Notes to Consolidated Financial Statements

March 31, 2012

(Unaudited)

NOTE 1—BUSINESS AND ORGANIZATION

Federal Realty Investment Trust (the “Trust”) is an equity real estate investment trust (“REIT”) specializing in the ownership, management, and redevelopment of retail and mixed-use properties. Our properties are located primarily in densely populated and affluent communities in strategically selected metropolitan markets in the Mid-Atlantic and Northeast regions of the United States, as well as in California. As of March 31, 2012, we owned or had a majority interest in community and neighborhood shopping centers and mixed-use properties which are operated as 87 predominantly retail real estate projects.

We operate in a manner intended to enable us to qualify as a REIT for federal income tax purposes. A REIT that distributes at least 90% of its taxable income to its shareholders each year and meets certain other conditions is not taxed on that portion of its taxable income which is distributed to its shareholders. Therefore, federal income taxes on our taxable income have been and are generally expected to be immaterial. We are obligated to pay state taxes, generally consisting of franchise or gross receipts taxes in certain states. Such state taxes also have not been material.

NOTE 2—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

Our consolidated financial statements include the accounts of the Trust, its corporate subsidiaries, and all entities in which the Trust has a controlling interest or has been determined to be the primary beneficiary of a variable interest entity (“VIE”). The equity interests of other investors are reflected as noncontrolling interests or redeemable noncontrolling interests. All significant intercompany transactions and balances are eliminated in consolidation. We account for our interests in joint ventures, which we do not control, using the equity method of accounting. Certain 2011 amounts have been reclassified to conform to current period presentation.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America, referred to as “GAAP,” requires management to make estimates and assumptions that in certain circumstances affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities, and revenues and expenses. These estimates are prepared using management’s best judgment, after considering past, current and expected events and economic conditions. Actual results could differ from these estimates.

Comprehensive Income

In June 2011, the FASB issued ASU 2011-05, “Comprehensive Income (Topic 220): Presentation of Comprehensive Income.” ASU 2011-05 eliminates the option to present components of other comprehensive income as part of the statement of shareholders’ equity and requires the presentation of components of net income and components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In December 2011, the FASB deferred the requirement to present reclassification adjustments for each component of accumulated other comprehensive income in both net income and other comprehensive income on the face of the financial statements. We adopted the standards effective January 1, 2012 and modified the presentation in our consolidated financial statements accordingly.

The components of comprehensive income are as follows:

	Three Months Ended March 31,
	2012			2011
	(In thousands)
Net income	$	44,122		$	32,384
Other comprehensive income	1,358			—
Comprehensive income	$	45,480		$	32,384
Net income attributable to noncontrolling interests	(1,136		)	(1,198		)
Comprehensive income attributable to the Trust	$	44,344		$	31,186

Other Recently Adopted Accounting Pronouncements

In May 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2011-04, “Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs.” The pronouncement was issued to provide a uniform framework for fair value measurements and related disclosures between U.S. GAAP and International Financial Reporting Standards (“IFRS”). ASU 2011-04 changes certain fair value measurement principles and enhances the disclosure requirements particularly for level 3 fair value measurements. We adopted the standard effective January 1, 2012 and it did not have a significant impact to our consolidated financial statements.

NOTE 3—REAL ESTATE

During 2012, we finalized the purchase price allocations for our December 2011 acquisitions of controlling interests in Montrose Crossing and Plaza El Segundo. The purchase price for Montrose Crossing was $141.5 million and our 89.9% ownership interest was $127.2 million which was funded with cash and our pro-rata share of $80.0 million of new mortgage debt.  Approximately $2.9 millionand $3.8 million of net assets acquired were allocated to other assets for "above market leases" and other liabilities for "below market leases", respectively. The purchase price for Plaza El Segundo was $192.7 million and our 48.2% ownership interest was funded with $8.5 million of cash and the assumption of our pro-rata share of the existing $175.0 million mortgage debt.  Approximately $7.5 million and $2.3 million of net assets acquired were allocated to other assets for "above market leases" and other liabilities for "below market leases", respectively. The balance sheet at December 31, 2011, has been adjusted to reflect the final purchase price allocation for both properties.

NOTE 4—REAL ESTATE PARTNERSHIPS

Federal/Lion Venture LP

We have a joint venture arrangement (the “Partnership”) with affiliates of a discretionary fund created and advised by ING Clarion Partners (“Clarion”). We own 30% of the equity in the Partnership and Clarion owns 70%. We hold a general partnership interest, however, Clarion also holds a general partnership interest and has substantive participating rights. We cannot make significant decisions without Clarion’s approval. Accordingly, we account for our interest in the Partnership using the equity method. As of March 31, 2012, the Partnership owned seven retail real estate properties. We are the manager of the Partnership and its properties, earning fees for acquisitions, dispositions, management, leasing, and financing. Intercompany profit generated from fees is eliminated in consolidation. We also have the opportunity to receive performance-based earnings through our Partnership interest. Accounting policies for the Partnership are similar to accounting policies followed by the Trust. The Partnership is subject to a buy-sell provision which is customary for real estate joint venture agreements and the industry. Either partner may initiate this provision at any time, which could result in either the sale of our interest or the use of available cash or borrowings to acquire Clarion’s interest.

Taurus Newbury Street JV II Limited Partnership

On October 31, 2011, our Newbury Street Partnership sold its entire portfolio of three buildings for $44.0 million.  As part of the sale, we received $34.6 million of the net proceeds which included the repayment of our $11.8 million loans. Due to the timing of receiving financial information from the general partner, our share of earnings was recorded one quarter in arrears. Therefore, we recognized the gain on sale of $11.9 million in the first quarter 2012. The deferred gain was included in "other liabilities and deferred credits" on the balance sheet at December 31, 2011.

NOTE 5—DEBT

During the three months ended March 31, 2012, our $400.0 million revolving credit facility had no amounts outstanding. Our revolving credit facility, term loan and certain notes require us to comply with various financial covenants, including the maintenance of minimum shareholders’ equity and debt coverage ratios and a maximum ratio of debt to net worth. As of March 31, 2012, we were in compliance with all loan covenants.

NOTE 6—FAIR VALUE OF FINANCIAL INSTRUMENTS

Except as disclosed below, the carrying amount of our financial instruments approximates their fair value. The fair value of our mortgages payable, notes payable and senior notes and debentures is sensitive to fluctuations in interest rates. Quoted market prices (Level 1) were used to estimate the fair value of our marketable senior notes and debentures and discounted cash flow analysis (Level 2) is generally used to estimate the fair value of our mortgages and notes payable. Considerable judgment is necessary to estimate the fair value of financial instruments. The estimates of fair value presented herein are not necessarily indicative of the amounts that could be realized upon disposition of the financial instruments. A summary of the carrying amount and fair value of our mortgages payable, notes payable and senior notes and debentures is as follows:

10

	March 31, 2012				December 31, 2011
	Carrying Value		Fair Value		Carrying Value		Fair Value
	(In thousands)
Mortgages and notes payable	$	1,038,982	$	1,091,798	$	1,042,682	$	1,099,273
Senior notes and debentures	$	1,004,584	$	1,094,273	$	1,004,635	$	1,085,309

As of March 31, 2012, we have two interest rate swap agreements with a notional amount of $275.0 million that are measured at fair value on a recurring basis. We assess effectiveness of our cash flow hedges both at inception and on an ongoing basis. The effective portion of changes in fair value of the interest rate swaps associated with our cash flow hedges is recorded in accumulated other comprehensive loss and is subsequently reclassified into interest expense as interest is incurred on the related variable rate debt. Within the next 12 months, we expect to reclassify an estimated $3.9 million as an increase to interest expense. Our cash flow hedges become ineffective if critical terms of the hedging instrument and the debt instrument do not perfectly match such as notional amounts, settlement dates, reset dates, calculation period and LIBOR rate. In addition, we evaluate the default risk of the counterparty by monitoring the credit-worthiness of the counterparty. When ineffectiveness exists, the ineffective portion of changes in fair value of the interest rate swaps associated with our cash flow hedges is recognized in earnings in the period affected. Hedge ineffectiveness did not impact earnings in 2012, and we do not anticipate it will have a significant effect in the future.

