EXPLANATORY NOTE

This report combines the quarterly reports on Form 10-Q for the period ended September 30, 2015 of Liberty Property Trust and Liberty Property Limited Partnership. Unless stated otherwise or the context otherwise requires, references to the “Trust” mean Liberty Property Trust and its consolidated subsidiaries, and references to the “Operating Partnership” mean Liberty Property Limited Partnership and its consolidated subsidiaries. The terms the “Company,” “we,” “our” and “us” mean the Trust and the Operating Partnership, collectively.

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

The Trust is the sole general partner and also a limited partner of the Operating Partnership, owning 97.7% of the common equity of the Operating Partnership at September 30, 2015. 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 financial results of the Operating Partnership are consolidated into the financial statements of the Trust. The Trust has no significant assets other than its investment in the Operating Partnership. The Trust and the Operating Partnership are managed and operated as one entity. The Trust and the Operating Partnership have the same managers.

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

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

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

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

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

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

• consolidated financial statements;

• the following notes to the consolidated financial statements;

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

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

This report also includes separate Item 4. Controls and Procedures sections and separate Exhibit 31 and 32 certifications for each of the Trust and the Operating Partnership in order to establish that the Chief Executive Officer and the Chief Financial Officer of each entity have made the requisite certifications and that the Trust and Operating Partnership are compliant with Rule 13a-15 and Rule 15d-15 of the Securities Exchange Act of 1934, as amended.

Liberty Property Trust and Liberty Property Limited Partnership

Notes to Consolidated Financial Statements (Unaudited)

September 30, 2015

Note 1: Organization and Basis of Presentation

Organization

Liberty Property Trust (the “Trust”) is a self-administered and self-managed Maryland real estate investment trust (a “REIT”). Substantially all of the Trust’s assets are owned directly or indirectly, and substantially all of the Trust’s operations are conducted directly or indirectly, by its subsidiary, Liberty Property Limited Partnership, a Pennsylvania limited partnership (the “Operating Partnership” and, together with the Trust and their consolidated subsidiaries, the “Company”). The Trust is the sole general partner and also a limited partner of the Operating Partnership, owning 97.7% of the common equity of the Operating Partnership at September 30, 2015. The Company owns and operates industrial properties nationally and owns and operates office properties in a focused group of office markets. Additionally, the Company owns certain assets in the United Kingdom. Unless otherwise indicated, the notes to the Consolidated Financial Statements apply to both the Trust and the Operating Partnership. The terms the “Company,” “we,” “our” and “us” mean the Trust and Operating Partnership collectively.

Basis of Presentation

The accompanying unaudited consolidated financial statements of the Company have been prepared in accordance with United States generally accepted accounting principles (“US GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by US GAAP for complete financial statements and should be read in conjunction with the consolidated financial statements and notes thereto included in the Annual Report on Form 10-K of the Company for the year ended December 31, 2014. In the opinion of management, all adjustments (consisting solely of normal recurring adjustments) necessary for a fair presentation of the financial statements for these interim periods have been included. The results of interim periods are not necessarily indicative of the results to be obtained for a full fiscal year.

As disclosed in Note 2, Income per Common Share of the Trust - Share Repurchase, the Company repurchased common shares pursuant to a share repurchase program authorized by the Company's Board of Trustees. These repurchased shares along with those repurchased in prior periods are subject to state corporate laws that establish the legal status of redeemed shares and prevent them from being reported as treasury shares within the consolidated financial statements. The Trust previously misclassified the repurchased shares as common shares in treasury. The share repurchases should have been classified as reductions of common shares of beneficial interest and additional paid-in capital. The accompanying consolidated balance sheet of the Trust as of December 31, 2014 has been restated to correct the misclassification. The correction results in reductions in common shares of beneficial interest and additional paid-in capital at December 31, 2014 of $1,000 and $51.9 million, respectively, from the previously reported amounts of $150,000 and $3,740.6 million, respectively.  The reclassification has no impact on the previously reported consolidated statements of comprehensive income, nor does it have any effect on the previously reported consolidated statements of cash flows.  In addition, the reclassification has no impact on the previously reported consolidated financial statements of the Operating Partnership.

Recently Issued Accounting Standards

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"), which supersedes nearly all existing revenue recognition guidance. The standard clarifies the required factors that an entity must consider when recognizing revenue. The standard also requires additional disclosures concerning contracts with customers, judgments concerning revenue recognition, and assets recognized for the costs to obtain or fulfill a contract. ASU 2014-09 is effective for the Company beginning January 1, 2018. The Company is evaluating the impact ASU 2014-09 will have on its financial position and results of operations.

In April 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs ("ASU 2015-03"). The standard requires the costs for issuing debt to appear on a balance sheet as a direct deduction from the debt's value. ASU 2015-03 is effective for the Company beginning January 1, 2016. The standard would be applied retrospectively. The Company does not anticipate that the adoption of ASU 2015-03 will have a material impact on its financial position or results of operations.

In February 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis (Topic 810) ("ASU 2015-02"). The standard requires that all entities re-evaluate and revise consolidation documentation for limited partnerships and similar legal entities. It makes changes to both the variable interest model and voting model. ASU 2015-02 is effective for the Company

15

beginning January 1, 2016. The standard allows for either a full retrospective or a modified retrospective approach to adoption. The Company is evaluating the impact ASU 2015-02 will have on its financial position and results of operations.

The amount of anti-dilutive options excluded from the computation of diluted income per common share for the three and nine months ended September 30, 2015 was 2,260,000 and 1,528,000, respectively, as compared to 1,183,000 and 850,000, respectively, for the same periods in 2014.

