Organization Organization
Equity Commonwealth, or the Company, is a real estate investment trust, or REIT, formed in 1986 under the laws of the State of Maryland. Our business is primarily the ownership and operation of office properties in the United States.
The Company operates in an umbrella partnership real estate investment trust, or UPREIT, and conducts substantially all of its activities through EQC Operating Trust, a Maryland real estate investment trust, or the Operating Trust. The Company beneficially owned, 99.86% of the outstanding shares of beneficial interest, designated as units, in the Operating Trust, or OP Units, as of December 31, 2024, and the Company is the sole trustee of the Operating Trust.  As the sole trustee, the Company generally has the power under the declaration of trust of the Operating Trust to manage and conduct the business of the Operating Trust, subject to certain limited approval and voting rights of other holders of OP Units.
As of December 31, 2024, our portfolio consisted of one property (one building), with 0.7 million square feet, and we had $160.5 million of cash and cash equivalents. The numbers of buildings and square feet are unaudited.

Plan of Sale Plan of Sale
On October 2, 2024, the Company filed a definitive proxy statement, or the Definitive Proxy, with the U.S. Securities and Exchange Commission, or SEC, related to a Special Meeting of Shareholders, or the Special Shareholder Meeting, for the following purposes: (i) to consider and vote upon the Plan of Sale and Dissolution of the Company, or the Plan of Sale, including the wind-down and complete liquidation of the Company, and the dissolution and termination of the Company, including the establishment of a Liquidating Entity (as defined in the Definitive Proxy), and (ii) on an advisory, non-binding basis, to consider and vote upon compensation that may become payable by the Company to its named executive officers in connection with the Plan of Sale, or the Executive Compensation Proposal. The Plan of Sale, which the Company’s Board of Trustees determined was in the best interests of the Company and its shareholders, authorizes the Company to sell all of its remaining properties, wind-down the Company’s affairs and distribute the net proceeds to shareholders. At the special shareholder meeting held on November 12, 2024, the Company’s shareholders approved both proposals with: (i) 85.5% of outstanding shares, and 99% of votes cast, in favor of the Plan of Sale proposal (two-thirds of outstanding shares required for approval), and (ii) 86.7% of votes cast in favor of the Executive Compensation Proposal (majority of votes cast required for approval).
The Company expects any future liquidity to its shareholders will be provided in the form of liquidating distributions. The Company anticipates making all liquidating distributions to its shareholders prior to the liquidation and dissolution of the Company and the establishment of a Liquidating Entity to pay any remaining liabilities. The Company can provide no assurances as to the ultimate amount or timing of its liquidating distributions or the timing of the complete liquidation and dissolution of the Company; however, the Company anticipates paying its final liquidating distribution and dissolving within six months of completion of the sale of its final property, which occurred on February 25, 2025.
The Plan of Sale authorizes the Company to sell its remaining properties without further shareholder approval, pay or establish a reserve fund for all actual and contingent liabilities, distribute net proceeds to shareholders, and wind-down the Company’s affairs, including the complete liquidation and dissolution of the Company. The Plan of Sale also authorizes the Board to establish or convert into a Liquidating Entity, which we anticipate, but cannot be certain, will occur after our final liquidating distribution is made.
Upon establishing or converting to the Liquidating Entity, our shareholders will receive non-transferable interests in the Liquidating Entity in proportion to the number of common shares owned by such shareholders. The purpose of the Liquidating Entity will be to pay any remaining liabilities and distribute any remaining proceeds to the holders of the interests in the Liquidating Entity.
The Company expects to comply with the requirements necessary to continue to qualify as a REIT through its liquidation and dissolution, or until such time as any remaining assets are transferred to a Liquidating Entity; provided, however, that the Board may elect to terminate the Company’s status as a REIT if it determines that such termination would be in the best interest of the shareholders.
Liabilities for Estimated Costs in Excess of Estimated Receipts During Liquidation
The liquidation basis of accounting requires the Company to estimate net cash flows from operations and to accrue all costs associated with implementing and completing the Plan of Sale. As of December 31, 2024, the Company estimated that it will have costs in excess of estimated receipts during the liquidation process. These amounts can vary significantly due to, among other things, estimates of tenant improvement costs and capital expenditures, the timing and amounts associated with discharging known and contingent liabilities and the costs associated with the winding down of operations. These costs are estimated and are anticipated to be paid out over the liquidation period which is estimated to be complete by September 30, 2025, however, no assurances can be provided that this date will be met.
Upon transition to the liquidation basis of accounting on November 1, 2024, the Company accrued the following revenues and expenses expected to be incurred during liquidation (in thousands):

Net Assets In Liquidation
There were 107,335,177 common shares outstanding and 873,406 unvested restricted stock units at target, prior to any shares expected to be surrendered to satisfy statutory tax withholding obligations in connection with the vesting of such common shares, at December 31, 2024 (See Note 11). The net assets in liquidation as of December 31, 2024 were $178.9 million. Net assets in liquidation include projections of costs and expenses to be incurred during the estimated period required to complete the Plan of Sale. There is inherent uncertainty with these estimates and projections, and they could change materially based on, among other things, changes in the underlying assumptions of the projected cash flows. Cumulative liquidating distributions paid to common shareholders will include the $2.0 billion ($19.00 per common share) paid prior to December 31, 2024 plus any future distribution of our net assets in liquidation.
The decrease from total equity under the going concern basis of accounting as of October 31, 2024 to net assets in liquidation under the liquidation basis of accounting as of November 1, 2024 is primarily due to the liability for estimated costs in excess of estimated receipts during liquidation (See Note 4), the increase in estimated net realizable value of real estate and the write-off of assets and liabilities.

