Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 1. — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The consolidated financial statements include the accounts of Getty Realty Corp. and its wholly-owned subsidiaries. The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). We do not distinguish our principal business or our operations on a geographical basis for purposes of measuring performance. We manage and evaluate our operations as a single segment. All significant intercompany accounts and transactions have been eliminated. Use of Estimates, Judgments and Assumptions The consolidated financial statements have been prepared in conformity with GAAP, which requires management to make estimates, judgments 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 revenues and expenses during the period reported. Estimates, judgments and assumptions underlying the accompanying consolidated financial statements include, but are not limited to, real estate, receivables, deferred rent receivable, direct financing leases, depreciation and amortization, impairment of long-lived assets, environmental remediation costs, environmental remediation obligations, litigation, accrued liabilities, income taxes and the allocation of the purchase price of properties acquired to the assets acquired and liabilities assumed. Application of these estimates and assumptions requires exercise of judgment as to future uncertainties and, as a result, actual results could differ materially from these estimates. Reclassifications Certain prior year amounts have been reclassified to conform to current year presentation. Such reclassifications had no impact on previously reported net earnings. Real Estate Real estate assets are stated at cost less accumulated depreciation and amortization. For acquisitions of real estate we estimate the fair value of acquired tangible assets (consisting of land, buildings and improvements) “as if vacant” and identified intangible assets and liabilities (consisting of leasehold interests, above-market and below-market leases, in-place leases and tenant relationships) and assumed debt. Based on these estimates, we allocate the estimated fair value to the applicable assets and liabilities. Fair value is determined based on an exit price approach, which contemplates the price that would be received from the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assumptions used are property and geographic specific and may include, among other things, capitalization rates, market rental rates, discount rates and EBITDA to rent coverage ratios. We expense transaction costs associated with business combinations in the period incurred. Acquisitions of real estate which do not meet the definition of a business are accounted for as asset acquisitions. The accounting model for asset acquisitions is similar to the accounting model for business combinations except that the acquisition costs are capitalized and allocated to the individual assets acquired and liabilities assumed on a relative fair value basis. For additional information regarding property acquisitions, see Note 13 – Property Acquisitions. We capitalize direct costs, including costs such as construction costs and professional services, and indirect costs associated with the development and construction of real estate assets while substantive activities are ongoing to prepare the assets for their intended use. The capitalization period begins when development activities are underway and ends when it is determined that the asset is substantially complete and ready for its intended use. We evaluate the held for sale classification of our real estate as of the end of each quarter. Assets that are classified as held for sale are recorded at the lower of their carrying amount or fair value less costs to sell. When real estate assets are sold or retired, the cost and related accumulated depreciation and amortization is eliminated from the respective accounts and any gain or loss is credited or charged to income. We evaluate real estate sale transactions where we provide seller financing to determine sale and gain recognition in accordance with GAAP. Expenditures for maintenance and repairs are charged to income when incurred. Depreciation and Amortization Depreciation of real estate is computed on the straight-line method based upon the estimated useful lives of the assets, which generally range from 16 to 25 years for buildings and improvements, or the term of the lease if shorter. Asset retirement costs are depreciated over the shorter of the remaining useful lives of USTs or 10 years for asset retirement costs related to environmental remediation obligations, which costs are attributable to the group of assets identified at a property. Leasehold interests and in-place leases are amortized over the remaining term of the underlying lease. Direct Financing Leases Income under direct financing leases is included in revenues from rental properties and is recognized over the lease terms using the effective interest rate method which produces a constant periodic rate of return on the net investments in the leased properties. The investments in direct financing leases are increased for interest income earned and amortized over the life of the leases and reduced by the receipt of lease payments. We consider direct financing leases to be past-due or delinquent when a contractually required payment is not remitted in accordance with the provisions of the underlying agreement. On June 16, 2016, the Financial Accounting Standards Board (the “FASB”) issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurements of Credit Losses on Financial Instruments The accounting standard became effective for us and was adopted on January 1, 2020. Upon adoption, we had five unitary leases subject to this standard classified as a direct financing leases with a net investment balance aggregating $82,366,000 prior to the credit loss adjustment. In these direct financing leases, the payment obligations of the lessees are collateralized by real estate properties. Historically, we have had no collection issues related to these direct financing leases; therefore, we assessed the probability of default on these leases based on the lessee’s financial condition, business prospects, remaining term of the lease, expected value of the underlying collateral upon its repossession, and our historical loss experience related to other leases in which we are the lessor. Based on the aforementioned considerations, we estimated a credit loss reserve related to these direct financing leases totaling $578,000, which was recognized as a cumulative adjustment to retained earnings and as a reduction of the investment in direct financing leases balance on our consolidated balance sheets on January 1, 2020. Periods prior to the adoption date that are presented for comparative purposes were not adjusted. During the year ended December 31, 2020, we recorded an allowance for credit losses of $340,000 on our net investments in direct financing leases due to changes in expected economic conditions, which was included within other income in our consolidated statements of operations. In addition, during the year ended December 31, 2021, we reduced our allowance for credit losses by $92,000 on our net investments in direct financing leases due to changes in expected economic conditions, which was included within other income in our consolidated statements of operations. We review our direct financing leases each reporting period to determine adjust the allowance for any estimated changes in the credit loss with the resulting change recorded through our consolidated statement of operations. When we enter into a contract to sell properties that are recorded as direct financing leases, we evaluate whether we believe that it is probable that the disposition will occur. If we determine that the disposition is probable and therefore the property’s holding period is reduced, we record an allowance for credit losses to reflect the change in the estimate of the undiscounted future rents. Accordingly, the net investment balance is written down to fair value. Notes and Mortgages Receivable Notes and mortgages receivable consists of loans originated by us in conjunction with property dispositions and funding provided to tenants in conjunction with property acquisitions and capital improvements. Notes and mortgages receivable are recorded at stated principal amounts. In conjunction with our adoption of ASU 2016-13 on January 1, 2020, we which was recognized as a cumulative adjustment to retained earnings and as a reduction of the on the notes and mortgages receivable balance on our consolidated balance sheets on January 1, 2020. Periods prior to the adoption date that are presented for comparative purposes were not adjusted. During the year ended December 31, 2020, we recorded an additional allowance for credit losses of $28,000 on these notes and mortgages receivable due to changes in expected economic conditions, which was included within o ther income in our consolidated statements of operations. In addition, during the year ended December 31, 2021, we redu ced our allowance for credit losses by $ 40,000 on these notes and mortgages receivable due to changes in expected economic conditions, which was included within other income in our consolidated statements of operations From time to time, we may originate construction loans for the construction of income-producing properties. $13.5 million. During the year ended December 31, 2021, we exercised our option to purchase two properties for $10.0 million for which we had previously funded construction loans in the amount of $7.8 million, at which time the loans were repaid in full At there were $ million of outstanding balances for construction loans. Our construction loans generally provide for funding only during the construction phase, which is typically up to nine months, although our policy is to consider construction periods as long as 24 months. Funds are disbursed based on inspections in accordance with a schedule reflecting the completion of portions of the project. We also review and inspect each property before disbursement of funds during the term of the construction loan. At the end of the construction phase, the construction loan will be repaid with the proceeds from the sale of the property. We have the option to purchase the property at the end of the construction period. Cash and Cash Equivalents We consider all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. Our cash and cash equivalents are held in the custody of financial institutions, and these balances, at times, may exceed federally insurable limits. Restricted Cash Restricted cash consists of cash that is contractually restricted or held in escrow pursuant to various agreements with counterparties. At December 31, 2021 and 2020, restricted cash of $1,723,000 and $1,979,000, respectively, consisted of security deposits received from our tenants. Revenue Recognition and Deferred Rent Receivable On January 1, 2018, we adopted ASU 2014-09, Revenue from Contracts with Customers (Topic 606), (“Topic 606”) using the modified retrospective method applying it to any open contracts as of January 1, 2018. The new guidance provides a unified model to determine how revenue is recognized. To determine the proper amount of revenue to be recognized, we perform the following steps: (i) identify the contract with the customer, (ii) identify the performance obligations within the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations and (v) recognize revenue when (or as) a performance obligation is satisfied. Our primary source of revenue consists of revenue from rental properties and tenant reimbursements that is derived from leasing arrangements, which is specifically excluded from the standard, and thus had no material impact on our consolidated financial statements or notes to our consolidated financial statements as of December 31, 2021, 2020 and 2019. Lease payments from operating leases are recognized on a straight-line basis over the term of the leases. The cumulative difference between lease revenue recognized under this method and the contractual lease payment terms is recorded as deferred rent receivable on our consolidated balance sheets. We review our accounts receivable, including its deferred rent receivable, related to base rents, straight-line rents, tenant reimbursements and other revenues for collectability. Our evaluation of collectability primarily consists of reviewing past due account balances and considers such factors as the credit quality of our tenant, historical trends of the tenant, changes in tenant payment terms, current economic trends, including the novel coronavirus (“COVID-19”) pandemic, and other facts and circumstances related to the applicable tenants. In addition, with respect to tenants in bankruptcy, we estimate the probable recovery through bankruptcy claims. If a tenant’s accounts receivable balance is considered uncollectable, we will write off the related receivable balances and cease to recognize lease income, including straight-line rent unless cash is received. If the collectability assessment subsequently changes to probable, any difference between the lease