Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Basis of Presentation and Summary of Significant Accounting Policies	1. Organization, Basis of Presentation and Summary of Significant Accounting Policies Organization The Company is a fully-integrated equity REIT focused on the ownership, acquisition, development, and management of retail properties located primarily in high-barrier-to-entry, supply-constrained, densely-populated metropolitan areas in the United States. All of the Company’s assets are held by, and all of its operations are conducted through, Acadia Realty Limited Partnership (the “Operating Partnership”) and entities in which the Operating Partnership owns an interest. As of June 30, 2022 and December 31, 2021, the Company controlled approximately 95 % of the Operating Partnership as the sole general partner and is entitled to share, in proportion to its percentage interest, in the cash distributions and profits and losses of the Operating Partnership. The limited partners primarily represent entities or individuals that contributed their interests in certain properties or entities to the Operating Partnership in exchange for common or preferred units of limited partnership interest (“Common OP Units” or “Preferred OP Units”) and employees who have been awarded restricted Common OP Units (“LTIP Units”) as long-term incentive compensation ( Note 13 ). Limited partners holding Common OP and LTIP Units are generally entitled to exchange their units on a one -for-one basis for common shares of beneficial interest, par value $ 0.001 per share, of the Company (“Common Shares”). This structure is referred to as an umbrella partnership REIT or “UPREIT.” As of June 30, 2022, the Company has ownership interests in 152 properties within its core portfolio, which consist of those properties either 100 % owned, or partially owned through joint venture interests, by the Operating Partnership, or subsidiaries thereof, not including those properties owned through its funds (“Core Portfolio”). The Company also has ownership interests in 51 properties within its opportunity funds, Acadia Strategic Opportunity Fund II, LLC (“Fund II”), Acadia Strategic Opportunity Fund III LLC (“Fund III”), Acadia Strategic Opportunity Fund IV LLC (“Fund IV”), and Acadia Strategic Opportunity Fund V LLC (“Fund V” and, collectively with Fund II, Fund III and Fund IV, the “Funds”). The 203 Core Portfolio and Fund properties primarily consist of street and urban retail and suburban shopping centers. In addition, the Company, together with the investors in the Funds, invested in operating companies through Acadia Mervyn Investors I, LLC (“Mervyns I,” which was liquidated in 2018) and Acadia Mervyn Investors II, LLC (“Mervyns II”), all on a non-recourse basis. The Company consolidates the Funds as it has (i) the power to direct the activities that most significantly impact the Funds’ economic performance, (ii) is obligated to absorb the Funds’ losses and (iii) has the right to receive benefits from the Funds that could potentially be significant. The Operating Partnership is the sole general partner or managing member of the Funds and Mervyns II and earns fees or priority distributions for asset management, property management, construction, development, leasing, and legal services. Cash flows from the Funds and Mervyns II are distributed pro-rata to their respective partners and members (including the Operating Partnership) until each receives a certain cumulative return (“Preferred Return”) and the return of all capital contributions. Thereafter, remaining cash flow is distributed 20 % to the Operating Partnership (“Promote”) and 80 % to the partners or members (including the Operating Partnership). All transactions between the Funds and the Operating Partnership have been eliminated in consolidation. The following table summarizes the general terms and Operating Partnership’s equity interests in the Funds and Mervyns II (dollars in millions): Entity Formation Operating Capital Called (b) Unfunded (b, c) Equity Interest (a) Preferred Total (b, c) Fund II and Mervyns II (c) 6/2004 40.00 % $ 385.3 $ — 40.00 % 8 % $ 172.1 Fund III 5/2007 24.54 % 448.1 1.9 24.54 % 6 % 601.5 Fund IV 5/2012 23.12 % 488.1 41.9 23.12 % 6 % 212.4 Fund V (d) 8/2016 20.10 % 347.9 172.1 20.10 % 6 % 71.7 (a) Amount represents the current economic ownership at June 30, 2022, which could differ from the stated legal ownership based upon the cumulative preferred returns of the respective Fund.

