Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization On October 4, 2004, InvenTrust Properties Corp. (the "Company") was incorporated as Inland American Real Estate Trust, Inc., as a Maryland corporation and has elected to be taxed, and currently qualifies, as a real estate investment trust ("REIT") for federal tax purposes. The Company changed its name to InvenTrust Properties Corp. in April of 2015 and is focused on owning, managing, acquiring and developing a multi-tenant retail platform. The accompanying consolidated financial statements include the accounts of the Company, as well as all wholly-owned subsidiaries. Subsidiaries generally consist of limited liability companies ("LLCs") and limited partnerships ("LPs"). All significant intercompany balances and transactions have been eliminated. Each retail property is owned by a separate legal entity that maintains its own books and financial records. Each separate legal entity's assets are not available to satisfy the liabilities of other affiliated entities, except as otherwise disclosed in " Note 6. Investment in Unconsolidated Entities ". As of December 31, 2020 and 2019, the Company had an investment in one unconsolidated real estate joint venture, as disclosed in " Note 6. Investment in Unconsolidated Entities ". The Company determined it has a single reportable segment, multi-tenant retail, for disclosure purposes in accordance with United States ("U.S.") generally accepted accounting principles ("GAAP"). Unless otherwise noted, all dollar amounts are stated in thousands, except share, per share and per square foot data. Number of properties and square feet are unaudited. The following table summarizes the Company's retail portfolio as of December 31, 2020 and 2019: Wholly-Owned Unconsolidated 2020 2019 2020 2019 No. of properties 55 54 10 11 Gross Leasable Area (square feet) 8,392,572 8,311,521 2,470,193 2,580,414 Impact of the COVID-19 Pandemic on the Company's Consolidated Financial Statements The Company's business has been, and continues to be, disrupted by the coronavirus disease 2019 ("COVID-19") pandemic. The Company continues to assess the ongoing impact of the COVID-19 pandemic on all aspects of its business, including the impact on its tenants and their ability to make future rental payments in a timely fashion or at all and the possible impairment in value of our investment properties. During the year ended December 31, 2020, deferred rental payments of $1,583 became due and payable; the Company has collected $1,379 as of December 31, 2020. During the year ended December 31, 2020, the Company had granted approximately $5,791 of rental payment deferrals, with contractual payment terms through the year ended December 31, 2023.

Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies Estimates, Risks, and Uncertainties The accompanying consolidated financial statements have been prepared in accordance with GAAP, which requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Significant estimates, judgments and assumptions are required in a number of areas, including, but not limited to, evaluating the impairment of long-lived assets, allocating the purchase price of acquired retail properties, determining the fair value of debt and evaluating the collectability of accounts receivable. The Company bases these estimates, judgments and assumptions on historical experience and various other factors that the Company believes to be reasonable under the circumstances. Actual results may differ from these estimates. Reclassifications The Company has made certain reclassifications to the consolidated statements of operations and comprehensive (loss) income for the years ended December 31, 2019 and 2018 to conform to the 2020 presentation, including amounts previously reported as realized and unrealized gains on marketable securities and income tax expense now reported as other income and expense, net. The Company has made certain reclassifications to the consolidated statements of cash flows for the years ended December 31, 2019 and 2018 to conform to the 2020 presentation, including amounts previously reported as accounts and rents receivable, net, now reported as provision for estimated credit losses. These reclassifications to the consolidated statements of cash flows for the years ended December 31, 2019 and 2018 are limited to changes in presentation and did not result in any change to overall cash flows from operating activities. Variable Interest Entities The Company evaluates its investments in LLCs and LPs to determine whether each such entity may be a variable interest entity ("VIE"). The accounting standards related to the consolidation of VIEs require qualitative assessments to determine whether the Company is the primary beneficiary. Determination of the primary beneficiary is based on whether the Company has (i) power to direct significant activities of the VIE and (ii) an obligation to absorb losses or the right to receive benefits that could be potentially significant to the VIE. The Company consolidates a VIE if it is deemed to be the primary beneficiary. The equity method of accounting is applied to entities in which the Company is not the primary beneficiary, or if the entity is not a VIE and the Company does not have control, but can exercise significant influence over the entity with respect to its operations and major decisions. As of December 31, 2020 and 2019, the Company had no VIEs. Revenue Recognition Adoption of Topic 842 In conjunction with the adoption of Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 842, Leases , ("Topic 842") on January 1, 2019, the Company elected the package of practical expedients which permitted the Company to not reassess: (1) whether any expired or existing contracts are, or contain leases; (2) the lease classification for any expired or existing leases; and (3) any initial direct costs for existing leases as of the effective date. Except as described below, the Company's accounting policies and resulting recognition of lease income remained substantially consistent with previous guidance. In addition, the Company has elected the practical expedient of not separating lease and non-lease components for all qualifying leases. In effect, this generally relieves the Company from the requirement to account for certain consideration under FASB ASC 606, Revenue from Contracts with Customers ("Topic 606"). As a result of the accounting policy election, all income arising from leases is presented on a combined basis as lease income, net on the consolidated statements of operations and comprehensive (loss) income. As a result of the narrowed definition of initial direct costs under Topic 842, the Company expenses as incurred certain lease origination costs previously capitalized and amortized to expense over the lease term. Lease Income The majority of revenue recognized from the Company's retail properties is comprised of fixed and variable consideration received from tenants under long-term operating leases with varying terms. Fixed consideration generally consists of minimum lease payments for the rental of retail space while the variable consideration generally consists of reimbursements of the tenant's pro-rata share of certain operating expenses incurred by the Company, including real estate taxes, special assessments, insurance, utilities, common area maintenance, management fees and certain capital repairs. Certain other tenants are subject to net leases whereby the tenant is responsible for fixed minimum lease payments to the Company, as well as directly paying all costs and expenses associated with occupancy to third party service providers. Such direct payments to third parties are not recorded as revenue and expense by the Company. Minimum lease payments are recognized on a straight-line basis over the term of each lease. The cumulative difference between fixed consideration recognized on a straight-line basis and the cash payments due under the provisions of the lease agreements is recorded as deferred rent receivable and is included as a component of accounts and rents receivable on the consolidated balance sheets. The Company records lease termination income when all conditions of a signed termination agreement have been met, the tenant is no longer occupying the property, and termination income amounts due are considered collectible. The Company defers recognition of contingent lease income until the specified target that triggers the contingent lease income is achieved. The Company commences revenue recognition on its leases when the lessee takes possession of, or controls the physical use of, the leased asset, unless the lessee is constructing improvements for which the Company is deemed to be the owner for accounting purposes. If the Company is deemed the owner for accounting purposes, the leased asset is the finished space and revenue recognition commences when the lessee takes possession of it, typically when the improvements are substantially complete. Alternatively, if the lessee is deemed to be the owner of the improvements for accounting purposes, then the leased asset is the unimproved space, and any tenant improvement allowances funded under the lease are treated as lease incentives, which reduce lease income recognized over the lease term, and the Company commences revenue recognition when the lessee takes possession of the unimproved space. The determination of who owns the tenant improvements, for accounting purposes, is based on contractual rights and subject to judgment. In making that judgment, no one factor is determinative. The Company routinely considers: • whether the lease stipulates how and on what a tenant improvement allowance may be spent; • whether the tenant is required to provide evidence supporting the cost of improvements prior to reimbursement; • whether the tenant or landlord retains legal title to the improvements; • the uniqueness of the improvements; • the expected economic life of the tenant improvements relative to the length of the lease; and • who constructs or directs the construction of the improvements. Staff Q&A, Topic 842 and Topic 840: Accounting for Lease Concessions Related to the Effects of the COVID-19 Pandemic In April 2020, the FASB issued a document titled Staff Q&A, Topic 842 and Topic 840: Accounting for Lease Concessions Related to the Effects of the COVID-19 Pandemic ("FASB Q&A document"). The FASB Q&A document permits an election whereby an entity is not required to evaluate whether certain relief provided by a lessor in response to the COVID-19 pandemic is a lease modification (the "COVID-19 election"). An entity that makes this election can then either apply the modification guidance to that relief or account for the concession as if it were contemplated as part of the existing contract. This election is available for concessions related to the effects of the COVID-19 pandemic that do not result in a substantial