Nature Of Operations [Abstract]
BUSINESS AND ORGANIZATION	BUSINESS AND ORGANIZATION Federal Realty Investment Trust (the “Parent Company” and "Trust") is an equity real estate investment trust (“REIT”). Federal Realty OP LP (the "Operating Partnership") is the entity through which the Parent Company conducts substantially all of its operating and owns all of its assets. The Parent Company owns 100% of the limited liability company interests of, is sole member of, and exercises control over Federal Realty GP LLC (the "General Partner"), which in turn, is the sole general partner of the Operating Partnership. The Parent Company specializes in the ownership, management, and redevelopment of retail and mixed-use properties through the Operating Partnership. Our properties are located primarily in communities where we believe retail demand exceeds supply, in strategically selected metropolitan markets in the Mid-Atlantic and Northeast regions of the United States, California, and South Florida. As of December 31, 2022, we owned or had a majority interest in community and neighborhood shopping centers and mixed-use properties which are operated as 103 predominantly retail real estate projects. We operate in a manner intended to enable the Trust 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.

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation In January 2022, we completed a reorganization into an umbrella partnership real estate investment trust, or "UPREIT." For additional information on our UPREIT reorganization, please see our Current Reports on Form 8-K filed with the SEC on January 3, 2022 and January 5, 2022, as well our 2021 Annual Report on Form 10-K filed on February 10, 2022. Immediately following the reorganization, the Parent Company had the same consolidated assets and liabilities as Federal Realty Investment Trust immediately before the reorganization. The Parent Company exercises exclusive control over the General Partner and does not have assets or liabilities other than its investment in the Operating Partnership. As a result, the UPREIT reorganization represented a merger of entities under common control in accordance with accounting principles generally accepted in the United States ("GAAP"). Accordingly, the accompanying consolidated financial statements including the notes thereto, are presented as if the UPREIT reorganization had occurred at the earliest period presented. Certain 2021, 2020, and 2019 amounts have been reclassified to conform to current period presentation. Principles of Consolidation As discussed in the Explanatory Note, we have combined the Annual Reports on Form 10-K of the Parent Company and the Operating Partnership into this single report. As a result, we present two sets of consolidated financial statements. Both sets of consolidated financial statements include the accounts of the entity, its corporate subsidiaries, and all entities in which it has a controlling interest or has been determined to the primary beneficiary of a variable interest entity (“VIE”). The Parent Company's consolidated financial statements include the accounts of the Operating Partnership and its subsidiaries as the Parent, and through its ownership and control over the General Partner, exercises exclusive control over the Operating Partnership. 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. 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. Revenue Recognition and Accounts Receivable Our leases with our tenants are classified as operating leases. When collection of substantially all lease payments during the lease term is considered probable, the lease qualifies for accrual accounting. Lease payments are recognized on a straight-line basis from the point in time when the tenant controls the space through the term of the related lease. Variable lease payments relating to percentage rent are recognized at the end of the lease year or earlier if we have determined the required sales level is achieved. Real estate tax and other cost reimbursements are recognized on an accrual basis over the periods in which the related expenditures are incurred. Many of our leases contain tenant options that enable the tenant to extend the term of the lease at expiration at pre-established rental rates that often include fixed rent increases, consumer price index adjustments or other market rate adjustments from the prior base rent. For a tenant to terminate its lease agreement prior to the end of the agreed term, we may require that they pay a fee to cancel the lease agreement. Lease termination fees are generally recognized on the termination date if the tenant has relinquished control of the space. When a lease is terminated early but the tenant continues to control the space under a modified lease agreement, the lease termination fee is generally recognized evenly over the remaining term of the modified lease agreement. Lease concessions (unrelated to the COVID-19 pandemic) are evaluated to determine whether the concession represents a modification of the original lease contract. Modifications generally result in a reassessment of the lease term and lease classification, and remeasurement of lease payments received. Remeasured lease payments are recognized on a straight-line basis over the remaining term of the modified lease contract. In April 2020, the Financial Accounting Standards Board ("FASB") issued interpretive guidance relating to the accounting for lease concessions provided as a result of the COVID-19 pandemic that allows entities to treat the concession as if it was a part of the existing contract instead of applying lease modification accounting. This guidance is only applicable to the COVID-19 pandemic related lease concessions that do not result in a substantial increase in the rights of the lessor or the obligations of the lessee. We have elected this option relating to qualifying rent deferral and rent abatement agreements. For qualifying lease modifications with rent deferrals, this results in no change to our revenue recognition but an increase in the lease receivable balance until the deferred rent has been repaid. For qualifying lease modifications that include rent abatement concessions, this results in a direct reduction of rental income in the current period. As of December 31, 2022, we executed rent deferral agreements related to the COVID-19 pandemic representing approximately $48 million of rent. We have subsequently collected approximately $35 million of those amounts previously deferred. As of December 31, 2022, we have entered into rent abatement agreements related to the COVID-19 pandemic totaling $4 million, $26 million, and $48 million of rents due in 2022, 2021, and 2020 respectively. When collection of substantially all lease payments during the lease term is not considered probable, total lease revenue is limited to the lesser of revenue recognized under accrual accounting or cash received. Determining the probability of collection of substantially all lease payments during a lease term requires significant judgment. This determination is impacted by numerous factors including our assessment of the tenant’s credit worthiness, economic conditions, tenant sales productivity in that location, historical experience with the tenant and tenants operating in the same industry, future prospects for the tenant and the industry in which it operates, and the length of the lease term. If leases currently classified as probable are subsequently reclassified as not probable, any outstanding lease receivables (including straight-line rent receivables) would be written-off with a corresponding decrease in rental income. If leases currently classified as not probable are subsequently changed to probable, any lease receivables (including straight-line rent receivables) are re-instated with a corresponding increase to rental income. Our collection of rents has continued to improve from the initial impacts of COVID-19, including collecting rents related to prior periods. As a result, our collectibility related adjustments for the year ended December 31, 2022 resulted in an increase to rental income of $4.1 million, as compared to a $24.0 million and $106.6 million decrease to rental income during the years ended December 31, 2021 and 2020, respectively, which reflected lower levels of cash collections and elevated levels of rent abatements and disputes directly related to COVID-19. This includes changes in our collectibility assessments from probable to not probable, disputed rents, and any rent abatements directly related to COVID-19. As of December 31, 2022 and 2021, the revenue from approximately 31% and 34% of our tenants (based on total commercial leases), respectively, is being recognized on a cash basis. As of December 31, 2022 and 2021, our straight-line rent receivables balance was $126.6 million and $110.7 million, respectively, and is included in "accounts and notes receivable, net" on our consolidated balance sheet. Other revenue recognition policies Sales of real estate are recognized upon the transfer of control, which usually occurs when the real estate is legally sold. When we enter into a transaction to sell a property or a portion of a property, we evaluate the recognition of the sale under ASC 610-20, "Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets." In accordance with ASC 610-20, we apply the guidance in ASC 606, "Revenue from Contracts with Customers," to determine whether and when control transfers and how to measure the associated gain or loss. We determine the transaction price based on the consideration we expect to receive. Variable consideration is included in the transaction price to the extent it is probable that a significant reversal of a gain recognized will not occur. We analyze the risk of a significant gain reversal and if necessary limit the amount of variable consideration recognized in order to mitigate this risk. The estimation of variable consideration requires us to make assumptions and apply significant judgment. Real Estate Land, buildings and improvements are recorded at cost. Depreciation is computed using the straight-line method. Estimated useful lives range generally from 35 years to a maximum of 50 years on buildings and major improvements. Minor improvements, furniture and equipment are capitalized and depreciated over useful lives ranging from 2 to 20 years. Maintenance and repairs that do not improve or extend the useful lives of the related assets are charged to operations as incurred. Tenant improvements are capitalized and depreciated over the life of the related lease or their estimated useful life, whichever is shorter. If a tenant vacates its space prior to contractual termination of its lease, the undepreciated balance of any tenant improvements are written off if they are replaced or have no future value. In 2022, 2021 and 2020, real estate depreciation expense was $265.7 million, $245.1 million and $227.9 million, respectively, including amounts from real