income that would have been recognized if collectability had always been assessed as probable and the lease income recognized to date, is recognized as a current-period adjustment to revenues from rental properties. Our reported net earnings are directly affected by our estimate of the collectability of our accounts receivable. In April 2020, the FASB issued interpretive guidance relating to the accounting for lease concessions provided as a result of COVID-19. In this guidance, entities can elect not to apply lease modification accounting with respect to such lease concessions and instead, treat the concession as if it was a part of the existing contract. This guidance is only applicable to COVID-19 related lease concessions that do not result in a substantial increase in the rights of the lessor or the obligations of the lessee. Some concessions will provide a deferral of payments with no substantive changes to the consideration in the original contract. A deferral affects the timing of cash receipts, but the amount of the consideration is substantially the same as that required by the original contract. The FASB staff provides two ways to account for those deferrals: (1) Account for the concessions as if no changes to the lease contract were made. Under that accounting, a lessor would increase its lease receivable. In its income statement, a lessor would continue to recognize income during the deferral period. (2) Account for the deferred payments as variable lease payments. We elected to treat lease concessions with option (1) above for the year ended December 31, 2021. There were no outstanding balances for lease concessions provided as a result of COVID-19 at December 31, 2021. The present value of the difference between the fair market rent and the contractual rent for above-market and below-market leases at the time properties are acquired is amortized into revenues from rental properties over the remaining terms of the in-place leases. Lease termination fees are recognized as other income when earned upon the termination of a tenant’s lease and relinquishment of space in which we have no further obligation to the tenant. The sales of nonfinancial assets, such as real estate, are to be recognized when control of the asset transfers to the buyer, which will occur when the buyer has the ability to direct the use of or obtain substantially all of the remaining benefits from the asset. This generally occurs when the transaction closes and consideration is exchanged for control of the property. Impairment of Long-Lived Assets Assets are written down to fair value when events and circumstances indicate that the assets might be impaired and the projected undiscounted cash flows estimated to be generated by those assets are less than the carrying amount of those assets. Assets held for disposal are written down to fair value less estimated disposition costs. We recorded impairment charges aggregating $4,404,000, $4,258,000 and $4,012,000 for the years ended December 31, 2021, 2020 and 2019, respectively. Our estimated fair values, as they relate to property carrying values, were primarily based upon (i) estimated sales prices from third-party offers based on signed contracts, letters of intent or indicative bids, for which we do not have access to the unobservable inputs used to determine these estimated fair values, and/or consideration of the amount that currently would be required to replace the asset, as adjusted for obsolescence (this method was used to determine $964,000 of the $4,404,000 in impairments recognized during the year ended December 31, 2021) and (ii) discounted cash flow models (this method was used to determine $484,000 of the $4,404,000 in impairments recognized during the year ended December 31, 2021). During the year ended December 31, 2021, we recorded the remaining impairments of $2,956,000 of the $4,404,000 due to the accumulation of asset retirement costs as a result of changes in estimates associated with our estimated environmental liabilities which increased the carrying values of certain properties in excess of their fair values. For the years ended December 31, 2021, 2020 and 2019, impairment charges aggregating $919,000, $932,000 and $1,202,000, respectively, were related to properties that were previously disposed of by us. The estimated fair value of real estate is based on the price that would be received from the sale of the property in an orderly transaction between market participants at the measurement date. In general, we consider multiple internal valuation techniques when measuring the fair value of a property, all of which are based on unobservable inputs and assumptions that are classified within Level 3 of the Fair Value Hierarchy. These unobservable inputs include assumed holding periods ranging up to 15 years, assumed average rent increases of 2.0% annually, income capitalized at a rate of 8.0% and cash flows discounted at a rate of 7.0%. These assessments have a direct impact on our net income because recording an impairment loss results in an immediate negative adjustment to net income. The evaluation of anticipated cash flows is highly subjective and is based in part on assumptions regarding future rental rates and operating expenses that could differ materially from actual results in future periods. Where properties held for use have been identified as having a potential for sale, additional judgments are required related to the determination as to the appropriate period over which the projected undiscounted cash flows should include the operating cash flows and the amount included as the estimated residual value. This requires significant judgment. In some cases, the results of whether impairment is indicated are sensitive to changes in assumptions input into the estimates, including the holding period until expected sale. Fair Value of Financial Instruments All of our financial instruments are reflected in the accompanying consolidated balance sheets at amounts which, in our estimation based upon an interpretation of available market information and valuation methodologies, reasonably approximate their fair values, except those separately disclosed in the notes below. The preparation of consolidated financial statements in accordance with GAAP requires management to make estimates of fair value that affect the reported amounts of assets and liabilities and disclosure of assets and liabilities at the date of the consolidated financial statements and revenues and expenses during the period reported using a hierarchy (the “Fair Value Hierarchy”) that prioritizes the inputs to valuation techniques used to measure the fair value. The Fair Value Hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The levels of the Fair Value Hierarchy are as follows: “Level 1” – inputs that reflect unadjusted quoted prices in active markets for identical assets or liabilities that we have the ability to access at the measurement date; “Level 2” – inputs other than quoted prices that are observable for the asset or liability either directly or indirectly, including inputs in markets that are not considered to be active; and “Level 3” – inputs that are unobservable. Certain types of assets and liabilities are recorded at fair value either on a recurring or non-recurring basis. Assets required or elected to be marked-to-market and reported at fair value every reporting period are valued on a recurring basis. Other assets not required to be recorded at fair value every period may be recorded at fair value if a specific provision or other impairment is recorded within the period to mark the carrying value of the asset to market as of the reporting date. Such assets are valued on a non-recurring basis. Environmental Remediation Obligations We record the fair value of a liability for an environmental remediation obligation as an asset and liability when there is a legal obligation associated with the retirement of a tangible long-lived asset and the liability can be reasonably estimated. Environmental remediation obligations are estimated based on the level and impact of contamination at each property. The accrued liability is the aggregate of our estimate of the fair value of cost for each component of the liability. The accrued liability is net of estimated recoveries from state UST remediation funds considering estimated recovery rates developed from prior experience with the funds. Net environmental liabilities are currently measured based on their expected future cash flows which have been adjusted for inflation and discounted to present value. We accrue for environmental liabilities that we believe are allocable to other potentially responsible parties if it becomes probable that the other parties will not pay their environmental remediation obligations. Litigation Legal fees related to litigation are expensed as legal services are performed. We provide for litigation accruals, including certain litigation related to environmental matters, when it is probable that a liability has been incurred and a reasonable estimate of the liability can be made. If the estimate of the liability can only be identified as a range, and no amount within the range is a better estimate than any other amount, the minimum of the range is accrued for the liability. We accrue our share of environmental litigation liabilities based on our assumptions of the ultimate allocation method and share that will be used when determining our share of responsibility. Income Taxes We file a federal income tax return on which are consolidated our tax items and the tax items of our subsidiaries that are pass-through entities. Effective January 1, 2001, we elected to qualify, and believe that we are operating so as to qualify, as a REIT for federal income tax purposes. Accordingly, we generally will not be subject to federal income tax on qualifying REIT income, provided that distributions to our stockholders equal at least the amount of our taxable income as defined under the Internal Revenue Code. We accrue for uncertain tax matters when appropriate. The accrual for uncertain tax positions is adjusted as circumstances change and as the uncertainties become more clearly defined, such as when audits are settled or exposures expire. Tax returns for the years 2018, 2019 and 2020, and tax returns which will be filed for the year ended 2021, remain open to examination by federal and state tax jurisdictions under the respective statutes of limitations. New Accounting Pronouncements On March 12, 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) (“ASU 2020-04”). ASU 2020-04 contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. The guidance in ASU 2020-04 provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. We are currently evaluating the impact the adoption of ASU 2020-04 will have on our consolidated financial statements .

Leases [Abstract]
Leases	NOTE 2. — LEASES As of December 31, 2021, we owned 981 properties and leased 47 properties from third-party landlords. These 1,028 properties are located in 38 states across the United States and Washington, D.C. Substantially all of our properties are leased on a triple-net basis to convenience store operators, petroleum distributors, car wash operators and other automotive-related and retail tenants. Our tenants either operate their business at our properties directly or, in the case of certain convenience stores and gasoline and repair stations, sublet our properties and supply fuel to third parties that operate the businesses. Our triple-net lease tenants are responsible for the payment of all taxes, maintenance, repairs, insurance and other operating expenses relating to our properties, and are also responsible for environmental contamination occurring during the terms of their leases and in certain cases also for environmental contamination that existed before their leases commenced. For additional information regarding our environmental obligations , see Note 5 – Environmental Obligations . Significant portion of our tenants’ financial results depend on convenience store sales, the sale of refined petroleum products and/or the sale of automotive services and parts. As a result, our tenants’ financial results can be dependent on the performance of the automobile manufacturing, petroleum marketing and automobile aftermarket industries, each of which are highly competitive and can be subject to variability. During the terms of our leases, we monitor the credit quality of our triple-net lease tenants by reviewing their published credit rating, if available, reviewing publicly available financial statements, or reviewing financial or other operating statements which are delivered to us pursuant to applicable lease agreements, monitoring news reports regarding our tenants and their respective businesses, and monitoring the timeliness of lease payments and the performance of other financial covenants under their leases. We adopted ASU 2016-02 as of January 1, 2019. ASU 2016-02 amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets. Under ASU 2016-02, lessor accounting will remain similar to lessor accounting under previous GAAP, while aligning with the FASB’s new revenue recognition guidance. For leases in which we are the lessor, we are (i) retaining