increase in the rights of the lessor or the obligations of the lessee. In response to receiving numerous rent relief requests, the Company has adopted the COVID-19 election, under which lease amendments providing tenants with COVID-19 related rent relief are not treated as lease modifications unless: • the total payments required by the amended lease are not substantially equal to or less than the total payments required by the original lease; or • the amended lease results in an increase to the lease term. Rent relief has most frequently been requested in the form of deferral of rental payments. A deferral affects the timing of cash receipts, but the amount of consideration is substantially the same as that required by the original lease. Under the Company's COVID-19 election, deferrals are accounted for as if no changes to the lease contract were made. The Company continues to recognize rental income and increase lease receivables during the deferral period. Rent abatements or other reductions in total payments are treated as negative variable rent in the period to which the rent relates. Credit Losses The Company reviews the collectability of amounts due from its tenants on a regular basis. Such reviews consider the tenant's financial condition and payment history and other economic conditions impacting the tenant. Changes in collectability occur when the Company no longer believes it is probable that substantially all the lease payments will be collected over the term of the lease. If collection is not probable, regardless of whether the Company has entered into an amendment to provide the tenant with COVID-19 related rent relief, the lease payments will be accounted for on a cash basis, and revenue will be recorded as cash is received. If reassessed, and the collection of substantially all of the lease payments from the tenant becomes probable, the accrual basis of revenue recognition is reestablished. Beginning on January 1, 2019, the provision for estimated credit losses resulting from changes in the expected collectability of lease payments, including variable payments, is recognized as a direct adjustment to lease income on the consolidated statements of operations and comprehensive (loss) income, and a direct write-off of the operating lease receivables, including straight-line rent receivable, on the consolidated balance sheets. The Company continues to evaluate the impact of the COVID-19 pandemic on its ability to collect future lease payments under the terms of the respective leases. As the duration and severity of the COVID-19 pandemic are still uncertain and continue to evolve, uncertainty exists regarding the Company's provision for estimated credit losses for deferred rental payments receivable, billed rent and straight-line rent receivables. Other Fee Income The Company recognizes other fee income when it satisfies a performance obligation relating to services provided to its joint venture partnership. The resulting receivables are settled through recurring monthly payments for the services provided over the term of the contract. The Company generally does not receive prepayments for services or recognize revenue prior to being legally entitled to payment. As a result, the Company does not generally record contract assets or contract liabilities. Property management and asset management fees are recognized over time as services are rendered to the joint venture partnership. The bundled services of the property management performance obligation and asset management performance obligation each qualify as a series of distinct services satisfied over time. The variable consideration related to each of the performance obligations is recognized in each of the periods that directly relate to the Company's efforts to provide those services. Accordingly, the Company elected the optional exemption provided by Topic 606 to not disclose information about remaining wholly unsatisfied performance obligations. The variability in timing of the property management and asset management fees, which generally relate to the fluctuation in cash receipts from tenants and potential changes in equity capitalization, are resolved on a monthly basis. For certain services, the Company acts as an agent on behalf of the customer to arrange for performance by a third party. Based on the Company's judgment, both the underlying asset management service activities and the underlying property management service activities are not distinct but are inputs (or fulfillment activities) to provide the combined output (either the overall asset management service or the overall property management service). Leasing commissions and other fees are recognized at a point in time consistent with the underlying service rendered to the joint venture partnership. The leasing performance obligation and other performance obligations are satisfied at the point in which the customer is transferred control over and consumes the benefit of the service. The uncertainty of the leasing commissions and other fees are resolved upon delivery of the underlying service. Generally, the first and second installments of leasing commissions are paid upon lease execution and rent commencement, respectively. Sale of Real Estate The Company derecognizes real estate and recognizes a gain or loss when a contract exists and control of the property has transferred to the buyer. Control of the property, including controlling financial interest, is generally considered to transfer upon closing through transfer of the legal title and possession of the property, at which point the Company recognizes a gain or loss equal to the difference between the transaction price and the carrying amount of the property. Acquisition of Real Estate The Company evaluates the inputs, processes and outputs of each asset acquired to determine if the transaction is a business combination or asset acquisition. If an acquisition qualifies as a business combination, the related transaction costs are recorded as an expense in the consolidated statements of operations and comprehensive (loss) income. If an acquisition qualifies as an asset acquisition, the related transaction costs are generally capitalized and amortized over the useful life of the acquired assets. Generally, acquisition of real estate qualifies as an asset acquisition. The Company allocates the purchase price of real estate to land, building, other building improvements, tenant improvements, intangible assets and liabilities (such as the value of above- and below-market leases, in-place leases and origination costs associated with in-place leases). The values of above- and below-market leases are recorded as intangible assets, net, and intangible liabilities, net, respectively, on the consolidated balance sheets, and are amortized as either a decrease (in the case of above-market leases) or an increase (in the case of below-market leases) to lease income over the remaining term of the associated tenant lease. The values, if any, associated with in-place leases are recorded in intangible assets, net, on the consolidated balance sheets and are amortized to depreciation and amortization expense on the consolidated statements of operations and comprehensive (loss) income over the remaining lease term. The difference between the contractual rental rates and the Company's estimate of market rental rates is measured over a period equal to the remaining non-cancelable term of the leases plus the term of any below-market renewal options. For the amortization period, the remaining term of leases with renewal options at terms below market reflect the assumed exercise of such below-market renewal options, if reasonably assured. If a tenant vacates its space prior to the contractual expiration of the lease and no rental payments are being made on the lease, any unamortized balance of the related intangible asset or liability is written off. Tenant improvements are depreciated and origination costs are amortized over the remaining term of the lease or charged against earnings if the lease is terminated prior to its contractual expiration date. The Company performs, with the assistance of a third-party valuation specialist, the following procedures for assets acquired: • Estimate the value of the property "as if vacant" as of the acquisition date; • Allocate the value of the property among land, building, and other building improvements and determine the associated useful life for each; • Calculate the value and associated life of above- and below-market leases on a tenant-by-tenant basis. The difference between the contractual rental rates and the Company’s estimate of market rental rates is measured over a period equal to the remaining term of the leases (using a discount rate which reflects the risks associated with the leases acquired, including geographical location, size of leased area, tenant profile and credit risk); • Estimate the fair value of the tenant improvements, legal costs and leasing commissions incurred to obtain the leases and calculate the associated useful life for each; • Estimate the fair value of assumed debt, if any; and • Estimate the intangible value of the in-place leases based on lease execution costs of similar leases as well as lost rent payments during an assumed lease-up period and their associated useful lives on a tenant-by-tenant basis. Properties Held for Sale In determining whether to classify a property as held for sale, the Company considers whether: (i) management has committed to a plan to sell the property; (ii) the property is available for immediate sale, in its present condition; (iii) the Company has initiated a program to locate a buyer; (iv) the Company believes that the sale of the property is probable; (v) the Company has received a significant non-refundable deposit for the purchase of the property; (vi) the Company is actively marketing the property for sale at a price that is reasonable in relation to its estimated fair value; and (vii) actions required for the Company to complete the plan indicate that it is unlikely that any significant changes will be made to the plan. When all criteria are met, the property is classified as held for sale and carried at the lower of cost or estimated fair value less costs to sell. Additionally, if the sale represents a strategic shift that has (or will have) a major effect on the Company's results and operations, the income and expenses for the period are classified as discontinued operations on the consolidated statements of operations and comprehensive (loss) income for all periods presented. Impairment of Long Lived Assets The Company assesses the carrying values of long-lived tangible and intangible assets whenever events or changes in circumstances indicate that the carrying amounts of these assets may not be fully recoverable, such as a reduction in the expected holding period of a property. If it is determined that the carrying value is