Liberty Property Trust

Notes to Condensed Consolidated Financial Statements (Unaudited)

March 31, 2010

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 Liberty Property Limited Partnership (the “Operating Partnership” and, collectively 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 96.6% of the common equity of the Operating Partnership at March 31, 2010. 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, Midwestern and Southwestern United States and the United Kingdom. See a description of the Company’s markets in Note 2 to the Company’s financial statements.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of the Trust and its subsidiaries, including the Operating Partnership, 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 Trust and the Operating Partnership for the year ended December 31, 2009. 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. Certain amounts from prior periods have been reclassified to conform to the current period presentation.

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):


	For the Three Months Ended March 31, 2010						For the Three Months Ended March 31, 2009
			Weighted						Weighted
			Average						Average
	Income		Shares				Income		Shares
	(Numerator)		(Denominator)		Per Share		(Numerator)		(Denominator)		Per Share
Basic income from continuing operations
Income from continuing operations net of noncontrolling interest	$	26,784		112,341	$	0.24	$	27,194		100,681	$	0.27

Dilutive shares for long-term compensation plans		—		614				—		279


Diluted income from continuing operations
Income from continuing operations net of noncontrolling interest and assumed conversions		26,784		112,955	$	0.24		27,194		100,960	$	0.27


Basic income from discontinued operations
Discontinued operations net of noncontrolling interest		2,767		112,341	$	0.02		695		100,681	$	0.01

Dilutive shares for long-term compensation plans		—		614				—		279


Diluted income from discontinued operations
Discontinued operations net of noncontrolling interest		2,767		112,955	$	0.02		695		100,960	$	0.01


Basic income per common share
Net income available to common shareholders		29,551		112,341	$	0.26		27,889		100,681	$	0.28

Dilutive shares for long-term compensation plans		—		614				—		279


Diluted income per common share
Net income available to common shareholders and assumed conversions	$	29,551		112,955	$	0.26	$	27,889		100,960	$	0.28

Dilutive shares for long-term compensation plans represent the vested and unvested Common Shares outstanding during the year as well as the dilutive effect of outstanding options. The amounts of anti-dilutive options that were excluded from the computation of diluted income per common share for the three months ended March 31, 2010 and 2009 were 1,010,000 and 3,342,000, respectively.

During the three months ended March 31, 2010, 15,000 common shares were issued upon the exercise of options.

Foreign Currency Translation

The functional currency of the Company’s United Kingdom operations is pounds sterling. The Company translates the financial statements for the United Kingdom operations into US dollars. Gains and losses resulting from this translation do not impact the results of operations and are included in accumulated other comprehensive (loss) income as a separate component of shareholders’ equity. A proportionate amount of gain or loss is allocated to noncontrolling interest-common units. Accumulated other comprehensive (loss) income consists solely of the foreign currency translation adjustments described above. Other comprehensive loss for the three months ended March 31, 2010 was $4.6 million as compared to $1.3 million for the same period in 2009. Upon sale or upon complete or substantially complete liquidation of the Company’s foreign investment, the gain or loss on the sale will include the cumulative translation adjustments that have been previously recorded in accumulated other comprehensive (loss) income and noncontrolling interest-common units.

Note 2: Segment Information

The Company operates its portfolio of properties primarily throughout the Mid-Atlantic, Southeastern, Midwestern and Southwestern United States. Additionally, the Company owns certain assets in the United Kingdom. The Company reviews the performance of the portfolio on a geographical basis. As such, the following regions are considered the Company’s reportable segments:


Reportable Segments		Markets

Northeast		Southeastern PA; Lehigh/Central PA; New Jersey
Midwest		Minnesota; Milwaukee; Chicago
Mid-Atlantic		Maryland; Carolinas; Richmond; Virginia Beach
South		Jacksonville; Orlando; Boca Raton; Tampa; Texas; Arizona
Philadelphia/D.C.		Philadelphia; Northern Virginia/Washington, D.C.
United Kingdom		County of Kent; West Midlands

The Company’s reportable segments are distinct business units which are each managed separately in order to concentrate market knowledge within a geographic area. Within these reportable segments, the Company derives its revenues from its two product types: industrial properties and office properties.

