Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying Consolidated Financial Statements include the financial position and results of operations of the Company, the Operating Partnership and its wholly owned subsidiaries. The Company consolidates the Operating Partnership, a VIE in which the Company is considered the primary beneficiary. The primary beneficiary is the entity that has (i) the power to direct the activities that most significantly impact the entity’s economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could be significant to the VIE. A non-controlling interest is defined as the portion of the equity in an entity not attributable, directly or indirectly, to the Company. Non-controlling interests are required to be presented as a separate component of equity in the Consolidated Balance Sheets. Accordingly, the presentation of net income reflects the income attributed to controlling and non-controlling interests. The accompanying Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. This interim financial information should be read in conjunction with the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021. Management believes that all adjustments of a normal, recurring nature considered necessary for a fair presentation have been included. This interim financial information does not necessarily represent or indicate what the operating results will be for the year ending December 31, 2022. All material intercompany accounts and transactions have been eliminated.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses during the reporting period. Although management believes its estimates are reasonable, actual results could differ from those estimates.
Offering and Other Costs	Offering and Other Costs Offering costs are recorded in “Total Stockholders’ Equity” in the Consolidated Balance Sheets as a reduction of additional paid-in capital.
Deferred Costs	Deferred Costs Financing costs related to the issuance of the Company’s long-term debt, including the term loan facility component of the Company's existing credit facilities (the "Credit Facilities"), are deferred and amortized as an increase to interest expense over the term of the related debt instrument using the straight-line method, which approximates the effective-interest rate method, and are reported as a reduction of the related debt balance on the Consolidated Balance Sheets. Deferred financing costs related to the revolving credit facility component (the "2021 Revolving Credit Facility") of the Credit Facilities are deferred and amortized as an increase to interest expense over the terms of the 2021 Revolving Credit Facility and are included in “Prepaid expenses and other assets, net” on the Consolidated Balance Sheets.
Reclassifications	Reclassifications Certain prior period amounts have been reclassified to conform to the current period’s presentation.
Cash and Escrows and Reserves	Cash and Escrows and ReservesCash includes unrestricted cash with a maturity of three months or less. Escrows and reserves consist of restricted cash.
Revenue Recognition	Revenue Recognition The Company has operating lease agreements with tenants, some of which contain provisions for future rental increases. Rental income is recognized on a straight-line basis over the term of the lease. In addition, certain lease agreements provide for reimbursements from tenants for real estate taxes and other recoverable costs, which are recorded on an accrual basis as part of “Rental income” in the Consolidated Statements of Operations and Comprehensive Income. Fee and other primarily consists of (i) property management fees, (ii) income recognized from properties accounted for as financing leases and (iii) fees earned from providing advisory services to third-party owners of postal properties. The management fees arise from contractual agreements with entities that are affiliated with the Company’s CEO. Management fee income is recognized as earned under the respective agreements. Revenue from direct financing leases is recognized over the lease term using the effective interest rate method. At lease inception, the Company records an asset within "Investments in financing leases, net" on the Consolidated Balance Sheets, which represents the Company’s net investment in the direct financing leases. This initial net investment is determined by aggregating the total future minimum lease payments attributable to the direct financing leases and the estimated residual value of the property, if any, less unearned income. Over the lease term, the investment in the direct financing leases is reduced and income is recognized as revenue in “Fee and other” in the Consolidated Statements of Operations and Comprehensive Income and produces a constant periodic rate of return on the investment in financing leases, net. Revenue from advisory services is generated from service contracts generally based on (i) time and expense arrangements (where the Company recognizes revenues based on hours incurred and contracted rates), (ii) fixed-fee arrangements (where the Company recognizes revenues earned to date by applying the proportional performance method) or (iii) performance-based or contingent arrangements (where the Company recognizes revenues at a point in time when the client receives the benefit of the promised service). Reimbursable expenses for the advisory services, including those relating to travel, out-of-pocket expenses, outside consultants and other outside service costs, are generally included in revenues and in general and administrative expenses in the period in which the expense is incurred.
