Principles of Consolidation – NNN’s consolidated financial statements include the accounts of each of the respective majority owned and controlled affiliates, including transactions whereby NNN has been determined to be the primary beneficiary in accordance with the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") guidance included in Consolidation. All significant intercompany account balances and transactions have been eliminated.

NNN consolidates certain joint venture development entities based upon either NNN being the primary beneficiary of the respective variable interest entity or NNN having a controlling interest over the respective entity. NNN records a noncontrolling interest for its non-NNN ownership of consolidated entities.

Real Estate Portfolio – NNN records the acquisition of real estate at cost, including acquisition and closing costs. The cost of Properties developed or funded by NNN includes direct and indirect costs of construction, property taxes, interest and other miscellaneous costs incurred during the development period until the project is substantially complete and available for occupancy. For the years ended December 31, 2022, 2021 and 2020, NNN recorded $881,000, $328,000 and $1,388,000, respectively, in capitalized interest during development.

Purchase Accounting for Acquisition of Real Estate – In accordance with the FASB guidance on business combinations, consideration for the real estate acquired is allocated to the acquired tangible assets, consisting of land, building and tenant improvements and, if applicable, to identified intangible assets and liabilities, consisting of the value of above-market and below-market leases and the value of in-place leases, as applicable, based on their respective fair values.

The fair value estimate is sensitive to significant assumptions, such as establishing a range of relevant market assumptions for land, building and rent and where the acquired property falls within that range. These market assumptions for land, building and rent use the most relevant comparable properties for an acquisition. The final value relies upon ranking comparable properties' attributes from most to least similar.

The fair value of the tangible assets of an acquired property is determined by valuing the property as if it were vacant, and the "as-if-vacant" value is then allocated to land, building and tenant improvements based on the determination of their fair values.

In allocating the fair value of the identified intangible assets and liabilities of an acquired property, above-market and below-market in-place lease values are recorded as other assets or liabilities based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases, and (ii) management’s estimate of fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining term of the lease and the renewal option terms if it is probable that the tenant will exercise options. The capitalized above-market lease values are amortized as a reduction of rental income over the remaining terms of the respective leases. The capitalized below-market lease values are amortized as an increase to rental income over the initial term unless the Company believes that it is likely that the tenant will renew the lease for an option term whereby the Company amortizes the value attributable to the renewal over the renewal period.

The aggregate value of other acquired intangible assets, consisting of in-place leases, is valued by comparing the purchase price paid for a property after adjusting for existing in-place leases to the estimated fair value of the property as-if-vacant, determined as set forth above. This intangible asset is amortized to expense over the remaining non-cancelable periods of the respective leases. If a lease were to be terminated prior to its stated expiration, all unamortized amounts relating to that lease would be written off in that period. The value of tenant relationships is reviewed on individual transactions to determine if future value was derived from the acquisition.

NNN completed $784,165,000 and $531,726,000 of real estate acquisitions during the year ended December 31, 2022 and 2021, respectively. Additionally, NNN invested $63,582,000 and $23,689,000 of work in progress and improvements during the year ended December 31, 2022 and 2021, respectively.

Lease Accounting – NNN records its leases on the Property Portfolio in accordance with FASB Accounting Standards Update ("ASU") 2016-02, "Leases (Topic 842)," ("ASC 842"). In addition, NNN records right-of-use assets and operating lease liabilities as lessee under operating leases in accordance with ASC 842.

NNN's real estate is generally leased to tenants on a net lease basis, whereby the tenant is responsible for all operating expenses relating to the Property, including property taxes, insurance, maintenance, repairs and capital expenditures. The leases are accounted for using either the operating or the direct financing method. Such methods are described below:

Operating method – Properties with leases accounted for using the operating method are recorded at the cost of the real estate and depreciated on the straight-line method over their estimated remaining useful lives, which generally range from 20 to 40 years for buildings and improvements and 15 years for land improvements. Leasehold interests are amortized on the straight-line method over the terms of their respective leases. Revenue is recognized as rentals are earned and expenses (including depreciation) are charged to operations as incurred. When scheduled rentals vary during the lease term, income is recognized on a straight-line basis so as to produce a constant periodic rent over the term of the lease. Accrued rental income is the aggregate difference between the scheduled rents which vary during the lease term and the income recognized on a straight-line basis.