(c) During the second quarter of 2022, the Company increased its ownership in Fund II and Mervyns II by 11.67 % with the investment of $ 18.5 million. During August 2020, a recallable distribution of $ 15.7 million was made by Mervyn’s II to its investors, of which $ 4.5 million was the Company’s share. During 2021 and 2022, Mervyn’s II recalled $ 11.9 million and $ 3.8 million, respectively, of the $15.7 million, of which the Company's share is $ 3.4 million and $ 1.2 million, respectively. (d) As of April 8, 2021, Fund V's investment period was extended to August 25, 2022 . Basis of Presentation Restatement of Prior Year Amounts As discussed in the Company's 2021 consolidated financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2021 (the "Annual Report"), the Company restated each of the quarterly and year-to-date periods ended March 31, 2021, June 30, 2021 and September 30, 2021. Amounts as of or for the period ended June 30, 2021 depicted in these interim consolidated financial statements as "As Restated" are taken from the Company's restatement disclosures in the Annual Report on Form 10-K for the year ended December 31, 2021. See the 2021 consolidated financial statements included in the Annual Report for details of the restatement adjustments. Segments At June 30, 2022 , the Company had three reportable operating segments: Core Portfolio, Funds and Structured Financing. The Company’s chief operating decision maker may review operational and financial data on a property-level basis and does not differentiate properties on a geographical basis for purposes of allocating resources or capital. Principles of Consolidation The interim consolidated financial statements include the consolidated accounts of the Company and its investments in partnerships and limited liability companies in which the Company has control in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 810 “Consolidation” (“ASC Topic 810”). The ownership interests of other investors in these entities are recorded as noncontrolling interests. All significant intercompany balances and transactions have been eliminated in consolidation. Investments in entities for which the Company has the ability to exercise significant influence over, but does not have financial or operating control, are accounted for using the equity method of accounting. Accordingly, the Company’s share of the earnings (or losses) of these entities are included in consolidated net income or loss. The interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. Operating results for the interim periods presented are not necessarily indicative of the results that may be expected for the full fiscal year. The information furnished in the accompanying consolidated financial statements reflects all adjustments that, in the opinion of management, are necessary for a fair presentation of the aforementioned consolidated financial statements for the interim periods. Such adjustments consisted of normal recurring items. These interim consolidated financial statements should be read in conjunction with the Company’s 2021 consolidated financial statements included in the Annual Report. Use of Estimates GAAP requires the Company’s management to make estimates and assumptions that affect the amounts reported in the interim consolidated financial statements and accompanying notes. The most significant assumptions and estimates relate to the valuation of real estate, depreciable lives, revenue recognition and the collectability of notes receivable and rents receivable. Application of these estimates and assumptions requires the exercise of judgment as to future uncertainties and, as a result, actual results could differ from these estimates. Recently Adopted Accounting and Reporting Guidance In August 2020, the FASB issued ASU 2020-06— 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 certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. The ASU simplifies accounting for convertible instruments and simplifies the diluted earnings per share (EPS) calculation in certain areas. This ASU is effective for fiscal years beginning after December 15, 2021. Currently, the Company does not have any such debt instruments and, as a result, the implementation of this guidance did not have an effect on the Company’s consolidated financial statements. In May 2021, the FASB issued ASU 2021-04 Modification of Equity-Classified Written Call Options — Earnings Per Share (Topic 260), Debt—Modifications and Extinguishments (Subtopic 470-50), Compensation—Stock Compensation (Topic 718), and Derivatives and Hedging— Contracts in Entity’s Own Equity (Subtopic 815-40) : Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options — to codify how an issuer should account for modifications made to equity-classified written call options (a warrant to purchase the issuer’s common stock). The guidance in the ASU requires the issuer to treat a modification of an equity-classified warrant that does not cause the warrant to become liability-classified as an exchange whether structured as an amendment or reissuance and is effective for all periods beginning after December 15, 2021 with early application permitted. The Company does not currently have any outstanding equity awards with written call options. As a result, the implementation of this guidance did not have an effect on the Company’s consolidated financial statements. In July 2021, the FASB issued ASU 2021-05 Leases (Topic 842): Lessors—Certain Leases with Variable Lease Payments . This Update requires a lessor to classify a lease with entirely or partially variable payments that do not depend on an index or rate as an operating lease if another classification (i.e. sales-type or direct financing) would trigger a commencement date selling loss. The guidance in the ASU is effective for all periods beginning after December 15, 2021 with early application permitted and may be applied either retrospectively or prospectively. The Company does not currently have any sales-type or direct financing leases as lessor. As a result, the implementation of this guidance did not have an effect on the Company’s consolidated financial statements. In January 2021, the FASB issued ASU 2021-01 Reference Rate Reform (Topic 848) which modifies ASC 848, which was intended to provide relief related to “contracts and transactions that reference LIBOR or a reference rate that is expected to be discontinued as a result of reference rate reform.” ASU 2021-01 expands the scope of ASC 848 to include all affected derivatives and give reporting entities the ability to apply certain aspects of the contract modification and hedge accounting expedients to derivative contracts affected by the discounting transition. ASU 2021-01 also adds implementation guidance to clarify which optional expedients in ASC 848 may be applied to derivative instruments that do not reference LIBOR or a reference rate that is expected to be discontinued, but that are being modified as a result of the discounting transition. Currently, the Company does not anticipate the need to modify any existing debt agreements as a result of reference rate reform in the current year. If any modification is executed as a result of reference rate reform, the Company will elect the optional practical expedient under ASU 2020-04 and 2021-01, which allows entities to account for the modification as if the modification was not substantial. As a result, the implementation of this guidance is not expected to have an effect on the Company’s consolidated financial statements. Recently Issued Accounting Pronouncements In March 2022, the FASB issued ASU 2022-01 Derivatives and Hedging (Topic 815) Fair Value Hedging—Portfolio Layer Method . The amendments in this Update allow non-prepayable financial assets also to be included in a closed portfolio hedged using the portfolio layer method. That expanded scope permits an entity to apply the same portfolio hedging method to both prepayable and non-prepayable financial assets, thereby allowing consistent accounting for similar hedges. The guidance in the ASU is effective for all periods beginning after December 15, 2022 with early application permitted and may be applied prospectively. The Company does not currently utilize the portfolio layer method. As a result, the implementation of this guidance is not expected to have a material effect on the Company’s consolidated financial statements. In March 2022, the FASB issued ASU 2022-02 Financial Instruments—Credit Losses (Topic 326) Troubled Debt Restructurings and Vintage Disclosures . Rather than applying the recognition and measurement guidance for Troubled Debt Restructurings ("TDRs"), an entity must apply the loan refinancing and restructuring guidance in ASC 310-20-35-9 through 35-11 to determine whether a modification results in a new loan or a continuation of an existing loan. In addition, this Update requires that an entity disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20, Financial Instruments—Credit Losses—Measured at Amortized Cost . The guidance in the ASU is effective for all periods beginning after December 15, 2022 with early application permitted and may be applied prospectively. The Company does not currently have any financial instruments that meet the definition of a TDR. As a result, the implementation of this guidance is not expected to have a material effect on the Company’s consolidated financial statements. In June 2022, the FASB issued ASU 2022-03 Fair Value Measurement (Topic 820)—Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions . The guidance in this update clarifies how the fair value of equity securities subject to contractual sale restrictions is determined, and amends ASC 820 to clarify that a contractual sale restriction should not be considered in measuring fair value. It also requires entities with investments in equity securities subject to contractual sale restrictions to disclose certain qualitative and quantitative information about such securities. The guidance in the ASU is effective for all periods beginning after December 15, 2023 with early application permitted and may be applied prospectively. The Company's investment in Albertsons is subject to a contractual sale restriction, however, the Company does not consider this sale restriction in measuring its fair value ( Note 8 ). As a result, the implementation of this guidance is not expected to have an effect on the Company’s consolidated financial statements.

The Company invested $ 2.8 million in its 49.99 % equity interest and, through a separate lending subsidiary, provided a $ 64.1 million first mortgage loan and a $ 30.9 million mezzanine loan to subsidiaries of the venture (such equity and loans have been eliminated in consolidation). Pursuant to the entity’s operating agreement, the venture partner has a one-time right to put its 50.01 % interest in the entity (the "Williamsburg NCI", which is further described in Note 8 ) to the Company for fair value at a future date. Given the preferred rate of return of the Company embedded in its equity interests and the accruing debt senior to the equity, the Company did not attribute any initial redemption value to the Williamsburg NCI and recognized a bargain purchase gain of $ 1.2 million, which is included in Realized and unrealized holding (losses) gains on investments and other in the consolidated statements of operations. b) The Henderson Avenue Portfolio comprises 14 operating retail assets, one residential building and two development and redevelopment sites. c) The entity was previously accounted for as an equity method investment until an affiliate of Fund III acquired the venture partner's interest in a foreclosure action. Fund III now indirectly owns 100% of the entity and consolidates it ( Note 4 ). For the six months ended June 30, 2022 and the year ended December 31, 2021, the Company capitalized $ 1.2 million and $ 3.6 million of acquisition costs in connection with the 2022 Acquisitions and Foreclosure and the 2021 Acquisitions, respectively. In addition, during the six months ended June 30, 2022 , the Company expensed $ 2.0 million of acquisition costs (including a $ 1.5 million acquisition fee paid to an affiliate of a joint venture partner). Acquisition costs that were expensed are included in General and administrative expenses in the consolidated statements of operations. During the six months ended June 30, 2022, the Company assumed a $ 36.0 million mortgage with the consolidation of 640 Broadway and during the year ended December 31, 2021, the Company assumed a $ 31.8 million mortgage with the acquisition of Canton Marketplace ( Note 7 ). Purchase Price Allocations The purchase prices for the 2022 Acquisitions and Foreclosure and 2021 Acquisitions were allocated to the acquired assets and assumed liabilities based on their estimated fair values at the dates of acquisition.