Accounting Policies [Abstract]  
Summary of Significant Accounting Policies Summary of Significant Accounting Policies
The accounting policies and practices related to real estate properties discussed below are applicable to any real estate properties owned for the then-applicable period.
Principles of Consolidation and Basis of Presentation    
The accompanying consolidated financial statements and notes thereto have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP, as contained within the Financial Accounting Standards Board, or FASB,
Accounting Standards Codification, or ASC, including Subtopic 205-30, “Liquidation Basis of Accounting,” as indicated, and
the rules and regulations of the SEC.
Pursuant to the Company’s shareholders’ approval of the Plan of Sale on November 12, 2024, the Company adopted the liquidation basis of accounting as of and for the periods subsequent to November 1, 2024 (as the approval of the Plan of Sale by the Company’s shareholders became imminent in early November 2024 based on the results of the Company’s solicitation of proxies from its shareholders for their approval of the Plan of Sale). Accordingly, on November 1, 2024, assets were adjusted to their estimated net realizable value, or liquidation value, which represents the estimated amount of cash or other consideration that the Company expected to realize through the disposal of assets. The liquidation values of the Company’s real estate properties are presented on a net realizable value basis. Liabilities are carried at their contractual amounts due or estimated settlement amounts.
The Company accrues costs and revenues that it expects to incur and earn as it carries out its liquidation activities through the end of the projected liquidation period to the extent it has a reasonable basis for estimation. Estimated costs expected to be incurred through the end of the liquidation period include budgeted property expenses and corporate overhead, costs to dispose of its real estate property, costs associated with satisfying known and contingent liabilities and other costs associated with the winding down and dissolution of the Company. Revenues are based on in place leases. These amounts are classified as a liability for estimated costs in excess of estimated receipts during liquidation on the consolidated statement of net assets. Actual costs and income may differ from amounts reflected in the financial statements because of the inherent uncertainty in estimating future events. These differences may be material. See Note 2, “Plan of Sale” and Note 4, “Liabilities for Estimated Costs in Excess of Estimated Receipts During Liquidation” for further discussion.
Actual costs incurred but unpaid prior to the Company’s adoption of the liquidation basis of accounting on November 1, 2024, are included in accounts payable and accrued expenses and distributions payable on the consolidated statement of net assets. All our liabilities under either the going concern basis of accounting or the liquidation basis of accounting are derecognized when we pay the obligation or when we are legally released from being the primary obligor under the liability.
Net assets in liquidation represents the remaining estimated liquidation value available to shareholders upon liquidation. Due to the uncertainty in the estimated cash flows from operations and the time required to complete the Plan of Sale, actual liquidation costs and sale proceeds may differ materially from the amounts estimated.
As a result of the change to the liquidation basis of accounting, the Company no longer presents a consolidated balance sheet, a consolidated statement of operations, a consolidated statement of equity or a consolidated statement of cash flows subsequent to October 31, 2024. These statements are only presented for prior year periods. The consolidated financial statements include our investments in 100% owned subsidiaries and majority owned subsidiaries that are controlled by us. References to we, us, our and the Company, refer to Equity Commonwealth and its consolidated subsidiaries, unless the context indicates otherwise. All intercompany transactions and balances have been eliminated.
Dollar amounts presented may be approximate. Share amounts are presented in whole numbers, except where noted.
Use of Estimates    
Preparation of these financial statements in conformity with GAAP requires us to make estimates and assumptions that may affect the amounts reported in these financial statements and related notes. The Company is required to estimate all costs and revenue it expects to incur and earn through the end of liquidation including the estimated amount of cash it expects to collect on disposal of its assets and the estimated costs to dispose of its assets. All of the estimates and evaluations are susceptible to change and actual results could differ from these estimates.
Real Estate Properties
Liquidation Basis of Accounting
As of November 1, 2024, the Company’s real estate was adjusted to its estimated net realizable value, or liquidation value, to reflect the change to the liquidation basis of accounting. The liquidation value represents the estimated amount of cash or other consideration that the Company expected to realize through the disposal of its assets. The Company estimated the liquidation value of its real estate based on a contractual purchase price for the property. The liquidation value of the Company’s real estate is presented on an undiscounted basis and real estate is no longer depreciated. Subsequent to November 1, 2024, all changes in the estimated liquidation value of the real estate is reflected as a change to the Company’s net assets in liquidation. Costs to sell the property such as credits for capital costs, contractual lease obligations and rent abatements are included in Liabilities for estimated costs in excess of estimated receipts during liquidation.
Going Concern Basis    
We record real estate properties at cost. We depreciate real estate investments on a straight-line basis over estimated useful lives of up to 40 years for buildings and improvements, and up to 12 years for personal property.
Each time we enter into a new lease, or materially modify an existing lease, we evaluate its classification as either a finance or operating lease. The classification of a lease as finance or operating affects the carrying value of a property, as well as our recognition of rental payments as revenue. These evaluations require us to make estimates of, among other things, the remaining useful life and fair market value of a leased property, appropriate discount rates and future cash flows.
We allocate the consideration paid for our properties among land, buildings and improvements and, for properties that qualify as acquired businesses under the Business Combinations Topic of the FASB Accounting Standards Codification, or ASC, to identified intangible assets and liabilities, consisting of the value of above market and below market leases, the value of acquired in place leases and the value of tenant relationships. Purchase price allocations and the determination of useful lives are based on our estimates and, under some circumstances, studies from independent real estate appraisal firms to provide market information and evaluations that are relevant to our purchase price allocations and determinations of useful lives; however, we are ultimately responsible for the purchase price allocations and determination of useful lives.
We allocate the consideration to land, buildings and improvements based on a determination of the fair values of these assets assuming the property is vacant. We determine the fair value of a property using methods that we believe are similar to those used by independent appraisers. Purchase price allocations for above market and below market leases are based on the estimated present value (using an interest rate which reflects our assessment of the risks associated with the leases acquired) of the difference between (1) the contractual amounts to be paid pursuant to the acquired in place leases and (2) our estimate of fair market lease rates for the corresponding leases, measured over a period equal to the remaining non-cancelable terms of the respective leases. Purchase price allocations to acquired in place leases and tenant relationships are determined as the excess of (1) the purchase price paid for a property after adjusting existing in place leases to estimated market rental rates over (2) the estimated fair value of the property as if vacant. We aggregate this value between acquired in place lease values and tenant relationships based on our evaluation of the specific characteristics of each tenant's lease; however, the value of tenant relationships has not been separated from acquired in place lease value for our properties because we believe such value and related amortization expense is immaterial for acquisitions reflected in our historical financial statements. We consider certain factors in performing these analyses including estimates of carrying costs during the expected lease up periods, including real estate taxes, insurance and other operating income and expenses and costs to execute similar leases in current market conditions, such as leasing commissions, legal and other related costs. If we believe the value of tenant relationships is material in the future, those amounts will be separately allocated and amortized over the estimated lives of the relationships. We recognize the excess, if any, of the consideration paid over amounts allocated to land, buildings and improvements and identified intangible assets and liabilities as goodwill and we recognize gains if amounts allocated exceed the consideration paid.
We amortize capitalized above market lease values as a reduction to rental income over the remaining terms of the respective leases. We amortize capitalized below market lease values as an increase to rental income over the remaining terms of the respective leases. We amortize the value of acquired in place leases exclusive of the value of above market and below market acquired in place leases to expense over the remaining terms of the respective leases. If a lease is terminated prior to its stated expiration, the unamortized lease intangibles relating to that lease is written off.
We review our properties for impairment quarterly, or whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. Impairment indicators may include our decision to dispose of an asset before the end of its estimated useful life, declining tenant occupancy, lack of progress releasing vacant space, tenant bankruptcies, low long-term prospects for improvement in property performance, weak or declining tenant profitability, and cash flow or liquidity. When indicators of potential impairment are present that suggest that the carrying amounts of real estate assets may not be recoverable, we assess the recoverability of these assets by determining whether the respective carrying values will be recovered through the estimated undiscounted future operating cash flows expected from the use of the assets and their eventual disposition. The determination of undiscounted cash flow includes consideration of many factors including income to be earned from the investment over our anticipated hold period, holding costs (exclusive of interest), estimated selling prices, and prevailing economic and market conditions. In the event that such expected undiscounted future cash flows do not exceed the carrying values, we estimate the fair value of the assets and record an impairment charge equal to the amount by which the carrying value exceeds the estimated fair value. Estimated fair values are calculated based on the following information, (i) recent third party estimates of market value, (ii) market prices for comparable properties, or (iii) the present value of future cash flows. During the ten months ended October 31, 2024, we recorded a loss on asset impairment of $49.3 million. During the years ended December 31, 2023 and 2022 we did not record any loss on asset impairment.
When we classify properties as held for sale, we discontinue the recording of depreciation expense and estimate their fair value less costs to sell. If we determine that the carrying value for these properties exceed their estimated fair value less costs to sell, we record a loss on asset impairment. As of December 31, 2023, we did not have any properties classified as held for sale.
Certain of our formerly owned real estate assets contained hazardous substances, including asbestos. We believe any asbestos in our former buildings is contained in accordance with current regulations. If the asbestos is removed or these properties are renovated or demolished, certain environmental regulations govern the manner in which the asbestos must be handled and removed. We do not believe that there are other environmental conditions or issues at any of our former properties that have had or will have a material adverse effect on us. However, no assurances can be given that we will not be required to incur costs in the future in connection with the remediation of contamination or compliance with environmental, health and safety laws that will have a material adverse effect on our business or financial condition. As December 31, 2024 and 2023, we did not have any accrued environmental remediation costs.
Cash and Cash Equivalents    
Our cash and cash equivalents consist of cash maintained in time deposits, depository accounts and money market accounts.  We regularly monitor the credit ratings of the financial institutions holding our deposits to minimize our exposure to credit risk.  Throughout the year, we have cash balances in excess of federally insured limits deposited with various financial institutions. We do not believe we are exposed to any significant credit risk on cash and cash equivalents.
Other Assets, Net
Going Concern Basis
Other assets consist principally of deferred leasing costs, capitalized lease incentives and prepaid property operating expenses. Deferred leasing costs are amortized on a straight-line basis over the terms of the respective leases. Capitalized lease incentives are amortized on a straight-line basis against rental income over the terms of the respective leases.
Accrued Liquidation Costs
Liquidation Basis of Accounting
In accordance with the liquidation basis of accounting, the Company has recorded certain estimated liquidation costs to the extent it has a reasonable basis for estimation. These consist of compensation expense, legal fees, accounting fees, other professional service fees and other dissolution costs. These amounts are included in Liabilities for estimated costs in excess of estimated receipts during liquidation on the consolidated statement of net assets. See Note 4.
Revenue Recognition
Liquidation Basis of Accounting
Under the liquidation basis of accounting, the Company has accrued all income that it expects to earn through the completion of its liquidation to the extent it has a reasonable basis for estimation. Revenue from tenants is estimated based on the contractual in place leases through the anticipated disposition date of the property. These amounts are presented net of
estimated expenses and other liquidation costs and are classified in liabilities for estimated costs in excess of estimated receipts during liquidation on the consolidated statement of net assets.
Going Concern Basis    
Rental revenue from operating leases, which includes rent concessions (including free rent and other lease incentives) and scheduled increases in rental rates during the lease term, represents the lease component and is recognized on a straight-line basis over the life of the lease agreements. We defer the recognition of contingent rental income, such as percentage rents, until the specific targets that trigger the contingent rental income are achieved. Rental revenue also includes non-lease components such as property level operating expenses reimbursed by our tenants and other incidental revenues, which are recorded as expenses are incurred. We concluded that the timing and pattern of transfer for non-lease components and the associated lease component are the same. We determined that the predominant component was the lease component and we have elected to account for and present the lease component and non-lease component of our leases as a single component in Rental revenue in our consolidated statements of operations in accordance with FASB Topic 842.
Lessee Lease Classification
Going Concern Basis
We classify leases as either finance or operating in accordance with FASB Topic 842, Leases. This classification determines whether the related expense is recognized based on an effective interest method for finance leases or on a straight-line basis over its life for operating leases. Additionally, lessees are required to record a right-of-use asset and lease liability for all leases with a term greater than 12 months. We have made an accounting policy election as permitted under ASC 842 to forgo recognition of a right-of-use asset and lease liability for short-term leases of less than 12 months.
Earnings Per Common Share    
Going Concern Basis
Earnings per common share, or EPS, is computed using the weighted average number of common shares outstanding during the period. Diluted EPS reflects the potential dilution that could occur if our series D convertible preferred shares, our restricted share units, or RSUs, or beneficial interests in the Operating Trust, or LTIP Units, were converted into our common shares, which could result in a lower EPS amount. The effect of our series D convertible preferred shares on net income attributable to common shareholders is anti-dilutive for the ten months ended October 31, 2024 and years ended December 31, 2023 and 2022.
Reclassifications    
Reclassifications have been made to the prior years' financial statements and notes to conform to the current year's presentation.
Legal Matters
We are or may become a party to various legal proceedings. We are not currently involved in any litigation nor, to our knowledge, is any litigation threatened against us where the outcome would, in our judgment based on information currently available to us, have a material adverse effect on the Company.
Income Taxes    
We are a REIT under the Internal Revenue Code of 1986, as amended, and are generally not subject to federal and state income taxes provided we distribute our taxable income to our shareholders and meet other requirements for qualifying as a REIT. We are also subject to certain state and local taxes without regard to our REIT status.
Going Concern Basis
The Income Taxes Topic of the FASB ASC prescribes how we should recognize, measure and present in our financial statements uncertain tax positions that have been taken or are expected to be taken in a tax return. Deferred tax assets are recognized to the extent that it is “more likely than not” that a particular tax position will be sustained upon examination or audit. To the extent the “more likely than not” standard has been satisfied, the benefit associated with a tax position is measured as the largest amount that has a greater than 50% likelihood of being realized upon settlement. We classify interest and penalties related to uncertain tax positions, if any, in our financial statements as a component of general and administrative expense.
New Accounting Pronouncements
In November 2023, the FASB issued Accounting Standards Update, or ASU, 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which improves the disclosures about a public entity's reportable segments and addresses requests from investors for additional, more detailed information about a reportable segment's expenses. This update is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. We adopted ASU 2023-07 on January 1, 2024, and the adoption did not have a material impact on our consolidated financial statements.
In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which enhances the transparency and decision usefulness of income tax disclosures. This update is effective for annual periods beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. We do not expect the adoption of ASU 2023-09 to have a material impact on our consolidated financial statements.