The fair values of the interest rate swap agreements are based on the estimated amounts we would receive or pay to terminate the contracts at the reporting date and are determined using interest rate pricing models and interest rate related observable inputs. The fair value of our swaps at March 31, 2012 was a liability of $2.6 million and is included in "accounts payable and accrued expenses" on our consolidated balance sheet. The change in valuation on our interest rate swaps was $1.4 million (including $1.0 million reclassified from other comprehensive income to earnings) for the three months ended March 31, 2012 and is included in "accumulated other comprehensive loss". A summary of our financial liabilities that are measured at fair value on a recurring basis, by level within the fair value hierarchy is as follows:

	March 31, 2012								December 31, 2011
	Level 1		Level 2		Level 3		Total		Level 1		Level 2		Level 3		Total

We are sometimes involved in lawsuits, warranty claims, and environmental matters arising in the ordinary course of business. Management makes assumptions and estimates concerning the likelihood and amount of any potential loss relating to these matters.

We are currently a party to various legal proceedings. We accrue a liability for litigation if an unfavorable outcome is probable and the amount of loss can be reasonably estimated. If an unfavorable outcome is probable and a reasonable estimate of the loss is a range, we accrue the best estimate within the range; however, if no amount within the range is a better estimate than any other amount, the minimum within the range is accrued. Legal fees related to litigation are expensed as incurred. We do not believe that the ultimate outcome of these matters, either individually or in the aggregate, could have a material adverse effect on our financial position or overall trends in results of operations; however, litigation is subject to inherent uncertainties. Also under our leases, tenants are typically obligated to indemnify us from and against all liabilities, costs and expenses imposed upon or asserted against us (1) as owner of the properties due to certain matters relating to the operation of the properties by the tenant, and (2) where appropriate, due to certain matters relating to the ownership of the properties prior to their acquisition by us.

Under the terms of certain partnership agreements, the partners have the right to exchange their operating partnership units for cash or the same number of our common shares, at our option. A total of 326,140 operating partnership units are outstanding which have a total fair value of $31.6 million, based on our closing stock price on March 31, 2012.

NOTE 12—EARNINGS PER SHARE

We have calculated earnings per share (“EPS”) under the two-class method. The two-class method is an earnings allocation methodology whereby EPS for each class of common stock and participating securities is calculated according to dividends declared and participation rights in undistributed earnings. For the three months ended March 31, 2012 and 2011, we had 0.3 million weighted average unvested shares outstanding, which are considered participating securities. Therefore, we have allocated our earnings for basic and diluted EPS between common shares and unvested shares; the portion of earnings allocated to the unvested shares is reflected as “earnings allocated to unvested shares” in the reconciliation below.

In the dilutive EPS calculation, dilutive stock options were calculated using the treasury stock method consistent with prior periods. There were no anti-dilutive stock options for the three months ended March 31, 2012. Approximately 0.1 million stock options have been excluded for the three months ended March 31, 2011 as they were anti-dilutive. The conversions of downREIT operating partnership units and 5.417% Series 1 Cumulative Convertible Preferred Shares are anti-dilutive for all periods presented and accordingly, have been excluded from the weighted average common shares used to compute diluted EPS.

ITEM 2.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Forward-Looking Statements

The following discussion should be read in conjunction with the consolidated interim financial statements and notes thereto appearing in Item 1 of this report and the more detailed information contained in our Annual Report on Form 10-K for the year ended December 31, 2011 filed with the Securities and Exchange Commission (the “SEC”) on February 16, 2012.

This Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, Section 21E of the Securities Exchange Act of 1934 and the Private Securities Litigation Reform Act of 1995. When we refer to forward-looking statements or information, sometimes we use words such as “may,” “will,” “could,” “should,” “plans,” “intends,” “expects,” “believes,” “estimates,” “anticipates” and “continues.” Forward-looking statements are not historical facts or guarantees of future performance and involve certain known and unknown risks, uncertainties, and other factors, many of which are outside our control, that could cause actual results to differ materially from those we describe.

Given these uncertainties, readers are cautioned not to place undue reliance on any forward-looking statements that we make, including those in this Quarterly Report on Form 10-Q. Except as may be required by law, we make no promise to update any of the forward-looking statements as a result of new information, future events or otherwise. You should carefully review the risks and the risk factors included in our Annual Report on Form 10-K for the year ended December 31, 2011 and under Part II, Item 1A in this Quarterly Report on Form 10-Q, before making any investments in us.

Overview

We are an equity real estate investment trust (“REIT”) specializing in the ownership, management, and redevelopment of high quality retail and mixed-use properties located primarily in densely populated and affluent communities in strategically selected metropolitan markets in the Northeast and Mid-Atlantic regions of the United States, as well as in California. As of March 31, 2012, we owned or had a majority interest in community and neighborhood shopping centers and mixed-use properties which are operated as 87 predominantly retail real estate projects comprising approximately 19.2 million square feet (excludes unconsolidated joint venture properties). In total, the real estate projects were 93.8% leased and 92.6% occupied at March 31, 2012. A joint venture in which we own a 30% interest owned seven retail real estate projects totaling approximately 1.0 million square feet as of March 31, 2012. In total, the joint venture properties in which we own a 30% interest were 87.8% leased and occupied at March 31, 2012.

2012 Significant Equity Transactions

On February 24, 2011, we entered into an at the market (“ATM”) equity program in which we may from time to time offer and sell common shares having an aggregate offering price of up to $300.0 million. We intend to use the net proceeds to fund potential acquisition opportunities, fund our development and redevelopment pipeline, repay amounts outstanding under our revolving credit facility and/or for general corporate purposes. For the three months ended March 31, 2012, we issued 220,792 common shares at a weighted average price per share of $96.58 for net cash proceeds of $21.0 million and paid $0.3 million in commissions related to the sales of these common shares. As of March 31, 2012, we had the capacity to issue up to $137.0 million in common shares under our ATM equity program.

Final Purchase Price Allocation of 2011 Property Acquisitions

During 2012, we finalized the purchase price allocations for our December 2011 acquisitions of controlling interests in Montrose Crossing and Plaza El Segundo. The purchase price for Montrose Crossing was $141.5 million and our 89.9% ownership interest was $127.2 million which was funded with cash and our pro-rata share of $80.0 million of new mortgage debt.  Approximately $2.9 million and $3.8 million of net assets acquired were allocated to other assets for "above market leases" and other liabilities for "below market leases", respectively. The purchase price for Plaza El Segundo was $192.7 million and our 48.2% ownership interest was funded with $8.5 million of cash and the assumption of our pro-rata share of the existing $175.0 million mortgage debt.  Approximately $7.5 million and $2.3 million of net assets acquired were allocated to other assets for "above market leases" and other liabilities for "below market leases", respectively. The balance sheet at December 31, 2011, has been adjusted to reflect the final purchase price allocation for both properties.

