PART I


ITEM 1.	BUSINESS

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, 2004, the Company’s portfolio consisted of 723 industrial and office properties (the “Properties in Operation”) totaling approximately 61.7 million square feet. In addition, at that date, the Company had 16 properties under development, which when completed will add 1.7 million square feet to the Company’s portfolio, (the “Properties Under Development” and, together with the Properties in Operation, the “Properties”), and owned 1,108 acres of land, substantially all zoned for commercial use. Included above are 30 properties comprising 3.6 million square feet and 142 acres of developable land owned by unconsolidated joint ventures.

The Company provides leasing, property management, development, acquisition and other tenant-related services for the Properties in Operation. The Company’s 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. The Company’s office Properties are multi-story and single-story office buildings located principally in suburban mixed-use developments or office parks. Substantially all of the Company’s Properties are located in prime business locations within established business communities. In January 2005, the Company commenced development of a 1.2 million square foot office tower in Philadelphia’s central business district.

The Trust is the sole general partner and also a limited partner of the Operating Partnership, owning 95.9% of the common equity of the Operating Partnership at December 31, 2004. 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”). The Common Units held by the limited partners were exchangeable for approximately 3.7 million Common Shares on December 31, 2004. The Company has issued Series B, C, and D Cumulative Redeemable Preferred Units of the Operating Partnership (the “Preferred Units”). The Preferred Units are exchangeable on a one-for-one basis after a stated date into Cumulative Redeemable Preferred Shares. Collectively, the ownership of the holders of Common and Preferred Units is reflected on the Trust’s financial statements as minority interest.

In October 2004, the Company’s executive offices were relocated from 65 Valley Stream Parkway, Malvern, Pennsylvania 19355 to 500 Chesterfield Parkway, Malvern, Pennsylvania 19355. The telephone number remains (610) 648-1700.

In addition to this annual report on Form 10-K, the Company files periodic and current reports, proxy statements and other information with the SEC. The Company makes these documents available on its website, www.libertyproperty.com, free of charge, as soon as reasonably practicable after such material is electronically filed with, or furnished to, the SEC. You may also read and copy any document the Company files with the SEC at the SEC’s Public Reference Room at 450 Fifth Street, NW, Washington, DC 20549. Please call the SEC at (800) SEC-0330 for further information about the public reference facilities. These documents also may be accessed through the SEC’s electronic data gathering, analysis and retrieval system (“EDGAR”) via electronic means, including the SEC’s home page on the Internet, www.sec.gov.

Also posted on the Company’s website is the Company’s Code of Conduct, which applies to all of its employees and also serves as a code of ethics for its chief executive officer, chief financial officer and persons performing similar functions. The Company will send the Code of Conduct, free of charge, to anyone who requests a copy in writing to its Investor Relations Department at the address set forth above.

Management and Employees

The Company’s 422 employees (as of March 1, 2005) are under the direction of 19 senior executives, who, on average, have been affiliated with the Company and the Predecessor for 15 years. The Company and the Predecessor have developed and managed commercial real estate for the past 32 years. The Company’s in-house leasing and property management staff operates in markets where it has a significant presence. This structure enables the Company 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. At December 31, 2004, the Company’s reportable segments were based on the Company’s method of internal reporting and are as follows:

Business Objective and Strategies for Growth

The Company’s business objective is to maximize long-term profitability for its shareholders by being a recognized leader in commercial real estate through the ownership, management, development, and acquisition, of superior office and industrial properties. The Company intends to achieve this objective through offering office and industrial properties in multiple markets and operating as a leading landlord in the industry. The Company believes that this objective will provide the benefits of enhanced investment opportunities, economies of scale, risk diversification both in terms of geographic market and real estate product type, access to capital, and the ability to attract and retain personnel. The Company also strives to be a leading provider of customer service, providing an exceptional and positive customer experience. 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
The Company strives to be a recognized quality provider of five products (industrial properties, including big box warehouse, multi-tenant industrial, and flex/R&D; and office properties, including single-story office and multi-story office). When the Company’s marketing efforts identify opportunities, the Company will, in appropriate instances, pursue other office and industrial product types including high rise office towers. In January 2005, the Company commenced development of a 1.2 million square foot office tower in Philadelphia’s central business district.

Markets
The Company operates primarily in the Mid-Atlantic, Southeastern and Midwestern United States. Additionally, the Company owns certain assets in the United Kingdom. The Company’s goal is to operate in each of its markets with an appropriate product mix of office and industrial properties. The Company seeks to have a presence that allows it to be viewed as a significant participant in each market. The Company’s efforts emphasize business park development and asset aggregation. The Company gathers information from internal sources and independent third parties and analyzes this information to support its evaluation of markets and market conditions.

Organizational Plan
The Company seeks to maintain a management organization which 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 regarded real estate company through recruiting, training, and retaining capable people. The structure is designed to support a local office entrepreneurial platform operating within a value-added corporate structure.

The Company upgrades its information technology periodically to keep pace with advances in available technology. The Company commenced a process in 2003 of implementing an enterprise resource planning system. The system was launched in 2004 and the implementation throughout the Company was ongoing in 2004 and will continue in 2005.

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 the operating costs of the Properties and maintain the long-term value of the Properties.

Customer Service Initiatives
The Company seeks to achieve high tenant retention through a comprehensive customer service program, which is designed to provide an exceptional and positive customer 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 customer satisfaction.

External Growth Strategies
The Company seeks to enhance its long-term profitability through the development, acquisition and disposition of properties.

Development
The Company pursues attractive development opportunities, focusing primarily on high-quality suburban industrial and office properties within its existing markets. When the Company’s marketing efforts identify opportunities, the Company will pursue urban opportunities and development opportunities outside of the Company’s established markets. The Company and its Predecessor have developed over 46 million square feet of commercial real estate during the past 32 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% leased prior to commencement of construction). The Company develops build-to-suit projects for existing and new tenants. The Company also builds properties for inventory where the Company has identified sufficient demand at market rental rates to justify such construction.

During the year ended December 31, 2004, the Company completed 11 build-to-suit projects, two build-to-suit expansions, one inventory project, and one inventory expansion totaling approximately 1.4 million square feet of leaseable space and representing an aggregate Total Investment, as defined below, of approximately $104.2 million. As of December 31, 2004, these completed development properties were approximately 99.6% leased. The “Total Investment” for a Property is defined as the Property’s purchase price plus closing costs and management’s estimate, as determined at the time of acquisition, of the cost of necessary building improvements in the case of acquisitions, or land costs and land and building improvement costs in the case of development projects, and, where appropriate, other development costs and carrying costs.

As of December 31, 2004 the Company had 16 Properties Under Development which are expected to generate, upon completion, approximately 1.7 million leaseable square feet and are expected to represent a Total Investment of approximately $143.9 million. Approximately 14.4% of such leaseable space was pre-leased as of December 31, 2004. The scheduled deliveries of the 1.7 million square feet of leaseable space in Properties Under Development are as follows (in thousands, except percentages):


	Square Feet								Percent Leased			Total
Scheduled In-Service Date	Ind-Dist.		Ind-Flex		Office		Total		December 31, 2004			Investment
1^st Quarter 2005		–		59		31		90		78.7	%	$	8,721

Total		976		201		508		1,685		14.4	%	$	143,896

In addition to the above, in January 2005, the Company commenced development of a 1.2 million square foot office tower in Philadelphia’s central business district. Comcast Corporation has signed a 15¹/2 year lease for 534,000 square feet of space. The office tower, to be known as Comcast Center, is expected to be completed in late 2007.

The Company believes that, because it is a fully integrated real estate firm, its base of commercially zoned land in existing industrial and office business parks provides a competitive advantage for future development activities. As of December 31, 2004, the Company owned 1,108 acres of land held for development, substantially all 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 anticipates that its land holdings would support, as and when developed, approximately 12.5 million leaseable square feet, including the Comcast Center described above. The Company’s investment in land held for development as of December 31, 2004 was $171.1 million.

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

During the year ended December 31, 2004, the Company acquired 20 properties comprising approximately 3.9 million leaseable square feet for a Total Investment of $235.8 million.

The Company disposes of Properties and land held for development which no longer fit within the Company’s strategic plan, or with respect to which the Company believes it can optimize cash proceeds. During the year ended December 31, 2004, the Company sold ten Properties in Operation, which contained 760,000 square feet of leaseable space, and eight parcels of land, for an aggregate of $59.6 million.

Joint Ventures
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 its capital requirements. In some instances, joint venture partnerships provide the Company with additional local market or product type expertise. As of December 31, 2004, the Company had investments in unconsolidated joint ventures, totaling $24.4 million. In addition, the Company has an investment in consolidated joint ventures which own assets approximating $41.0 million. Interest held by others in these consolidated joint ventures is reflected as minority interests.

United Kingdom Operations
The Company’s United Kingdom operation includes 15 Properties in Operation and one development property which are located in a 650-acre, mixed commercial and residential community in the County of Kent, England. The community known as “Kings Hill” is located approximately 25 miles southeast of London. The community has been developed over the past decade by a joint initiative between the County of Kent and Rouse Kent Limited (“RKL”). During 2003, the Company exercised its option to purchase RKL for nominal consideration. The development agreement with the County of Kent allows RKL to develop additional commercial space and to participate in proceeds from the sale of residential land parcels to homebuilders. Subject to obtaining appropriate planning consents, further expansion of this community may take place.

The Company has also invested in two joint ventures to develop projects in separate locations in England and one joint venture which owns a Property in Operation. The Company believes that its development expertise, its access to capital and its relationship with tenants engaged in international business will create opportunities to service the needs of these tenants in both the United States and the United Kingdom. To date, these joint ventures have been entered into with established real estate developers in the United Kingdom.