Business Combinations, Goodwill And Intangible Assets	Business Combinations, Goodwill and Intangible Assets The Company accounts for business combinations using the acquisition method, which requires the identification of the acquirer, the determination of the acquisition date and the allocation of the purchase price paid by the acquirer to the identifiable tangible and intangible assets acquired, the liabilities assumed, including any contingent consideration and any non-controlling interest in the acquiree at their acquisition date fair values. Goodwill represents the excess of the purchase price over the fair value of net assets acquired, including the amount assigned to identifiable intangible assets. Intangible assets may include customer relationships, trademarks and acquired software. Identifiable intangible assets with finite lives are amortized over their expected useful lives. Acquisition-related costs are expensed in the periods in which the costs are incurred. The results of operations of acquired businesses are included in the Company’s Consolidated Financial Statements from the acquisition date. The Company evaluates goodwill for impairment at least annually, or as circumstances warrant. Goodwill is evaluated at the reporting unit level by comparing the fair value of the reporting unit with its carrying amount including goodwill. An impairment of goodwill exists if the carrying amount of the reporting unit exceeds its fair value. The impairment loss is the amount by which the carrying amount exceeds the reporting unit’s fair value, limited to the total amount of goodwill allocated to that reporting unit. Intangible assets with finite lives are amortized over their estimated useful lives and reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If an impairment indicator is present, the Company evaluates recoverability of assets to be held and used by a comparison of the carrying value of the assets with future undiscounted net cash flows expected to be generated by the assets. The Company groups assets at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows generated by other asset groups. If the total of the expected undiscounted future cash flows is less than the carrying amount of the asset group, the Company estimates the fair value of the asset group to determine whether an impairment loss should be recognized.
Fair Value of Financial Instruments	Fair Value Measurements The following disclosure of estimated fair value was determined by management using available market information and appropriate valuation methodologies. However, considerable judgment is necessary to interpret market data and develop estimated fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could have realized on disposition of the assets and liabilities as of September 30, 2022 and December 31, 2021. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. Cash, escrows and reserves, receivables, prepaid expenses and other assets (excluding derivatives), accounts payable and accrued expenses are carried at amounts which reasonably approximate their fair values as of September 30, 2022 and December 31, 2021 due to their short maturities. The fair value of the Company’s borrowings under its Credit Facilities approximates carrying value because such borrowings are subject to a variable rate which reprices frequently. The fair value of the Company’s secured borrowings aggregated approximately $27.4 million and $32.1 million as compared to the principal balance of $33.1 million and $33.2 million as of September 30, 2022 and December 31, 2021, respectively. The fair value of the Company’s debt was categorized as a Level 3 basis (as provided by ASC 820, Fair Value Measurements and Disclosures). The fair value of these financial instruments was determined by using a discounted cash flow analysis based on the borrowing rates currently available to the Company for loans with similar terms and maturities. The fair value of the mortgage debt was determined by discounting the future contractual interest and principal payments by a market rate. The Company's derivative assets and liabilities, comprised of interest rate swap derivative instruments entered into in connection with the Credit Facilities, are recorded at fair value based on a variety of observable inputs, including contractual terms, interest rate curves, yield curves, measure of volatility, and correlations of such inputs. The Company measures its derivatives at fair value on a recurring basis based on the expected size of future cash flows on a discounted basis and incorporating a measure of non-performance risk. The fair value of the Company's derivative assets and liabilities was categorized as a Level 2 basis (as provided by ASC 820, Fair Value Measurements and Disclosures). The Company considers its own credit risk, as well as the credit risk of its counterparties, when evaluating the fair value of its derivative assets and liabilities. As of September 30, 2022 and December 31, 2021, the fair value of the Company’s interest rate swap derivative assets was approximately $9.3 million and $1.0 million, respectively, included in “Prepaid expenses and other assets, net” on the Consolidated Balance Sheet. Disclosure about fair value of assets and liabilities is based on pertinent information available to management as of September 30, 2022 and December 31, 2021. Although management is not aware of any factors that would significantly affect the fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since September 30, 2022 and current estimates of fair value may differ significantly from the amounts presented herein.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities In accordance with ASC 815, Derivatives and Hedging, the Company records all derivative instruments on the Consolidated Balance Sheets at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, 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 variability in expected future cash flows 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 of its risks, even though hedge accounting does not apply or the Company elects not to apply hedge accounting.