not recoverable because the expected undiscounted cash flows do not exceed that carrying value, the Company records an impairment loss to the extent that the carrying value exceeds the estimated fair value. The valuation and possible subsequent impairment of investment properties is a significant estimate that can and does change based on the Company's continuous process of analyzing each property's economic condition at a point in time and reviewing assumptions about uncertain inherent factors, including observable inputs such as contractual revenues and unobservable inputs such as forecasted revenues and expenses, estimated net disposition proceeds, and discount rate. These unobservable inputs are based on a property's market conditions and expected growth rates. However, assumptions and estimates about future cash flows and capitalization rates are complex and subjective. Changes in economic and operating conditions and the Company's ultimate investment intent that occur subsequent to the impairment analyses could impact these assumptions and result in additional impairment of the investment properties. Periodically, management assesses whether there are any indicators that the carrying value of the Company's investments in unconsolidated entities may be other-than-temporarily impaired. To the extent other-than-temporary impairment has occurred, the loss is measured as the excess of the carrying value of the investment over the estimated fair value of the investment. The estimated fair value of the investment is generally derived from the cash flows generated from the underlying real property investments of the investee. Real Estate Capitalization and Depreciation Real estate is reflected at cost less accumulated depreciation within investment properties on the consolidated balance sheets. Ordinary repairs and maintenance are expensed as incurred. Depreciation expense is computed using the straight-line method. A range of estimated useful lives of 15-30 years is used for buildings and other improvements, and a range of 5-20 years is used for furniture, fixtures and equipment. Finance lease asset amortization is computed using the straight-line method over the lease term and included in depreciation and amortization on the consolidated statements of operations and comprehensive (loss) income. Tenant improvements not of use to subsequent tenants are amortized on a straight-line basis over the lesser of the life of the tenant improvement or the lease term. Amortization is included in depreciation and amortization on the consolidated statements of operations and comprehensive (loss) income. Deferred leasing costs are recognized as a part of deferred costs and other assets, net, on the consolidated balance sheets and are amortized to depreciation and amortization on the consolidated statements of operations and comprehensive (loss) income over the remaining term of the associated tenant lease. Direct and indirect costs that are clearly related to the construction and improvements of investment properties are capitalized. Costs incurred for interest, property taxes and insurance are capitalized during periods in which activities necessary to prepare the property for its intended use are in progress. Cash and Cash Equivalents The Company considers all demand deposits, money market accounts and investments in certificates of deposit and repurchase agreements with a maturity of three months or less, at the date of purchase, to be cash equivalents. The Company maintains its cash and cash equivalents at financial institutions. The combined account balances at one or more institutions generally exceed the Federal Deposit Insurance Corporation ("FDIC") insurance coverage. The Company periodically assesses the credit risk associated with these financial institutions. There is what the Company believes to be insignificant credit risk related to amounts on deposit in excess of FDIC insurance coverage. Restricted Cash Restricted cash consists of lenders’ escrows, operating real estate escrows for taxes, insurance, capital expenditures and payments required under certain lease agreements, and funds restricted through lender or other agreements, including funds held in escrow for future acquisitions. Derivative Instruments In the normal course of business, the Company is exposed to the effect of interest rate changes. The Company's objective in using interest rate derivatives is to manage its exposure to interest rate movements and add stability to interest expense. To accomplish this objective, the Company uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable rate amounts from a counterparty in exchange for the Company making fixed rate payments over the life of the agreement without exchange of the underlying notional amount. The Company has a policy of only entering into contracts with established financial institutions based upon their credit ratings and other factors. When viewed in conjunction with the underlying and offsetting exposure that the derivatives are designed to hedge, the Company has not sustained a material loss from those instruments, nor does it anticipate any material adverse effect on its net income or financial position in the future from the use of derivatives. The Company recognizes all derivatives on the consolidated balance sheets at fair value. Additionally, the fair value adjustments will affect either equity or net income depending on whether the derivative instruments qualify as a hedge for accounting purposes and, if so, the nature of the hedging activity. When the underlying transaction is terminated or completed, all changes in the fair value of the instrument are marked-to-market with changes in value included in net income each period until the instrument matures. Any derivative instrument used for risk management that does not meet the criteria for hedge accounting is marked-to-market each period on the consolidated statements of operations and comprehensive (loss) income. The Company does not use derivatives for trading or speculative purposes. Fair Value Measurements In accordance with FASB ASC 820, Fair Value Measurement and Disclosures ("Topic 820"), the Company defines fair value based on the price that would be received upon sale of an asset or the exit price that would be paid to transfer or settle a liability in an orderly transaction between market participants at the measurement date. The Company uses a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value. The fair value hierarchy consists of the three broad levels described below: • Level 1 - Quoted prices in active markets for identical assets or liabilities that the entity has the ability to access. • Level 2 - Observable inputs, other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. • Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs. The Company has estimated the fair value of its financial instruments and non-financial assets using available market information and valuation methodologies the Company believes to be appropriate for these purposes. Considerable judgment and a high degree of subjectivity are involved in developing these estimates and, accordingly, they are not necessarily indicative of amounts that would be realized upon disposition. The carrying amounts of cash and cash equivalents, restricted cash, accounts and rents receivables, other assets, accounts payable, accrued expenses and other liabilities reasonably approximate fair value, in management’s judgment, because of their short-term nature. Fair value information pertaining to derivative financial instruments, investment properties, investments in unconsolidated entities and debt is provided in "Note 9. Fair Value Measurements" . Income Taxes The Company is qualified and has elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the "Code") for federal income tax purposes commencing with the tax year ended December 31, 2005. Since the Company qualifies for taxation as a REIT, the Company generally is not subject to federal income tax on taxable income distributed to stockholders. To continue to qualify as a REIT, the Company generally is required to distribute at least 90% of its REIT taxable income (subject to certain adjustments) to its stockholders each year (the "90% Distribution Requirement"). If the Company fails to qualify as a REIT in any taxable year, without the benefit of certain relief provisions, the Company will be subject to federal and state income tax on its taxable income at regular corporate tax rates. Even if the Company qualifies for taxation as a REIT, the Company may be subject to certain state and local taxes on its income, property or net worth and federal income and excise taxes on its undistributed income. From time to time, the Company may elect to treat certain of its consolidated subsidiaries as taxable REIT subsidiaries ("TRSs") pursuant to the Code. Among other activities, TRSs may participate in non-real estate related activities and/or perform non-customary services for tenants and are subject to federal and state income tax at regular corporate tax rates. During 2020, the Company either revoked the TRS elections or dissolved the legal entities for any of its consolidated subsidiaries that were TRSs. The Company accounts for income taxes using the asset and liability method under which deferred tax assets and liabilities are recognized for the estimated future tax consequences attributed to differences between the GAAP carrying amounts of existing assets and liabilities and their respective tax bases. In assessing the realizability of the resulting deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. As of December 31, 2019, Management determined it was more likely than not that the Company would not have realized $26,427 of benefits relating to deductible differences. Accordingly, a valuation allowance was recognized to reduce the deferred tax assets to zero. At the time of revocation or liquidation in 2020, the TRSs had approximately $26,153 of gross deferred tax asset and a corresponding valuation allowance of $26,153. As a result, both the gross deferred tax asset and valuation allowance were reversed resulting in a net zero impact to both the net deferred tax asset and income tax expense. As of December 31, 2020, the Company has no significant deferred tax assets/liabilities. Income tax expense for the years ended December 31, 2020, 2019 and 2018 is generally comprised of federal and state taxes paid by consolidated TRSs and certain state taxes paid by the Company. Under the federal legislation enacted on March 27, 2020, known as the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act"), certain limitations on the deductibility of net operating losses ("NOLs") enacted under prior federal tax legislation have been temporarily rolled back. In particular, the CARES Act permits businesses to carryback NOLs generated in taxable years beginning after December 31, 2017 and before January 1, 2021 to the previous five years and temporarily suspends, until taxable years beginning after December 31, 2020, the annual limit of 80% on the amount of taxable income that NOLs generated in taxable years beginning after December 31, 2017 may offset. As a result of the anticipated NOL carryback claims for the Company's TRSs, total additional tax benefits of $1,172 have been recognized as part of other income and expense, net, on the consolidated statement of operations and comprehensive (loss) income for the year ended December 31, 2020. The Company has accrued no material interest or penalties relating to income taxes. As of December 31, 2020, the Company's 2019, 2018, and 2017 tax years remain subject to examination by U.S. and various state tax jurisdictions. Share-Based Compensation As of December 31, 2020, the Company has one share-based compensation plan under which time-based restricted stock units ("RSUs") and performance-based RSUs have been issued with tandem dividend equivalents. Compensation expense related to these awards, which are generally equity classified, and the tandem dividend equivalent cash payments are recognized as a part of general and administrative expenses on the consolidated statements of operations and comprehensive (loss) income. Time-based awards are generally measured at grant date fair value and not subsequently re-measured. Compensation expense related to these awards