The Company continues to pursue its investment in Kings Hill and to identify other development and acquisition opportunities in the United Kingdom.

Subsequent Events

The Company intends to continue to pursue its development, acquisition and disposition strategies. The Company is currently in various stages of discussions and negotiations with respect to development, acquisition and disposition projects. The consummation of these or any other future developments, acquisitions or dispositions, if any, and the pace at which developments may be completed and acquisitions and dispositions made cannot be guaranteed.

Risk Factors

The Company’s results from operations and the ability to make distributions to our shareholders and pay debt service on 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 on page 4.

Risks Related to Our Business

Unfavorable events concerning our existing tenants, or negative market conditions that may affect our existing 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 and inhibit growth.
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 facts 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 or reduced demand for 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

At any time, any of our tenants may experience a downturn in its business that may weaken its financial condition. As a result, a tenant may delay lease commencement, fail to make rental payments when due, decline to extend a lease upon its expiration, become insolvent or declare bankruptcy. Any tenant bankruptcy or insolvency, leasing delay or failure to make rental payments when due could result in the termination of the tenant’s lease and material losses to our Company.

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 shareholders and service our indebtedness.

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 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 insurance, cleaning, electricity, heating, ventilation and air conditioning, general and administrative costs and other costs associated with security, landscaping, repairs and maintenance of our Properties. 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 at the same time 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 where warranted by market conditions. The decline in demand for real estate has reduced the amount of development we are undertaking. We have a number of ongoing development projects and a number of land projects being readied for development. These projects include the Comcast Center, a 1.2 million square foot office tower in Philadelphia’s central business district, which is discussed below.

Additionally, 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 for that property
	•	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 because we may not be able to increase rents to compensate for the increase in construction costs
	•	some developments may fail to achieve expectations, possibly making them unprofitable
	•	we may be unable to obtain, or 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 determine to alter or discontinue our development efforts, past and future costs of the investment may 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 which we do not complete
	•	occupancy rates and rents at newly completed properties may fluctuate depending on a number of factors, including market and economic conditions, and may result in lower than projected rental rates with the result that our investment is not profitable

Our Comcast Center project (previously known as the “One Pennsylvania Plaza” project) is subject to a number of risks related to its development, construction, financing and leasing.
The Company has announced the commencement of the development of a 1.2 million square foot, 57 story office tower in Philadelphia. Construction on the office tower, to be known as the Comcast Center, began in January 2005 and is expected to be complete in late 2007. Comcast Corporation has signed a 15-1/2 year lease and will initially occupy 534,000 square feet, or approximately 44%, of the building’s rentable space. Comcast Corporation has options to increase its occupancy up to 800,000 square feet, or approximately 66%, of the building. The total project cost to be incurred by Liberty is expected to be $435 million.

The project is subject to substantial leasing risk as to the portion of the building not leased to Comcast. The Philadelphia office market generally contains substantial vacancy and has recently experienced a highly competitive leasing environment. Many of the premier office properties in the central business district contain significant vacancy. These conditions have had an adverse impact on market rental rates. Nevertheless, the Company believes that because of the unique features of this state-of-the-art commercial office building, sufficient demand exists from lease expirations of large commercial tenants in Philadelphia’s central business district during the 2006 to 2009 time frame and from prospective new tenants to the market to lease the remainder of the building at suitable rental rates.

Development of a project such as Comcast 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 associated with undertaking a construction project with the engineering and design complexities of an office tower.

The project also bears the investment risk that the market value of this 1.2 million square foot office tower may not support the construction costs of $360 per square foot. Recent sales prices for several modern office towers, which were constructed on average 15 years ago, in Philadelphia’s central business district, are estimated to be an average price of $183 per square foot. The Company believes that the investment value of the completed and leased Comcast Center supports the investment that will be made by the Company.

We face risks associated with property acquisitions.
We acquire individual properties and portfolios of properties, and intend to continue to do so. Our acquisition activities and their success are subject to the following risks:

	•	when we are able to locate a desired 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
	•	we may be unable to quickly and efficiently integrate new acquisitions, particularly acquisitions of portfolios of properties, 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 in the Mid-Atlantic, Southeastern and Midwestern United States. Due to the concentration of our Properties in these areas, performance is dependent on economic conditions in these areas. These areas have experienced periods of economic decline.

We may not be able to access financial markets to obtain capital on a timely basis, or on acceptable terms.
In order to qualify as a REIT for federal income tax purposes, we are required to distribute at least 90% of taxable income to shareholders each year, and thus cannot reinvest this portion of income in the business. As a result, retained cash flows are somewhat limited and we may rely on proceeds from Property dispositions and third party capital sources for a portion of our capital needs, including capital for acquisitions and development. The public debt and equity markets are among the sources we rely on. There is no guarantee that we will be able to access these markets, or any other source of capital. The 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 like 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 the portfolio declines. If the economic performance 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 $450 million credit facility and unsecured notes, as well as, at December 31, 2004, approximately $123.0 million in outstanding mortgage indebtedness, contain cross-default and/or cross-acceleration provisions, which means that a default on one obligation may constitute a default on other obligations.

We anticipate that only a small portion of the principal of our debt will be repaid prior to maturity. Therefore, we generally need to refinance our outstanding debt as it matures. There is a risk that we may not be able to refinance existing debt or that the terms of any refinancing will not be as favorable as the terms of our existing debt. If principal payments due at maturity cannot be refinanced, extended or repaid with proceeds from other sources, such as the proceeds of sales of assets or new equity securities, our cash flow will not be sufficient to repay all maturing debt in years when significant “balloon” payments come due.

Our credit facility and unsecured debt securities contain customary restrictions, requirements and other limitations on our ability to incur indebtedness, including total debt to 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 $450 million credit facility is subject to compliance with our financial and other covenants. In addition, our failure to comply with such covenants could cause a default under this credit

facility, 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 or affect the market price of our common stock.
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 current shareholders.
The interests of our existing shareholders could be diluted if we issue additional equity securities to finance future developments, acquisitions, or repay indebtedness. The Board of Trustees may issue 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.

An increase in interest rates would increase our interest costs on variable rate debt and could adversely impact our ability to refinance existing debt.
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.

Property ownership through joint ventures will limit our ability to act exclusively in our interests.
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 be sufficient to fully protect us against actions contrary to our interests. If the objectives of our co-venturers are inconsistent with ours, we may not in every case be able to act exclusively in our interests.

We may suffer economic harm if our enterprise resource planning software causes business interruptions.
In 2004 we launched an enterprise resource planning system for our business and its implementation throughout the Company was ongoing in 2004 and will continue in 2005. The objective of the new information technology system is to improve our performance by achieving a number of specific financial and operational measures. The new information technology system has been designed to provide us with a stable, long-term platform enabling us to deliver value to our tenants through information sharing and electronic commerce as these issues become more important in future periods.

Enterprise resource planning implementations are challenging initiatives that carry substantial project risk including the risk of business interruption. Failure to properly implement the new information technology system could have an adverse impact on our operating results.

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 Properties promptly in response to economic or other conditions. In addition, provisions of the Internal Revenue 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 carry insurance coverage on our Properties of the type and in amounts that we believe are in line with coverage customarily obtained by owners of similar properties. We believe all of our Properties are adequately insured. However, we cannot guarantee that the limits of our current policies will be sufficient in the event of a catastrophe to

our Properties. Our existing property and liability policies expire in May 2005. 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 environmental 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.

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.

It is our policy to retain independent environmental consultants to conduct Phase I environmental site assessments and asbestos surveys with respect to our acquisition of properties. 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 did 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

While we test indoor air quality on a regular basis and have an ongoing maintenance program in place to address this aspect of property operations, inquiries about indoor air quality may necessitate special investigation and, depending on the results, remediation. Indoor air quality issues can stem from inadequate ventilation, chemical contaminants from indoor or outdoor sources, pollen, viruses and bacteria. 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.
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. Concern about indoor exposure to mold has been increasing as 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 U.S. 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 States interests generally, may negatively affect our operations and your investment 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 the United States and worldwide financial markets and 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 Internal Revenue Code (the “Code”), as to which there are only limited judicial or administrative interpretations. The complexity of these provisions and of the related income tax 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 Internal Revenue 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 facility, 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 cause our Board of Trustees to revoke our election to qualify as a REIT. This decision requires the consent of the holders of a majority of the voting interests of all of our outstanding Common Shares.

Risks associated with potential borrowings necessary to make distributions to qualify as a REIT.
We intend to make distributions to shareholders to comply with the distribution provisions of the Code necessary to maintain qualification as a REIT and to avoid income taxes and the non-deductible excise tax. Under certain circumstances, we may be required to borrow funds to meet the distribution requirements necessary to achieve the tax benefits associated with qualifying as a REIT. In such circumstances, we might need to borrow funds to avoid adverse tax consequences, even if our management believes that the prevailing market conditions are not generally favorable for such borrowings or that such borrowings would not be advisable in the absence of such tax considerations.

Certain officers of the Trust may not have the same interests as shareholders as to certain tax laws.
Certain officers of the Trust own Common Units. These units may be exchanged for our Common Shares. The 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

The Trust also owns units in the Operating Partnership. Because the Trust, as well as the certain officers who own units, face different consequences than shareholders do, the Trust and those 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 the Board of Trustees. This limitation could prevent the acquisition of control of the Company by a third party without the consent from the Board of Trustees.