estate sold. Our methodology of allocating the cost of acquisitions to assets acquired and liabilities assumed is based on estimated fair values, replacement cost and/or appraised values. When we acquire operating real estate properties, the purchase price is allocated to land, building, improvements, leasing costs, intangibles such as acquired leases, assumed debt, if any, and to current assets acquired and current liabilities assumed, if any. The value allocated to acquired leases is amortized over the related lease term and reflected as rental income in the consolidated statements of comprehensive income. We consider qualitative and quantitative factors in evaluating the likelihood of a tenant exercising a below market renewal option and include such renewal options in the calculation of acquired lease value when we consider these to be bargain renewal options. If the value of below market lease intangibles includes renewal option periods, we include such renewal periods in the amortization period utilized. If a tenant vacates its space prior to contractual termination of its lease, the unamortized balance of any acquired lease value is written off to rental income. Transaction costs related to asset acquisitions, such as broker fees, transfer taxes, legal, accounting, valuation, and other professional and consulting fees, are capitalized as part of the acquisition cost. The acquisition of an operating shopping center typically qualifies as an asset acquisition. We capitalize certain costs related to the development and redevelopment of real estate including pre-construction costs, real estate taxes, insurance, construction costs and salaries and related costs of personnel directly involved, are capitalized. Additionally, we capitalize interest costs related to development and redevelopment activities. Capitalization of these costs begin when the activities and related expenditures commence and cease when the project is substantially complete and ready for its intended use at which time the project is placed in service and depreciation commences. Additionally, we make estimates as to the probability of certain development and redevelopment projects being completed. If we determine the development or redevelopment is no longer probable of completion, we expense all capitalized costs which are not recoverable. Long-Lived Assets and Impairment There are estimates and assumptions made by management in preparing the consolidated financial statements for which the actual results will be determined over long periods of time. This includes the recoverability of long-lived assets, including our properties that have been acquired or redeveloped and our investment in certain joint ventures. Management’s evaluation of impairment includes review for possible indicators of impairment as well as, in certain circumstances, undiscounted and discounted cash flow analysis. Since most of our investments in real estate are wholly-owned or controlled assets which are held for use, a property with impairment indicators is first tested for impairment by comparing the undiscounted cash flows, including residual value, to the current net book value of the property. If the undiscounted cash flows are less than the net book value, the property is written down to expected fair value. The calculation of both discounted and undiscounted cash flows requires management to make estimates of future cash flows including revenues, operating expenses, required maintenance and development expenditures, market conditions, demand for space by tenants and rental rates over long periods. Because our properties typically have a long life, the assumptions used to estimate the future recoverability of book value requires significant management judgment. Actual results could be significantly different from the estimates. These estimates have a direct impact on net income, because recording an impairment charge results in a negative adjustment to net income. Cash and Cash Equivalents We define cash and cash equivalents as cash on hand, demand deposits with financial institutions and short term liquid investments with an initial maturity, when purchased, under three months. Cash balances in individual banks may exceed the federally insured limit by the Federal Deposit Insurance Corporation (the “FDIC”). At December 31, 2022, we had $113.2 million in excess of the FDIC insured limit. Prepaid Expenses and Other Assets Prepaid expenses and other assets consist primarily of lease costs, prepaid property taxes and acquired above market leases. Capitalized lease costs are incremental direct costs incurred which were essential to originate a successful leasing arrangement and would not have been incurred had the leasing transaction not taken place. These costs include third party commissions related to obtaining a lease. Capitalized lease costs are amortized over the initial life of the related lease which generally ranges from three Debt Issuance Costs Costs related to the issuance of debt instruments are deferred and are amortized as interest expense over the estimated life of the related issue using the straight-line method which approximates the effective interest method. If a debt instrument is paid off prior to its original maturity date, the unamortized balance of debt issuance costs are written off to interest expense or, if significant, included in “early extinguishment of debt.” Debt issuance costs related to our revolving credit facility are classified as an asset and are included in "prepaid expenses and other assets" in our consolidated balance sheets. All other debt issuance costs are presented as a direct deduction from the carrying amount of the debt liability. Derivative Instruments 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. Interest rate swaps associated with cash flow hedges are recorded at fair value on a recurring basis. Effectiveness of cash flow hedges is assessed both at inception and on an ongoing basis. The effective portion of changes in fair value of the interest rate swaps associated with cash flow hedges is recorded in other comprehensive income (loss) which is included in accumulated other comprehensive income (loss) on the balance sheet and statement of shareholders' equity. 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, the default risk of the counterparty is evaluated by monitoring the credit worthiness of the counterparty which includes reviewing debt ratings and financial performance. If a cash flow hedge is deemed ineffective, the ineffective portion of changes in fair value of the interest rate swaps associated with cash flow hedges is recognized in earnings in the period affected. At December 31, 2022, we have two interest rate swap agreements that effectively fix the interest rate on a mortgage payable associated with our Hoboken property at 3.67%. Both swaps were designated and qualify for cash flow hedge accounting. As of December 31, 2022, our Assembly Row hotel joint venture is a party to two interest rate swap agreements that effectively fix the interest rate on the joint venture's mortgage debt at 5.206%. Both swaps were designated and qualify as cash flow hedges. Hedge ineffectiveness has not impacted earnings in 2022, 2021 and 2020. Mortgage Notes Receivable We have invested in certain mortgage loans that, because of their nature, qualify as loan receivables. At the time of investment, we did not intend for the arrangement to be anything other than a financing and did not contemplate a real estate investment. We evaluate each investment to determine whether the loan arrangement qualifies as a loan, joint venture or real estate investment and the appropriate accounting thereon. Such determination affects our balance sheet classification of these investments and the recognition of interest income derived therefrom. Mortgage notes receivable are recorded at cost, net of any valuation adjustments. Effective January 1, 2020, (upon the adoption of ASU 2016-13, "Financial Instruments - Credit Losses," as amended and interpreted), we account for mortgage notes receivable using the "expected credit loss" model, and accordingly impairment losses are estimated and recorded for the entire life of the loan. Prior to the implementation of ASC 326, we recognized impairment losses as incurred. Interest income is accrued as earned. Mortgage notes receivable are considered past due based on the contractual terms of the note agreement. On a quarterly basis, we evaluate the collectability of each mortgage note receivable and update our expected credit loss model based on various factors which may include payment history, expected fair value of the collateral securing the loan, internal and external credit information and/or economic trends. A loan is considered impaired when it is probable that we will be unable to collect all amounts due under the existing contractual terms. When a loan is considered impaired, the amount of the loss accrual is calculated by comparing the carrying amount of the mortgage note receivable to the present value of expected future cash flows. As our loans are collateralized by mortgages, these loans have risk characteristics similar to the risks in owning commercial real estate. At December 31, 2022, we had three mortgage notes receivable with an aggregate carrying amount, net of valuation adjustments of $9.5 million, and a weighted average interest rate of 10.9%. Share Based Compensation We grant share based compensation awards to employees and trustees typically in the form of restricted common shares, common shares, and options. We measure share based compensation expense based on the grant date fair value of the award and recognize the expense ratably over the requisite service period, which is typically the vesting period. See Note 12 for further discussion regarding our share based compensation plans and policies. Variable Interest Entities Certain entities that do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties or in which equity investors do not have the characteristics of a controlling financial interest qualify as VIEs. VIEs are required to be consolidated by their primary beneficiary. The primary beneficiary of a VIE has both the power to direct the activities that most significantly impact economic performance of the VIE and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. Our equity method investments in the Assembly Row hotel joint venture, the La Alameda shopping center, the Chandler Festival and Chandler Gateway shopping centers, and our mortgage notes receivable are considered variable interests in a VIE (see Note 3 to the consolidated financial statements for additional information on the Chandler Festival and Chandler Gateway shopping centers). As we do not control the activities that most significantly impact the economic performance of our equity method joint ventures or the borrower entities related to our mortgage notes receivable, we are not the primary beneficiary and do not consolidate. As of December 