Notes Re ceivable, Net The Company’s notes receivable, net are generally collateralized either by the underlying properties or the borrowers’ ownership interests in the entities that own the properties, and were as follows (dollars in thousands): June 30, December 31, June 30, 2022 Description 2022 2021 Number Maturity Date Interest Rate Core Portfolio (a) $ 138,331 $ 154,332 7 Apr 2020 - Dec 2027 4.65 % - 12.00 % Fund III — 5,306 — — — Total notes receivable 138,331 159,638 Allowance for credit loss ( 1,025 ) ( 5,752 ) Notes receivable, net $ 137,306 $ 153,886 7 a) Includes one note receivable from an OP Unit holder, with a balance of $ 6.0 million at June 30, 2022 and December 31, 2021 . During the six months ended June 30, 2022, the Company: • through Fund III obtained the remaining venture partner's interest in an entity that held a property, which was collateral for a note with a balance of $ 5.3 million, accrued interest of $ 4.7 million less credit loss reserve of $ 4.6 million, via a foreclosure auction in January 2022. The entity was previously accounted for as an equity method investment until Fund III acquired the venture partner's interest in a foreclosure auction. Fund III now owns 100 % of the entity and consolidates it ( Note 4 ); • received full payment on a $ 16.0 million Core Portfolio loan during the second quarter. See Note 15 for repayments subsequent to June 30, 2022; and • decreased the credit loss reserve by $ 0.1 million as a result of the aforementioned repayment. During the year ended December 31, 2021, the Company: • originated a new Core Portfolio note for $ 16.0 million with a stated interest rate of 9 % and a maturity date of October 20, 2022 collateralized by a single tenant property in Silver Spring, Maryland on April 20, 2021; • exchanged 21,109 OP Units in settlement of a note receivable in the amount of $ 0.5 million on July 12, 2021 ( Note 10 ); • originated a new Core Portfolio note for $ 43.0 million, of which $ 42.0 million was funded, with three tranches with stated interest rates ranging from 5 % to 12 % and a maturity date of September 17, 2024 collateralized by a retail condominium in Soho, New York on September 17, 2021; • extended the maturity date of one Core note receivable of $ 13.5 million from October 28, 2021 to June 1, 2022 ; and • recorded an increase in its allowance for credit loss of approximately $ 4.5 million primarily attributable to the Fund III note that matured in July 2020 . Default One Core Portfolio note aggregating $ 21.6 million including accrued interest (exclusive of default interest and other amounts due on the loan that have not been recognized) was in default at June 30, 2022 and December 31, 2021 . On April 1, 2020, the loan matured and was not repaid. The Company expects to take appropriate actions to recover the amounts due under the loan and has issued a reservation of rights letter to the borrowers and guarantor, reserving all of its rights and remedies under the applicable loan documents and otherwise. The Company has determined that the collateral for this loan is sufficient to cover the loan’s carrying value at June 30, 2022 and December 31, 2021. Allowance for Credit Losses The Company monitors the credit quality of its notes receivable on an ongoing basis and considers indicators of credit quality such as loan payment activity, the estimated fair value of the underlying collateral, the seniority of the Company’s loan in relation to other debt secured by the collateral and the prospects of the borrower. Earnings from these notes and mortgages receivable are reported within the Company’s Structured Financing segment ( Note 12 ). Interest receivable is included in Other assets ( Note 5 ). The Company’s estimated allowance for credit losses related to its Structured Financing segment has been computed for its amortized cost basis in the portfolio, including accrued interest ( Note 5 ), factoring historical loss experience in the United States for similar loans, as adjusted for current conditions, as well as the Company’s expectations related to future economic conditions. Due to the lack of comparability across the Structured Financing portfolio, each loan was evaluated separately. As a result, there were four non-collateral-dependent loans with a total amortized cost of $ 129.2 million, inclusive of accrued interest of $ 14.7 million, for which an allowance for credit losses has been recorded aggregating $ 1 million at June 30, 2022. For two loans in this portfolio, aggregating $ 27.9 million, inclusive of accrued interest of $ 4.1 million at June 30, 2022 , the Company has elected to apply a practical expedient in accordance with ASC 326 and did no t establish an allowance for credit losses because (i) these loans are collateral-dependent loans, which due to their settlement terms are not expected to be settled in cash but rather by the Company’s possession of the real estate collateral; and (ii) at June 30, 2022 , the Company determined that the estimated fair value of the collateral at the expected realization date for these loans was sufficient to cover the carrying value of its investments in these notes receivable. Impairment charges may be required if and when such amounts are estimated to be nonrecoverable upon a realization event, which is generally at the time a loan is repaid, or in the case of foreclosure, when the underlying asset is sold; however, non-recoverability may also be concluded if it is reasonably certain that all amounts due will not be collected.

Unsecured Revolving Line of Credit At June 30, 2022 and December 31, 2021, the Company had a total of $ 199.5 million and $ 183.1 million available under its Revolver, reflecting borrowings of $ 96.5 million and $ 112.9 million and letters of credit of $ 4.0 million and $ 4.0 million, respectively. At each of June 30, 2022 and December 31, 2021, all of the Revolver was swapped to a fixed rate. Scheduled Debt Principal Payments The scheduled principal repayments, without regard to available extension options (described further below), of the Company’s consolidated indebtedness, as of June 30, 2022 are as follows (in thousands): Year Ending December 31, 2022 (Remainder) $ 430,916 2023 238,792 2024 212,128 2025 204,220 2026 445,975 Thereafter 290,770 1,822,801 Unamortized premium 394 Net unamortized debt issuance costs ( 8,969 ) Total indebtedness $ 1,814,226 The table above does not reflect available extension options (subject to customary conditions) on consolidated debt with balances as of June 30, 2022 of $ 93.8 million contractually due in the remainder of 2022 and $ 84.4 million contractually due in 2023; most for which the Company has available options to extend by up to 12 months and for some an additional 12 months thereafter. However, there can be no assurance that the Company will be able to successfully execute any or all of its available extension options. Of the debt maturing in 2022 and 2023, $ 256.7 million and $ 39.5 million, respectively, relates to Fund II's City Point property, which were refinanced in August 2022 ( Note 15 ).