The Company evaluates performance of the reportable segments based on property level operating income, which is calculated as rental revenue and operating expense reimbursement less rental property expenses and real estate taxes. The accounting policies of the reportable segments are the same as those for the Company on a consolidated basis.

The operating information by segment is as follows (in thousands):

Note 3: Accounting for the Impairment or Disposal of Long-Lived Assets

The operating results and gain/(loss) on disposition of real estate for properties sold and held for sale are reflected in the condensed consolidated statements of operations as discontinued operations. Prior period financial statements have been adjusted for discontinued operations. The proceeds from dispositions of operating properties with no continuing involvement for the three months ended March 31, 2010 were $6.4 million as compared to $34.8 million for the same period in 2009.

Below is a summary of the results of operations for the properties held for sale and disposed of through the respective disposition dates (in thousands):


	Three Months Ended
	March 31, 2010			March 31, 2009

Revenues	$	125		$	5,038
Operating expenses		(90	)		(1,978	)
Interest expense		(13	)		(1,482	)
Depreciation and amortization		(20	)		(1,055	)

Income before property dispositions	$	2		$	523

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

Asset Impairment

During the three months ended March 31, 2010, the Company did not recognize any impairments. During the three months ended March 31, 2009, the Company recognized impairments of $693,000, of which $89,000 was related to a portfolio of properties in the Mid-Atlantic segment, $491,000 was related to a property in the Midwest segment and $113,000 was related to land in the Northeast segment.

For the three months ended March 31, 2009, $89,000 in impairment related to properties sold was included in the caption discontinued operations in the Company’s statement of operations and $604,000 in impairment was included in the caption gain (loss) on property dispositions in the Company’s statement of operations. The Company determined these impairments through a comparison of the aggregate future cash flows (including quoted offer prices) 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 March 31, 2010.

Note 4: Noncontrolling interests

Noncontrolling interests in the accompanying financial statements represent the interests of the common and preferred units in Liberty Property Limited 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 as of March 31, 2010 have the same economic characteristics as common shares of the Trust. The 3,943,224 outstanding common units 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 with unregistered common shares of the Trust. The market value of the 3,943,224 outstanding common units based on the closing price of the shares of the Company at March 31, 2010 was $133.8 million.

Preferred units

The Company has outstanding the following cumulative redeemable preferred units of the Operating Partnership (the “Preferred Units”):


					Liquidation		Dividend			Redeemable
Issue	Amount		Units		Preference		Rate			As of		Exchangeable after

Note 5: 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 March 31, 2010 and December 31, 2009. 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, dividends and distributions payable and other liabilities are reasonable estimates of fair value because of the short-term nature of these instruments. The fair value of the Company’s long-term debt was less than the aggregate carrying value by approximately $110.2 million and $33.5 million at March 31, 2010 and December 31, 2009, respectively. The fair value of the Company’s long-term debt is estimated using actual trading prices (where available) and using discounted cash flow analysis based on the borrowing rates currently available to the Company for loans with similar terms and maturities where actual trading prices are not available.

Disclosure about fair value of financial instruments is based on pertinent information available to management as of March 31, 2010 and December 31, 2009. Although as of the date of this report, management is not aware of any factors that would significantly affect the fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since March 31, 2010 and current estimates of fair value may differ significantly from the amounts presented herein.

Note 6: Recently Issued Accounting Standards

Beginning with the first quarter of 2010, the Company is required to conduct an ongoing assessment to determine whether each entity in which it has an equity interest is a variable interest entity that should be consolidated if certain qualitative factors indicate that the Company has the controlling interest. This accounting change is required to be retroactively applied for all periods presented. The adoption of the requirement did not have a material impact on the Company’s financial statements.