Impairment	Impairment The carrying value of real estate investments and related intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment exists when the carrying amount of an asset exceeds the aggregate projected future cash flows over the anticipated holding period on an undiscounted basis. An impairment loss is measured based on the excess of the asset’s carrying amount over its estimated fair value. Impairment analyses will be based on current plans, intended holding periods and available market information at the time the analyses are prepared. If estimates of the projected future cash flows, anticipated holding periods or market conditions change, the evaluation of impairment losses may be different and such differences may be material. The evaluation of anticipated cash flows is subjective and is based, in part, on assumptions regarding future occupancy, rental rates and capital requirements that could differ materially from actual results.
Concentration of Credit Risks	Concentration of Credit Risks As of September 30, 2022, the Company’s properties were leased primarily to a single tenant, the USPS. For the nine months ended September 30, 2022, 15.4% of the Company’s total rental income, or $5.6 million, was concentrated in Pennsylvania. For the nine months ended September 30, 2021, 18.3% of the Company's total rental income, or $5.1 million, was concentrated in Pennsylvania. The ability of the USPS to honor the terms of its leases is dependent upon regulatory, economic, environmental or competitive conditions in Pennsylvania or other regions where the Company operates in and could have a material effect on the Company’s overall business results. The Company has deposited cash and maintains its bank deposits with large financial institutions in amounts that, from time to time, exceed federally insured limits. The Company has not experienced any losses in such accounts.
Equity Based Compensation	Equity Based Compensation The Company accounts for equity-based compensation in accordance with ASC Topic 718 Compensation – Stock Compensation, which requires the Company to recognize an expense for the grant date fair value of equity-based awards. Equity-classified stock awards granted to employees and non-employees that have a service condition and/or a market condition are measured at fair value at date of grant and remeasured at fair value only upon a modification of the award. The Company records forfeitures as they occur. The Company recognizes compensation expense on a straight-line basis over the requisite service period of each award, with the amount of compensation expense recognized at the end of a reporting period at least equal the portion of fair value of the respective award at grant date or modification date, as applicable, that has vested through that date. For awards with a market condition, compensation cost is not reversed if a market condition is not met so long as the requisite service has been rendered, as a market condition does not represent a vesting condition.
Insurance Accounting	Insurance Accounting The Company carries liability insurance to mitigate its exposure to certain losses, including those relating to property damage and business interruption. The Company records the estimated amount of expected insurance proceeds for property damage and other losses incurred as an asset (typically a receivable from the insurer) and income up to the amount of the losses incurred when the amount is determinable and approved by the insurance company. Any amount of insurance recovery in excess of the amount of the losses incurred is considered a gain contingency and is not recorded in other income until the amount is determinable and approved by the insurance company. Insurance recoveries for business interruption for lost revenue or profit are accounted for as gain contingencies in their entirety, and therefore are not recorded in income until the amount is determinable and approved by the insurance company.
Earnings per Share	Earnings per Share The Company calculates earnings per share ("EPS") based upon the weighted average shares outstanding less issued and outstanding non-vested shares of Class A common stock. As of September 30, 2022 and 2021, the Company had unvested restricted shares of Class A common stock, long term incentive units of the Operating Partnership ("LTIP Units") and certain restricted stock units (“RSUs”), which provide for non-forfeitable rights to dividend and dividend equivalent payments. Accordingly, these unvested restricted shares of Class A common stock, LTIP Units and RSUs are considered participating securities and are included in the computation of basic and diluted EPS pursuant to the two-class method. Diluted EPS is calculated after giving effect to all potential dilutive shares outstanding during the period. See Note 10. Earnings Per Share for further details.
Recently Adopted and Future Application of Accounting Pronouncements	Future Application of Accounting Standards In September 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and in November 2018 issued ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments - Credit Losses. The guidance changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The guidance replaces the current "incurred loss" model with an "expected loss" approach. The Company will also be required to disclose information about how it developed the allowances, including changes in the factors that influenced the Company’s estimate of expected credit losses and the reasons for those changes. ASU No. 2018-19 excludes operating lease receivables from the scope of this guidance. This guidance will be effective for the Company on January 1, 2023, as a result of its classification as an EGC. The Company is currently in the process of evaluating the impact the adoption of the guidance will have on its consolidated financial statements.

