Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization Peakstone Realty Trust (formerly known as Griffin Realty Trust, Griffin Realty Trust, Inc. and Griffin Capital Essential Asset REIT, Inc.) (“PKST” or the “Company”) is an internally managed, publicly registered real estate investment trust (“REIT”) that owns and operates a high-quality, newer-vintage portfolio of predominantly single-tenant industrial and office properties. The Company’s fiscal year-end is December 31. On December 14, 2018, the Company, Griffin Capital Essential Asset Operating Partnership II, L.P. (the “GCEAR II Operating Partnership”), the Company’s wholly-owned subsidiary Globe Merger Sub, LLC (“EA Merger Sub”), the entity formerly known as Griffin Capital Essential Asset REIT, Inc. (“our Predecessor”), and PKST OP, L.P. (formerly known as GRT OP, L.P. and Griffin Capital Essential Asset Operating Partnership, L.P.) (the “Operating Partnership”) entered into an Agreement and Plan of Merger (the “EA Merger Agreement”). On April 30, 2019, pursuant to the EA Merger Agreement, (i) our Predecessor merged with and into EA Merger Sub, with EA Merger Sub surviving as the Company’s direct, wholly-owned subsidiary (the “EA Company Merger”) and (ii) the GCEAR II Operating Partnership merged with and into the Operating Partnership (the “EA Partnership Merger” and, together with the EA Company Merger, the “Predecessor Mergers”), with the Operating Partnership surviving the EA Partnership Merger. In addition, on April 30, 2019, following the Predecessor Mergers, EA Merger Sub merged into the Company. On March 1, 2021, the Company completed its acquisition of Cole Office & Industrial REIT (CCIT II), Inc. (“CCIT II”) for approximately $1.3 billion, including transaction costs, in a stock-for-stock transaction (the “CCIT II Merger”). At the effective time of the CCIT II Merger, each issued and outstanding share of CCIT II Class A common shares and each issued and outstanding share of CCIT II Class T common shares were converted into the right to receive 0.155 Class E common shares. On July 1, 2021, the Company changed its name from Griffin Capital Essential Asset REIT, Inc. to Griffin Realty Trust, Inc. and the Operating Partnership changed its name from Griffin Capital Essential Asset Operating Partnership, L.P. to GRT OP, L.P. On November 10, 2022, the Company completed an internal restructuring pursuant to which the Operating Partnership became wholly owned by an operating company, GRT OP LLC (the “Operating Company”). On February 23, 2023, the Company completed an additional restructuring to restore the Company’s operating structure to its condition prior to the internal restructuring. The Operating Partnership owns, directly and indirectly, all of the properties that the Company has acquired. As of December 31, 2022, (i) the Company indirectly owned approximately 91.0% of the outstanding limited liability company units of the Operating Company ("OP Units"), (ii) the former sponsor and certain of its affiliates owned approximately 7.8% of the OP Units, including approximately 2.4 million OP Units owned by the Company’s current Executive Chairman and Chairman of the Company's Board of Trustees (the "Board"), Kevin A. Shields, a result of the contribution of five properties to the Company and the internalization of management of GRT in December 2018 (the "Self-Administration Transaction"), and (iii) the remaining approximately 1.2% of the OP Units are owned by unaffiliated third parties. The Operating Partnership may conduct certain activities through one or more of the Company’s taxable REIT subsidiaries, which are wholly-owned subsidiaries of the Operating Partnership. As of December 31, 2022, the Company ha d issued 31,904,106 common shares (approximately $2.8 billion) of common shares since November 9, 2009 in various private offerings, public offerings, distribution reinvestment plan ("DRP") offerings and mergers (includes our Predecessor’s offerings and our Predecessor’s merger with Signature Office REIT, Inc. and the CCIT II Merger). There were 35,999,898 common shares outstanding as of December 31, 2022, including shares issued pursuant to the DRP, less shares redeemed pursuant to the share redemption program ("SRP") and a self-tender offer. As of December 31, 2022 and 2021, the Company had issued approximately $341.1 million in shares pursuant to the DRP. On March 10, 2023, the Company completed a one-for-nine reverse share split with respect to each class of its common shares, converting every nine shares of the Company’s issued and outstanding common shares of each class into one share of such class, with no changes to the $0.001 par value per share. The reverse share split did not affect the number of the Company’s authorized common shares. The Company has retrospectively adjusted, for all periods presented, all share and per share amounts to reflect the impact of the reverse share split. Also on March 10, 2023, the Company changed its name from Griffin Realty Trust to Peakstone Realty Trust and the Operating Partnership changed its name from GRT OP, L.P. to PKST OP, L.P.

Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies The accompanying cons olidated financial statements of the Company are prepared by management on the accrual basis of accounting and in accordance with generally accepted accounting principles in the United States (“GAAP”) as contained in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”), and in conjunction with rules and regulations of the SEC. The consolidated financial statements include accounts and related adjustments, which are, in the opinion of management, of a normal recurring nature and necessary for a fair presentation of the Company's financial position, results of operations and cash flows for each of the three years in the period ended December 31, 2022, 2021, and 2020. The consolidated financial statements of the Company include all accounts of the Company and its subsidiaries, including the Operating Partnership. Intercompany transactions are not shown on the consolidated statements. However, each property owning entity is a wholly-owned subsidiary which is a special purpose entity ("SPE"), whose assets and credit are not available to satisfy the debts or obligations of any other entity, except to the extent required with respect to any co-borrower or guarantor under the same credit facility. Principles of Consolidation The Company's financial statements, and the financial statements of the Operating Partnership, including its wholly-owned subsidiaries, are consolidated in the accompanying consolidated financial statements. The portion of these entities not wholly-owned by the Company is presented as noncontrolling interests. All significant intercompany accounts and transactions have been eliminated in consolidation. Consolidation Considerations Current accounting guidance provides a framework for identifying a variable interest entity (“VIE”) and determining when a company should include the assets, liabilities, noncontrolling interests, and results of activities of a VIE in its consolidated financial statements. In general, a VIE is an entity or other legal structure used to conduct activities or hold assets that either (1) has an insufficient amount of equity to carry out its principal activities without additional subordinated financial support, (2) has a group of equity owners that are unable to make significant decisions about its activities, or (3) has a group of equity owners that do not have the obligation to absorb losses or the right to receive returns generated by its operations. Generally, a VIE should be consolidated if a party with an ownership, contractual, or other financial interest in the VIE (a variable interest holder) has the power to direct the VIE’s most significant activities and the obligation to absorb losses or right to receive benefits of the VIE that could be significant to the VIE. A variable interest holder that consolidates the VIE is called the primary beneficiary. Upon consolidation, the primary beneficiary generally must initially record all of the VIE’s assets, liabilities, and noncontrolling interests at fair value and subsequently account for the VIE as if it were consolidated based on majority voting interest. See Note 4, Investments in Unconsolidated Entities, for more detail . The Company has determined that the Operating Partnership is a variable interest entity because the holders of limited partnership interests do not have substantive kick-out rights or participation rights. Furthermore, the Company is the primary beneficiary of the Operating Partnership because the Company has the obligation to absorb losses and the right to receive benefits from the Operating Partnership and the exclusive power to direct the activities of the Operating Partnership. As of December 31, 2022 and 2021, the assets and liabilities of the Company and the Operating Partnership are substantially the same, as the Company does not have any significant assets other than its investment in the Operating Partnership. Cash and Cash Equivalents The Company considers all short-term, highly liquid investments that are readily convertible to cash with a maturity of three months or less at the time of purchase to be cash equivalents. Cash and cash equivalents may include cash and short-term investments. Short-term investments are stated at cost, which approximates fair value. There were no cash equivalents, nor were there restrictions on the use of the Company’s cash balance as of December 31, 2022 and 2021. The Company maintains its cash accounts with major financial institutions. The cash balances consist of business checking accounts. These accounts are insured by the Federal Deposit Insurance Corporation up to $250,000 at each institution. The Company has not experienced any losses with respect to cash balances in excess of government provided insurance. Management believes there was no significant concentration of credit risk with respect to these cash balances as of December 31, 2022. Restricted Cash In conjunction with acquisitions of certain assets, as required by certain lease provisions or certain lenders in conjunction with an acquisition or debt financing, or credits received by the seller of certain assets, the Company assumed or funded reserves for specific property improvements and deferred maintenance, re-leasing costs, and taxes and insurance, which are included on the consolidated balance sheets as restricted cash. Real Estate Purchase Price Allocation The Company applies the provisions in ASC 805-10, Business Combinations ( " ASC 805-10"), to account for the acquisition of real estate, or real estate related assets, in which a lease, or other contract, is in place representing an active revenue stream, as an asset acquisition (or when applicable, a business combination). In accordance with the provisions of ASC 805-10 (on an asset acquisition), the Company recognizes the assets acquired, the liabilities assumed and any noncontrolling interest in the acquired entity at their relative fair values. The accounting provisions have also established that transaction costs associated with an asset acquisition are capitalized. Acquired in-place leases are valued as above-market or below-market as of the date of acquisition. The valuation is measured based on the present value (using an interest rate, which reflects the risks associated with the leases acquired) of the difference between (a) the contractual amounts to be paid pursuant to the in-place leases and (b) management’s estimate of fair market lease rates for the corresponding in-place leases over a period equal to the remaining non-cancelable term of the lease for above-market leases, taking into consideration below-market extension options for below-market leases. In addition, renewal options are considered and will be included in the valuation of in-place leases if (1) it is likely that the tenant will exercise the option, and (2) the renewal rent is considered to be sufficiently below a fair market rental rate at the time of renewal. The above-market and below-market lease values are capitalized as intangible lease assets or liabilities and amortized as an adjustment to rental income over the remaining terms of the respective leases. The aggregate relative fair value of in-place leases includes direct costs associated with obtaining a new tenant, opportunity costs associated with lost rentals, which are avoided by acquiring an in-place lease, and tenant relationships. Direct costs associated with obtaining a new tenant include commissions, tenant improvements, and other direct costs, and are estimated using methods similar to those used in independent appraisals and management’s consideration of current market costs to execute a similar lease. These direct costs are considered intangible lease assets and are included with real estate assets on the consolidated balance sheets. The intangible lease assets are amortized to expense over the remaining terms of the respective leases. The value of opportunity costs is calculated using the contractual amounts to be paid, including real estate taxes, insurance, and other operating expenses, pursuant to the in-place leases over a market lease-up period for a similar lease. Customer relationships are valued based on management’s evaluation of certain characteristics of each tenant’s lease and the Company’s overall relationship with that respective tenant. Characteristics management will consider in allocating these values include the nature and extent of the Company’s existing business relationships with tenants, growth prospects for developing new business with the tenant, the tenant’s credit quality and expectations of lease renewals (including those existing under the terms of the lease agreement), among other factors. These intangibles will be included in intangible lease assets on the consolidated balance sheets and are amortized