Investment in Partially Owned Entities [Abstract]
Investment in Unconsolidated Entities	Investment in Unconsolidated Entities Joint Venture Interests IAGM As of December 31, 2020 and 2019, the Company owned a 55% interest in one unconsolidated entity, IAGM Retail Fund I, LLC ("IAGM"), a joint venture partnership between the Company and PGGM Private Real Estate Fund ("PGGM"). As of December 31, 2020 and 2019, the carrying value of the Company's investment in IAGM was $109,051 and $118,861, respectively. IAGM was formed on April 17, 2013 for the purpose of acquiring, owning, managing, supervising and disposing of retail properties and sharing in the profits and losses from those retail properties and their activities. The Company contributed 14 properties to IAGM during the year ended December 31, 2013, and treated the contributions as partial sales under FASB Topic 360-20, "Property, Plant and Equipment - Real Estate Sales." The resulting deferred aggregate gain of $15,625 was reflected as a basis adjustment and subsequently amortized over 30 years, consistent with the depreciation period of the investee's underlying assets. The Company's adoption of ASU No. 2017-05, Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets on January 1, 2018, resulted in the remaining $12,756 of the aforementioned deferred gain being recognized through beginning distributions in excess of accumulated net income. The Company analyzed the joint venture agreement and determined that IAGM was not a VIE. The Company also considered the joint venture partners' participating rights under the joint venture agreement and determined that the joint venture partners have the ability to participate in major decisions, which equates to shared decision making. Accordingly, the Company has significant influence but does not control IAGM. Therefore, IAGM was not consolidated by the Company, and the equity method of accounting was applied. Under the equity method of accounting, the net equity investment of the Company and the Company's share of net income or loss from the unconsolidated entity are reflected in the consolidated balance sheets and the consolidated statements of operations and comprehensive (loss) income. During the year ended December 31, 2020, the Company acquired Antoine Town Center from IAGM for $22,254, an estimated fair value determined by independent appraisal, which resulted in IAGM recognizing a gain on sale of $1,741. The Company deferred its share of IAGM's gain on sale of $958 and began amortizing the gain over 30 years as an increase to equity in earnings. Subsequent to purchasing Antoine Town Center, the Company completed a sale of an outparcel at this retail property to an unrelated third party which resulted in recognizing $54 of previously deferred gain. During the year ended December 31, 2020, IAGM recognized a provision for asset impairment of $11,015 on one retail property, of which the Company's share of this provision for asset impairment was $6,059, as disclosed in "Note 9. Fair Value Measurements" . During the year ended December 31, 2020, IAGM prepaid a $14,872 mortgage payable with cash on hand. During the year ended December 31, 2019, IAGM disposed of Rockwell Plaza, a 255,000 square foot retail property, for a gross disposition price of $20,500 and recognized a provision for asset impairment of $1,443 and a loss on sale of $559. The Company's share of IAGM's provision for asset impairment was $794, and its share of the loss on sale was $307. Proceeds from the sale were used to extinguish the related $16,250 non-recourse mortgage loan. During the year ended December 31, 2018, IAGM recognized a provision for asset impairment of $3,673 on three retail properties and a loss on sale of $4,135 on two retail properties. For the year ended December 31, 2018, the Company's share of IAGM's provision for asset impairment and loss on sale was $2,020 and $2,274, respectively. During the year ended December 31, 2020, IAGM entered into two interest rate swap agreements to achieve fixed interest rates on its senior secured term loan facility previously subject to variability in the London Inter-bank Offered Rate ("LIBOR"). Each of the interest rate swaps have an effective date of April 1, 2020 and a termination date of November 2, 2023. One interest rate swap has a notional amount of $45,000 and achieves a fixed interest rate of 1.979%. The other interest rate swap has a notional amount of $30,000 and achieves a fixed interest rate of 1.956%. The Company recognizes its share of gains or losses resulting from IAGM's interest rate swaps as an adjustment to the Company's investment in IAGM and an increase or decrease in comprehensive income. As of December 31, 2020, the interest rate swaps were recorded as a liability with a fair value of $525 on IAGM's consolidated balance sheet, of which the Company's share was $289. Downtown Railyard Ventures, LLC On September 30, 2015, the Company was admitted as a member to Downtown Railyard Venture, LLC ("DRV"), which was a joint venture established for the purpose of developing and selling a land development in Sacramento, California. During the year ended December 31, 2018, the Company recorded an other-than-temporary impairment of $29,933 on DRV due to a reduction in the expected hold period, thereby reducing the investment to an estimated fair value that the Company believed would be most probable of realization if the investment was liquidated. On June 24, 2019, the Company liquidated all interests in DRV in exchange for $30,000 of cash consideration. As a result of the other-than-temporary impairment recorded in 2018, the liquidation of interests resulted in no gain or loss being recognized in 2019. The Company has no continuing involvement with DRV. Condensed Financial Information The following table presents condensed balance sheet information for IAGM.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Recurring Measurements The following financial instruments are remeasured at fair value on a recurring basis: Fair Value Measurements as of Cash Flow Hedges: (a) December 31, 2020 December 31, 2019 Level 1 Level 2 Level 3 Level 1 Level 2 Level 3 Derivative interest rate assets (b) $ — $ — $ — $ — $ 1,057 $ — Derivative interest rate liabilities (c) — $ (12,449) — — — — (a) During the twelve months subsequent to December 31, 2020, an estimated $4,221 of derivative interest rate liabilities recognized in accumulated comprehensive (loss) income will be reclassified into earnings. (b) Recognized as a part of deferred costs and other assets, net, on the consolidated balance sheets. (c) Recognized as a part of other liabilities on the consolidated balance sheets. Level 1 At December 31, 2020 and 2019, the Company had no level one recurring fair value measurements. Level 2 To calculate the fair value of the derivative interest rate instruments, the Company primarily uses quoted prices for similar contracts and inputs based on data that are observed in the forward yield curve that is widely observable in the marketplace. The Company also incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements that utilize Level 3 inputs, such as estimates of current credit spreads. As of December 31, 2020 and 2019, the Company determined that the credit valuation adjustments associated with nonperformance risk are not significant to the overall valuation of its derivatives. As a result, the Company's derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy. Level 3 At December 31, 2020 and 2019, the Company had no level three recurring fair value measurements. Non-Recurring Measurements Investment Properties During the year ended December 31, 2020, the Company identified one retail property that had a reduction in its expected holding period and recorded a provision for asset impairment of $9,002 on the consolidated statement of operations and comprehensive (loss) income as a result of the fair value being lower than the property's carrying value. The Company's fair value was based on an executed sales contract. This property was disposed of on May 1, 2020. During the year ended December 31, 2019, the Company identified one retail property that had a reduction in its expected holding period and recorded a provision for asset impairment of $2,359 on the consolidated statement of operations and comprehensive (loss) income as a result of the fair value being lower than the property's carrying value. The Company's fair value was based on an executed sales contract. This property was disposed of on September 25, 2019. During the year ended December 31, 2018, the Company identified three retail properties that had reductions in the expected holding period and recorded an aggregate provision for asset impairment of $3,510 on the consolidated statement of operations and comprehensive (loss) income as a result of the fair values being lower than the properties' carrying values. The Company's fair values were based on executed sales contracts. Assets Held by Unconsolidated Entities During the year ended December 31, 2020, the Company identified one retail property within the IAGM joint venture that had a reduction in its expected holding period by the joint venture and recorded a provision for asset impairment of $11,015. A discounted cash flow model was utilized to estimate the fair value of this retail property. This cash flow model consisted of unobservable inputs such as forecasted revenues and expenses and estimated net disposition proceeds at the end of the hold period, based on market conditions