Net Assets In Liquidation Plan of Sale
On October 2, 2024, the Company filed a definitive proxy statement, or the Definitive Proxy, with the U.S. Securities and Exchange Commission, or SEC, related to a Special Meeting of Shareholders, or the Special Shareholder Meeting, for the following purposes: (i) to consider and vote upon the Plan of Sale and Dissolution of the Company, or the Plan of Sale, including the wind-down and complete liquidation of the Company, and the dissolution and termination of the Company, including the establishment of a Liquidating Entity (as defined in the Definitive Proxy), and (ii) on an advisory, non-binding basis, to consider and vote upon compensation that may become payable by the Company to its named executive officers in connection with the Plan of Sale, or the Executive Compensation Proposal. The Plan of Sale, which the Company’s Board of Trustees determined was in the best interests of the Company and its shareholders, authorizes the Company to sell all of its remaining properties, wind-down the Company’s affairs and distribute the net proceeds to shareholders. At the special shareholder meeting held on November 12, 2024, the Company’s shareholders approved both proposals with: (i) 85.5% of outstanding shares, and 99% of votes cast, in favor of the Plan of Sale proposal (two-thirds of outstanding shares required for approval), and (ii) 86.7% of votes cast in favor of the Executive Compensation Proposal (majority of votes cast required for approval).
The Company expects any future liquidity to its shareholders will be provided in the form of liquidating distributions. The Company anticipates making all liquidating distributions to its shareholders prior to the liquidation and dissolution of the Company and the establishment of a Liquidating Entity to pay any remaining liabilities. The Company can provide no assurances as to the ultimate amount or timing of its liquidating distributions or the timing of the complete liquidation and dissolution of the Company; however, the Company anticipates paying its final liquidating distribution and dissolving within six months of completion of the sale of its final property, which occurred on February 25, 2025.
The Plan of Sale authorizes the Company to sell its remaining properties without further shareholder approval, pay or establish a reserve fund for all actual and contingent liabilities, distribute net proceeds to shareholders, and wind-down the Company’s affairs, including the complete liquidation and dissolution of the Company. The Plan of Sale also authorizes the Board to establish or convert into a Liquidating Entity, which we anticipate, but cannot be certain, will occur after our final liquidating distribution is made.
Upon establishing or converting to the Liquidating Entity, our shareholders will receive non-transferable interests in the Liquidating Entity in proportion to the number of common shares owned by such shareholders. The purpose of the Liquidating Entity will be to pay any remaining liabilities and distribute any remaining proceeds to the holders of the interests in the Liquidating Entity.
The Company expects to comply with the requirements necessary to continue to qualify as a REIT through its liquidation and dissolution, or until such time as any remaining assets are transferred to a Liquidating Entity; provided, however, that the Board may elect to terminate the Company’s status as a REIT if it determines that such termination would be in the best interest of the shareholders.
Liabilities for Estimated Costs in Excess of Estimated Receipts During Liquidation
The liquidation basis of accounting requires the Company to estimate net cash flows from operations and to accrue all costs associated with implementing and completing the Plan of Sale. As of December 31, 2024, the Company estimated that it will have costs in excess of estimated receipts during the liquidation process. These amounts can vary significantly due to, among other things, estimates of tenant improvement costs and capital expenditures, the timing and amounts associated with discharging known and contingent liabilities and the costs associated with the winding down of operations. These costs are estimated and are anticipated to be paid out over the liquidation period which is estimated to be complete by September 30, 2025, however, no assurances can be provided that this date will be met.
Upon transition to the liquidation basis of accounting on November 1, 2024, the Company accrued the following revenues and expenses expected to be incurred during liquidation (in thousands):
As of November 1, 2024
Rental income$9,443 
Interest income13,006 
Property operating expenses(4,076)
General and administrative expenses(32,212)