9 Months Ended

Sep. 30, 2022

The accompanying Consolidated Financial Statements include the financial position and results of operations of the Company, the Operating Partnership and its wholly owned subsidiaries.

The Company consolidates the Operating Partnership, a VIE in which the Company is considered the primary beneficiary. The primary beneficiary is the entity that has (i) the power to direct the activities that most significantly impact the entity’s economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could be significant to the VIE.

A non-controlling interest is defined as the portion of the equity in an entity not attributable, directly or indirectly, to the Company. Non-controlling interests are required to be presented as a separate component of equity in the Consolidated

Balance Sheets. Accordingly, the presentation of net income reflects the income attributed to controlling and non-controlling interests.

The accompanying Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements.

This interim financial information should be read in conjunction with the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021. Management believes that all adjustments of a normal, recurring nature considered necessary for a fair presentation have been included. This interim financial information does not necessarily represent or indicate what the operating results will be for the year ending December 31, 2022. All material intercompany accounts and transactions have been eliminated.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses during the reporting period. Although management believes its estimates are reasonable, actual results could differ from those estimates.

Offering and Other Costs

Offering costs are recorded in “Total Stockholders’ Equity” in the Consolidated Balance Sheets as a reduction of additional paid-in capital.

Deferred Costs

Financing costs related to the issuance of the Company’s long-term debt, including the term loan facility component of the Company's existing credit facilities (the "Credit Facilities"), are deferred and amortized as an increase to interest expense over the term of the related debt instrument using the straight-line method, which approximates the effective-interest rate method, and are reported as a reduction of the related debt balance on the Consolidated Balance Sheets. Deferred financing costs related to the revolving credit facility component (the "2021 Revolving Credit Facility") of the Credit Facilities are deferred and amortized as an increase to interest expense over the terms of the 2021 Revolving Credit Facility and are included in “Prepaid expenses and other assets, net” on the Consolidated Balance Sheets.

Reclassifications

Certain prior period amounts have been reclassified to conform to the current period’s presentation.

Cash and Escrows and Reserves

Cash and Escrows and ReservesCash includes unrestricted cash with a maturity of three months or less. Escrows and reserves consist of restricted cash.

Revenue Recognition

The Company has operating lease agreements with tenants, some of which contain provisions for future rental increases. Rental income is recognized on a straight-line basis over the term of the lease. In addition, certain lease agreements provide for reimbursements from tenants for real estate taxes and other recoverable costs, which are recorded on an accrual basis as part of “Rental income” in the Consolidated Statements of Operations and Comprehensive Income.

Fee and other primarily consists of (i) property management fees, (ii) income recognized from properties accounted for as financing leases and (iii) fees earned from providing advisory services to third-party owners of postal properties.

The management fees arise from contractual agreements with entities that are affiliated with the Company’s CEO. Management fee income is recognized as earned under the respective agreements.

Revenue from direct financing leases is recognized over the lease term using the effective interest rate method. At lease inception, the Company records an asset within "Investments in financing leases, net" on the Consolidated Balance Sheets, which represents the Company’s net investment in the direct financing leases. This initial net investment is determined by aggregating the total future minimum lease payments attributable to the direct financing leases and the estimated residual value of the property, if any, less unearned income. Over the lease term, the investment in the direct financing leases is reduced and income is recognized as revenue in “Fee and other” in the Consolidated Statements of Operations and Comprehensive Income and produces a constant periodic rate of return on the investment in financing leases, net.

Revenue from advisory services is generated from service contracts generally based on (i) time and expense arrangements (where the Company recognizes revenues based on hours incurred and contracted rates), (ii) fixed-fee arrangements (where the Company recognizes revenues earned to date by applying the proportional performance method) or (iii) performance-based or contingent arrangements (where the Company recognizes revenues at a point in time when the client receives the benefit of the promised service). Reimbursable expenses for the advisory services, including those relating to travel, out-of-pocket expenses, outside consultants and other outside service costs, are generally included in revenues and in general and administrative expenses in the period in which the expense is incurred.