classification of our historical leases as we are not required to reassess classification upon adoption of the new standard, (ii) expensing indirect leasing costs in connection with new or extended tenant leases, the recognition of which would have been deferred under prior accounting guidance and (iii) aggregating revenue from our lease components and non-lease components (comprised of tenant reimbursements) into revenue from rental properties. Revenues from rental properties for the years ended December 31, 2021, 2020 and 2019, were $153,886,000, $144,601,000 and $137,736,000, respectively. Rental income contractually due from our tenants included in revenues from rental properties was $138,691,000, $128,246,000 and $119,293,000 for the years ended December 31, 2021, 2020 and 2019, respectively. In accordance with GAAP, we recognize rental revenue in amounts which vary from the amount of rent contractually due during the periods presented. As a result, revenues from rental properties include non-cash adjustments recorded for deferred rental revenue due to the recognition of rental income on a straight-line basis over the current lease term, the net amortization of above-market and below-market leases, rental income recorded under direct financing leases using the effective interest method which produces a constant periodic rate of return on the net investments in the leased properties and the amortization of deferred lease incentives (collectively, “Revenue Recognition Adjustments”). Revenue Recognition Adjustments included in revenues from rental properties resulted in a reduction in revenue of $1,964,000 and $895,000, for the year ended December 31, 2021 and 2020, respectively, and increases in revenue of $960,000 for the year ended December 31, Tenant reimbursements, which are included in revenues from rental properties and which consist of real estate taxes and other municipal charges paid by us which were reimbursed by our tenants pursuant to the terms of triple-net lease agreements, were $17,159,000, $17,250,000 and $17,483,000 for the years ended December 31, 2021, 2020 and 2019, respectively. We incurred $298,000, $351,000 and $373,000 of lease origination costs for the years ended December 31, 2021, 2020 and 2019, respectively. This deferred expense is recognized on a straight-line basis as amortization expense in our consolidated statements of operations over the terms of the various leases. The components of the $71,647,000 investment in direct financing leases as of December 31, 2021 are lease payments receivable of $98,539,000 plus unguaranteed estimated residual value of $13,928,000 less unearned income of $39,994,000 and $826,000 allowance for credit losses. The components of the $77,238,000 investment in direct financing leases as of December 31, 2020 are lease payments receivable of $113,256,000 plus unguaranteed estimated residual value of $13,928,000 less unearned income of $49,028,000 and $918,000 allowance for credit losses. In accordance with ASU 2016-13, we applied changes in loss reserves related to these direct financing leases totaling $578,000, as a cumulative adjustment to retained earnings and as a reduction of the investment in direct financing leases balance on our consolidated balance sheets on January 1, 2020. Future contractual annual rentals receivable from our tenants, which have terms in excess of one year as of December 31, 2021, are as follows (in thousands): Operating Leases Direct Financing Leases 2022 $ 131,868 $ 13,203 2023 131,442 13,237 2024 129,834 13,380 2025 129,466 13,412 2026 116,994 10,386 Thereafter 651,396 34,921 Total $ 1,291,000 $ 98,539 For leases in which we are the lessee, ASU 2016-02 requires leases with durations greater than twelve months to be recognized on our consolidated balance sheets. We elected the package of transition provisions available for expired or existing contracts, which allowed us to carryforward our historical assessments of (i) whether contracts are or contain leases, (ii) lease classification and (iii) initial direct costs. As of January 1, 2019, we recognized operating lease right-of-use assets of $25,561,000 (net of deferred rent expense) and operating lease liabilities of $26,087,000, which were presented on our consolidated financial statements. The right-of-use assets and lease liabilities are carried at the present value of the remaining expected future lease payments. When available, we use the rate implicit in the lease to discount lease payments to present value; however, our current leases did not provide a readily determinable implicit rate. Therefore, we estimated our incremental borrowing rate to discount the lease payments based on information available and considered factors such as interest rates available to us on a fully collateralized basis and terms of the leases. ASU 2016-02 did not have a material impact on our consolidated balance sheets or on our consolidated statements of operations. The most significant impact was the recognition of right-of-use assets and lease liabilities for operating leases, while our accounting for finance leases remained substantially unchanged. The following presents the lease-related assets and liabilities (in thousands): December 31, 2021 Assets Right-of-use assets – operating $ 21,092 Right-of-use assets – finance 379 Total lease assets $ 21,471 Liabilities Lease liability – operating $ 22,980 Lease liability – finance 2,005 Total lease liabilities $ 24,985 The following presents the weighted average lease terms and discount rates of our leases: Weighted-average remaining lease term (years) Operating leases 8.8 Finance leases 6.8 Weighted-average discount rate Operating leases (a) 4.80 % Finance leases 16.90 % (a) Upon adoption of the new lease standard, discount rates used for existing leases were established at January 1, 2019. The following presents our total lease costs (in thousands): December 31, 2021 Operating lease cost $ 4,240 Finance lease cost Amortization of leased assets 645 Interest on lease liabilities 615 Short-term lease cost - Total lease cost $ 5,500 The following presents supplemental cash flow information related to our leases (in thousands): December 31, 2021 Cash paid for amounts included in the measurement of lease liabilities Operating cash flows for operating leases $ 3,255 Operating cash flows for finance leases 615 Financing cash flows for finance leases $ 645 As of December 31, 2021, scheduled lease liabilities mature as follows (in thousands): Operating Leases Direct Financing Leases 2022 $ 3,795 $ 838 2023 3,695 586 2024 3,549 515 2025 3,173 362 2026 2,963 265 Thereafter 11,213 523 Total lease payments 28,388 3,089 Less: amount representing interest (5,408 ) (1,084 ) Present value of lease payments $ 22,980 $ 2,005 We have obligations to lessors under non-cancelable operating leases which have terms in excess of one year, principally for convenience store and gasoline station properties. The leased properties have a remaining lease term averaging approximately eight years, including renewal options. Future minimum annual rentals payable under such leases, excluding renewal options, are as follows: 2022 – $3,821,000, 2023 – $3,267,000, 2024 – $2,614,000, 2025 – $1,825,000, 2026 – $1,471,000 and $2,738,000 thereafter. Rent expense, substantially all of which consists of minimum rentals on non-cancelable operating leases, amounted to $3,393,000, $3,769,000 and $4,664,000 for the years ended December 31, 2021, 2020 and 2019, respectively, and is included in property costs. Rent received under subleases for the years ended December 31, 2021, 2020 and 2019, was $7,333,000, $7,892,000 and $8,699,000, respectively, and is included in rental revenue discussed above. Major Tenants As of December 31, 2021, we had four significant tenants by revenue: • We leased 150 properties in three separate unitary leases and two stand-alone leases to subsidiaries of Global Partners LP (NYSE: GLP) (“Global”). In the aggregate, our leases with subsidiaries of Global represented 16% of our total revenues for the years ended December 31, 2021 and 2020. All of our unitary leases with subsidiaries of Global are guaranteed by the parent company. • We leased 128 properties in four separate unitary leases to subsidiaries of ARKO Corp . (NASDAQ: ARKO) (“Arko”). In the aggregate, our leases with subsidiaries of Arko represented 14% and 15% of our total revenues for the years ended December 31, 2021 and 2020, respectively. All of our unitary leases with subsidiaries of Arko are guaranteed by the parent company. • We leased 78 properties pursuant to three separate unitary leases and one stand-alone lease to Apro, LLC (d/b/a “United Oil”). In the aggregate, our leases with United Oil represented 11% and 12% of our total revenues for the years ended December 31, 2021 and 2020, respectively. • We leased 69 properties pursuant to two separate unitary leases to subsidiaries of Chestnut Petroleum Dist., Inc. (“Chestnut”). In the aggregate, our leases with subsidiaries of Chestnut represented 9% and 10% of our total revenues for the years ended December 31, 2021 and 2020, respectively. The largest of these unitary leases, covering 52 of our properties, is guaranteed by the parent company, its principals and numerous Chestnut affiliates. Getty Petroleum Marketing Inc. Getty Petroleum Marketing Inc. (“Marketing”) was our largest tenant from 1997 until 2012 under a unitary triple-net master lease that was terminated in April 2012 as a consequence of Marketing’s bankruptcy, at which time we either sold or released these properties. As of December 31, 2021, 342 of the properties we own or lease were previously leased to Marketing, of which 310 properties are subject to long-term triple-net leases with petroleum distributors in 14 separate property portfolios and 24 properties are leased as single unit triple-net leases. The leases covering properties previously leased to Marketing are unitary triple-net lease agreements generally with an initial term of 15 years and options for successive renewal terms of up to 20 years. Rent is scheduled to increase at varying intervals during both the initial and renewal terms of the leases. Several of the leases provide for additional rent based on the aggregate volume of fuel sold. In addition, the majority of the leases require the tenants to invest capital in our properties, substantially all of which are related to the replacement of USTs that are owned by our tenants. As of December 31, 2021, we have a remaining commitment to fund up to $6,616,000 in the aggregate with our tenants for our portion of such capital improvements. Our commitment provides us with the option to either reimburse our tenants or to offset rent when these capital expenditures are made. This deferred expense is recognized on a straight-line basis as a reduction of rental revenue in our consolidated statements of operations over the life of the various leases. As part of the triple-net leases for properties previously leased to Marketing, we transferred title of the USTs to our tenants, and the obligation to pay for the retirement and decommissioning or removal of USTs at the end of their useful lives, or earlier if circumstances warranted, was fully or partially transferred to our new tenants. We remain contingently liable for this obligation in the event that our tenants do not satisfy their responsibilities. Accordingly, through December 31, 2021, we removed $13,813,000 of asset retirement obligations and $10,808,000 of net asset retirement costs related to USTs from our balance sheet. The cumulative change of $1,104,000 (net of accumulated amortization of $1,901,000) is recorded as deferred rental revenue and will be recognized on a straight-line basis as additional revenues from rental properties over the terms of the various leases.