Note 7: Supplemental Disclosure to Statements of Cash Flows

The following are supplemental disclosures to the statements of cash flows for the three months ended March 31, 2010 and 2009 (amounts in thousands):


Non-cash activity	2010		2009
Write-off of fully depreciated property and deferred costs	$	5,518	$	881

Note 8: Subsequent Events

In April 2010, the Company used proceeds from its Credit Facility to repay $119.3 million principal value of mortgage loans. The weighted average interest rate of these loans as of March 31, 2010 was 7.3%. The mortgages encumbered certain of the Company’s operating properties with a net book value of $216.8 million. The Company incurred a $1.2 million prepayment penalty and wrote off $822,000 in deferred financing costs in conjunction with the prepayment of these loans.

Note 1: Organization and Basis of Presentation

Organization

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of the Operating Partnership and its subsidiaries 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 Trust and the Operating Partnership for the year ended December 31, 2009. 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. Certain amounts from prior periods have been reclassified to conform to the current period presentation.

Income per Common Unit

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

Dilutive units for long-term compensation plans represent the vested and unvested Common Units outstanding during the year as well as the dilutive effect of outstanding options. The amounts of anti-dilutive options that were excluded from the computation of diluted income per common share for the three months ended March 31, 2010 and 2009 were 1,010,000 and 3,342,000, respectively.

During the three months ended March 31, 2010, 15,000 common units were issued upon the exercise of options.

Foreign Currency Translation

The functional currency of the Company’s United Kingdom operations is pounds sterling. The Company translates the financial statements for the United Kingdom operations into US dollars. Gains and losses resulting from this translation do not impact the results of operations and are included in general partner’s equity — common units and limited partners’ equity-common units. Other comprehensive loss for the three months ended March 31, 2010 was $4.6 million as compared to $1.3 million for the same period in 2009. Upon sale or upon complete or substantially complete liquidation of a foreign investment, the gain or loss on the sale will include the cumulative translation adjustments that have been previously recorded in general partner’s equity-common units and limited partners’ equity — common units.

Note 4: Limited partners’ equity

Common units

General and limited partners’ equity — common units relates to limited partnership interests of the Operating Partnership issued in connection with the formation of the Company and certain subsequent acquisitions. The common units outstanding as of March 31, 2010 have the same economic characteristics as common shares of the Trust. The 3,943,224 outstanding common units are the limited partners’ equity — common units held by persons and entities other than Liberty Property Trust, the general partner of Liberty Property Limited Partnership, which holds a number of common units equal to the number of outstanding common shares of beneficial interest. Both the common units held by Liberty Property Trust and the common units held by persons and entities other than Liberty Property Trust are counted in the weighted average number of common units outstanding during any given period. The 3,943,224 outstanding 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 market value of the 3,943,224 outstanding common units at March 31, 2010 based on the closing price of the shares of the Company at March 31, 2010 was $133.8 million.

Preferred units

The Company has outstanding the following cumulative redeemable preferred units of the Operating Partnership (the “Preferred Units”):


					Liquidation		Dividend			Redeemable
Issue	Amount		Units		Preference		Rate			As of		Exchangeable after
	(in 000’s)

Series B	$	95,000		3,800	$	25		7.45	%		8/31/09	8/31/13 into Series B Cumulative Redeemable Preferred Shares of the Trust

Series E	$	20,000		400	$	50		7.00	%		6/16/10	6/16/15 into Series E Cumulative Redeemable Preferred Shares of the Trust

Series F	$	50,000		1,000	$	50		6.65	%		6/30/10	12/12/15 into Series F Cumulative Redeemable Preferred Shares of the Trust

Series G	$	27,000		540	$	50		6.70	%		12/15/11	12/15/16 into Series G Cumulative Redeemable Preferred Shares of the Trust

Series H	$	100,000		4,000	$	25		7.40	%		8/21/12	8/21/17 into Series H Cumulative Redeemable Preferred Shares of the Trust

The Preferred Units are callable at the Operating Partnership’s option after a stated period of time. The Trust as the sole general partner of the Operating Partnership may at its option elect to settle the redemption for cash or through the exchange on a one-on-one basis with unregistered preferred shares of the Trust.

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 operates primarily in the Mid-Atlantic, Southeastern, Midwestern and Southwestern United States. Additionally, the Company owns certain assets in the United Kingdom.