31, 2022 and 2021, our investment in the equity method joint ventures and maximum exposure to loss was $34.0 million and $8.9 million, respectively. As of December 31, 2022 and 2021, our investment in mortgage notes receivable and maximum exposure to loss was $9.5 million for both periods. We also own a 77.7% tenancy in common ("TIC") interest in Escondido Promenade which is recorded as an equity method investment and included in investments in partnerships" on our December 31, 2022 consolidated balance sheets. Our TIC interest in Escondido Promenade is not considered a variable interest in a variable interest entity. See Note 3 to the consolidated financial statements for additional information. In addition, we have 19 entities that meet the criteria of a VIE in which we hold a variable interest. For each of these entities, we control the significant operating decisions and consequently have the power to direct the activities that most significantly impact the economic performance of the entities. As we also have the obligation to absorb the majority of the losses and/or the right to receive a majority of the benefits for each of these entities, all are consolidated in our financial statements. Net real estate assets related to VIEs included in our consolidated balance sheets were approximately $1.6 billion and $1.8 billion as of December 31, 2022 and 2021, respectively, and mortgages related to VIEs included in our consolidated balance sheets were approximately $191.8 million and $335.3 million, as of December 31, 2022 and 2021, respectively. Redeemable Noncontrolling Interests We have certain noncontrolling interests that are redeemable for cash upon the occurrence of an event that is not solely in our control and therefore are classified outside of permanent equity. We adjust the carrying amounts of these noncontrolling interests that are currently redeemable to redemption value at the balance sheet date. Adjustments to the carrying amount to reflect changes in redemption value are recorded as adjustments to additional paid-in capital in shareholders' equity. These amounts are classified within the mezzanine section of the consolidated balance sheets. The following table provides a rollforward of the redeemable noncontrolling interests: Year Ended December 31, 2022 2021 (In thousands) Beginning balance $ 213,708 $ 137,720 Net income 6,613 4,296 Contributions 2,111 74,530 Other comprehensive income - change in value of interest rate swaps 765 320 Distributions & redemptions (32,445) (5,268) Change in redemption value (12,382) 2,110 Ending balance $ 178,370 $ 213,708 On July 13, 2022, we acquired the 21.8% redeemable noncontrolling interest in the partnership that owns our Plaza El Segundo shopping center for $23.6 million, bringing our ownership interest to 100%. Leases We have ground leases at 11 properties which are accounted for as operating leases. The operating lease right of use ("ROU") assets and related liabilities are shown separately on the face of our consolidated balance sheet and reflect the present value of the minimum lease payments. A key input in the calculation is the discount rate. As the rate implied in the lease agreements is not readily determinable, we utilize our incremental borrowing rate that corresponds to the remaining term of the lease, our credit spread, and an adjustment to reflect the collateralized payment terms present in the lease. Our operating lease agreements may include options to extend the lease term or terminate it early. We include options to extend or terminate leases in the ROU operating lease asset and liability when it is reasonably certain we will exercise these options. Operating lease expense is recognized on a straight-line basis over the non-cancellable lease term and is included in rental expenses in our consolidated statements of operations. We do not record an ROU asset or lease liability for leases with terms of less than 12 months. Income Taxes 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. We have elected to treat certain of our subsidiaries as taxable REIT subsidiaries, which we refer to as a TRS. In general, a TRS may engage in any real estate business and certain non-real estate businesses, subject to certain limitations under the Internal Revenue Code of 1986, as amended (the “Code”). A TRS is subject to federal and state income taxes. Our TRS activities have not been material. With few exceptions, we are no longer subject to U.S. federal, state, and local tax examinations by tax authorities for years before 2018. As of December 31, 2022 and 2021, we had no material unrecognized tax benefits. While we currently have no material unrecognized tax benefits, as a policy, we recognize penalties and interest accrued related to unrecognized tax benefits as income tax expense. Segment Information Our primary business is the ownership, management, and redevelopment of retail and mixed-use properties. We review operating and financial information for each property on an individual basis and therefore, each property represents an individual operating segment. We evaluate financial performance using property operating income, which consists of rental income, and mortgage interest income, less rental expenses and real estate taxes. No individual commercial or residential property constitutes more than 10% of our revenues or property operating income and we have no operations outside of the United States of America. Therefore, we have aggregated our properties into one reportable segment as the properties share similar long-term economic characteristics and have other similarities including the fact that they are operated using consistent business strategies, are typically located in major metropolitan areas, and have similar tenant mixes. Forward Equity Sales Our at-the-market (“ATM”) equity program allows shares to be sold through forward sales contracts. Our forward sales contracts currently meet all the conditions for equity classification; and therefore, we record common stock on the settlement date at the purchase price contemplated by the contract. Furthermore, we consider the potential dilution resulting from forward sales contracts in our earnings per share calculations. We use the treasury method to determine the dilution, if any, from the forward sales contracts during the period of time prior to settlement. See Note 8 to the consolidated financial statements for details of our forward sales transactions. Recent Accounting Pronouncements Standard Description Effect on the financial statements or significant matters Adopted on January 1, 2022: ASU 2020-06, August 2020, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity This ASU simplifies the accounting for convertible instruments by removing the requirements to separately present certain conversion features in equity, simplifying the settlement assessment that entities are required to perform to determine whether a contract qualifies for equity classification, and generally requiring the use of the if-converted method for all convertible instruments in the diluted EPS calculation and include the effect of potential share settlement (if the effect is more dilutive). The guidance is effective for annual period beginning after December 15, 2021, and interim periods therein. The adoption of this standard did not have an impact to our consolidated financial statements. ASU 2021-05, July 2021, Lessors - Certain Leases with Variable Lease Payments (Topic 842) This ASU amends the lessor lease classification in ASC 842 for leases that include variable lease payments that are not based on an index or rate. Under the amended guidance, lessors will classify a lease with variable payments that do not depend on an index or rate as an operating lease if the lease would have been classified as a sales-type lease or a direct financing lease under the previous ASU 842 classification criteria, and sales-type or direct financing lease classification would result in a Day 1 loss. This guidance is effective for annual periods beginning after December 15, 2021, and interim periods therein. The adoption of this standard did not have an impact to our consolidated financial statements. Issued in 2022: ASU 2022-03, June 2022, Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions (Topic 820) This ASU clarifies that contractual sale restrictions are not considered in measuring the fair value of equity securities, and requires specific disclosures for all entities with equity securities subject to a contractual sale restriction including (1) the fair value of such equity securities reflected in the balance sheet, (2) the nature and remaining duration of the corresponding restrictions, and (3) any circumstances that could cause a lapse in the restrictions. In addition, the ASU prohibits an entity from recognizing a contractual sale as a separate unit of account. This guidance is effective in fiscal years beginning after December 15, 2023, and interim periods within those fiscal years, with early adoption permitted. We are assessing the impact of this ASU on OP units issued as consideration in future acquisitions.

(2) This building is adjacent to, and will be operated as part of our Hilton Village property. The land is controlled under a long-term ground lease that expires on September 30, 2075, for which we have recorded a $6.5 million "operating lease right of use asset" (net of a $0.8 million above market liability) and a $7.3 million "operating lease liability." Approximately $8.9 million of net assets acquired were allocated to other assets for "acquired lease costs" and $0.1 million of net assets acquired were allocated to other liabilities for "below market leases." (3) Approximately $16.3 million and $1.6 million of net assets acquired were allocated to other assets for "acquired lease costs" and "above market leases," respectively, and $18.4 million of net assets acquired were allocated to other liabilities for "below market leases." (4) This property, that we own a 90% ownership interest in, was acquired through our Hoboken joint venture, and is in the beginning stages of redevelopment. On October 6, 2022, we acquired a 47.5% net interest in an unconsolidated joint venture that owns two shopping centers for a combined price of $58.9 million. On the date of acquisition, the properties had combined mortgage debt of $76.1 million, of which, our share is approximately $36.2 million. Approximately $8.0 million and $2.0 million of net assets acquired were allocated to other assets for "acquired lease costs" and "above market leases," respectively, and $17.1 million of net assets acquired were allocated to other liabilities for "below market leases." Additional information on the properties is listed below: Property City/State Gross Leasable Area (GLA) Purchase Price (in square feet) (in millions) Chandler Festival Chandler, Arizona 355,000 $ 40.8 Chandler Gateway Chandler, Arizona 262,000 $ 18.1 2022 Property Dispositions During the year ended December 31, 