to expense over the remaining term of the respective leases. The determination of the relative fair values of the assets and liabilities acquired requires the use of significant assumptions about current market rental rates, rental growth rates, discount rates and other variables. Depreciation and Amortization The purchase price of real estate acquired and costs related to development, construction, and property improvements are capitalized. Repairs and maintenance costs include all costs that do not extend the useful life of the real estate asset and are expensed as incurred. The Company considers the period of future benefit of an asset to determine the appropriate useful life. The Company anticipates the estimated useful lives of its assets by class to be generally as follows: Buildings 25-40 years Building Improvements 5-20 years Land Improvements 15-25 years Tenant Improvements Shorter of estimated useful life or remaining contractual lease term Tenant Origination and Absorption Cost Remaining contractual lease term In-place Lease Valuation Remaining contractual lease term with consideration as to below-market extension options for below-market leases If a lease is terminated or amended prior to its scheduled expiration, the Company will accelerate/extend the remaining useful life of the unamortized lease-related costs. Impairment of Real Estate and Related Intangible Assets In accordance with the provisions of the Impairment or Disposal of Long-Lived Assets Subsections of ASC 360, the Company assesses the carrying values of our respective long-lived assets whenever events or changes in circumstances indicate that the carrying amounts of these assets may not be fully recoverable. Recoverability of real estate assets is measured by comparison of the carrying amount of the asset to the estimated future undiscounted cash flows. To review real estate assets for recoverability, the Company considers current market conditions as well as the Company's intent with respect to holding or disposing of the asset. The intent with regard to the underlying assets might change as market conditions and other factors change. Fair value is determined through various valuation techniques, including discounted cash flow models, applying a capitalization rate to estimated net operating income of a property, and quoted market values and third party appraisals, where considered necessary. The use of projected future cash flows is based on assumptions that are consistent with estimates of future expectations and the strategic plan used to manage the Company's underlying business. If the Company’s analysis indicates that the carrying value of the real estate asset is not recoverable on an undiscounted cash flow basis, the Company will recognize an impairment charge for the amount by which the carrying value exceeds the current estimated fair value of the real estate property. Projections of expected future undiscounted cash flows require management to estimate future market rental income amounts subsequent to the expiration of current lease agreements, property operating expenses, discount and capitalization rates, the number of months it takes to re-lease the property, and the number of years the property is held for investment. Revenue Recognition Leases associated with the acquisition and contribution of certain real estate assets have net minimum rent payment increases during the term of the lease and are recorded to rental revenue on a straight-line basis, commencing as of the contribution or acquisition date. If a lease provides for contingent rental income, the Company will defer the recognition of contingent rental income, such as percentage rents, until the specific target that triggers the contingent rental income is achieved. Tenant reimbursement revenue, which is comprised of additional amounts collected from tenants for the recovery of certain operating expenses, including repair and maintenance, property taxes (excluding taxes paid by a lessee directly to a third party on behalf of the lessor) and insurance, and capital expenditures, to the extent allowed pursuant to the lease (collectively, "Recoverable Expenses"), is recognized as revenue when the additional rent is due. Recoverable Expenses to be reimbursed by a tenant are determined based on the Company's estimate of the property's operating expenses for the year, pro-rated based on leased square footage of the property, and are collected in equal installments as additional rent from the tenant, pursuant to the terms of the lease. At the end of each quarter, the Company reconciles the amount of additional rent paid by the tenant during the quarter to the actual amount of the Recoverable Expenses incurred by the Company for the same period. The difference, if any, is either charged or credited to the tenant pursuant to the provisions of the lease. In certain instances, the lease may restrict the amount the Company can recover from the tenant, such as a cap on certain or all property operating expenses. In a situation in which a lease associated with a significant tenant has been, or is expected to be, terminated early, or extended, the Company evaluates the remaining useful life of amortizable assets in the asset group related to the lease that will be terminated (i.e. above- and below-market lease intangibles, in-place lease value and deferred leasing costs). Based upon consideration of the facts and circumstances surrounding the termination or extension, the Company may write-off or accelerate the amortization associated with the asset group. Such amounts are included within rental and other income for above- and below-market lease intangibles and amortization for the remaining lease related asset groups in the consolidated statements of operations. Lease Accounting On January 1, 2019, the Company adopted ASC 842 using the modified retrospective approach and elected to apply the provisions as of the date of adoption on a prospective basis. Upon adoption of ASC 842, the Company elected the “package of practical expedients,” which allowed the Company to not reassess (a) whether expired or existing contracts as of January 1, 2019 are or contain leases, (b) the lease classification for any expired or existing leases as of January 1, 2019, and (c) the treatment of initial direct costs relating to any existing leases as of January 1, 2019. The package of practical expedients was made as a single election and was consistently applied to all leases that commenced before January 1, 2019. Lessor ASC 842 requires lessors to account for leases using an approach that is substantially equivalent to ASC 840 for sales-type leases, direct financing leases, and operating leases. As the Company elected the package of practical expedients, the Company's existing leases as of January 1, 2019 continue to be accounted for as operating leases. Upon adoption of ASC 842, the Company elected the practical expedient permitting lessors to elect by class of underlying asset to not separate nonlease components (for example, maintenance services, including common area maintenance) from associated lease components (the “non-separation practical expedient”) if both of the following criteria are met: (1) the timing and pattern of transfer of the lease and non-lease component(s) are the same and (2) the lease component would be classified as an operating lease if it were accounted for separately. If both criteria are met, the combined component is accounted for in accordance with ASC 842 if the lease component is the predominant component of the combined component; otherwise, the combined component is accounted for in accordance with the revenue recognition standard. The Company assessed the criteria above with respect to the Company's operating leases and determined that they qualify for the non-separation practical expedient. As a result, the Company accounted for and presented all rental income earned pursuant to operating leases, including property expense recovery, as a single line item, “Rental income,” in the consolidated statement of operations for all periods presented. Prior to the adoption of ASC 842, the Company presented rental income, property expense recovery and other income related to leases separately in the Company's consolidated statements of operations. Under ASC 842, lessors are required to record revenues and expenses on a gross basis for lessor costs (which include real estate taxes) when these costs are reimbursed by a lessee. Conversely, lessors are required to record revenues and expenses on a net basis for lessor costs when they are paid by a lessee directly to a third party on behalf of the lessor. Prior to the adoption of ASC 842, the Company recorded revenues and expenses on a gross basis for real estate taxes whether they were reimbursed to the Company by a tenant or paid directly by a tenant to the taxing authorities on the Company's behalf. Effective January 1, 2019, the Company is recording these costs in accordance with ASC 842. Lessee ASC 842 requires lessees to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right-of-use asset (“ROU asset”), which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. ASC 842 also requires lessees to classify leases as either finance or operating leases based on whether or not the lease is effectively a financed purchase of the leased asset by the lessee. This classification is used to evaluate whether the lease expense should be recognized based on an effective interest method or on a straight-line basis over the term of the lease. On January 1, 2019, the Company was the lessee on two ground leases, which were classified as operating leases under ASC 840. As the Company elected the packages of practical expedients, the Company is not required to reassess the classification of these existing leases and, as such, these leases continue to be accounted for as operating leases. On January 1, 2019, the Company recognized ROU assets and lease liabilities for these leases on the Company's consolidated balance sheets, and on a go-forward basis, lease expense will be recognized on a straight-line basis over the remaining term of the lease. On January 1, 2019, the Company recorded a ROU asset of $25.5 million and a corresponding liability of approximately $27.6 million relating to the Company's existing ground lease arrangements. These operating leases were recognized based on the present value of the future minimum lease payments over the lease term. As these leases do not provide an implicit rate, the Company used its incremental borrowing rate based on the information available in determining the present value of future payments. The discount rate used to determine the present value of these operating leases’ future payments was 5.36%. There was no impact to beginning equity as a result of the adoption related to the lessee accounting as the difference between the asset and liability is attributed to derecognition of pre-existing straight-line rent balances. Upon adoption of ASC 842, the Company also elected the practical expedient to not separate non-lease components, such as common area maintenance, from associated lease components for the Company's ground and office space leases. Derivative Instruments and Hedging Activities ASC 815, Derivatives and Hedging ("ASC 815") provides the disclosure requirements for derivatives and hedging activities with the intent to provide users of financial statements with an enhanced understanding of: (a) how and why an entity uses derivative instruments, (b) how the entity accounts for derivative instruments and related hedged items, and (c) how derivative instruments and related hedged items affect an entity’s financial position, financial performance, and cash flows. Further, ASC 815 requires qualitative disclosures regarding the Company’s objectives and strategies for using derivatives, as well as quantitative disclosures about the fair value of gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative instruments. As required by ASC 815, the Company recorded all derivatives on the consolidated balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, and whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain risks, even though hedge accounting does not apply or the Company elects not to apply hedge accounting. See Note 6, Interest Rate Contracts , for more detail. Change in Consolidated Financial Statements Presentation Certain amounts in the prior period consolidated financial statements have been reclassified to conform to the current period presentation. Interest rate swap assets have been reclassified from other assets to interest rate swap assets on the balance sheet for all periods presented. Income Taxes The Company has elected to be taxed as a REIT under the Internal Revenue Code ("Code"). To qualify as a REIT, the Company must meet certain organizational and operational requirements. The Company intends to adhere to these requirements and maintain its REIT status for the current year and subsequent years. As a REIT, the Company generally will not be subject to federal income taxes on taxable income that is distributed to shareholders. However, the Company may be subject to certain state and local taxes on its income and property, and federal income and excise taxes on its undistributed taxable income, if any. If the Company fails to qualify as a REIT in any taxable year, the Company will then be subject to federal income taxes on the taxable income at regular corporate rates and will not be permitted to qualify for treatment as a REIT for federal income tax purposes for four years following the year during which qualification is lost unless the Internal Revenue Service ("IRS") grants the Company relief under certain statutory provisions. Such an event could materially adversely affect net income and net cash available for distribution to shareholders. As of December 31, 2022, the Company satisfied the REIT requirements and distributed all of its