As of March 31, 2010, the Company owned and operated 347 industrial and 291 office properties (the “Wholly Owned Properties in Operation”) totaling 64.4 million square feet. In addition, as of March 31, 2010, the Company owned two properties under development, which when completed are expected to comprise 286,000 square feet (the “Wholly Owned Properties under Development”), and 1,355 acres of developable land, substantially all of which is zoned for commercial use. Additionally, as of March 31, 2010, the Company had an ownership interest, through unconsolidated joint ventures, in 47 industrial and 49 office properties totaling 13.8 million square feet (the “JV Properties in Operation” and, together with the Wholly Owned Properties in Operation, the “Properties in Operation”), and two properties under development, which when completed are expected to comprise 640,000 square feet (the “JV Properties under Development” and, together with the Wholly Owned Properties under Development, the “Properties under Development”). The Company also has an ownership interest through unconsolidated joint ventures in 630 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 increasing rental rates and controlling costs. The Company pursues development opportunities that it believes will create value and yield acceptable returns. The Company also acquires properties that it believes will create long-term value, and disposes of properties that no longer fit within the Company’s strategic objectives or in situations where it can optimize cash proceeds. The Company’s operating results depend primarily upon income from rental operations and are substantially influenced by rental demand for the Properties in Operation. Continued weakness in the economy has had a negative impact on the Company’s business. Although credit market conditions have somewhat improved for the Company, continued general credit constraints in the economy, as well as persistent high levels of unemployment, present challenges both with respect to the pricing of commercial real estate and demand for the Company’s products.

Consistent with the current reduced level of economic growth in the United States, rental demand for the Properties in Operation has remained weak for the three months ended March 31, 2010 even though improved when compared to the three months ended March 31, 2009. Despite this weakness, the Company successfully leased 3.8 million square feet in its Properties in Operation during the three months ended March 31, 2010 and attained occupancy of 88.7% for the Wholly Owned Properties in Operation and 86.0% for the JV Properties in Operation for a combined occupancy of 88.2% for the Properties in Operation, all as of that date. At December 31, 2009, occupancy for the Wholly Owned Properties in Operation was 89.5% and for the JV Properties in Operation was 87.7% for a combined occupancy for the Properties in Operation of 89.2%. The Company believes that straight line rents on renewal and replacement leases for 2010 will on average be 10% to 15% lower than rents on expiring leases. Furthermore, the Company believes that average occupancy for its Properties in Operation will not increase or decrease by more than 1% for 2010 compared to 2009.

WHOLLY OWNED CAPITAL ACTIVITY

Acquisitions

The Company did not acquire any operating properties during the three months ended March 31, 2010. For 2010, the Company anticipates that wholly owned property acquisitions will range from no acquisitions to acquisitions of up to $100 million.

Dispositions

Disposition activity allows the Company to, among other things, (1) reduce its holdings in certain markets and product types within a market; (2) lower the average age of the portfolio; (3) optimize the cash proceeds from the sale of certain assets; and (4) obtain funds for investment activities. During the three months ended March 31, 2010, the Company realized proceeds of $6.4 million from the sale of two operating properties representing 78,000 square feet. For 2010, the Company believes it will realize proceeds of approximately $75 million to $125 million from the sale of operating properties.

Development

During the three months ended March 31, 2010, the Company brought into service one Wholly Owned Property under Development representing 95,000 square feet and a Total Investment, as defined below, of $24.8 million, and did not initiate any development. As of March 31, 2010, the projected Total Investment of the Wholly Owned Properties under Development was $58.2 million. For 2010, the Company expects to bring into service operating properties representing between $75 million and $100 million of Total Investment. Although the Company continues to pursue development opportunities, current market conditions are not generally favorable for speculative development. Any development starts for 2010 likely will be substantially pre-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.

JOINT VENTURE CAPITAL ACTIVITY

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

Acquisitions

During the three months ended March 31, 2010, none of the unconsolidated joint ventures in which the Company held an interest acquired any properties. For 2010, the Company believes that none of the unconsolidated joint ventures in which the Company holds an interest will acquire any properties.

