common and dilutive securities outstanding during the period.

Earnings Per Unit of the Operating Partnership

Basic earnings per unit is calculated by dividing the income available to common unitholders for the period by the weighted average number of common units outstanding during the period using the two class method. Diluted earnings per unit is calculated by dividing the income available to common unitholders for the period by the weighted average number of common and dilutive securities outstanding during the period.

Recently Issued Accounting Standards

Leases

In February 2016, the FASB issued ASU 2016-02, Leases (“ASU 2016-02”). Subsequently the FASB issued the following standards related to ASU 2016-02: ASU 2018-10, Codification Improvements to Topic 842, Leases and ASU 2018-11, Leases (Topic 842): Targeted Improvements (collectively, the "New Lease Standard"). The New Lease Standard amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making targeted changes to lessor accounting.

The New Lease Standard requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. In addition, the New Lease Standard limits the capitalization of costs by lessors to incremental direct leasing costs. Therefore the Company will no longer capitalize and amortize certain leasing related costs and instead will expense these costs as incurred. Such capitalized costs were approximately $1 million for the year ended December 31, 2018.

The New Lease Standard provides lessors a practical expedient to not separate lease and non-lease components if certain criteria are met. The Company assessed these criteria and concluded that the timing and pattern of transfer for non-lease components and

Table of Contents

lease components are the same, and therefore will account for and present rental revenue and operating expense reimbursements as a single component.

The Company is a lessee of ground and office space leases. In accordance with the New Lease Standard, for lease agreements longer than one year, the Company will measure the present value of the future lease payments and recognize a right-of-use asset and corresponding lease liability on its balance sheet estimated to range from $18 million to $20 million.

The Company adopted the New Lease standard on January 1, 2019 and applied it prospectively. The following practical expedients available for implementation were elected:


a.	whether an expired or existing contract meets the definition of a lease


b.	the lease classification at the adoption date for existing or expired leases


c.	whether costs previously capitalized as initial direct costs would continue to be amortized

The Company therefore does not expect an adjustment to the opening balance of retained earnings.

Other

In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). ASU 2016-15 is designed to clarify how entities should classify cash receipts and cash payments in the statement of cash flows. ASU 2016-15 became effective for the Company beginning January 1, 2018. The standard requires retrospective application. The adoption of ASU 2016-15 did not have a material impact on the Company's consolidated financial statements.

In February 2017, the FASB issued ASU 2017-05, Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets ("ASU 2017-05"). ASU 2017-05 is designed to provide guidance on how to recognize gain and losses on sales, including partial sale, of nonfinancial assets to noncustomers. The Company adopted ASU 2017-05 effective January 1, 2018 on a modified retrospective method and the adoption did not have an effect on the Company’s consolidated financial statements.

In May 2017, the FASB issued ASU 2017-09, Scope of Modification Accounting ("ASU 2017-09"). ASU 2017-09 clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. ASU 2017-09 became effective for the Company beginning January 1, 2018. The new guidance was applied prospectively to awards modified on or after the adoption date. The adoption of ASU 2017-09 did not have a material impact on the consolidated financial statements.

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities ("ASU 2017-12"). ASU 2017-12 is designed to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. ASU 2017-12 is effective for the Company beginning January 1, 2019. Early adoption is permitted using a modified retrospective transition method. This adoption method will require the Company to recognize the cumulative effect of initially applying ASU 2017-12 as an adjustment to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings as of the beginning of the fiscal year that an entity adopts the update. The Company does not believe the adoption of the ASU 2017-12 will have a material impact on the consolidated financial statements.

In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software: Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract ("ASU 2018-15"). ASU 2018-15 amends the definition of a hosting arrangement and requires a customer in a hosting arrangement that is a service contract to capitalize certain implementation costs as if the arrangement was an internal-use software project. ASU 2018-15 is effective for the Company beginning January 1, 2020. Upon adoption, the Company does not anticipate the impact of ASU 2018-15 will have a material impact on the consolidated financial statements.