Capitalized Costs

Certain external and internal costs directly related to the development, redevelopment and leasing of real estate, including pre-

15

construction costs, real estate taxes, insurance, construction costs and salaries and related costs of personnel directly involved, are capitalized. We capitalized external and internal costs related to both development and redevelopment activities of $16 million and $2 million, respectively, for the three months ended March 31, 2012 and $17 million and $1 million, respectively, for the three months ended March 31, 2011. We capitalized external and internal costs related to other property improvements of $10 million and less than $1 million, respectively, for the three months ended March 31, 2012 and $8 million and less than $1 million, respectively, for the three months ended March 31, 2011. We capitalized external and internal costs related to leasing activities of $1 million and $1 million, respectively, for the three months ended March 31, 2012 and $3 million and $1 million, respectively, for the three months ended March 31, 2011. The amount of capitalized internal costs for salaries and related benefits for development and redevelopment activities, other property improvements, and leasing activities were $1 million, less than $1 million, and $1 million, respectively, for both the three months ended March 31, 2012 and 2011.

Outlook

We seek growth in earnings, funds from operations, and cash flows primarily through a combination of the following:

• growth in our portfolio from property development and redevelopments,

• growth in our same-center portfolio, and

• expansion of our portfolio through property acquisitions.

Our properties are predominately located in densely populated, affluent areas with high barriers to entry which allow us to take advantage of redevelopment opportunities that enhance our operating performance through renovation, expansion, reconfiguration, and/or retenanting. We evaluate our properties on an ongoing basis to identify these types of opportunities. In 2012, we expect to have redevelopment projects stabilizing with projected costs of approximately $57 million.

Additionally, we continue to invest in the development at Assembly Row which is a long-term development project we expect to be involved in over the coming years. The carrying value of the development portion of this project at March 31, 2012 is approximately $155 million. The project currently has zoning entitlements to build 2.3 million square feet of commercial-use buildings, 2,100 residential units, and a 200 room hotel. In December 2011, we entered into agreements with AvalonBay Communities ("AvalonBay") for a portion of the first phase of residential and retail development at Assembly Row which will include 575 residential units (by AvalonBay) and approximately 323,000 square feet of retail space.  The Massachusetts Bay Transit Authority (MBTA) will also construct the new orange line T-Stop at the property.   Construction commenced during first quarter 2012 and we expect the first phase to be stabilized in 2015. We will also continue our infrastructure work during 2012. We expect to invest between $20 million and $40 million in 2012, net of expected public funding.

We continue our predevelopment work related to the long-term redevelopment of Mid-Pike Plaza in Rockville, Maryland, which will be renamed Pike & Rose, a long-term, multi-phased, mixed-use project.  The property currently has zoning entitlements to build 1.7 million square feet of commercial-use buildings and 1,583 residential units. Phase I of Pike & Rose involves demolition of roughly 25% of the existing GLA at Mid-Pike Plaza and construction of 493 residential units, 151,000 square feet of retail space and 79,000 square of office space. We expect construction of Phase I to commence in mid-2012 with stabilization in 2015/2016.  We expect to invest between $40 million and $60 million in 2012.

The development of future phases of Assembly Row, Pike & Rose and Santana Row will be pursued opportunistically based on, among other things, market conditions, our evaluation of whether those phases will generate an appropriate financial return and our ability to structure the development of those future phases, through entitlement sales, third party capital investment or otherwise, in a way that should mitigate our risk of those future phases.

Our same-center growth is primarily driven by increases in rental rates on new leases and lease renewals and changes in portfolio occupancy. Over the long-term, the infill nature and strong demographics of our properties provide a strategic advantage allowing us to maintain relatively high occupancy and increase rental rates. We have continued to see signs of improvement for many of our tenants as well as increased interest from prospective tenants for our retail spaces. While there can be no assurance that these positive signs will continue, we remain cautiously optimistic regarding the improved trends we have seen over the past two years.  While we have seen improvements over much of our portfolio, we continue to see some tenants being negatively impacted by the economic environment and some filing for bankruptcy, though at a lower rate than in previous years.  We believe the locations of our centers and diverse tenant base mitigates the negative impact of the economic environment, however, any reduction in our tenants' abilities to pay base rent, percentage rent or other charges, will adversely affect our financial condition and results of operations.  We expect to continue to see small changes in occupancy over the short term and expect increases in occupancy and rental rates to be a driver of our same-center growth over the long term as we are able to re-lease vacant spaces. We seek to maintain a mix of strong national, regional, and local retailers. At March 31, 2012, no single tenant accounted for more than 2.5% of annualized base rent.

We continue to review acquisition opportunities in our primary markets that complement our portfolio and provide long-term

16

growth opportunities. Generally, our acquisitions do not initially contribute significantly to earnings growth; however, they provide long-term re-leasing growth, redevelopment opportunities, and other strategic opportunities. Any growth from acquisitions is contingent on our ability to find properties that meet our qualitative standards at prices that meet our financial hurdles. Changes in interest rates may affect our success in achieving earnings growth through acquisitions by affecting both the price that must be paid to acquire a property, as well as our ability to economically finance the property acquisition. Generally, our acquisitions are initially financed by available cash and/or borrowings under our revolving credit facility which may be repaid later with funds raised through the issuance of new equity or new long-term debt. On occasion we also finance our acquisitions through the issuance of common shares, preferred shares, or downREIT units as well as through new or assumed mortgages.

At March 31, 2012, the leasable square feet in our properties was 92.6% occupied and 93.8% leased. The leased rate is higher than the occupied rate due to leased spaces that are being redeveloped or improved or that are awaiting permits and, therefore, are not yet ready to be occupied. Our occupancy and leased rates are subject to variability over time due to factors including acquisitions, the timing of the start and stabilization of our redevelopment projects, lease expirations and tenant bankruptcies.

Lease Rollovers

For the first quarter 2012, we signed leases for a total of 473,000 square feet of retail space including 461,000 square feet of comparable space leases (leases for which there was a prior tenant) at an average rental increase of 17% on a cash basis and 24% on a straight-line basis. New leases for comparable spaces were signed for 224,000 square feet at an average rental increase of 31% on a cash basis and 40% on a straight-line basis. Renewals for comparable spaces were signed for 237,000 square feet at an average rental increase of 4% on a cash basis and 10% on a straight-line basis.

The rental increases associated with comparable spaces generally include all leases signed in arms-length transactions reflecting market leverage between landlords and tenants during the period. The comparison between average rent for expiring leases and new leases is determined by including minimum rent and percentage rent paid on the expiring lease and minimum rent and in some instances, projections of first lease year percentage rent, to be paid on the new lease. In some instances, management exercises judgment as to how to most effectively reflect the comparability of spaces reported in this calculation. The change in rental income on comparable space leases is impacted by numerous factors including current market rates, location, individual tenant creditworthiness, use of space, market conditions when the expiring lease was signed, capital investment made in the space and the specific lease structure.

The leases signed in 2012 generally become effective over the following two years though some may not become effective until 2014 and beyond. Further, there is risk that some new tenants will not ultimately take possession of their space and that tenants for both new and renewal leases may not pay all of their contractual rent due to operating, financing or other matters. However, these increases do provide information about the tenant/landlord relationship and the potential increase we may achieve in rental income over time.

In 2012, we expect a similar level of leasing activity compared to prior years with overall positive increases in rental income. However, changes in rental income associated with individual signed leases on comparable spaces may be positive or negative, and we can provide no assurance that the rents on new leases will continue to increase at the above disclosed levels, if at all.

Same-Center

Throughout this section, we have provided certain information on a “same-center” basis. Information provided on a same-center basis includes the results of properties that we owned and operated for the entirety of both periods being compared except for properties for which significant redevelopment or expansion occurred during either of the periods being compared and properties classified as discontinued operations. As of March 31, 2012, all or a portion of 78 properties were considered same-center and seven were considered redevelopment or expansion.   Three properties were removed from same-center and one property was added to same-center compared to the designations as of December 31, 2011.  While there is judgment surrounding changes in designations, we typically move redevelopment properties to same-center once they have stabilized, which is typically considered 95% occupancy or when the growth expected from the redevelopment has been included in the comparable periods.  We typically remove properties from same center when the redevelopment has or is expected to have a significant impact to property operating income within the calendar year.  Acquisitions are moved to same-center once we have owned the property for comparable periods and the property is not under significant development or expansion.