During the three and nine months ended September 30, 2015, 12,000 and 65,000 common shares, respectively, were issued upon the exercise of options. During the year ended December 31, 2014, 44,000 common shares were issued upon the exercise of options.

Share Repurchase

In August 2015, the Company’s Board of Trustees authorized a share repurchase plan under which the Company may purchase up to $250 million of the Company’s outstanding common shares. Purchases made pursuant to the program will be made in either the open market or in privately negotiated transactions from time to time as permitted by securities laws and other legal requirements.

During the three and nine months ended September 30, 2015, the Company purchased an aggregate of 2,125,000 common shares for $65.5 million as part of the share repurchase plan.

During the three and nine months ended September 30, 2015, the Company purchased an aggregate of 2,125,000 common shares for $65.5 million as part of the share repurchase plan. In connection with these repurchases, an equal number of common units were repurchased by the Operating Partnership from the Trust.

Note 6: Accounting for the Impairment or Disposal of Long-Lived Assets

Prior to the adoption of Accounting Standards Update (ASU) 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360), Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity ("ASU 2014-08") on January 1, 2014, the results of operations for all operating properties sold or held for sale during the reported periods were shown under discontinued operations on the consolidated statements of comprehensive income. Under

23

ASU 2014-08, operating properties that were sold or classified as held for sale before the adoption of ASU 2014-08 continue to be classified as discontinued operations. Accordingly, operating properties previously reported as discontinued operations will continue to be presented as discontinued operations on the consolidated statements of comprehensive income for all periods presented.

A summary of the results of operations for the properties classified as discontinued operations through the respective disposition dates is as follows (in thousands):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2015		2014		2015		2014
Revenues	$	—	$	9	$	—	$	4,728
Operating expenses	—		86		—		(2,226		)
Interest and other income	—		—		—		39
Interest expense	—		—		—		(557		)
Depreciation and amortization	—		—		—		—

Gain on property dispositions	—		38		—		46,292
Net income	$	—	$	133	$	—	$	48,276

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

Asset Impairment

The Company disposes of and anticipates the potential disposition of certain properties prior to the end of their remaining useful lives. There were no impairments recognized during the three months ended September 30, 2015. During the nine months ended September 30, 2015, the Company recognized $16.8 million in impairments, $13.4 million of which related to properties sold in the Company's Richmond/Hampton Roads reportable segment (see Note 5), $2.3 million of which related to the Company's Southeastern Pennsylvania reportable segment and $1.0 million of which related to the Company's Maryland reportable segment. The Company determined these impairments based on third party offer prices and quoted offer prices for comparable transactions which are Level 2 and Level 3 inputs, respectively, according to the fair value hierarchy established by the FASB in Topic 820, "Fair Value Measurements and Disclosures." The Company has evaluated each of its properties and land held for development and has determined that there were no additional valuation adjustments necessary at September 30, 2015.  There were no impairments recognized during the three or nine months ended September 30, 2014.

Note 7: Noncontrolling Interests of the Trust

Noncontrolling interests in the accompanying financial statements represent the interests of the common and preferred units in the Operating Partnership not held by the Trust. In addition, noncontrolling interests include third-party ownership interests in consolidated joint venture investments.

Common units

The common units outstanding have the same economic characteristics as common shares of the Trust. The 3,539,075 outstanding common units as of September 30, 2015 not held by the Trust share proportionately in the net income or loss and in any distributions of the Operating Partnership. The common units of the Operating Partnership not held by the Trust are redeemable at any time at the option of the holder. The Trust, as the sole general partner of the Operating Partnership, may at its option elect to settle the redemption in cash or through the exchange on a one-for-one basis of unregistered common shares of the Trust. The market value of the 3,539,075 outstanding common units based on the closing price of the common shares of the Trust at September 30, 2015 was $111.5 million.

Note 8: Limited Partners' Equity and Noncontrolling Interest of the Operating Partnership

Limited partners' equity in the accompanying financial statements represents the interests of the common and preferred units in the Operating Partnership not held by the Trust. The Operating Partnership's noncontrolling interest includes third-party ownership interests in consolidated joint venture investments.

24

Common units

The common units outstanding have the same economic characteristics as common shares of the Trust. The 3,539,075 outstanding common units as of September 30, 2015 not held by the Trust are the limited partners' equity - common units held by persons and entities other than the Trust. The common units of the Operating Partnership not held by the Trust are redeemable at any time at the option of the holder. The Trust, as the sole general partner of the Operating Partnership, may at its option elect to settle the redemption in cash or through the exchange on a one-for-one basis of unregistered common shares of the Trust. The market value of the 3,539,075 outstanding common units at September 30, 2015 based on the closing price of the common shares of the Trust at September 30, 2015 was $111.5 million.

Note 9: Noncontrolling Interest - Operating Partnership/Limited Partners' Equity - Preferred Units

As of September 30, 2015, the Company had outstanding the following cumulative preferred units of the Operating Partnership:

ISSUE	AMOUNT		UNITS	LIQUIDATION PREFERENCE	DIVIDEND RATE
	(in 000’s)
Series I-2	$	7,537	301	$25	6.25	%

The preferred units are putable at the holder's option at any time and are callable at the Operating Partnership's option after a stated period of time for cash.

Note 10: Indebtedness

In March 2015, the Company used proceeds from its unsecured credit facility together with available cash on hand to repay all $300 million of its 5.125% senior unsecured notes due March 2015.

In March 2015, the Company issued $400 million of 3.75% senior unsecured notes due 2025. The net proceeds from this issuance were used to repay borrowings under the Company's unsecured credit facility and for general corporate purposes.