Fair Value Disclosures [Abstract]
Financial Instruments and Fair Value Measurements	8. Financial Instruments and Fair Value Measurements The fair value of an asset is defined as the exit price, which is the amount that would either be received when an asset is sold or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The guidance establishes a three-tier fair value hierarchy based on the inputs used in measuring fair value. These tiers are: Level 1, for which quoted market prices for identical instruments are available in active markets, such as money market funds, equity securities, and U.S. Treasury securities; Level 2, for which there are inputs other than quoted prices included within Level 1 that are observable for the instrument, such as certain derivative instruments including interest rate caps and interest rate swaps; and Level 3, for financial instruments or other assets/liabilities that do not fall into Level 1 or Level 2 and for which little or no market data exists, therefore requiring the Company to develop its own assumptions. Items Measured at Fair Value on a Recurring Basis The methods and assumptions described below were used to estimate the fair value of each class of financial instrument. Money Market Funds — The Company has money market funds, which at times have zero balances and are included in Cash and cash equivalents in the consolidated balance sheets, and are comprised of government securities and/or U.S. Treasury bills. These funds were classified as Level 1 which include quoted prices from active markets to determine their fair values. Equity Investments –Albertsons became publicly traded during 2020 ( Note 4 ). Upon Albertsons’ IPO, the Company’s Investment in Albertsons has a readily determinable market value (traded on an exchange) and is being accounted for as a Level 1 investment. Derivative Assets — The Company has derivative assets, which are included in Other assets, net on the consolidated balance sheets, and are comprised of interest rate swaps and caps. The derivative instruments were measured at fair value using readily observable market inputs, such as quotations on interest rates, and were classified as Level 2 as these instruments are custom, over-the-counter contracts with various bank counterparties that are not traded in an active market. See “Derivative Financial Instruments,” below. Derivative Liabilities — The Company has derivative liabilities, which are included in Accounts payable and other liabilities on the consolidated balance sheets, and are comprised of interest rate swaps. These derivative instruments were measured at fair value using readily observable market inputs, such as quotations on interest rates, and were classified as Level 2 because they are custom, over-the-counter contracts with various bank counterparties that are not traded in an active market. See “Derivative Financial Instruments,” below. The Company did not have any transfers into or out of Level 1, Level 2, and Level 3 measurements during the six months ended June 30, 2022 or 2021. The following table presents the Company’s fair value hierarchy for those assets and liabilities measured at fair value on a recurring basis (in thousands): June 30, 2022 December 31, 2021 Level 1 Level 2 Level 3 Level 1 Level 2 Level 3 Assets Money market funds $ — $ — $ — $ — $ — $ — Derivative financial instruments — 14,098 — — 7 — Investment in Albertsons (Note 4) 110,039 — — 124,316 — — Liabilities Derivative financial instruments — 1,582 — — 45,027 — In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability. Items Measured at Fair Value on a Nonrecurring Basis Impairment Charges During 2021, the Company was impacted by the COVID-19 Pandemic, which caused the Company to reduce its forecasted operating income at certain properties. As a result, several impairments were recorded. Impairment charges for the periods presented are as follows (in thousands): Impairment Charge Property and Location Owner Triggering Event Level 3 Inputs Effective Date Total Acadia's Share 2022 Impairment Charges None 2021 Impairment Charges 210 Bowery commercial unit, Fund IV Reduced projected operating income Projections of: holding period, net operating income, cap rate, incremental costs Sept 30, 2021 $ 3,016 $ 697 27 E. 61st Street Fund IV Reduced projected operating income Projections of: holding period, net operating income, cap rate, incremental costs Sept 30, 2021 6,909 1,597 Total 2021 Impairment Charges $ 9,925 $ 2,294 Redeemable Noncontrolling Interest In connection with the Williamsburg Portfolio acquisition in February 2022 ( Note 2 ), the Company evaluated the Williamsburg Noncontrolling Interest ("NCI"), which represents the venture partner's one-time right to put its 50.01% interest in the property to the Company for fair value at a future date. As it was unlikely as of the acquisition date that the venture partner would receive any consideration on redemption due to the Company’s preferential returns, the amount of the senior debt that would accrue and the estimated fair value of the property, the initial fair value of the Williamsburg NCI was determined to be zero. The Company is required to periodically evaluate the noncontrolling interest and adjust it to fair value, should it become likely that the venture partner would receive consideration for exercising its put right. At June 30, 2022 , the Company determined that the fair value of the Williamsburg NCI was zero . Derivative Financial Instruments The Company had the following interest rate swaps and caps for the periods presented (dollars in thousands): Strike Rate Fair Value Derivative Aggregate Notional Amount Effective Date Maturity Date Low High Balance Sheet June 30, December 31, Core Interest Rate Swaps $ 185,295 Dec 2012 - Aug 2022 Dec 2022 - Jul 2030 2.92 % — 3.77 % Other Liabilities $ ( 1,582 ) $ ( 40,650 ) Interest Rate Swap 416,460 Mar 2015 - Jun 2019 Mar 2025 - Jun 2029 1.71 % — 2.60 % Other Assets 7,431 — $ 601,755 $ 5,849 $ ( 40,650 ) Fund III Interest Rate Caps $ 35,970 Jan 2021 Jul 2022 3.00 % — 3.00 % Other Assets $ — $ — Fund IV Interest Rate Swaps $ — Mar 2017 - Jan 2019 Apr 2022 1.97 % — 2.61 % Other Assets $ — $ — Interest Rate Swaps — Other Liabilities — ( 167 ) Interest Rate Caps 71,338 Dec 2020 - Jul 2021 Dec 2022 - Jul 2023 3.00 % — 3.50 % Other Assets 97 7 $ 71,338 $ 97 $ ( 160 ) Fund V Interest Rate Swaps $ 338,109 Jun 2018 - Apr 2022 Oct 2022 - Apr 2025 0.91 % — 2.88 % Other Assets $ 6,570 $ — Interest Rate Swaps — Other Liabilities — ( 4,210 ) $ 338,109 $ 6,570 $ ( 4,210 ) Total asset derivatives $ 14,098 $ 7 Total liability derivatives $ ( 1,582 ) $ ( 45,027 ) All of the Company’s derivative instruments have been designated as cash flow hedges and hedge the future cash outflows on variable-rate debt ( Note 7 ). It is estimated that approximately $ 6.1 million included in Accumulated other comprehensive income related to derivatives will be reclassified to interest expense within the next twelve months. As of June 30, 2022 and December 31, 2021 , no derivatives were designated as fair value hedges or hedges of net investments in foreign operations. Additionally, the Company does not use derivatives for trading or speculative purposes and currently does not have any derivatives that are not designated hedges. During the first quarter of 2021, the Company terminated two interest rate swaps with forward effective dates with an aggregate notional value of $ 100.0 million for cash pr oceeds of $ 3.4 million. As the hedged forecasted transaction is still expected, amounts deferred in Accumulated other comprehensive loss will be amortized into earnings as a reduction of interest expense over the original term of the swaps beginning in 2022. Risk Management Objective of Using Derivatives The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company manages economic risks, including interest rate, liquidity and credit risk, primarily by managing the amount, sources and duration of its debt funding and, from time to time, through the use of derivative financial instruments. The Company enters into derivative financial instruments to manage exposures that result in the receipt or payment of future known and uncertain cash amounts, the values of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to the Company’s investments and borrowings. The Company is exposed to credit risk in the event of non-performance by the counterparties to the swaps if the derivative position has a positive balance. The Company believes it mitigates its credit risk by entering into swaps with major financial institutions. The Company continually monitors and actively manages interest costs on its variable-rate debt portfolio and may enter into additional interest rate swap positions or other derivative interest rate instruments based on market conditions. Credit Risk-Related Contingent Features The Company has agreements with each of its swap counterparties that contain a provision whereby if the Company defaults on certain of its unsecured indebtedness, the Company could also be declared in default on its swaps, resulting in an acceleration of payment under the swaps. Other Financial Instruments The Company’s other financial instruments had the following carrying values and fair values as of the dates shown (dollars in thousands, inclusive of amounts attributable to noncontrolling interests where applicable): June 30, 2022 December 31, 2021 Level Carrying Estimated Carrying Estimated Notes Receivable (a) 3 $ 137,306 $ 133,989 $ 153,886 $ 154,093 Mortgage and Other Notes Payable (a) 3 1,108,011 1,075,664 1,143,805 1,125,571 Investment in non-traded equity securities (b) 3 3,828 6,009 3,656 4,062 Unsecured notes payable and Unsecured line of credit (c) 2 714,790 713,041 675,933 680,171 (a) The Company determined the estimated fair value of these financial instruments using a discounted cash flow model with rates that take into account the credit of the borrower or tenant, where applicable, and interest rate risk. The Company also considered the value of the underlying collateral, taking into account the quality of the collateral, the credit quality of the borrower, the time until maturity and the current market interest rate environment. Amounts exclude discounts and loan costs. (b) Represents the Operating Partnership’s cost-method investment in Fifth Wall ( Note 4 ) . (c) The Company determined the estimated fair value of the unsecured notes payable and unsecured line of credit using quoted market prices in an open market with limited trading volume where available. In cases where there was no trading volume, the Company determined the estimated fair value using a discounted cash flow model using a rate that reflects the average yield of similar market participants. The Company’s cash and cash equivalents, restricted cash, rents receivable, accounts payable and certain financial instruments included in other assets and other liabilities had fair values that approximated their carrying values due to their short maturity profiles at June 30, 2022 .