In August 2018, the Securities and Exchange Commission adopted a final rule that eliminated or amended disclosure requirements that were redundant or outdated in light of changes in its requirements, GAAP, or changes in the business environment. The commission also referred certain disclosure requirements to the FASB for potential incorporation into GAAP. The rule is effective for filings after November 5, 2018. The Company assessed the impact of this rule and determined that the changes resulted in clarification or expansion of existing requirements. The Company adopted the rule and it did not have a material impact on the Company’s consolidated financial statements.

Liberty Property 18th & Arch LP and Liberty Property 18th & Arch Hotel, LP

On June 30, 2014, the Company entered into two joint ventures for the purpose of developing and owning the Comcast Technology Center (the "Project") located in Philadelphia, Pennsylvania as part of a mixed-use development. The 60-story building includes 1.3 million square feet of leasable office space (the "Office"), which is substantially complete, and will include a 217-room Four Seasons Hotel (the "Hotel") (collectively, "Liberty Property 18th & Arch"). Project costs for the development of the Project, exclusive of tenant-funded interior improvements, are anticipated to be approximately $961.2 million. The Company's investment in the project is expected to be approximately $192.2 million with 20% ownership interests in both joint ventures. As of December 31, 2018, the Company's investment in these joint ventures was $191.4 million and is reflected in investments in and advances to unconsolidated joint ventures in the Company's consolidated balance sheet. These joint ventures are part of the Company's Philadelphia reportable segment.

The two joint ventures have engaged the Company as the developer of the Project pursuant to a Development Agreement by which the Company agrees, in consideration for a development fee, to be responsible for all aspects of the development of the Project and to guarantee the timely lien-free completion of construction of the Project as well as the payment, subject to certain exceptions, of any cost overruns incurred in the development of the Project. To mitigate its risk, the Company entered into guaranteed maximum price contracts with a third party contractor (the "GMP Contracts") to construct the Project. The Company has been notified by its third-party contractor that the contractor has incurred cost overruns and expects to incur additional construction costs in connection with completing the Project in excess of the guaranteed maximum price payable to the contractor under the GMP Contracts, which guaranteed maximum price has been previously adjusted pursuant to accepted change orders. The Company intends to pursue all remedies to recover from the third-party contractor any amounts expended by the Company or the joint ventures in excess of their contractual obligations. However, the general contractor has generally refused to fund the additional costs, and the Company has begun to fund, and may continue to fund, cost overruns in compliance with its obligations under its development cost guarantee to the joint ventures. The Company has accrued such amounts as additional development service fee expense in its consolidated statements of comprehensive income for year ended December 31, 2018. As of December 31, 2018 and December 31, 2017, the Company had accrued $67.1 million and $5.6 million, respectively, relating to the above-described development cost guarantees which are included in other liabilities in the accompanying consolidated balance sheets. The Company is accounting for the development of the Project using the percentage of completion method. The Company recognized losses of $61.8 million and $3.5 million for the year ended December 31, 2018 and 2017, respectively, and income of $0.6 million for the year ended December 31, 2016 in developer service fee income, net of developer service fee expense and other related expenses.

In addition to the costs to comply with the Company's obligations under its development cost guarantee, claims have been asserted by the third-party contractor and certain subcontractors. There can be no assurances that amounts incurred, including as a result of such claims, will not exceed the above estimates. The Company is not able to reasonably estimate the amount of additional expenses, if any, that it may incur as a result of such claims, and accordingly any potential exposure of the Company for such claims is not included within the accrual described above. If the Company were to incur additional expenses in connection with its development cost guarantee or in connection with such claims, such amounts would be accrued when they are determined to be probable of being incurred and are reasonably estimable, and could be material to the Company’s results of operations in future

periods. If the Company were to subsequently recover any of the cost overruns initially funded by the Company, such recoveries would be recorded when and if realized in future periods.

(1)

Differences between the Company's net investment in unconsolidated joint ventures and its underlying equity in the net assets of the venture are primarily a result of impairments related to the Company's investment in unconsolidated joint ventures, the deferral of gains associated with the sales of properties to joint ventures in which the Company retains an ownership interest and loans made to the joint ventures by the Company. These adjustments have resulted in an aggregate difference reducing the Company's investments in unconsolidated joint ventures by $65.4 million and $3.0 million as of December 31, 2018 and 2017, respectively. Differences between historical cost basis and the basis reflected at the joint venture level (other than loans) are typically depreciated over the life of the related asset.