Dispositions

During the three months ended March 31, 2010, none of the unconsolidated joint ventures in which the Company held an interest disposed of any properties. For 2010, the Company does not anticipate that any unconsolidated joint ventures in which it holds an interest will dispose of any operating properties.

Development

During the three months ended March 31, 2010, no unconsolidated joint ventures in which the Company held an interest brought any properties into service. As of March 31, 2010, the projected Total Investment of JV Properties under Development was $160.1 million. For 2010, the Company expects unconsolidated joint ventures in which it holds an interest to bring into service between $125 million and $175 million of Total Investment in operating properties.

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, 2009 for a discussion of critical accounting policies which include capitalized costs, revenue recognition, allowance for doubtful accounts, impairment of real estate, intangibles and investments in unconsolidated joint ventures. During the three months ended March 31, 2010, 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 months ended March 31, 2010 with the results of operations of the Company for the three months ended March 31, 2009. As a result of the varying levels of development, acquisition and disposition activities by the Company in 2010 and 2009, 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 condensed consolidated financial statements and notes included elsewhere in this report.

Comparison of Three Months Ended March 31, 2010 to Three Months Ended March 31, 2009

Overview

The Company’s average gross investment in operating real estate owned for the three months ended March 31, 2010 increased to $5,115.2 million from $4,920.3 million for the three months ended March 31, 2009. This increase in operating real estate resulted in increases in rental revenue, operating expense reimbursement, rental property expenses, real estate taxes and depreciation and amortization expense.

Total operating revenue increased to $189.2 million for the three months ended March 31, 2010 from $185.3 million for the three months ended March 31, 2009. The $3.9 million increase was primarily due to the increase in investment in operating real estate and an increase in “Termination Fees,” which totaled $1.8 million for the three months ended March 31, 2010 as compared to $0.3 million for the same period in 2009. 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 sold, related termination fees are included in discontinued operations.

Segments

The Company evaluates the performance of the Wholly Owned Properties in Operation in terms of property level operating income by reportable segment (see Note 2 to the Company’s financial statements for a reconciliation of this measure to net income). The following table identifies changes in reportable segments (dollars in thousands):

Property Level Operating Income:

Total property level operating income	$	125,972	$	124,985		0.8	%


(1)		The change was primarily due to an increase in average gross investment in operating real estate and an increase in rental rates. This increase was partially offset by a decrease in occupancy in 2010.

(2)		The change was primarily due to a decrease in occupancy. This decrease was partially offset by an increase in average gross investment in operating real estate and an increase in rental rates in 2010.

(3)		The change was primarily due to an increase in average gross investment in operating real estate, an increase in occupancy, and an increase in rental rates.

Same Store

Property level operating income, exclusive of Termination Fees, for the Same Store properties decreased to $118.9 million for the three months ended March 31, 2010 from $123.4 million for the three months ended March 31, 2009, on a straight line basis (which recognizes rental revenue evenly over the life of the lease), and decreased to $116.9 million for the three months ended March 31, 2010 from $119.7 million for the three months ended March 31, 2009 on a cash basis. These decreases of 3.6% and 2.3%, respectively, are primarily due to a decrease in occupancy.

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 and Same Store cash basis 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 623 properties totaling approximately 61.4 million square feet owned on January 1, 2009, excluding properties sold through March 31, 2010.

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 months ended March 31, 2010 and 2009. Same Store property level operating income and cash basis property level operating income are non-GAAP measures and do not represent income before 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 Funds from operations (see “Liquidity and Capital Resources” section), 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 decreased to $14.9 million for the three months ended March 31, 2010 compared to $15.6 million for the three months ended March 31, 2009. The decrease was primarily due to a decrease in expenses related to the Company’s Long Term Incentive compensation plan, or LTI. LTI expenses were $3.8 million for the three months ended March 31, 2010 compared to $5.4 million for the same period in 2009. This decrease was partially offset by increases in other one-time miscellaneous general and administrative expenses.