Distributions declared for Preferred OP Units are reflected in net income (loss) in the table above. (b) Noncontrolling interests in partially-owned affiliates comprise third-party interests in Funds II, III, IV and V, and Mervyns II, and six other subsidiaries. (c) Represents the acquisition of the 11.67 % noncontrolling interest in Fund II and Mervyns II acquired on June 27, 2022 ( Note 1 ) for $ 18.5 million. (d) Adjustment reflects the difference between the fair value of the consideration received or paid and the book value of the Common Shares, Common OP Units, Preferred OP Units, and LTIP Units involving changes in ownership. Preferred OP Units There were no issuances of Preferred OP Units during the six months ended June 30, 2022 or the year ended December 31, 2021. In 1999, the Operating Partnership issued 1,580 Series A Preferred OP Units in connection with the acquisition of a property, which have a stated value of $ 1,000 per unit, and are entitled to a preferred quarterly distribution of the greater of (i) $ 22.50 ( 9 % annually) per Series A Preferred OP Unit or (ii) the quarterly distribution attributable to a Series A Preferred OP Unit if such unit was converted into a Common OP Unit. Through June 30, 2022 , 1,392 Series A Preferred OP Units were converted into 185,600 Common OP Units and then into Common Shares. The 188 remaining Series A Preferred OP Units are currently convertible into Common OP Units based on the stated value divided by $ 7.50 . Either the Company or the holders can currently call for the conversion of the Series A Preferred OP Units at the lesser of $7.50 or the market price of the Common Shares as of the conversion date. During 2016, the Operating Partnership issued 442,478 Common OP Units and 141,593 Series C Preferred OP Units to a third party to acquire Gotham Plaza ( Note 4 ). The Series C Preferred OP Units have a value of $ 100.00 per unit and are entitled to a preferred quarterly distribution of $ 0.9375 per unit and are convertible into Common OP Units at a rate based on the share price at the time of conversion. If the share price is below $28.80 on the conversion date, each Series C Preferred OP Unit will be convertible into 3.4722 Common OP Units. If the share price is between $ 28.80 and $ 35.20 on the conversion date, each Series C Preferred OP Unit will be convertible into a number of Common OP Units equal to $100.00 divided by the closing share price. If the share price is above $35.20 on the conversion date, each Series C Preferred OP Unit will be convertible into 2.8409 Common OP Units. The Series C Preferred OP Units have a mandatory conversion date of December 31, 2025, at which time all units that have not been converted will automatically be converted into Common OP Units based on the same calculations. Through June 30, 2022 , 15,000 Series C Preferred OP Units were converted into 51,887 Common OP Units and then into Common Shares.

Leases [Abstract]
Leases	11. Leases As Lessor The Company is engaged in the operation of shopping centers and other retail properties that are either owned or, with respect to certain shopping centers, operated under long-term ground leases that expire at various dates through June 20, 2066, with renewal options (as discussed further below). Space in the shopping centers is leased to tenants pursuant to agreements that provide for terms ranging generally from one month to sixty years and generally provide for additional rents based on certain operating expenses as well as tenants’ sales volumes. During the six months ended June 30, 2022 and 2021, the Company earned $ 30.2 million and $ 29.3 million, respectively in variable lease revenues, primarily for real estate taxes and common area maintenance charges, which are included in rental income in the consolidated statements of operations. Reserve Analysis The activity for the reserves related to billed rents and straight-line rents (including those under specific operating leases where the collection of rents is assessed to be not probable) is as follows: Six Months Ended June 30, 2022 Balance at Provision (Recovery), Net Adjustments Write-Offs Balance at Allowance for credit loss - billed rents $ 23,586 $ ( 1,387 ) $ — $ ( 4,031 ) $ 18,168 Straight-line rent reserves 14,885 ( 462 ) — ( 1,276 ) 13,147 Total - rents receivable $ 38,471 $ ( 1,849 ) $ — $ ( 5,307 ) $ 31,315 Tenant Settlement On September 24, 2021, the Company entered into a conditional settlement agreement with its former tenant ("Former Tenant") and lease guarantor at one of its Core properties for the payment by Former Tenant and guarantor of a minimum of $ 5.4 million in accordance with a payment schedule set forth and subject to the terms in the conditional settlement agreement. The payments relate to the Former Tenant’s default under the lease and its subsequent termination by the Company. Given the inherent uncertainties involving collectability, the Company has deferred any amounts not received in its consolidated financial statements and such amounts will be recognized when realized. Through June 30, 2022 the Company had received a total of $ 2.4 million, of which $ 1.5 million and $ 2.4 million was recognized as credit loss recoveries and included in Rental income on the statement of operations during the three and six months ended June 30, 2022, respectively. As Lessee During the six months ended June 30, 2022 , there were no leasing transactions where the Company acted as lessee. During the year ended December 31, 2021, the Company: • modified its Rye, New York corporate office lease during the first quarter of 2021. As a result of the modification, the lease was remeasured, and the lease liability and right-of-use asset were each reduced by $ 0.4 million; and • terminated its Fund IV lease at 110 University Place in New York City during the second quarter of 2021 (which was previously impaired in 2020) for $ 3.6 million, and de-recognized the related right-of-use asset of $ 31.4 million, lease liability of $ 46.0 million and building improvements and other assets totaling $ 10.3 million, resulting in a gain on lease termination of $ 0.7 million, or $ 0.2 million at the Company's share, which is reflected within Gain on disposition of properties in the consolidated statements of operations.