and expected growth rates. A 8.50% terminal capitalization rate and a discount rate of 9.50% was utilized in the model based upon observable rates that the Company believed to be within a reasonable range of then current market rates, based on the nature of the underlying investment and associated risks. The Company recognized its' share of this provision for asset impairment of $6,059 on its consolidated statement of operations and comprehensive (loss) income as part of equity in (losses) earnings and (impairment), net, for the year ended December 31, 2020. Unconsolidated Entities During the year ended December 31, 2018, the Company evaluated its investment in DRV for potential other-than-temporary impairment due to a reduction in expected holding period. The Company obtained a third-party independent appraisal to assist in establishing a range of estimated fair values of the underlying assets as of December 31, 2018. The appraisal utilized a discounted cash flow model, which included inflows and outflows over a specific holding period. The cash flows consisted of unobservable inputs such as forecasted revenues and expenses, based on market conditions and expected growth rates. Capitalization rates ranging from 5.00% to 8.00% and discount rates ranging from 10.00% to 35.00% were utilized in the model based upon observable rates that the Company believed to be within a reasonable range of then current market rates, based on the nature of the underlying investment and associated risks. As a result of the third party independent appraisal, the Company recorded an other-than-temporary impairment of $29,933 related to DRV on the consolidated statement of operations and comprehensive (loss) income for the year ended December 31, 2018. The following table summarizes activity for the Company’s assets measured at fair value on a non-recurring basis and the related impairment charges for the years ended December 31, 2020, 2019, and 2018: December 31, 2020 December 31, 2019 December 31, 2018 Level 3 Impairment Loss Level 3 Impairment Loss Level 3 Impairment Loss Investment properties $ 5,500 $ 9,002 $ 42,250 $ 2,359 $ 64,075 $ 3,510 Investment in unconsolidated entities — — — — 30,049 29,933 Total $ 9,002 $ 2,359 $ 33,443 Financial Instruments Not Measured at Fair Value The table below represents the estimated fair value of financial instruments presented at carrying values in the Company's consolidated financial statements as of December 31, 2020 and 2019: December 31, 2020 December 31, 2019 Carrying Value Estimated Fair Value Carrying Value Estimated Fair Value Mortgages payable $ 107,261 $ 106,494 $ 176,051 $ 178,937 Term loans $ 400,000 $ 400,055 $ 400,000 $ 400,020 Revolving line of credit $ 50,000 $ 50,032 $ — $ — The Company estimated the fair value of its mortgages payable using a weighted-average effective market interest rate of 4.25% and 3.71% as of December 31, 2020 and 2019, respectively. The fair value estimate of the term loans approximate the carrying value due to limited market volatility in pricing. The assumptions reflect the terms currently available on similar borrowing terms to borrowers with credit profiles similar to that of the Company's. As a result, the Company used a weighted-average interest rate of 1.36% and 2.77% as of December 31, 2020 and 2019, respectively, to estimate the fair value of its term loans. The Company has determined that its debt instrument valuations are classified in Level 2 of the fair value hierarchy.

Earnings Per Share [Abstract]
Earnings Per Share and Equity Transactions	Earnings Per Share and Equity Transactions Basic earnings per share ("EPS") is computed using the two-class method by dividing net income by the weighted average number of common shares outstanding for the period (the "common shares") and participating securities. The restricted share awards issued pursuant to the InvenTrust Properties Corp. 2015 Incentive Award Plan (as amended, the "Incentive Award Plan") are deemed to be participating securities. Diluted EPS is generally computed using the treasury-stock method by dividing net income by the common shares plus potential common shares resulting from restricted share awards. The following table reconciles the amounts used in calculating basic and diluted earnings per share: Year ended December 31, 2020 2019 2018 Numerator: Net (loss) income from continuing operations $ (10,174) $ 63,899 $ 83,849 Earnings allocated to unvested restricted shares — (29) (95) Net (loss) income from continuing operations attributable to common shareholders $ (10,174) $ 63,870 $ 83,754 Net (loss) income from discontinued operations attributable to common shareholders $ — $ (25,500) $ — Denominator: Weighted average number of common shares outstanding - basic 719,882,476 728,620,309 761,139,011 Effect of unvested restricted shares (a) — 763,840 926,463 Weighted average number of common shares outstanding - diluted 719,882,476 729,384,149 762,065,474 Basic and diluted earnings per common share: Net (loss) income from continuing operations per share $ (0.01) $ 0.09 $ 0.11 Net loss from discontinued operations per share — (0.04) — Net (loss) income per share $ (0.01) $ 0.05 $ 0.11 (a) For the year ended December 31, 2020, the Company has excluded the anti-dilutive effect of unvested restricted shares. On November 1, 2019, the Company adopted a Second Amended and Restated Share Repurchase Program ("SRP"), authorizing redemption of the Company's shares of common stock, subject to certain conditions and limitations, to provide limited liquidity to stockholders. The Company's obligation to repurchase any shares under the SRP was conditioned upon having sufficient funds available to complete the repurchase. The repurchase price per share for all stockholders is equal to a 25% discount to the most recent estimated NAV per share of the Company's common stock established by the Company's board of directors, which was $3.14 per share as of May 1, 2019. During the year ended December 31, 2019, 8,517,605 shares were repurchased in connection with the SRP at a price per share of $2.355. During the year ended December 31, 2020, 2,136,119 shares were repurchased in connection with the SRP. On November 1, 2019, the Company began offering shares of the Company's common stock to existing stockholders pursuant to the Company's amended and restated distribution reinvestment plan ("DRP"). Under the DRP, stockholders may elect to reinvest an amount equal to the distributions declared on their shares of common stock into additional shares of the Company's common stock in lieu of receiving cash distributions. In accordance with the DRP, participants may acquire shares of common stock at a 25% discount to the most recent estimated NAV per share of the Company's common stock established by the Company's board of directors, which was $3.14 per share as of May 1, 2019. During the year ended December 31, 2019, the Company did not issue shares pursuant to the DRP. During the year ended December 31, 2020 the Company sold a total of 79,040 shares in connection with the DRP at a price per share of $2.355. Effective July 11, 2020, the Company suspended the SRP and the DRP. On August 15, 2018, the Company announced and commenced a modified "Dutch Auction" tender offer (the "Offer") to purchase for cash up to $75,000 in value of shares of the Company's common stock, par value $0.001 per share (the "Shares"), subject to its ability to increase the number of Shares accepted for payment by up to 2% of the Company's outstanding Shares. The Company exercised that option and increased the Offer by 10,706,774 shares, or $22,500, to avoid any proration for the stockholders tendering shares. The Offer expired on September 13, 2018. As a result of the Offer, the Company accepted for purchase 46,559,289 shares of its common stock (which represented approximately 6.0% of the shares of common stock outstanding at the time) at a purchase price of $2.10 per share, for a cost of approximately $97,775, excluding fees and expenses. Aggregate costs of $98,491 were recorded as reductions to common stock and additional paid-in capital on the consolidated statements of equity for the year ended December 31, 2018.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and ContingenciesThe Company is subject, from time to time, to various types of third-party legal claims or litigation that arise in the ordinary course of business, including, but not limited to, property loss claims, personal injury or other damages resulting from contact with the Company's properties. These claims and lawsuits and any resulting damages are generally covered by the Company's insurance policies. The Company accrues for legal costs associated with loss contingencies when these costs are probable and reasonably estimable. While the resolution of these matters cannot be predicted with certainty, based on currently available information, management does not expect that the final outcome of any pending claims or legal proceedings will have a material adverse effect on the financial condition, results of operations or cash flows of the Company. University House Communities Group, Inc., Indemnity Claims The Company received an indemnity notice from UHC Acquisition Sub LLC ("UHC") regarding certain matters under the Stock Purchase Agreement, dated January 3, 2016, for University House Communities Group, Inc., which was sold in June 2016. The notice set forth various items for which UHC believed they were entitled to indemnification from the Company. On June 14, 2019, UHC and the Company, through various negotiations, reached a final settlement for the claims in the amount of $30,000, which was paid by the Company on June 24, 2019. The Company recognized losses from discontinued operations related to these claims of $25,500 during the year ended December 31, 2019. Operating and Finance Lease Commitments The Company has non-cancelable contracts of property improvements that have been deemed to contain finance leases that, prior to the adoption of Topic 842, were previously classified as capital leases. In addition, the Company has non-cancelable operating leases for office space used in its business and, upon the adoption of Topic 842, the Company recognized operating lease right-of-use ("ROU") assets of $2,890 and lease liabilities of $3,114. In conjunction with the adoption of Topic 842, the Company elected the following practical expedients and accounting policies: • to combine lease and non-lease components and apply Topic 842 to the combined component; • to utilize a portfolio approach for determining a discount rate for groups of leases which are similar in nature and have similar contract provisions; • to not recognize assets and liabilities related to leases with terms of 12 months or less; and • to exclude variable lease payments from initial recognition of the lease liabilities and all lease options from the determination of minimum lease terms.