2022, we sold two residential properties (one included an adjacent retail pad), one retail property, one parcel of land, and one portion of a property for sales prices totaling $136.2 million, resulting in net gains totaling approximately $84.1 million. Other Transaction On August 25, 2022, we entered into a tenancy in common ("TIC") agreement with our partner in the partnership that owned Escondido Promenade. As a result, the Company owns a 77.7% TIC interest, and our former partner owns the remaining 22.3% interest. While the Company controlled and consolidated Escondido Promenade under the previous partnership arrangement, control is shared under the TIC agreement. The transaction is considered a transfer of our previous controlling partner interest in exchange for a non-controlling TIC interest. Accordingly, we deconsolidated the entity and recorded our TIC interest at fair value as an equity method investment. We recognized a $70.4 million "gain on deconsolidation of VIE" on our consolidated statements of operations, which is the difference between the net carrying value of the deconsolidated entity and the fair value of our TIC interest. As of August 25, 2022, the fair value of our investment in the entity was $110.0 million, and is included in "investment in partnerships" on our consolidated balance sheet as of December 31, 2022. As a part of this transaction, we made a $3.5 million loan to our co-owner, which is included in "accounts and notes receivable, net" on our consolidated balance sheet at December 31, 2022. In addition, we entered into a purchase option agreement to acquire the TIC interest from our co-owner, which was secured through an option payment of $1.5 million, and allows us to exercise our option at any time between February 1, 2023 and March 15, 2023. 2021 Property Acquisitions On January 4, 2021, we acquired our partner's 20% interest in our joint venture arrangement related to the Pike & Rose hotel for $2.3 million, and repaid the $31.5 million mortgage loan encumbering the hotel. As a result of the transaction, we gained control of the hotel, and effective January 4, 2021, we have consolidated this asset. We also recognized a gain on acquisition of the controlling interest of $2.1 million related to the difference between the carrying value and fair value of the previously held equity interest. On February 22, 2021, we acquired the fee interest at our Mount Vernon Plaza property in Alexandria, Virginia for $5.6 million. As a result of this transaction, the "operating lease right of use assets" and "operating lease liabilities" on our consolidated balance sheet decreased by $9.8 million. We now own the entire fee interest on this property. During the year ended December 31, 2021, we acquired the following properties: Date Acquired Property City/State Gross Leasable Area (GLA) Ownership % Gross Value (in square feet) (in millions) April 30, 2021 Chesterbrook (1) McLean, Virginia 90,000 80 % $ 32.1 (2) June 1, 2021 Grossmont Center (1) La Mesa, California 933,000 60 % $ 175.0 (3) June 14, 2021 Camelback Colonnade (1) Phoenix, Arizona 642,000 98 % $ 162.5 (4) June 14, 2021 Hilton Village (1) Scottsdale, Arizona 93,000 98 % $ 37.5 (5) September 2, 2021 Twinbrooke Shopping Centre Fairfax, Virginia 106,000 100 % $ 33.8 (6) (1) These acquisitions were completed through newly formed joint ventures, for which we own the controlling interest listed above, and therefore, these properties are consolidated in our financial statements. (2) Approximately $1.9 million and $0.6 million of net assets acquired were allocated to other assets for "acquired lease costs" and "above market leases," respectively, and $8.0 million of net assets acquired were allocated to other liabilities for "below market leases." (3) Approximately $12.3 million and $2.6 million of net assets acquired were allocated to other assets for "acquired lease costs" and "above market leases," respectively, and $14.7 million of net assets acquired were allocated to other liabilities for "below market leases." (4) Approximately $11.6 million of net assets acquired were allocated to other assets for "acquired lease costs" and $28.3 million were allocated to other liabilities for "below market leases." (5) The land is controlled under a long-term ground lease that expires on December 31, 2076, for which we have recorded a $10.4 million "operating lease right of use asset" (net of a $1.3 million above market liability) and an $11.6 million "operating lease liability." Approximately $2.7 million and $1.1 million of net assets acquired were allocated to other assets for "acquired lease costs" and "above market leases," respectively, and $3.6 million were allocated to other liabilities for "below market leases." (6) Approximately $1.2 million and $0.3 million of net assets acquired were allocated to other assets for "acquired lease costs" and "above market leases," respectively, and $2.7 million of net assets acquired were allocated to other liabilities for "below market leases." 2021 Property Dispositions During the year ended December 31, 2021, we sold two properties and a portion of three properties for a total sales price of $141.6 million, which resulted in a net gain of $88.3 million.

(2) The interest rates on these mortgages range from 3.91% to 5.00%. (3) Our revolving credit facility SOFR loans bear interest at Daily Simple SOFR or Term SOFR as defined in the credit agreement and our term loan bears interest at Term SOFR, plus 0.10%, plus a spread, based on our current credit rating. (4) The maximum amount drawn under our revolving credit facility during the year ended December 31, 2022 was $330.0 million and the weighted average interest rate on borrowings under our revolving credit facility, before amortization of debt fees, was 3.2%. (5) The Operating Partnership is the obligor under our revolving credit facility, term loan, and senior notes and debentures. (6) The interest rates on these notes payable range from 3.00% to 11.31%. On June 29, 2022, we repaid the $16.1 million mortgage loan on one of the buildings at our Hoboken property, at par. On October 5, 2022, we amended our revolving credit facility, increasing the borrowing capacity from $1.0 billion to $1.25 billion, extending the maturity date to April 5, 2027, plus two six-month extension options, transitioning the interest rate provisions from LIBOR to the secured overnight financing rate ("SOFR"), and adjusting the spread for SOFR based loans. Our SOFR based loans bear interest at Daily Simple SOFR or Term SOFR as defined in the credit agreement plus 0.10% plus a spread, based on our credit rating. The current spread is 77.5 basis points. In addition, we have an option (subject to bank approval) to increase the credit facility through an accordion feature to $1.75 billion. During 2022, 2021 and 2020, the maximum amount of borrowings outstanding under our revolving credit facility was $330.0 million, $150.0 million and $990.0 million, respectively. The weighted average amount of borrowings outstanding was $80.3 million, $19.6 million and $138.5 million, respectively, and the weighted average interest rate, before amortization of debt fees, was 3.2%, 0.9% and 1.5%, respectively. The revolving credit facility requires an annual facility fee which is $1.9 million under the amended credit agreement. At December 31, 2022 and December 31, 2021, our revolving credit facility had no balance outstanding. On October 5, 2022, we also amended our unsecured term loan and borrowed an additional $300.0 million, bringing the total outstanding to $600.0 million. The term loan amendment also transitioned the interest rate provisions from LIBOR to SOFR. This SOFR based loan bears interest at Term SOFR as defined in the agreement, plus 0.10%, plus a 85 basis point spread, based on our current credit rating. The net proceeds from the term loan after underwriting fees and other costs were $298.5 million, and were used to repay the $267.0 million outstanding balance on the revolving credit facility and for general corporate purposes. 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 December 31, 2022, we were in compliance with all default related debt covenants. Scheduled principal payments on mortgages payable, notes payable, senior notes and debentures as of December 31, 2022 are as follows: Mortgages Notes Senior Notes and Total (In thousands) Year ending December 31, 2023 $ 3,138 $ 755 $ 275,000 $ 278,893 2024 3,299 600,671 (1) 600,000 1,203,970 2025 47,630 418 — 48,048 2026 26,240 76 429,200 455,516 2027 178,278 37 (2) 515,000 693,315 Thereafter 63,732 1,000 1,600,000 1,664,732 $ 322,317 $ 602,957 $ 3,419,200 $ 4,344,474 (3) _____________________ (1) Our $600.0 million term loan matures on April 16, 2024 plus two one-year extensions, at our option.

Fair Value Disclosures [Abstract]
FAIR VALUE OF FINANCIAL INSTRUMENTS	FAIR VALUE OF FINANCIAL INSTRUMENTS A fair value measurement is based on the assumptions that market participants would use in pricing an asset or liability in an orderly transaction. The hierarchy for inputs used in measuring fair value are as follows: 1. Level 1 Inputs—quoted prices in active markets for identical assets or liabilities 2. Level 2 Inputs—observable inputs other than quoted prices in active markets for identical assets and liabilities 3. Level 3 Inputs—prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement. 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: December 31, 2022 December 31, 2021 Carrying Fair Value Carrying Fair Value (In thousands) Mortgages and notes payable $ 921,692 $ 895,654 $ 641,459 $ 655,864 Senior notes and debentures $ 3,407,701 $ 3,048,456 $ 3,406,088 $ 3,649,776 As of December 31, 2022, we have two interest rate swap agreements with notional amounts of $55.1 million that are measured at fair value on a recurring basis. The interest rate swap agreements fix the interest rate on $55.1 million of mortgage payables at 3.67% through December 15, 2029. 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 December 31, 2022 was an asset of $6.1 million and is included in "prepaid expenses and other assets" on our consolidated balance sheet. During 2022, the value of our interest rate swaps increased $7.7 million (including less than $0.1 million reclassified from other comprehensive income as an increase to interest expense). A summary of our financial assets (liabilities) that are measured at fair value on a recurring basis, by level within the fair value hierarchy is as follows: December 31, 2022 December 31, 2021 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total (In thousands) Interest rate swaps $ — $ 6,144 $ — $ 6,144 $ — $ (1,511) $ — $ (1,511) One of our equity method investees has two interest rate swaps which qualify as cash flow hedges. At December 31, 2022 and December 31, 2021, our share of the change in fair value of the related swaps included in "accumulated other comprehensive income (loss)" was an increase of $0.9 million and $0.7 million, respectively.