We have a staggered board and certain restrictive nominating procedures. The Board of Trustees has three classes of trustees. The term of office of one class expires each year. Trustees for each class are elected for three-year terms as that class’ term expires. The terms of the Class II, Class III, and Class I trustees expire in 2005, 2006, and 2007, respectively. Any nominee for trustee must be selected under the nominating provisions contained in our Declaration of Trust and By-Laws. The staggered terms for trustees and the nominating procedures may affect shareholders’ ability to take control of the Company, even if a change in control were in the shareholders’ interest.

The Company can issue preferred shares. Our Declaration of Trust authorizes the 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.

We have a poison pill. Under the shareholder rights plan, rights are issued along with each of the Trust’s Common Shares. Holders of these rights can purchase, under certain conditions, a portion of a preferred share of beneficial interest, or receive Common Shares, or common shares of an entity acquiring us, or other consideration, having a value equal to twice the exercise price of the right. The exercise price of the right is $200. This arrangement is often called a “poison pill.” Our poison pill could have the effect of delaying or preventing a change of control of the Company, even if a change in control were in the shareholders’ 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.
General market conditions could worsen. 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 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.

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.

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.

ITEM 3.	LEGAL PROCEEDINGS

The ownership of property and provision of services to the public entails an inherent risk of liability. Although the Company is engaged in litigation incidental to its business, there is no legal proceeding to which it is a party which, in the opinion of management, will materially adversely affect the results of the Company’s operations. The Company carries liability insurance against certain types of claims that management believes meets industry standards; however, there can be no assurance that any future legal proceedings (including any related judgments, settlements or costs) will not materially adversely affect the Company’s financial condition, liquidity, or results of operations.


ITEM 4.	SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

No matters were submitted to a vote of security holders during the fourth quarter of the year ended December 31, 2004.

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 “LRY.” There is no established public trading market for the Common Units. The following table sets forth, for the calendar quarters indicated, the high and low closing prices of the Common Shares on the New York Stock Exchange, and the dividends declared per Common Share for such calendar quarter.


					Dividends
					Declared Per
	High		Low		Common Share

Second Quarter		34.91		30.72		0.60
First Quarter		32.30		28.91		0.60

As of March 1, 2005, the Common Shares were held by 1,269 holders of record. Since its initial public offering, the Company has paid regular and uninterrupted quarterly dividends.

Although the Company currently anticipates that comparable cash dividends will continue to be paid in the future, 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 Internal Revenue Code of 1986, as amended, and such other factors as the Board of Trustees deems relevant.


ITEM 6.	SELECTED FINANCIAL DATA

The following table sets forth Selected Financial Data for Liberty Property Trust and Liberty Property Limited Partnership as of and for the years ended December 31, 2004, 2003, 2002, 2001 and 2000. The information set forth below should be read in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the financial statements and notes thereto appearing elsewhere in this report.

(3)	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-GAAP financial measure on a per share basis in its Release No. 34-47226, Conditions for Use of Non-GAAP Financial Measures. The Company believes that the calculation of 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 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 Funds from operations provides useful information to the investment community about the Company’s financial performance when compared to other REIT’s since Funds from operations is generally recognized as the standard for reporting the operating performance of a REIT. Funds from operations available to common shareholders is defined by NAREIT as net income (computed in accordance with generally accepted accounting principles (“GAAP”)), excluding gains (or losses) from sales of property, plus depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. Funds from operations available to common shareholders does not represent net income or cash flows from operations as defined by 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. Funds from operations available to common shareholders also does not represent cash flows generated from operating, investing or financing activities as defined by GAAP. A reconciliation of Funds from operations to Net Income may be found on page 31.

ITEM 7.	MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

The Company has an ownership interest in and operates 443 industrial and 280 office properties located primarily in the Mid-Atlantic, Southeastern and Midwestern United States (the “Properties in Operation”) totaling 61.7 million square feet. In addition, as of December 31, 2004, the Company has 16 properties under development (the “Properties under Development” and together with the Properties in Operation the “Properties”) and owns 1,108 acres of land, substantially all of which is zoned for commercial use. Included above are 30 properties comprising 3.6 million square feet and 142 acres of developable land owned by unconsolidated joint ventures.

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 increasing rental rates. The Company pursues development opportunities that it believes will create value and yield acceptable returns. The Company also acquires properties which it believes will create long-term value, and disposes of Properties which 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.

In 2004 the Company continued to experience the effects of the generally slow real estate economy that has persisted since 2002. This economy has presented a particularly difficult real estate market for landlords. These circumstances impacted many aspects of the Company’s business.

The Properties in Operation, which represent over 95% of the Company’s revenue, were subjected to market conditions characterized by an oversupply of leaseable space and soft demand. These conditions resulted in downward pressure on rental rates and upward pressure on lease transaction costs related to tenant inducements (e.g. tenant improvement costs). In the face of these conditions, the Company successfully leased 12.8 million square feet and attained occupancy of 91.9%, which it believes represents performance which is substantially better than market. However, in spite of the increase in occupancy, due to the decreases in rental rates for renewal and replacement leases, property level operating income for the “Same Store” properties (properties owned since January 1, 2003) declined for 2004 when compared to 2003 by 1.2% on a straight line basis and 1.1% on a cash basis. See further discussion of Same Store results below. The Company believes that these trends for the Properties in Operation (i.e., oversupply of leaseable space, downward pressure on rents, upward pressure on transaction costs), which have persisted in 2003 and 2004 will continue in the aggregate in 2005, notwithstanding improvements in some markets. Although rental rates in certain markets are starting to stabilize, generally rents on renewal or replacement leases will be less than rents on expiring leases.

Conditions in 2004 for the acquisition of properties were very competitive. The Company, however, acquired 20 buildings representing 3.9 million square feet and a Total Investment of $235.8 million. These acquisitions generally served to increase the presence or balance the product mix in markets the Company believes to have significant potential. For 2005, the Company believes that property acquisitions will be in the $200 to $300 million range and, similar to 2004, many of the acquired properties will be either vacant or under leased. The Company believes that these properties are more attractively priced and will positively contribute to earnings upon lease up and stabilization.

Dispositions of Properties which no longer fit within the Company’s strategic objectives or in situations where it can optimize cash proceeds continued in 2004. During 2004, the Company sold $51.1 million in operating Properties. The Company anticipates that dispositions will be in the $75 to $150 million range in 2005.

In 2004, the Company continued to pursue development opportunities. In 2004, the Company brought into service $104.2 million of development properties and initiated $111.8 million in real estate development. The Company believes that in 2005 build-to-suit activity will continue and that conditions in certain markets may continue to support the initiation of inventory projects (i.e. projects that are less than 75% leased prior to the commencement of construction). In January 2005, the Company commenced construction of a 1.2 million square foot, $435 million office tower in Philadelphia’s central business district. Comcast Corporation has signed a lease for 534,000 square feet of space in this office tower.

Forward-Looking Statements

When used throughout this report, the words “believes,” “anticipates,” “hopes” 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 which 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 identify and secure additional properties and sites that meet its criteria for acquisition or development; the availability and cost of capital; the effect of prevailing market interest rates; and other risks described from time to time in the Company’s filings with the Securities and Exchange Commission (“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 accounting principles generally accepted in the United States. 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 Company believes the following critical policies affect its more significant estimates and assumptions used in the preparation of its consolidated financial statements.

Capitalized Costs
Expenditures directly related to the acquisition, or improvement of real estate, including interest and other costs capitalized on development 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 from the completion of major construction activity. The capitalized costs include pre-construction costs essential to the development of the property, construction costs, interest costs, real estate taxes, development related salaries and other costs incurred during the period of development. Capitalized development related salaries and benefits historically represent approximately 1% of the cost of developed properties brought into service. The determination to capitalize rather than expense costs requires the Company to evaluate the status of the development activity. Capitalized interest for the year ended December 31, 2004 was $13.2 million.

Allowance for Doubtful Accounts
The Company monitors the liquidity and creditworthiness of its tenants on an on-going basis. 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, 2004 and 2003, the Company’s allowance for doubtful accounts totaled $5.9 million and $5.7 million, respectively. For the year ended December 31, 2004, the Company’s bad debt expense totaled $2.4 million as compared to $1.8 million for the year ended December 31, 2003, or 0.4% of operating revenue for 2004 compared to 0.3% for 2003.

Impairment of Real Estate
The Company evaluates its real estate investments upon occurrence of significant adverse changes in operations to assess whether any impairment indicators are present that affect the recovery of the recorded value. If any real estate investment is considered impaired, the carrying value of the property is written down to its estimated fair value. During the years ended December 31, 2004 and 2002, the Company recognized impairment losses of $1.4 million and $11.3 million. The 2004 impairment loss of $1.4 million was on a parcel of land in the Midwest region. The 2002 impairment loss included $5.3 million related to three parcels of land and an impairment loss of $6.0 million on assets held for sale. This loss was subsequently realized later in 2002 upon the disposal of those assets held for sale. The determination of whether impairment exists requires the Company to make estimates, judgments and assumptions about the future utility of the assets. The Company has evaluated each of the properties and land held for development and has determined that there are no additional valuation adjustments that need to be made at December 31, 2004.

Intangibles
In accordance with the Financial Accounting Standards Board (“FASB”) Statement of Financial Standards (“SFAS”) No. 141, “Business Combinations,” the Company allocates the purchase price of real estate 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 fair 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 market rates. The Company depreciates the amounts allocated to building and improvements over 40 years and the amounts allocated to intangible assets relating to in-place leases, which are included in deferred financing and leasing costs in the accompanying balance sheet, over the remaining term of the related leases. In the event that a tenant terminates its lease, the unamortized portion of the intangible is charged to expense.