Credit Facilities

The Company has maintained an unsecured credit facility throughout 2016, 2017 and 2018. During that period the Company has replaced, restated and amended its credit facility. This activity has resulted in changes to borrowing capacity, due dates, borrowing costs and covenant calculations. As replaced, restated and amended these credit facilities are referred to below as the "Credit Facility." The Credit Facility includes a revolving credit facility for aggregate borrowings of $800 million and a delayed draw term loan facility for aggregate borrowings of $100 million. The interest rate on borrowings under the Credit Facility fluctuates based upon ratings from Moody’s Investors Service, Inc., Standard and Poor’s Ratings Group and Fitch, Inc. Based on the Company's ratings as of December 31, 2018, borrowings under the revolving credit facility currently bear interest at LIBOR plus 0.875% and the delayed draw term loan facility bear interest at LIBOR plus 0.95%. The revolving credit facility also contains an annual facility fee, the rate of which is currently 0.15% of the aggregate loan commitments. The Credit Facility provides for the interest rate and facility fee rate to be adjusted up or down based on changes in the credit ratings on the Company's senior unsecured debt. The Credit Facility expires in October 2021 and has two six-month extensions at the Company's option, subject to the payment of a stated fee. The Credit Facility contains a competitive bid option, whereby participating lenders bid on the interest rate to be charged. This feature is available for up to 50% of the amount of the revolving credit facility. There were $310.0 million borrowings outstanding under the revolving credit facility and $100.0 million borrowings under the delayed draw term loan facility as of December 31, 2018. As of December 31, 2018, letters of credit to third parties totaling $8.3 million had been issued for the account of the Company under this Credit Facility. The Credit Facility contains financial covenants, certain of which are set forth below:


•	total debt to total assets may not exceed 0.60:1;


•	adjusted earnings before interest, taxes, depreciation and amortization to fixed charges may not be less than 1.50:1;


•	unsecured debt to unencumbered asset value must equal or be less than 60%


•	secured debt to total asset value must equal or be less than 35%; and


•	unencumbered adjusted net operating income to unsecured interest expense must equal or exceed 175%.

In October 2017, the Company entered into a credit agreement for a working capital facility for aggregate borrowings of up to $30 million. This facility has the same maturity date, facility fee, covenants and interest rate borrowing terms as the revolving credit facility described above. There were $1.8 million in borrowings outstanding under the working capital facility as of December 31, 2018.

Activity

In October 2017, the Company replaced its existing $800 million Credit Facility with a new $800 million revolving credit facility and a $100 million delayed draw term loan facility. Additionally, the Company entered into a working capital facility for aggregate borrowings of up to $30 million.

In December 2018, the Company entered into a £129.5 million mortgage loan secured by properties in the Company's United Kingdom reportable segment at an interest rate of 2.64%.

A summary of the Company's share option activity and related information for the year ended December 31, 2018 follows:

Table of Contents



	Options (000s)		Weighted Average Exercise Price
Outstanding January 1, 2018	1,581		$	34.97
Exercised	(151	)	32.83
Outstanding December 31, 2018	1,430		$	35.20
Exercisable at December 31, 2018	1,430		$	35.20

No new options were granted during the years ended December 31, 2018, 2017 and 2016. Exercise prices for options outstanding as of December 31, 2018 ranged from $20.32 to $39.59. At December 31, 2018, the weighted average remaining contractual life of the options outstanding and exercisable was 4.0 years.

During the years ended December 31, 2018, 2017 and 2016, the total intrinsic value of share options exercised (the difference between the market price at exercise and the price paid by the individual to exercise the option) was $1.4 million, $1.4 million and $3.5 million, respectively. As of December 31, 2018, 1.4 million options outstanding and exercisable had an exercise price lower than the closing price of the Company's common shares. The aggregate intrinsic value of these options was $9.6 million at that date. The total cash received from the exercise of options for the years ended December 31, 2018, 2017 and 2016 was $5.0 million, $6.7 million and $14.4 million, respectively.