Property Revenues

Total property revenue increased $8.6 million, or 6.3%, to $146.3 million in the three months ended March 31, 2012 compared to $137.6 million in the three months ended March 31, 2011. The percentage occupied at our shopping centers decreased to 92.6% at March 31, 2012 compared to 93.5% at March 31, 2011. Changes in the components of property revenue are discussed below.

Rental Income

Rental income consists primarily of minimum rent, cost reimbursements from tenants and percentage rent. Rental income increased $6.2 million, or 4.6%, to $140.7 million in the three months ended March 31, 2012 compared to $134.4 million in the three months ended March 31, 2011 due primarily to the following:

• an increase of $6.9 million attributable to properties acquired in 2011, and

• an increase of $0.8 million at redevelopment properties due primarily to increased occupancy at certain properties and higher rental rates on new and renewal leases,

partially offset by

• a decrease of $1.8 million at same-center properties due primarily to lower recovery income as a result of lower recoverable expenses (primarily snow removal costs).

Other Property Income

Other property income increased $2.3 million, or 108.7%, to $4.4 million in the three months ended March 31, 2012 compared to $2.1 million in the three months ended March 31, 2011. Included in other property income are items which, although recurring, tend to fluctuate more than rental income from period to period, such as lease termination fees. This increase is

18

primarily due to an increase in lease termination fees at same-center properties.

Property Expenses

Total property expenses decreased $2.6 million, or 5.9%, to $42.2 million in the three months ended March 31, 2012 compared to $44.8 million in the three months ended March 31, 2011. Changes in the components of property expenses are discussed below.

Rental Expenses

Rental expenses decreased $3.3 million, or 11.2%, to $26.1 million in the three months ended March 31, 2012 compared to $29.4 million in the three months ended March 31, 2011. This decrease is primarily due to the following:

• a decrease of $4.1 million in repairs and maintenance at same-center properties primarily due to lower snow removal costs, and

• a decrease of $0.3 million in bad debt expense at same-center properties,

partially offset by

• an increase of $0.6 million related to properties acquired in 2011, and

• an increase of $0.6 million in other operating costs.

As a result of the changes in rental income, other property income and rental expenses as discussed above, rental expenses as a percentage of rental income plus other property income decreased to 18.0% in the three months ended March 31, 2012 from 21.5% in the three months ended March 31, 2011.

Real Estate Taxes

Real estate tax expense increased $0.7 million, or 4.2% to $16.1 million in the three months ended March 31, 2012 compared to $15.4 million in the three months ended March 31, 2011 due primarily to $0.9 million from properties acquired in 2011 partially offset by tax refunds at certain same-center properties.

Property Operating Income

Property operating income increased $11.3 million, or 12.2%, to $104.1 million in the three months ended March 31, 2012 compared to $92.8 million in the three months ended March 31, 2011. This increase is primarily due to properties acquired in 2011 and growth in earnings at same-center and redevelopment properties.

Other

Interest Expense

Interest expense increased $3.7 million, or 15.0%, to $28.8 million in the three months ended March 31, 2012 compared to $25.0 million in the three months ended March 31, 2011. This increase is due primarily to the following:

• an increase of $3.2 million due to mortgage loans secured by Plaza El Segundo and Montrose Crossing both of which were acquired in 2011,

• an increase of $0.9 million due to a higher overall weighted average borrowing rate, and

• an increase of $0.3 million due to higher borrowings

partially offset by

• an increase of $0.7 million in capitalized interest.

Gross interest costs were $31.3 million and $26.8 million in the three months ended March 31, 2012 and 2011, respectively. Capitalized interest was $2.5 million and $1.8 million in the three months ended March 31, 2012 and 2011, respectively.

Early Extinguishment of Debt

The $0.3 million of income from early extinguishment of debt in the three months ended March 31, 2011 is due to the write-off of unamortized debt premium net of a 3.0% prepayment premium and unamortized debt fees related to the payoff of our mortgage loan on Tower Shops prior to its contractual prepayment date.

19

General and Administrative Expense

General and administrative expense increased $1.0 million, or 15.7%, to $7.0 million in in the three months ended March 31, 2012 from $6.1 million in the three months ended March 31, 2011. This increase is due primarily to higher personnel related costs partially offset by lower acquisition costs resulting from a lower volume of potential acquisitions.

Depreciation and Amortization

Depreciation and amortization expense increased $6.2 million, or 20.2%, to $36.6 million in the three months ended March 31, 2012 from $30.4 million in the three months ended March 31, 2011. This increase is due primarily to 2011 acquisitions, accelerated depreciation due to the change in use of certain redevelopment buildings and capital improvements at same-center properties.

Discontinued Operations— Income

Income from discontinued operations represents the operating income of properties that have been disposed or will be disposed, which is required to be reported separately from results of ongoing operations. The reported operating income of $0.4 million for the three months ended March 31, 2011 primarily represents the operating income for the period during which we owned properties sold/disposed of in 2011.

Gain on Sale of Real Estate in Real Estate Partnership

The $11.9 million gain on sale of real estate in real estate partnership in the three months ended March 31, 2012 is due to the sale of our Newbury Street Partnership's entire portfolio of three buildings on October 31, 2011. Due to the timing of receiving financial information from the general partner, our share of earnings was recorded one quarter in arrears. Therefore, we recognized the gain on sale of $11.9 million in the three months ended March 31, 2012.

Recently Adopted Accounting Pronouncements

In May 2011, the FASB issued Accounting Standards Update (“ASU”) 2011-04, “Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs.” The pronouncement was issued to provide a uniform framework for fair value measurements and related disclosures between U.S. GAAP and International Financial Reporting Standards (“IFRS”). ASU 2011-04 changes certain fair value measurement principles and enhances the disclosure requirements particularly for level 3 fair value measurements. We adopted the standard effective January 1, 2012 and it did not have a significant impact to our consolidated financial statements.

In June 2011, the FASB issued ASU 2011-05, “Comprehensive Income (Topic 220): Presentation of Comprehensive Income.” ASU 2011-05 eliminates the option to present components of other comprehensive income as part of the statement of shareholders’ equity and requires the presentation of components of net income and components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In December 2011, the FASB deferred the requirement to present reclassification adjustments for each component of accumulated other comprehensive income in both net income and other comprehensive income on the face of the financial statements. We adopted the standards effective January 1, 2012 and modified the presentation in our consolidated financial statements accordingly.

Liquidity and Capital Resources

Due to the nature of our business and strategy, we typically generate significant amounts of cash from operations. The cash generated from operations is primarily paid to our common and preferred shareholders in the form of dividends. As a REIT, we must generally make annual distributions to shareholders of at least 90% of our taxable income.

Our short-term liquidity requirements consist primarily of normal recurring operating expenses, obligations under our capital and operating leases, regular debt service requirements (including debt service relating to additional or replacement debt, as well as scheduled debt maturities), recurring expenditures, non-recurring expenditures (such as tenant improvements and redevelopments) and dividends to common and preferred shareholders. Our long-term capital requirements consist primarily of maturities under our long-term debt agreements, development and redevelopment costs and potential acquisitions.

We intend to operate with and maintain a conservative capital structure that will allow us to maintain strong debt service coverage and fixed-charge coverage ratios as part of our commitment to investment-grade debt ratings. In the short and long term, we may seek to obtain funds through the issuance of additional equity, unsecured and/or secured debt financings, joint venture relationships relating to existing properties or new acquisitions, and property dispositions that are consistent with this conservative structure.