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, 2004 with the results of operations of the Company for the year ended December 31, 2003, and the results of operations of the Company for the year ended December 31, 2003 with the results of operations of the Company for the year ended December 31, 2002. As a result of the varying level of development, acquisition and disposition activities by the Company in 2004 and 2003, the overall operating results of the Company during such periods are not directly comparable. However, certain data, including the Same Store 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, 2004 to Year Ended December 31, 2003.
The Company’s average gross investment in operating real estate owned for the year ended December 31, 2004 increased to $4,064.2 million from $3,733.2 million at December 31, 2003. This increase resulted from the increased investment in real estate acquired or developed, partially offset by Property dispositions. This increased investment in operating real estate resulted in increases in rental revenue, rental property operating expenses and real estate taxes, and depreciation and amortization expense.

Total operating revenue increased to $655.4 million for the year ended December 31, 2004 from $620.3 million for the year ended December 31, 2003. This $35.1 million increase was primarily due to the net increase in investment in real estate. Partially offsetting this increase was a decrease in “Termination fees,” which totaled $10.9 million for the year ended December 31, 2004 as compared to $14.1 million for the same period in 2003. “Termination Fees” are fees that the Company has agreed to accept in consideration for permitting certain tenants to terminate their leases prior to the contractual expiration date. Termination Fees are included in rental revenue.

The Company evaluates the performance of the Properties in Operation by reportable segment (see Note 13 to the Company’s financial statements). The property level operating income for the Lehigh Valley, Mid-Atlantic and United Kingdom segments increased by 9.3%, 8.9% and 50.2%, respectively, for the year ended December 31, 2004 as compared to 2003. There was no significant change in property level operating income for the Company’s other segments. The increase in the Lehigh Valley segment is due to the delivery of $99.2 million in completed developments during 2003 and 2004 and property acquisitions of $71.8 million in 2004. The increase in the Mid-Atlantic segment resulted from $131.9 million in property acquisitions that were made during 2003 and 2004. Acquisitions and completed development in 2003 contributed to property level operating income for a partial period in 2003 as compared to a full year in 2004. The increase in the United Kingdom segment is due to the purchase of Rouse Kent Limited on July 1, 2003.

Property level operating income, exclusive of Termination Fees, for the Same Store properties decreased to $399.8 million for the year ended December 31, 2004 from $404.6 million for the year ended December 31, 2003, on a straight line basis (which recognizes rental revenue evenly over the life of the lease), and decreased to $391.1 million for the year ended December 31, 2004 from $395.6 million for the year ended December 31, 2003 on a cash basis. These decreases of 1.2% and 1.1%, respectively, were primarily due to decreases in rental rates. At December 31, 2004, the occupancy of the Same Store portfolio increased to 93.2% as compared to 92.4% at December 31, 2003.

Management generally considers the performance of the Same Store properties to be a useful financial performance measure because the results are directly comparable from period to period. Management further believes that the performance comparison should exclude Termination Fees since they are more event specific and are not representative of ordinary performance results. In addition, Same Store property level operating income exclusive of Termination Fees is considered, by management, to be a more reliable indicator of the portfolio’s baseline performance. The Same Store properties consist of the 631 properties totaling approximately 49.7 million square feet owned since January 1, 2003.

Set forth below is a schedule comparing the property level operating income, on a straight line basis and on a cash basis, for the Same Store properties for the years ended December 31, 2004 and 2003. Same Store property level income is a non-GAAP measure and does not represent income before property dispositions, income taxes and minority interest because it does not reflect the consolidated operations of the Company. Investors should review Same Store results, along with Funds from operations (see Liquidity and Resource section), GAAP net income and cash flow from operating activities, investing activities and financing activities when trying to understand the Company’s operating performance. Also, set forth below is a reconciliation of Same Store property level operating income to net income.

Discontinued operations, net of minority interest		12,746			14,292

Net income	$	161,443		$	163,610

General and administrative expenses increased to $33.3 million for the year ended December 31, 2004 from $28.4 million for the year ended December 31, 2003. These increases were primarily due to increases in salaries and increases in personnel consistent with the increase in the number of properties and the size of the Company. The increase in general and administrative expenses was also due to the expensing of stock options and related long term incentive compensation, an increase in cancelled project costs and increased costs relating to compliance with the requirements of the Sarbanes-Oxley legislation and related regulatory requirements.

Depreciation and amortization increased to $135.5 million for the year ended December 31, 2004 from $121.5 million for the year ended December 31, 2003. The increase was primarily due to the increase in gross investment in operating real estate during the respective periods and particularly the increased investment in leasing costs, which are amortized over a relatively shorter period than buildings and improvements.

Interest expense increased to $123.4 million for the year ended December 31, 2004 from $123.2 million for the year ended December 31, 2003. This increase was due to an increase in the average debt outstanding for the respective periods, which was $1,990.3 million in 2004 and $1,881.5 million in 2003. The effect of the increases in the average debt outstanding was offset by decreases in the weighted average interest rates for the periods, to 6.70% in 2004 from 6.93% in 2003.

Costs directly related to the development of rental properties and land being readied for development are capitalized. Capitalized development costs include interest, development related salaries, property taxes, insurance and other directly identifiable costs during the period of development. Capitalized interest for the year ended December 31,

2004 was $13.2 million as compared to $10.9 million for the year ended December 31, 2003. Capitalized development related salaries and benefits historically represent approximately 1% of the cost of developed properties brought into service.

As a result of the foregoing, the Company’s net income decreased to $161.4 million for the year ended December 31, 2004 from $163.6 million for the year ended December 31, 2003.

Comparison of Year Ended December 31, 2003 to Year Ended December 31, 2002.
The Company’s average gross investment in operating real estate owned for the year ended December 31, 2003 increased to $3,733.2 million from $3,407.9 million at December 31, 2002. This increase resulted from the increased investment in real estate acquired or developed, partially offset by Property dispositions. This increased investment in operating real estate resulted in increases in rental revenue, rental property operating expenses and real estate taxes, and depreciation and amortization expense.

Total operating revenue increased to $620.3 million for the year ended December 31, 2003 from $588.0 million for the year ended December 31, 2002. This $32.3 million increase was primarily due to the net increase in investment in real estate as discussed above. In addition, during 2003, the Company accepted Termination Fees totaling $14.1 million as compared to $8.4 million for the same period in 2002. Termination Fees are included in rental revenue.

The Company evaluates the performance of the Properties in Operation by reportable segment (see Note 13 to the Company’s financial statements). The property level operating income for the United Kingdom and Florida segments increased by 43.1% and 14.3%, respectively, for the year ended December 31, 2003 as compared to 2002. The increase in the United Kingdom was due to the purchase of Rouse Kent Limited on July 1, 2003. The increase in Florida was due to an increase in occupancy during 2003 as compared to 2002. These increases were partially offset by a decrease in the operating results of the Delaware Valley segment due to the disposition of Properties during the fourth quarter of 2002 to Liberty Venture I, LP (see Note 4 to the Company’s financial statements).

Property level operating income, exclusive of Termination Fees, for the “Prior Year Same Store” (as defined below) properties decreased to $377.6 million for the year ended December 31, 2003 from $385.9 million for the year ended December 31, 2002, on a straight line basis and decreased to $370.5 million for the year ended December 31, 2003 from $377.5 million for the year ended December 31, 2002 on a cash basis. These decreases of 2.1% and 1.9%, respectively, were primarily due to decreases in occupancy. At December 31, 2003, the occupancy of the Prior Year Same Store portfolio was flat as compared to December 31, 2002 at 92.4%.

Management generally considers the performance of the Prior Year Same Store properties to be a useful financial performance measure because the results are directly comparable from period to period. Management further believes that the performance comparison should exclude Termination Fees since they are more event specific and are not representative of ordinary performance results. In addition, Prior Year Same Store property level operating income exclusive of Termination Fees is considered, by management, to be a more reliable indicator of the portfolio’s baseline performance. The Prior Year Same Store properties consist of the 603 properties totaling approximately 46.6 million square feet owned since January 1, 2002.

Set forth below is a schedule comparing the property level operating income, on a straight line basis and on a cash basis, for the Prior Year Same Store properties for the years ended December 31, 2003 and 2002. Prior Year Same Store property level income is a non-GAAP measure and does not represent income before property dispositions, income taxes and minority interest because it does not reflect the consolidated operations of the Company. Investors should review Prior Year Same Store results, along with Funds from operations (see Liquidity and Resource section), GAAP net income and cash flow from operating activities, investing activities and financing activities when trying to understand the Company’s operating performance. Also, set forth below is a reconciliation of Prior Year Same Store property level operating income to net income.

General and administrative expenses increased to $28.4 million for the year ended December 31, 2003 from $21.7 million for the year ended December 31, 2002. These increases are primarily due to costs relating to the Company’s investment in an enterprise resource planning initiative to update company wide accounting and business process software and due to the expense from the accelerated vesting of restricted stock and options related to the death of former Chairman Willard G. Rouse III.

Depreciation and amortization increased to $121.5 million for the year ended December 31, 2003 from $108.6 million for the year ended December 31, 2002. The increase is primarily due to the increase in gross investment in operating real estate during the respective periods and particularly the increased investment in leasing costs, which are amortized over a relatively shorter period that buildings and improvements.

Interest expense increased to $123.2 million for the year ended December 31, 2003 from $115.2 million for the year ended December 31, 2002. This increase is due to an increase in the average debt outstanding for the respective periods, which was $1,881.5 million in 2003 and $1,820.5 million in 2002. The effect of the increases in the average debt outstanding was partially offset by decreases in the weighted average interest rates for the periods, to 6.93% in 2003 from 7.09% in 2002.