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE 3. — COMMITMENTS AND CONTINGENCIES Credit Risk In order to minimize our exposure to credit risk associated with financial instruments, we place our temporary cash investments, if any, with high credit quality institutions. Temporary cash investments, if any, are currently held in an overnight bank time deposit with JPMorgan Chase Bank, N.A. and these balances, at times, may exceed federally insurable limits. Legal Proceedings We are involved in various legal proceedings and claims which arise in the ordinary course of our business. As of December 31, 2021 and 2020, we had accrued $1,925,000 and $4,275,000, respectively, for certain of these matters which we believe were appropriate based on information then currently available. Matters related to our former Newark, New Jersey Terminal and the Lower Passaic River. In 2004, the United States Environmental Protection Agency (“EPA”) issued General Notice Letters (“GNL”) to over 100 entities, including us, alleging that they are PRPs at the Diamond Alkali Superfund Site (“Superfund Site”), which includes the former Diamond Shamrock Corporation manufacturing facility located at 80-120 Lister Ave. in Newark, New Jersey and a 17-mile stretch of the Passaic River from Dundee Dam to the Newark Bay and its tributaries (the Lower Passaic River Study Area or “LPRSA”). In May 2007, over 70 GNL recipients, including us, entered into an Administrative Settlement Agreement and Order on Consent (“AOC”) with the EPA to perform a Remedial Investigation and Feasibility Study (“RI/FS”) for the LPRSA, which is intended to address the investigation and evaluation of alternative remedial actions with respect to alleged damages to the LPRSA. Many of the parties to the AOC, including us, are also members of a Cooperating Parties Group (“CPG”). The CPG agreed to an interim allocation formula for purposes of allocating the costs to complete the RI/FS among its members, with the understanding that this interim allocation formula is not binding on the parties in terms of any potential liability for the costs to remediate the LPRSA. The CPG submitted to the EPA its draft RI/FS in 2015, which sets forth various alternatives for remediating the entire 17 miles of the LPRSA. In October 2018, the EPA issued a letter directing the CPG to prepare a streamlined feasibility study for just the upper 9-miles of the LPRSA based on an iterative approach using adaptive management strategies. On December 4, 2020, The CPG submitted a Final Draft Interim Remedy Feasibility Study (“IR/FS”) to the EPA which identifies various targeted dredge and cap alternatives for the upper 9-miles of the LPRSA. On December 11, 2020, the EPA conditionally approved the CPG’s IR/FS for the upper 9-miles of the LPRSA, which recognizes that interim actions and adaptive management may be appropriate before deciding a final remedy. The EPA published the Proposed Plan for the upper 9-mile IR/FS for public comment and subsequently issued a Record of Decision (“ROD”) for the upper 9-mile IR/FS (“Upper 9-mile IR ROD”). There is currently no mechanism in place requiring any parties to implement the U pper 9-mile IR ROD . In addition to the RI/FS activities, other actions relating to the investigation and/or remediation of the LPRSA have proceeded as follows. First, in June 2012, certain members of the CPG entered into an Administrative Settlement Agreement and Order on Consent (“10.9 AOC”) with the EPA to perform certain remediation activities, including removal and capping of sediments at the river mile 10.9 area and certain testing. The EPA also issued a Unilateral Order to Occidental Chemical Corporation (“Occidental”), the former owner/operator of the Diamond Shamrock Corporation facility responsible for the discharge of 2,3,8,8-TCDD (“dioxin”) and other hazardous substances from the Lister facility. The Order directed Occidental to participate and contribute to the cost of the river mile 10.9 work. Concurrent with the CPG’s work on the RI/FS, on April 11, 2014, the EPA issued a draft Focused Feasibility Study (“FFS”) with proposed remedial alternatives to remediate the lower 8-miles of the LPRSA. The FFS was subject to public comments and objections and, on March 4, 2016, the EPA issued a ROD for the lower 8-miles (“Lower 8-mile ROD”) selecting a remedy that involves bank-to-bank dredging and installing an engineered cap with an estimated cost of $1,380,000,000. On March 31, 2016, we and more than 100 other PRPs received from the EPA a “Notice of Potential Liability and Commencement of Negotiations for Remedial Design” (“Notice”), which informed the recipients that the EPA intends to seek an Administrative Order on Consent and Settlement Agreement with Occidental (who the EPA considers the primary contributor of dioxin and other pesticides generated from the production of Agent Orange at its Diamond Shamrock Corporation facility and a discharger of other contaminants of concern (“COCs”) to the Superfund Site for remedial design of the remedy selected in the Lower 8-mile ROD, after which the EPA plans to begin negotiations with “major” PRPs for implementation and/or payment of the selected remedy. The Notice also stated that the EPA believes that some of the PRPs and other parties not yet identified will be eligible for a cash out settlement with the EPA. On September 30, 2016, Occidental entered into an agreement with the EPA to perform the remedial design for the Lower 8-mile ROD. In December 2019, Occidental submitted a report to the EPA on the progress of the remedial design work, which is still ongoing. Occidental has asserted that it is entitled to indemnification by Maxus Energy Corporation (“Maxus”) and Tierra Solutions, Inc. (“Tierra”) for its liability in connection with the Site. Occidental has also asserted that Maxus and Tierra’s parent company, YPF, S.A. (“YPF”) and certain of its affiliates must indemnify Occidental. On June 16, 2016, Maxus and Tierra filed for reorganization under Chapter 11 of the U.S. Bankruptcy Code. In July 2017, an amended Chapter 11 plan of liquidation became effective and, in connection therewith, Maxus and Tierra entered into a mutual contribution release agreement with certain parties, including us, pertaining to certain past costs, but not future remedy costs. By letter dated March 30, 2017, the EPA advised the recipients of the Notice that it would be entering into cash out settlements with 20 PRPs to resolve their alleged liability for the remedial actions addressed in the Lower 8-mile ROD, who the EPA stated did not discharge any of the eight hazardous substances identified as a COC in the ROD. The letter also stated that other parties who did not discharge dioxins, furans or polychlorinated biphenyls (which are considered the COCs posing the greatest risk to the river) may also be eligible for cash out settlements, and that the EPA would begin a process for identifying other PRPs for negotiation of future cash out settlements. We were not included in the initial group of 20 parties identified by the EPA for cash out settlements, but we believe we meet the EPA’s criteria for a cash out settlement and should be considered for same in any future discussions. In January 2018, the EPA published a notice of its intent to enter into a final settlement agreement with 15 of the initial group of parties to resolve their respective alleged liability for the Lower 8-mile ROD work, each for a payment to the EPA in the amount of $280,600. In August 2017, the EPA appointed an independent third-party allocation expert to conduct allocation proceedings with most of the remaining recipients of the Notice, which process has concluded leading to an agreement in principle between the EPA and certain of the allocation proceeding participants, including us, concerning a cash-out settlement for the entire 17-mile stretch of the Lower Passaic River and its tributaries, which is subject to negotiation and court approval and entry of a consent decree. On June 30, 2018, Occidental filed a complaint in the United States District Court for the District of New Jersey seeking cost recovery and contribution under the Comprehensive Environmental Response, Compensation, and Liability Act for its alleged expenses with respect to the investigation, design, and anticipated implementation of the remedy for the Lower 8-mile ROD work the (“Occidental lawsuit”). The complaint lists over 120 defendants, including us, many of whom were also named in the EPA’s 2016 Notice. Factual discovery is ongoing, and we are defending the claims consistent with our defenses in the related proceedings. In January 2022, the defendants in the Occidental lawsuit , including us, collectively filed a motion seeking the Court’s permission to file a motion to stay the litigation to allow the related allocation proceedings and resulting settlement discussions with the EPA to continue unencumbered by the time and costs of litigation and discovery that could later be obviated by a settlement. The Court is currently considering whether to rule on this motion for a stay of the proceedings . Based on currently known facts and circumstances, including, among other factors, the agreement in principle with the EPA noted above, anticipated allocations, our belief that there was not any use or discharge of dioxins, furans or polychlorinated biphenyls in connection with our former petroleum storage operations at our former Newark, New Jersey Terminal, and because there are numerous other parties who will likely bear the costs of remediation and/or damages, the Company does not believe that resolution of this matter as relates to the Company is reasonably likely to have a material impact on our results of operations. Nevertheless, in the event the agreement in principle is not approved by the Court, and/or there are one or more adverse determinations related to this matter, performance of the EPA’s selected remedies for the LPRSA may be subject to future negotiation, potential enforcement proceedings and/or possible litigation; hence our ultimate liability in the pending and possible future proceedings pertaining to the LPRSA remains uncertain and subject to numerous contingencies which cannot be predicted and the outcome of which are not yet known. For these reasons, we are unable to estimate a possible loss or range of loss in excess of the amount we have accrued for the Lower Passaic River proceedings as of the date of this Annual Report on Form 10-K, and it is therefore possible that losses related to the Lower Passaic River proceedings could exceed the amounts accrued as of the date hereof, which could cause a material adverse effect on our results of operations. MTBE Litigation – State of Pennsylvania On July 7, 2014, our subsidiary, Getty Properties Corp., was served with a complaint filed by the Commonwealth of Pennsylvania (the “State”) in the Court of Common Pleas, Philadelphia County relating to alleged statewide MTBE contamination in Pennsylvania. The named plaintiff is the State, by and through (then) Pennsylvania Attorney General Kathleen G. Kane (as Trustee of the waters of the State), the Pennsylvania Insurance Department (which governs and administers the Underground Storage Tank Indemnification Fund), the Pennsylvania Department of Environmental Protection (vested with the authority to protect the environment) and the Pennsylvania Underground Storage Tank Indemnification Fund. The complaint names us and more than 50 other petroleum refiners, manufacturers, distributors and retailers of MTBE or gasoline containing MTBE who are alleged to have distributed, stored and sold MTBE gasoline in Pennsylvania. The complaint seeks compensation for natural resource damages and for injuries sustained as a result of “defendants’ unfair and deceptive trade practices and act in the marketing of MTBE and gasoline containing MTBE.” The plaintiffs also seek to recover costs paid or incurred by the State to detect, treat and remediate MTBE from public and private water wells and groundwater. The plaintiffs assert causes of action against all defendants based on multiple theories, including strict liability – defective design; strict liability – failure to warn; public nuisance; negligence; trespass; and violation of consumer protection law. The case was filed in the Court of Common Pleas, Philadelphia County, but was removed by defendants to the United States District Court for the Eastern District of Pennsylvania and then transferred to the United States District Court for the Southern District of New York so that it may be managed as part of the ongoing MTBE MDL proceedings. In November 2015, plaintiffs filed a Second Amended Complaint naming additional defendants and adding factual allegations against the defendants. We joined with other defendants in the filing of a motion to dismiss the claims against us, which was granted in part and denied in part. We are vigorously defending the claims made against us. Our ultimate liability in this proceeding is uncertain and subject to numerous contingencies which cannot be predicted and the outcome of which are not yet known. MTBE Litigation – State of Maryland On December 17, 2017, the State of Maryland, by and through the Attorney General on behalf of the Maryland Department of Environment and the Maryland Department of Health (the “State of Maryland”), filed a complaint in the Circuit Court for Baltimore City related to alleged statewide MTBE contamination in Maryland. The complaint was served upon us on January 19, 2018. The complaint names us and more than 60 other defendants. The complaint seeks compensation for natural resource damages and for injuries sustained as a result of the defendants’ unfair and deceptive trade practices in the marketing of MTBE and gasoline containing MTBE. The plaintiffs also seek to recover costs paid or incurred by the State of Maryland to detect, investigate, treat and remediate MTBE from public and private water wells and groundwater, punitive damages and the award of attorneys’ fees and litigation costs. The plaintiffs assert causes of action against all defendants based on multiple theories, including strict liability – defective design; strict liability – failure to warn; strict liability for abnormally dangerous activity; public nuisance; negligence; trespass; and violations of Titles 4, 7 and 9 of the Maryland Environmental Code. On February 14, 2018, defendants removed the case to the United States District Court for the District of Maryland. We are vigorously defending the claims made against us. Our ultimate liability, if any, in this proceeding is uncertain and subject to numerous contingencies which cannot be predicted and the outcome of which are not yet known .