In August 2015, the Company used proceeds from its unsecured credit facility to prepay without penalty a $105.8 million7.0% mortgage loan due February 2016.

Note 11: Disclosure of Fair Value of Financial Instruments

The following disclosure of estimated fair value was determined by management using available market information and appropriate valuation methodologies. However, considerable judgment is necessary to interpret market data and develop estimated fair value. Accordingly, the following estimates are not necessarily indicative of the amounts the Company could have realized on disposition of the financial instruments at September 30, 2015 and December 31, 2014. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.

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

The Company determines the fair value of its interest rate swaps by using the standard methodology of netting discounted future fixed cash payments with the discounted expected variable cash receipts. These variable cash receipts of interest rate swaps are based on expectations of future LIBOR interest rates (forward curves) estimated by observing market LIBOR interest rate curves. This is a Level 2 fair value calculation. Also, credit valuation adjustments are factored into the fair value calculations to account for potential nonperformance risk. These credit valuation adjustments were concluded to be not significant inputs for the fair value calculations for the periods presented. See Note 13 - Derivative Instruments.

The Company used a discounted cash flow model to determine the estimated fair value of its debt as of September 30, 2015.  This is a Level 3 fair value calculation. The inputs used in preparing the discounted cash flow model include actual maturity dates and scheduled cash flows as well as estimates for market value discount rates.  The Company updates the discounted cash flow model on a quarterly basis to reflect any changes in the Company's debt holdings and changes to discount rate assumptions.  

25

The following summarizes the fair value of the Company's mortgage loans and unsecured notes as of December 31, 2014 and September 30, 2015 (in thousands):

	Mortgage Loans				Unsecured Notes
	Carrying Value		Fair Value		Carrying Value		Fair Value
As of December 31, 2014	$	487,301	$	501,231	$	2,509,094	$	2,704,069
As of September 30, 2015	$	372,660	$	381,500	$	2,608,307	$	2,621,855

Note 12: Unconsolidated Joint Ventures

Liberty Washington, LP

During the three and nine months ended September 30, 2015, Liberty Washington LP (a joint venture in which the Company holds a 25% interest) recognized impairment charges, the Company's share of which was $3.9 million and $11.5 million, respectively. The impairment charges were related to the Company's Northern Virginia reportable segment and the Company's share was included in equity in (loss) earnings of unconsolidated joint ventures in the accompanying consolidated statements of comprehensive income. The Company determined these impairments based on third party offer prices. This is a Level 2 fair value calculation.

As of September 30, 2015, the joint venture was in default of a $46.4 million non-recourse mortgage loan related to certain properties within the joint venture in the Company's Northern Virginia reportable segment.

Comcast Innovation and Technology Center

The Company has entered into two joint ventures for the purpose of developing and owning the Comcast Innovation & Technology Center (the "Project") located on the 1800 block of Arch Street in Philadelphia, Pennsylvania. The 59-story building will include 1.3 million square feet of rentable office space and a 222-room Four Seasons Hotel. Completion of the first phase of the Project is anticipated to be in the third quarter of 2017. Project costs for the development of the Project, exclusive of tenant-funded interior improvements, are anticipated to be approximately $932 million. The Company's investment in the Project is expected to be approximately $185 million with 20% ownership interests in both joint ventures.

The two joint ventures have engaged the Company as the developer of the Project pursuant to a Development Agreement by which the Company agrees, in consideration for a development fee, to be responsible for all aspects of the development of the Project and to guarantee the timely lien-free completion of construction of the Project and the payment, subject to certain exceptions, of any cost overruns incurred in the development of the Project.

Liberty Venture I, LP

During the nine months ended September 30, 2015, Liberty Venture I, LP (a joint venture in which the Company holds a 25% interest) realized gross proceeds of $8.5 million from the sale of one property totaling 198,000 square feet in the Company's New Jersey reportable segment.

Note 13: Derivative Instruments

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

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

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

The Company holds an interest in three interest rate swap contracts (“Swaps”) that eliminate the impact of changes in interest rates on the payments required under variable rate mortgages. The Swaps had aggregate notional amounts of $102.0 million and $103.6 million at September 30, 2015 and December 31, 2014, respectively, and expire at various dates between 2018 and 2020.

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

The following table presents the location in the financial statements of the gains or losses recognized related to the Company’s cash flow hedges for the three and nine months ended September 30, 2015 and 2014:

	Three Months Ended						Nine Months Ended
	September 30, 2015			September 30, 2014			September 30, 2015			September 30, 2014
	(in thousands)
Amount of (loss) gain related to the effective portion recognized in other comprehensive (loss) income	$	(1,570	)	$	299		$	(2,592	)	$	(2,083	)
Amount of (loss) gain related to the effective portion subsequently reclassified to earnings	$	(350	)	$	(367	)	$	(1,053	)	$	(1,093	)
Amount of (loss) gain related to the ineffective portion	$	(51	)	$	13		$	(113	)	$	(42	)

The fair value of the Swaps in the amounts of $8.7 million and $8.5 million as of September 30, 2015 and December 31, 2014, respectively, is included in other liabilities in the accompanying consolidated balance sheets. The Company estimates that $1.2 million will be reclassified from accumulated other comprehensive loss as an increase to interest expense over the next 12 months.

The Company has agreements with its derivative counterparties that contain a provision whereby if the Company defaults on any of its indebtedness, including defaults where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default on its derivative obligations. If the Company were to breach any of the contractual provisions of the derivative contracts, it would be required to settle its obligations under the agreements at their termination value including accrued interest, which totaled approximately $8.8 million as of September 30, 2015.