Cash and cash equivalents increased $1.4 million to $69.2 million at March 31, 2012; however, cash and cash equivalents are not the only indicator of our liquidity. We have a $400.0 million unsecured revolving credit facility which matures on July 6, 2015 and had no borrowings during the three months ended March 31, 2012. In addition, we have an option (subject to bank approval) to increase the credit facility through an accordion feature to $800.0 million. Our $275.0 million unsecured term loan which matures on November 21, 2018 also has an option (subject to bank approval) to increase the term loan through an accordion feature to $350.0 million. As of March 31, 2012, we had the capacity to issue up to $137.0 million in common shares under our ATM equity program.

We have approximately $192 million of debt maturing in 2012, of which $175.0 million relates to our 6.00% senior notes that mature in July 2012. We currently believe that cash flows from operations, cash on hand, our ATM equity program, our revolving credit facility and our general ability to access the capital markets will be sufficient to finance our operations and fund our debt service requirements (including maturities) and capital expenditures.

Our overall capital requirements during 2012 will depend upon acquisition opportunities, the level of improvements and redevelopments on existing properties and the timing and cost of development of Assembly Row, Pike & Rose and future phases of Santana Row. While the amount of future expenditures will depend on numerous factors, we expect to incur higher amounts in 2012 compared to those incurred in 2011 related to capital investments for development, redevelopment and existing properties as we progress with our active development pipeline. These amounts will be funded on a short-term basis with cash flow from operations, cash on hand, our revolving credit facility and/or proceeds from shares issued under our ATM equity program, and on a long-term basis, with long-term debt or equity. If necessary, we may access the debt or equity capital markets to finance significant acquisitions. Given our past ability to access the capital markets, we expect debt or equity to be available to us. Although there is no intent at this time, if market conditions deteriorate, we may also delay the timing of certain development and redevelopment projects as well as limit future acquisitions, reduce our operating expenditures, or re-evaluate our dividend policy.

In addition to conditions in the capital markets which could affect our ability to access those markets, the following factors could affect our ability to meet our liquidity requirements:

• restrictions in our debt instruments or preferred shares may limit us from incurring debt or issuing equity at all, or on acceptable terms under then-prevailing market conditions; and

• we may be unable to service additional or replacement debt due to increases in interest rates or a decline in our operating performance.

Summary of Cash Flows

	Three Months Ended March 31,
	2012			2011
	(In thousands)
Cash provided by operating activities	$	69,457		$	45,999
Cash used in investing activities	(39,282		)	(52,908		)
Cash (used in) provided by financing activities	(28,799		)	1,113
Increase (decrease) in cash and cash equivalents	1,376			(5,796		)
Cash and cash equivalents, beginning of year	67,806			15,797
Cash and cash equivalents, end of period	$	69,182		$	10,001

Net cash provided by operating activities increased $23.5 million to $69.5 million during the three months ended March 31, 2012 from $46.0 million during the three months ended March 31, 2011. The increase was primarily attributable to the payment in 2011 of the $16.2 million final judgment related to a previously disclosed lawsuit offset by higher net income before certain non-cash items.

Net cash used in investing activities decreased $13.6 million to $39.3 million during the three months ended March 31, 2012 from $52.9 million during the three months ended March 31, 2011. The decrease was primarily attributable to:

• $19.2 million decrease in acquisitions of real estate due to the January 2011 Tower Shops acquisition and no acquisitions in 2012,

partially offset by

• $6.9 million increase in capital investments.

Net cash used in financing activities increased $29.9 million to $28.8 million during the three months ended March 31, 2012

21

compared to $1.1 million of cash provided during the three months ended March 31, 2011. The increase was primarily attributable to:

• $115.0 million decrease in net borrowings on our revolving credit facility, and

• $26.1 million decrease in net proceeds from the issuance of common shares due primarily to the sale of 0.6 million shares under our ATM equity program in the three months ended March 31, 2011 compared to 0.2 million in the three months ended March 31, 2012,

partially offset by

• $75.0 million repayment of 4.50% senior notes in February 2011, and

• $42.0 million decrease in repayment of mortgages, capital leases and notes payable due to the $41.0 million payoff of the Tower Shops mortgage assumed with the acquisition in January 2011.

Off-Balance Sheet Arrangements

We have a joint venture arrangement (the “Partnership”) with affiliates of a discretionary fund created and advised by ING Clarion Partners (“Clarion”). We own 30% of the equity in the Partnership and Clarion owns 70%. We hold a general partnership interest, however, Clarion also holds a general partnership interest and has substantive participating rights. We cannot make significant decisions without Clarion’s approval. Accordingly, we account for our interest in the Partnership using the equity method. As of March 31, 2012, the Partnership owned seven retail real estate properties. We are the manager of the Partnership and its properties, earning fees for acquisitions, management, leasing and financing. We also have the opportunity to receive performance-based earnings through our Partnership interest. The Partnership is subject to a buy-sell provision which is customary in real estate joint venture agreements and the industry. Either partner may initiate this provision at any time, which could result in either the sale of our interest or the use of available cash or borrowings to acquire Clarion’s interest. Accounting policies for the Partnership are similar to accounting policies followed by the Trust. At March 31, 2012, our investment in the Partnership was $34.2 million and the Partnership had approximately $57.3 million of mortgages payable outstanding.

On October 31, 2011, our Newbury Street Partnership sold its entire portfolio of three buildings for $44.0 million.  As part of the sale, we received $34.6 million of the net proceeds which included the repayment of our $11.8 million loans. Due to the timing of receiving financial information from the general partner, our share of earnings was recorded one quarter in arrears. Therefore, we recognized the gain on sale of $11.9 million in the first quarter 2012.

_____________________

1) Mortgages payable do not include our 30% share ($17.2 million) of the $57.3 million debt of the partnership with a discretionary fund created and advised by ING Clarion Partners.

2) The interest rate of 6.04% represents the weighted average interest rate for two mortgage loans secured by this property. The loan balance represents an interest only loan of $4.4 million at a stated rate of 6.18% and the remaining balance at a stated rate of 5.96%.

3) We acquired control of Melville Mall through a 20-year master lease and secondary financing. Because we control the activities that most significantly impact this property and retain substantially all of the economic benefit and risk associated with it, this property is consolidated and the mortgage loan is reflected on the balance sheet, though it is not our legal obligation.

4) The interest rate is fixed at 5.66% for the first ten years and then will be reset to a market rate in 2013. The lender has the option to call the loan on April 15, 2013 or any time thereafter.

5) The interest rate of 3.10% represents the weighted average interest rate for two unsecured fixed rate notes payable. These notes mature on May 1, 2012 and January 31, 2013.

6) We entered into two interest rate swap agreements that effectively fix the rate on the term loan at 3.17%.

7) No amount was drawn under our revolving credit facility during the three months ended March 31, 2012.

8) The bonds require monthly interest only payments through maturity. The bonds bear interest at a variable rate determined weekly, which would enable the bonds to be remarketed at 100% of their principal amount. The Escondido Promenade property is not encumbered by a lien.

Our revolving credit facility, term loan and other debt agreements include financial and other covenants that may limit our operating activities in the future. As of March 31, 2012, we were in compliance with all of the financial and other covenants. If we were to breach any of our debt covenants and did not cure the breach within an applicable cure period, our lenders could require us to repay the debt immediately and, if the debt is secured, could immediately begin proceedings to take possession of the property securing the loan. Many of our debt arrangements, including our public notes, term loan and our revolving credit facility, are cross-defaulted, which means that the lenders under those debt arrangements can put us in default and require immediate repayment of their debt if we breach and fail to cure a default under certain of our other debt obligations. As a result, any default under our debt covenants could have an adverse effect on our financial condition, our results of operations, our ability to meet our obligations and the market value of our shares. Our organizational documents do not limit the level or amount of debt that we may incur.