As of December 31, 2018, there were no unrecognized compensation costs related to nonvested options granted under the Plan.

Long Term Incentive Shares ("LTI")

During January 2018, 2017 and 2016, restricted LTI share grants made under the Plan were valued at the grant date fair value, which is the market price of the underlying common shares. LTI share grants after February 2017 were valued at the average closing price of the Company's shares for the trading days included within the 30-calendar-day period prior to and including the date of grant. The shares vest over either a 3-year or 5-year period beginning with the first anniversary of the grant and subject to certain accelerated vesting due to the age and years of service of certain employees.

During 2018, 2017 and 2016, the Company granted restricted stock units to the executive officers pursuant to the Plan.

For the chief executive officer's 2016 and 2017 awards, a portion of the restricted stock units will vest up to 272% at the end of a 3-year period. For the chief executive officer's 2018 award, a portion of the restricted stock units will vest up to 250% at the end of a 3-year period. For the other executives, for awards in 2016, 2017 and 2018 a portion of the restricted stock units will vest up to 200% at the end of a 3-year period. A portion ("First Portion") of the award vests based on how the Company's total return compares to the average total returns of a selected group of peer companies. The grant date fair value of the First Portion was calculated based on a Monte Carlo simulation model and was determined to be 149%, 132% and 174% of the market value of a common share as of the grant date ("Market Value") for the chief executive officer and 125%, 105% and 136% of the Market Value for the other executives for the 2018, 2017 and 2016 grants, respectively. A separate grant was made to the Company's Chief Financial Officer in 2016 when he joined the Company, and the grant date fair value of this award's First Portion was determined to be 160% of the Market Value as of the grant date. The First Portion is amortized over the respective 3-year period subject to certain accelerated vesting due to the age and years of service of certain executive officers.

For the 2016 and 2017 awards, the second portion of the award for the executive officers, other than the Chief Financial Officer's 2016 award, vests at the end of three years based on continued employment. The second portion of the Chief Financial Officer's award vests ratably over three years. For the 2017 award, the second portion of the award for the executive officers vests at the end of three years based on continued employment.

The key assumptions used in the Monte Carlo simulations are as follows:



	Year Ended December 31,
	2018	2017	2016
Risk-free interest rate	2.39%	1.43%	1.01%
Volatility	19%	20%	19%

The volatility factor is based on the Company's historical daily share prices.

Share-based compensation cost related to restricted LTI share grants for the years ended December 31, 2018, 2017 and 2016 was $11.1 million, $11.3 million and $12.2 million, respectively.

Bonus Shares

During the years ended December 31, 2018, 2017 and 2016, the Plan provided that employees of the Company could elect to receive bonuses or commissions in the form of common shares in lieu of cash ("Bonus Shares"). By making such election, the employee received shares equal to 120% of the cash value of the bonus or commission, for up to $50,000 of such bonus or commission, and 100% thereof for amounts exceeding $50,000, in each case reduced by applicable withholding tax. Bonus Shares issued for the years ended December 31, 2018, 2017 and 2016 were 41,620, 51,416 and 140,376, respectively.

Employee Share Purchase Plan

The Company registered 750,000 common shares under the Securities Act of 1933, as amended, in connection with an employee share purchase plan ("ESPP").

Operating ground lease expense incurred by the Company during the years December 31, 2018, 2017 and 2016 totaled $1.5 million, $0.1 million and $1.0 million, respectively.

Legal Matters

From time to time, the Company is a party to a variety of legal proceedings, claims and assessments arising in the normal course of business. The Company believes that as of December 31, 2018 there were no legal proceedings, claims or assessments expected to have a material adverse effect on the Company’s business or financial statements.

Other

As of December 31, 2018, the Company had letter of credit obligations of $8.3 million related to development requirements. The Company believes that it is remote that there will be a draw upon these letter of credit obligations.