Capital expenditures and tenant lease obligations(8,808)
Liquidation transaction costs(44,230)
Liabilities for estimated costs in excess of estimated receipts during liquidation$(190,171)
The change in the liabilities for estimated costs in excess of estimated receipts during liquidation as of December 31, 2024 is as follows (in thousands):

(1) Liquidation transaction costs primarily include severance expenses, advisory fees and other professional services expenses.
Net Assets In Liquidation
There were 107,335,177 common shares outstanding and 873,406 unvested restricted stock units at target, prior to any shares expected to be surrendered to satisfy statutory tax withholding obligations in connection with the vesting of such common shares, at December 31, 2024 (See Note 11). The net assets in liquidation as of December 31, 2024 were $178.9 million. Net assets in liquidation include projections of costs and expenses to be incurred during the estimated period required to complete the Plan of Sale. There is inherent uncertainty with these estimates and projections, and they could change materially based on, among other things, changes in the underlying assumptions of the projected cash flows. Cumulative liquidating distributions paid to common shareholders will include the $2.0 billion ($19.00 per common share) paid prior to December 31, 2024 plus any future distribution of our net assets in liquidation.
The decrease from total equity under the going concern basis of accounting as of October 31, 2024 to net assets in liquidation under the liquidation basis of accounting as of November 1, 2024 is primarily due to the liability for estimated costs in excess of estimated receipts during liquidation (See Note 4), the increase in estimated net realizable value of real estate and the write-off of assets and liabilities.

Common Share Repurchases:
On August 24, 2015, our Board of Trustees approved a common share repurchase program. On March 15, 2022, our Board of Trustees authorized the repurchase of up to $150.0 million of our outstanding common shares through June 30, 2023. On June 13, 2023, our Board of Trustees authorized the repurchase of up to $150.0 million of our outstanding common shares from July 1, 2023 through June 30, 2024. On June 18, 2024, our Board of Trustees authorized the repurchase of up to $150.0 million of our outstanding common shares from July 1, 2024 through June 30, 2025.
During the year ended December 31, 2024, we did not repurchase any shares. During the year ended December 31, 2023, we repurchased and retired 3,018,411 of our common shares at a weighted average price of $18.78 per share, for a total investment of $56.7 million. During the year ended December 31, 2022, we repurchased and retired 6,110,646 of our common shares at a weighted average dividend adjusted price of $24.64 per share, for a total investment of $155.5 million. The share repurchases in 2022 discussed in this paragraph were completed prior to the special, one-time cash distributions in that year, which was in the amount of $1.00 per common share/unit paid on October 18, 2022. As of December 31, 2024, we had $150.0 million of remaining availability under our share repurchase program, which expires on June 30, 2025.
During the years ended December 31, 2024, 2023 and 2022, certain of our employees and former employees surrendered 162,599, 134,193 and 160,506 common shares owned by them, respectively, to satisfy their statutory tax withholding obligations in connection with the vesting of such common shares pursuant to our equity compensation plans.
Common Share and Unit Distributions:
On November 15, 2024, the Company announced that its Board of Trustees authorized an initial cash liquidating distribution of $19.00 per common share which was paid on December 6, 2024 to shareholders of record on November 25, 2024. On December 6, 2024, we paid this distribution to such shareholders in the aggregate amount of $2.0 billion. On November 15, 2024, the Company also updated the estimated aggregate shareholder liquidating distribution range of $19.50 to $21.00 per common share disclosed in its Definitive Proxy to an estimated aggregate shareholder liquidating distribution range of $20.00 to $21.00 per common share. On February 27, 2025, following the February 25, 2025 closing of the sale of 1225 Seventeenth Street in Denver, CO, the Company updated the aggregate shareholder liquidating distribution to an estimated range of $20.55 to $20.70 per common share.
On February 13, 2023, our Board of Trustees declared a special, one-time cash distribution of $4.25 per common share/unit to shareholders/unitholders of record on February 23, 2023. On March 9, 2023, we paid this distribution to such shareholders/unitholders in the aggregate amount of $468.3 million.
On September 8, 2022, our Board of Trustees declared a special, one-time cash distribution of $1.00 per common share/unit to shareholders/unitholders of record on September 29, 2022. On October 18, 2022, we paid this distribution to such shareholders/unitholders in the aggregate amount of $111.0 million.
In February 2024, 2023 and 2022, the number of earned awards for recipients of the Company’s restricted stock units and market-based LTIP Units granted in January 2021, 2020, and 2019, respectively, was determined. Pursuant to the terms of such wards, we paid one-time catch-up cash distributions to these recipients in the aggregate amounts of $2.0 million, $1.8 million, and $1.5 million, in February 2024, 2023, and 2022, respectively, for distributions to common shareholders and unitholders declared by our Board of Trustees during such awards’ performance measurement period.
The following characterizes distributions paid per common share for the years ended December 31, 2024, 2023, and 2022:

(1)Liquidation distributions are first applied against shareholder tax basis, but not below zero. To the extent liquidation distributions exceed shareholder tax basis, such excess is taxable gain in the year of receipt. To the extent liquidation distributions are less than shareholder tax basis, any loss will be recognized in the year the final liquidation distribution is received.
Series D Preferred Shares:
On November 12, 2024, in connection with the Plan of Sale, the Company announced that its Board of Trustees authorized payment of the liquidation preference to the holders of shares of the Company’s 6.50% Series D Cumulative Convertible Preferred Shares of beneficial interest, par value $0.01 per share (the Series D Preferred Shares). A payment of $25.00 per Series D Preferred Share, plus accrued dividends of $0.08576 per Series D Preferred Share, for the period from November 15, 2024 through December 3, 2024 (the Payment Date), was paid on the Payment Date to shareholders as of the Payment Date. This payment of $123.3 million paid all amounts due and owing the holders of the Company’s Series D Preferred Shares in connection with the previously disclosed shareholder approval of the Plan of Sale and, in accordance with the terms thereof, the Series D Preferred Shares have no right or claim to any of the remaining assets of the Company.
In conjunction with the payment of the liquidation preference, the Series D Preferred Shares were suspended from the NYSE before market open on the Payment Date. A Form 25 was filed with the SEC to effect the withdrawal of the listing of the Series D Preferred Shares from the NYSE.
With respect to our historical going concern financial statements, each of our 4,915,196 series D cumulative convertible preferred shares accrued dividends of $1.625, or 6.50% per annum of the liquidation amount, payable in equal quarterly payments. Our series D preferred shares were convertible, at the holder’s option, into our common shares at a conversion rate of 0.8204 common shares per series D preferred share, which is equivalent to a conversion price of $30.47 per common share, or 4,032,427 additional common shares at October 31, 2024. The conversion rate changed from 0.6846 to 0.8204 common shares per series D preferred share effective February 24, 2023 as a result of the common share distribution declared by our Board of Trustees in 2023. The conversion rate changed from 0.6585 to 0.6846 common shares per series D preferred share effective September 30, 2022 as a result of the common share distribution declared by our Board of Trustees in 2022. Prior to the liquidation preference payment, holders of 1,265 Series D preferred shares converted their Series D preferred shares to 1,037 common shares.
Preferred Share Distributions:
Under our governing documents and Maryland law, distributions to our shareholders are to be authorized and declared by our Board of Trustees. In 2024, our Board of Trustees declared distributions on our series D preferred shares to date as follows:

Noncontrolling Interest [Abstract]  
Noncontrolling Interest Noncontrolling Interest
Noncontrolling interest represents the portion of the OP Units not beneficially owned by the Company. The ownership of an OP Unit and a common share of beneficial interest have essentially the same economic characteristics. Distributions with respect to OP Units will generally mirror distributions with respect to the Company’s common shares. Unitholders (other than the Company) generally have the right, commencing six months from the date of issuance of such OP Units, to cause the Operating Trust to redeem their OP Units in exchange for cash or, at the option of the Company, common shares of the Company on a one-for-one basis. As sole trustee, the Company has the sole discretion to elect whether the redemption right will be satisfied by the Company in cash or the Company’s common shares. As a result, the Noncontrolling interest is classified as permanent equity. As of December 31, 2024, the portion of the Operating Trust not beneficially owned by the Company is in the form of OP Units and LTIP Units (see Note 11 for a description of LTIP Units). LTIP Units may be subject to additional vesting requirements.
The following table presents the changes in Equity Commonwealth’s issued and outstanding common shares and units for the year ended December 31, 2024:

The carrying value of the Noncontrolling interest is allocated based on the number of OP Units and LTIP Units in proportion to the number of OP Units and LTIP Units plus the number of common shares. We adjust the Noncontrolling interest balance at the end of each period to reflect the noncontrolling partners’ interest in the net assets of the Operating Trust. Net income is allocated to the Noncontrolling interest in the Operating Trust based on the weighted average ownership percentage during the period. Equity Commonwealth’s weighted average ownership interest in the Operating Trust was 99.84%, 99.69% and 99.75%, respectively, for the years ended December 31, 2024, 2023 and 2022.

As a result, for the years ended December 31, 2023 and 2022, the Operating Trust recognized $200.0 million and $82.0 million taxable gains, respectively, for federal income tax purposes. The gains were distributed by the Company and have no impact on the Company’s provision for income taxes for the years ended December 31, 2023 and 2022.
At December 31, 2024 and 2023, we had federal net operating loss, or NOL, carryforwards of $29 million and $29 million, respectively. These amounts can be used to offset future taxable income, if any. The REIT will be entitled to utilize NOL carryforwards only to the extent that REIT taxable income exceeds our deduction for dividends paid. NOLs arising in
taxable years ending before January 1, 2018 can generally be carried forward 20 years, with no carryforward limitation on NOLs generated after that date. NOL carryforwards of $18 million expire in 2037 and NOL carryforwards of $11 million never expire.

Equity Commonwealth 2015 Omnibus Incentive Plan (2015 Omnibus Plan)
On June 16, 2015, at our 2015 annual meeting of shareholders, our shareholders approved the 2015 Omnibus Plan. The 2015 Omnibus Plan replaced the Equity Commonwealth 2012 Equity Compensation Plan (as amended, the 2012 Plan). The Board of Trustees approved the 2015 Omnibus Plan, subject to shareholder approval, on March 18, 2015 (the Effective Date). On January 26, 2016, the Board of Trustees approved an amendment to the 2015 Omnibus Plan to allow the Compensation Committee (Committee) to authorize in an award agreement a transfer of all or a part of certain equity awards not for value to a “family member” (as defined in the 2015 Incentive Plan). At our annual meeting of shareholders on June 20, 2019, our shareholders approved an amendment to the 2015 Omnibus Plan to increase the number of common shares of beneficial interest authorized thereunder by 2,500,000, and, at our annual meeting of shareholders on June 13, 2023, our shareholders approved an amendment to the 2015 Omnibus Plan to increase the number of common shares of beneficial interest authorized thereunder by 1,650,000 (hereafter, as amended, the 2015 Omnibus Plan). The following description of certain terms of the 2015 Omnibus Plan is qualified in all respects by the terms of the 2015 Omnibus Plan.
Eligibility. Awards may be granted under the 2015 Omnibus Plan to employees, officers and non-employee directors of the Company, its subsidiaries or its affiliates, or consultants and advisors (who are natural persons) providing services to the Company, its subsidiaries or its affiliates, or any other person whose participation in the 2015 Omnibus Plan is determined by the Committee to be in the best interests of the Company.
Term. The 2015 Omnibus Plan terminates automatically ten years after the Effective Date, unless it is terminated earlier by the Board of Trustees.
Shares Available for Issuance. Subject to adjustment as provided in the 2015 Omnibus Plan, the maximum number of common shares of the Company that are available for issuance under the 2015 Omnibus Plan is 7,400,000 shares.
Awards. The following types of awards may be made under the 2015 Omnibus Plan, subject to limitations set forth in the 2015 Omnibus Plan:
· Stock options;
· Stock appreciation rights;
· Restricted stock;
· Restricted stock units;
· Unrestricted stock;
· Dividend equivalent rights;
· Performance shares and other performance-based awards;
· Limited partnership interests in any partnership entity through which the Company conducts or may conduct its business;
· Other equity-based awards; and
· Cash awards.
Recipients of the Company’s restricted shares have the same voting rights as any other common shareholder. During the period of restriction, holders of unvested restricted shares are eligible to receive dividend payments on their shares at the same rate and on the same date as any other common shareholder.  The restricted shares are service based awards and vest over a service period determined by the Committee.
Recipients of the Company’s restricted stock units, or RSUs, are entitled to receive dividends with respect to the common shares underlying the RSUs if and when the RSUs are earned, at which time the recipient will be entitled to receive an amount in cash equal to the aggregate amount of cash dividends that would have been paid in respect to the common shares underlying the recipient’s earned RSUs had such common shares been issued to the recipient on the first day of the performance period. To the extent that an award does not vest, the dividends related to unvested RSUs will be forfeited. The RSUs are market-based awards with a service condition and recipients may earn RSUs based on the Company’s total shareholder return, or TSR, relative to the TSRs of the companies that comprise the Nareit Office Index over a three-year performance period. Following the end of the three-year performance period, the number of earned awards will be determined. The earned awards vest in two
tranches with 50% of the earned award vesting following the end of the performance period on the date the Committee determines the level of achievement of the performance metric and the remaining 50% of the earned award vesting approximately one year thereafter, subject to the grant recipient’s continued employment. Compensation expense for the RSUs is determined using a Monte Carlo simulation model and is recognized ratably from the grant date to the vesting date of each tranche.
LTIP Units are a class of beneficial interests in the Operating Trust that may be issued to employees, officers or trustees of the Operating Trust, the Company or their subsidiaries, or LTIP Units. Time-based LTIP Units have the same general characteristics as restricted shares and market-based LTIP Units have the same general characteristics as RSUs. Each LTIP Unit will convert automatically into an OP Unit on a one-for-one basis when the LTIP Unit becomes vested and its capital account is equalized with the per-unit capital account of the OP Units. Holders of LTIP Units generally will be entitled to receive the same per-unit distributions as the other outstanding OP Units in the Operating Trust, except that market-based LTIP Units will not participate in distributions until expiration of the applicable performance period, at which time any earned market-based LTIP Units generally will become entitled to receive a catch-up distribution for the periods prior to such time.
Administration. The 2015 Omnibus Plan will be administered by the Committee, which will determine all terms and recipients of awards under the 2015 Omnibus Plan.