Note 14: Commitments and Contingencies

Environmental Matters

Substantially all of the Company's 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 or obtained by predecessor owners prior to the sale of the property or land to the Company. 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.

Operating Ground Lease Agreements

Future minimum rental payments under the terms of all non-cancelable operating ground leases under which the Company is the lessee, as of September 30, 2015, were as follows (in thousands):

Year	Amount
2015	$	250
2016	998
2017	998
2018	998
2019	998
2020 and thereafter	8,756
Total	$	12,998

Operating ground lease expense for the three and nine months ended September 30, 2015 was $224,000 and $536,000 as compared to $114,000 and $289,000 for the same periods in 2014, respectively.

Legal Matters

From time to time, the Company is a party to a variety of legal proceedings, claims and assessments arising in the normal course of business. As of September 30, 2015 there were no legal proceedings, claims or assessments that the Company expects to have a material adverse effect on the Company’s business or financial statements.

Other

As of September 30, 2015, the Company had letter of credit obligations of $5.4 million. The Company believes that the likelihood is remote that there will be a draw upon these letter of credit obligations.

As of September 30, 2015, the Company had 27 buildings under development. These buildings are expected to contain, when completed, a total of 6.6 million square feet of leasable space and represent an anticipated aggregate investment of $643.8 million. At September 30, 2015, development in progress totaled $338.7 million. In addition, as of September 30, 2015, the Company had invested $12.0 million in deferred leasing costs related to these development buildings. In addition, the Company had a signed commitment for a build-to-suit development not yet commenced for an anticipated investment of $44.9 million.

As of September 30, 2015, the Company was committed to $30.7 million in improvements on certain buildings and land parcels.

As of September 30, 2015, the Company was committed to $51.3 million in future land purchases.

As of September 30, 2015, the Company was obligated to pay for tenant improvements not yet completed for a maximum of $36.2 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.

Note 15: Supplemental Disclosure to Consolidated Statements of Cash Flows

The following are supplemental disclosures to the consolidated statements of cash flows for the nine months ended September 30, 2015 and 2014 (amounts in thousands):

	2015			2014
Write-off of fully depreciated/amortized property and deferred costs	$	44,216		$	31,322
Write-off of depreciated/amortized property and deferred costs due to sale/demolition	$	95,277		$	132,707
Unrealized loss on cash flow hedge	$	(1,539	)	$	(990	)
Changes in accrued development capital expenditures	$	5,023		$	7,854
Increase in investments in and advances to unconsolidated joint ventures	$	—		$	(11,948	)

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

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Overview

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

The Company owns and operates industrial properties nationally and owns and operates office properties in a focused group of office markets. Additionally, the Company owns certain assets in the United Kingdom.

As of September 30, 2015, the Company owned and operated 489 industrial and 157 office properties (the “Wholly Owned Properties in Operation”) totaling 92.1 million square feet. In addition, as of September 30, 2015, the Company owned 27 properties under development, which when completed are expected to comprise 6.6 million square feet (the “Wholly Owned Properties under Development”) and 1,528 acres of developable land, substantially all of which is zoned for commercial use. Additionally, as of September 30, 2015, the Company had an ownership interest, through unconsolidated joint ventures, in 48 industrial and 34 office properties totaling 14.1 million square feet (the “JV Properties in Operation” and, together with the Wholly Owned Properties in Operation, the “Properties in Operation”), six properties under development, which when completed are expected to comprise 3.0 million square feet and a 222-room hotel (the "JV Properties under Development" and, collectively with the Wholly Owned Properties under Development, the "Properties under Development" and, collectively with the Properties in Operation, the "Properties") and 402 acres of developable land, substantially all of which is zoned for commercial use.

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

Due to long-term trends that the Company believes favor industrial properties and metro-office properties and indicate potential erosion in value of suburban office properties, the Company has increased its investment in industrial and metro-office properties and decreased its investment in suburban office properties. The short-term effect of these activities is a reduction in net cash from operating activities, as rental income related to the Company's industrial properties is less than that from the Company's suburban office properties, assuming similar amounts invested. The Company anticipates that over time it will realize the benefits of these activities, including a higher rate of rental growth and a lower level of lease transaction costs and other capital costs for industrial properties as opposed to suburban office properties.

The Company’s operating results depend primarily upon income from rental operations and are substantially influenced by rental demand for the Properties in Operation. During the three and nine months ended September 30, 2015, respectively, straight line rents on renewal and replacement leases were on average 8.1% and 4.9% higher than rents on expiring leases. The Company's

29

guidance for 2015 contemplated an increase of straight line rent on average of 2% to 3%. During the three and nine months ended September 30, 2015, the Company successfully leased 6.7 million and 22.2 million square feet, respectively, and, as of that date, attained occupancy of 93.2% for the Wholly Owned Properties in Operation and 93.6% for the JV Properties in Operation for a combined occupancy of 93.2% for the Properties in Operation. At December 31, 2014, occupancy for the Wholly Owned Properties in Operation was 93.1% and for the JV Properties in Operation was 92.2% for a combined occupancy for the Properties in Operation of 93.0%. The Company's guidance for 2015 contemplated an increase in average occupancy of 1% to 2%.

Wholly Owned Capital Activity

Acquisitions

During the three months ended September 30, 2015, the Company acquired a portfolio of three operating properties and 139 acres of developable land for a total purchase price of $86.6 million. These properties, which contain 921,000 square feet of leaseable space, were 100% occupied as of September 30, 2015. During the nine months ended September 30, 2015, the Company acquired four operating properties for a total purchase price of $123.4 million. This purchase price also includes 139 acres of developable land. These properties, which contain 1.3 million square feet of leasable space, were 69.2% occupied as of September 30, 2015.