Direct financing method – Properties with leases accounted for using the direct financing method are recorded at their net investment (which at the inception of the lease generally represents the cost of the Property). Unearned income is deferred and amortized into income over the lease terms so as to produce a constant periodic rate of return on NNN’s net investment in the leases.

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. NNN elected to make this policy election for COVID-19 lease concessions, provided in the rent deferral lease amendments effective during the years ended December 31, 2021 and 2020.

Collectability – In accordance with ASC 842, NNN reviews the collectability of its lease payments on an ongoing basis. NNN considers collectability indicators when analyzing accounts receivable (and accrued rent) and historical bad debt levels, tenant credit-worthiness and current economic trends, all of which assists in evaluating the probability of outstanding and future rental income collections. In addition, tenants in bankruptcy are analyzed and considerations are made in connection with the expected recovery of pre-petition and post-petition bankruptcy claims.

When NNN deems the collection of rental income from a tenant not probable, uncollected previously recognized rental revenue and any related accrued rent are reversed as a reduction to rental income and, subsequently, any rental income is only recognized when cash receipts are received. At this point, a tenant is deemed cash basis for accounting purposes.

As a result of the review of lease payments collectability, NNN recorded a write-off of $21,792,000 of outstanding receivables and related accrued rent during the year ended December 31, 2020, and reclassified certain tenants as cash basis for accounting purposes. During the years ended December 31, 2022 and 2021, no additional tenants were deemed as cash basis for accounting purposes.

During the years ended December 31, 2022, 2021 and 2020, NNN recognized $62,454,000, $52,129,000 and $4,722,000, respectively, of rental income from certain tenants for periods following their classification to cash basis for accounting purposes.

During the year ended December 31, 2022, three tenants were reclassified to accrual basis for accounting purposes due to their improved qualitative and/or quantitative credit factors. The impact of the reclassification was immaterial.

NNN includes an allowance for doubtful accounts in rental income on the Consolidated Statements of Income and Comprehensive Income.

Right-Of-Use ("ROU") Assets and Operating Lease Liabilities – In accordance with ASC 842, NNN recorded ROU assets and operating lease liabilities as lessee under operating lease.

NNN is a lessee for three ground lease arrangements and for its headquarters office lease. NNN recognized a ROU asset (recorded in other assets on the Consolidated Balance Sheets) and an operating lease liability (recorded in other liabilities on the Consolidated Balance Sheets) for the present value of the minimum lease payments. ROU assets represent NNN’s right to use an underlying asset for the lease term and lease liabilities represent NNN’s obligation to make lease payments arising from the lease. ROU assets and operating lease liabilities are recognized at the lease commencement date based on the estimated present value of the lease payments over the lease term. NNN’s lease term is based on the non-cancellable base term unless economic incentives make it reasonably certain that an option period to extend the lease will be exercised, in which event NNN includes the options.

NNN estimates an incremental borrowing rate, which is derived from information available at the lease commencement date, in determining the present value of the lease payments. NNN gives consideration to the Company's debt issuances, as well as, publicly available data for secured instruments with similar characteristics when calculating its incremental borrowing rates. On an annual basis, NNN will evaluate its lessee portfolio and determine if its incremental borrowing rate should be reassessed.

NNN's lease agreements do not contain any residual value guarantees.