Depreciation and Amortization

Depreciation and amortization increased to $43.0 million for the three months ended March 31, 2010 from $42.6 million for the three months ended March 31, 2009. The increase was primarily due to the increased investment in operating real estate.

Interest Expense

Interest expense increased to $38.6 million for the three months ended March 31, 2010 from $37.2 million for the three months ended March 31, 2009. This increase was primarily related to a decrease in interest capitalized due to a decrease in development activity. The effect of the decrease in interest capitalized was partially offset by a decrease in interest expense associated with the decrease in the average debt outstanding to $2,403.7 million for the three months ended March 31, 2010 from $2,579.2 million for the three months ended March 31, 2009. The weighted average interest rate remained relatively unchanged at 6.3%.

Interest expense allocated to discontinued operations for the three months ended March 31, 2010 and 2009 was $13,000 and $1.5 million, respectively. This decrease was due to the decrease in the level of dispositions in 2010 compared to 2009.

Other

Gain (loss) on property dispositions increased to a gain of $0.8 million for the three months ended March 31, 2010 from a loss of $0.3 million for the three months ended March 31, 2009. The increase was primarily due to impairments recognized on certain of the Company’s properties in 2009 in connection with sales activities.

During the three months ended March 31, 2009, the Company purchased $11.4 million principal amount of its 7.75% April 2009 senior unsecured notes and $6.9 million of its 8.50% August 2010 senior unsecured notes. These notes were purchased at an aggregate $0.5 million discount. This discount is included in net income as a debt extinguishment gain. There were no similar transactions during the three months ended March 31, 2010.

Income from discontinued operations increased to $2.9 million for the three months ended March 31, 2010 from $0.7 million for the three months ended March 31, 2009. This increase was due to an increase in gains recognized on sales which were $2.9 million for the three months ended March 31, 2010 compared to $0.2 million for the three months ended March 31, 2009, respectively.

As a result of the foregoing, the Company’s net income increased to $35.8 million for the three months ended March 31, 2010 from $33.8 million for the three months ended March 31, 2009.

Liquidity and Capital Resources

Overview

The Company has historically accessed capital primarily from the public unsecured debt markets and the equity markets. The uncertainty in the global credit markets that existed in early 2009 has eased considerably for issuers such as the Company. The Company believes that its traditional access to capital through the unsecured debt market is currently available. Additionally, the Company’s sources of capital include proceeds from the disposition of properties, equity contributions from joint venture partners and net cash provided by operating activities. The Company also expects to incur variable rate debt, including borrowings under the Company’s credit facility, from time to time.

Activity

As of March 31, 2010, the Company had cash and cash equivalents of $179.7 million, including $38.1 million in restricted cash.

Net cash flow provided by operating activities decreased to $63.4 million for the three months ended March 31, 2010 from $105.0 million for the three months ended March 31, 2009. This $41.6 million decrease was primarily due to a decrease in operating activities and fluctuations in operating assets and liabilities during the respective periods. The decrease in operating activities is due to a decrease in same store performance. 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. To date during 2010 the performance of the Company’s business is consistent with its expectations. The Company anticipates increases in occupancy during the second half of 2010. However, if the anticipated increase in occupancy does not occur, the Company will experience additional demands on its capital resources.

Net cash provided by investing activities was $7.7 million for the three months ended March 31, 2010 compared to $1.5 million for the three months ended March 31, 2009. This $6.2 million increase primarily resulted from net proceeds received from a grant receivable and an escrow in 2010. There was no similar activity in 2009. Net cash provided by investing activities also increased due to the reduction of expenditures on the Company’s development pipeline. Offsetting these increases was a decrease in net proceeds from the disposition of properties and land.