As of December 31, 2018, the Company had 29 buildings under development. These buildings are expected to contain a total of 8.2 million square feet of leaseable space and represent an anticipated aggregate investment of $735.0 million. At December 31, 2018, Development in Progress totaled $472.2 million. In addition, as of December 31, 2018, the Company had invested $13.2 million in deferred leasing costs related to these development buildings.

As of December 31, 2018, the Company was committed to $13.0 million in improvements on certain buildings and land parcels.

As of December 31, 2018, the Company was obligated to pay for tenant improvements not yet completed for a maximum of $17.8 million.

As of December 31, 2018, the Company was committed to $49.5 million in future land purchases which it expects to complete during the year ended December 31, 2019.

As of December 31, 2018, the Company was developing two buildings for its unconsolidated joint ventures which represented an anticipated aggregate investment by the joint ventures of $235.8 million.

Two unconsolidated joint ventures in which the Company holds an interest have engaged the Company as the developer of the Comcast Technology Center (the “Project") pursuant to a Development Agreement by which the Company agrees, in consideration for a development fee, to be responsible for all aspects of the development of the Project and to guarantee the timely lien-free completion of construction of the Project as well as the payment, subject to certain exceptions, of any cost overruns incurred in the development of the Project. To mitigate its risk, the Company entered into guaranteed maximum price contracts with a third party contractor (the "GMP Contracts") to construct the Project. As discussed in Note 7, the Company has been notified by its third-party contractor that the contractor has incurred cost overruns and expects to incur additional construction costs in connection with completing the Project in excess of the guaranteed maximum price payable to the contractor under the GMP Contracts, which guaranteed maximum price has been previously adjusted pursuant to accepted change orders. The Company intends to pursue all remedies to recover from the third-party contractor any amounts expended by the Company or the joint ventures in excess of their contractual obligations. However, the general contractor has generally refused to fund these additional costs, and the Company has begun to fund and may continue to fund cost overruns in compliance with its obligations under its development cost guarantee to the joint ventures. As of December 31, 2018 and December 31, 2017, the Company had accrued $67.3 million and $5.6 million, respectively, relating to the above-described development cost guarantees which are included in other liabilities in the accompanying consolidated balance sheets.

Table of Contents

In addition to the costs to comply with the Company's obligations under its development cost guarantee, claims have been asserted by the third-party contractor and certain subcontractors. There can be no assurances that amounts incurred, including as a result of such claims, will not exceed the above estimates. The Company is not able to reasonably estimate the amount of additional expenses, if any, that it may incur as a result of such claims, and accordingly any potential exposure of the Company for such claims is not included within the accrual described above. If the Company were to incur additional expenses in connection with its development cost guarantee or in connection with such claims, such amounts would be accrued when they are determined to be probable of being incurred and are reasonably estimable, and could be material to the Company’s results of operations in future periods. If the Company were to subsequently recover any of the cost overruns initially funded by the Company, such recoveries would be recorded when and if realized in future periods.

As of December 31, 2018, the Company was also committed to approximately $170.9 million in costs related to its agreement to develop, on a fee basis, an office building and infrastructure improvements for American Water Works in Camden, New Jersey. As of December 31, 2018, $159.2 million of these costs had been incurred.

The Company maintains cash and cash equivalents at financial institutions. The combined account balances at each institution typically exceed FDIC insurance coverage and, as a result, there is a concentration of credit risk related to amounts on deposit in excess of FDIC insurance coverage. The Company believes the risk is not significant.

19. ACCOUNTING FOR THE IMPAIRMENT OR DISPOSAL OF LONG-LIVED ASSETS

In 2017, the Company initiated a strategic shift whereby it plans to divest of its remaining suburban office properties. In 2018, the Company updated its strategy whereby it plans to divest of its remaining office properties. The Company determined that the strategic shift would have a major effect on its operations and financial results. As such, properties sold or those that meet the criteria to be classified as held for sale within the new corporate strategy were classified within discontinued operations. Consistent with the held for sale criteria these properties are expected to be sold within one year. As the result of the classification within discontinued operations, the in-service assets and liabilities of this portfolio are required to be presented as held for sale for all prior periods presented in our Consolidated Balance Sheets. Operating results pertaining to these properties were reclassified to discontinued operations for all prior periods presented in our Consolidated Statements of Comprehensive Income.