Dispositions

During the three months ended September 30, 2015, the Company realized proceeds of $89.8 million from the sale of six properties totaling 448,000 square feet. During the nine months ended September 30, 2015, the Company realized gross proceeds of $248.1 million from the sale of 36 properties and 3.1 acres of land totaling 2.5 million square feet. Included in these dispositions, for the nine months ended September 30, 2015, the Company sold 22 properties and 3.1 acres of land for $110.3 million to a firm controlled by the brother of David L. Lingerfelt, a member of the Company's Board of Trustees. The price was determined after these properties were directly marketed to a select group of private equity investors with guidance as to the Company's valuation considerations. Mr. Lingerfelt does not have an ownership interest in the firm controlled by his brother and was excluded from board deliberations pertaining to this sale.

Development

During the three months ended September 30, 2015, the Company brought into service two Wholly Owned Properties under Development representing 272,000 square feet and a Total Investment of $40.9 million. During the nine months ended September 30, 2015, the Company brought into service 10 Wholly Owned Properties under Development representing 2.0 million square feet and a Total Investment of $175.6 million. During the three months ended September 30, 2015, the Company initiated eight Wholly Owned Properties under Development with a projected Total Investment of $323.1 million. During the nine months ended September 30, 2015, the Company initiated 12 Wholly Owned Properties under Development with a projected Total Investment of $357.3 million. As of September 30, 2015, the Company had 27 Wholly Owned Properties under Development with a projected Total Investment of $643.8 million.

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

Unconsolidated Joint Venture Capital Activity

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

Acquisitions/Dispositions

During the nine months ended September 30, 2015, an unconsolidated joint venture in which the Company held a 25% interest realized gross proceeds of $8.5 million for the sale of one property totaling 198,000 square feet. None of the unconsolidated joint ventures in which the Company held an interest acquired any operating properties or land parcels. Consistent with the Company's strategy, from time to time the Company may consider transferring assets to or purchasing assets from an unconsolidated joint venture in which the Company holds an interest.

30

Development

During the three months ended September 30, 2015, a joint venture in which the Company held a 25% interest began development on one property, which is expected to comprise, upon completion, 614,000 square feet and is expected to represent a Total Investment of $40.3 million. During the nine months ended September 30, 2015, a joint venture in which the Company held a 25% interest began development on two properties, which are expected to comprise, upon completion, 825,000 square feet and are expected to represent a Total Investment of $54.8 million. As of September 30, 2015, joint ventures in which the Company held an interest had six properties under development which are expected to comprise, upon completion, 3.0 million square feet and are expected to represent a Total Investment of $1.0 billion.

The most significant of these properties under development is the Comcast Innovation & Technology Center, which is expected to comprise, upon completion, 1.3 million square feet and a 222-room hotel and is expected to represent a Total Investment of approximately $932 million.

(1) Net rent represents the contractual rent per square foot at September 30, 2015 or 2014 for tenants in occupancy. Net rent does not include the tenant's obligation to pay property operating expenses and real estate taxes. If a tenant was within a free rent period its rent would equal zero for the purposes of this metric.

(2) Straight line rent and operating expense reimbursement represents the straight line rent including operating expense recoveries per square foot at September 30, 2015 or 2014 for tenants in occupancy.

(3) JV Properties in Operation represents the properties owned by unconsolidated joint ventures in which the Company had an interest during the respective periods. Unconsolidated joint ventures in which the Company holds an interest owned 82 properties as of September 30, 2015 and 2014.

Forward-Looking Statements

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

Critical Accounting Policies and Estimates

Refer to the Company’s Annual Report on Form 10-K for the year ended December 31, 2014 for a discussion of critical accounting policies which include capitalized costs, revenue recognition, allowance for doubtful accounts, impairment of real estate, intangibles, investments in unconsolidated joint ventures and derivative instruments and hedging activities. During the nine months ended September 30, 2015, there were no material changes to these policies.

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 three and nine months ended September 30, 2015 with the results of operations of the Company for the three and nine months ended September 30, 2014. As a result of the varying levels of development, acquisition and disposition activities by the Company in 2015 and 2014, 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 Three and Nine Months Ended September 30, 2015 to Three and Nine Months Ended September 30, 2014

Rental Revenue

Rental revenue was $145.0 million for the three months ended September 30, 2015 compared to $143.3 million for the same period in 2014. This increase of $1.7 million was primarily due to same store property rental revenue (increase of $2.6 million) and termination fees (increase of $1.7 million). These increases were partially offset by the net result of increased rental revenue related to acquisitions and completed development since July 1, 2014 and decreased rental revenue related to property dispositions for the same period.

32

Rental revenue was $441.0 million for the nine months ended September 30, 2015 compared to $421.6 million for the same period in 2014. This increase of $19.4 million was primarily due to same store property rental revenue (increase of $6.9 million) and termination fees (increase of $5.4 million). Also contributing to the increase was the net result of increased rental revenue from acquisitions and completed development since January 1, 2014 and decreased rental revenue from property dispositions for the same period.

Termination fees are fees that the Company agrees 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 and if a property is classified as discontinued operations, related termination fees are included in discontinued operations.