taxable income. Pursuant to the Code, the Company has elected to treat its corporate subsidiary as a taxable REIT subsidiary (“TRS”). In general, the TRS may perform non-customary services for the Company’s tenants and may engage in any real estate or non-real estate-related business. The TRS will be subject to corporate federal and state income tax. Goodwill Goodwill arises from business combinations and represents the excess of the cost of an acquired entity over the net fair value amounts that were assigned to the identifiable assets acquired and the liabilities assumed. The Company recorded goodwill as a result of the transaction that resulted in the internalization of GRT management in December 2018 (“Self-Administration Transaction”). The Company’s goodwill has an indeterminate life and is not amortized, but is tested for impairment on an annual basis for each reporting unit, or more frequently if events or changes in circumstances indicate that the asset is more likely than not impaired. On October 1st of each period, the Company performs a qualitative analysis to determine whether an impairment of goodwill exists prior to quantitatively determining the fair value of the reporting units in step one of the impairment test. If a quantitative assessment is deemed necessary, and to the extent the carrying amount of the reporting unit’s allocated goodwill exceeds the unit’s fair value, the Company recognizes an impairment of goodwill for the excess up to the amount of goodwill of that reporting unit. Due to the Company’s operating segment realignment in the fourth quarter of 2022, the composition of its reporting units for the evaluation of goodwill impairment was changed and resulted in a quantitative assessment of goodwill impairment. Prior to the change, the Company tested the goodwill for impairment at the previous single reporting unit, which did not result in any impairment charge. Goodwill is now allocated across all three of the Company’s Office, Industrial, and Other reporting units on a relative fair value basis, which is determined as the fair value of assets less liabilities for each reporting unit. Given this method, the fair value of real estate assets and mortgage loans included within each reporting unit were the significant components in determining relative fair value. The Company estimated the fair value of real estate assets using a discounted cash flow model, including forecasted future cash flows based on significant assumptions such as market rent, and the determination of appropriate discount and terminal capitalization rates. The Company estimated the fair value of the mortgage loans in each reporting unit by discounting each loan’s principal balance over the remaining term of the mortgage using current borrowing rates available to the Company for debt instruments with similar terms and maturities. The Company determined that the amounts within the consolidated financial statements for the remaining assets and liabilities approximated fair value. For any corporate related amounts that were not specifically identifiable to any reporting unit, the Company allocated those amounts on a relative fair value basis using the specifically identified assets and liabilities. As a result of the quantitative assessment as of December 31, 2022, the Company concluded that it was more likely than not that the fair value of the Office reporting unit was less than the carrying amount, especially given the general decline in overall demand for office assets. Thus, the Company recorded a $135.3 million goodwill impairment, which represents the entire amount of goodwill allocated to the Office segment. See Note 8, Fair Value Measurements , for details regarding the inputs used in determining the impairment of goodwill. See Note 14, Segment Reporting , for allocation of goodwill for each of the Company’s segments. Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the unaudited consolidated financial statements and accompanying notes. Actual results could materially differ from those estimates. Per Share Data The Company reports earnings per share for the period as (1) basic earnings per share computed by dividing net income (loss) attributable to common shareholders by the weighted average number of common shares outstanding during the period, and (2) diluted earnings per share computed by dividing net income (loss) attributable to common shareholders by the weighted average number of common shares outstanding, including common shares equivalents. Unvested RSUs that contain non-forfeitable rights to dividends are participating securities and are included in the computation of earnings per share pursuant to the two-class method. The effect of including unvested restricted shares using the treasury stock method was excluded from our calculation of weighted average common shares outstanding – diluted, as the inclusion would have been anti-dilutive for the years ended December 31, 2022, 2021 and 2020. Total excluded shares were 212,152, 150,037, and 50,371 for the years ended December 31, 2022, 2021, and 2020, respectively. Segment Information In the fourth quarter of 2022, the Company evolved the management strategy of its real estate portfolio to focus on three different property types in order to maximize the value of the assets within each group. As a result, the Company changed to three reportable segments: Industrial, Office, and Other. The Industrial segment consists of high-quality, well-located industrial properties with modern specifications. The Office segment includes newer, high-quality, and business-essential office properties. The Other segment consists of vacant and non-core properties, together with other properties in the same cross-collateralized loan pools. This segment includes properties that are either non-stabilized, leased to tenants with shorter lease terms or are being evaluated for repositioning, re-leasing or potential sale. The Company recast its segment results for all prior periods presented to show the three reportable segments. See Note 14, Segment Reporting , for details regarding each of the Company’s segments. Unaudited Data Any references to the number of buildings, square footage, number of leases, occupancy, and any amounts derived from these values in the notes to the consolidated financial statements are unaudited and outside the scope of the Company's independent registered public accounting firm's audit of its consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board ("PCAOB"). Recently Issued Accounting Pronouncements Changes to GAAP are established by the FASB in the form of ASUs to the FASB’s Accounting Standards Codification. The Company considers the applicability and impact of all ASUs. Other than the ASUs discussed below, the FASB has not recently issued any other ASUs that the Company expects to be applicable and have a material impact on the Company's financial statements. Adoption of New Accounting Pronouncements In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”). ASU 2020-04 provides temporary optional guidance that provides transition relief for reference rate reform, including optional expedients and exceptions for applying GAAP to contract modifications, hedging relationships and other transactions that reference LIBOR or a reference rate that is expected to be discontinued as a result of reference rate reform if certain criteria are met. ASU 2020-04 is effective upon issuance, and the provisions generally can be applied prospectively as of January 1, 2020 through December 31, 2023. During the first quarter of 2020, the Company elected to apply the hedge accounting expedients related to probability and the assessments of effectiveness for future LIBOR-indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. The Company has subsequently elected to apply additional expedients related to

Real Estate [Abstract]
Real Estate	Real Estate As of December 31, 2022, the Company’s real estate portfolio consisted of 81 properties in 24 states consisting substantially of office, industrial, and manufacturing facilities with a combined acquisition value of approximately $3.4 billion, including the allocation of the purchase price to above and below-market lease valuation. Depreciation expense for buildings and improvements for the years ended December 31, 2022, 2021, and 2020 was $113.2 million, $125.4 million, and $94.0 million, respectively.

Equity Method Investments and Joint Ventures [Abstract]
Investments in Unconsolidated Entities	Investments in Unconsolidated Entities Office Joint Venture The Company, through its subsidiary GRT VAO OP, LLC (“GRT VAO Sub”), owns indirectly an approximate 49% interest in the Office Portfolio, equal to approximately $178.6 million, through a joint venture (the “Office Joint Venture”). The Office Joint Venture is managed by RVMC Capital LLC, an affiliate of Workspace Property Trust (the “Managing Member”). The Managing Member of the Office Joint Venture has general authority to manage the operations of the Office Joint Venture. The Managing Member also has day-to-day management authority over the Office Joint Venture, subject to certain major decision rights held by another minority interest holder. The Managing Member may be removed from its management positions upon the occurrence of specified events. GRT VAO Sub has approval rights over certain major decisions regarding actions by the Office Joint Venture, including certain fundamental decisions that the Office Joint Venture may approve. GRT VAO Sub’s obligation is generally limited to its initial contribution. GRT VAO Sub is not obligated to make any additional capital contributions beyond its initial capital contribution. The Office Joint Venture, through various subsidiary borrowers, obtained acquisition financing for the Office Portfolio comprised of (a) a $736.0 million mortgage loan (the “Mortgage Loan”), and (b) a $194.8 million mezzanine loan (the “Mezzanine Loan”, and together with the Mortgage Loan, the “Office JV Loans”). The initial maturity date of the Office JV Loans is September 9, 2023, subject to two, one-year extension options. The interest rates during the initial term of the Mortgage Loan and the Mezzanine Loan are Term SOFR (1-month) (with a 3% interest rate cap on SOFR) + 3.635% (subject to a 0.25% increase during each extension term) and Term SOFR (1-month) with a 3% interest rate cap on SOFR + 6.574% (subject to a 0.25% increase during each extension term), respectively. The Office Joint Venture paid $6.7 million for the interest rate caps. The Office Joint Venture, through various subsidiary borrowers, also obtained acquisition financing for a companion sale of a majority interest in a five property portfolio, comprised of a $142.1 million mortgage loan, having an initial maturity date of January 6, 2024 (subject to two, one-year extension options), and an interest rate during the initial term of Term SOFR (1-month) with a 4% interest rate cap on SOFR + 4.25% (subject to a 0.25% increase during each extension term). The Company has not guaranteed any debt obligations and has not otherwise committed to providing financial support in respect of the debt. In addition, the Company does not anticipate receiving any near-term cash flow distributions. Considering the Company’s limited economic exposure to the Office Joint Venture, the Company excludes interests in the assets in the Office Joint Venture from operating data. In connection with the Office JV Loans, the Operating Partnership and GRT VAO Sub entered into a certain Put Agreement with JPMorgan Chase Bank, National Association (“JPM”), pursuant to which JPM had the right to put to Operating Partnership and GRT VAO Sub a portion of its interest in the Mezzanine Loan in the principal face amount of $39.3 million (the “Mezzanine Interest”). On September 29, 2022, JPM sold to GRT VAO Sub the Mezzanine Interest for approximately $34.4 million, which was initially included in the line item “Investments in unconsolidated entities” in the consolidated balance sheets. On December 23, 2022, we sold the Mezzanine Interest for $31.0 million. We recorded an estimated loss of approximately $3.6 million, which includes accrued interest and is presented in the "Net loss from investment in unconsolidated entities” in the consolidated statement of operations. The interests discussed above are deemed to be variable interests in variable interest entities ("VIE") and based on an evaluation of the variable interests against the criteria for consolidation, the Company determined that it is not the primary beneficiary of the investment, as the Company does not have power to direct the activities of the entities that most significantly affect their performance. As such, the interest in the VIE is recorded using the equity method of accounting in the accompanying consolidated financial statements. Under the equity method, the investments in the unconsolidated entities are stated at cost and adjusted for the Company’s share of net earnings or losses and reduced by distributions. Equity in earnings of real estate ventures is generally recognized based on the allocation of cash distributions upon liquidation of the investment at book value in accordance with the operating agreements. The Company records the net earnings or losses on investment on a one quarter lag. The Company's maximum exposure to losses associated with its unconsolidated investments is primarily limited to its carrying value in the investments. The table below summarizes the Company’s investment in the unconsolidated Office Joint Venture, which is included in the Company’s Office segment: Office Joint Venture Investment in Office Joint Venture Balance at December 31, 2021 $ — Contributions 218,746 Net loss (1) (10,979) Sale of Mezzanine Loan Interest (31,000) Other Comprehensive Income 1,880 Balance at December 31, 2022 $ 178,647 (1) The net loss includes $3.6 million of loss on the sale of the Mezzanine Loan.