Credit Agreement On June 2, 2015, we entered into a $225,000,000 senior unsecured credit agreement (the “Credit Agreement”) with a group of banks led by Bank of America, N.A. The Credit Agreement consisted of a $175,000,000 unsecured revolving credit facility (the “Revolving Facility”) and a $50,000,000 unsecured term loan (the “Term Loan”). On March 23, 2018, we entered into an amended and restated credit agreement (as amended, the “Restated Credit Agreement”) amending and restating our Credit Agreement. Pursuant to the Restated Credit Agreement, we (a) increased the borrowing capacity under the Revolving Facility from $175,000,000 to $250,000,000, (b) extended the maturity date of the Revolving Facility from June 2018 June 2020 On September 19, 2018, we entered into an amendment (the “First Amendment”) of our Restated Credit Agreement. The First Amendment modifies the Restated Credit Agreement to, among other things: (i) reflect that we had previously entered into (a) an amended and restated note purchase and guarantee agreement with The Prudential Insurance Company of America (“Prudential”) and certain of its affiliates and (b) a note purchase and guarantee agreement with the Metropolitan Life Insurance Company (“MetLife”) and certain of its affiliates; and (ii) permit borrowings under each of the Revolving Facility and the Term Loan at three different interest rates, including a rate based on the LIBOR Daily Floating Rate (as defined in the First Amendment) plus the Applicable Rate (as defined in the First Amendment) for such facility. On September 12, 2019, in connection with prepayment of the Term Loan, we entered into a consent and amendment (the “Second Amendment”) of our Restated Credit Agreement. The Second Amendment modifies the Restated Credit Agreement to, among other things, (a) increase our borrowing capacity under the Revolving Facility from $250,000,000 to $300,000,000 and (b) decrease lender commitments under the Term Loan to $0. On October 27, 2021, we entered into second amended and restated credit agreement (as amended, the “Second Restated Credit Agreement”) amending and restating our Restated Credit Agreement. Pursuant to the Second Restated Credit Agreement, we (i) extended the maturity date of the Revolving Facility from March 2022 October 2025 The Second Restated Credit Agreement provides for the Revolving Facility in an aggregate principal amount of $300,000,000 and includes an accordion feature to increase the revolving commitments or add one or more tranches of term loans up to an additional aggregate amount not to exceed $300,000,000, subject to certain conditions, including one or more new or existing lenders agreeing to provide commitments for such increased amount and that no default or event of default shall have occurred and be continuing under the terms of the Revolving Facility. The Revolving Facility matures October 27, 2025, subject to two six-month extensions (for a total of 12 months) exercisable at the Company's option. The Company's exercise of an extension option is subject to the absence of any default under the Second Restated Credit Agreement and the Company's compliance with certain conditions, including the payment of extension fees to the Lenders under the Revolving Facility and that no default or event of default shall have occurred and be continuing under the terms of the Revolving Facility. The Second Restated Credit Agreement reflects reductions in the interest rates for borrowings under the Revolving Facility and permits borrowings at an interest rate equal to the sum of a base rate plus a margin of 0.30% to 0.90% or a LIBOR rate plus a margin of 1.30% to 1.90% based on the Company’s consolidated total indebtedness to total asset value ratio at the end of each quarterly reporting period. The Revolving Facility includes customary LIBOR transition language that addresses the succession of LIBOR at a future date. The per annum rate of the unused line fee on the undrawn funds under the Revolving Facility is 0.15% to 0.25% based on the Company’s daily unused portion of the available Revolving Facility. The Second Restated Credit Agreement contains customary financial covenants, including covenants with respect to total leverage, secured leverage and unsecured leverage ratios, fixed charge and interest coverage ratios, and minimum tangible net worth, as well as limitations on restricted payments, which may limit the Company’s ability to incur additional debt or pay dividends. The Second Restated Credit Agreement contains customary events of default, including cross default provisions with respect to the Company’s existing senior unsecured notes. Any event of default, if not cured or waived in a timely manner, could result in the acceleration of the Company’s indebtedness under the Second Restated Credit Agreement and could also give rise to an event of default and the acceleration of the Company’s existing senior unsecured notes. Senior Unsecured Notes On December 4, 2020, we entered into a fifth amended and restated note purchase and guarantee agreement (the “Fifth Amended and Restated Prudential Agreement”) with Prudential and certain of its affiliates amending and restating our existing fourth amended and restated note purchase and guarantee agreement. Pursuant to the Fifth Amended and Restated Prudential Agreement, we issued $100.0 million of 3.43% Series I Guaranteed Senior Notes due November 25, 2030 (the “Series I Notes”) to Prudential, and completed the early redemption of . The other senior unsecured notes outstanding under the fourth On December 4, 2020, we entered into a first amended and restated note purchase and guarantee agreement (the “First Amended and Restated AIG Agreement”) with American General Life Insurance Company amending and restating our existing note purchase and guarantee agreement. Pursuant to the First Amended and Restated AIG Agreement, we issued $50.0 million of 3.43% Series J Guaranteed Senior Notes due November 25, 2030 (the “Series J Notes”) to AIG. The $50.0 million of 3.52% Series G Guaranteed Senior Notes due September 12, 2029 (the “Series G Notes”) that were outstanding under the existing note purchase and guarantee agreement remain outstanding under the First Amended and Restated AIG Agreement. On December 4, 2020, we entered into a first amended and restated note purchase and guarantee agreement (the “First Amended and Restated MassMutual Agreement”) with Massachusetts Mutual Life Insurance Company and certain of its affiliates On June 21, 2018, we entered into a note purchase and guarantee agreement (the “MetLife Note Agreement”) with MetLife and certain of its affiliates. Pursuant to the MetLife Note Agreement, we issued $50,000,000 of 5.47% Series E Guaranteed Senior Notes due June 21, 2028 (the “Series E Notes). On October 27, 2021, we entered into amendments to each of the note purchase and guarantee agreements governing the senior unsecured notes in order to conform the financial covenants therein to the corresponding provisions in the Second Restated Credit Agreement. Covenants The Second Restated Credit Agreement and our senior unsecured notes contain customary financial covenants such as leverage, coverage ratios and minimum tangible net worth, as well as limitations on restricted payments, which may limit our ability to incur additional debt or pay dividends. The Second Restated Credit Agreement and our senior unsecured notes also contain customary events of default, including cross defaults to each other, change of control and failure to maintain REIT status (provided that the senior unsecured notes require a mandatory offer to prepay the notes upon a change in control in lieu of a change of control event of default). Any event of default, if not cured or waived in a timely manner, would increase by 200 basis points ( 2.00 %) the interest rate we pay under the Second Restated Credit Agreement and our senior unsecured notes , and could result in the acceleration of our indebtedness under the Second Restated Credit Agreement and our senior unsecured notes . We may be prohibited from drawing funds under the Revolving Facility if there is any event or condition that constitutes an event of default under the Second Restated Credit Agreement or that, with the giving of any notice, the passage of time, or both, would be an event of default under the Second Restated Credit Agreement. As of December 31, 2021, we are in compliance with all of the material terms of the Second Restated Credit Agreement and our senior unsecured notes, including the various financial covenants described herein. Debt Maturities As of December 31, 2021, scheduled debt maturities, including balloon payments, are as follows (in thousands): Revolving Facility Senior Unsecured Notes Total 2022 $ — $ — $ — 2023 — 75,000 75,000 2024 — — — 2025 60,000 50,000 110,000 2026 — — — Thereafter — 400,000 400,000 Total $ 60,000 $ 525,000 $ 585,000 (a) The Revolving Facility matures in October 2025.

Environmental Obligations

Environmental Remediation Obligations [Abstract]
Environmental Obligations	NOTE 5. — ENVIRONMENTAL OBLIGATIONS We are subject to numerous federal, state and local laws and regulations, including matters relating to the protection of the environment such as the remediation of known contamination and the retirement and decommissioning or removal of long-lived assets including buildings containing hazardous materials, USTs and other equipment. Environmental costs are principally attributable to remediation costs which are incurred for, among other things, removing USTs, excavation of contaminated soil and water, installing, operating, maintaining and decommissioning remediation systems, monitoring contamination and governmental agency compliance reporting required in connection with contaminated properties. We enter into leases and various other agreements which contractually allocate responsibility between the parties for known and unknown environmental liabilities at or relating to the subject properties. We are contingently liable for these environmental obligations in the event that our tenant does not satisfy them, and we are required to accrue for environmental liabilities that we believe are allocable to others under our leases if we determine that it is probable that our tenant will not meet its environmental obligations. It is possible that our assumptions regarding the ultimate allocation method and share of responsibility that we used to allocate environmental liabilities may change, which may result in material adjustments to the amounts recorded for environmental litigation accruals and environmental remediation liabilities. We assess whether to accrue for environmental liabilities based upon relevant factors including our tenants’ histories of paying for such obligations, our assessment of their financial capability, and their intent to pay for such obligations. However, there can be no assurance that our assessments are correct or that our tenants who have paid their obligations in the past will continue to do so. We may ultimately be responsible to pay for environmental liabilities as the property owner if our tenant fails to pay them. The estimated future costs for known environmental remediation requirements are accrued when it is probable that a liability has been incurred and a reasonable estimate of fair value can be made. The accrued liability is the aggregate of our estimate of the fair value of cost for each component of the liability, net of estimated recoveries from state UST remediation funds considering estimated recovery rates developed from prior experience with the funds. first 10 years of the lease term (or a shorter period for a minority of such leases). After expiration of such 10-year (or, in certain cases, shorter) period, responsibility for all newly discovered contamination, even if it relates to periods prior to commencement of the lease, is contractually allocated to our tenant. Our tenants at properties previously leased to Marketing are in all cases responsible for the cost of any remediation of contamination that results from their use and occupancy of our properties. Under substantially all of our other triple-net leases, responsibility for remediation of all environmental contamination discovered during the term of the lease (including known and unknown contamination that existed prior to commencement of the lease) is the responsibility of our tenant. We anticipate that USTs at a number of properties we currently own and which were previously leased to Marketing will be replaced in the years ahead as these USTs near the end of their useful lives. In the course of certain UST removals and replacements at properties previously leased to Marketing where we retained continuing responsibility for preexisting environmental obligations, previously unknown environmental contamination was and continues to be discovered. As a result, we have developed an estimate of fair value for the prospective future environmental liability resulting from preexisting unknown environmental contamination and have accrued for these estimated costs. These estimates are based primarily upon quantifiable trends which we believe allow us to make reasonable estimates of fair value for the future costs of environmental remediation resulting from the removal and replacement of USTs. Our accrual of the additional liability represents our estimate of the fair value of cost for each component of the liability, net of estimated recoveries from state UST remediation funds considering estimated recovery rates developed from prior experience with the funds. In arriving at our accrual, we analyzed the ages of USTs at properties where we would be responsible for preexisting contamination found within 10 years after commencement of a lease (for properties subject to long-term triple-net leases) or five years from a sale (for divested properties), and projected a cost to closure for preexisting unknown environmental contamination. We measure our environmental remediation liabilities at fair value based on expected future net cash flows, adjusted for inflation (using a range of 2.0% to 2.75%), and then discount them to present value (using a range of 4.0% to 7.0%). We adjust our environmental remediation liabilities quarterly to reflect changes in projected expenditures, changes in present value due to the passage of time and reductions in estimated liabilities as a result of actual expenditures incurred during each quarter. As of December 31, 2021, we had accrued a total of $47,597,000 for our prospective environmental remediation obligations. This accrual consisted of (a) $11,382,000, which was our estimate of reasonably estimable environmental remediation liability, including obligations to remove USTs for which we are responsible, net of estimated recoveries and (b) $36,215,000 for future environmental liabilities related to preexisting unknown contamination. As of December 31, 2020, we had accrued a total of $48,084,000 for our prospective environmental remediation obligations. This accrual consisted of (a) $11,718,000, which was our estimate of reasonably estimable environmental remediation liability, including obligations to remove USTs for which we are responsible, net of estimated recoveries and (b) $36,366,000 for future environmental liabilities related to preexisting unknown contamination. Environmental liabilities are accreted for the change in present value due to the passage of time and, accordingly, $1,705,000, $1,841,000 and $2,006,000 of net accretion expense was recorded for the years ended December 31, 2021, 2020 and 2019, respectively, which is included in environmental expenses. In addition, during the years ended December 31, 2021, 2020 and 2019, we recorded credits to environmental expenses aggregating $1,768,000, $3,136,000 and $5,386,000, respectively, where decreases in estimated remediation costs exceeded the depreciated carrying value of previously capitalized asset retirement costs. Environmental expenses also include project management fees, legal fees and environmental litigation accruals. For the years ended December 31, 2021, 2020 and 2019, changes in environmental estimates aggregating, $147,000, $154,000 and $324,000, respectively, were related to properties that were previously disposed of by us. During the years ended December 31, 2021 and 2020, we increased the carrying values of certain of our properties by $3,004,000 and $2,596,000, respectively, due to changes in estimated environmental remediation costs. The recognition and subsequent changes in estimates in environmental liabilities and the increase or decrease in carrying values of the properties are non-cash transactions which do not appear on our consolidated statements of cash flows. Capitalized asset retirement costs are being depreciated over the estimated remaining life of the UST, a 10-year period if the increase in carrying value is related to environmental remediation obligations or such shorter period if circumstances warrant, such as the remaining lease term for properties we lease from others. Depreciation and amortization expense related to capitalized asset retirement costs in our consolidated statements of operations for the years ended December 31, 2021, 2020 and 2019, were $4,004,000, $4,020,000 and $4,132,000, respectively. Capitalized asset retirement costs were $39,670,000 (consisting of $24,075,000 of known environmental liabilities and $15,595,000 of reserves for future environmental liabilities) as of December 31, 2021, and $39,610,000 (consisting of $23,573,000 of known environmental liabilities and $16,037,000 of reserves for future environmental liabilities) as of December 31, 2020 . We recorded impairment charges aggregating $ and $ for the years ended December 31, 2021 and 2020 , respectively, for capitalized asset retirement costs . Environmental exposures are difficult to assess and estimate for numerous reasons, including the amount of data available upon initial assessment of contamination, alternative treatment methods that may be applied, location of the property which subjects it to differing local laws and regulations and their interpretations, changes in costs associated with environmental remediation services and equipment, the availability of state UST remediation funds and the possibility of existing legal claims giving rise to allocation of responsibilities to others, as well as the time it takes to remediate contamination and receive regulatory approval. In developing our liability for estimated environmental remediation obligations on a property by property basis, we consider, among other things, laws and regulations, assessments of contamination and surrounding geology, quality of information available, currently available technologies for treatment, alternative methods of remediation and prior experience. Environmental accruals are based on estimates derived upon facts known to us at this time, which are subject to significant change as circumstances change, and as environmental contingencies become more clearly defined and reasonably estimable. Any changes to our estimates or our assumptions that form the basis of our estimates may result in our providing an accrual, or adjustments to the amounts recorded, for environmental remediation liabilities. In July 2012, we purchased a 10-year pollution legal liability insurance policy covering substantially all of our properties at that time for preexisting unknown environmental liabilities and new environmental events. The policy has a $50,000,000 aggregate limit and is subject to various self-insured retentions and other conditions and limitations. Our intention in purchasing this policy was to obtain protection predominantly for significant events. In addition to the environmental insurance policy purchased by the Company, we also took assignment of certain environmental insurance policies, and rights to reimbursement for claims made thereunder, from Marketing, by order of the U.S. Bankruptcy Court during Marketing’s bankruptcy proceedings. Under these assigned polices, we have received and expect to continue to receive reimbursement of certain remediation expenses for covered claims. In light of the uncertainties associated with environmental expenditure contingencies, we are unable to estimate ranges in excess of the amount accrued with any certainty; however, we believe that it is possible that the fair value of future actual net expenditures could be substantially higher than amounts currently recorded by us. Adjustments to accrued liabilities for environmental remediation obligations will be reflected in our consolidated financial statements as they become probable and a reasonable estimate of fair value can be made.