Segment Reporting [Abstract]
Segment Reporting	12. Segmen t Reporting The Company has three reportable segments: Core Portfolio, Funds and Structured Financing. The Company’s Core Portfolio consists primarily of high-quality retail properties located primarily in high-barrier-to-entry, densely-populated metropolitan areas with a long-term investment horizon. The Company’s Funds hold primarily retail real estate in which the Company co-invests with high-quality institutional investors. The Company’s Structured Financing segment consists of earnings and expenses related to notes and mortgages receivable which are held within the Core Portfolio or the Funds ( Note 3 ). Fees earned by the Company as the general partner or managing member of the Funds are eliminated in the Company’s consolidated financial statements and are not presented in the Company’s segments.

Share-based Payment Arrangement [Abstract]
Share Incentive and Other Compensation	13. Share Incentive a nd Other Compensation Share Incentive Plan The 2020 Share Incentive Plan (the “Share Incentive Plan”) authorizes the Company to issue options, Restricted Shares, LTIP Units and other securities (collectively “Awards”) to, among others, the Company’s officers, trustees and employees. At June 30, 2022 a total of 1,490,135 shares remained available to be issued under the Share Incentive Plan. Restricted Shares and LTIP Units - Employees During the six months ended June 30, 2022, and the year ended December 31, 2021 , the Company issued 600,672 and 636,646 LTIP Units and 13,178 and 11,244 restricted share units (“Restricted Share Units”), respectively, to employees of the Company pursuant to the Share Incentive Plan. These awards were measured at their fair value on the grant date, incorporating the following factors: • A portion of these annual equity awards is granted in performance-based Restricted Share Units or LTIP Units that may be earned based on the Company’s attainment of specified relative total shareholder returns (“Relative TSR”) hurdles. • In the event the Relative TSR percentile falls between the 25th percentile and the 50th percentile, the Relative TSR vesting percentage is determined using a straight-line linear interpolation between 50 % and 100 % and in the event that the Relative TSR percentile falls between the 50th percentile and 75th percentile, the Relative TSR vesting percentage is determined using a straight-line linear interpolation between 100 % and 200 %. • Two-thirds (2/3) of the performance-based LTIP Units will vest based on the Company’s total shareholder return (“TSR”) for the three-year forward-lo oking performance period relative to the constituents of the National Association of Real Estate Investment Trusts (“NAREIT”) Shopping Center Property Subsector and one-third (1/3) on the Company’s TSR for the three-year forward-looking performance period as compared to the constituents of the NAREIT Retail Property Sector (both on a non-weighted basis). • If the Company’s performance fails to achieve the aforementioned hurdles at the culmination of the three-year performance period, all performance-based shares will be forfeited. Any earned performance-based shares vest 60 % at the end of the performance period, with the remaining 40 % of shares vesting ratably over the next two years . For valuation of the 2022 and 2021 Performance Shares, a Monte Carlo simulation was used to estimate the fair values based on probability of satisfying the market conditions and the projected share prices at the time of payments, discounted to the valuation dates over the three-year performance periods. The assumptions include volatility ( 49.0 % and 48.0 %) and risk-free interest rates of ( 1.7 % and 0.2 %) for 2022 and 2021, respectively. The total value of the 2022 and 2021 Performance Shares will be expensed over the vesting period regardless of the Company’s performance. The total value of the above Restricted Share Units and LTIP Units as of the grant date was $ 13.0 million during the six months ended June 30, 2022 and $ 12.6 million during the year ended December 31, 2021 . Total long-term incentive compensation expense, including the expense related to the Share Incentive Plan, was $ 2.2 million and $ 2.3 million for the three months end ed June 30, 2022 and 2021, and $3.2 million and $ 4.7 million for the six months ended June 30, 2022 and 2021, respectively and is recorded in General and administrative expense in the consolidated statements of operations. Restricted Shares and LTIP Units - Board of Trustees In addition, members of the Board have been issued shares and units under the Share Incentive Plan. During the six months ended June 30, 2022 , the Company issued 28,555 LTIP Units and 29,935 Restricted Share Units as compensation to the Trustees of the Company. A portion of the LTIP Units and Restricted Share Units vest over three years with 33 % vesting May 9, 2023 and the remaining amount vesting ratably on May 9, 2024 and May 9, 2025. The remaining awards vest on May 9, 2023. The Restricted Shares do not carry voting rights or other rights of Common Shares until vesting and may not be transferred, assigned or pledged until the recipients have a vested non-forfeitable right to such shares. Dividends are not paid currently on unvested Restricted Shares, but are paid cumulatively from the issuance date through the applicable vesting date of such Restricted Shares. Total trustee fee expense, including the expense related to the Share Incentive Plan, was $ 0.8 million for each of the six months ended June 30, 2022 and 2021, respectively, and is recorded in General and Administrative expense in the consolidated statements of operations. Long-Term Incentive Alignment Program In 2009, the Company adopted the Long-Term Incentive Alignment Program (the “Program”) pursuant to which the Company may grant awards to employees, entitling them to receive up to 25 % of any potential future payments of Promote to the Operating Partnership from Funds III, IV and V. The Company has granted such awards to employees representing 25 % of the potential Promote payments from Fund III to the Operating Partnership, 23.1 % of the potential Promote payments from Fund IV to the Operating Partnership and 10.9 % of the potential Promote payments from Fund V to the Operating Partnership. Payments to senior executives under the Program require further Board approval at the time any potential payments are due pursuant to these grants. Compensation relating to these awards will be recognized in each reporting period in which Board approval is granted. As payments to other employees are not subject to further Board approval, compensation relating to these awards will be recorded based on the estimated fair value at each reporting period in accordance with ASC Topic 718, Compensation– Stock Compensation. The awards in connection with Fund IV were determined to have no intrinsic value as of June 30, 2022 or December 31, 2021. The Company recognized $ 0.4 million and $ 0.1 million of compensation expense for Funds III and V, respectively for the six months ended June 30, 2022 related to the Program in connection with the resignation of an employee. No compensation expense was recognized for the year ended December 31, 2021 related to the Program. A summary of the status of the Company’s unvested Restricted Shares and LTIP Units is presented below: Unvested Restricted Shares and LTIP Units Common Weighted LTIP Units Weighted Unvested at December 31, 2020 89,911 $ 15.42 1,122,889 $ 24.38 Granted 43,078 19.94 666,967 19.48 Vested ( 43,084 ) 16.85 ( 283,024 ) 26.66 Forfeited ( 159 ) 36.22 ( 91,637 ) 36.22 Unvested at December 31, 2021 89,746 16.87 1,415,195 20.85 Granted 43,113 21.36 629,227 21.16 Vested ( 38,088 ) 20.10 ( 308,608 ) 22.88 Forfeited ( 920 ) 43.76 ( 233,754 ) 32.72 Unvested at June 30, 2022 93,851 $ 17.35 1,502,060 $ 18.72 The weighted-average grant date fair value for Restricted Shares and LTIP Units granted for the six months ended June 30, 2022 and the year ended December 31, 2021 were $ 21.17 and $ 19.51 , respectively. As of June 30, 2022 , there was $ 21.4 million of total unrecognized compensation cost related to unvested share-based compensation arrangements granted under the Share Incentive Plan. That cost is expected to be recognized over a weighted-average period of 1.6 years. The total fair value of Restricted Shares that vested during the six months ended June 30, 2022 and the year ended December 31, 2021 , was $ 0.8 million and $ 0.8 million, respectively. The total fair value of LTIP Units that vested (LTIP units vest primarily during the first quarter) during the six months ended June 30, 2022 and the year ended December 31, 2021 , was $ 7.1 million and $ 7.5 million, respectively. Other Plans On a combined basis, the Company incurred a total of $ 0.3 million of compensation expense related to the following employee benefit plans for each of the six months ended June 30, 2022 and 2021. Employee Share Purchase Plan The Acadia Realty Trust Employee Share Purchase Plan (the “Purchase Plan”), allows eligible employees of the Company to purchase Common Shares through payroll deductions. The Purchase Plan provides for employees to purchase Common Shares on a quarterly basis at a 15 % discount to the closing price of the Company’s Common Shares on either the first day or the last day of the quarter, whichever is lower. A participant may not purchase more than $ 25,000 in Common Shares per year. Compensation expense will be recognized by the Company to the extent of the above discount to the closing price of the Common Shares with respect to the applicable quarter. A total of 3,674 and 4,651 Common Shares were purchased by employees under the Purchase Plan for the six months ended June 30, 2022 and 2021, respectively. Deferred Share Plan The Company maintains a Trustee Deferral and Distribution Election program, under which the participating Trustees earn deferred compensation. Employee 401(k) Plan The Company maintains a 401(k) plan for employees under which the Company currently matches 50 % of a plan participant’s contribution up to 6 % of the employee’s annual salary. A plan participant may contribute up to a maximum of 15 % of their compensation, up to $ 20,500 , for the year ending December 31, 2022.