Real Estate – Held For Sale – Real estate held for sale is not depreciated and is recorded at the lower of cost or fair value, less cost to sell. On a quarterly basis, the Company evaluates its Properties for held for sale classification based on specific criteria as outlined in ASC 360, "Property, Plant and Equipment," including management's intent to commit to a plan to sell the asset. NNN anticipates the disposition of Properties classified as held for sale to occur within 12 months. At December 31, 2022 and 2021, NNN had recorded real estate held for sale of $786,000 (two properties) and $5,557,000 (two properties), respectively, in real estate portfolio on the Consolidated Balance Sheets. The two properties classified as held for sale as of December 31, 2021 were sold during the year ended December 31, 2022.

Real Estate Dispositions – When real estate is disposed, the related cost, accumulated depreciation or amortization and any accrued rental income for operating leases and the net investment for direct financing leases are removed from the accounts, and gains and losses from the dispositions are reflected in income. Gains from the disposition of real estate are generally recognized using the full accrual method in accordance with FASB, ASC 610-20, "Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets" ("ASC 610-20"), provided that various criteria relating to the terms of the sale and any subsequent involvement by NNN with the real estate sold are met.

Impairment – Real Estate – NNN periodically assesses its long-lived real estate assets for possible impairment whenever certain events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. These indicators include, but are not limited to: changes in real estate market conditions, the ability of NNN to re-lease properties that are currently vacant or become vacant, properties reclassified as held for sale, persistent vacancies greater than one year, and properties leased to tenants in bankruptcy. Management evaluates whether an impairment in carrying value has occurred by comparing the estimated future cash flows (undiscounted and without interest charges), and the residual value of the real estate, with the carrying value of the individual asset. The future undiscounted cash flows are primarily driven by estimated future market rents. Future cash flow estimates are sensitive to the assumptions made by management regarding future market rents, which are affected by expectations about future market and economic conditions. If an impairment is indicated, a loss will be recorded for the amount by which the carrying value of the asset exceeds its estimated fair value. NNN's Properties are leased primarily to retail tenants under long-term net leases and primarily held for investment. Generally, NNN’s Property leases provide for initial terms of 10 to 20 years, with cash flows provided over the entire term.

Credit Losses on Financial Instruments – Effective January 1, 2020, NNN adopted FASB ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326),” (“ASC 326”). The amendments in this update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates.

ASU 326 requires entities to estimate an expected lifetime credit loss on financial assets ranging from short-term trade accounts receivable to long-term financings. The new guidance requires a lifetime credit loss expected at inception and requires pooling of assets, which share similar risk characteristics. NNN is required to evaluate current economic conditions, as well as, make future expectations of economic conditions. In addition, the measurement of the expected credit loss is over the asset’s contractual term.

NNN held mortgages receivable, including accrued interest, of $1,530,000 and $2,023,000 included in other assets on the Consolidated Balance Sheets as of December 31, 2022 and 2021, respectively, net of $98,000 and $129,000 allowance for credit loss, respectively. NNN measures the allowance for credit loss based on the fair value of the collateral and the historical collectability trend analysis over 15 years.

Adoption of ASC 326 did not materially impact NNN’s financial position or results of operations and had no impact on cash flows.

Cash and Cash Equivalents – NNN considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. Cash and cash equivalents consist of cash and money market accounts. Cash equivalents are stated at cost plus accrued interest, which approximates fair value.

Cash accounts maintained on behalf of NNN in demand deposits at commercial banks and money market funds may exceed federally insured levels or may be held in accounts without any federal insurance or any other insurance or guarantee. However, NNN has not experienced any losses in such accounts.

Restricted Cash and Cash Held in Escrow – Restricted cash and cash held in escrow include (i) cash proceeds from the sale of assets held by qualified intermediaries in anticipation of the acquisition of replacement properties in tax-free exchanges under Section 1031 of the Internal Revenue Code of 1986, as amended (the "Code"), (ii) cash that has been placed in escrow for the future funding of construction commitments, or (iii) cash that is not immediately available to NNN. As of December 31, 2022 NNN held $4,273,000 in escrow and other restricted accounts. NNN had no restricted cash or cash held in escrow as of December 31, 2021.