Commitments and Contingencies

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. We are self-insured for general liability costs up to predetermined retained amounts per claim, and we believe that we maintain adequate accruals to cover our retained liability. We currently do not maintain third party stop-loss insurance policies to cover liability costs in excess of predetermined retained amounts. Our accrual for self-insurance liability is determined by management and is based on claims filed and an estimate of claims incurred but not yet reported. Management considers a number of factors, including third-party actuarial analysis, previous experience in our portfolio, and future increases in costs of claims, when making these determinations. If our liability costs exceed these accruals, it will reduce our net income. We reserve for estimated losses, if any, associated with warranties given to a buyer at the time real estate is sold or other potential liabilities relating to that sale, taking any insurance policies into account. These warranties may extend up to ten years and require significant judgment. If changes in facts and circumstances indicate that warranty reserves are understated, we will accrue additional reserves at such time a liability has been incurred and the costs can be reasonably estimated. Warranty reserves are released once the legal liability period has expired or all related work has been substantially completed. At December 31, 2022 and 2021, our reserves for general liability costs were $3.3 million and $5.2 million, respectively, and are included in “accounts payable and accrued expenses” in our consolidated balance sheets. Any potential losses which exceed our estimates would result in a decrease in our net income. During 2022 and 2021, we made payments from these reserves of $2.3 million and $1.5 million, respectively. Although we consider the reserve to be adequate, there can be no assurance that the reserve will prove to be adequate over-time to cover losses due to the difference between the assumptions used to estimate the reserve and actual losses. On July 13, 2022, we acquired the 21.8% redeemable noncontrolling interest in the partnership that owns our Plaza El Segundo shopping center for $23.6 million, bringing our ownership interest to 100%. On December 11, 2019, we received proceeds related to the sale under the threat of condemnation at San Antonio Center as discussed in our Annual Report on Form 10-K for the year ended December 31, 2019. We indemnified the condemning authority for all costs incurred related to the condemnation proceedings including any payments required to tenants at the property and recorded a corresponding liability for our estimate of these costs. During 2022, we recorded a net reduction to our liability for condemnation and transaction costs to reflect the impact of a recent tenant settlement agreement and our current estimate of remaining costs. As a result, for the year ended December 31, 2022, we have recognized a gain of $9.3 million, which is included in our consolidated statements of operations. Additionally, during 2022, we incurred $18.0 million of payments to tenants, and consequently, at December 31, 2022, we have a liability of $5.0 million to reflect our estimate of the remaining consideration. At December 31, 2022, we had letters of credit outstanding of approximately $6.7 million. As of December 31, 2022 in connection with capital improvement, development, and redevelopment projects, we have contractual obligations of approximately $262.1 million. We are obligated under operating lease agreements on several shopping centers and one office lease requiring minimum annual payments as follows, as of December 31, 2022: (In thousands) Year ending December 31, 2023 $ 5,775 2024 5,949 2025 5,815 2026 5,451 2027 5,037 Thereafter 198,973 Total future minimum operating lease payments 227,000 Less amount representing interest (149,257) Operating lease liabilities $ 77,743 Future minimum lease payments and their present value for properties under finance leases as of December 31, 2022, are as follows: (In thousands) Year ending December 31, 2023 $ 59,713 2024 713 2025 713 2026 713 2027 748 Thereafter 68,676 Total future minimum finance lease payments 131,276 Less amount representing interest (63,616) Finance lease liabilities $ 67,660 A master lease for Mercer Mall includes a fixed purchase price option for $55 million in 2023. During 2022, we exercised our option to purchase the fee interest, which is expected to close in the second half of 2023. Under the terms of the Congressional Plaza partnership agreement, a minority partner has the right to require us and the other minority partner to purchase its 26.63% interest in Congressional Plaza at the interest’s then-current fair market value. If the other minority partner defaults in their obligation, we must purchase the full interest. Based on management’s current estimate of fair market value as of December 31, 2022, our estimated maximum liability upon exercise of the put option would range from approximately $62 million to $65 million. A master lease for Melville Mall, as amended on October 14, 2021, includes a fixed price put option at any time prior to June 30, 2025, requiring us to purchase Melville Mall for approximately $3.6 million. Additionally, we have the right to purchase Melville Mall in 2026 for approximately $3.6 million. The consideration is net of a contract amendment fee to be paid by the landlord. The other member in The Grove at Shrewsbury and Brook 35 has the right to require us to purchase all of its approximately 4.1% interest in The Grove at Shrewsbury and approximately 6.5% interest in Brook 35 at the interests' then-current fair market value. Based on management's current estimate of fair market value as of December 31, 2022, our estimated maximum liability upon exercise of the put option would range from $6 million to $7 million. Effective September 18, 2023, the other member in Hoboken has the right to require us to purchase all of its 10.0% ownership interest at the interest's then-current fair market value. Based on management's current estimate of fair market value as of December 31, 2022, our estimated maximum liability upon exercise of the put option would range from $8 million to $9 million. Effective June 14, 2026, the other member in Camelback Colonnade and Hilton Village has the right to require us to purchase all of its 2.0% ownership interest at the interest's then-current fair market value. Based on management's current estimate of fair value as of December 31, 2022, our estimated maximum liability upon exercise of the put option would range from $4 million to $5 million. Effective October 6, 2027, the other member in the partnership that owns equity method investments in Chandler Festival and Chandler Gateway has the right to require us to purchase its 2.5% net ownership interest. Based on management's current estimate of fair value as of December 31, 2022, our estimated maximum liability upon exercise of the put option would range from $1 million and $2 million. Effective June 1, 2029, the other member in Grossmont Center has the right to require us to purchase all of its 40.0% ownership interest at the interest's then-current fair market value. Based on management's current estimate of fair value as of December 31, 2022, our estimated maximum liability upon exercise of the put option would range from $68 million to $73 million. 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 644,554 downREIT operating partnership units are outstanding which have a total fair value of $65.1 million, based on our closing stock price on December 31, 2022.

Stockholders' Equity Note [Abstract]
SHAREHOLDERS’ EQUITY	SHAREHOLDERS’ EQUITY We have a Dividend Reinvestment Plan (the “Plan”), whereby shareholders may use their dividends and optional cash payments to purchase shares. In 2022, 2021 and 2020, 19,502 shares, 19,758 shares, and 24,491 shares, respectively, were issued under the Plan. As of December 31, 2022, 2021, and 2020, we had 6,000,000 Depositary Shares outstanding, each representing 1/1000th interest of 5.0% Series C Cumulative Redeemable Preferred Share, par value $0.01 per share ("Series C Preferred Shares"), at the liquidation preference of $25.00 per depositary share (or $25,000 per Series C Preferred share). The Series C Preferred Shares accrue dividends at a rate of 5.0% of the $25,000 liquidation preference per year and are redeemable at our option. Additionally, they are not convertible and holders of these shares generally have no voting rights, unless we fail to pay dividends for six or more quarters. As of December 31, 2022, we had 392,878 shares of 5.417% Series 1 Cumulative Convertible Preferred Shares (“Series 1 Preferred Shares”) outstanding that have a liquidation preference of $25 per share and par value $0.01 per share, and 399,896 shares at December 31, 2021 and 2020. The Series 1 Preferred Shares accrue dividends at a rate of 5.417% per year and are convertible at any time by the holders to our common shares at a conversion rate of $104.69 per share. On June 15, 2022, one of our Series 1 Preferred shareholders converted 7,018 preferred shares to 1,675 common shares. The Series 1 Preferred Shares are also convertible under certain circumstances at our election. The holders of the Series 1 Preferred Shares have no voting rights. On February 14, 2022, we replaced our existing at-the-market (“ATM”) equity program with a new ATM equity program in which we may from time to time offer and sell common shares having an aggregate offering price of up to $500.0 million. Our ATM equity program also allows shares to be sold through forward sales contracts. We intend to use the net proceeds from ATM equity program issuances to fund potential acquisition opportunities, fund our development and redevelopment pipeline, repay indebtedness and/or for general corporate purposes. For the year ended December 31, 2022, we issued 430,473 common shares at a weighted average price per share of $111.49 for net cash proceeds of $47.4 million including paying $0.5 million in commissions and $0.1 million in additional offering expenses related to the sales of these common shares. For the year ended December 31, 2021, we issued 847,471 common shares at a weighted average price per share of $104.19 for net cash proceeds of $87.0 million and paid $0.9 million in commissions and $0.4 million in additional offering expenses related to the sales of these common shares. As of December 31, 2022, we have the remaining capacity to issue up to $452.0 million in common shares under our ATM equity program. During 2021, we entered into forward sales contracts for 2,999,955 common shares under our ATM equity program at a weighted average offering price of $120.22. During 2021, we settled a portion of these forward sales agreements by issuing 796,300 common shares for net proceeds of $85.7 million and during 2022, we settled the remaining forward sales contracts by issuing 2,203,655 common shares for net proceeds of $259.4 million. We have no outstanding forward sales agreements as of December 31, 2022.