Income Taxes	NOTE 6. — INCOME TAXES Net cash paid for income taxes for the years ended December 31, 2021, 2020 and 2019, of $355,000, $350,000 and $304,000, respectively, includes amounts related to state and local income taxes for jurisdictions that do not follow the federal tax rules, which are provided for in property costs in our consolidated statements of operations. Earnings and profits (as defined in the Internal Revenue Code) are used to determine the tax attributes of dividends paid to stockholders and will differ from income reported for consolidated financial statements purposes due to the effect of items which are reported for income tax purposes in years different from that in which they are recorded for consolidated financial statements purposes. The federal tax attributes of the common dividends for the years ended December 31, 2021, 2020 and 2019, were: ordinary income of 73.0%, 88.7% and 96.6%, capital gain distributions of 5.5%, 3.4% and 3.4% and non-taxable distributions of 21.5%, 7.9% and 0.0%, respectively. To qualify for taxation as a REIT, we, among other requirements such as those related to the composition of our assets and gross income, must distribute annually to our stockholders at least 90% of our taxable income, including taxable income that is accrued by us without a corresponding receipt of cash. We cannot provide any assurance that our cash flows will permit us to continue paying cash dividends. Should the Internal Revenue Service successfully assert that our earnings and profits were greater than the amount distributed, we may fail to qualify as a REIT; however, we may avoid losing our REIT status by paying a deficiency dividend to eliminate any remaining earnings and profits. We may have to borrow money or sell assets to pay such a deficiency dividend. Although tax returns for the years 2018, 2019 and 2020, and tax returns which will be filed for the year ended 2021, remain open to examination by federal and state tax jurisdictions under the respective statute of limitations, we have not currently identified any uncertain tax positions related to those years and, accordingly, have not accrued for uncertain tax positions as of December 31, 2021 or 2020. However, uncertain tax matters may have a significant impact on the results of operations for any single fiscal year or interim period.

On March 1, 2020, and December 14, 2020, our Board of Directors granted 176,050 and 15,000 of RSUs under our Amended and Restated 2004 Omnibus Incentive Compensation Plan. ATM Program In March 2018, we established an at-the-market equity offering program (the “2018 ATM Program”), pursuant to which we are able to issue and sell shares of our common stock with an aggregate sales price of up to $125,000,000 through a consortium of banks acting as agents. The 2018 ATM Program was terminated in January 2021. In February 2021, we established a new at-the-market equity offering program (the “ATM Program”), pursuant to which we are able to issue and sell shares of our common stock with an aggregate sales price of up to $250,000,000 through a consortium of banks acting as agents. Sales of the shares of common stock may be made, as needed, from time to time in at-the-market offerings as defined in Rule 415 of the Securities Act, including by means of ordinary brokers’ transactions on the New York Stock Exchange or otherwise at market prices prevailing at the time of sale, at prices related to prevailing market prices or as otherwise agreed to with the applicable agent. In connection with the expansion of the ATM Program, we may also sell shares of common stock under forward sale agreements. The use of a forward sale agreement would allow us to lock in a price on the sale of shares of common stock at the time the agreement is executed, but defer receiving the proceeds from the sale until a later date. During the years ended December 31, 2021 and 2020, we issued 3,043,000 and 2,208,000 shares of common stock and received net proceeds of $92,285,000 and $63,187,000, respectively, under the 2018 ATM Program and ATM Program. Future sales, if any, will depend on a variety of factors to be determined by us from time to time, including among others, market conditions, the trading price of our common stock, determinations by us of the appropriate sources of funding for us and potential uses of funding available to us. We have not entered into any forward sale agreements. Dividends For the year ended December 31, 2021, we paid regular quarterly dividends of $70,770,000 or $1.56 per share. For the year ended December 31, 2020, we paid regular quarterly dividends of $62,626,000 or $1.48 per share. Dividend Reinvestment Plan Our dividend reinvestment plan provides our common stockholders with a convenient and economical method of acquiring additional shares of common stock by reinvesting all or a portion of their dividend distributions. During the years ended December 31, 2021 and 2020, we issued 2,681 and 14,229 shares of common stock, respectively, under the dividend reinvestment plan and received proceeds of $80,000 and $443,000, respectively. Stock-Based Compensation Compensation cost for our stock-based compensation plans using the fair value method was $3,997,000, $3,130,000 and $2,468,000 for the years ended December 31, 2021, 2020 and 2019, respectively, and is included in general and administrative expense in our consolidated statements of operations.

Postemployment Benefits [Abstract]
Employee Benefit Plans	NOTE 8. — EMPLOYEE BENEFIT PLANS The Getty Realty Corp. 2004 Omnibus Incentive Compensation Plan (the “2004 Plan”) provided for the grant of restricted stock, restricted stock units (“RSUs”), performance awards, dividend equivalents, stock payments and stock awards to all employees and members of the Board of Directors. In May 2014, an Amended and Restated 2004 Omnibus Incentive Compensation Plan (the “Restated Plan”) was approved at our annual meeting of stockholders. The Restated Plan maintained the 2004 Plan’s authorization to grant awards with respect to an aggregate of 1,000,000 shares of common stock, extended the term to May 2019 and increased the aggregate maximum number of shares of common stock that may be subject to awards granted during any calendar year to 100,000. In May 2017, the Second Amended and Restated 2004 Omnibus Incentive Compensation Plan in order to, among other things, (i) increase by 500,000 to a total of 1,500,000 the aggregate number of shares that the Company may issue under awards granted pursuant to the Second Restated Plan; (ii) increase from 100,000 to 200,000 the maximum number of shares that may be subject to awards made in a calendar year to all participants under the Second Restated Plan; and (iii) Third Amended and Restated 2004 Omnibus Incentive Compensation Plan in order to, among other things: (i) increase by 2,500,000, to a total of 4,000,000 the aggregate number of shares that the Company may issue under awards granted pursuant to the Third Restated Plan ; (ii) remove the limit on the maximum number of shares that may be subject to awards made in a calendar year to all participants under the Third Restated Plan ; (iii) include a minimum restriction period of one year for all awards (subject to certain exceptions); (iv) extend the term of the Restated Plan until February 22, 2031. five-year We awarded to employees and directors 196,050, 191,050 and 156,750 RSUs and dividend equivalents in 2021, 2020 and 2019, respectively. RSUs granted before 2009 provide for settlement upon termination of employment with the Company or termination of service from the Board of Directors. RSUs granted in 2009 and thereafter provide for settlement upon the earlier of 10 years after the grant date (or the tenth anniversary of the first vesting date for RSU’s granted in 2016-2018) or termination of employment with the Company. On the settlement date each vested RSU will have a value equal to one share of common stock and may be settled, at the sole discretion of the Compensation Committee, in cash or by the issuance of one share of common stock. The RSUs do not provide voting or other stockholder rights unless and until the RSU is settled for a share of common stock. The RSUs vest starting one year from the date of grant, on a cumulative basis at the annual rate of 20% of the total number of RSUs covered by the award. The dividend equivalents represent the value of the dividends paid per common share multiplied by the number of RSUs covered by the award. For the years ended December 31, 2021, 2020 and 2019, dividend equivalents aggregating approximately $1,485,000, $1,279,000 and $997,000, respectively, were charged against retained earnings when common stock dividends were declared.

Under the terms of these plans, the annual discretionary contributions to the plans are determined by the Compensation Committee of the Board of Directors. Also, under the Retirement Plan, employees may make voluntary contributions and we have elected to match an amount equal to fifty percent of such contributions but in no event more than three percent of the employee’s eligible compensation. Under the Supplemental Plan, a participating executive may receive an amount equal to 10 percent of eligible compensation, reduced by the amount of any contributions allocated to such executive under the Retirement Plan. Contributions, net of forfeitures, under the retirement plans approximated $379,000, $353,000 and $327,000 for the years ended December 31, 2021, 2020 and 2019, respectively.