Costs directly related to the development of rental properties and land being readied for development are capitalized. Capitalized development costs include interest, salaries, property taxes, insurance and other directly identifiable costs during the period of development. Capitalized interest for the year ended December 31, 2003 was $10.9 million as compared to $16.5 million for the year ended December 31, 2002. Capitalized development salaries and benefits historically represent approximately 1% of the cost of developed properties brought into service.

As a result of the foregoing, the Company’s net income increased to $163.6 million for the year ended December 31, 2003 from $161.7 million for the year ended December 31, 2002.

Liquidity and Capital Resources

As of December 31, 2004, the Company had cash and cash equivalents of $68.3 million, including $34.6 million in restricted cash.

Net cash flow provided by operating activities increased to $292.7 million for the year ended December 31, 2004 from $260.7 million for the year ended December 31, 2003. This $32.0 million increase was due to increased cash flow from operating properties due to the greater number of properties owned in 2004 compared to 2003 and also due to fluctuations in operating assets and liabilities during the respective periods. Net cash flow provided by operations is the primary source of liquidity to fund distributions to shareholders and for the recurring capital expenditures and leasing transaction costs for the Company’s Properties in Operation.

Net cash used in investing activities increased to $373.3 million for the year ended December 31, 2004 from $192.0 million for the year ended December 31, 2003. This $181.3 million increase primarily resulted from an increased investment in properties and an increased investment in development in progress compared to 2003.

Net cash provided by financing activities was $89.6 million for the year ended December 31, 2004 compared to $58.1 million used for the year ended December 31, 2003. This $147.7 million change was primarily due to the issuance of unsecured notes in 2004 and increased net borrowings on the credit facility offset by a decrease in net proceeds from the issuance of common shares. Net cash provided by or used by financing activities includes proceeds from the issuance of equity and debt, net of debt repayments and shareholder distributions, and the redemption of preferred shares. Cash provided by financing activities is a source of capital utilized by the Company to fund investment activities.

The Company funds its development and acquisitions with long-term capital sources including proceeds from the disposition of Properties. For the year ended December 31, 2003, these activities were funded through a $350 million Credit Facility (the “$350 million Credit Facility”). In December 2004, the borrowing capacity of the $350 million Credit Facility was increased to $450 million (the “new $450 million Credit Facility”). The interest rate on borrowings under the credit facilities fluctuate based upon ratings from Moody’s Investors Service, Inc. (“Moody’s”), Standard and Poor’s Ratings Group (“S&P”) and Fitch, Inc. (“Fitch”). The current ratings for the Company’s senior unsecured debt are Baa2, BBB and BBB from Moody’s, S&P and Fitch, respectively. At these ratings, the interest rate for borrowings under the new $450 million Credit Facility is 70 basis points over LIBOR. The new $450 million Credit Facility expires in January 2006, and has a one year extension option.

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 earnings to fixed charge coverage ratio. As of December 31, 2004 the Company’s debt to gross assets ratio was 43.9%, and for the year ended December 31, 2004, the earnings to fixed charge coverage ratio was 2.9x. Debt to gross assets equals total long-term debt and borrowings under the new $450 million Credit Facility divided by total assets plus accumulated depreciation. Earnings to fixed charges equals income from continuing operations before property dispositions and minority interest, including operating activity from discontinued operations, plus interest expense and depreciation and amortization, divided by interest expense, including capitalized interest, plus distributions on preferred shares and units.

As of December 31, 2004, $366.2 million in mortgage loans and $1,455.0 million in unsecured notes were outstanding with a weighted average interest rate of 7.2%. The interest rates on $1,745.6 million of mortgage loans and unsecured notes are fixed and range from 6.0% to 8.8%. Interest rates on $75.6 million of mortgage loans float with the base rate of the respective lending bank or a municipal bond index. The weighted average remaining term for the mortgage loans and unsecured notes is 5.7 years.

In 2005, $146.4 million in mortgage loans with various interest rates will mature. The Company anticipates that it will refinance or retire these maturities through its available sources of capital.

The Company’s contractual obligations, as of December 31, 2004, are as follows (in thousands):

In January 2005, the Company commenced construction of a 1.2 million square foot, $435 million office tower in Philadelphia’s central business district. Comcast Corporation has signed a 15¹/2 year lease for 534,000 square feet of space in this office tower (“Comcast Center”). The Company has entered into a Guaranteed Maximum Price contract for the construction of the Comcast Center. Construction costs covered by this contract represent approximately 60% of the estimated $435 million in total development costs.

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 Property dispositions and net cash provided from operating activities. Additionally, the Company expects to incur variable rate debt, including borrowings under the new $450 million Credit Facility from time to time.

In December 2003, the Company received approximately $99.5 million in net proceeds from the issuance of 2.7 million Common Shares. The Company used the net proceeds from the issuance of Common Shares to pay down borrowings under the $350 million Credit Facility which had been used to fund development and acquisition activity.

In August 2004, the Company issued $200 million of ten year 5.65% senior unsecured notes. The proceeds from this issuance were used to repay $100 million of 7.1% senior unsecured notes which matured on August 15, 2004, pay down outstanding borrowings under the Company’s $350 million Credit Facility, acquire properties and for general corporate purposes.

In September 2004, the quarterly Common Share dividend was increased to $0.61 per share from $0.605 per share. The Company’s annual Common Share dividend paid was $2.425 per share, $2.405 per share, and $2.37 per share in 2004, 2003, and 2002, respectively. In 2004, the Company’s dividend payout ratio was approximately 75% of Funds from operations (as defined below).

In February 2005, the Company consummated the sale of $300 million principal amount of 5.125% senior unsecured notes due 2015. The aggregate net proceeds from such issuance was approximately $296.4 million. The Company used the aggregate net proceeds to pay down outstanding borrowings under the new $450 million Credit Facility and for general corporate purposes.

The Company has an effective S-3 shelf registration statement on file with the SEC (the “Shelf Registration Statement”). As of March 1, 2005, pursuant to the Shelf Registration Statement, the Trust had the capacity to issue up to $586.1 million in equity securities and the Operating Partnership had the capacity to issue up to $306.2 million in debt securities.

Investment in Unconsolidated Joint Ventures
As of December 31, 2004, the Company had investments in unconsolidated joint ventures, totaling $24.4 million.

Calculation of Funds from Operations
The National Association of Real Estate Investment Trusts (“NAREIT”) has issued a standard definition for Funds from operations (as defined below). The SEC has agreed to the disclosure of this non-GAAP financial measure on a per share basis in its Release No. 34-47226, Conditions for Use of Non-GAAP Financial Measures. The Company believes that the calculation of 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 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 Funds from operations provides useful information to the investment community about the Company’s financial performance when compared to other REIT’s since Funds from operations is generally recognized as the standard for reporting the operating performance of a REIT. Funds from operations available to common shareholders is defined by NAREIT as net income (computed in accordance with generally accepted accounting principles (“GAAP”)), excluding gains (or losses) from sales of property, plus depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. Funds from operations available to common shareholders does not represent net income or cash flows from operations as defined by 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.

Funds from operations available to common shareholders also does not represent cash flows generated from operating, investing or financing activities as defined by GAAP. Funds from operations (“FFO”) available to common shareholders for the years ended December 31, 2004, 2003, and 2002 are as follows (in thousands, except per share amounts):

Inflation
Inflation has remained relatively low during the last three years, and as a result, it has not had a significant impact on the Company during this period. The new $450 million Credit Facility bears interest at a variable rate; therefore, the amount of interest payable under the new $450 million Credit Facility will be influenced by changes in short-term interest rates, which tend to be sensitive to inflation. To the extent an increase in inflation would result in increased operating costs, such as in insurance, real estate taxes and utilities, substantially all 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 Company’s primary market risk exposure is to changes in interest rates.

The Company is exposed to market risk related to its new $450 million 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 interest on the new $450 million Credit Facility and such other indebtedness is subject to fluctuations in the market.

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 a forecasted issuance of new debt. In order to reduce interest rate risk associated with these transactions, the Company occasionally enters into interest rate protection agreements.

If the interest rates for variable rate debt were 100 basis points higher or lower during 2004, the Company’s interest expense would have been increased or decreased by approximately $3.3 million. If the interest rate for the fixed rate debt maturing in 2005 was 100 basis points higher or lower than its current rate of 7.6%, the Company’s interest expense would be increased or decreased by approximately $620,000.

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.

The Company is also exposed to currency risk on its $150.9 million net investment in the United Kingdom. The Company does not believe that this currency risk exposure is material to its financial statements.


ITEM 8.	FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

The dual presentation of financial statements for the Company is required by the Securities and Exchange Commission. The Company is comprised of two Securities and Exchange Commission registrants: Liberty Property Trust and Liberty Property Limited Partnership. Accordingly, financial statements are required for each registrant. The financial information contained within the two sets of financial statements is essentially the same.

Management’s Annual Report on Internal Control Over Financial Reporting

To the Shareholders of Liberty Property Trust:

The Company’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 Company’s internal control system was designed to provide reasonable assurance to the Company’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 Company’s internal control over financial reporting as of December 31, 2004. In making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commissions (COSO) inInternal Control — Integrated Framework. Based on our assessment we believe that, as of December 31, 2004, the Company’s internal control over financial reporting is effective based on those criteria.

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.