Earnings Per Common Share

Earnings Per Common Share	6 Months Ended

Earnings Per Share [Abstract]
Earnings Per Common Share	14. Earnings P er Common Share Basic earnings per Common Share is computed by dividing net income attributable to Common Shareholders by the weighted-average Common Shares outstanding ( Note 10 ). During the periods presented, the Company had unvested LTIP Units which provide for non-forfeitable rights to dividend equivalent payments. Accordingly, these unvested LTIP Units are considered participating securities and are included in the computation of basic earnings per Common Share pursuant to the two-class method. Diluted earnings per Common Share reflects the potential dilution of the conversion of obligations and the assumed exercises of securities including the effects of Restricted Share Units issued under the Company’s Share Incentive Plans ( Note 13 ). The effect of such shares is excluded from the calculation of earnings per share when anti-dilutive as indicated in the table below. The effect of the conversion of Common OP Units is not reflected in the computation of basic and diluted earnings per share, as they are exchangeable for Common Shares on a one -for-one basis . The income allocable to such units is allocated on this same basis and reflected as noncontrolling interests in the accompanying consolidated financial statements. As such, the assumed conversion of these units would have no net impact on the determination of diluted earnings per share.

Basis of Presentation	Basis of Presentation Restatement of Prior Year Amounts As discussed in the Company's 2021 consolidated financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2021 (the "Annual Report"), the Company restated each of the quarterly and year-to-date periods ended March 31, 2021, June 30, 2021 and September 30, 2021. Amounts as of or for the period ended June 30, 2021 depicted in these interim consolidated financial statements as "As Restated" are taken from the Company's restatement disclosures in the Annual Report on Form 10-K for the year ended December 31, 2021. See the 2021 consolidated financial statements included in the Annual Report for details of the restatement adjustments.
Segments	Segments At June 30, 2022 , the Company had three reportable operating segments: Core Portfolio, Funds and Structured Financing. The Company’s chief operating decision maker may review operational and financial data on a property-level basis and does not differentiate properties on a geographical basis for purposes of allocating resources or capital.
Principles of Consolidation	Principles of Consolidation The interim consolidated financial statements include the consolidated accounts of the Company and its investments in partnerships and limited liability companies in which the Company has control in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 810 “Consolidation” (“ASC Topic 810”). The ownership interests of other investors in these entities are recorded as noncontrolling interests. All significant intercompany balances and transactions have been eliminated in consolidation. Investments in entities for which the Company has the ability to exercise significant influence over, but does not have financial or operating control, are accounted for using the equity method of accounting. Accordingly, the Company’s share of the earnings (or losses) of these entities are included in consolidated net income or loss. The interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. Operating results for the interim periods presented are not necessarily indicative of the results that may be expected for the full fiscal year. The information furnished in the accompanying consolidated financial statements reflects all adjustments that, in the opinion of management, are necessary for a fair presentation of the aforementioned consolidated financial statements for the interim periods. Such adjustments consisted of normal recurring items. These interim consolidated financial statements should be read in conjunction with the Company’s 2021 consolidated financial statements included in the Annual Report.
Use of Estimates	Use of Estimates GAAP requires the Company’s management to make estimates and assumptions that affect the amounts reported in the interim consolidated financial statements and accompanying notes. The most significant assumptions and estimates relate to the valuation of real estate, depreciable lives, revenue recognition and the collectability of notes receivable and rents receivable. Application of these estimates and assumptions requires the exercise of judgment as to future uncertainties and, as a result, actual results could differ from these estimates.
Recently Adopted Accounting and Reporting Guidance	Recently Adopted Accounting and Reporting Guidance In August 2020, the FASB issued ASU 2020-06— 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 certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. The ASU simplifies accounting for convertible instruments and simplifies the diluted earnings per share (EPS) calculation in certain areas. This ASU is effective for fiscal years beginning after December 15, 2021. Currently, the Company does not have any such debt instruments and, as a result, the implementation of this guidance did not have an effect on the Company’s consolidated financial statements. In May 2021, the FASB issued ASU 2021-04 Modification of Equity-Classified Written Call Options — Earnings Per Share (Topic 260), Debt—Modifications and Extinguishments (Subtopic 470-50), Compensation—Stock Compensation (Topic 718), and Derivatives and Hedging— Contracts in Entity’s Own Equity (Subtopic 815-40) : Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options — to codify how an issuer should account for modifications made to equity-classified written call options (a warrant to purchase the issuer’s common stock). The guidance in the ASU requires the issuer to treat a modification of an equity-classified warrant that does not cause the warrant to become liability-classified as an exchange whether structured as an amendment or reissuance and is effective for all periods beginning after December 15, 2021 with early application permitted. The Company does not currently have any outstanding equity awards with written call options. As a result, the implementation of this guidance did not have an effect on the Company’s consolidated financial statements. In July 2021, the FASB issued ASU 2021-05 Leases (Topic 842): Lessors—Certain Leases with Variable Lease Payments . This Update requires a lessor to classify a lease with entirely or partially variable payments that do not depend on an index or rate as an operating lease if another classification (i.e. sales-type or direct financing) would trigger a commencement date selling loss. The guidance in the ASU is effective for all periods beginning after December 15, 2021 with early application permitted and may be applied either retrospectively or prospectively. The Company does not currently have any sales-type or direct financing leases as lessor. As a result, the implementation of this guidance did not have an effect on the Company’s consolidated financial statements. In January 2021, the FASB issued ASU 2021-01 Reference Rate Reform (Topic 848) which modifies ASC 848, which was intended to provide relief related to “contracts and transactions that reference LIBOR or a reference rate that is expected to be discontinued as a result of reference rate reform.” ASU 2021-01 expands the scope of ASC 848 to include all affected derivatives and give reporting entities the ability to apply certain aspects of the contract modification and hedge accounting expedients to derivative contracts affected by the discounting transition. ASU 2021-01 also adds