The $200M 5-Year Term Loan was paid-off as noted below. The credit facility also provides the option, subject to obtaining additional commitments from lenders and certain other customary conditions, to increase the commitments under the Revolving Credit Facility, increase the existing term loans and/or incur new term loans by up to an additional $600 million in the aggregate. As of December 31, 2022, the remaining capacity under the Revolving Credit Facility was $202.9 million. The Second Amended and Restated Credit Agreement provides that the Operating Partnership must maintain a pool of unencumbered real properties (each a "Pool Property" and collectively the "Pool Properties") that meet certain requirements contained in the Second Amended and Restated Credit Agreement. The agreement sets forth certain covenants relating to the Pool Properties, including, without limitation, the following: • there must be no less than 15 Pool Properties at any time; • no greater than 15% of the aggregate pool value may be contributed by a single Pool Property or tenant; • no greater than 15% of the aggregate pool value may be contributed by Pool Properties subject to ground leases; • no greater than 20% of the aggregate pool value may be contributed by Pool Properties which are under development or assets under renovation; • the minimum aggregate leasing percentage of all Pool Properties must be no less than 90%; and • other limitations as determined by KeyBank upon further due diligence of the Pool Properties. Borrowing availability under the Second Amended and Restated Credit Agreement is limited to the lesser of the maximum amount of all loans outstanding that would result in (i) an unsecured leverage ratio of no greater than 60%, or (ii) an unsecured interest coverage ratio of no less than 2.00:1.00. Guarantors of the KeyBank Loans include the Company, each special purpose entity that owns a Pool Property, and each of the Operating Partnership's other subsidiaries which owns a direct or indirect equity interest in a SPE that owns a Pool Property. In addition to customary representations, warranties, covenants, and indemnities, the KeyBank Loans require the Operating Partnership to comply with the following at all times, which will be tested on a quarterly basis: • a maximum consolidated leverage ratio of 60%, or, the ratio may increase to 65% for up to four consecutive quarters after a material acquisition; • a minimum consolidated tangible net worth of 75% of the Company's consolidated tangible net worth at closing of the Revolving Credit Facility, or approximately $2.0 billion, plus 75% of net future equity issuances (including OP Units), minus 75% of the amount of any payments used to redeem the Company's shares or OP Units, minus any amounts paid for the redemption or retirement of or any accrued return on the preferred equity issued under the preferred equity investment made in our Predecessor in August 2018 by SHBNPP Global Professional Investment Type Private Real Estate Trust No. 13 (H), and minus 75% of the tangible net worth of certain distributions and/or dividends (defined as “Restricted Payments”) that are otherwise permitted by the Second Amended and Restated Credit Agreement; • upon consummation, if ever, of an initial public offering, a minimum consolidated tangible net worth of 75% of the Company's consolidated tangible net worth at the time of such initial public offering plus 75% of net future equity issuances (including OP Units) should the Company publicly list its shares; • a minimum consolidated fixed charge coverage ratio of not less than 1.50:1.00; • a maximum total secured debt ratio of not greater than 40%, which ratio will increase by five percentage points for four quarters after closing of a material acquisition that is financed with secured debt; • a minimum unsecured interest coverage ratio of 2.00:1.00; • a maximum total secured recourse debt ratio, excluding recourse obligations associated with interest rate hedges, of 10% of our total asset value; and • aggregate maximum unhedged variable rate debt of not greater than 30% of the Company's total asset value. Furthermore, the activities of the Operating Partnership, the Company, and the Company's subsidiaries must be focused principally on the ownership, development, operation and management of office, industrial, manufacturing, warehouse, distribution or educational properties (or mixed uses thereof) and businesses reasonably related or ancillary thereto. Third Amendment to Second Amended and Restated Credit Agreement On July 14, 2021, the Company, through the Operating Partnership, entered into the Third Amendment. The Third Amendment amended the Second Amended and Restated Credit Agreement to decrease the applicable interest rate margin for the $150M 7-Year Term Loan. After giving effect to the Third Amendment, the $150M 7-Year Term Loan accrues interest, at the Operating Partnership’s election, at a per annum rate equal to either (i) the LIBOR plus an applicable margin ranging from 1.25% to 2.15% or (ii) a base rate plus an applicable margin ranging from 0.25% to 1.15%, in each case such applicable margin to be based on the Company's consolidated leverage ratio. Prior to the Third Amendment, the applicable margin for LIBOR based loans was 1.65% to 2.50% and for base rate loans was 0.65% to 1.50%, in each case based on the Company's consolidated leverage ratio. All other terms of the Second Amended and Restated Credit Agreement were unchanged. No new term loan borrowings were incurred under the Third Amendment. The applicable rate for the $150M 7-Year Term Loan decreased 35 basis points from 1.75% to 1.40%. Fourth Amendment to the Second Amended and Restated Credit Agreement Pursuant to the Fourth Amendment, the Company amended the Company’s maturity extension option on the Revolving Credit Facility from a one-year extension option (to June 2023) to a series of three-month extension options (to September 28, 2022, December 28, 2022, March 28, 2023, and June 28, 2023, respectively). The exercise of each extension option requires the payment of a fee of 0.05% on the extended revolving loan commitments and is subject to certain other customary conditions. On May 24, 2022, the Company exercised the first three-month extension option on the Revolving Credit Facility, which extends the maturity date from June 28, 2022 to September 28, 2022. Upon the sale of the Office Portfolio and property in Phoenix, Arizona, the Company repaid approximately $373.5 million of the Revolving Credit Facility and paid off approximately $200.0 million of the 2023 Term Loan. See Note 3, Real Estate , for details of the sale of the Office Portfolio. Fifth Amendment to the Second Amended and Restated Credit Agreement Pursuant to the Fifth Amendment, the Company extended the maturity date on the Revolving Credit Facility from September 28, 2022 to September 30, 2023 and amended the maturity date extension options to a series of three three-month extensions (to December 30, 2023, March 30, 2024 and June 30, 2024, respectively). In addition, the contract interest rate was amended from LIBOR to Secured Overnight Financing Rate (“SOFR”) plus 0.10% per annum (collectively, the “Adjusted SOFR”). See Note 2, Basis of Presentation and Summary of Significant Accounting Policie s, for details on the impact of the Company’s hedge accounting. Based on the terms as of December 31, 2022, the interest rate for the credit facility varies based on the consolidated leverage ratio of the Operating Partnership, us, and our subsidiaries and ranges (a) in the case of the Revolving Credit Facility, from Adjusted SOFR plus 1.30% to Adjusted SOFR plus 2.20%, (b) in the case of each of the $400M 5-Year Term Loan, the $400M 5-Year Term Loan 2025, and the $150M 7-Year Term Loan, from Adjusted SOFR plus 1.25% to Adjusted SOFR plus 2.15%. If the Operating Partnership obtains an investment grade rating of its senior unsecured long term debt from Standard & Poor's Rating Services, Moody's Investors Service, Inc., or Fitch, Inc., the applicable SOFR margin and base rate margin will vary based on such rating and range (i) in the case of the Revolving Credit Facility, from Adjusted SOFR plus 0.825% to Adjusted SOFR plus 1.55%, (ii) in the case of each of the $400M 5-Year Term Loan, the $400M 5-Year Term Loan 2025, and the $150M 7-Year Term Loan, from Adjusted SOFR plus 0.90% to Adjusted SOFR plus 1.75%. As of December 31, 2022, the remaining undrawn capacity under the Revolving Credit Facility was $202.9 million. Sixth Amendment to the Second Amended and Restated Credit Agreement Pursuant to the Sixth Amendment, the Company amended the Second Amended and Restated Credit Agreement by, among other things, amending the covenant regarding Tangible Net Worth (as defined in the Second Amended and Restated Credit Agreement) such that the calculation thereof takes into account certain distributions and/or dividends (defined as “Restricted Payments”) that are otherwise permitted by Second Amended and Restated Credit Agreement. Midland Mortgage Loan and BOA Loan As a result of the sale of the Office Portfolio, the Company repaid approximately $95.7 million and $388.5 million of the Midland Mortgage Loan and BOA Loan, respectively, which included a prepayment premium of approximately $0.9 million for the Midland Mortgage Loan and $12.3 million for the BOA Loan. See Note 3, Real Estate, for details of the sale of the Office Portfolio. Debt Covenant Compliance Pursuant to the terms of the Company's mortgage loans and the KeyBank Loans, the Operating Partnership, in consolidation with the Company, is subject to certain loan compliance covenants. The Company was in compliance with all of its debt covenants as of December 31, 2022. The following summarizes the future scheduled principal repayments of all loans as of December 31, 2022 per the loan terms discussed above: As of December 31, 2022 2023 $ 43,101 2024 433,929 2025 519,901 2026 152,546 2027 2,675 Thereafter 337,651 Total principal 1,489,803 Unamortized debt premium/(discount) 240 Unamortized deferred loan costs (4,641) Total $ 1,485,402

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Interest Rate Contracts	Interest Rate Contracts Risk Management Objective of Using Derivatives The Company is exposed to certain risks arising from both 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 debt funding and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the payment of future known and uncertain cash amounts, the values of which are determined by expected cash payments principally related to borrowings and interest rates. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The Company does not use derivatives for trading or speculative purposes. Derivative Instruments The Company has entered into interest rate swap agreements to hedge the variable cash flows associated with certain existing or forecasted LIBOR based variable-rate debt, including the Company's KeyBank Loans. The change in the fair value of derivatives designated and qualifying as cash flow hedges is initially recorded in accumulated other comprehensive income ("AOCI") and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. Amounts reported in AOCI related to derivatives will be reclassified to interest expense as interest payments are made on the Company's variable-rate debt. The following table sets forth a summary of the interest rate swaps at December 31, 2022 and 2021: Fair Value (1) Current Notional Amounts December 31, December 31, Derivative Instrument Effective Date Maturity Date Interest Strike Rate 2022 2021 2022 2021 Assets/(Liabilities) Interest Rate Swap 3/10/2020 7/1/2025 0.83% $ 12,391 $ 1,648 $ 150,000 $ 150,000 Interest Rate Swap 3/10/2020 7/1/2025 0.84% 8,244 1,059 100,000 100,000 Interest Rate Swap 3/10/2020 7/1/2025 0.86% 6,145 749 75,000 75,000 Interest Rate Swap 7/1/2020 7/1/2025 2.82% 4,331 (7,342) 125,000 125,000 Interest Rate Swap 7/1/2020 7/1/2025 2.82% 3,444 (5,909) 100,000 100,000 Interest Rate Swap 7/1/2020 7/1/2025 2.83% 3,441 (5,899) 100,000 100,000 Interest Rate Swap 7/1/2020 7/1/2025 2.84% 3,408 (5,958) 100,000 100,000 Total $ 41,404 $ (21,652) $ 750,000 $ 750,000 (1) The Company records all derivative instruments on a gross basis in the consolidated balance sheets, and accordingly there are no offsetting amounts that net assets against liabilities. As of December 31, 2022, derivatives in a liability position are included in an asset or liability position are included in the line item "Other assets or Interest rate swap liability," respectively, in the consolidated balance sheets at fair value. The LIBO rate as of December 31, 2022 (effective date) was 4.12%. The following table sets forth the impact of the interest rate swaps on the consolidated statements of operations for the periods presented: Year Ended December 31, 2022 2021 2020 Interest Rate Swap in Cash Flow Hedging Relationship: Amount of (loss) gain recognized in AOCI on derivatives $ 61,126 $ (18,165) $ (38,319) Amount of (gain) loss reclassified from AOCI into earnings under “Interest expense” $ (2,056) $ (14,284) $ 8,165 Total interest expense presented in the consolidated statement of operations in which the effects of cash flow hedges are recorded $ 84,816 $ 85,087 $ 79,646 During the twelve months subsequent to December 31, 2022, the Company estimates that an additional $21.5 million of its expense will be recognized from AOCI into earnings. Certain agreements with the derivative counterparties contain a provision that if the Company defaults on any of its indebtedness, including a default where repayment of the indebtedness has not been accelerated by the lender within a specified time period, then the Company could also be declared in default on its derivative obligations.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company is required to disclose fair value information about all financial instruments, whether or not recognized in the consolidated balance sheets, for which it is practicable to estimate fair value. The Company measures and discloses the estimated fair value of financial assets and liabilities utilizing a fair value hierarchy that distinguishes between data obtained from sources independent of the reporting entity and the reporting entity’s own assumptions about market participant assumptions. This hierarchy consists of three broad levels, as follows: (i) quoted prices in active markets for identical assets or liabilities, (ii) "significant other observable inputs," and (iii) "significant unobservable inputs." "Significant other observable inputs" can include quoted prices for similar assets or liabilities in active markets, as well as inputs that are observable for the asset or liability, such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals. "Significant unobservable inputs" are typically based on an entity’s own assumptions, since there is little, if any, related market activity. In instances in which 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 of 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. There were no transfers between the levels in the fair value hierarchy during the years ended December 31, 2022 and 2021. The following table sets forth the assets and liabilities that the Company measures at fair value on a recurring basis by level within the fair value hierarchy as of December 31, 2022 and 2021: Assets/(Liabilities) Total Fair Value Quoted Prices in Active Markets for Identical Assets and Liabilities Significant Other Observable Inputs Significant Unobservable Inputs December 31, 2022 Interest Rate Swap Asset $ 41,404 $ — $ 41,404 $ — Mutual Funds Asset $ 6,191 $ 6,191 $ — $ — December 31, 2021 Interest Rate Swap Asset $ 3,456 $ — $ 3,456 $ — Interest Rate Swap Liability $ (25,108) $ — $ (25,108) $ — Mutual Funds Asset $ 5,543 $ 5,543 $ — $ — Real Estate Impairment For the year ended December 31, 2022, in connection with the preparation and review of the Company’s financial statements, the Company determined that eleven of the Company's properties were impaired based on shortened expected hold periods and expected selling prices. The Company considered these inputs as Level 3 measurements within the fair value hierarchy. The following table is a summary of the quantitative information related to the non-recurring fair value measurement for the impairment of the Company's real estate properties for the year ended December 31, 2022: Range of Inputs or Input Unobservable Inputs Midwest Properties Southwest Properties Market rent per square foot $8.50 to $12.75 $18.00- $23.00 Terminal capitalization rate 9.50% to 11.25% 7.23% - 7.75% Discount rate 10.25% to 14.00% 8.60% - 8.81% Range of Inputs or Input Unobservable Inputs Southern Property Northeast Properties Southwest Properties West Properties Expected selling price per square foot $295.96 $187 - $234 $268 $65 - $80 Estimated hold period Less than one year Less than one year Less than one year Less than one year Goodwill Impairment As a result of the updated composition of reporting units to align with the new segments, the Company concluded that it was more likely than not that the fair value of the Office reporting unit was less than the carrying amount, especially given the general decline in overall demand for office assets. Thus, the Company recorded a $135.3 million goodwill impairment. The Company estimated the fair value of real estate assets within the goodwill impairment calculation using a discounted cash flow model, including forecasted future cash flows based on significant assumptions such as market rent, and the determination of appropriate discount and terminal capitalization rates. The Company considered these inputs as Level 3 measurements within the fair value hierarchy. The following table is a summary of the quantitative information related to the non-recurring fair value measurement for the impairment of the Company's goodwill as it relates to the assets within the Office reporting unit for the year ended December 31, 2022: Range of Inputs or Input Unobservable Inputs Industrial Office Other Market rent per square foot $3.25- $27.00 $11.50 - $42.00 $4.00 - $27.50 Terminal capitalization rate 4.75% - 8.25% 5.75%- 9.50% 5.50% - 9.41% Discount rate 5.75% - 9.00% 6.25%- 10.50% 6.50%- 9.50% The Company also estimated the fair value of the mortgage loans within the goodwill impairment calculation as described in the Financial Instruments Disclosed at Fair Value section. The Company considered these inputs as Level 2 measurements within the fair value hierarchy. Refer to the table below for further details around the fair value of the mortgage loans. For the remaining assets and liabilities included within the goodwill calculation, the Company determined that amounts within the consolidated financial statements approximated fair value. Financial Instruments Disclosed at Fair Value Financial instruments as of December 31, 2022 and December 31, 2021 consisted of cash and cash equivalents, restricted cash, accounts receivable, accrued expenses and other liabilities, and mortgage payable and other borrowings, as defined in Note 5, Debt . With the exception of the mortgage loans in the table below, the amounts of the financial instruments presented in the consolidated financial statements substantially approximate their fair value as of December 31, 2022 and 2021. The fair value of the nine mortgage loans in the table below is estimated by discounting each loan’s principal balance over the remaining term of the mortgage using current borrowing rates available to the Company for debt instruments with similar terms and maturities. The Company determined that the mortgage debt valuation in its entirety is classified in Level 2 of the fair value hierarchy, as the fair value is based on current pricing for debt with similar terms as the in-place debt.