Report of Independent Registered Public Accounting Firm

The Board of Trustees and Shareholders of Liberty Property Trust

We have audited management’s assessment, included in the accompanying Management Report on Internal Control Over Financial Reporting, that Liberty Property Trust (the “Trust”) maintained effective internal control over financial reporting as of December 31, 2004, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). The Trust’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on management’s assessment and an opinion on the effectiveness of the Trust’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

In our opinion, management’s assessment that Liberty Property Trust maintained effective internal control over financial reporting as of December 31, 2004, is fairly stated, in all material respects, based on the COSO criteria. Also, in our opinion, the Trust maintained, in all material respects, effective internal control over financial reporting as of December 31, 2004, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Liberty Property Trust as of December 31, 2004 and 2003, and the related consolidated statements of operations, shareholders’ equity, and cash flows for the each of the three years in the period ended December 31, 2004 of the Trust and our report dated February 28, 2005 expressed an unqualified opinion thereon.

An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Liberty Property Trust at December 31, 2004 and 2003, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2004, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of Liberty Property Trust’s internal control over financial reporting as of December 31, 2004, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 28, 2005 expressed an unqualified opinion thereon.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS OF LIBERTY PROPERTY TRUST


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 95.9% of the common equity of the Operating Partnership at December 31, 2004. The Company provides leasing, property management, development, acquisition, and other tenant-related services for a portfolio of industrial and office properties which are located principally within the Mid-Atlantic, Southeastern, and Midwestern United States.


2.	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates
The preparation of financial statements in conformity with U.S. generally accepted accounting principles 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 and 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 minority shareholders. All significant intercompany transactions and accounts have been eliminated.

Reclassifications
Certain amounts from prior years have been reclassified to conform to current-year presentation.

Real Estate and Depreciation
The Properties are recorded at the lower of cost or fair value and are depreciated using the straight line method over their estimated useful lives. The estimated useful lives are as follows:


Buildings and improvements		40 years (blended)
Equipment		5-10 years
Tenant improvements		Term of the related lease

Expenditures directly related to acquisition, or improvement of real estate, including interest and other costs capitalized during development, are included in net real estate and are stated at cost. The capitalized costs include pre-construction costs essential to the development of the property, development and construction costs, interest costs, real estate taxes, salaries and other costs incurred during the period of development. Expenditures for maintenance and repairs are charged to operations as incurred.

In accordance with the Financial Accounting Standards Board (“FASB”) Statement of Financial Standards (“SFAS”) No. 141, “Business Combinations,” the Company allocates the purchase price of real estate 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 market rent for leases of similar terms and present valuing the difference based on market interest rates. Origination values are also assigned to in-place leases, and, where appropriate, value is assigned to customer relationships. The Company depreciates the amounts allocated to building and improvements over 40 years and the amounts allocated to intangible assets relating to in-place leases, which are included in deferred financing and leasing costs in the accompanying balance sheet, over the remaining term of the related leases.

The Company evaluates its real estate investments upon occurrence of a significant adverse change in its operations to assess whether any impairment indicators are present that affect the recovery of the recorded value. 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.

Investment in Unconsolidated Joint Ventures
The Company accounts for its investments in unconsolidated joint ventures under 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 Consolidated Balance Sheet and the Company’s share of net income from the joint venture is included on the Consolidated Statement of Operations.

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.

Accounts Receivable
The Company’s accounts receivable are comprised of rents and charges for property operating costs due from tenants. The accounts 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.

Deferred Rent Receivable
The Company’s deferred rent receivable represents the cumulative difference between rent revenue recognized on a straight line basis and contractual payments under the terms of tenant leases.

Revenues
The Company earns rental income under operating leases with tenants. Rental income is recognized on a straight line basis over the applicable 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.

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 in accordance with Staff Accounting Bulletin 101 when the following conditions are met:

	a)	the termination agreement is executed,
	b)	the termination fee is determinable,
	c)	all landlord services, pursuant to the terminated lease, have been rendered,
	d)	collectibility of the termination fee is assured.

Deferred Financing and Leasing Costs
Costs incurred in connection with financing or leasing are capitalized and amortized over the term of the related loan or lease. Deferred financing cost amortization is reported as interest expense. Intangible assets related to acquired in-place leases are amortized over the terms of the related leases.

Income per Common Share
The following table sets forth the computation of basic and diluted income per common share (in thousands, except per share amounts):

Diluted income per common share
Income available to common shareholders and assumed conversions	$	150,237			76,272	$	1.97

Fair Value of Financial Instruments
The carrying value of cash and cash equivalents, restricted cash, accounts receivable and accounts payable are reasonable estimates of fair values because of the short-term maturities of these investments. The fair value of the Company’s long-term debt, which is based on estimates by management and on rates quoted on December 31, 2004 for comparable loans, exceeds the aggregate carrying value by approximately $233.8 million at December 31, 2004.

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 90% of its REIT taxable income (95% for the years prior to January 1, 2001), as defined in the Code, to its shareholders and satisfies certain other requirements. The Company has met these requirements and, accordingly, no provision has been made for federal income taxes in the accompanying consolidated financial statements.

Several of the Company’s subsidiaries are taxable REIT subsidiaries and are subject to federal income taxes. The Company is also taxed in certain states and the United Kingdom. Accordingly, the Company has recognized federal, state and United Kingdom income taxes in accordance with US GAAP, as applicable.

The Federal tax cost basis of the real estate at December 31, 2004 was approximately $4.5 billion.

Stock-Based Compensation
At December 31, 2004, the Company had a share-based employee compensation plan as fully described in Note 10. Prior to 2003, the Company accounted for the plan under the recognition and measurement provisions of APB Opinion No. 25, “Accounting for Stock Issued to Employees,” and related Interpretations. No share-based employee compensation cost was reflected in the 2002 net income, as all options granted under this plan had an intrinsic value of zero on the date of grant. Effective January 1, 2003, the Company adopted the fair value recognition provisions of the Financial Accounting Standards Board’s (“FASB”) Statement of Financial Accounting Standards (“SFAS”) No. 123, “Accounting for Stock-Based Compensation,” prospectively for all employee option awards granted, modified, or settled after January 1, 2003. Option awards under the Company’s plan vest over three years. Therefore, the cost related to share-based employee compensation included in the determination of net income for 2004, 2003 and 2002 is less than that which would have been recognized if the fair value based method had been applied to all option awards since the original effective date of SFAS No. 123.

Foreign Currency Translation
The functional currency for the Company’s United Kingdom operations is pounds sterling. The Company translates their financial statements into US dollars. Gains and losses resulting from this translation do not impact the results of operations and are included in accumulated other comprehensive income as a separate component of shareholders’ equity.

Newly Issued Accounting Standards
In December 2004, the FASB issued SFAS No. 123(R), “Share-Based Payment.” SFAS No. 123(R) is a revision of SFAS No. 123 “Accounting for Stock-Based Compensation,” and supersedes Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees,” and amends SFAS No. 95 “Statement of Cash Flows.” SFAS No. 123(R) eliminates the ability to account for share-based compensation transactions using APB Opinion No. 25 and requires all share-based payments to employees, including grants of employee stock options, to be recognized in the financial statements using a fair value-based method. Effective January 1, 2003, the Company elected to adopt fair value accounting for stock-based compensation consistent with SFAS No. 123 using the prospective method with guidance provided by SFAS No. 148. SFAS No. 123(R) is effective as of the beginning of the first interim period that begins after June 15, 2005. The Company will adopt SFAS No. 123(R) as required in the fourth quarter of 2005 and expect that its effect will not be material to the Company’s consolidated financial statements.

In November 2004, the Emerging Issues Task Force of the FASB reached a tentative conclusion regarding EITF 04-05, “Investor’s Accounting for an Investment in a Limited Partnership When the Investor is the Sole General Partner and the Limited Partners Have Certain Rights.” In question is what rights held by the limited partners preclude consolidation of the limited partnership by the sole general partner. The Company is the general partner of several unconsolidated joint ventures and currently does not consolidate these ventures in its financial results based primarily on certain rights of the limited partners. Depending on the outcome of the discussion of the Task Force in future meetings, the outcome could impact whether or not the Company consolidates these partnerships. See Note 4, “Investments in Unconsolidated Joint Ventures” for further information regarding the Company’s accounting for its investment in unconsolidated joint ventures.

4.	INVESTMENTS IN UNCONSOLIDATED JOINT VENTURES

On November 18, 2002, the Company entered into a joint venture agreement (“Liberty Venture I, LP”) with the Public Employees’ Retirement Association of Colorado. The Company sold or contributed 28 properties with a net book value of $127.5 million to the joint venture in exchange for a 25% ownership interest in the joint venture and $108.8 million in cash. The properties are industrial distribution properties in New Jersey (the Delaware Valley segment). The Company’s share of the joint venture earnings is included in equity in (loss) earnings of unconsolidated joint ventures in the accompanying statement of operations. The Company provides development, leasing and property management services for a fee, and may receive a promoted interest if certain return thresholds are met.

During the years ended December 31, 2004 and 2003, the joint venture purchased additional industrial distribution properties with net book values of approximately $5.5 million and $12.9 million, respectively.

During the year ended December 31, 2003, the Company exercised its option to purchase Rouse Kent Limited (“RKL”) for nominal consideration. As a result of the purchase, the Company’s assets and liabilities increased by approximately $60 million. The operations of RKL are included in the consolidated financial statements beginning July 1, 2003.

RKL owns six buildings which contain 210,000 square feet of leaseable space and has planning permission for the development of additional commercial space. RKL is party to a contract with the County of Kent which contract entitles RKL to participate in proceeds realized from the sale of residential land parcels to homebuilders.

Pursuant to agreements, the Company provided management services with respect to RKL for the six months ended June 30, 2003 for $300,000 and for the year ended December 31, 2002 for $600,000. In addition, the Company paid a fee to RKL for management services which it provided for the Company’s properties owned in the United Kingdom. For the six months ended June 30, 2003 the fees for these services were $223,000 and for the year ended December 31, 2002 the fee for these services were $662,000. The Company recognized interest income on notes receivable from RKL of $1.9 million for the six months ended June 30, 2003, and $3.3 million for the year ended December 31, 2002.