The following table illustrates the number of sold or held-for-sale properties included in, or excluded from, discontinued operations in this report:



	Held for Sale as of December 31, 2018	Sold during the year ended December 31, 2018	Sold during the year ended December 31, 2017	Total

Interest expense has been allocated to discontinued operations. The allocation of interest expense to discontinued operations was based on the ratio of net assets sold and held for sale (without continuing involvement) to the sum of total net assets plus consolidated debt.

Capital expenditures on a cash basis for the year ended December 31, 2018, 2017 and 2016 were $6.1 million, $62.4 million and $18.9 million, respectively, related to properties within discontinued operations.

In October 2016, the Company completed the sale of a portfolio of 108 properties totaling approximately 7.6 million square feet and 26.7 acres of land for $969 million for a net gain of $179.1 million. As this sale did not represent a strategic shift for the Company, it is not classified as discontinued operations.

A summary of net income (excluding gain on sale) related to this portfolio is as follows (in thousands):

Asset Impairment

The Company evaluates its real estate investments upon the occurrence of significant adverse changes in operations to assess whether any impairment indicators are present that could affect the recovery of the recorded value. In addition to other factors it considers as described in Note 2 - Summary of Significant Accounting Policies, the Company considers strategic divestiture decisions that have either resulted in the disposition or potential disposition of certain properties prior to the end of their remaining useful lives. As a result, during the years ended December 31, 2018, 2017 and 2016, the Company recognized impairment losses of $39.7 million, $10.6 million and $3.9 million, respectively. The impairment losses are for operating properties or land parcels and were in the reportable segments and for the amounts as indicated below (in thousands):



	Year Ended December 31,

Consistent with its strategy to divest its remaining office properties and focus its efforts and capital solely on its industrial platform, the Company evaluated its office properties and land holdings in the latter part of 2018, and as a result, recognized impairment losses on certain properties which the Company is either holding for sale and/or it is planning to sell. For the year ended December 31, 2018, the Company recorded an impairment charge of $7.3 million relating to one office property held for sale which is included in discontinued operations, and impairments of $6.4 million relating to certain land holdings, which is included in impairment - real estate assets in the Company's consolidated statements of comprehensive income.

In addition, the Company recorded an impairment of $26.0 million related to its Camden Waterfront project located in Camden, New Jersey which is included in impairment - real estate assets in the Company's consolidated statements of comprehensive income. The Company evaluated the recoverability of the carrying value of its total investment in the Camden Waterfront project in 2018. Factors considered in evaluating the carrying value of this project included probability weighted projections of future cash flows, which are influenced by management’s judgments regarding the site configuration, absorption rates and timing of future fee development projects, the amount, timing and sunset provisions of government incentives aimed at inducing office users to relocate to Camden, and general market conditions affecting demand for office space in Camden. As a result of changes to management’s estimates of probability weighted future cash flow impacted by the above-described factors during the second quarter of 2018, the Company concluded that an indicator of impairment existed and the Company may not recover the carrying value of its investment in the Camden Waterfront project. As such, the Company recorded the impairment charge in the second

quarter of 2018. The impairment charge was equal to the amount by which the Company estimated the carrying value of its total investment in the Camden Waterfront project exceeded the current estimated fair value of its investment.

For the year ended December 31, 2017, $6.7 million in impairments related to properties sold were included in discontinued operations and $3.9 million in impairment - real estate assets related to land held for development. Consistent with the Company’s strategy to divest suburban office properties in 2017, as discussed above, properties and related land were disposed of before the end of their estimated useful lives at a time when the market price was below the Company’s net investment in the properties.

For the year ended December 31, 2016, $3.9 million in impairments related to properties sold.

The Company determined the above-described impairments based on third party offer prices and quoted offer prices for comparable transactions which are Level 2 and Level 3 inputs, respectively, according to the fair value hierarchy established in ASC 820. These measurements have occurred throughout the respective periods as circumstances arise, and the resulting estimates of fair value are not necessarily reflective of measurements at the period’s end.