Operating Expense Reimbursement

Operating expense reimbursement was $54.0 million for the three months ended September 30, 2015 compared to $55.1 million for the same period in 2014. This decrease of $1.1 million was primarily due to an aggregate decrease of $1.3 million in rental property expense and real estate taxes. Occupancy results also impact these amounts as the ability to recover operating expenses corresponds to tenant occupancy. While average occupancy for the Company increased for the three months ended September 30, 2015 compared to the same period in 2014, average occupancy for suburban office properties decreased. Operating expenses for suburban office properties are historically higher than operating expenses for industrial properties.

Operating expense reimbursement was $168.4 million for the nine months ended September 30, 2015 compared to $167.3 million for the same period in 2014. This increase of $1.1 million was primarily due to the increase in average occupancy for the nine months ended September 30, 2015 compared to the same period in the prior year.

Rental Property Expense

Rental property expense was $31.5 million for the three months ended September 30, 2015 compared to $33.1 million for the same period in 2014. This decrease of $1.6 million was primarily due to the sale of suburban office and high finish flex properties partially offset by increased expenses resulting from primarily industrial acquisition and completed development properties. Rental property expense includes utilities, insurance, janitorial, landscaping, snow removal and other costs necessary to maintain a property.

Rental property expense was $99.0 million for the nine months ended September 30, 2015 compared to $103.7 million for the same period in 2014. This decrease of $4.7 million was primarily due to the sale of suburban office and high finish flex properties partially offset by increases resulting from primarily industrial acquisition and completed development properties. The decrease was also due to higher weather-related expenses during the nine months ended September 30, 2014 and reductions in certain one-time expense items.

Real Estate Taxes

Real estate taxes were $26.0 million for the three months ended September 30, 2015 compared to $25.6 million for the same period in 2014. This increase of $0.4 million was primarily due to real estate taxes for the same store group of properties (increase of $0.9 million) partially offset by a net decrease in real estate taxes from acquisitions, completed development and dispositions.

Real estate taxes were $78.6 million for the nine months ended September 30, 2015 compared to $75.8 million for the same period in 2014. This increase of $2.8 million was primarily due to a net increase in real estate taxes for the same store group of properties (increase of $2.0 million) as well as a net increase in real estate taxes from acquisitions, completed development and dispositions.

Segments

The Company evaluates the performance of the Wholly Owned Properties in Operation in terms of net operating income by reportable segment (see Note 5 to the Company’s financial statements for a reconciliation of this measure to income from continuing operations). The following table identifies changes to net operating income in reportable segments (dollars in thousands):

	Three Months Ended				Percentage Increase (Decrease)			Nine Months Ended				Percentage Increase (Decrease)

Total reportable segment net operating income	$	125,635	$	124,521	0.9	%		$	382,365	$	366,588	4.3	%

(1) The increase was primarily due to an increase in average gross investment in operating real estate.

(2) The increase was primarily due to an increase in occupancy and an increase in average gross investment in operating real estate.

(3) The decrease is primarily due to a decrease in occupancy and a decrease in average gross investment in operating real estate.

(4) The decrease was primarily due to a decrease in average gross investment in operating real estate.

Same Store

Property level operating income, exclusive of termination fees, for the Same Store properties is identified in the table below.

The Same Store results were affected by changes in occupancy and rental rates as detailed below for the respective periods as well as the decrease in the non-recovered portion of the snow removal costs and other weather-related expenses for the respective periods.

	Three Months Ended						Nine Months Ended
	September 30,						September 30,
	2015			2014			2015			2014
Average occupancy %	93.9		%	92.2		%	93.6		%	91.8		%
Average rental rate - cash basis (1)	$	6.54		$	6.60		$	6.55		$	6.60
Average rental rate - straight line rent and operating expense reimbursement (2)	$	9.27		$	9.22		$	9.23		$	9.21

(1) Represents the average contractual rent per square foot for the three and nine months ended September 30, 2015 or 2014 for tenants in occupancy in Same Store properties. Cash basis rent does not include the tenant's obligation to pay property operating expenses and real estate taxes. If a tenant was within a free rent period its rent would equal zero for purposes of this metric.

(2) Represents the average straight line rent including operating expense recoveries per square foot for the three and nine months ended September 30, 2015 or 2014 for tenants in occupancy in the Same Store properties.

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. In addition, Same Store property level operating income and Same Store cash basis property level operating income are considered by management to be more reliable indicators of the portfolio’s baseline performance. The Same Store properties consist of the 613 properties totaling approximately 82.3 million square feet owned on January 1, 2014. Properties that were acquired, or on which development was completed, during the year

34

ended December 31, 2014 and the nine months ended September 30, 2015 are excluded from the Same Store properties. Properties that were acquired, or on which development was completed, are included in Same Store when they have been purchased in the case of acquisitions, and placed into service in the case of completed development, prior to the beginning of the earliest period presented in the comparison. The 36 properties sold during the nine months ended September 30, 2015 and the 65 properties sold during 2014 are also excluded.

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 three and nine months ended September 30, 2015 and 2014. Same Store property level operating income and cash basis property level operating income are non-GAAP measures and do not represent income before gain on property dispositions, income taxes and equity in earnings of unconsolidated joint ventures because they do not reflect the consolidated operations of the Company. Investors should review Same Store results, along with NAREIT Funds from operations (see “Liquidity and Capital Resources” below), GAAP net income and cash flow from operating activities, investing activities and financing activities when considering the Company’s operating performance. Also set forth below is a reconciliation of Same Store property level operating income and cash basis property level operating income to net income (in thousands).