6.	INDEBTEDNESS

Indebtedness consists of mortgage loans, unsecured notes, and borrowings under the credit facility. The weighted average interest rates for the years ended December 31, 2004, 2003, and 2002, were approximately 6.7%, 6.9%, and 7.1%, respectively. Interest expense for the years ended December 31, 2004, 2003, and 2002, aggregated $123.4 million, $123.2 million, and $115.2 million, respectively. Interest costs during these periods of $13.2 million, $10.9 million, and $16.5 million, respectively, were capitalized. Cash paid for interest for the years ended December 31, 2004, 2003, and 2002, was $130.4 million, $132.5 million, and $128.4 million, respectively.

matured on August 15, 2004, pay down outstanding borrowings under the Company’s unsecured credit facility, acquire properties and for general corporate purposes.

The Company is subject to financial covenants contained in some of the debt agreements, the most restrictive of which are detailed below under the heading “Credit Facility”. As of December 31, 2004 the Company was in compliance with the financial covenants.

Mortgage Loans, Unsecured Notes
Mortgage loans with maturities ranging from 2005 to 2012 are collateralized by and in some instances cross-collateralized by properties with a net book value of $488.4 million.

As of December 31, 2004, $366.2 million in mortgage loans and $1,455.0 million in unsecured notes were outstanding. The interest rates on $1,745.6 million of mortgage loans and unsecured notes are fixed and range from 6.0% to 8.8%. Interest rates on $75.6 million of mortgage loans float with the base rate of the respective lending bank or a municipal bond index. The weighted average remaining term for the mortgage loans and unsecured notes is 5.7 years.

Credit Facility
For the year ended December 31, 2002, the Company utilized a $450 million unsecured credit facility (the “$450 million Credit Facility”). In January 2003, the $450 million Credit Facility was replaced with a $350 million Credit Facility (the “$350 million Credit Facility”). In December 2004, the Company exercised the accordion feature on its $350 million Credit Facility, increasing its capacity to $450 million (the “new $450 million Credit Facility”). The interest rate on borrowings under the new $450 million Credit Facility fluctuated based on the Company’s senior debt ratings from Moody’s Investors Service, Inc. (“Moody’s”), Standard & Poor’s Ratings Group (“S&P”) and Fitch, Inc. (“Fitch”). The current ratings for the Company’s senior unsecured debt are Baa2, BBB, and BBB from Moody’s, S&P, and Fitch, respectively. Based on these ratings, the interest rate on borrowings under the new $450 million Credit Facility is 70 basis points over the LIBOR rate (2.42% at December 31, 2004). There is also a 20 basis point facility fee on the current borrowing capacity. The new $450 million 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 $150 million of borrowings. The new $450 million Credit Facility expires on January 16, 2006 and may be extended for a one year period. The new $450 million Credit Facility contains financial covenants, certain of which are set forth below:

	•	total debt to total assets may not exceed 0.55:1;
	•	operating cash flows to interest may not be less than 1.85:1;
	•	earnings before interest, taxes, depreciation and amortization to fixed charges may not be less than 1.75:1;
	•	unencumbered asset value to unsecured debt may not be less than 175%; and
	•	unencumbered cash flow to unsecured debt service must exceed 1.5:1.

8.	SHAREHOLDERS’ EQUITY

Common Shares
The Company paid to holders of Common Shares and holders of Common Units distributions of $213.3 million, $196.2 million, and $186.1 million, during the years ended December 31, 2004, 2003, and 2002, respectively. On a per share basis, the Company paid Common Share and Unit distributions of $2.425, $2.405, and $2.37, during the years ended December 31, 2004, 2003, and 2002, respectively.

For federal income tax purposes, the following table summarizes the portions of the Common Share distributions relating to return of capital, ordinary income, and capital gains:


	2004			2003			2002
Return of capital		8.0	%		–			–
Ordinary income		87.3	%		96.0	%		91.6	%
Capital gains		4.7	%		4.0	%		8.4	%

The Company’s federal income tax returns are subject to examination by taxing authorities. Because the application of tax laws and regulations is susceptible to varying interpretations, the taxability of distributions could be changed at a later date upon final determination by taxing authorities.

Treasury Shares
The Board of Trustees authorized a share repurchase plan under which the Company may purchase up to $100 million of the Company’s Common Shares and preferred shares (as defined below).

Preferred Shares
The Series A Cumulative Redeemable Preferred Shares (the “Preferred Shares”), which were redeemed on August 28, 2002, were non-voting and had a liquidation preference of $25.00 per share. The Preferred Shares were redeemed for $125 million. In accordance with EITF Topic D-42, “The Effect on Calculation of Earnings per Share for the Redemption or Induced Conversion of Preferred Stock,” the excess of preferred redemption over carrying amount is classified as a reduction in income available to common shareholders for the year ended December 31, 2002.

The Company paid Preferred Share distributions of $9.1 million ($1.82 per share) for the year ended December 31, 2002.

For federal income tax purposes, the following table summarizes the portions of the preferred shares distributions relating to return of capital, ordinary income and capital gains:


	2002
Return of capital		–
Ordinary income		100.0	%
Capital gains		–

Minority Interest
Minority interest in the accompanying consolidated financial statements represents the interests of the Common and Preferred Units in Liberty Property Limited Partnership not held by the Trust. Minority interest is adjusted at each period end to reflect the ownership percentage of the Common and Preferred unitholders at that time. A minority interest reclassification occurs between minority interest and shareholders’ equity each period there is a transaction involving ownership interests in Liberty Property Limited Partnership. In addition, minority interest includes third-party ownership interests in two consolidated joint venture investments in the United Kingdom and one consolidated joint venture investment in the Midwest region. No Common Units were issued in connection with acquisitions in 2004 or 2002. During 2003, 33,682 Common Units were issued in connection with an acquisition. The Common Units outstanding as of December 31, 2004 have the same economic characteristics as would 3,667,832 Common Shares. The Common Units share proportionately in the net income or loss and in any distributions of the Operating Partnership and are exchangeable into the same number of Common Shares of the Trust.

The Company has outstanding the following Cumulative Redeemable Preferred Units of the Operating Partnership, (the “Preferred Units”):


Date
of						Liquidation	Dividend			Redeemable
Issue	Issue	Amount		Units		Preference	Rate			As of	Exchangeable after
		(in 000's)
7/28/99	Series B	$	95,000		3,800	$25		7.45	%	8/31/09	1/1/14 into Series B Cumulative Redeemable Preferred Shares of the Trust

Effective August 31, 2004, the rate on $95 million Series B preferred units was reduced from 9.25% to 7.45%.

The Company paid the following Preferred Unit distributions for the year ended December 31:


	2004		2003		2002
Distributions (in millions)	$	11.8	$	12.4	$	11.6

Series D	$	3.81	$	3.81	$	2.13

Shareholder Rights Plan
In December 1997, the Board of Trustees of the Company adopted a shareholder rights plan (the “Shareholder Rights Plan”). Under the Shareholder Rights Plan, one Right (as defined in the Shareholder Rights Plan) was attached to each outstanding Common Share at the close of business on December 31, 1997. In addition, a Right will be attached to each share of Common Stock issued in the future. Each Right entitles the registered holder to purchase from the Company, under certain conditions, a unit (a “Rights Plan Unit”) consisting of one one-thousandth of a share of a Series A Junior Participating Preferred Share, $0.0001 par value, (the “Junior Preferred Stock”), of the Company, for $100 per Rights Plan Unit, subject to adjustment. The Rights become exercisable only if a person or group of affiliated or associated persons (an “Acquiring Person”) acquires, or obtains the right to acquire, beneficial ownership of Common Shares or other voting securities (“Voting Stock”) that have 10% or more of the voting power of the outstanding shares of Voting Stock, or if an Acquiring Person commences to make a tender offer or exchange offer to acquire beneficial ownership of Voting Stock that has 10% or more of the voting power of the outstanding shares of Voting Stock. The Rights are redeemable by the Company at a price of $0.0001 per Right. If not exercised or redeemed, all Rights will expire on December 31, 2007.

Dividend Reinvestment and Share Purchase Plan
The Company has a Dividend Reinvestment and Share Purchase Plan under which holders of Common Shares may elect to automatically reinvest their distributions in additional Common Shares and may make optional cash payments for additional Common Shares. The Company may issue additional Common Shares or repurchase Common Shares in the open market for purposes of financing its obligations under the Dividend Reinvestment and Share Purchase Plan. During the years ended December 31, 2004, 2003, and 2002, 1,590,488, 2,056,482, and 1,693,837 Common Shares, respectively, were issued through the Dividend Reinvestment and Share Purchase Plan.


9.	EMPLOYEE BENEFIT PLANS

The Company maintains a 401(k) plan for the benefit of its full-time employees. The Company matches the employees’ contributions up to 3% of the employees’ salary and may also make annual discretionary contributions. Total 401(K) expense recognized by the Company was $739,000, $550,000, and $408,000 for the years ended 2004, 2003 and 2002, respectively.

The Company registered 750,000 common shares under the Securities Act of 1933, as amended, in connection with an employee share purchase plan (“ESPP”). The ESPP enables eligible employees to purchase shares of the Company at a 15% discount to fair market value. A total of 9,227, 9,766, and 8,977 common shares were issued, in accordance with the ESPP, during the years ended December 31, 2004, 2003, and 2002, respectively.