The Company has evaluated each of its properties and land held for development and has determined that there were no additional valuation adjustments necessary at December 31, 2018. The Company applied reasonable estimates and judgments in determining the level of impairments recognized. Should external or internal circumstances change requiring the need to shorten the holding periods or adjust the estimated future cash flows of the Company’s assets, the Company could be required to record impairment charges in the future.

20. DERIVATIVE INSTRUMENTS

The Company borrows funds at a combination of fixed and variable rates. Borrowings under the Company's Facilities and certain bank mortgage loans bear interest at variable rates. Our long-term debt typically bears interest at fixed rates. The Company's interest rate risk management objectives are to limit generally the impact of interest rate changes on earnings and cash flows and to lower the Company's overall borrowing costs. To achieve these objectives, from time to time, the Company enters into interest rate hedge contracts such as collars, swaps, caps and treasury lock agreements in order to mitigate our interest rate risk with respect to various debt instruments. The Company generally does not hold or issue these derivative contracts for trading or speculative purposes. The interest rate on all of the Company's variable rate debt is generally adjusted at, daily, one or three month intervals, subject to settlements under interest rate hedge contracts.

Cash Flow Hedges of Interest Rate Risk

The Company determines the fair value of its interest rate derivatives by using the standard methodology of netting discounted future fixed cash payments with the discounted expected variable cash receipts. These variable cash receipts of interest rate derivatives are based on expectations of future interest rates (forward curves) estimated by observing market interest rate curves. This is a Level 2 fair value calculation. Also, credit valuation adjustments are factored into the fair value calculations to account for potential nonperformance risk. These credit valuation adjustments were concluded to be not significant inputs for the fair value calculations for the periods presented.

During 2017 and a portion of 2018, the Company held an interest in three interest rate swap contracts (“Swaps”) that eliminate the impact of changes in interest rates on the payments required under variable rate mortgages that were also assumed. The Swaps had aggregate notional amounts of $66.8 million and $96.2 million at December 31, 2018 and 2017, respectively, and two of the Swaps expire in 2020. One interest rate swap contract and related mortgage loan were repaid in April 2018 on the maturity date.

In 2018, in anticipation of conducting an offering of senior notes, the Operating Partnership entered into two interest rate lock agreements tied to the U.S. treasury rate for an aggregate notional amount of $200 million. An interest rate lock is a tool used to manage interest-rate risk by effectively securing interest rates on federal government securities as of the agreement date, to cover future expenses that will be financed by a debt offering. One agreement had a notional amount of $100 million and expired in 2018 and was settled for $2.4 million. The second agreement had a notional amount of $100 million and expired in 2019. It was settled prior to consummation of the January 2019 offering of senior notes for $3.3 million. See Note 21 - Subsequent Events.

The Company accounts for the effective portion of changes in the fair value of a derivative in accumulated other comprehensive loss and subsequently reclassifies the effective portion to earnings over the term that the hedged transaction affects earnings. The Company accounts for the ineffective portion of changes in the fair value of a derivative directly in earnings.

Total		$	4,649	$	2,243

Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s variable-rate debt. The Company estimates that $8,000 will be reclassified from accumulated other comprehensive loss as a decrease to interest expense over the next twelve months.

The Company has agreements with its derivative counterparties that contain a provision whereby if the Company defaults on any of its indebtedness, including defaults where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default on its derivative obligations. If the Company were to breach any of the contractual provisions of the derivative contracts, it would be required to settle its obligations under the agreements at their termination value including accrued interest for approximately $4.7 million.

Amounts paid in cash for deferred leasing costs incurred in connection with signed leases with tenants are paid in conjunction with improving (acquiring) property, plant and equipment. Such costs are not contained within net real estate. However, they are integral to the completion of a tenant lease and ultimately are related to the improvement and thus the value of the Company’s property, plant and equipment. They are therefore included in investing activities in the Company’s consolidated statements of cash flows.

The following is a reconciliation of the Company's cash and cash equivalents and restricted cash at the beginning and end of the years ended December 31, 2018 and 2017 (amounts in thousands):