Equity [Abstract]
Equity	Equity Classes Class T shares, Class S shares, Class D shares, Class I shares, Class A shares, Class AA shares, Class AAA and Class E shares vote together as a single class, and each share is entitled to one vote on each matter submitted to a vote at a meeting of the Company's shareholders; provided that with respect to any matter that would only have a material adverse effect on the rights of a particular class of common shares, only the holders of such affected class are entitled to vote . The following table sets forth the classes of outstanding common shares as of December 31, 2022 and 2021: As of December 31, 2022 2021 Class A 2,714,120 2,723,286 Class AA 5,272,834 5,288,013 Class AAA 102,993 102,993 Class D 4,668 4,668 Class E 27,630,545 27,676,520 Class I 212,414 212,416 Class S 200 200 Class T 62,124 62,807 Common Equity As of December 31, 2022, the Company had received aggregate gross offering proceeds of approximately $2.8 billion from the sale of shares in the private offering, the public offerings, the DRP offerings and mergers (includes our Predecessor offerings and our Predecessor’s merger with Signature Office REIT, Inc., the Predecessor Mergers and the CCIT II Merger) , as discussed in Note 1, Organization . As part of the $2.8 billion from the sale of shares, the Company issued approximately 4,863,623 common shares upon the consummation of the merger of Signature Office REIT, Inc. in June 2015 and 19,442,394 Class E shares (in exchange for all outstanding shares of our Predecessor 's common stock at the time of the Predecessor Mergers) in April 2019 upon the consummation of the Predecessor Mergers and 10,384,185 Class E shares (in exchange for all the outstanding shares of CCIT II's common stock at the time of the CCIT II Merger). As of December 31, 2022, there were 35,999,898 shares outstanding, including shares issued pursuant to the DRP, less shares redeemed pursuant to the SRP and the self-tender offer, which occurred in May 2019. Distribution Reinvestment Plan (DRP) The Company has adopted the DRP, which allows shareholders to have dividends and other distributions otherwise distributable to them invested in additional common shares. No sales commissions or dealer manager fees will be paid on shares sold through the DRP, but the DRP shares will be charged the applicable distribution fee payable with respect to all shares of the applicable class. The purchase price per share under the DRP is equal to the net asset value ("NAV") per share applicable to the class of shares purchased, calculated using the most recently published NAV available at the time of reinvestment. The Company may amend or terminate the DRP for any reason at any time upon 10 days' prior written notice to shareholders, which may be provided through the Company's filings with the SEC. On July 17, 2020, the Company filed a registration statement on Form S-3 for the registration of up to $100 million in shares pursuant to the Company's DRP (the “DRP Offering”). The DRP Offering may be terminated at any time upon 10 days’ prior written notice to shareholders. On October 1, 2021, the Board approved a suspension of the DRP, effective October 11, 2021. The following table summarizes the DRP o fferings , by share class, as of December 31, 2022: Share Class Amount Shares Class A $ 9,687 116,908 Class AA 19,047 229,819 Class AAA 290 3,502 Class D 21 248 Class E 311,405 3,588,818 Class I 437 5,225 Class S — 1 Class T 177 2,121 Total $ 341,064 3,946,642 As of December 31, 2022 and 2021, the Company had issued approximately $341.1 million in shares pursuant to the DRP offerings, respectively. Share Redemption Program (SRP) Prior to its suspension in February 2023 in anticipation of the proposed listing of the Company’s common shares on the New York Stock Exchange (the “Listing”), the Company had adopted the SRP that enables shareholders to sell their shares to the Company in limited circumstances. The SRP was suspended on October 1, 2021 but resumed on a limited basis on August 5, 2022 (i.e., limited to redemptions in connection with a holder’s death, disability or incompetence) with the cap on quarterly redemptions tied to a dollar amount set by the Board and disclosed by the Company. Quarterly redemptions were capped at $5 million (or some other quarterly or annual amount determined by the Board and announced at least 10 business days before the applicable redemption date). In addition, during any calendar year, with respect to each share class, the Company was permitted to redeem no more than 5% of the weighted-average number of shares of such class outstanding during the prior calendar year. Under the SRP, when the SRP is not suspended, the Company will redeem shares as of the last business day of each quarter. The redemption price is equal to the most recently published NAV per share for the applicable class prior to quarter end. Redemption requests must be received by 3:00 p.m. (Central time) one business day before on the last business day of the applicable quarter. Redemption requests exceeding the quarterly cap are filled on a pro rata basis, except that if pro rata redemption would result in a shareholder owning less than the minimum balance of $2,500 of the Company's common shares, then the Company would redeem all of such shareholder’s shares to the extent that there are funds available. All unsatisfied redemption requests were treated as a request for redemption at the redemption date unless withdrawn by the shareholder. The following table summarizes share redemption (excluding the self-tender offer) activity during the years ended December 31, 2022 and 2021: Year Ended December 31, 2022 2021 Common shares redeemed 149,730 248,053 Weighted average price per share $ 66.79 $ 81.29 During the year ended December 31, 2022, the Company received redemption requests of common shares for approximately $15.9 million, which exceeded the limitation of approximately $10.0 million. Since July 31, 2014 and through December 31, 2022, the Company had redeemed 3,294,722 shares (excluding the self-tender offer) of common shares for approximately $275.5 million at a weighted average price per share of $83.61 pursuant to the SRP. Series A Preferred Shares On August 8, 2018, our Predecessor entered into a purchase agreement (the "Purchase Agreement") with SHBNPP Global Professional Investment Type Private Real Estate Trust No. 13(H) (acting through Kookmin Bank as trustee) (the "Purchaser") and Shinhan BNP Paribas Asset Management Corporation, as an asset manager of the Purchaser, pursuant to which the Purchaser agreed to purchase an aggregate of 10,000,000 shares of Series A Cumulative Perpetual Convertible Preferred Shares at a price of $25.00 per share (the "Series A Preferred Shares") in two tranches, each comprising 5,000,000 Series A Preferred Shares. On August 8, 2018 (the "First Issuance Date"), our Predecessor issued 5,000,000 Series A Preferred Shares to the Purchaser for a total purchase price of $125.0 million (the "First Issuance"). Our Predecessor paid transaction fees totaling 3.5% of the First Issuance purchase price and incurred approximately $0.4 million in transaction-related expenses to unaffiliated third parties. Our Predecessor’s former external advisor incurred transaction-related expenses of approximately $0.2 million, which was reimbursed by our Predecessor. Upon consummation of the Predecessor Mergers, the Company issued 5,000,000 Series A Preferred Shares to the Purchaser. Pursuant to the Purchase Agreement, the Purchaser has agreed to purchase an additional 5,000,000 Series A Preferred Shares (the "Second Issuance") at a later date (the "Second Issuance Date") for an additional purchase price of $125.0 million subject to approval by the Purchaser’s internal investment committee and the satisfaction of certain other conditions set forth in the Purchase Agreement. Pursuant to the Purchase Agreement, the Purchaser is generally restricted from transferring the Series A Preferred Shares or the economic interest in the Series A Preferred Shares for a period of five years from the applicable closing date. The issuance of the Company's Series A Preferred Shares was not registered under the Securities Act and are not listed on a national securities exchange. The articles supplementary filed by the Company related to the Series A Preferred Shares set forth the key terms of such shares as follows: Distributions Subject to the terms of the applicable articles supplementary, the holders of the Series A Preferred Shares are entitled to receive distributions quarterly in arrears at a rate equal to one-fourth (1/4) of the applicable varying rate, as follows: i. 6.55% from and after the First Issuance Date, or if the Second Issuance occurs, 6.55% from and after the Second Issuance Date until the five year anniversary of the First Issuance Date, or if the Second Issuance occurs, the five year anniversary of the Second Issuance Date (the “Reset Date”), subject to paragraphs (iii) and (iv) below; ii. 6.75% from and after the Reset Date, subject to paragraphs (iii) and (iv) below; iii. if a listing of the Company's Common Shares or the Series A Preferred Shares on a national securities exchange registered under Section 6(a) of the Exchange Act, does not occur by August 1, 2020 (the “First Triggering Event”), 7.55% from and after August 2, 2020 and 7.75% from and after the Reset Date, subject to (iv) below and certain conditions as set forth in the articles supplementary; or iv. if such a listing does not occur by August 1, 2021, 8.05% from and after August 2, 2021 until the Reset Date, and 8.25% from and after the Reset Date. Liquidation Preference Upon any voluntary or involuntary liquidation, dissolution or winding up of the Company, the holders of the Series A Preferred Shares will be entitled to be paid out of the Company's assets legally available for distribution to the shareholders, after payment of or provision for the Company's debts and other liabilities, liquidating distributions, in cash or property at its fair market value as determined by the Company's Board, in the amount, for each outstanding Series A Preferred Share equal to $25.00 per Series A Preferred Share (the "Liquidation Preference"), plus an amount equal to any accumulated and unpaid distributions to the date of payment, before any distribution or payment is made to holders of common shares or any other class or series of equity securities ranking junior to the Series A Preferred Shares but subject to the preferential rights of holders of any class or series of equity securities ranking senior to the Series A Preferred Shares. After payment of the full amount of the Liquidation Preference to which they are entitled, plus an amount equal to any accumulated and unpaid distributions to the date of payment, the holders of Series A Preferred Shares will have no right or claim to any of the Company's remaining assets. Company Redemption Rights The Series A Preferred Shares may be redeemed by the Company, in whole or in part, at the Company's option, at a per share redemption price in cash equal to $25.00 per Series A Preferred Share (the "Redemption Price"), plus any accumulated and unpaid distributions on the Series A Preferred Shares up to the redemption date, plus, a redemption fee of 1.5% of the Redemption Price in the case of a redemption that occurs on or after the date of the First Triggering Event, but before the date that is five years from the First Issuance Date. Holder Redemption Rights In the event the Company fails to effect a listing of the Company’s common shares or Series A Preferred Shares by August 1, 2023, the holder of any Series A Preferred Shares has the option to request a redemption of such shares on or on any date following August 1, 2023, at the Redemption Price, plus any accumulated and unpaid distributions up to the redemption date (the "Redemption Right"); provided, however, that no holder of the Series A Preferred Shares shall have a Redemption Right if such a listing occurs prior to or on August 1, 2023. Conversion Rights Subject to the Company's redemption rights and certain conditions set forth in the articles supplementary, a holder of the Series A Preferred Shares, at his or her option, will have the right to convert such holder's Series A Preferred Shares into the Company's common shares any time after the earlier of (i) five years from the First Issuance Date, or if the Second Issuance occurs, five years from the Second Issuance Date or (ii) a Change of Control (as defined in the articles supplementary) at a per share conversion rate equal to the Liquidation Preference divided by the then Common Share Fair Market Value (as defined in the articles supplementary). Issuance of Restricted Share Units to Executive Officers, Employees and Board of Trustees Restricted share units ("RSUs") are granted pursuant to the Company’s Amended and Restated Employee and Trustee Long-Term Incentive Plan (the “Plan”). The Plan provides for the grant of awards to the Company’s trustees, full-time employees and certain consultants that provide services to the Company or affiliated entities. Awards granted under the Plan may consist of stock options, restricted shares, share appreciation rights, distribution equivalent rights and other equity-based awards. The share-based payments are measured at fair value and recognized as compensation expense over the vesting period. The maximum number of shares authorized under the plan is 777,778 shares. As of December 31, 2022, approximately 357,806 shares were available for future issuance under the Plan. As of December 31, 2022, there was $10.8 million of unrecognized compensation expense remaining, which vests between three months and three years. Total compensation expense for the year ended December 31, 2022 and 2021 was approximately $9.6 million and $7.5 million, respectively. The following table summarizes the activity of unvested shares of RSU awards for the period presented: Number of Unvested Shares of RSU Awards Weighted-Average Grant Date Fair Value per Share Balance at December 31, 2020 104,871 Granted 179,917 $ 80.73 Forfeited (24,707) $ 81.88 Vested (90,235) $ 83.18 Balance at December 31, 2021 169,846 Granted 116,749 $ 66.87 Forfeited (9,404) $ 80.38 Vested (119,056) $ 77.68 Balance at December 31, 2022 158,135 Distributions Earnings and profits, which determine the taxability of distributions to shareholders, may differ from income reported for financial reporting purposes due to the differences for federal income tax purposes in the treatment of loss on debt, revenue recognition and compensation expense and in the basis of depreciable assets and estimated useful lives used to compute depreciation expense. The following unaudited table summarizes the federal income tax treatment for all distributions per share for the years ended December 31, 2022, 2021, and 2020 reported for federal tax purposes and serves as a designation of capital gain distributions, if applicable, pursuant to Code Section 857(b)(3)(C) and Treasury Regulation §1.857-6(e).