Earnings Per Share [Abstract]
Earnings Per Common Share	NOTE 9. — EARNINGS PER COMMON SHARE Basic and diluted earnings per common share gives effect, utilizing the two-class method, to the potential dilution from the issuance of shares of our common stock in settlement of RSUs which provide for non-forfeitable dividend equivalents equal to the dividends declared per common share. Basic and diluted earnings per common share is computed by dividing net earnings less dividend equivalents attributable to RSUs by the weighted average number of common shares outstanding during the year. Diluted earnings per common share, also gives effect to the potential dilution from the exercise of stock options utilizing the treasury stock method. There were no options outstanding as of December 31, 2021, 2020 and 2019. The following table is a reconciliation of the numerator and denominator used in the computation of basic and diluted earnings per common share using the two-class method (in thousands except per share data): Year ended December 31, (in thousands): 2021 2020 2019 Net earnings $ 62,860 $ 69,388 $ 49,723 Less dividend equivalents attributable to RSUs outstanding (1,437 ) (1,355 ) (997 ) Net earnings attributable to common stockholders used in basic and diluted earnings per share calculation 61,423 68,033 48,726 Weighted average common shares outstanding: Basic 44,782 42,040 41,072 Incremental shares from stock-based compensation 37 30 38 Diluted 44,819 42,070 41,110 Basic earnings per common share $ 1.37 $ 1.62 $ 1.19 Diluted earnings per common share $ 1.37 $ 1.62 $ 1.19

Fair Value Measurements	NOTE 10. — FAIR VALUE MEASUREMENTS Debt Instruments As of December 31, 2021 and 2020, the carrying value of the borrowings under the Second Restated Credit Agreement approximated fair value. As of December 31, 2021 and 2020, the fair value of the borrowings under senior unsecured notes was $561,600,000 and $549,800,000, respectively. The fair value of the borrowings outstanding as of December 31, 2021 and 2020, was determined using a discounted cash flow technique that incorporates a market interest yield curve with adjustments for duration, risk profile and borrowings outstanding, which are based on unobservable inputs within Level 3 of the Fair Value Hierarchy. Supplemental Retirement Plan We have mutual fund assets that are measured at fair value on a recurring basis using Level 1 inputs. We have a Supplemental Retirement Plan for executives. The amounts held in trust under the Supplemental Retirement Plan using Level 2 inputs may be used to satisfy claims of general creditors in the event of our or any of our subsidiaries’ bankruptcy. We have liability to the executives participating in the Supplemental Retirement Plan for the participant account balances equal to the aggregate of the amount invested at the executives’ direction and the income earned in such mutual funds. The following summarizes as of December 31, 2021, our assets and liabilities measured at fair value on a recurring basis by level within the Fair Value Hierarchy (in thousands): Level 1 Level 2 Level 3 Total Assets: Mutual funds $ 1,168 $ — $ — $ 1,168 Liabilities: Deferred compensation $ — $ 1,168 $ — $ 1,168 The following summarizes as of December 31, 2020, our assets and liabilities measured at fair value on a recurring basis by level within the Fair Value Hierarchy (in thousands): Level 1 Level 2 Level 3 Total Assets: Mutual funds $ 970 $ — $ — $ 970 Liabilities: Deferred compensation $ — $ 970 $ — $ 970 Real Estate Assets We have certain real estate assets that are measured at fair value on a non-recurring basis using Level 3 inputs as of December 31, 2021 and 2020, of $1,102,000 and $1,979,000, respectively, where impairment charges have been recorded. Due to the subjectivity inherent in the internal valuation techniques used in estimating fair value, the amounts realized from the sale of such assets may vary significantly from these estimates.

We adopted ASU 2016-13 on January 1, 2020 using the modified retrospective method, under which we recorded a cumulative-effect adjustment as a charge to retained earnings of $309,000. In addition, during the years ended December 31, 202 1 and 2020, we recorded a credit and a n additional allowance for credit losses of $ 40,000 and $ 28,000 , respectively, on these notes and mortgages receivable due to changes in expected economic conditions.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The consolidated financial statements include the accounts of Getty Realty Corp. and its wholly-owned subsidiaries. The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). We do not distinguish our principal business or our operations on a geographical basis for purposes of measuring performance. We manage and evaluate our operations as a single segment. All significant intercompany accounts and transactions have been eliminated.
Use of Estimates, Judgments and Assumptions	Use of Estimates, Judgments and Assumptions The consolidated financial statements have been prepared in conformity with GAAP, which requires management to make estimates, judgments 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 revenues and expenses during the period reported. Estimates, judgments and assumptions underlying the accompanying consolidated financial statements include, but are not limited to, real estate, receivables, deferred rent receivable, direct financing leases, depreciation and amortization, impairment of long-lived assets, environmental remediation costs, environmental remediation obligations, litigation, accrued liabilities, income taxes and the allocation of the purchase price of properties acquired to the assets acquired and liabilities assumed. Application of these estimates and assumptions requires exercise of judgment as to future uncertainties and, as a result, actual results could differ materially from these estimates.
Reclassifications	Reclassifications Certain prior year amounts have been reclassified to conform to current year presentation. Such reclassifications had no impact on previously reported net earnings.
Real Estate	Real Estate Real estate assets are stated at cost less accumulated depreciation and amortization. For acquisitions of real estate we estimate the fair value of acquired tangible assets (consisting of land, buildings and improvements) “as if vacant” and identified intangible assets and liabilities (consisting of leasehold interests, above-market and below-market leases, in-place leases and tenant relationships) and assumed debt. Based on these estimates, we allocate the estimated fair value to the applicable assets and liabilities. Fair value is determined based on an exit price approach, which contemplates the price that would be received from the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assumptions used are property and geographic specific and may include, among other things, capitalization rates, market rental rates, discount rates and EBITDA to rent coverage ratios. We expense transaction costs associated with business combinations in the period incurred. Acquisitions of real estate which do not meet the definition of a business are accounted for as asset acquisitions. The accounting model for asset acquisitions is similar to the accounting model for business combinations except that the acquisition costs are capitalized and allocated to the individual assets acquired and liabilities assumed on a relative fair value basis. For additional information regarding property acquisitions, see Note 13 – Property Acquisitions. We capitalize direct costs, including costs such as construction costs and professional services, and indirect costs associated with the development and construction of real estate assets while substantive activities are ongoing to prepare the assets for their intended use. The capitalization period begins when development activities are underway and ends when it is determined that the asset is substantially complete and ready for its intended use. We evaluate the held for sale classification of our real estate as of the end of each quarter. Assets that are classified as held for sale are recorded at the lower of their carrying amount or fair value less costs to sell. When real estate assets are sold or retired, the cost and related accumulated depreciation and amortization is eliminated from the respective accounts and any gain or loss is credited or charged to income. We evaluate real estate sale transactions where we provide seller financing to determine sale and gain recognition in accordance with GAAP. Expenditures for maintenance and repairs are charged to income when incurred.
Depreciation and Amortization	Depreciation and Amortization Depreciation of real estate is computed on the straight-line method based upon the estimated useful lives of the assets, which generally range from 16 to 25 years for buildings and improvements, or the term of the lease if shorter. Asset retirement costs are depreciated over the shorter of the remaining useful lives of USTs or 10 years for asset retirement costs related to environmental remediation obligations, which costs are attributable to the group of assets identified at a property. Leasehold interests and in-place leases are amortized over the remaining term of the underlying lease.
Direct Financing Leases	Direct Financing Leases Income under direct financing leases is included in revenues from rental properties and is recognized over the lease terms using the effective interest rate method which produces a constant periodic rate of return on the net investments in the leased properties. The investments in direct financing leases are increased for interest income earned and amortized over the life of the leases and reduced by the receipt of lease payments. We consider direct financing leases to be past-due or delinquent when a contractually required payment is not remitted in accordance with the provisions of the underlying agreement. On June 16, 2016, the Financial Accounting Standards Board (the “FASB”) issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurements of Credit Losses on Financial Instruments The accounting standard became effective for us and was adopted on January 1, 2020. Upon adoption, we had five unitary leases subject to this standard classified as a direct financing leases with a net investment balance aggregating $82,366,000 prior to the credit loss adjustment. In these direct financing leases, the payment obligations of the lessees are collateralized by real estate properties. Historically, we have had no collection issues related to these direct financing leases; therefore, we assessed the probability of default on these leases based on the lessee’s financial condition, business prospects, remaining term of the lease, expected value of the underlying collateral upon its repossession, and our historical loss experience related to other leases in which we are the lessor. Based on the aforementioned considerations, we estimated a credit loss reserve related to these direct financing leases totaling $578,000, which was recognized as a cumulative adjustment to retained earnings and as a reduction of the investment in direct financing leases balance on our consolidated balance sheets on January 1, 2020. Periods prior to the adoption date that are presented for comparative purposes were not adjusted. During the year ended December 31, 2020, we recorded an allowance for credit losses of $340,000 on our net investments in direct financing leases due to changes in expected economic conditions, which was included within other income in our consolidated statements of operations. In addition, during the year ended December 31, 2021, we reduced our allowance for credit losses by $92,000 on our net investments in direct financing leases due to changes in expected economic conditions, which was included within other income in our consolidated statements of operations. We review our direct financing leases each reporting period to determine adjust the allowance for any estimated changes in the credit loss with the resulting change recorded through our consolidated statement of operations. When we enter into a contract to sell properties that are recorded as direct financing leases, we evaluate whether we believe that it is probable that the disposition will occur. If we determine that the disposition is probable and therefore the property’s holding period is reduced, we record an allowance for credit losses to reflect the change in the estimate of the undiscounted future rents. Accordingly, the net investment balance is written down to fair value.
Notes and Mortgages Receivable	Notes and Mortgages Receivable Notes and mortgages receivable consists of loans originated by us in conjunction with property dispositions and funding provided to tenants in conjunction with property acquisitions and capital improvements. Notes and mortgages receivable are recorded at stated principal amounts. In conjunction with our adoption of ASU 2016-13 on January 1, 2020, we which was recognized as a cumulative adjustment to retained earnings and as a reduction of the on the notes and mortgages receivable balance on our consolidated balance sheets on January 1, 2020. Periods prior to the adoption date that are presented for comparative purposes were not adjusted. During the year ended December 31, 2020, we recorded an additional allowance for credit losses of $28,000 on these notes and mortgages receivable due to changes in expected economic conditions, which was included within o ther income in our consolidated statements of operations. In addition, during the year ended December 31, 2021, we redu ced our allowance for credit losses by $ 40,000 on these notes and mortgages receivable due to changes in expected economic conditions, which was included within other income in our consolidated statements of operations From time to time, we may originate construction loans for the construction of income-producing properties. $13.5 million. During the year ended December 31, 2021, we exercised our option to purchase two properties for $10.0 million for which we had previously funded construction loans in the amount of $7.8 million, at which time the loans were repaid in full At there were $ million of outstanding balances for construction loans. Our construction loans generally provide for funding only during the construction phase, which is typically up to nine months, although our policy is to consider construction periods as long as 24 months. Funds are disbursed based on inspections in accordance with a schedule reflecting the completion of portions of the project. We also review and inspect each property before disbursement of funds during the term of the construction loan. At the end of the construction phase, the construction loan will be repaid with the proceeds from the sale of the property. We have the option to purchase the property at the end of the construction period.