SHARE-BASED COMPENSATION PLANS	SHARE-BASED COMPENSATION PLANS A summary of share-based compensation expense included in net income is as follows: Year Ended December 31, 2022 2021 2020 (In thousands) Grants of common shares, restricted stock units, and options $ 15,018 $ 14,434 $ 13,243 Capitalized share-based compensation (1,314) (1,425) (1,319) Share-based compensation expense $ 13,704 $ 13,009 $ 11,924 As of December 31, 2022, we have grants outstanding under two share-based compensation plans. In May 2020, our shareholders approved the 2020 Performance Incentive Plan ("the 2020 Plan"), which authorized the grant of share options, common shares, and other share-based awards for up to 1,750,000 common shares of beneficial interest. Our 2010 Long Term Incentive Plan, as amended (the "2010 Plan”), which expired in May 2020, authorized the grant of share options, common shares and other share-based awards for up to 2,450,000 common shares of beneficial interest. Option awards under the plans are required to have an exercise price at least equal to the closing trading price of our common shares on the date of grant. Options and restricted share awards under the plan generally vest over three ten The fair value of each option award is estimated on the date of grant using the Black-Scholes model. Expected volatilities, term, dividend yields, employee exercises and estimated forfeitures are primarily based on historical data. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant. The fair value of each share award is determined based on the closing trading price of our common shares on the grant date. No options were granted in 2022 and 2020. The following table provides a summary of the assumptions used to value options granted in 2021: Year Ended December 31, 2021 Volatility 29.3 % Expected dividend yield 4.1 % Expected term (in years) 7.5 Risk free interest rate 0.9 % The weighted-average grant-date fair value of options granted in 2021 was $16.40 per share. The following table provides a summary of option activity for 2022: Shares Weighted- Weighted- Aggregate (In years) (In thousands) Outstanding at December 31, 2021 3,658 $ 95.77 Granted — — Exercised (366) 95.77 Forfeited or expired (1,463) 95.77 Outstanding at December 31, 2022 1,829 $ 95.77 8.1 $ 10 Exercisable at December 31, 2022 366 $ 95.77 8.1 $ 2 The following table provides a summary of restricted share activity for 2022: Shares Weighted-Average Unvested at December 31, 2021 288,996 $ 112.29 Granted 116,266 125.34 Vested (119,646) 118.81 Forfeited (5,871) 120.62 Unvested at December 31, 2022 279,745 $ 114.75 The weighted-average grant-date fair value of stock awarded in 2022, 2021 and 2020 was $125.34, $97.46 and $124.55, respectively. The total vesting-date fair value of shares vested during the year ended December 31, 2022, 2021 and 2020, was $14.3 million, $11.0 million and $12.4 million, respectively. On February 10, 2021, 10,441 restricted stock units were awarded to an officer that vest at the end of four years. The final awards earned are based on meeting certain market based performance criteria, and may vary from 0% to 200% of the original award. The weighted-average grant-date fair value of the restricted stock units awarded in 2021 was $97.01.

Savings and Retirement Plans [Abstract]
SAVINGS AND RETIREMENT PLANS	SAVINGS AND RETIREMENT PLANS We have a savings and retirement plan in accordance with the provisions of Section 401(k) of the Code. Generally, employees can elect, at their discretion, to contribute a portion of their compensation up to a maximum of $20,500 for 2022, and 19,500 for 2021 and 2020. Under the plan, we contribute 50% of each employee’s elective deferrals up to 5% of eligible earnings. In addition, we may make discretionary contributions within the limits of deductibility set forth by the Code. Our full-time employees are immediately eligible to become plan participants. Employees are eligible to receive matching contributions immediately on their participation; however, these matching payments will not vest until their third anniversary of employment. Our expense for the years ended December 31, 2022, 2021 and 2020 was approximately $869,000, $816,000 and $813,000, respectively. A non-qualified deferred compensation plan for our officers and certain other employees was established in 1994 that allows the participants to defer a portion of their income. As of December 31, 2022 and 2021, we are liable to participants for approximately $18.0 million and $21.0 million, respectively, under this plan. Although this is an unfunded plan, we have purchased certain investments to match this obligation. Our obligation under this plan and the related investments are both included in the accompanying consolidated financial statements.

Earnings Per Share [Abstract]
EARNINGS PER SHARE	EARNINGS PER SHARE AND UNIT We have calculated earnings per share (“EPS”) and earnings per unit ("EPU") under the two-class method. The two-class method is an earnings allocation methodology whereby EPS and EPU for each class of common stock and partnership units, respectively, and participating securities is calculated according to dividends or distributions declared and participation rights in undistributed earnings. For 2022 and 2021 we had 0.3 million weighted average unvested shares and units outstanding, and for 2020 we had 0.2 million which are considered participating securities. Therefore, we have allocated our earnings for basic and diluted EPS and EPU between common shares and units and unvested shares and units; the portion of earnings allocated to the unvested shares and units is reflected as “earnings allocated to unvested shares” or "earnings allocated to unvested units" in the reconciliation below. The following potentially issuable shares were excluded from the diluted EPS and EPU calculations because their impact is anti-dilutive: • exercise of 682 stock options in 2020, • conversions of downREIT operating partnership units for 2021 and 2020, • and 5.417% Series 1 Cumulative Convertible Preferred Shares and units for 2022, 2021, and 2020, and • the issuance of $1.8 million shares and units issuable under forward sales agreements in 2021. Additionally, 10,441 unvested restricted stock units are excluded from the diluted EPS and EPU calculations as the market based performance criteria in the award has not yet been achieved.

Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation As discussed in the Explanatory Note, we have combined the Annual Reports on Form 10-K of the Parent Company and the Operating Partnership into this single report. As a result, we present two sets of consolidated financial statements. Both sets of consolidated financial statements include the accounts of the entity, its corporate subsidiaries, and all entities in which it has a controlling interest or has been determined to the primary beneficiary of a variable interest entity (“VIE”). The Parent Company's consolidated financial statements include the accounts of the Operating Partnership and its subsidiaries as the Parent, and through its ownership and control over the General Partner, exercises exclusive control over the Operating Partnership. 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.
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
Revenue Recognition and Accounts Receivable	Revenue Recognition and Accounts Receivable Our leases with our tenants are classified as operating leases. When collection of substantially all lease payments during the lease term is considered probable, the lease qualifies for accrual accounting. Lease payments are recognized on a straight-line basis from the point in time when the tenant controls the space through the term of the related lease. Variable lease payments relating to percentage rent are recognized at the end of the lease year or earlier if we have determined the required sales level is achieved. Real estate tax and other cost reimbursements are recognized on an accrual basis over the periods in which the related expenditures are incurred. Many of our leases contain tenant options that enable the tenant to extend the term of the lease at expiration at pre-established rental rates that often include fixed rent increases, consumer price index adjustments or other market rate adjustments from the prior base rent. For a tenant to terminate its lease agreement prior to the end of the agreed term, we may require that they pay a fee to cancel the lease agreement. Lease termination fees are generally recognized on the termination date if the tenant has relinquished control of the space. When a lease is terminated early but the tenant continues to control the space under a modified lease agreement, the lease termination fee is generally recognized evenly over the remaining term of the modified lease agreement. Lease concessions (unrelated to the COVID-19 pandemic) are evaluated to determine whether the concession represents a modification of the original lease contract. Modifications generally result in a reassessment of the lease term and lease classification, and remeasurement of lease payments received. Remeasured lease payments are recognized on a straight-line basis over the remaining term of the modified lease contract. In April 2020, the Financial Accounting Standards Board ("FASB") issued interpretive guidance relating to the accounting for lease concessions provided as a result of the COVID-19 pandemic that allows entities to treat the concession as if it was a part of the existing contract instead of applying lease modification accounting. This guidance is only applicable to the COVID-19 pandemic related lease concessions that do not result in a substantial increase in the rights of the lessor or the obligations of the lessee. We have elected this option relating to qualifying rent deferral and rent abatement agreements. For qualifying lease modifications with rent deferrals, this results in no change to our revenue recognition but an increase in the lease receivable balance until the deferred rent has been repaid. For qualifying lease modifications that include rent abatement concessions, this results in a direct reduction of rental income in the current period. As of December 31, 2022, we executed rent deferral agreements related to the COVID-19 pandemic representing approximately $48 million of rent. We have subsequently collected approximately $35 million of those amounts previously deferred. As of December 31, 2022, we have entered into rent abatement agreements related to the COVID-19 pandemic totaling $4 million, $26 million, and $48 million of rents due in 2022, 2021, and 2020 respectively. When collection of substantially all lease payments during the lease term is not considered probable, total lease revenue is limited to the lesser of revenue recognized under accrual accounting or cash received. Determining the probability of collection of substantially all lease payments during a lease term requires significant judgment. This determination is impacted by numerous factors including our assessment of the tenant’s credit worthiness, economic conditions, tenant sales productivity in that location, historical experience with the tenant and tenants operating in the same industry, future prospects for the tenant and the industry in which it operates, and the length of the lease term. If leases currently classified as probable are subsequently reclassified as not probable, any outstanding lease receivables (including straight-line rent receivables) would be written-off with a corresponding decrease in rental income. If leases currently classified as