(1) The table presents the maximum number of shares issued or issuable from outstanding equity awards. RSUs and market-based LTIP Units not earned are the shares market-based award recipients do not receive based on the performance measurement completed at the end of the performance period.
The unvested restricted shares, time based LTIP Units, and RSUs and Market-Based LTIP Units, to the extent they become earned, are scheduled to vest between 2025 and 2028 or upon a change in control of the company if such change in control occurs before their scheduled vesting date. Our Board determined that a change in control occurred on February 25, 2025 as a result of the sale of 1225 Seventeenth Street Plaza, which it determined constituted a sale of substantially all of our assets. Accordingly, equity awards outstanding that remain unvested on February 25, 2025 will vest on an accelerated basis. Compensation expense for the restricted share and time-based LTIP Units through October 31, 2024 was recognized on a straight-line basis over the requisite service period (through their respective scheduled vesting date) for each separately vesting portion of the award.
In December 2024, as part of the Plan of Sale and to facilitate an efficient wind-down of the Company, the Company terminated its various Registration Statements on Form S-8, which were used to register the Company’s common shares reserved for issuance as equity awards pursuant to the 2015 Omnibus Plan. As a result, the Company will not be able to issue additional shares under the 2015 Omnibus Plan with respect to the portion of any outstanding performance-based awards that is
determined to be earned in light of above-target performance. Consequently, on January 27, 2025, the Compensation Committee amended the 2022 Performance-Based Awards granted to our employees who received January 26, 2022 Performance-Based Awards, including our named executive officers, to provide that such awards would be settled in cash as to the portion of the 2022 Performance-Based Awards measured above target, with 50% of such awards vesting on February 4, 2025, when the Compensation Committee approved the performance measurement, and 50% of such awards scheduled to vest on the Measurement Date in February of 2026, subject to the terms and conditions of the applicable award agreements.
The assumptions and fair values for the RSUs and market-based LTIP Units granted for the years ended December 31, 2024, 2023 and 2022 are included in the following table on a per share and unit basis.

During the ten months ended October 31, 2024 and years ended December 31, 2023 and 2022, we recorded $9.1 million, $16.0 million and $11.9 million, respectively, of compensation expense, net of forfeitures, in general and administrative expense for grants to our trustees, employees and an eligible consultant related to our equity compensation plans. Compensation expense recorded during the ten months ended October 31, 2024 and years ended December 31, 2023 and 2022 includes $0.4 million, $5.2 million and $0.4 million, respectively, of accelerated vesting due to staffing reductions in 2024, the passing of our former Chairman in 2023 and staffing reductions in 2022. Forfeitures are recognized as they occur. At December 31, 2024, while 1,406,557 shares/units technically remain available for issuance under the 2015 Omnibus Plan, in light of the termination of various Registration Statements on Form S-8, which were used to register the Company’s common shares reserved for issuance as equity awards pursuant to the 2015 Omnibus Plan, any such shares would not be registered and therefore the Company will not potentially be able to issue any such shares.

Fair Value Disclosures [Abstract]  
Fair Value of Assets and Liabilities Fair Value of Assets and Liabilities
Properties Held for Sale (Going Concern Basis)
Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. A three-level valuation hierarchy exists for disclosures of fair value measurements based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. A financial instrument's categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The three levels are defined below:
Level 1 - Quoted prices in active markets for identical assets or liabilities.
Level 2 - Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
At September 30, 2024, we had classified 1250 H Street, NW, 206 East 9th Street and Bridgepoint Square as held for sale in accordance with ASC 360. As a result of our current estimates of market value less estimated costs to sell, it was necessary to record impairment charges for the ten months ended October 31, 2024 of $49.3 million which includes $16.3 million of impairment related to non-real estate assets. We determined these impairments based on contractual purchase prices for the properties, which are level 2 inputs according to the fair value hierarchy established in ASC 820. We reduced the aggregate carrying values of these properties from $136.9 million to their estimated fair value less estimated costs to sell of $87.6 million. These properties were sold in the fourth quarter of 2024 (See Note 6).
Financial Instruments (Going Concern Basis)
Our financial instruments include our cash and cash equivalents. At December 31, 2024 and 2023, the fair value of these financial instruments was not different from their carrying values.
Other financial instruments that potentially subject us to concentrations of credit risk consist principally of rents receivable. As of December 31, 2024, three individual tenants were responsible for more than 10% of our future minimum lease payments, excluding tenant reimbursement revenue (see Note 6). These tenants, CBRE, Inc., Salesforce.com, Inc., and KPMG, LLP individually accounted for 16.5%, 12.0% and 10.2%, respectively, of our future minimum lease payments, excluding tenant reimbursement revenue.

Segment Information Segment Information
 Our primary business was the ownership and operation of office properties, and we have one reportable segment. One hundred percent of our revenues for the ten months ended October 31, 2024 were from office properties.
We define our segments the basis in which internally reported financial information is regularly reviewed by the chief operating decision maker, or CODM, to analyze financial performance, make decisions, and allocate resources. Our CODM is our Executive Vice President and Chief Operating Officer. Our CODM uses components of net income in the annual budget and forecasting process. The CODM considers budget-to-actual variances on a quarterly basis when making decisions about the allocation of operating and capital resources. Our significant segment expenses include operating expenses and general administrative expenses which are presented on our consolidated statements of operations.

The following discussion includes a description of our related person transactions for the years ended December 31, 2024, 2023 and 2022.
We lease office space for our corporate headquarters from Two North Riverside Plaza Joint Venture Limited Partnership, an entity associated with Equity Group Investments (EGI), a private entrepreneurial investment firm founded by Sam Zell, our former Chairman who passed away on May 18, 2023. Messrs. Helfand and Weinberg continue to be advisors to EGI and certain other members of our team are expected to continue to have limited involvement in its activities.
In December 2021, we entered into a second amendment to our July 2015 lease with Two North Riverside Plaza Joint Venture Limited Partnership to occupy office space on the twentieth and twenty-first floors of Two North Riverside Plaza in Chicago, Illinois. The amendment extended the lease term for one year, through December 31, 2022, with no renewal options, for a lease payment of $0.4 million per year. In December 2022, we entered into a third amendment to the lease extending the lease term for one year, through December 31, 2023, with no renewal options, for a lease payment of $0.4 million per year. In August 2023, we entered into a fourth amendment to the lease extending the lease term for one year, through December 31, 2024, with no renewal options and contracting square feet to the existing space on the twentieth floor, for a lease payment of $0.4 million per year. In April 2024, we entered into a fifth amendment to the lease extending the lease term for two additional years, through December 31, 2026, with no renewal options (as amended by the first through fifth lease amendments, the Two North Office Lease), for a lease payment of $0.4 million per year. The Two North Office Lease allows EQC to terminate the lease early for a termination fee equal to three-months’ base rent.
During the ten months ended October 31, 2024 and years ended December 31, 2023 and 2022, we recognized expenses of $0.3 million, $0.4 million and $0.4 million, respectively, pursuant to the Two North Office Lease. The future minimum lease payments and the early termination fee are $0.4 million and are included in liabilities for estimated costs in excess of estimated receipts during liquidation on the consolidated statement of net assets as of December 31, 2024. As of December 31, 2023, we did not have any amounts due to Two North Riverside Plaza Joint Venture Limited Partnership pursuant to the Two North Office Lease.