Basis of Presentation and Sum_2

Basis of Presentation and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2020
Accounting Policies [Abstract]
Reclassifications	Reclassifications The Company has made certain reclassifications to the consolidated statements of operations and comprehensive (loss) income for the years ended December 31, 2019 and 2018 to conform to the 2020 presentation, including amounts previously reported as realized and unrealized gains on marketable securities and income tax expense now reported as other income and expense, net.
Variable Interest Entities	Variable Interest Entities The Company evaluates its investments in LLCs and LPs to determine whether each such entity may be a variable interest entity ("VIE"). The accounting standards related to the consolidation of VIEs require qualitative assessments to determine whether the Company is the primary beneficiary. Determination of the primary beneficiary is based on whether the Company has (i) power to direct significant activities of the VIE and (ii) an obligation to absorb losses or the right to receive benefits that could be potentially significant to the VIE. The Company consolidates a VIE if it is deemed to be the primary beneficiary. The equity method of accounting is applied to entities in which the Company is not the primary beneficiary, or if the entity is not a VIE and the Company does not have control, but can exercise significant influence over the entity with respect to its operations and major decisions. As of December 31, 2020 and 2019, the Company had no VIEs.
Revenue Recognition	Revenue Recognition Adoption of Topic 842 In conjunction with the adoption of Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 842, Leases , ("Topic 842") on January 1, 2019, the Company elected the package of practical expedients which permitted the Company to not reassess: (1) whether any expired or existing contracts are, or contain leases; (2) the lease classification for any expired or existing leases; and (3) any initial direct costs for existing leases as of the effective date. Except as described below, the Company's accounting policies and resulting recognition of lease income remained substantially consistent with previous guidance. In addition, the Company has elected the practical expedient of not separating lease and non-lease components for all qualifying leases. In effect, this generally relieves the Company from the requirement to account for certain consideration under FASB ASC 606, Revenue from Contracts with Customers ("Topic 606"). As a result of the accounting policy election, all income arising from leases is presented on a combined basis as lease income, net on the consolidated statements of operations and comprehensive (loss) income. As a result of the narrowed definition of initial direct costs under Topic 842, the Company expenses as incurred certain lease origination costs previously capitalized and amortized to expense over the lease term. Lease Income The majority of revenue recognized from the Company's retail properties is comprised of fixed and variable consideration received from tenants under long-term operating leases with varying terms. Fixed consideration generally consists of minimum lease payments for the rental of retail space while the variable consideration generally consists of reimbursements of the tenant's pro-rata share of certain operating expenses incurred by the Company, including real estate taxes, special assessments, insurance, utilities, common area maintenance, management fees and certain capital repairs. Certain other tenants are subject to net leases whereby the tenant is responsible for fixed minimum lease payments to the Company, as well as directly paying all costs and expenses associated with occupancy to third party service providers. Such direct payments to third parties are not recorded as revenue and expense by the Company. Minimum lease payments are recognized on a straight-line basis over the term of each lease. The cumulative difference between fixed consideration recognized on a straight-line basis and the cash payments due under the provisions of the lease agreements is recorded as deferred rent receivable and is included as a component of accounts and rents receivable on the consolidated balance sheets. The Company records lease termination income when all conditions of a signed termination agreement have been met, the tenant is no longer occupying the property, and termination income amounts due are considered collectible. The Company defers recognition of contingent lease income until the specified target that triggers the contingent lease income is achieved. The Company commences revenue recognition on its leases when the lessee takes possession of, or controls the physical use of, the leased asset, unless the lessee is constructing improvements for which the Company is deemed to be the owner for accounting purposes. If the Company is deemed the owner for accounting purposes, the leased asset is the finished space and revenue recognition commences when the lessee takes possession of it, typically when the improvements are substantially complete. Alternatively, if the lessee is deemed to be the owner of the improvements for accounting purposes, then the leased asset is the unimproved space, and any tenant improvement allowances funded under the lease are treated as lease incentives, which reduce lease income recognized over the lease term, and the Company commences revenue recognition when the lessee takes possession of the unimproved space. The determination of who owns the tenant improvements, for accounting purposes, is based on contractual rights and subject to judgment. In making that judgment, no one factor is determinative. The Company routinely considers: • whether the lease stipulates how and on what a tenant improvement allowance may be spent; • whether the tenant is required to provide evidence supporting the cost of improvements prior to reimbursement; • whether the tenant or landlord retains legal title to the improvements; • the uniqueness of the improvements; • the expected economic life of the tenant improvements relative to the length of the lease; and • who constructs or directs the construction of the improvements. Staff Q&A, Topic 842 and Topic 840: Accounting for Lease Concessions Related to the Effects of the COVID-19 Pandemic In April 2020, the FASB issued a document titled Staff Q&A, Topic 842 and Topic 840: Accounting for Lease Concessions Related to the Effects of the COVID-19 Pandemic ("FASB Q&A document"). The FASB Q&A document permits an election whereby an entity is not required to evaluate whether certain relief provided by a lessor in response to the COVID-19 pandemic is a lease modification (the "COVID-19 election"). An entity that makes this election can then either apply the modification guidance to that relief or account for the concession as if it were contemplated as part of the existing contract. This election is available for concessions related to the effects of the COVID-19 pandemic that do not result in a substantial increase in the rights of the lessor or the obligations of the lessee. In response to receiving numerous rent relief requests, the Company has adopted the COVID-19 election, under which lease amendments providing tenants with COVID-19 related rent relief are not treated as lease modifications unless: • the total payments required by the amended lease are not substantially equal to or less than the total payments required by the original lease; or • the amended lease results in an increase to the lease term. Rent relief has most frequently been requested in the form of deferral of rental payments. A deferral affects the timing of cash receipts, but the amount of consideration is substantially the same as that required by the original lease. Under the Company's COVID-19 election, deferrals are accounted for as if no changes to the lease contract were made. The Company continues to recognize rental income and increase lease receivables during the deferral period. Rent abatements or other reductions in total payments are treated as negative variable rent in the period to which the rent relates. Credit Losses The Company reviews the collectability of amounts due from its tenants on a regular basis. Such reviews consider the tenant's financial condition and payment history and other economic conditions impacting the tenant. Changes in collectability occur when the Company no longer believes it is probable that substantially all the lease payments will be collected over the term of the lease. If collection is not probable, regardless of whether the Company has entered into an amendment to provide the tenant with COVID-19 related rent relief, the lease payments will be accounted for on a cash basis, and revenue will be recorded as cash is received. If reassessed, and the collection of substantially all of the lease payments from the tenant becomes probable, the accrual basis of revenue recognition is reestablished. Beginning on January 1, 2019, the provision for estimated credit losses resulting from changes in the expected collectability of lease payments, including variable payments, is recognized as a direct adjustment to lease income on the consolidated statements of operations and comprehensive (loss) income, and a direct write-off of the operating lease receivables, including straight-line rent receivable, on the consolidated balance sheets. The Company continues to evaluate the impact of the COVID-19 pandemic