Business Combinations, Goodwill And Intangible Assets

Business Combinations, Goodwill and Intangible Assets

The Company accounts for business combinations using the acquisition method, which requires the identification of the acquirer, the determination of the acquisition date and the allocation of the purchase price paid by the acquirer to the identifiable tangible and intangible assets acquired, the liabilities assumed, including any contingent consideration and any non-controlling interest in the acquiree at their acquisition date fair values. Goodwill represents the excess of the purchase price over the fair value of net assets acquired, including the amount assigned to identifiable intangible assets. Intangible assets may include customer relationships, trademarks and acquired software. Identifiable intangible assets with finite lives are amortized over their expected useful lives. Acquisition-related costs are expensed in the periods in which the costs are incurred. The results of operations of acquired businesses are included in the Company’s Consolidated Financial Statements from the acquisition date.

The Company evaluates goodwill for impairment at least annually, or as circumstances warrant. Goodwill is evaluated at the reporting unit level by comparing the fair value of the reporting unit with its carrying amount including goodwill. An impairment of goodwill exists if the carrying amount of the reporting unit exceeds its fair value. The impairment loss is the amount by which the carrying amount exceeds the reporting unit’s fair value, limited to the total amount of goodwill allocated to that reporting unit.

Intangible assets with finite lives are amortized over their estimated useful lives and reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If an impairment indicator is present, the Company evaluates recoverability of assets to be held and used by a comparison of the carrying value of the assets with future undiscounted net cash flows expected to be generated by the assets. The Company groups assets at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows generated by other asset groups. If the total of the expected undiscounted future cash flows is less than the carrying amount of the asset group, the Company estimates the fair value of the asset group to determine whether an impairment loss should be recognized.

Fair Value of Financial Instruments

Fair Value Measurements

The following disclosure of estimated fair value was determined by management using available market information and appropriate valuation methodologies. However, considerable judgment is necessary to interpret market data and develop

estimated fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could have realized on disposition of the assets and liabilities as of September 30, 2022 and December 31, 2021. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. Cash, escrows and reserves, receivables, prepaid expenses and other assets (excluding derivatives), accounts payable and accrued expenses are carried at amounts which reasonably approximate their fair values as of September 30, 2022 and December 31, 2021 due to their short maturities.

The fair value of the Company’s borrowings under its Credit Facilities approximates carrying value because such borrowings are subject to a variable rate which reprices frequently. The fair value of the Company’s secured borrowings aggregated approximately $27.4 million and $32.1 million as compared to the principal balance of $33.1 million and $33.2 million as of September 30, 2022 and December 31, 2021, respectively. The fair value of the Company’s debt was categorized as a Level 3 basis (as provided by ASC 820, Fair Value Measurements and Disclosures). The fair value of these financial instruments was determined by using a discounted cash flow analysis based on the borrowing rates currently available to the Company for loans with similar terms and maturities. The fair value of the mortgage debt was determined by discounting the future contractual interest and principal payments by a market rate.

The Company's derivative assets and liabilities, comprised of interest rate swap derivative instruments entered into in connection with the Credit Facilities, are recorded at fair value based on a variety of observable inputs, including contractual terms, interest rate curves, yield curves, measure of volatility, and correlations of such inputs. The Company measures its derivatives at fair value on a recurring basis based on the expected size of future cash flows on a discounted basis and incorporating a measure of non-performance risk. The fair value of the Company's derivative assets and liabilities was categorized as a Level 2 basis (as provided by ASC 820, Fair Value Measurements and Disclosures). The Company considers its own credit risk, as well as the credit risk of its counterparties, when evaluating the fair value of its derivative assets and liabilities. As of September 30, 2022 and December 31, 2021, the fair value of the Company’s interest rate swap derivative assets was approximately $9.3 million and $1.0 million, respectively, included in “Prepaid expenses and other assets, net” on the Consolidated Balance Sheet.

Disclosure about fair value of assets and liabilities is based on pertinent information available to management as of September 30, 2022 and December 31, 2021. Although management is not aware of any factors that would significantly affect the fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since September 30, 2022 and current estimates of fair value may differ significantly from the amounts presented herein.