Accounting Policies [Abstract]  
Principles of Consolidation and Basis of Presentation
Principles of Consolidation and Basis of Presentation    
The accompanying consolidated financial statements and notes thereto have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP, as contained within the Financial Accounting Standards Board, or FASB,
Accounting Standards Codification, or ASC, including Subtopic 205-30, “Liquidation Basis of Accounting,” as indicated, and
the rules and regulations of the SEC.
Pursuant to the Company’s shareholders’ approval of the Plan of Sale on November 12, 2024, the Company adopted the liquidation basis of accounting as of and for the periods subsequent to November 1, 2024 (as the approval of the Plan of Sale by the Company’s shareholders became imminent in early November 2024 based on the results of the Company’s solicitation of proxies from its shareholders for their approval of the Plan of Sale). Accordingly, on November 1, 2024, assets were adjusted to their estimated net realizable value, or liquidation value, which represents the estimated amount of cash or other consideration that the Company expected to realize through the disposal of assets. The liquidation values of the Company’s real estate properties are presented on a net realizable value basis. Liabilities are carried at their contractual amounts due or estimated settlement amounts.
The Company accrues costs and revenues that it expects to incur and earn as it carries out its liquidation activities through the end of the projected liquidation period to the extent it has a reasonable basis for estimation. Estimated costs expected to be incurred through the end of the liquidation period include budgeted property expenses and corporate overhead, costs to dispose of its real estate property, costs associated with satisfying known and contingent liabilities and other costs associated with the winding down and dissolution of the Company. Revenues are based on in place leases. These amounts are classified as a liability for estimated costs in excess of estimated receipts during liquidation on the consolidated statement of net assets. Actual costs and income may differ from amounts reflected in the financial statements because of the inherent uncertainty in estimating future events. These differences may be material. See Note 2, “Plan of Sale” and Note 4, “Liabilities for Estimated Costs in Excess of Estimated Receipts During Liquidation” for further discussion.
Actual costs incurred but unpaid prior to the Company’s adoption of the liquidation basis of accounting on November 1, 2024, are included in accounts payable and accrued expenses and distributions payable on the consolidated statement of net assets. All our liabilities under either the going concern basis of accounting or the liquidation basis of accounting are derecognized when we pay the obligation or when we are legally released from being the primary obligor under the liability.
Net assets in liquidation represents the remaining estimated liquidation value available to shareholders upon liquidation. Due to the uncertainty in the estimated cash flows from operations and the time required to complete the Plan of Sale, actual liquidation costs and sale proceeds may differ materially from the amounts estimated.
As a result of the change to the liquidation basis of accounting, the Company no longer presents a consolidated balance sheet, a consolidated statement of operations, a consolidated statement of equity or a consolidated statement of cash flows subsequent to October 31, 2024. These statements are only presented for prior year periods. The consolidated financial statements include our investments in 100% owned subsidiaries and majority owned subsidiaries that are controlled by us. References to we, us, our and the Company, refer to Equity Commonwealth and its consolidated subsidiaries, unless the context indicates otherwise. All intercompany transactions and balances have been eliminated.
Dollar amounts presented may be approximate. Share amounts are presented in whole numbers, except where noted.
Use of Estimates
Use of Estimates    
Preparation of these financial statements in conformity with GAAP requires us to make estimates and assumptions that may affect the amounts reported in these financial statements and related notes. The Company is required to estimate all costs and revenue it expects to incur and earn through the end of liquidation including the estimated amount of cash it expects to collect on disposal of its assets and the estimated costs to dispose of its assets. All of the estimates and evaluations are susceptible to change and actual results could differ from these estimates.
Real Estate Properties
Real Estate Properties
Liquidation Basis of Accounting
As of November 1, 2024, the Company’s real estate was adjusted to its estimated net realizable value, or liquidation value, to reflect the change to the liquidation basis of accounting. The liquidation value represents the estimated amount of cash or other consideration that the Company expected to realize through the disposal of its assets. The Company estimated the liquidation value of its real estate based on a contractual purchase price for the property. The liquidation value of the Company’s real estate is presented on an undiscounted basis and real estate is no longer depreciated. Subsequent to November 1, 2024, all changes in the estimated liquidation value of the real estate is reflected as a change to the Company’s net assets in liquidation. Costs to sell the property such as credits for capital costs, contractual lease obligations and rent abatements are included in Liabilities for estimated costs in excess of estimated receipts during liquidation.
Going Concern Basis    
We record real estate properties at cost. We depreciate real estate investments on a straight-line basis over estimated useful lives of up to 40 years for buildings and improvements, and up to 12 years for personal property.
Each time we enter into a new lease, or materially modify an existing lease, we evaluate its classification as either a finance or operating lease. The classification of a lease as finance or operating affects the carrying value of a property, as well as our recognition of rental payments as revenue. These evaluations require us to make estimates of, among other things, the remaining useful life and fair market value of a leased property, appropriate discount rates and future cash flows.
We allocate the consideration paid for our properties among land, buildings and improvements and, for properties that qualify as acquired businesses under the Business Combinations Topic of the FASB Accounting Standards Codification, or ASC, to identified intangible assets and liabilities, consisting of the value of above market and below market leases, the value of acquired in place leases and the value of tenant relationships. Purchase price allocations and the determination of useful lives are based on our estimates and, under some circumstances, studies from independent real estate appraisal firms to provide market information and evaluations that are relevant to our purchase price allocations and determinations of useful lives; however, we are ultimately responsible for the purchase price allocations and determination of useful lives.
We allocate the consideration to land, buildings and improvements based on a determination of the fair values of these assets assuming the property is vacant. We determine the fair value of a property using methods that we believe are similar to those used by independent appraisers. Purchase price allocations for above market and below market leases are based on the estimated present value (using an interest rate which reflects our assessment of the risks associated with the leases acquired) of the difference between (1) the contractual amounts to be paid pursuant to the acquired in place leases and (2) our estimate of fair market lease rates for the corresponding leases, measured over a period equal to the remaining non-cancelable terms of the respective leases. Purchase price allocations to acquired in place leases and tenant relationships are determined as the excess of (1) the purchase price paid for a property after adjusting existing in place leases to estimated market rental rates over (2) the estimated fair value of the property as if vacant. We aggregate this value between acquired in place lease values and tenant relationships based on our evaluation of the specific characteristics of each tenant's lease; however, the value of tenant relationships has not been separated from acquired in place lease value for our properties because we believe such value and related amortization expense is immaterial for acquisitions reflected in our historical financial statements. We consider certain factors in performing these analyses including estimates of carrying costs during the expected lease up periods, including real estate taxes, insurance and other operating income and expenses and costs to execute similar leases in current market conditions, such as leasing commissions, legal and other related costs. If we believe the value of tenant relationships is material in the future, those amounts will be separately allocated and amortized over the estimated lives of the relationships. We recognize the excess, if any, of the consideration paid over amounts allocated to land, buildings and improvements and identified intangible assets and liabilities as goodwill and we recognize gains if amounts allocated exceed the consideration paid.
We amortize capitalized above market lease values as a reduction to rental income over the remaining terms of the respective leases. We amortize capitalized below market lease values as an increase to rental income over the remaining terms of the respective leases. We amortize the value of acquired in place leases exclusive of the value of above market and below market acquired in place leases to expense over the remaining terms of the respective leases. If a lease is terminated prior to its stated expiration, the unamortized lease intangibles relating to that lease is written off.
We review our properties for impairment quarterly, or whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. Impairment indicators may include our decision to dispose of an asset before the end of its estimated useful life, declining tenant occupancy, lack of progress releasing vacant space, tenant bankruptcies, low long-term prospects for improvement in property performance, weak or declining tenant profitability, and cash flow or liquidity. When indicators of potential impairment are present that suggest that the carrying amounts of real estate assets may not be recoverable, we assess the recoverability of these assets by determining whether the respective carrying values will be recovered through the estimated undiscounted future operating cash flows expected from the use of the assets and their eventual disposition. The determination of undiscounted cash flow includes consideration of many factors including income to be earned from the investment over our anticipated hold period, holding costs (exclusive of interest), estimated selling prices, and prevailing economic and market conditions. In the event that such expected undiscounted future cash flows do not exceed the carrying values, we estimate the fair value of the assets and record an impairment charge equal to the amount by which the carrying value exceeds the estimated fair value. Estimated fair values are calculated based on the following information, (i) recent third party estimates of market value, (ii) market prices for comparable properties, or (iii) the present value of future cash flows. During the ten months ended October 31, 2024, we recorded a loss on asset impairment of $49.3 million. During the years ended December 31, 2023 and 2022 we did not record any loss on asset impairment.
When we classify properties as held for sale, we discontinue the recording of depreciation expense and estimate their fair value less costs to sell. If we determine that the carrying value for these properties exceed their estimated fair value less costs to sell, we record a loss on asset impairment. As of December 31, 2023, we did not have any properties classified as held for sale.
Certain of our formerly owned real estate assets contained hazardous substances, including asbestos. We believe any asbestos in our former buildings is contained in accordance with current regulations. If the asbestos is removed or these properties are renovated or demolished, certain environmental regulations govern the manner in which the asbestos must be handled and removed. We do not believe that there are other environmental conditions or issues at any of our former properties that have had or will have a material adverse effect on us. However, no assurances can be given that we will not be required to incur costs in the future in connection with the remediation of contamination or compliance with environmental, health and safety laws that will have a material adverse effect on our business or financial condition.