on its ability to collect future lease payments under the terms of the respective leases. As the duration and severity of the COVID-19 pandemic are still uncertain and continue to evolve, uncertainty exists regarding the Company's provision for estimated credit losses for deferred rental payments receivable, billed rent and straight-line rent receivables. Other Fee Income The Company recognizes other fee income when it satisfies a performance obligation relating to services provided to its joint venture partnership. The resulting receivables are settled through recurring monthly payments for the services provided over the term of the contract. The Company generally does not receive prepayments for services or recognize revenue prior to being legally entitled to payment. As a result, the Company does not generally record contract assets or contract liabilities. Property management and asset management fees are recognized over time as services are rendered to the joint venture partnership. The bundled services of the property management performance obligation and asset management performance obligation each qualify as a series of distinct services satisfied over time. The variable consideration related to each of the performance obligations is recognized in each of the periods that directly relate to the Company's efforts to provide those services. Accordingly, the Company elected the optional exemption provided by Topic 606 to not disclose information about remaining wholly unsatisfied performance obligations. The variability in timing of the property management and asset management fees, which generally relate to the fluctuation in cash receipts from tenants and potential changes in equity capitalization, are resolved on a monthly basis. For certain services, the Company acts as an agent on behalf of the customer to arrange for performance by a third party. Based on the Company's judgment, both the underlying asset management service activities and the underlying property management service activities are not distinct but are inputs (or fulfillment activities) to provide the combined output (either the overall asset management service or the overall property management service). Leasing commissions and other fees are recognized at a point in time consistent with the underlying service rendered to the joint venture partnership. The leasing performance obligation and other performance obligations are satisfied at the point in which the customer is transferred control over and consumes the benefit of the service. The uncertainty of the leasing commissions and other fees are resolved upon delivery of the underlying service. Generally, the first and second installments of leasing commissions are paid upon lease execution and rent commencement, respectively. Sale of Real Estate
Acquisition of Real Estate	Acquisition of Real Estate The Company evaluates the inputs, processes and outputs of each asset acquired to determine if the transaction is a business combination or asset acquisition. If an acquisition qualifies as a business combination, the related transaction costs are recorded as an expense in the consolidated statements of operations and comprehensive (loss) income. If an acquisition qualifies as an asset acquisition, the related transaction costs are generally capitalized and amortized over the useful life of the acquired assets. Generally, acquisition of real estate qualifies as an asset acquisition. The Company allocates the purchase price of real estate to land, building, other building improvements, tenant improvements, intangible assets and liabilities (such as the value of above- and below-market leases, in-place leases and origination costs associated with in-place leases). The values of above- and below-market leases are recorded as intangible assets, net, and intangible liabilities, net, respectively, on the consolidated balance sheets, and are amortized as either a decrease (in the case of above-market leases) or an increase (in the case of below-market leases) to lease income over the remaining term of the associated tenant lease. The values, if any, associated with in-place leases are recorded in intangible assets, net, on the consolidated balance sheets and are amortized to depreciation and amortization expense on the consolidated statements of operations and comprehensive (loss) income over the remaining lease term. The difference between the contractual rental rates and the Company's estimate of market rental rates is measured over a period equal to the remaining non-cancelable term of the leases plus the term of any below-market renewal options. For the amortization period, the remaining term of leases with renewal options at terms below market reflect the assumed exercise of such below-market renewal options, if reasonably assured. If a tenant vacates its space prior to the contractual expiration of the lease and no rental payments are being made on the lease, any unamortized balance of the related intangible asset or liability is written off. Tenant improvements are depreciated and origination costs are amortized over the remaining term of the lease or charged against earnings if the lease is terminated prior to its contractual expiration date. The Company performs, with the assistance of a third-party valuation specialist, the following procedures for assets acquired: • Estimate the value of the property "as if vacant" as of the acquisition date; • Allocate the value of the property among land, building, and other building improvements and determine the associated useful life for each; • Calculate the value and associated life of above- and below-market leases on a tenant-by-tenant basis. The difference between the contractual rental rates and the Company’s estimate of market rental rates is measured over a period equal to the remaining term of the leases (using a discount rate which reflects the risks associated with the leases acquired, including geographical location, size of leased area, tenant profile and credit risk); • Estimate the fair value of the tenant improvements, legal costs and leasing commissions incurred to obtain the leases and calculate the associated useful life for each; • Estimate the fair value of assumed debt, if any; and
Properties Held for Sale	Properties Held for Sale In determining whether to classify a property as held for sale, the Company considers whether: (i) management has committed to a plan to sell the property; (ii) the property is available for immediate sale, in its present condition; (iii) the Company has initiated a program to locate a buyer; (iv) the Company believes that the sale of the property is probable; (v) the Company has received a significant non-refundable deposit for the purchase of the property; (vi) the Company is actively marketing the property for sale at a price that is reasonable in relation to its estimated fair value; and (vii) actions required for the Company to complete the plan indicate that it is unlikely that any significant changes will be made to the plan. When all criteria are met, the property is classified as held for sale and carried at the lower of cost or estimated fair value less costs to sell. Additionally, if the sale represents a strategic shift that has (or will have) a major effect on the Company's results and operations, the income and expenses for the period are classified as discontinued operations on the consolidated statements of operations and comprehensive (loss) income for all periods presented.
Impairment of Long Lived Assets	Impairment of Long Lived Assets The Company assesses the carrying values of long-lived tangible and intangible assets whenever events or changes in circumstances indicate that the carrying amounts of these assets may not be fully recoverable, such as a reduction in the expected holding period of a property. If it is determined that the carrying value is not recoverable because the expected undiscounted cash flows do not exceed that carrying value, the Company records an impairment loss to the extent that the carrying value exceeds the estimated fair value. The valuation and possible subsequent impairment of investment properties is a significant estimate that can and does change based on the Company's continuous process of analyzing each property's economic condition at a point in time and reviewing assumptions about uncertain inherent factors, including observable inputs such as contractual revenues and unobservable inputs such as forecasted revenues and expenses, estimated net disposition proceeds, and discount rate. These unobservable inputs are based on a property's market conditions and expected growth rates. However, assumptions and estimates about future cash flows and capitalization rates are complex and subjective. Changes in economic and operating conditions and the Company's ultimate investment intent that occur subsequent to the impairment analyses could impact these assumptions and result in additional impairment of the investment properties. Periodically, management assesses whether there are any indicators that the carrying value of the Company's investments in unconsolidated entities may be other-than-temporarily impaired. To the extent other-than-temporary impairment has occurred, the loss is measured as the excess of the carrying value of the investment over the estimated fair value of the investment. The estimated fair value of the investment is generally derived from the cash flows generated from the underlying real property investments of the investee.