Net cash used in financing activities was $164.3 million for the three months ended March 31, 2010 compared to net cash provided by financing activities of $14.1 million for the three months ended March 31, 2009. This $178.4 million change was primarily due to the net proceeds received in 2009 from the issuance of shares pursuant to the Company’s continuous equity offering program. Additionally during 2010 the Company repaid its credit facility in the amount of $105 million with cash on hand. Net cash provided by or used in financing activities includes proceeds from the issuance of equity and debt, net of debt repayments, equity repurchases and shareholder distributions. 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 and proceeds from the disposition of properties. For the three months ended March 31, 2010, a portion of these activities were funded through a $600 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. (“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 Credit Facility is 65 basis points over LIBOR. The Company has exercised its one year renewal option and the Credit Facility now expires in January 2011. The Company is currently in negotiations for a credit facility to replace the expiring Credit Facility. In light of the anticipated demands of the Company’s capital plan, the Company expects to reduce the amount of credit facility to approximately $400 million to $500 million. A closing on the replacement credit facility is expected to take place in the third quarter of 2010. Although still in negotiation, the Company anticipates that the interest rate on borrowings under the replacement credit facility will be higher than the interest rate on the expiring Credit Facility. Similar facilities that other borrowers have recently obtained have required rates equal to 200-300 basis points over LIBOR.

Additionally, the Company has entered into an agreement to fund its planned improvements for the Kings Hill Phase 2 land development project. At March 31, 2010, the Company hadn’t drawn any of a £7 million revolving credit facility. The facility expires on November 22, 2011.

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 March 31, 2010 the Company’s debt to gross assets ratio was 38.6% and for the three months ended March 31, 2010 the fixed charge coverage ratio was 2.6x. Debt to gross assets equals total long-term debt, 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, including operating activity from discontinued operations, plus interest expense and depreciation and amortization, divided by interest expense, including capitalized interest, plus distributions on preferred units.

As of March 31, 2010, $472.7 million in mortgage loans and $1,842.9 million in unsecured notes were outstanding with a weighted average interest rate of 6.47%. The interest rates on $2,152.5 million of mortgage loans and unsecured notes are fixed and range from 5.00% to 8.75%. For $163.1 million of mortgage loans, the interest rate floats at a spread to LIBOR. The interest rate on these loans at March 31, 2010 was 6.94%. The weighted average remaining term for the mortgage loans and unsecured notes is 4.4 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 March 31, 2010 are as follows (in thousands, except percentages):

General

The Company has continued to focus on the performance of the Same Store portfolio. In addition, the Company has continued to pursue development and acquisition opportunities and the strategic disposition of certain properties. The Company endeavors to maintain high occupancy levels while increasing rental rates and controlling costs, though the current economic environment and weak real estate fundamentals have pressured occupancy and created a declining rental rate environment.

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

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 REITs 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 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 (“FFO”) available to common shareholders also does not represent cash flows generated from operating, investing or financing activities as defined by GAAP. Funds from operations available to common shareholders for the three months ended March 31, 2010 and 2009 are as follows (in thousands, except per share amounts):

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.


Item 3.		Quantitative and Qualitative Disclosures about Market Risk

There have been no material changes to the Company’s exposure to market risk since its Annual Report on Form 10-K for the year ended December 31, 2009.


Item 4.		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 (i) recorded, processed, summarized and reported within the time periods specified in SEC’s rules and forms and (ii) accumulated and communicated to the Company’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Controls

There were no changes in the Company’s internal control over financial reporting during the quarter ended March 31, 2010 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II. OTHER INFORMATION


Item 1.		Legal Proceedings

The Company has been substituted for Republic Property Trust, a Maryland real estate investment trust, and Republic Property Limited Partnership, a Delaware limited partnership, (together, “Republic”) as a party to certain litigation as a result of the Company’s acquisition of Republic on October 4, 2007.

The litigation is described in the Company’s 2009 Annual Report on Form 10-K. There were no material developments in this litigation during the three months ended March 31, 2010.

While management currently believes that resolving these matters will not have a material adverse impact on our financial position, our results of operations or our cash flows, the litigation noted above is subject to inherent uncertainties and management’s view of these matters may change in the future. Were an unfavorable final outcome to occur, there exists the possibility of a material adverse impact on our financial position and the results of operations for the period in which the effect becomes capable of being reasonably estimated.


Item 1A.		Risk Factors

There have been no material changes to the risk factors disclosed in Item 1A of Part 1 “Risk Factors,” in our Form 10-K for the year ended December 31, 2009.