The following is a summary of our scheduled principal repayments as of March 31, 2012:

	Unsecured			Secured			Capital Lease		Total
	(In thousands)
2012	$	185,255		$	15,634		$	18	$	200,907
2013	135,030			73,521		(1)	22		208,573
2014	150,000			157,838			25		307,863
2015	—		(2)	204,936			27		204,963
2016	134,400			2,521			30		136,951
Thereafter	694,200			280,163			71,586		1,045,949
	$	1,298,885		$	734,613		$	71,708	$	2,105,206	(3)

_____________________

1) Includes the repayment of the outstanding mortgage payable balance on Mount Vernon. The lender has the option to call the loan on April 15, 2013 or any time thereafter.

2) Our $400.0 million revolving credit facility matures on July 6, 2015, subject to a one-year extension at our option. As of March 31, 2012, there was $0 drawn under this credit facility.

3) The total debt maturities differs from the total reported on the consolidated balance sheet due to the unamortized net premium or discount on certain mortgage loans, senior notes and debentures as of March 31, 2012.

Interest Rate Hedging

We may use derivative instruments to manage exposure to variable interest rate risk. We generally enter into interest rate swaps to manage our exposure to variable interest rate risk and treasury locks to manage the risk of interest rates rising prior to the issuance of debt. We enter into derivative instruments that qualify as cash flow hedges and do not enter into derivative instruments for speculative purposes.

The interest rate swaps associated with our cash flow hedges are recorded at fair value on a recurring basis. We assess effectiveness of our cash flow hedges both at inception and on an ongoing basis. The effective portion of changes in fair value of the interest rate swaps associated with our cash flow hedges is recorded in other comprehensive income which is included in accumulated other comprehensive loss on our consolidated balance sheet and our consolidated statement of of shareholders' equity. Our cash flow hedges become ineffective if critical terms of the hedging instrument and the debt instrument do not perfectly match such as notional amounts, settlement dates, reset dates, calculation period and LIBOR rate. In addition, we evaluate the default risk of the counterparty by monitoring the credit-worthiness of the counterparty which includes reviewing debt ratings and financial performance. However, management does not anticipate non-performance by the counterparty. If a cash flow hedge is deemed ineffective, the ineffective portion of changes in fair value of the interest rate swaps associated with our cash flow hedges is recognized in earnings in the period affected.

In November 2011, we entered into two interest rate swap agreements that effectively fixed the rate on the term loan at 3.17%. Both swaps were designated and qualified as cash flow hedges and were recorded at fair value. Hedge ineffectiveness did not impact earnings in 2012, and we do not anticipate it will have a significant effect in the future.

REIT Qualification

We intend to maintain our qualification as a REIT under Section 856(c) of the Code. As a REIT, we generally will not be subject to corporate federal income taxes on income we distribute to our shareholders as long as we satisfy certain technical requirements of the Code, including the requirement to distribute at least 90% of our taxable income to our shareholders.

Funds From Operations

Funds from operations (“FFO”) is a supplemental non-GAAP financial measure of real estate companies’ operating performance. The National Association of Real Estate Investment Trusts (“NAREIT”) defines FFO as follows: net income, computed in accordance with the U.S. GAAP, plus real estate related depreciation and amortization and excluding extraordinary items, gains and losses on the sale of real estate, and impairment write-downs of depreciable real estate. We compute FFO in accordance with the NAREIT definition, and we have historically reported our FFO available for common shareholders in addition to our net income and net cash provided by operating activities. It should be noted that FFO:

• does not represent cash flows from operating activities in accordance with GAAP (which, unlike FFO, generally reflects all cash effects of transactions and other events in the determination of net income);

• should not be considered an alternative to net income as an indication of our performance; and

• is not necessarily indicative of cash flow as a measure of liquidity or ability to fund cash needs, including the payment of dividends.

We consider FFO available for common shareholders a meaningful, additional measure of operating performance primarily because it excludes the assumption that the value of the real estate assets diminishes predictably over time, as implied by the historical cost convention of GAAP and the recording of depreciation. We use FFO primarily as one of several means of assessing our operating performance in comparison with other REITs. Comparison of our presentation of FFO to similarly titled measures for other REITs may not necessarily be meaningful due to possible differences in the application of the NAREIT definition used by such REITs.

An increase or decrease in FFO available for common shareholders does not necessarily result in an increase or decrease in aggregate distributions because our Board of Trustees is not required to increase distributions on a quarterly basis unless necessary for us to maintain REIT status. However, we must distribute at least 90% of our taxable income to remain qualified as a REIT. Therefore, a significant increase in FFO will generally require an increase in distributions to shareholders although not necessarily on a proportionate basis.

25

The reconciliation of net income to FFO available for common shareholders is as follows:

	Three Months Ended March 31,
	2012			2011
	(In thousands)
Net income	$	44,122		$	32,384

Depreciation and amortization of real estate assets	32,415			27,589
Amortization of initial direct costs of leases	2,936			2,240
Depreciation of joint venture real estate assets	381			427

Weighted average number of common shares, diluted (1)	63,943			61,991
Funds from operations available for common shareholders, per diluted share	$	1.04		$	0.99

_____________________

(1) The weighted average common shares used to compute FFO per diluted common share includes operating partnership units that were excluded from the computation of diluted EPS. Conversion of these operating partnership units is dilutive in the computation of FFO per diluted common share but is anti-dilutive for the computation of diluted EPS for the periods presented.

ITEM 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our use of financial instruments, such as debt instruments, subjects us to market risk which may affect our future earnings and cash flows, as well as the fair value of our assets. Market risk generally refers to the risk of loss from changes in interest rates and market prices. We manage our market risk by attempting to match anticipated inflow of cash from our operating, investing and financing activities with anticipated outflow of cash to fund debt payments, dividends to common and preferred shareholders, investments, capital expenditures and other cash requirements.

We may enter into certain types of derivative financial instruments to further reduce interest rate risk. We use interest rate protection and swap agreements, for example, to convert some of our variable rate debt to a fixed-rate basis or to hedge anticipated financing transactions. We use derivatives for hedging purposes rather than speculation and do not enter into financial instruments for trading purposes. As of March 31, 2012, we were party to two interest rate swap agreements that effectively fixed the rate on the term loan at 3.17%.

Interest Rate Risk

The following discusses the effect of hypothetical changes in market rates of interest on interest expense for our variable rate debt and on the fair value of our total outstanding debt, including our fixed-rate debt. Interest rate risk amounts were determined by considering the impact of hypothetical interest rates on our debt. Quoted market prices were used to estimate the fair value of our marketable senior notes and debentures and discounted cash flow analysis is generally used to estimate the fair value of our mortgages and notes payable. Considerable judgment is necessary to estimate the fair value of financial instruments. This analysis does not purport to take into account all of the factors that may affect our debt, such as the effect that a changing interest rate environment could have on the overall level of economic activity or the action that our management might take to reduce our exposure to the change. This analysis assumes no change in our financial structure.

Fixed Interest Rate Debt

The majority of our outstanding debt obligations (maturing at various times through 2031 or, with respect to capital lease obligations through 2106) have fixed interest rates which limit the risk of fluctuating interest rates. However, interest rate fluctuations may affect the fair value of our fixed rate debt instruments. At March 31, 2012, we had $2.1 billion of fixed-rate debt outstanding, including our $275.0 million term loan as the rate is effectively fixed by two interest rate swap agreements,

26

and $71.7 million of capital lease obligations. If market interest rates used to calculate the fair value on our fixed-rate debt instruments at March 31, 2012 had been 1.0% higher, the fair value of those debt instruments on that date would have decreased by approximately $66.1 million. If market interest rates used to calculate the fair value on our fixed-rate debt instruments at March 31, 2012 had been 1.0% lower, the fair value of those debt instruments on that date would have increased by approximately $70.1 million.