implementation guidance to clarify which optional expedients in ASC 848 may be applied to derivative instruments that do not reference LIBOR or a reference rate that is expected to be discontinued, but that are being modified as a result of the discounting transition. Currently, the Company does not anticipate the need to modify any existing debt agreements as a result of reference rate reform in the current year. If any modification is executed as a result of reference rate reform, the Company will elect the optional practical expedient under ASU 2020-04 and 2021-01, which allows entities to account for the modification as if the modification was not substantial. As a result, the implementation of this guidance is not expected to have an effect on the Company’s consolidated financial statements. Recently Issued Accounting Pronouncements In March 2022, the FASB issued ASU 2022-01 Derivatives and Hedging (Topic 815) Fair Value Hedging—Portfolio Layer Method . The amendments in this Update allow non-prepayable financial assets also to be included in a closed portfolio hedged using the portfolio layer method. That expanded scope permits an entity to apply the same portfolio hedging method to both prepayable and non-prepayable financial assets, thereby allowing consistent accounting for similar hedges. The guidance in the ASU is effective for all periods beginning after December 15, 2022 with early application permitted and may be applied prospectively. The Company does not currently utilize the portfolio layer method. As a result, the implementation of this guidance is not expected to have a material effect on the Company’s consolidated financial statements. In March 2022, the FASB issued ASU 2022-02 Financial Instruments—Credit Losses (Topic 326) Troubled Debt Restructurings and Vintage Disclosures . Rather than applying the recognition and measurement guidance for Troubled Debt Restructurings ("TDRs"), an entity must apply the loan refinancing and restructuring guidance in ASC 310-20-35-9 through 35-11 to determine whether a modification results in a new loan or a continuation of an existing loan. In addition, this Update requires that an entity disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20, Financial Instruments—Credit Losses—Measured at Amortized Cost . The guidance in the ASU is effective for all periods beginning after December 15, 2022 with early application permitted and may be applied prospectively. The Company does not currently have any financial instruments that meet the definition of a TDR. As a result, the implementation of this guidance is not expected to have a material effect on the Company’s consolidated financial statements. In June 2022, the FASB issued ASU 2022-03 Fair Value Measurement (Topic 820)—Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions . The guidance in this update clarifies how the fair value of equity securities subject to contractual sale restrictions is determined, and amends ASC 820 to clarify that a contractual sale restriction should not be considered in measuring fair value. It also requires entities with investments in equity securities subject to contractual sale restrictions to disclose certain qualitative and quantitative information about such securities. The guidance in the ASU is effective for all periods beginning after December 15, 2023 with early application permitted and may be applied prospectively. The Company's investment in Albertsons is subject to a contractual sale restriction, however, the Company does not consider this sale restriction in measuring its fair value ( Note 8 ). As a result, the implementation of this guidance is not expected to have an effect on the Company’s consolidated financial statements.
Lease Intangibles	Upon acquisitions of real estate ( Note 2 ), the Company assesses the fair value of acquired assets (including land, buildings and improvements, and identified intangibles such as above- and below-market leases, including below-market options and acquired in-place leases) and assumed liabilities. The lease intangibles are amortized over the remaining terms of the respective leases, including option periods where applicable.
Earnings Per Common Share	Basic earnings per Common Share is computed by dividing net income attributable to Common Shareholders by the weighted-average Common Shares outstanding ( Note 10 ). During the periods presented, the Company had unvested LTIP Units which provide for non-forfeitable rights to dividend equivalent payments. Accordingly, these unvested LTIP Units are considered participating securities and are included in the computation of basic earnings per Common Share pursuant to the two-class method. Diluted earnings per Common Share reflects the potential dilution of the conversion of obligations and the assumed exercises of securities including the effects of Restricted Share Units issued under the Company’s Share Incentive Plans ( Note 13 ). The effect of such shares is excluded from the calculation of earnings per share when anti-dilutive as indicated in the table below. The effect of the conversion of Common OP Units is not reflected in the computation of basic and diluted earnings per share, as they are exchangeable for Common Shares on a one -for-one basis . The income allocable to such units is allocated on this same basis and reflected as noncontrolling interests in the accompanying consolidated financial statements. As such, the assumed conversion of these units would have no net impact on the determination of diluted earnings per share.

Pursuant to the entity’s operating agreement, the venture partner has a one-time right to put its 50.01 % interest in the entity (the "Williamsburg NCI", which is further described in Note 8 ) to the Company for fair value at a future date. Given the preferred rate of return of the Company embedded in its equity interests and the accruing debt senior to the equity, the Company did not attribute any initial redemption value to the Williamsburg NCI and recognized a bargain purchase gain of $ 1.2 million, which is included in Realized and unrealized holding (losses) gains on investments and other in the consolidated statements of operations. b) The Henderson Avenue Portfolio comprises 14 operating retail assets, one residential building and two development and redevelopment sites.

[1] The entity was previously accounted for as an equity method investment until an affiliate of Fund III acquired the venture partner's interest in a foreclosure action. Fund III now indirectly owns 100% of the entity and consolidates it ( Note 4 ). The Henderson Avenue Portfolio comprises 14 operating retail assets, one residential building and two development and redevelopment sites. The Williamsburg Collection entity is a variable interest entity and the Company consolidates the entity because it is the entity's primary beneficiary. The Company invested $ 2.8 million in its 49.99 % equity interest and, through a separate lending subsidiary, provided a $ 64.1 million first mortgage loan and a $ 30.9 million mezzanine loan to subsidiaries of the venture (such equity and loans have been eliminated in consolidation). Pursuant to the entity’s operating agreement, the venture partner has a one-time right to put its 50.01 % interest in the entity (the "Williamsburg NCI", which is further described in Note 8 ) to the Company for fair value at a future date. Given the preferred rate of return of the Company embedded in its equity interests and the accruing debt senior to the equity, the Company did not attribute any initial redemption value to the Williamsburg NCI and recognized a bargain purchase gain of $ 1.2 million, which is included in Realized and unrealized holding (losses) gains on investments and other in the consolidated statements of operations.