Cash and Cash Equivalents    
Our cash and cash equivalents consist of cash maintained in time deposits, depository accounts and money market accounts.  We regularly monitor the credit ratings of the financial institutions holding our deposits to minimize our exposure to credit risk.  Throughout the year, we have cash balances in excess of federally insured limits deposited with various financial institutions. We do not believe we are exposed to any significant credit risk on cash and cash equivalents.
Other Assets, Net
Other Assets, Net
Going Concern Basis
Other assets consist principally of deferred leasing costs, capitalized lease incentives and prepaid property operating expenses. Deferred leasing costs are amortized on a straight-line basis over the terms of the respective leases. Capitalized lease incentives are amortized on a straight-line basis against rental income over the terms of the respective leases.
Accrued Liquidation Costs
Accrued Liquidation Costs
Liquidation Basis of Accounting
In accordance with the liquidation basis of accounting, the Company has recorded certain estimated liquidation costs to the extent it has a reasonable basis for estimation. These consist of compensation expense, legal fees, accounting fees, other professional service fees and other dissolution costs. These amounts are included in Liabilities for estimated costs in excess of estimated receipts during liquidation on the consolidated statement of net assets. See Note 4.
Revenue Recognition
Revenue Recognition
Liquidation Basis of Accounting
Under the liquidation basis of accounting, the Company has accrued all income that it expects to earn through the completion of its liquidation to the extent it has a reasonable basis for estimation. Revenue from tenants is estimated based on the contractual in place leases through the anticipated disposition date of the property. These amounts are presented net of
estimated expenses and other liquidation costs and are classified in liabilities for estimated costs in excess of estimated receipts during liquidation on the consolidated statement of net assets.
Going Concern Basis    
Rental revenue from operating leases, which includes rent concessions (including free rent and other lease incentives) and scheduled increases in rental rates during the lease term, represents the lease component and is recognized on a straight-line basis over the life of the lease agreements. We defer the recognition of contingent rental income, such as percentage rents, until the specific targets that trigger the contingent rental income are achieved. Rental revenue also includes non-lease components such as property level operating expenses reimbursed by our tenants and other incidental revenues, which are recorded as expenses are incurred. We concluded that the timing and pattern of transfer for non-lease components and the associated lease component are the same. We determined that the predominant component was the lease component and we have elected to account for and present the lease component and non-lease component of our leases as a single component in Rental revenue in our consolidated statements of operations in accordance with FASB Topic 842.
Lessee Lease Classification
Lessee Lease Classification
Going Concern Basis
We classify leases as either finance or operating in accordance with FASB Topic 842, Leases. This classification determines whether the related expense is recognized based on an effective interest method for finance leases or on a straight-line basis over its life for operating leases. Additionally, lessees are required to record a right-of-use asset and lease liability for all leases with a term greater than 12 months. We have made an accounting policy election as permitted under ASC 842 to forgo recognition of a right-of-use asset and lease liability for short-term leases of less than 12 months.
Earnings Per Common Share
Earnings Per Common Share    
Going Concern Basis
Earnings per common share, or EPS, is computed using the weighted average number of common shares outstanding during the period. Diluted EPS reflects the potential dilution that could occur if our series D convertible preferred shares, our restricted share units, or RSUs, or beneficial interests in the Operating Trust, or LTIP Units, were converted into our common shares, which could result in a lower EPS amount.
Reclassifications
Reclassifications    
Reclassifications have been made to the prior years' financial statements and notes to conform to the current year's presentation.
Legal Matters
Legal Matters
We are or may become a party to various legal proceedings. We are not currently involved in any litigation nor, to our knowledge, is any litigation threatened against us where the outcome would, in our judgment based on information currently available to us, have a material adverse effect on the Company.
Income Taxes
Income Taxes    
We are a REIT under the Internal Revenue Code of 1986, as amended, and are generally not subject to federal and state income taxes provided we distribute our taxable income to our shareholders and meet other requirements for qualifying as a REIT. We are also subject to certain state and local taxes without regard to our REIT status.
Going Concern Basis
The Income Taxes Topic of the FASB ASC prescribes how we should recognize, measure and present in our financial statements uncertain tax positions that have been taken or are expected to be taken in a tax return. Deferred tax assets are recognized to the extent that it is “more likely than not” that a particular tax position will be sustained upon examination or audit. To the extent the “more likely than not” standard has been satisfied, the benefit associated with a tax position is measured as the largest amount that has a greater than 50% likelihood of being realized upon settlement. We classify interest and penalties related to uncertain tax positions, if any, in our financial statements as a component of general and administrative expense.
New Accounting Pronouncements
New Accounting Pronouncements
In November 2023, the FASB issued Accounting Standards Update, or ASU, 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which improves the disclosures about a public entity's reportable segments and addresses requests from investors for additional, more detailed information about a reportable segment's expenses. This update is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. We adopted ASU 2023-07 on January 1, 2024, and the adoption did not have a material impact on our consolidated financial statements.
In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which enhances the transparency and decision usefulness of income tax disclosures. This update is effective for annual periods beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. We do not expect the adoption of ASU 2023-09 to have a material impact on our consolidated financial statements.
Fair Value
Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. A three-level valuation hierarchy exists for disclosures of fair value measurements based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. A financial instrument's categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The three levels are defined below:
Level 1 - Quoted prices in active markets for identical assets or liabilities.
Level 2 - Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