Variable Interest Rate Debt

Generally, we believe that our primary interest rate risk is due to fluctuations in interest rates on our variable rate debt. At March 31, 2012, we had $9.4 million of variable rate debt outstanding which consisted of municipal bonds. Our revolving credit facility had no outstanding balance as of March 31, 2012. Based upon this amount of variable rate debt and the specific terms, if market interest rates increased 1.0%, our annual interest expense would increase by approximately $0.1 million, and our net income and cash flows for the year would decrease by approximately $0.1 million. Conversely, if market interest rates decreased 1.0%, our annual interest expense would decrease by less than $0.1 million with a corresponding increase in our net income and cash flows for the year.

ITEM 4.    CONTROLS AND PROCEDURES

Periodic Evaluation and Conclusion of Disclosure Controls and Procedures

An evaluation has been performed, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of March 31, 2012. Based on this evaluation, our management, including our Chief Executive Officer and Chief Financial Officer, concluded that our disclosure controls and procedures were effective as of March 31, 2012 to provide reasonable assurance that information required to be disclosed in our reports filed or submitted under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC.

Changes in Internal Control Over Financial Reporting

There has been no change in our internal control over financial reporting during quarterly period covered by this reports that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION

ITEM 1.    LEGAL PROCEEDINGS

None.

ITEM 1A.    RISK FACTORS

There have been no material changes to the risk factors previously disclosed in our Annual Report for the year ended December 31, 2011 filed with the SEC on February 16, 2012. These factors include, but are not limited to, the following:

• risks that our tenants will not pay rent, may vacate early or may file for bankruptcy or that we may be unable to renew leases or re-let space at favorable rents as leases expire;

• risks that we may not be able to proceed with or obtain necessary approvals for any redevelopment or renovation project, and that completion of anticipated or ongoing property redevelopment or renovation projects that we do pursue may cost more, take more time to complete or fail to perform as expected;

• risk that we are investing a significant amount in ground-up development projects that may be dependent on third parties to deliver critical aspects of certain projects, requires spending a substantial amount upfront in infrastructure, and assumes receipt of public funding which has been committed but not entirely funded;

• risks normally associated with the real estate industry, including risks that:

• occupancy levels at our properties and the amount of rent that we receive from our properties may be lower than expected,

• new acquisitions may fail to perform as expected,

27

• competition for acquisitions could result in increased prices for acquisitions,

• environmental issues may develop at our properties and result in unanticipated costs, and

• because real estate is illiquid, we may not be able to sell properties when appropriate;

• risks that our growth will be limited if we cannot obtain additional capital;

• risks associated with general economic conditions, including local economic conditions in our geographic markets;

• risks of financing, such as our ability to consummate additional financings or obtain replacement financing on terms which are acceptable to us, our ability to meet existing financial covenants and the limitations imposed on our operations by those covenants, and the possibility of increases in interest rates that would result in increased interest expense; and

• risks related to our status as a real estate investment trust, commonly referred to as a REIT, for federal income tax purposes, such as the existence of complex tax regulations relating to our status as a REIT, the effect of future changes in REIT requirements as a result of new legislation, and the adverse consequences of the failure to qualify as a REIT.

Real Estate Acquisitions Dispositions Discontinued Operations Text Block

During 2012, we finalized the purchase price allocations for our December 2011 acquisitions of controlling interests in Montrose Crossing and Plaza El Segundo. The purchase price for Montrose Crossing was $141.5 million and our 89.9% ownership interest was $127.2 million which was funded with cash and our pro-rata share of $80.0 million of new mortgage debt.  Approximately $2.9 millionand $3.8 million of net assets acquired were allocated to other assets for "above market leases" and other liabilities for "below market leases", respectively. The purchase price for Plaza El Segundo was $192.7 million and our 48.2% ownership interest was funded with $8.5 million of cash and the assumption of our pro-rata share of the existing $175.0 million mortgage debt.  Approximately $7.5 million and $2.3 million of net assets acquired were allocated to other assets for "above market leases" and other liabilities for "below market leases", respectively. The balance sheet at December 31, 2011, has been adjusted to reflect the final purchase price allocation for both properties.

Accounting Policies [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

Our consolidated financial statements include the accounts of the Trust, its corporate subsidiaries, and all entities in which the Trust has a controlling interest or has been determined to be the primary beneficiary of a variable interest entity (“VIE”). The equity interests of other investors are reflected as noncontrolling interests or redeemable noncontrolling interests. All significant intercompany transactions and balances are eliminated in consolidation. We account for our interests in joint ventures, which we do not control, using the equity method of accounting. Certain 2011 amounts have been reclassified to conform to current period presentation.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America, referred to as “GAAP,” requires management to make estimates and assumptions that in certain circumstances affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities, and revenues and expenses. These estimates are prepared using management’s best judgment, after considering past, current and expected events and economic conditions. Actual results could differ from these estimates.

Comprehensive Income

In June 2011, the FASB issued ASU 2011-05, “Comprehensive Income (Topic 220): Presentation of Comprehensive Income.” ASU 2011-05 eliminates the option to present components of other comprehensive income as part of the statement of shareholders’ equity and requires the presentation of components of net income and components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In December 2011, the FASB deferred the requirement to present reclassification adjustments for each component of accumulated other comprehensive income in both net income and other comprehensive income on the face of the financial statements. We adopted the standards effective January 1, 2012 and modified the presentation in our consolidated financial statements accordingly.

The components of comprehensive income are as follows:

	Three Months Ended March 31,
	2012			2011
	(In thousands)
Net income	$	44,122		$	32,384
Other comprehensive income	1,358			—
Comprehensive income	$	45,480		$	32,384
Net income attributable to noncontrolling interests	(1,136		)	(1,198		)
Comprehensive income attributable to the Trust	$	44,344		$	31,186

Other Recently Adopted Accounting Pronouncements

In May 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2011-04, “Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs.” The pronouncement was issued to provide a uniform framework for fair value measurements and related disclosures between U.S. GAAP and International Financial Reporting Standards (“IFRS”). ASU 2011-04 changes certain fair value measurement principles and enhances the disclosure requirements particularly for level 3 fair value measurements. We adopted the standard effective January 1, 2012 and it did not have a significant impact to our consolidated financial statements.

BUSINESS AND ORGANIZATION

BUSINESS AND ORGANIZATION

Federal Realty Investment Trust (the “Trust”) is an equity real estate investment trust (“REIT”) specializing in the ownership, management, and redevelopment of retail and mixed-use properties. Our properties are located primarily in densely populated and affluent communities in strategically selected metropolitan markets in the Mid-Atlantic and Northeast regions of the United States, as well as in California. As of March 31, 2012, we owned or had a majority interest in community and neighborhood shopping centers and mixed-use properties which are operated as 87 predominantly retail real estate projects.

We operate in a manner intended to enable us to qualify as a REIT for federal income tax purposes. A REIT that distributes at least 90% of its taxable income to its shareholders each year and meets certain other conditions is not taxed on that portion of its taxable income which is distributed to its shareholders. Therefore, federal income taxes on our taxable income have been and are generally expected to be immaterial. We are obligated to pay state taxes, generally consisting of franchise or gross receipts taxes in certain states. Such state taxes also have not been material.

Earnings Per Share

Earnings Per Share [Abstract]

EARNINGS PER SHARE

EARNINGS PER SHARE

We have calculated earnings per share (“EPS”) under the two-class method. The two-class method is an earnings allocation methodology whereby EPS for each class of common stock and participating securities is calculated according to dividends declared and participation rights in undistributed earnings. For the three months ended March 31, 2012 and 2011, we had 0.3 million weighted average unvested shares outstanding, which are considered participating securities. Therefore, we have allocated our earnings for basic and diluted EPS between common shares and unvested shares; the portion of earnings allocated to the unvested shares is reflected as “earnings allocated to unvested shares” in the reconciliation below.