Derivative Instruments and Hedging Activities

In accordance with ASC 815, Derivatives and Hedging, the Company records all derivative instruments on the Consolidated Balance Sheets at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, 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.

The Company may enter into derivative contracts that are intended to economically hedge certain of its risks, even though hedge accounting does not apply or the Company elects not to apply hedge accounting.

Impairment

The carrying value of real estate investments and related intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment exists when the carrying amount of an asset exceeds the aggregate projected future cash flows over the anticipated holding period on an undiscounted basis. An impairment loss is measured based on the excess of the asset’s carrying amount over its estimated fair value. Impairment analyses will be based on current plans, intended holding periods and available market information at the time the analyses are prepared. If estimates of the projected future cash flows, anticipated holding periods or market conditions change, the evaluation of impairment losses may be different and such differences may be material. The evaluation of anticipated cash flows is subjective and is based, in part, on assumptions regarding future occupancy, rental rates and capital

requirements that could differ materially from actual results.

Concentration of Credit Risks

As of September 30, 2022, the Company’s properties were leased primarily to a single tenant, the USPS. For the nine months ended September 30, 2022, 15.4% of the Company’s total rental income, or $5.6 million, was concentrated in Pennsylvania. For the nine months ended September 30, 2021, 18.3% of the Company's total rental income, or $5.1 million, was concentrated in Pennsylvania. The ability of the USPS to honor the terms of its leases is dependent upon regulatory, economic, environmental or competitive conditions in Pennsylvania or other regions where the Company operates in and could have a material effect on the Company’s overall business results.

The Company has deposited cash and maintains its bank deposits with large financial institutions in amounts that, from time to time, exceed federally insured limits. The Company has not experienced any losses in such accounts.

Equity Based Compensation

The Company accounts for equity-based compensation in accordance with ASC Topic 718 Compensation – Stock Compensation, which requires the Company to recognize an expense for the grant date fair value of equity-based awards. Equity-classified stock awards granted to employees and non-employees that have a service condition and/or a market condition are measured at fair value at date of grant and remeasured at fair value only upon a modification of the award. The Company records forfeitures as they occur.

The Company recognizes compensation expense on a straight-line basis over the requisite service period of each award, with the amount of compensation expense recognized at the end of a reporting period at least equal the portion of fair value of the respective award at grant date or modification date, as applicable, that has vested through that date.

Any amount of insurance recovery in excess of the amount of the losses incurred is considered a gain contingency and is not recorded in other income until the amount is determinable and approved by the insurance company. Insurance recoveries for business interruption for lost revenue or profit are accounted for as gain contingencies in their entirety, and therefore are not recorded in income until the amount is determinable and approved by the insurance company.

Earnings per Share

The Company calculates earnings per share ("EPS") based upon the weighted average shares outstanding less issued and outstanding non-vested shares of Class A common stock. As of September 30, 2022 and 2021, the Company had unvested restricted shares of Class A common stock, long term incentive units of the Operating Partnership ("LTIP Units") and certain restricted stock units (“RSUs”), which provide for non-forfeitable rights to dividend and dividend equivalent payments. Accordingly, these unvested restricted shares of Class A common stock, LTIP Units and RSUs are considered participating securities and are included in the computation of basic and diluted EPS pursuant to the two-class method. Diluted EPS is calculated after giving effect to all potential dilutive shares outstanding during the period. See Note 10. Earnings Per Share for further details.

Recently Adopted and Future Application of Accounting Pronouncements

Future Application of Accounting Standards

In September 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and in November 2018 issued ASU No. 2018-19, Codification

Improvements to Topic 326, Financial Instruments - Credit Losses. The guidance changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The guidance replaces the current "incurred loss" model with an "expected loss" approach. The Company will also be required to disclose information about how it developed the allowances, including changes in the factors that influenced the Company’s estimate of expected credit losses and the reasons for those changes. ASU No. 2018-19 excludes operating lease receivables from the scope of this guidance. This guidance will be effective for the Company on January 1, 2023, as a result of its classification as an EGC. The Company is currently in the process of evaluating the impact the adoption of the guidance will have on its consolidated financial statements.