Noncontrolling Interest [Abstract]
Noncontrolling Interests	Noncontrolling Interests Noncontrolling interests represent limited liability company interests in the Operating Company in which the Company was the managing member. General partnership units and limited partnership units of the Operating Partnership were issued as part of the initial capitalization of the Operating Partnership and GCEAR II Operating Partnership, in conjunction with members of management's contribution of certain assets, other contributions, and in connection with the Self-Administration Transaction as discussed in Note 1, Organization, which were then exchanged for units . As of December 31, 2022, noncontrolling interests were approximately 9.0% of total shares and 8.8% of weighted average shares outstanding (both measures assuming OP Units were converted to common shares). The Company has evaluated the terms of the limited liability company interests in the Operating Company, and as a result, has classified OP Units exchanged for limited partnership interests issued in the initial capitalization, in conjunction with the contributed assets and in connection with the Self-Administration Transaction, as noncontrolling interests, which are presented as a component of permanent equity, except as discussed below. The Company evaluates individual noncontrolling interests for the ability to recognize the noncontrolling interest as permanent equity on the consolidated balance sheets at the time such interests are issued and on a continual basis. Any noncontrolling interest that fails to qualify as permanent equity has been reclassified as temporary equity and adjusted to the greater of (a) the carrying amount or (b) its redemption value as of the end of the period in which the determination is made. As of December 31, 2022, the members of the Operating Company owned approximately $31.8 million of OP Units, which were issued to affiliated parties and unaffiliated third parties in exchange for the contribution of certain properties to the Company, and in connection with the Self-Administration Transaction and other services In addition, 0.2 million OP Units were issued to unaffiliated third parties unrelated to property contributions. To the extent the contributors should elect to redeem all or a portion of their OP Units, pursuant to the terms of the respective contribution agreement, such redemption shall be at a per unit value equivalent to the price at which the contributor acquired its OP Units in the respective transaction. The members of the Operating Company (now partners in the Operating Partnership), other than those related to the Will Partners REIT, LLC ("Will Partners") property contribution, will have the right to cause the general partner of the Operating Partnership, the Company, to redeem their OP Units for cash equal to the value of an equivalent number of shares, or, at the Company’s option, purchase their OP Units by issuing one share of the Company’s common shares for the original redemption value of each OP Unit redeemed. The Company has the control and ability to settle such requests in shares. These rights may not be exercised under certain circumstances which could cause the Company to lose its REIT election. The following summarizes the activity for noncontrolling interests recorded as equity for the years ended December 31, 2022 and 2021: December 31, 2022 2021 Beginning balance $ 218,653 $ 226,550 Reclass of noncontrolling interest subject to redemption 957 (159) Repurchase of noncontrolling interest — — Issuance of stock dividend for noncontrolling interest — — Distributions to noncontrolling interests (10,942) (10,942) Allocated distributions to noncontrolling interests subject to redemption (17) (18) Net income (loss) (39,714) 66 Other comprehensive loss 5,718 3,156 Ending balance $ 174,655 $ 218,653 Noncontrolling interests subject to redemption OP Units issued pursuant to the Will Partners property contribution are not included in permanent equity on the consolidated balance sheets. The members holding these units can cause the general partner to redeem the units for the cash value, as defined in the partnership agreement of the Operating Partnership. As the general partner does not control these redemptions, these units are presented on the consolidated balance sheets as noncontrolling interest subject to redemption at their redeemable value. The net income (loss) and distributions attributed to these members are allocated proportionately between common shareholders and other noncontrolling interests that are not considered redeemable.

The terms of the Dealer Manager Agreement are substantially similar to the terms of the dealer manager agreement from the Company's initial public offering (“IPO”), except as it relates to the share classes offered and the fees to be received by the dealer manager. The Follow-On Offering terminated on September 20, 2020. See Note 9, Equity. Subject to the Financial Industry Regulatory Authority, Inc.'s limitations on underwriting compensation, under the Dealer Manager Agreement the Company required payment to the dealer manager of a distribution fee for ongoing services rendered to shareholders by participating broker-dealers or broker-dealers servicing investors’ accounts, referred to as servicing broker-dealers. The fee accrued daily, is paid monthly in arrears, and is calculated based on the average daily NAV for the applicable month. Conflicts of Interest Affiliated Former Dealer Manager Since Griffin Capital Securities, LLC, the Company's former dealer manager, is an affiliate of the Company's former sponsor, the Company did not have the benefit of an independent due diligence review and investigation of the type normally performed by an unaffiliated, independent underwriter in connection with the offering of securities. The Company's former dealer manager is also serving as the dealer manager for Griffin-American Healthcare REIT III, Inc. and Griffin-American Healthcare REIT IV, Inc., each of which are publicly-registered, non-traded REITs, as wholesale marketing agent for Griffin Institutional Access Real Estate Fund and Griffin Institutional Access Credit Fund both of which are non-diversified, closed-end management investment companies that are operated as interval funds under the 1940 Act, and as dealer manager or master placement agent for various private offerings. Administrative Services Agreement In connection with the Predecessor Mergers, the Company assumed, as the successor of our Predecessor and the Operating Partnership, an Administrative Services Agreement (the “Administrative Services Agreement”), pursuant to which Griffin Capital Company, LLC (“GCC”) and Griffin Capital, LLC (“GC LLC”) continue to provide certain operational and administrative services at cost to the Operating Partnership, Griffin Capital Essential Asset TRS, Inc., and Griffin Capital Real Estate Company, LLC (“GRECO”). Our Executive Chairman is also the Chief Executive Officer of and controls GCC, which is the sole member of GC LLC. The Company pays GCC a monthly amount based on the actual costs anticipated to be incurred by GCC for the provision of services until the Company elects to provide such services for itself or through another provider. Such costs are reconciled periodically and a full review of the costs will be performed at least annually. In addition, the Company will directly pay or reimburse GCC for the actual cost of any reasonable third-party expenses incurred in connection with the provision of such services. On March 30, 2022 and June 30, 2022, we amended the Administrative Services Agreement to, among other things, reduce the scope of services provided, including removing the provision of office space and advisor services. Following such amendments, GCC and GC LLC are obligated to provide us with human resources support and general corporate support on an as-needed basis. Office Sublease On March 25, 2022, the Company executed a sublease agreement with GCC (the “Sublease”) for the building located at 1520 E. Grand Ave, El Segundo, CA (the “Building”) which is the location of the Company’s corporate headquarters. The Building is part of a campus that contains other buildings and parking (the “Campus”). The Sublease also entitles the Company to use certain common areas on the Campus. Prior to the sublease agreement being signed, the rent for the office space was paid to GCC as part of the Administrative Services Agreement. The Campus is owned by GCPI, LLC (“GCPI”), and the Building is master leased by GCPI to GCC. GCC is the sublessor under the Sublease. The Company’s Executive Chairman is the Chief Executive Officer of and controls GCC and is also affiliated with GCPI. The Sublease provides for initial monthly base rent of $0.05 million, subject to annual escalations of 3% as well as additional rent for certain operating expenses for the Building and portions of the Campus. The Company’s Executive Chairman is the Chief Executive Officer of and controls GCC and is also affiliated with GCPI. Certain Conflict Resolution Procedures Every transaction that the Company enters into with affiliates is subject to an inherent conflict of interest. The Board may encounter conflicts of interest in enforcing the Company's rights against any affiliate in the event of a default by or disagreement with an affiliate or in invoking powers, rights or options pursuant to any agreement between the Company and its affiliates. See the Company's Code of Ethics and Business Conduct available on the “Governance Documents” subpage of the “Investors” section of the Company's website at www.pkst.com for a detailed description of the Company's conflict resolution procedures.

Leases [Abstract]
Leases	Leases Lessor The Company leases commercial and industrial space to tenants primarily under non-cancelable operating leases that generally contain provisions for minimum base rents plus reimbursement for certain operating expenses. Total minimum lease payments are recognized in rental income on a straight-line basis over the term of the related lease and estimated reimbursements from tenants for real estate taxes, insurance, common area maintenance and other recoverable operating expenses are recognized in rental income in the period that the expenses are incurred. The Company recognized $343.3 million, $378.3 million and $314.1 million of lease income The Company's current leases have expirations ranging from 2023 to 2044.

The Company’s ground leases are non-cancelable, and contain no renewal options. The Company's Chicago office space lease has a remaining lease term of approximately two years and no option to renew. The Company incurred operating lease costs of approximately $4.1 million for the years ended December 31, 2022 and $3.7 million for the year ended December 31, 2021 respectively, which are included in "Property Operating Expense" in the accompanying consolidated statement of operations.