Real Estate Capitalization and Depreciation	Real Estate Capitalization and Depreciation Real estate is reflected at cost less accumulated depreciation within investment properties on the consolidated balance sheets. Ordinary repairs and maintenance are expensed as incurred. Depreciation expense is computed using the straight-line method. A range of estimated useful lives of 15-30 years is used for buildings and other improvements, and a range of 5-20 years is used for furniture, fixtures and equipment. Finance lease asset amortization is computed using the straight-line method over the lease term and included in depreciation and amortization on the consolidated statements of operations and comprehensive (loss) income. Tenant improvements not of use to subsequent tenants are amortized on a straight-line basis over the lesser of the life of the tenant improvement or the lease term. Amortization is included in depreciation and amortization on the consolidated statements of operations and comprehensive (loss) income. Deferred leasing costs are recognized as a part of deferred costs and other assets, net, on the consolidated balance sheets and are amortized to depreciation and amortization on the consolidated statements of operations and comprehensive (loss) income over the remaining term of the associated tenant lease. Direct and indirect costs that are clearly related to the construction and improvements of investment properties are capitalized. Costs incurred for interest, property taxes and insurance are capitalized during periods in which activities necessary to prepare the property for its intended use are in progress.
Cash and Cash Equivalents and Restricted Cash	Cash and Cash Equivalents The Company considers all demand deposits, money market accounts and investments in certificates of deposit and repurchase agreements with a maturity of three months or less, at the date of purchase, to be cash equivalents. The Company maintains its cash and cash equivalents at financial institutions. The combined account balances at one or more institutions generally exceed the Federal Deposit Insurance Corporation ("FDIC") insurance coverage. The Company periodically assesses the credit risk associated with these financial institutions. There is what the Company believes to be insignificant credit risk related to amounts on deposit in excess of FDIC insurance coverage. Restricted Cash Restricted cash consists of lenders’ escrows, operating real estate escrows for taxes, insurance, capital expenditures and payments required under certain lease agreements, and funds restricted through lender or other agreements, including funds held in escrow for future acquisitions.
Derivative Instruments	Derivative Instruments In the normal course of business, the Company is exposed to the effect of interest rate changes. The Company's objective in using interest rate derivatives is to manage its exposure to interest rate movements and add stability to interest expense. To accomplish this objective, the Company uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable rate amounts from a counterparty in exchange for the Company making fixed rate payments over the life of the agreement without exchange of the underlying notional amount. The Company has a policy of only entering into contracts with established financial institutions based upon their credit ratings and other factors. When viewed in conjunction with the underlying and offsetting exposure that the derivatives are designed to hedge, the Company has not sustained a material loss from those instruments, nor does it anticipate any material adverse effect on its net income or financial position in the future from the use of derivatives. The Company recognizes all derivatives on the consolidated balance sheets at fair value. Additionally, the fair value adjustments will affect either equity or net income depending on whether the derivative instruments qualify as a hedge for accounting purposes and, if so, the nature of the hedging activity. When the underlying transaction is terminated or completed, all changes in the fair value of the instrument are marked-to-market with changes in value included in net income each period until the instrument matures. Any derivative instrument used for risk management that does not meet the criteria for hedge accounting is marked-to-market each period on the consolidated statements of operations and comprehensive (loss) income. The Company does not use derivatives for trading or speculative purposes.
Fair Value Measurements	Fair Value Measurements In accordance with FASB ASC 820, Fair Value Measurement and Disclosures ("Topic 820"), the Company defines fair value based on the price that would be received upon sale of an asset or the exit price that would be paid to transfer or settle a liability in an orderly transaction between market participants at the measurement date. The Company uses a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value. The fair value hierarchy consists of the three broad levels described below: • Level 1 - Quoted prices in active markets for identical assets or liabilities that the entity has the ability to access. • Level 2 - Observable inputs, other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. • Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs. The Company has estimated the fair value of its financial instruments and non-financial assets using available market information and valuation methodologies the Company believes to be appropriate for these purposes. Considerable judgment and a high degree of subjectivity are involved in developing these estimates and, accordingly, they are not necessarily indicative of amounts that would be realized upon disposition. The carrying amounts of cash and cash equivalents, restricted cash, accounts and rents receivables, other assets, accounts payable, accrued expenses and other liabilities reasonably approximate fair value, in management’s judgment, because of their short-term nature. Fair value information pertaining to derivative financial instruments, investment properties, investments in unconsolidated entities and debt is provided in "Note 9. Fair Value Measurements" .
Income Taxes	Income Taxes The Company is qualified and has elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the "Code") for federal income tax purposes commencing with the tax year ended December 31, 2005. Since the Company qualifies for taxation as a REIT, the Company generally is not subject to federal income tax on taxable income distributed to stockholders. To continue to qualify as a REIT, the Company generally is required to distribute at least 90% of its REIT taxable income (subject to certain adjustments) to its stockholders each year (the "90% Distribution Requirement"). If the Company fails to qualify as a REIT in any taxable year, without the benefit of certain relief provisions, the Company will be subject to federal and state income tax on its taxable income at regular corporate tax rates. Even if the Company qualifies for taxation as a REIT, the Company may be subject to certain state and local taxes on its income, property or net worth and federal income and excise taxes on its undistributed income. From time to time, the Company may elect to treat certain of its consolidated subsidiaries as taxable REIT subsidiaries ("TRSs") pursuant to the Code. Among other activities, TRSs may participate in non-real estate related activities and/or perform non-customary services for tenants and are subject to federal and state income tax at regular corporate tax rates. During 2020, the Company either revoked the TRS elections or dissolved the legal entities for any of its consolidated subsidiaries that were TRSs. The Company accounts for income taxes using the asset and liability method under which deferred tax assets and liabilities are recognized for the estimated future tax consequences attributed to differences between the GAAP carrying amounts of existing assets and liabilities and their respective tax bases. In assessing the realizability of the resulting deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. As of December 31, 2019, Management determined it was more likely than not that the Company would not have realized $26,427 of benefits relating to deductible differences. Accordingly, a valuation allowance was recognized to reduce the deferred tax assets to zero. At the time of revocation or liquidation in 2020, the TRSs had approximately $26,153 of gross deferred tax asset and a corresponding valuation allowance of $26,153. As a result, both the gross deferred tax asset and valuation allowance were reversed resulting in a net zero impact to both the net deferred tax asset and income tax expense. As of December 31, 2020, the Company has no significant deferred tax assets/liabilities. Income tax expense for the years ended December 31, 2020, 2019 and 2018 is generally comprised of federal and state taxes paid by consolidated TRSs and certain state taxes paid by the Company. Under the federal legislation enacted on March 27, 2020, known as the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act"), certain limitations on the deductibility of net operating losses ("NOLs") enacted under prior federal tax legislation have been temporarily rolled back. In particular, the CARES Act permits businesses to carryback NOLs generated in taxable years beginning after December 31, 2017 and before January 1, 2021 to the previous five years and temporarily suspends, until taxable years beginning after December 31, 2020, the annual limit of 80% on the amount of taxable income that NOLs generated in taxable years beginning after December 31, 2017 may offset. As a result of the anticipated NOL carryback claims for the Company's TRSs, total additional tax benefits of $1,172 have been recognized as part of other income and expense, net, on the consolidated statement of operations and comprehensive (loss) income for the year ended December 31, 2020.
Share Based Compensation	Share-Based Compensation As of December 31, 2020, the Company has one share-based compensation plan under which time-based restricted stock units ("RSUs") and performance-based RSUs have been issued with tandem dividend equivalents. Compensation expense related to these awards, which are generally equity classified, and the tandem dividend equivalent cash payments are recognized as a part of general and administrative expenses on the consolidated statements of operations and comprehensive (loss) income. Time-based awards are generally measured at grant date fair value and not subsequently re-measured. Compensation expense related to these awards is recognized on a straight-line basis over the vesting period. Performance-based awards are measured at grant date fair value and each grantee is eligible to vest in a number of RSUs ranging from 0% to 100% of the total number granted based on specified performance levels. For awards with a performance condition, compensation cost is recognized when the performance condition is considered probable of achievement. If a performance award has more than one potential outcome, recognition of compensation cost is based on the most likely outcome. During the service period, a cumulative catch-up approach is used to account for changes in the assessment of which outcome is most likely to occur. Absent a change in the determination of the most likely outcome, compensation expense related to these awards would be recognized on a straight-line basis from the grant date through the vesting date. Forfeitures of awards are recognized as they occur.