General and Administrative

General and administrative expenses increased to $15.6 million for the three months ended September 30, 2015 compared to $14.7 million for the three months ended September 30, 2014 and increased to $51.4 million for the nine months ended September 30, 2015 compared to $48.1 million for the nine months ended September 30, 2014. These increases were primarily due to increases in performance-based compensation, severance costs and general and administrative costs related to the construction of the Comcast Innovation & Technology Center partially offset by reductions in acquisition-related expenses. General and administrative expenses include salaries, wages and incentive compensation for general and administrative staff along with related costs, consulting, marketing, public company expenses, costs associated with the acquisition of properties and other general and administrative costs.

Depreciation and Amortization

Depreciation and amortization decreased to $55.7 million for the three months ended September 30, 2015 from $58.6 million for the three months ended September 30, 2014 and decreased to $171.3 million for the nine months ended September 30, 2015 from $173.2 million for the nine months ended September 30, 2014. These decreases were primarily due to a reduction in amortization of in-place lease intangibles.

Impairment - Real Estate Assets

Impairment - real estate assets increased to $16.8 million for the nine months ended September 30, 2015 compared to zero for the nine months ended September 30, 2014. This increase was due to impairments related to certain properties in the Company's Maryland and Richmond/Hampton Roads reportable segments. The properties related to the Richmond/Hampton Roads reportable segment were subsequently sold. There were no impairments to real estate assets for the three months ended September 30, 2015 or September 30, 2014.

Interest and Other Income

Interest and other income decreased to $5.0 million for the three months ended September 30, 2015 from $6.2 million for the three months ended September 30, 2014. This decrease was primarily related to a decrease in gains associated with a land development in the United Kingdom. Interest and other income increased to $17.9 million for the nine months ended September 30, 2015 from $11.8 million for the nine months ended September 30, 2014. This increase was primarily due to development fee income related to joint ventures for the Comcast Innovation and Technology Center and increases in gains associated with a land development in the United Kingdom.

Interest Expense

Interest expense decreased to $33.6 million for the three months ended September 30, 2015 from $38.0 million for the three months ended September 30, 2014 and decreased to $103.3 million for the nine months ended September 30, 2015 from $115.6 million for the nine months ended September 30, 2014.

The decrease for the three month periods was primarily due to a decrease in the average debt outstanding to $3,192.2 million for the three months ended September 30, 2015 compared to $3,206.7 million for the three months ended September 30, 2014 as well as a decrease in the weighted average interest rate to 4.6% for the three months ended September 30, 2015 compared to 4.9% for the three months ended September 30, 2014. The decrease was also due to an increase in capitalized interest, which was $4.6 million for the three months ended September 30, 2015 compared to $3.0 million for the same period in 2014.

The decrease for the nine month periods was primarily due to a decrease in the average debt outstanding to $3,142.2 million for the nine months ended September 30, 2015 compared to $3,235.8 million for the nine months ended September 30, 2014 as well as a decrease in the weighted average interest rate to 4.7% for the nine months ended September 30, 2015 compared to 5.0% for the nine months ended September 30, 2014. The decrease was also due to an increase in capitalized interest, which was $12.0 million for the nine months ended September 30, 2015 compared to $9.8 million for the same period in 2014. These changes were partially offset by the decrease in interest allocated to discontinued operations. There was no interest expense allocated to discontinued operations for the nine months ended September 30, 2015 compared to $557,000 for the nine months ended September 30, 2014.

36

Equity in (Loss) Earnings of Unconsolidated Joint Ventures

Equity in (loss) earnings of unconsolidated joint ventures decreased to a loss of $0.8 million for the three months ended September 30, 2015 compared to income of $1.6 million for the three months ended September 30, 2014 and decreased to income of $0.8 million for the nine months ended September 30, 2015 compared to income of $7.3 million for the nine months ended September 30, 2014. These decreases for the three and nine month periods were primarily due to impairment losses in an unconsolidated joint venture in the Company's Northern Virginia segment, the Company's share of which was $3.9 and $11.5 million for the three and nine months ended September 30, 2015, respectively. For the nine month periods this was partially offset by an increase in gains related to the sale of land leasehold interests by an unconsolidated joint venture in which the Company holds an interest. The Company's share of such gains was $4.8 million for the nine months ended September 30, 2015 compared to $2.7 million for the nine months ended September 30, 2014.

Other

Gain on property dispositions increased to $53.5 million for the three months ended September 30, 2015 compared to zero for the three months ended September 30, 2014 and increased to $57.0 million for the nine months ended September 30, 2015 from $1.9 million for the nine months ended September 30, 2014. Income from discontinued operations was zero for the three and nine months ended September 30, 2015 compared to $133,000 and $48.3 million for the three and nine months ended September 30, 2014, respectively. Year over year changes primarily resulted from aggregate gains and losses on sales included in gain (loss) on property dispositions or discontinued operations which totaled gains of $53.5 million and $57.0 million for the three and nine months ended September 30, 2015 compared to a gains of $18,000 and $48.2 million for the three and nine months ended September 30, 2014, respectively.

As a result of the foregoing, the Company’s net income increased to $93.7 million for the three months ended September 30, 2015 from $35.5 million for the three months ended September 30, 2014 and increased to $162.1 million for the nine months ended September 30, 2015 from $139.7 million for the nine months ended September 30, 2014.

Liquidity and Capital Resources

Overview

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

Activity

As of September 30, 2015, the Company had cash and cash equivalents of $63.6 million, including $14.9 million in restricted cash.

Net cash provided by operating activities increased to $299.7 million for the nine months ended September 30, 2015 from $250.3 million for the nine months ended September 30, 2014. This $49.4 million increase was primarily due to an increase in Same Store operating activities and an increase in net operating activities related to acquisitions, dispositions and completed development. In addition, termination fees for the nine months ended September 30, 2015 and 2014 were $6.8 million and $1.3 million, respectively. Net cash flow provided by operating activities is the primary source of liquidity to fund distributions to shareholders and for recurring capital expenditures and leasing transaction costs for the Company’s Wholly Owned Properties in Operation.