Segment Reporting

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting In the fourth quarter of 2022, the Company evolved the management strategy of its real estate portfolio to focus on three different property types in order to maximize the value of the assets within each group. As a result, the Company changed to three reportable segments: Industrial, Office, and Other. The Industrial segment consists of high-quality, well-located industrial properties with modern specifications. The Office segment consists of newer, high-quality, and business-essential office properties. The Other segment consists of vacant and non-core properties, together with other properties in the same cross-collateralized loan pools. This segment includes properties that are either non-stabilized, leased to tenants with shorter lease terms or are being evaluated for repositioning, re-leasing or potential sale. The Company recast its segment results for all prior periods presented to show the three reportable segments. The Company evaluates performance of each segment based on segment NOI, which is defined as property revenue less property expenses. Interest expense and general administrative expenses are not included in segment profit as our internal reporting addresses these items on a corporate level. Segment NOI is not a measure of operating income or cash flows from operating activities is not indicative of cash available to fund cash needs and should not be considered an alternative to cash flows as a measure of liquidity. Not all companies calculate segment profit in the same manner. The Company considers segment profit to be an appropriate supplemental measure to net income because it assists both investors and management in understanding the core operations of our properties. Additionally, the Company considers its interests in the Office Joint Venture as corporate related activity and excludes such amounts from its segment reporting. A reconciliation of segment NOI for the years ended December 31, 2022, 2021, and 2020 is as follows: Year Ended December 31, 2022 2021 2020 Industrial NOI Total Industrial revenues $ 61,347 $ 59,320 $ 69,047 Industrial operating expenses (7,870) (7,195) (9,210) Industrial NOI 53,477 52,125 59,837 Office NOI Total Office revenues 297,110 340,265 268,928 Office operating expenses (66,143) (80,010) (70,815) Office NOI 230,967 260,255 198,113 Other NOI Total Other revenues 58,029 60,288 59,477 Other operating expenses (19,252) (19,369) (18,682) Other NOI 38,777 40,919 40,795 Total NOI $ 323,221 $ 353,299 $ 298,745 Year Ended December 31, 2022 2021 2020 Reconciliation of Net Income to Total NOI Net (loss) income $ (441,382) $ 11,570 $ (5,774) General and administrative expenses 39,893 40,479 38,633 Corporate operating expenses to affiliates 1,349 2,520 2,500 Impairment provision, real estate 127,577 4,242 23,472 Impairment provision, goodwill 135,270 — — Depreciation and amortization 190,745 209,638 161,056 Interest expense 84,816 85,087 79,646 Debt breakage costs 13,249 — — Other loss (income), net 45 (1,521) (3,228) Loss (income) from investment in unconsolidated entities 9,993 (8) 6,523 Loss (gain) from disposition of assets 139,280 326 (4,083) Transaction expense 22,386 966 — Total NOI $ 323,221 $ 353,299 $ 298,745 The following table presents the Company’s goodwill for each of the segments as of December 31, 2022 and 2021: Year Ended December 31, 2022 2021 Goodwill Industrial $ 68,373 $ 68,373 Office — 135,270 Other 26,305 26,305 Total Goodwill $ 94,678 $ 229,948 See Note 8, Fair Value Measurements , for details regarding the inputs used in determining the impairment of goodwill.

The Company maintains its cash accounts with major financial institutions. The cash balances consist of business checking accounts. These accounts are insured by the Federal Deposit Insurance Corporation up to $250,000 at each institution. The Company has not experienced any losses with respect to cash balances in excess of government provided insurance.
Restricted Cash	Restricted Cash In conjunction with acquisitions of certain assets, as required by certain lease provisions or certain lenders in conjunction with an acquisition or debt financing, or credits received by the seller of certain assets, the Company assumed or funded reserves for specific property improvements and deferred maintenance, re-leasing costs, and taxes and insurance, which are included on the consolidated balance sheets as restricted cash.
Real Estate Purchase Price Allocation	Real Estate Purchase Price Allocation The Company applies the provisions in ASC 805-10, Business Combinations ( " ASC 805-10"), to account for the acquisition of real estate, or real estate related assets, in which a lease, or other contract, is in place representing an active revenue stream, as an asset acquisition (or when applicable, a business combination). In accordance with the provisions of ASC 805-10 (on an asset acquisition), the Company recognizes the assets acquired, the liabilities assumed and any noncontrolling interest in the acquired entity at their relative fair values. The accounting provisions have also established that transaction costs associated with an asset acquisition are capitalized. Acquired in-place leases are valued as above-market or below-market as of the date of acquisition. The valuation is measured based on the present value (using an interest rate, which reflects the risks associated with the leases acquired) of the difference between (a) the contractual amounts to be paid pursuant to the in-place leases and (b) management’s estimate of fair market lease rates for the corresponding in-place leases over a period equal to the remaining non-cancelable term of the lease for above-market leases, taking into consideration below-market extension options for below-market leases. In addition, renewal options are considered and will be included in the valuation of in-place leases if (1) it is likely that the tenant will exercise the option, and (2) the renewal rent is considered to be sufficiently below a fair market rental rate at the time of renewal. The above-market and below-market lease values are capitalized as intangible lease assets or liabilities and amortized as an adjustment to rental income over the remaining terms of the respective leases. The aggregate relative fair value of in-place leases includes direct costs associated with obtaining a new tenant, opportunity costs associated with lost rentals, which are avoided by acquiring an in-place lease, and tenant relationships. Direct costs associated with obtaining a new tenant include commissions, tenant improvements, and other direct costs, and are estimated using methods similar to those used in independent appraisals and management’s consideration of current market costs to execute a similar lease. These direct costs are considered intangible lease assets and are included with real estate assets on the consolidated balance sheets. The intangible lease assets are amortized to expense over the remaining terms of the respective leases. The value of opportunity costs is calculated using the contractual amounts to be paid, including real estate taxes, insurance, and other operating expenses, pursuant to the in-place leases over a market lease-up period for a similar lease. Customer relationships are valued based on management’s evaluation of certain characteristics of each tenant’s lease and the Company’s overall relationship with that respective tenant. Characteristics management will consider in allocating these values include the nature and extent of the Company’s existing business relationships with tenants, growth prospects for developing new business with the tenant, the tenant’s credit quality and expectations of lease renewals (including those existing under the terms of the lease agreement), among other factors. These intangibles will be included in intangible lease assets on the consolidated balance sheets and are amortized to expense over the remaining term of the respective leases.
Depreciation and Amortization	Depreciation and Amortization The purchase price of real estate acquired and costs related to development, construction, and property improvements are capitalized. Repairs and maintenance costs include all costs that do not extend the useful life of the real estate asset and are expensed as incurred. The Company considers the period of future benefit of an asset to determine the appropriate useful life. The Company anticipates the estimated useful lives of its assets by class to be generally as follows: Buildings 25-40 years Building Improvements 5-20 years Land Improvements 15-25 years Tenant Improvements Shorter of estimated useful life or remaining contractual lease term Tenant Origination and Absorption Cost Remaining contractual lease term In-place Lease Valuation Remaining contractual lease term with consideration as to below-market extension options for below-market leases
Impairment of Real Estate and Related Intangible Assets	Impairment of Real Estate and Related Intangible Assets In accordance with the provisions of the Impairment or Disposal of Long-Lived Assets Subsections of ASC 360, the Company assesses the carrying values of our respective long-lived assets whenever events or changes in circumstances indicate that the carrying amounts of these assets may not be fully recoverable. Recoverability of real estate assets is measured by comparison of the carrying amount of the asset to the estimated future undiscounted cash flows. To review real estate assets for recoverability, the Company considers current market conditions as well as the Company's intent with respect to holding or disposing of the asset. The intent with regard to the underlying assets might change as market conditions and other factors change. Fair value is determined through various valuation techniques, including discounted cash flow models, applying a capitalization rate to estimated net operating income of a property, and quoted market values and third party appraisals, where considered necessary. The use of projected future cash flows is based on assumptions that are consistent with estimates of future expectations and the strategic plan used to manage the Company's underlying business. If the Company’s analysis indicates that the carrying value of the real estate asset is not recoverable on an undiscounted cash flow basis, the Company will recognize an impairment charge for the amount by which the carrying value exceeds the current estimated fair value of the real estate property.
Revenue Recognition	Revenue Recognition Leases associated with the acquisition and contribution of certain real estate assets have net minimum rent payment increases during the term of the lease and are recorded to rental revenue on a straight-line basis, commencing as of the contribution or acquisition date. If a lease provides for contingent rental income, the Company will defer the recognition of contingent rental income, such as percentage rents, until the specific target that triggers the contingent rental income is achieved. Tenant reimbursement revenue, which is comprised of additional amounts collected from tenants for the recovery of certain operating expenses, including repair and maintenance, property taxes (excluding taxes paid by a lessee directly to a third party on behalf of the lessor) and insurance, and capital expenditures, to the extent allowed pursuant to the lease (collectively, "Recoverable Expenses"), is recognized as revenue when the additional rent is due. Recoverable Expenses to be reimbursed by a tenant are determined based on the Company's estimate of the property's operating expenses for the year, pro-rated based on leased square footage of the property, and are collected in equal installments as additional rent from the tenant, pursuant to the terms of the lease. At the end of each quarter, the Company reconciles the amount of additional rent paid by the tenant during the quarter to the actual amount of the Recoverable Expenses incurred by the Company for the same period. The difference, if any, is either charged or credited to the tenant pursuant to the provisions of the lease. In certain instances, the lease may restrict the amount the Company can recover from the tenant, such as a cap on certain or all property operating expenses. In a situation in which a lease associated with a significant tenant has been, or is expected to be, terminated early, or extended, the Company evaluates the remaining useful life of amortizable assets in the asset group related to the lease that will be terminated (i.e. above- and below-market lease intangibles, in-place lease value and deferred leasing costs). Based upon consideration of the facts and circumstances surrounding the termination or extension, the Company may write-off or accelerate the amortization associated with the asset group. Such amounts are included within rental and other income for above- and below-market lease intangibles and amortization for the remaining lease related asset groups in the consolidated statements of operations.