10.	SHARE OPTIONS

The Company’s Share Incentive Plan (“Share Incentive Plan”), as amended, has authorized the grant of options to executive officers, other key employees, non-employee trustees and consultants of up to 11,426,256 shares of the Company’s Common Shares. All options granted have 10-year terms and vest over a 3-year period, with options to purchase up to 20% of the shares exercisable after the first anniversary, up to 50% after the second anniversary and 100% after the third anniversary of the date of grant.

The cost related to share-based employee compensation included in the determination of net income for 2004, 2003 and 2002 is less than that which would have been recognized if the fair value based method had been applied to all option awards since the original effective date of SFAS No. 123.

The fair value for the employee option awards was estimated at the date of grant using a Black-Scholes option pricing model with the following weighted-average assumptions for 2004, 2003, and 2002:


	2004			2003			2002
Risk-free interest rate		4.0	%		5.0	%		5.0	%
Dividend yield		6.2	%		7.5	%		7.5	%
Volatility factor		.172			.175			.175
Weighted-average expected life	8 years			8 years			8 years

The following table illustrates the effect on net income and earnings per share if the fair value based method had been applied to all outstanding and unvested option awards in each period (in thousands, except per share amounts).

Pro forma income available to common shareholders	$	160,593		$	162,163		$	148,102

Income per common share:

Diluted – pro forma	$	1.87		$	2.03		$	1.94

Pro forma disclosures are not likely to be representative of the effects on reported net income for future years because of the staggered vesting periods of the options.

A summary of the Company’s share option activity, and related information for the years ended December 31, 2004, 2003, and 2002 follows:

Exercise prices for options outstanding as of December 31, 2004 ranged from $19.75 to $34.98. The weighted-average remaining contractual life of those options is 6.0 years.

Grants of 103,918, 115,987, and 44,134 restricted shares were made under the Share Incentive Plan during the years ended December 31, 2004, 2003 and 2002, respectively. These restricted shares vest ratably over a 5-year period beginning with the first anniversary date of the grant.

An additional 2,309,159, 1,241,632, and 1,691,578, Common Shares were reserved for issuance for future grants under the Share Incentive Plan at December 31, 2004, 2003 and 2002, respectively.


11.	COMMITMENTS AND CONTINGENCIES

Substantially all of the Properties and land were subject to Phase I Environmental Assessments and when appropriate Phase II Environmental Assessments (collectively, the “Environmental Assessments”) obtained in contemplation of their acquisition by the Company. The Environmental Assessments consisted of, among other activities, a visual inspection of each Property and its neighborhood and a check of pertinent public records. The Environmental Assessments did not reveal, nor is the Company aware of, any non-compliance with environmental laws, environmental liability or other environmental claim that the Company believes would likely have a material adverse effect on the Company.

Although the Company is engaged in litigation incidental to its business, there is no legal proceeding to which it is a party which, in the opinion of management, will materially adversely affect the results of the Company’s operations.

The Company is obligated to make additional capital contributions to unconsolidated joint ventures of approximately $3.7 million.

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.

14.	SFAS NO. 144, “ACCOUNTING FOR THE IMPAIRMENT OR DISPOSAL OF LONG-LIVED ASSETS”

Discontinued Operations
In accordance with SFAS No. 144 which the Company adopted on January 1, 2002, net income and gain/(loss) on disposition of real estate for properties sold subsequent to December 31, 2001 are reflected in the consolidated statements of operations as discontinued operations. The proceeds from dispositions of Operating Properties were $51.1 million and $40.8 million for the years ended December 31, 2004 and 2003, respectively. Below is a summary of the results of operations of the properties disposed of through the respective disposition dates (in thousands):


	December 31,
	2004			2003			2002
Revenues	$	4,778		$	7,549		$	11,405
Operating expenses		(922	)		(1,770	)		(2,519	)
Interest expense		(1,145	)		(1,179	)		(1,892	)
Depreciation and amortization		(1,018	)		(1,604	)		(2,272	)

Income before property dispositions and minority interest	$	1,693		$	2,996		$	4,722

Sales of land and development properties are reflected as a component of income from continuing operations.

Asset Impairment
In accordance with SFAS No. 144, during the years ended December 31, 2004 and 2002, the Company recognized impairment losses of $1.4 million and $11.3 million. The 2004 impairment loss of $1.4 million was on a parcel of land in the Midwest region. The 2002 asset impairment included $5.3 million related to three parcels of land and an impairment loss of $6.0 million on assets held for sale. This loss was subsequently realized later in 2002 upon the disposal of those assets held for sale. Asset impairments are included in the caption gain (loss) on property dispositions as a component of income from continuing operations. The Company determined this impairment through a comparison of the aggregate future undiscounted cash flows to be generated by the properties to the carrying value of the properties. The Company has evaluated each of the properties and land held for development and has determined that there are no additional valuation adjustments necessary at December 31, 2004.


15.	SUBSEQUENT EVENTS

On February 24, 2005, the Company consummated the sale of $300 million principal amount of 5.125% senior unsecured notes due 2015. The aggregate net proceeds from such issuance were approximately $296.4 million. The Company used the aggregate net proceeds primarily to pay down outstanding borrowings under the new $450 million Credit Facility and for general corporate purposes.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS OF
LIBERTY PROPERTY LIMITED PARTNERSHIP


1.	ORGANIZATION


2.	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation
The Consolidated Financial Statements of the Company include, the Trust, the Operating Partnership and 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 minority shareholders. All significant intercompany transactions and accounts have been eliminated.

Reclassifications
Certain amounts from prior years have been reclassified to conform to current-year presentation.


Buildings and improvements		40 years (blended)
Equipment		5-10 years
Tenant improvements		Term of the related lease

In accordance with the Financial Accounting Standards Board (“FASB”) Statement of Financial Standards (‘SFAS”) No. 141, “Business Combinations,” the Company allocates the purchase price of real estate 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 market rent for leases of similar terms and present valuing the difference based on market interest rates. Origination values are also assigned to in-place leases, and, where appropriate, value is assigned to customer relationships. The Company depreciates the amounts allocated to building and improvements over 40 years and the amounts allocated to intangible assets relating to in-place leases, which are included in Deferred financing and leasing costs in the accompanying balance sheet, over the remaining term of the related leases.

The Company evaluates its real estate investments upon occurrence of significant adverse changes in their operations to assess whether any impairment indicators are present that affect the recovery of the recorded value. If any real estate investment is considered impaired, a loss is provided to reduce the carrying value of the property to its estimated fair value.

Investment in Unconsolidated Joint Ventures
The Company accounts for its investments in unconsolidated joint ventures under 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 on the Consolidated Balance Sheet and the Company’s share of net income from the joint venture is included on the Consolidated Statement of Operations.

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

	e)	the termination agreement is executed,
	f)	the termination fee is determinable,
	g)	all landlord services, pursuant to the terminated lease, have been rendered,
	h)	collectibility of the termination fee is assured.

Deferred Financing and Leasing Costs
Costs incurred in connection with financing or leasing are capitalized and amortized over the term of the related loan or lease. Amortization of deferred financing costs is reported as interest expense. Intangible assets related to acquired in-place leases are amortized over the terms of the related leases.

Income Taxes
In conformity with the Internal Revenue Code and applicable state and local tax statutes, taxable income or loss of the Operating Partnership is required to be reported in the tax returns of the partners in accordance with the terms of the Partnership Agreement. However, the Company is taxed in certain states and the United Kingdom. Accordingly, the Company has recognized federal, state and local taxes in accordance with US GAAP, as applicable.

Newly Issued Accounting Standards
In November, 2004, the Emerging Issues Task Force of the FASB reached a tentative conclusion regarding EITF 04-05, “Investor’s Accounting for an investment in a Limited Partnership When the Investor is the Sole General Partner and the Limited Partners Have Certain Rights.” In question is what rights held by the limited partners preclude consolidation of the limited partnership by the sole general partner. The Company is the general partner of several unconsolidated joint ventures and currently does not consolidate these ventures in its financial results based primarily on certain rights of the limited partners. Depending on the outcome of the discussion of the Task Force in future meetings, the outcome could impact whether or not the Company consolidates these partnerships. See Note 4, “Investments in Unconsolidated Joint Ventures” for further information regarding the Company’s accounting for its investment in unconsolidated joint ventures.

Sales of land and development properties are reflected as a component of income from continuing operations.

Asset Impairment
In accordance with SFAS No. 144, during the years ended December 31, 2004 and 2002, the Company recognized impairment losses of $1.4 million and $11.3 million. The 2004 impairment loss of $1.4 million was on a parcel of land in the Midwest region. The 2002 asset impairment included $5.3 million was related to three parcels of land and an impairment loss of $6.0 million on assets held for sale. This loss was subsequently realized later in 2002 upon the disposal of those assets held for sale. Asset impairments are included in the caption gain (loss) on property dispositions as a component of income from continuing operations. The Company determined this impairment through a comparison of the aggregate future undiscounted cash flows to be generated by the properties to the carrying value of the properties. The Company has evaluated each of the properties and land held for development and has determined that there are no additional valuation adjustments necessary at December 31, 2004.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures
The Company’s management, with the participation of its Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of its disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act) as of the end of the period covered by this report. Based on this evaluation, the Company’s Chief Executive Officer and Chief Financial Officer have concluded that its disclosure controls and procedures, as of the end of the period covered by this report, are functioning effectively to provide reasonable assurance that information required to be disclosed by the Company in its reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Company in the reports that are filed or submitted under the Exchange Act is accumulated and communicated to the Company’s management, including its principal executive and principal financial officers, or persons performing similar function, as appropriate to allow timely decisions regarding required disclosure.

A controls system, no matter how well designed and operated, cannot provide absolute assurance that the objectives of the controls system are met, and no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within a company have been detected.