In the dilutive EPS calculation, dilutive stock options were calculated using the treasury stock method consistent with prior periods. There were no anti-dilutive stock options for the three months ended March 31, 2012. Approximately 0.1 million stock options have been excluded for the three months ended March 31, 2011 as they were anti-dilutive. The conversions of downREIT operating partnership units and 5.417% Series 1 Cumulative Convertible Preferred Shares are anti-dilutive for all periods presented and accordingly, have been excluded from the weighted average common shares used to compute diluted EPS.

Fair Value Of Financial Instruments

3 Months Ended

Fair Value Disclosures [Abstract]

FAIR VALUE OF FINANCIAL INSTRUMENTS

FAIR VALUE OF FINANCIAL INSTRUMENTS

Except as disclosed below, the carrying amount of our financial instruments approximates their fair value. The fair value of our mortgages payable, notes payable and senior notes and debentures is sensitive to fluctuations in interest rates. Quoted market prices (Level 1) were used to estimate the fair value of our marketable senior notes and debentures and discounted cash flow analysis (Level 2) is generally used to estimate the fair value of our mortgages and notes payable. Considerable judgment is necessary to estimate the fair value of financial instruments. The estimates of fair value presented herein are not necessarily indicative of the amounts that could be realized upon disposition of the financial instruments. A summary of the carrying amount and fair value of our mortgages payable, notes payable and senior notes and debentures is as follows:

	March 31, 2012				December 31, 2011
	Carrying Value		Fair Value		Carrying Value		Fair Value
	(In thousands)
Mortgages and notes payable	$	1,038,982	$	1,091,798	$	1,042,682	$	1,099,273
Senior notes and debentures	$	1,004,584	$	1,094,273	$	1,004,635	$	1,085,309

As of March 31, 2012, we have two interest rate swap agreements with a notional amount of $275.0 million that are measured at fair value on a recurring basis. We assess effectiveness of our cash flow hedges both at inception and on an ongoing basis. The effective portion of changes in fair value of the interest rate swaps associated with our cash flow hedges is recorded in accumulated other comprehensive loss and is subsequently reclassified into interest expense as interest is incurred on the related variable rate debt. Within the next 12 months, we expect to reclassify an estimated $3.9 million as an increase to interest expense. Our cash flow hedges become ineffective if critical terms of the hedging instrument and the debt instrument do not perfectly match such as notional amounts, settlement dates, reset dates, calculation period and LIBOR rate. In addition, we evaluate the default risk of the counterparty by monitoring the credit-worthiness of the counterparty. When ineffectiveness exists, the ineffective portion of changes in fair value of the interest rate swaps associated with our cash flow hedges is recognized in earnings in the period affected. Hedge ineffectiveness did not impact earnings in 2012, and we do not anticipate it will have a significant effect in the future.

The fair values of the interest rate swap agreements are based on the estimated amounts we would receive or pay to terminate the contracts at the reporting date and are determined using interest rate pricing models and interest rate related observable inputs. The fair value of our swaps at March 31, 2012 was a liability of $2.6 million and is included in "accounts payable and accrued expenses" on our consolidated balance sheet. The change in valuation on our interest rate swaps was $1.4 million (including $1.0 million reclassified from other comprehensive income to earnings) for the three months ended March 31, 2012 and is included in "accumulated other comprehensive loss". A summary of our financial liabilities that are measured at fair value on a recurring basis, by level within the fair value hierarchy is as follows:

	March 31, 2012								December 31, 2011

Accounting Policies [Abstract]

Principles of Consolidation

Principles of Consolidation

Our consolidated financial statements include the accounts of the Trust, its corporate subsidiaries, and all entities in which the Trust has a controlling interest or has been determined to be the primary beneficiary of a variable interest entity (“VIE”). The equity interests of other investors are reflected as noncontrolling interests or redeemable noncontrolling interests. All significant intercompany transactions and balances are eliminated in consolidation. We account for our interests in joint ventures, which we do not control, using the equity method of accounting. Certain 2011 amounts have been reclassified to conform to current period presentation.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America, referred to as “GAAP,” requires management to make estimates and assumptions that in certain circumstances affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities, and revenues and expenses. These estimates are prepared using management’s best judgment, after considering past, current and expected events and economic conditions. Actual results could differ from these estimates.

Commitments and Contingencies Disclosure [Abstract]

COMMITMENTS AND CONTINGENCIES

COMMITMENTS AND CONTINGENCIES

We are sometimes involved in lawsuits, warranty claims, and environmental matters arising in the ordinary course of business. Management makes assumptions and estimates concerning the likelihood and amount of any potential loss relating to these matters.

We are currently a party to various legal proceedings. We accrue a liability for litigation if an unfavorable outcome is probable and the amount of loss can be reasonably estimated. If an unfavorable outcome is probable and a reasonable estimate of the loss is a range, we accrue the best estimate within the range; however, if no amount within the range is a better estimate than any other amount, the minimum within the range is accrued. Legal fees related to litigation are expensed as incurred. We do not believe that the ultimate outcome of these matters, either individually or in the aggregate, could have a material adverse effect on our financial position or overall trends in results of operations; however, litigation is subject to inherent uncertainties. Also under our leases, tenants are typically obligated to indemnify us from and against all liabilities, costs and expenses imposed upon or asserted against us (1) as owner of the properties due to certain matters relating to the operation of the properties by the tenant, and (2) where appropriate, due to certain matters relating to the ownership of the properties prior to their acquisition by us.

Under the terms of certain partnership agreements, the partners have the right to exchange their operating partnership units for cash or the same number of our common shares, at our option. A total of 326,140 operating partnership units are outstanding which have a total fair value of $31.6 million, based on our closing stock price on March 31, 2012.

For the three months ended March 31, 2012, we issued 220,792 common shares at a weighted average price per share of $96.58 for net cash proceeds of $21.0 million and paid $0.3 million in commissions related to the sales of these common shares.

REAL ESTATE PARTNERSHIPS

REAL ESTATE PARTNERSHIPS

Federal/Lion Venture LP

We have a joint venture arrangement (the “Partnership”) with affiliates of a discretionary fund created and advised by ING Clarion Partners (“Clarion”). We own 30% of the equity in the Partnership and Clarion owns 70%. We hold a general partnership interest, however, Clarion also holds a general partnership interest and has substantive participating rights. We cannot make significant decisions without Clarion’s approval. Accordingly, we account for our interest in the Partnership using the equity method. As of March 31, 2012, the Partnership owned seven retail real estate properties. We are the manager of the Partnership and its properties, earning fees for acquisitions, dispositions, management, leasing, and financing. Intercompany profit generated from fees is eliminated in consolidation. We also have the opportunity to receive performance-based earnings through our Partnership interest. Accounting policies for the Partnership are similar to accounting policies followed by the Trust. The Partnership is subject to a buy-sell provision which is customary for real estate joint venture agreements and the industry. Either partner may initiate this provision at any time, which could result in either the sale of our interest or the use of available cash or borrowings to acquire Clarion’s interest.

Taurus Newbury Street JV II Limited Partnership

On October 31, 2011, our Newbury Street Partnership sold its entire portfolio of three buildings for $44.0 million.  As part of the sale, we received $34.6 million of the net proceeds which included the repayment of our $11.8 million loans. Due to the timing of receiving financial information from the general partner, our share of earnings was recorded one quarter in arrears. Therefore, we recognized the gain on sale of $11.9 million in the first quarter 2012. The deferred gain was included in "other liabilities and deferred credits" on the balance sheet at December 31, 2011.