Lease Accounting	Lease Accounting On January 1, 2019, the Company adopted ASC 842 using the modified retrospective approach and elected to apply the provisions as of the date of adoption on a prospective basis. Upon adoption of ASC 842, the Company elected the “package of practical expedients,” which allowed the Company to not reassess (a) whether expired or existing contracts as of January 1, 2019 are or contain leases, (b) the lease classification for any expired or existing leases as of January 1, 2019, and (c) the treatment of initial direct costs relating to any existing leases as of January 1, 2019. The package of practical expedients was made as a single election and was consistently applied to all leases that commenced before January 1, 2019. Lessor ASC 842 requires lessors to account for leases using an approach that is substantially equivalent to ASC 840 for sales-type leases, direct financing leases, and operating leases. As the Company elected the package of practical expedients, the Company's existing leases as of January 1, 2019 continue to be accounted for as operating leases. Upon adoption of ASC 842, the Company elected the practical expedient permitting lessors to elect by class of underlying asset to not separate nonlease components (for example, maintenance services, including common area maintenance) from associated lease components (the “non-separation practical expedient”) if both of the following criteria are met: (1) the timing and pattern of transfer of the lease and non-lease component(s) are the same and (2) the lease component would be classified as an operating lease if it were accounted for separately. If both criteria are met, the combined component is accounted for in accordance with ASC 842 if the lease component is the predominant component of the combined component; otherwise, the combined component is accounted for in accordance with the revenue recognition standard. The Company assessed the criteria above with respect to the Company's operating leases and determined that they qualify for the non-separation practical expedient. As a result, the Company accounted for and presented all rental income earned pursuant to operating leases, including property expense recovery, as a single line item, “Rental income,” in the consolidated statement of operations for all periods presented. Prior to the adoption of ASC 842, the Company presented rental income, property expense recovery and other income related to leases separately in the Company's consolidated statements of operations. Under ASC 842, lessors are required to record revenues and expenses on a gross basis for lessor costs (which include real estate taxes) when these costs are reimbursed by a lessee. Conversely, lessors are required to record revenues and expenses on a net basis for lessor costs when they are paid by a lessee directly to a third party on behalf of the lessor. Prior to the adoption of ASC 842, the Company recorded revenues and expenses on a gross basis for real estate taxes whether they were reimbursed to the Company by a tenant or paid directly by a tenant to the taxing authorities on the Company's behalf. Effective January 1, 2019, the Company is recording these costs in accordance with ASC 842. Lessee ASC 842 requires lessees to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right-of-use asset (“ROU asset”), which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. ASC 842 also requires lessees to classify leases as either finance or operating leases based on whether or not the lease is effectively a financed purchase of the leased asset by the lessee. This classification is used to evaluate whether the lease expense should be recognized based on an effective interest method or on a straight-line basis over the term of the lease. On January 1, 2019, the Company was the lessee on two ground leases, which were classified as operating leases under ASC 840. As the Company elected the packages of practical expedients, the Company is not required to reassess the classification of these existing leases and, as such, these leases continue to be accounted for as operating leases. On January 1, 2019, the Company recognized ROU assets and lease liabilities for these leases on the Company's consolidated balance sheets, and on a go-forward basis, lease expense will be recognized on a straight-line basis over the remaining term of the lease. On January 1, 2019, the Company recorded a ROU asset of $25.5 million and a corresponding liability of approximately $27.6 million relating to the Company's existing ground lease arrangements. These operating leases were recognized based on the present value of the future minimum lease payments over the lease term. As these leases do not provide an implicit rate, the Company used its incremental borrowing rate based on the information available in determining the present value of future payments. The discount rate used to determine the present value of these operating leases’ future payments was 5.36%. There was no impact to beginning equity as a result of the adoption related to the lessee accounting as the difference between the asset and liability is attributed to derecognition of pre-existing straight-line rent balances. Upon adoption of ASC 842, the Company also elected the practical expedient to not separate non-lease components, such as common area maintenance, from associated lease components for the Company's ground and office space leases.

Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities ASC 815, Derivatives and Hedging ("ASC 815") provides the disclosure requirements for derivatives and hedging activities with the intent to provide users of financial statements with an enhanced understanding of: (a) how and why an entity uses derivative instruments, (b) how the entity accounts for derivative instruments and related hedged items, and (c) how derivative instruments and related hedged items affect an entity’s financial position, financial performance, and cash flows. Further, ASC 815 requires qualitative disclosures regarding the Company’s objectives and strategies for using derivatives, as well as quantitative disclosures about the fair value of gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative instruments. As required by ASC 815, the Company recorded all derivatives on the consolidated balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, and whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain risks, even though hedge accounting does not apply or the Company elects not to apply hedge accounting. See Note 6, Interest Rate Contracts , for more detail.
Change in Consolidated Financial Statements Presentation	Principles of Consolidation The Company's financial statements, and the financial statements of the Operating Partnership, including its wholly-owned subsidiaries, are consolidated in the accompanying consolidated financial statements. The portion of these entities not wholly-owned by the Company is presented as noncontrolling interests. All significant intercompany accounts and transactions have been eliminated in consolidation. Consolidation Considerations Current accounting guidance provides a framework for identifying a variable interest entity (“VIE”) and determining when a company should include the assets, liabilities, noncontrolling interests, and results of activities of a VIE in its consolidated financial statements. In general, a VIE is an entity or other legal structure used to conduct activities or hold assets that either (1) has an insufficient amount of equity to carry out its principal activities without additional subordinated financial support, (2) has a group of equity owners that are unable to make significant decisions about its activities, or (3) has a group of equity owners that do not have the obligation to absorb losses or the right to receive returns generated by its operations. Generally, a VIE should be consolidated if a party with an ownership, contractual, or other financial interest in the VIE (a variable interest holder) has the power to direct the VIE’s most significant activities and the obligation to absorb losses or right to receive benefits of the VIE that could be significant to the VIE. A variable interest holder that consolidates the VIE is called the primary beneficiary. Upon consolidation, the primary beneficiary generally must initially record all of the VIE’s assets, liabilities, and noncontrolling interests at fair value and subsequently account for the VIE as if it were consolidated based on majority voting interest. See Note 4, Investments in Unconsolidated Entities, for more detail . The Company has determined that the Operating Partnership is a variable interest entity because the holders of limited partnership interests do not have substantive kick-out rights or participation rights. Furthermore, the Company is the primary beneficiary of the Operating Partnership because the Company has the obligation to absorb losses and the right to receive benefits from the Operating Partnership and the exclusive power to direct the activities of the Operating Partnership. As of December 31, 2022 and 2021, the assets and liabilities of the Company and the Operating Partnership are substantially the same, as the Company does not have any significant assets other than its investment in the Operating Partnership.
Income Taxes	Income Taxes The Company has elected to be taxed as a REIT under the Internal Revenue Code ("Code"). To qualify as a REIT, the Company must meet certain organizational and operational requirements. The Company intends to adhere to these requirements and maintain its REIT status for the current year and subsequent years. As a REIT, the Company generally will not be subject to federal income taxes on taxable income that is distributed to shareholders. However, the Company may be subject to certain state and local taxes on its income and property, and federal income and excise taxes on its undistributed taxable income, if any. If the Company fails to qualify as a REIT in any taxable year, the Company will then be subject to federal income taxes on the taxable income at regular corporate rates and will not be permitted to qualify for treatment as a REIT for federal income tax purposes for four years following the year during which qualification is lost unless the Internal Revenue Service ("IRS") grants the Company relief under certain statutory provisions. Such an event could materially adversely affect net income and net cash available for distribution to shareholders. As of December 31, 2022, the Company satisfied the REIT requirements and distributed all of its taxable income.
Goodwill	Goodwill Goodwill arises from business combinations and represents the excess of the cost of an acquired entity over the net fair value amounts that were assigned to the identifiable assets acquired and the liabilities assumed. The Company recorded goodwill as a result of the transaction that resulted in the internalization of GRT management in December 2018 (“Self-Administration Transaction”). The Company’s goodwill has an indeterminate life and is not amortized, but is tested for impairment on an annual basis for each reporting unit, or more frequently if events or changes in circumstances indicate that the asset is more likely than not impaired. On October 1st of each period, the Company performs a qualitative analysis to determine whether an impairment of goodwill exists prior to quantitatively determining the fair value of the reporting units in step one of the impairment test. If a quantitative assessment is deemed necessary, and to the extent the carrying amount of the reporting unit’s allocated goodwill exceeds the unit’s fair value, the Company recognizes an impairment of goodwill for the excess up to the amount of goodwill of that reporting unit. Due to the Company’s operating segment realignment in the fourth quarter of 2022, the composition of its reporting units for the evaluation of goodwill impairment was changed and resulted in a quantitative assessment of goodwill impairment. Prior to the change, the Company tested the goodwill for impairment at the previous single reporting unit, which did not result in any impairment charge. Goodwill is now allocated across all three of the Company’s Office, Industrial, and Other reporting units on a relative fair value basis, which is determined as the fair value of assets less liabilities for each reporting unit. Given this method, the fair value of real estate assets and mortgage loans included within each reporting unit were the significant components in determining relative fair value. The Company estimated the fair value of real estate assets using a discounted cash flow model, including forecasted future cash flows based on significant assumptions such as market rent, and the determination of appropriate discount and terminal capitalization rates. The Company estimated the fair value of the mortgage loans in each reporting unit by discounting each loan’s principal balance over the remaining term of the mortgage using current borrowing rates available to the Company for debt instruments with similar terms and maturities. The Company determined that the amounts within the consolidated financial statements for the remaining assets and liabilities approximated fair value. For any corporate related amounts that were not specifically identifiable to any reporting unit, the Company allocated those amounts on a relative fair value basis using the specifically identified assets and liabilities. As a result of the quantitative assessment as of December 31, 2022, the Company concluded that it was more likely than not that the fair value of the Office reporting unit was less than the carrying amount, especially given the general decline in overall demand for office assets. Thus, the Company recorded a $135.3 million goodwill impairment, which represents the entire amount of goodwill allocated to the Office segment. See Note 8, Fair Value Measurements , for details regarding the inputs used in determining the impairment of goodwill. See Note 14, Segment Reporting , for allocation of goodwill for each of the Company’s segments.
Use of Estimates	Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the unaudited consolidated financial statements and accompanying notes. Actual results could materially differ from those estimates.
Per Share Data	Per Share DataThe Company reports earnings per share for the period as (1) basic earnings per share computed by dividing net income (loss) attributable to common shareholders by the weighted average number of common shares outstanding during the period, and (2) diluted earnings per share computed by dividing net income (loss) attributable to common shareholders by the weighted average number of common shares outstanding, including common shares equivalents. Unvested RSUs that contain non-forfeitable rights to dividends are participating securities and are included in the computation of earnings per share pursuant to the two-class method. The effect of including unvested restricted shares using the treasury stock method was excluded from our calculation of weighted average common shares outstanding – diluted, as the inclusion would have been anti-dilutive for the years ended December 31, 2022, 2021 and 2020.
Segment Information	Segment InformationIn the fourth quarter of 2022, the Company evolved the management strategy of its real estate portfolio to focus on three different property types in order to maximize the value of the assets within each group. As a result, the Company changed to three reportable segments: Industrial, Office, and Other. The Industrial segment consists of high-quality, well-located industrial properties with modern specifications. The Office segment includes newer, high-quality, and business-essential office properties. The Other segment consists of vacant and non-core properties, together with other properties in the same cross-collateralized loan pools. This segment includes properties that are either non-stabilized, leased to tenants with shorter lease terms or are being evaluated for repositioning, re-leasing or potential sale. The Company recast its segment results for all prior periods presented to show the three reportable segments.
Unaudited Data	Unaudited DataAny references to the number of buildings, square footage, number of leases, occupancy, and any amounts derived from these values in the notes to the consolidated financial statements are unaudited and outside the scope of the Company's independent registered public accounting firm's audit of its consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board ("PCAOB").
Recently Issued Accounting Pronouncements and Adoption of New Accounting Pronouncements	Recently Issued Accounting Pronouncements Changes to GAAP are established by the FASB in the form of ASUs to the FASB’s Accounting Standards Codification. The Company considers the applicability and impact of all ASUs. Other than the ASUs discussed below, the FASB has not recently issued any other ASUs that the Company expects to be applicable and have a material impact on the Company's financial statements. Adoption of New Accounting Pronouncements In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”). ASU 2020-04 provides temporary optional guidance that provides transition relief for reference rate reform, including optional expedients and exceptions for applying GAAP to contract modifications, hedging relationships and other transactions that reference LIBOR or a reference rate that is expected to be discontinued as a result of reference rate reform if certain criteria are met. ASU 2020-04 is effective upon issuance, and the provisions generally can be applied prospectively as of January 1, 2020 through December 31, 2023. During the first quarter of 2020, the Company elected to apply the hedge accounting expedients related to probability and the assessments of effectiveness for future LIBOR-indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. The Company has subsequently elected to apply additional expedients related to