Cash and Cash Equivalents	Cash and Cash Equivalents We consider all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. Our cash and cash equivalents are held in the custody of financial institutions, and these balances, at times, may exceed federally insurable limits.
Restricted Cash	Restricted Cash Restricted cash consists of cash that is contractually restricted or held in escrow pursuant to various agreements with counterparties. At December 31, 2021 and 2020, restricted cash of $1,723,000 and $1,979,000, respectively, consisted of security deposits received from our tenants.
Revenue Recognition and Deferred Rent Receivable	Revenue Recognition and Deferred Rent Receivable On January 1, 2018, we adopted ASU 2014-09, Revenue from Contracts with Customers (Topic 606), (“Topic 606”) using the modified retrospective method applying it to any open contracts as of January 1, 2018. The new guidance provides a unified model to determine how revenue is recognized. To determine the proper amount of revenue to be recognized, we perform the following steps: (i) identify the contract with the customer, (ii) identify the performance obligations within the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations and (v) recognize revenue when (or as) a performance obligation is satisfied. Our primary source of revenue consists of revenue from rental properties and tenant reimbursements that is derived from leasing arrangements, which is specifically excluded from the standard, and thus had no material impact on our consolidated financial statements or notes to our consolidated financial statements as of December 31, 2021, 2020 and 2019. Lease payments from operating leases are recognized on a straight-line basis over the term of the leases. The cumulative difference between lease revenue recognized under this method and the contractual lease payment terms is recorded as deferred rent receivable on our consolidated balance sheets. We review our accounts receivable, including its deferred rent receivable, related to base rents, straight-line rents, tenant reimbursements and other revenues for collectability. Our evaluation of collectability primarily consists of reviewing past due account balances and considers such factors as the credit quality of our tenant, historical trends of the tenant, changes in tenant payment terms, current economic trends, including the novel coronavirus (“COVID-19”) pandemic, and other facts and circumstances related to the applicable tenants. In addition, with respect to tenants in bankruptcy, we estimate the probable recovery through bankruptcy claims. If a tenant’s accounts receivable balance is considered uncollectable, we will write off the related receivable balances and cease to recognize lease income, including straight-line rent unless cash is received. If the collectability assessment subsequently changes to probable, any difference between the lease income that would have been recognized if collectability had always been assessed as probable and the lease income recognized to date, is recognized as a current-period adjustment to revenues from rental properties. Our reported net earnings are directly affected by our estimate of the collectability of our accounts receivable. In April 2020, the FASB issued interpretive guidance relating to the accounting for lease concessions provided as a result of COVID-19. In this guidance, entities can elect not to apply lease modification accounting with respect to such lease concessions and instead, treat the concession as if it was a part of the existing contract. This guidance is only applicable to COVID-19 related lease concessions that do not result in a substantial increase in the rights of the lessor or the obligations of the lessee. Some concessions will provide a deferral of payments with no substantive changes to the consideration in the original contract. A deferral affects the timing of cash receipts, but the amount of the consideration is substantially the same as that required by the original contract. The FASB staff provides two ways to account for those deferrals: (1) Account for the concessions as if no changes to the lease contract were made. Under that accounting, a lessor would increase its lease receivable. In its income statement, a lessor would continue to recognize income during the deferral period. (2) Account for the deferred payments as variable lease payments. We elected to treat lease concessions with option (1) above for the year ended December 31, 2021. There were no outstanding balances for lease concessions provided as a result of COVID-19 at December 31, 2021. The present value of the difference between the fair market rent and the contractual rent for above-market and below-market leases at the time properties are acquired is amortized into revenues from rental properties over the remaining terms of the in-place leases. Lease termination fees are recognized as other income when earned upon the termination of a tenant’s lease and relinquishment of space in which we have no further obligation to the tenant. The sales of nonfinancial assets, such as real estate, are to be recognized when control of the asset transfers to the buyer, which will occur when the buyer has the ability to direct the use of or obtain substantially all of the remaining benefits from the asset. This generally occurs when the transaction closes and consideration is exchanged for control of the property.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets Assets are written down to fair value when events and circumstances indicate that the assets might be impaired and the projected undiscounted cash flows estimated to be generated by those assets are less than the carrying amount of those assets. Assets held for disposal are written down to fair value less estimated disposition costs. We recorded impairment charges aggregating $4,404,000, $4,258,000 and $4,012,000 for the years ended December 31, 2021, 2020 and 2019, respectively. Our estimated fair values, as they relate to property carrying values, were primarily based upon (i) estimated sales prices from third-party offers based on signed contracts, letters of intent or indicative bids, for which we do not have access to the unobservable inputs used to determine these estimated fair values, and/or consideration of the amount that currently would be required to replace the asset, as adjusted for obsolescence (this method was used to determine $964,000 of the $4,404,000 in impairments recognized during the year ended December 31, 2021) and (ii) discounted cash flow models (this method was used to determine $484,000 of the $4,404,000 in impairments recognized during the year ended December 31, 2021). During the year ended December 31, 2021, we recorded the remaining impairments of $2,956,000 of the $4,404,000 due to the accumulation of asset retirement costs as a result of changes in estimates associated with our estimated environmental liabilities which increased the carrying values of certain properties in excess of their fair values. For the years ended December 31, 2021, 2020 and 2019, impairment charges aggregating $919,000, $932,000 and $1,202,000, respectively, were related to properties that were previously disposed of by us. The estimated fair value of real estate is based on the price that would be received from the sale of the property in an orderly transaction between market participants at the measurement date. In general, we consider multiple internal valuation techniques when measuring the fair value of a property, all of which are based on unobservable inputs and assumptions that are classified within Level 3 of the Fair Value Hierarchy. These unobservable inputs include assumed holding periods ranging up to 15 years, assumed average rent increases of 2.0% annually, income capitalized at a rate of 8.0% and cash flows discounted at a rate of 7.0%. These assessments have a direct impact on our net income because recording an impairment loss results in an immediate negative adjustment to net income. The evaluation of anticipated cash flows is highly subjective and is based in part on assumptions regarding future rental rates and operating expenses that could differ materially from actual results in future periods. Where properties held for use have been identified as having a potential for sale, additional judgments are required related to the determination as to the appropriate period over which the projected undiscounted cash flows should include the operating cash flows and the amount included as the estimated residual value. This requires significant judgment. In some cases, the results of whether impairment is indicated are sensitive to changes in assumptions input into the estimates, including the holding period until expected sale.
Fair Value of Financial Instruments	Fair Value of Financial Instruments All of our financial instruments are reflected in the accompanying consolidated balance sheets at amounts which, in our estimation based upon an interpretation of available market information and valuation methodologies, reasonably approximate their fair values, except those separately disclosed in the notes below. The preparation of consolidated financial statements in accordance with GAAP requires management to make estimates of fair value that affect the reported amounts of assets and liabilities and disclosure of assets and liabilities at the date of the consolidated financial statements and revenues and expenses during the period reported using a hierarchy (the “Fair Value Hierarchy”) that prioritizes the inputs to valuation techniques used to measure the fair value. The Fair Value Hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The levels of the Fair Value Hierarchy are as follows: “Level 1” – inputs that reflect unadjusted quoted prices in active markets for identical assets or liabilities that we have the ability to access at the measurement date; “Level 2” – inputs other than quoted prices that are observable for the asset or liability either directly or indirectly, including inputs in markets that are not considered to be active; and “Level 3” – inputs that are unobservable. Certain types of assets and liabilities are recorded at fair value either on a recurring or non-recurring basis. Assets required or elected to be marked-to-market and reported at fair value every reporting period are valued on a recurring basis. Other assets not required to be recorded at fair value every period may be recorded at fair value if a specific provision or other impairment is recorded within the period to mark the carrying value of the asset to market as of the reporting date. Such assets are valued on a non-recurring basis.
Environmental Remediation Obligations	Environmental Remediation Obligations We record the fair value of a liability for an environmental remediation obligation as an asset and liability when there is a legal obligation associated with the retirement of a tangible long-lived asset and the liability can be reasonably estimated. Environmental remediation obligations are estimated based on the level and impact of contamination at each property. The accrued liability is the aggregate of our estimate of the fair value of cost for each component of the liability. The accrued liability is net of estimated recoveries from state UST remediation funds considering estimated recovery rates developed from prior experience with the funds. Net environmental liabilities are currently measured based on their expected future cash flows which have been adjusted for inflation and discounted to present value. We accrue for environmental liabilities that we believe are allocable to other potentially responsible parties if it becomes probable that the other parties will not pay their environmental remediation obligations.
Litigation	Litigation Legal fees related to litigation are expensed as legal services are performed. We provide for litigation accruals, including certain litigation related to environmental matters, when it is probable that a liability has been incurred and a reasonable estimate of the liability can be made. If the estimate of the liability can only be identified as a range, and no amount within the range is a better estimate than any other amount, the minimum of the range is accrued for the liability. We accrue our share of environmental litigation liabilities based on our assumptions of the ultimate allocation method and share that will be used when determining our share of responsibility.
Income Taxes	Income Taxes We file a federal income tax return on which are consolidated our tax items and the tax items of our subsidiaries that are pass-through entities. Effective January 1, 2001, we elected to qualify, and believe that we are operating so as to qualify, as a REIT for federal income tax purposes. Accordingly, we generally will not be subject to federal income tax on qualifying REIT income, provided that distributions to our stockholders equal at least the amount of our taxable income as defined under the Internal Revenue Code. We accrue for uncertain tax matters when appropriate. The accrual for uncertain tax positions is adjusted as circumstances change and as the uncertainties become more clearly defined, such as when audits are settled or exposures expire. Tax returns for the years 2018, 2019 and 2020, and tax returns which will be filed for the year ended 2021, remain open to examination by federal and state tax jurisdictions under the respective statutes of limitations.
New Accounting Pronouncements	New Accounting Pronouncements On March 12, 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) (“ASU 2020-04”). ASU 2020-04 contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. The guidance in ASU 2020-04 provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. We are currently evaluating the impact the adoption of ASU 2020-04 will have on our consolidated financial statements .