not probable are subsequently changed to probable, any lease receivables (including straight-line rent receivables) are re-instated with a corresponding increase to rental income. Our collection of rents has continued to improve from the initial impacts of COVID-19, including collecting rents related to prior periods. As a result, our collectibility related adjustments for the year ended December 31, 2022 resulted in an increase to rental income of $4.1 million, as compared to a $24.0 million and $106.6 million decrease to rental income during the years ended December 31, 2021 and 2020, respectively, which reflected lower levels of cash collections and elevated levels of rent abatements and disputes directly related to COVID-19. This includes changes in our collectibility assessments from probable to not probable, disputed rents, and any rent abatements directly related to COVID-19. As of December 31, 2022 and 2021, the revenue from approximately 31% and 34% of our tenants (based on total commercial leases), respectively, is being recognized on a cash basis. As of December 31, 2022 and 2021, our straight-line rent receivables balance was $126.6 million and $110.7 million, respectively, and is included in "accounts and notes receivable, net" on our consolidated balance sheet. Other revenue recognition policies Sales of real estate are recognized upon the transfer of control, which usually occurs when the real estate is legally sold. When we enter into a transaction to sell a property or a portion of a property, we evaluate the recognition of the sale under ASC 610-20, "Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets." In accordance with ASC 610-20, we apply the guidance in ASC 606, "Revenue from Contracts with Customers," to determine whether and when control
Real Estate	Real Estate Land, buildings and improvements are recorded at cost. Depreciation is computed using the straight-line method. Estimated useful lives range generally from 35 years to a maximum of 50 years on buildings and major improvements. Minor improvements, furniture and equipment are capitalized and depreciated over useful lives ranging from 2 to 20 years. Maintenance and repairs that do not improve or extend the useful lives of the related assets are charged to operations as incurred. Tenant improvements are capitalized and depreciated over the life of the related lease or their estimated useful life, whichever is shorter. If a tenant vacates its space prior to contractual termination of its lease, the undepreciated balance of any tenant improvements are written off if they are replaced or have no future value. In 2022, 2021 and 2020, real estate depreciation expense was $265.7 million, $245.1 million and $227.9 million, respectively, including amounts from real estate sold. Our methodology of allocating the cost of acquisitions to assets acquired and liabilities assumed is based on estimated fair values, replacement cost and/or appraised values. When we acquire operating real estate properties, the purchase price is allocated to land, building, improvements, leasing costs, intangibles such as acquired leases, assumed debt, if any, and to current assets acquired and current liabilities assumed, if any. The value allocated to acquired leases is amortized over the related lease term and reflected as rental income in the consolidated statements of comprehensive income. We consider qualitative and quantitative factors in evaluating the likelihood of a tenant exercising a below market renewal option and include such renewal options in the calculation of acquired lease value when we consider these to be bargain renewal options. If the value of below market lease intangibles includes renewal option periods, we include such renewal periods in the amortization period utilized. If a tenant vacates its space prior to contractual termination of its lease, the unamortized balance of any acquired lease value is written off to rental income. Transaction costs related to asset acquisitions, such as broker fees, transfer taxes, legal, accounting, valuation, and other professional and consulting fees, are capitalized as part of the acquisition cost. The acquisition of an operating shopping center typically qualifies as an asset acquisition. We capitalize certain costs related to the development and redevelopment of real estate including pre-construction costs, real estate taxes, insurance, construction costs and salaries and related costs of personnel directly involved, are capitalized. Additionally, we capitalize interest costs related to development and redevelopment activities. Capitalization of these costs begin when the activities and related expenditures commence and cease when the project is substantially complete and ready for its intended use at which time the project is placed in service and depreciation commences. Additionally, we make estimates as to the probability of certain development and redevelopment projects being completed. If we determine the development or redevelopment is no longer probable of completion, we expense all capitalized costs which are not recoverable.
Long Lived Assets and Impairment	Long-Lived Assets and Impairment There are estimates and assumptions made by management in preparing the consolidated financial statements for which the actual results will be determined over long periods of time. This includes the recoverability of long-lived assets, including our properties that have been acquired or redeveloped and our investment in certain joint ventures. Management’s evaluation of impairment includes review for possible indicators of impairment as well as, in certain circumstances, undiscounted and discounted cash flow analysis. Since most of our investments in real estate are wholly-owned or controlled assets which are held for use, a property with impairment indicators is first tested for impairment by comparing the undiscounted cash flows, including residual value, to the current net book value of the property. If the undiscounted cash flows are less than the net book value, the property is written down to expected fair value. The calculation of both discounted and undiscounted cash flows requires management to make estimates of future cash flows including revenues, operating expenses, required maintenance and development expenditures, market conditions, demand for space by tenants and rental rates over long periods. Because our properties typically have a long life, the assumptions used to estimate the future recoverability of book value requires significant management judgment. Actual results could be significantly different from the estimates. These estimates have a direct impact on net income, because recording an impairment charge results in a negative adjustment to net income.
Cash and Cash Equivalents	Cash and Cash Equivalents We define cash and cash equivalents as cash on hand, demand deposits with financial institutions and short term liquid investments with an initial maturity, when purchased, under three months. Cash balances in individual banks may exceed the federally insured limit by the Federal Deposit Insurance Corporation (the “FDIC”). At December 31, 2022, we had $113.2 million in excess of the FDIC insured limit.
Prepaid Expenses and Other Assets	Prepaid Expenses and Other Assets Prepaid expenses and other assets consist primarily of lease costs, prepaid property taxes and acquired above market leases. Capitalized lease costs are incremental direct costs incurred which were essential to originate a successful leasing arrangement and would not have been incurred had the leasing transaction not taken place. These costs include third party commissions related to obtaining a lease. Capitalized lease costs are amortized over the initial life of the related lease which generally ranges from three
Debt Issuance Costs	Debt Issuance Costs Costs related to the issuance of debt instruments are deferred and are amortized as interest expense over the estimated life of the related issue using the straight-line method which approximates the effective interest method. If a debt instrument is paid off prior to its original maturity date, the unamortized balance of debt issuance costs are written off to interest expense or, if significant, included in “early extinguishment of debt.” Debt issuance costs related to our revolving credit facility are classified as an asset and are included in "prepaid expenses and other assets" in our consolidated balance sheets. All other debt issuance costs are presented as a direct deduction from the carrying amount of the debt liability.
Derivative Instruments	Derivative Instruments 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. Interest rate swaps associated with cash flow hedges are recorded at fair value on a recurring basis. Effectiveness of cash flow hedges is assessed both at inception and on an ongoing basis. The effective portion of changes in fair value of the interest rate swaps associated with cash flow hedges is recorded in other comprehensive income (loss) which is included in accumulated other comprehensive income (loss) on the balance sheet and statement of shareholders' equity. 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, the default risk of the counterparty is evaluated by monitoring the credit worthiness of the counterparty which includes reviewing debt ratings and financial performance. If a cash flow hedge is deemed ineffective, the ineffective portion of changes in fair value of the interest rate swaps associated with cash flow hedges is recognized in earnings in the period affected. At December 31, 2022, we have two interest rate swap agreements that effectively fix the interest rate on a mortgage payable associated with our Hoboken property at 3.67%. Both swaps were designated and qualify for cash flow hedge accounting. As of December 31, 2022, our Assembly Row hotel joint venture is a party to two interest rate swap agreements that effectively fix the interest rate on the joint venture's mortgage debt at 5.206%. Both swaps were designated and qualify as cash flow hedges. Hedge ineffectiveness has not impacted earnings in 2022, 2021 and 2020.
Mortgage Notes Receivable	Mortgage Notes Receivable We have invested in certain mortgage loans that, because of their nature, qualify as loan receivables. At the time of investment, we did not intend for the arrangement to be anything other than a financing and did not contemplate a real estate investment. We evaluate each investment to determine whether the loan arrangement qualifies as a loan, joint venture or real estate investment and the appropriate accounting thereon. Such determination affects our balance sheet classification of these investments and the recognition of interest income derived therefrom. Mortgage notes receivable are recorded at cost, net of any valuation adjustments. Effective January 1, 2020, (upon the adoption of ASU 2016-13, "Financial Instruments - Credit Losses," as amended and interpreted), we account for mortgage notes receivable using the "expected credit loss" model, and accordingly impairment losses are estimated and recorded for the entire
Share Based Compensation	Share Based Compensation We grant share based compensation awards to employees and trustees typically in the form of restricted common shares, common shares, and options. We measure share based compensation expense based on the grant date fair value of the award and recognize the expense ratably over the requisite service period, which is typically the vesting period. See Note 12 for further discussion regarding our share based compensation plans and policies.