Net cash used in investing activities was $188.6 million for the nine months ended September 30, 2015 compared to $130.5 million for the nine months ended September 30, 2014. This $58.1 million change primarily resulted from a decrease in net proceeds from the disposition of properties and land associated with the close of the second settlement of a multi-market portfolio sale in 2014. This amount was partially offset by a decrease in the investment in development properties net of an increase in investment in land. Additionally, cash used to fund the Company's investment in the Comcast Innovation and Technology Center, an unconsolidated joint venture, has increased.

Net cash used in financing activities decreased to $130.2 million for the nine months ended September 30, 2015 compared to $243.4 million for the nine months ended September 30, 2014. This $113.2 million decrease in cash used was primarily due to net debt activity partially offset by common share repurchases during 2015. Financing activities include proceeds from the issuance of equity and debt, debt repayments, equity repurchases and distributions.

37

In March 2015, the Company used proceeds from its unsecured credit facility together with available cash on hand to repay all $300 million of its 5.125% senior unsecured notes due March 2015.

In March 2015, the Company issued $400 million of 3.75% senior unsecured notes due 2025. The net proceeds from this issuance were used to repay borrowings under the Company's unsecured credit facility and for general corporate purposes.

In August 2015, the Company used proceeds from its unsecured credit facility to prepay without penalty a $105.8 million 7.0% mortgage loan due February 2016.

In August and September 2015, the Company purchased an aggregate of 2,125,000 common shares of the Company for $65.5 million as part of a share repurchase plan.

The Company funds its development activities, including its obligations associated with its joint venture development activity, and acquisitions with long-term capital sources and proceeds from the disposition of properties. When appropriate the Company also funds such activities with available capacity under its $800 million credit facility (the "Credit Facility"). The interest rate on borrowings under the Credit Facility fluctuates based upon ratings from Moody’s Investors Service, Inc., Standard and Poor’s Ratings Group and Fitch, Inc. Based on the Company’s existing ratings, the interest rate for borrowings under the Credit Facility at September 30, 2015 was LIBOR plus 105 basis points. There is also a 20 basis point annual facility fee on the current borrowing capacity. The credit facility contains a competitive bid option, whereby participating lenders bid on the interest rate to be charged. This feature is available for up to 50% of the amount of the facility.

The Company uses debt financing to lower its overall cost of capital in an attempt to increase the return to shareholders. The Company staggers its debt maturities and maintains debt levels it considers to be prudent. In determining its debt levels, the Company considers various financial measures including the debt to gross assets ratio and the fixed charge coverage ratio. As of September 30, 2015, the Company’s debt to gross assets ratio was 41.4% and for the nine months ended September 30, 2015, the fixed charge coverage ratio was 3.6x. Debt to gross assets equals total long-term debt and borrowings under the Credit Facility divided by total assets plus accumulated depreciation. The fixed charge coverage ratio equals income from continuing operations before property dispositions plus interest expense, depreciation and amortization (including the Company's pro rata share of depreciation and amortization related to unconsolidated joint ventures) and impairment - real estate assets (including the Company's pro rata share of impairment - real estate assets related to unconsolidated joint ventures), divided by interest expense, including capitalized interest, plus distributions on preferred units.

As of September 30, 2015, $372.7 million in mortgage loans and $2,608.3 million in unsecured notes were outstanding with a weighted average interest rate of 4.74%. The interest rates on $2,965.0 million of mortgage loans and unsecured notes are fixed (including $102.0 million fixed via a swap arrangement - see Note 13 to the Company's financial statements) and range from 3.0% to 7.5%. The weighted average remaining term for the mortgage loans and unsecured notes is 5.9 years.

The scheduled principal amortization and maturities of the Company’s mortgage loans, unsecured notes and the Credit Facility and the related weighted average interest rates as of September 30, 2015 are as follows (in thousands, except percentages):

	MORTGAGES										WEIGHTED AVERAGE INTEREST RATE

Calculation of Funds from Operations

The National Association of Real Estate Investment Trusts (“NAREIT”) has issued a standard definition for NAREIT Funds from operations (as defined below). The SEC has agreed to the disclosure of this non-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 NAREIT Funds from operations is helpful to investors and management as it is a measure of the Company’s operating performance that excludes depreciation and amortization and gains and losses from operating property dispositions. As a result, year over year comparison of NAREIT Funds from operations reflects the impact on operations from trends in occupancy rates, rental rates, operating costs, development activities, general and administrative expenses, and interest costs, providing perspective not immediately apparent from net income. In addition, management believes that NAREIT Funds from operations provides useful information to the investment community about the Company’s financial performance when compared to other REITs since NAREIT Funds from operations is generally recognized as the standard for reporting the operating performance of a REIT. NAREIT Funds from operations available to common shareholders is defined by NAREIT as net income (computed in accordance with generally accepted accounting principles (“GAAP”)), excluding gains (or losses) from sales of property, plus depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. NAREIT Funds from operations available to common shareholders does not represent net income or cash flows from operations as defined by GAAP and does not necessarily indicate that cash flows will be sufficient to fund cash needs. It should not be considered as an alternative to net income as an indicator of the Company’s operating performance or to cash flows as a measure of liquidity. NAREIT Funds from operations available to common shareholders also does not represent cash flows generated from operating, investing or financing activities as defined by GAAP.

Inflation

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