Variable Interest Entities	Variable Interest Entities Certain entities that do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties or in which equity investors do not have the characteristics of a controlling financial interest qualify as VIEs. VIEs are required to be consolidated by their primary beneficiary. The primary beneficiary of a VIE has both the power to direct the activities that most significantly impact economic performance of the VIE and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. Our equity method investments in the Assembly Row hotel joint venture, the La Alameda shopping center, the Chandler Festival and Chandler Gateway shopping centers, and our mortgage notes receivable are considered variable interests in a VIE (see Note 3 to the consolidated financial statements for additional information on the Chandler Festival and Chandler Gateway shopping centers). As we do not control the activities that most significantly impact the economic performance of our equity method joint ventures or the borrower entities related to our mortgage notes receivable, we are not the primary beneficiary and do not consolidate. As of December 31, 2022 and 2021, our investment in the equity method joint ventures and maximum exposure to loss was $34.0 million and $8.9 million, respectively. As of December 31, 2022 and 2021, our investment in mortgage notes receivable and maximum exposure to loss was $9.5 million for both periods. We also own a 77.7% tenancy in common ("TIC") interest in Escondido Promenade which is recorded as an equity method investment and included in investments in partnerships" on our December 31, 2022 consolidated balance sheets. Our TIC interest in Escondido Promenade is not considered a variable interest in a variable interest entity. See Note 3 to the consolidated financial statements for additional information. In addition, we have 19 entities that meet the criteria of a VIE in which we hold a variable interest. For each of these entities, we control the significant operating decisions and consequently have the power to direct the activities that most significantly impact the economic performance of the entities. As we also have the obligation to absorb the majority of the losses and/or the right to receive a majority of the benefits for each of these entities, all are consolidated in our financial statements. Net real estate assets related to VIEs included in our consolidated balance sheets were approximately $1.6 billion and $1.8 billion as of December 31, 2022 and 2021, respectively, and mortgages related to VIEs included in our consolidated balance sheets were approximately $191.8 million and $335.3 million, as of December 31, 2022 and 2021, respectively.
Redeemable Noncontrolling Interests	Redeemable Noncontrolling Interests We have certain noncontrolling interests that are redeemable for cash upon the occurrence of an event that is not solely in our control and therefore are classified outside of permanent equity. We adjust the carrying amounts of these noncontrolling interests that are currently redeemable to redemption value at the balance sheet date. Adjustments to the carrying amount to reflect changes in redemption value are recorded as adjustments to additional paid-in capital in shareholders' equity. These amounts are classified within the mezzanine section of the consolidated balance sheets. The following table provides a rollforward of the redeemable noncontrolling interests: Year Ended December 31, 2022 2021 (In thousands) Beginning balance $ 213,708 $ 137,720 Net income 6,613 4,296 Contributions 2,111 74,530 Other comprehensive income - change in value of interest rate swaps 765 320 Distributions & redemptions (32,445) (5,268) Change in redemption value (12,382) 2,110 Ending balance $ 178,370 $ 213,708 On July 13, 2022, we acquired the 21.8% redeemable noncontrolling interest in the partnership that owns our Plaza El Segundo shopping center for $23.6 million, bringing our ownership interest to 100%.
Leases	LeasesWe have ground leases at 11 properties which are accounted for as operating leases. The operating lease right of use ("ROU") assets and related liabilities are shown separately on the face of our consolidated balance sheet and reflect the present value of the minimum lease payments. A key input in the calculation is the discount rate. As the rate implied in the lease agreements is not readily determinable, we utilize our incremental borrowing rate that corresponds to the remaining term of the lease, our credit spread, and an adjustment to reflect the collateralized payment terms present in the lease. Our operating lease agreements may include options to extend the lease term or terminate it early. We include options to extend or terminate leases in the ROU operating lease asset and liability when it is reasonably certain we will exercise these options. Operating lease expense is recognized on a straight-line basis over the non-cancellable lease term and is included in rental expenses in our consolidated statements of operations. We do not record an ROU asset or lease liability for leases with terms of less than 12 months.
Income Taxes	Income Taxes 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. We have elected to treat certain of our subsidiaries as taxable REIT subsidiaries, which we refer to as a TRS. In general, a TRS may engage in any real estate business and certain non-real estate businesses, subject to certain limitations under the Internal Revenue Code of 1986, as amended (the “Code”). A TRS is subject to federal and state income taxes. Our TRS activities have not been material. With few exceptions, we are no longer subject to U.S. federal, state, and local tax examinations by tax authorities for years before 2018. As of December 31, 2022 and 2021, we had no material unrecognized tax benefits. While we currently have no material unrecognized tax benefits, as a policy, we recognize penalties and interest accrued related to unrecognized tax benefits as income tax expense.
Segment Information	Segment Information Our primary business is the ownership, management, and redevelopment of retail and mixed-use properties. We review operating and financial information for each property on an individual basis and therefore, each property represents an individual operating segment. We evaluate financial performance using property operating income, which consists of rental income, and mortgage interest income, less rental expenses and real estate taxes. No individual commercial or residential property constitutes more than 10% of our revenues or property operating income and we have no operations outside of the United States of America. Therefore, we have aggregated our properties into one reportable segment as the properties share similar long-term economic characteristics and have other similarities including the fact that they are operated using consistent business strategies, are typically located in major metropolitan areas, and have similar tenant mixes.
Forward Equity Sales Policy	Forward Equity Sales Our at-the-market (“ATM”) equity program allows shares to be sold through forward sales contracts. Our forward sales contracts currently meet all the conditions for equity classification; and therefore, we record common stock on the settlement date at the purchase price contemplated by the contract. Furthermore, we consider the potential dilution resulting from forward sales contracts in our earnings per share calculations. We use the treasury method to determine the dilution, if any, from the forward sales contracts during the period of time prior to settlement. See Note 8 to the consolidated financial statements for details of our forward sales transactions.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Standard Description Effect on the financial statements or significant matters Adopted on January 1, 2022: ASU 2020-06, August 2020, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity This ASU simplifies the accounting for convertible instruments by removing the requirements to separately present certain conversion features in equity, simplifying the settlement assessment that entities are required to perform to determine whether a contract qualifies for equity classification, and generally requiring the use of the if-converted method for all convertible instruments in the diluted EPS calculation and include the effect of potential share settlement (if the effect is more dilutive). The guidance is effective for annual period beginning after December 15, 2021, and interim periods therein. The adoption of this standard did not have an impact to our consolidated financial statements. ASU 2021-05, July 2021, Lessors - Certain Leases with Variable Lease Payments (Topic 842) This ASU amends the lessor lease classification in ASC 842 for leases that include variable lease payments that are not based on an index or rate. Under the amended guidance, lessors will classify a lease with variable payments that do not depend on an index or rate as an operating lease if the lease would have been classified as a sales-type lease or a direct financing lease under the previous ASU 842 classification criteria, and sales-type or direct financing lease classification would result in a Day 1 loss. This guidance is effective for annual periods beginning after December 15, 2021, and interim periods therein. The adoption of this standard did not have an impact to our consolidated financial statements. Issued in 2022: ASU 2022-03, June 2022, Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions (Topic 820) This ASU clarifies that contractual sale restrictions are not considered in measuring the fair value of equity securities, and requires specific disclosures for all entities with equity securities subject to a contractual sale restriction including (1) the fair value of such equity securities reflected in the balance sheet, (2) the nature and remaining duration of the corresponding restrictions, and (3) any circumstances that could cause a lapse in the restrictions. In addition, the ASU prohibits an entity from recognizing a contractual sale as a separate unit of account. This guidance is effective in fiscal years beginning after December 15, 2023, and interim periods within those fiscal years, with early adoption permitted. We are assessing the impact of this ASU on OP units issued as consideration in future acquisitions. Issued in 2020: Reference Rate Reform (Topic 848) and related update: ASU 2020-04, March 2020, Reference Rate Reform (Topic 848) ASU 2022-06 , December 2022, Deferral of the Sunset Date This ASU provides companies with optional practical expedients to ease the accounting burden for contract modifications associated with transitioning away from LIBOR and other interbank offered rates that are expected to be discontinued as part of reference rate reform. For hedges, the guidance generally allows changes to the reference rate and other critical terms without having to de-designate the hedging relationship, as well as allows the shortcut method to continue to be applied. For contract modifications, changes in the reference rate or other critical terms will be treated as a continuation of the prior contract. ASU 2022-06 extended the period for which this guidance can be immediately applied through December 31, 2024. We expect to apply some of the practical expedients, as we are in the process of transitioning the $55.1 million mortgage loan on Hoboken and the $38.2 million mortgage loan related to the unconsolidated Assembly Row hotel (of which our share is $19.1 million) from LIBOR to alternative interest rates. We do not expect a significant impact to our financial results, financial position, or cash flows from this transition.