Valuation of Trade Receivables – NNN estimates the collectability of its accounts receivable related to rents, expense reimbursements and other revenues. NNN analyzes accounts receivable and historical bad debt levels, tenant credit-worthiness and current economic trends when evaluating the adequacy of the allowance for doubtful accounts. In addition, tenants in bankruptcy are analyzed and estimates are made in connection with the expected recovery of pre-petition and post-petition claims.

Debt Costs – Line of Credit Payable – Debt costs incurred in connection with NNN’s $1,100,000,000 unsecured revolving line of credit have been deferred and are being amortized to interest expense over the term of the loan commitment using the straight-line method, which approximates the effective interest method. NNN has recorded debt costs associated with the credit facility as an asset, in debt costs on the Consolidated Balance Sheets.

Debt Costs – Mortgages Payable – Debt costs incurred in connection with NNN’s mortgages have been deferred and are being amortized over the term of the respective loan commitment using the straight-line method, which approximates the effective interest method. These costs of $147,000 at December 31, 2022 and 2021, are included in mortgages payable on the Consolidated Balance Sheets net of accumulated amortization of $142,000 and $125,000, respectively.

Debt Costs – Notes Payable – Debt costs incurred in connection with the issuance of NNN’s unsecured notes have been deferred and are being amortized to interest expense over the term of the respective debt obligation using the effective interest method. These costs of $38,145,000 at December 31, 2022 and 2021, respectively are included in notes payable on the Consolidated Balance Sheets net of accumulated amortization of $11,693,000 and $9,262,000, respectively.

Revenue Recognition – Rental revenues for properties under construction commence upon completion of construction of the leased asset and delivery of the leased asset to the tenant. Rental revenues for non-development real estate assets are recognized when earned in accordance with ASC 842, based on the terms of the lease of the leased asset. Lease termination fees are recognized when collected subsequent to the related lease that is cancelled and NNN no longer has continuing involvement with the former tenant with respect to that property.

Earnings Per Share – Earnings per share have been computed pursuant to the FASB guidance included in Earnings Per Share. The guidance requires classification of the Company’s unvested restricted share units which contain rights to receive nonforfeitable dividends, as participating securities requiring the two-class method of computing earnings per share. Under the two-class method, earnings per common share are computed by dividing the sum of distributed earnings to common stockholders and undistributed earnings allocated to common stockholders by the weighted average number of common shares outstanding for the period. In applying the two-class method, undistributed earnings are allocated to both common shares and participating securities based on the weighted average shares outstanding during the period. 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 for the years ended December 31 (dollars in thousands):

Income Taxes – NNN has made an election to be taxed as a REIT under Sections 856 through 860 of the Code, and related regulations. NNN generally will not be subject to federal income taxes on income it distributes to stockholders, providing it distributes 100 percent of its REIT taxable income and meets certain other requirements for qualifying as a REIT. For each of the years in the three-year period ended December 31, 2022, NNN believes it has qualified as a REIT. Notwithstanding NNN’s qualification for taxation as a REIT, NNN is subject to certain state and local income, franchise and excise taxes.

NNN may elect to treat certain subsidiaries as TRS pursuant to the provisions of the REIT Modernization Act. A TRS is able to engage in activities resulting in income that previously would have been disqualified from being eligible REIT income under the federal income tax regulations. As a result, certain activities of NNN which occur within its TRS entities are subject to federal and state or local income taxes. All provisions for federal income taxes in the accompanying consolidated financial statements are attributable to NNN’s former TRS. The deferred tax asset consists only of net operating loss carryforwards of $3,899,000 from the former TRS that begin to expire in 2026. Management believes it is unlikely that NNN will realize any of the benefits of these deductible differences and has taken a valuation allowance against them. There was no change to the valuation allowance. NNN currently has no TRS entities.

Income taxes are accounted for under the asset and liability method as required by ASC 740, "Income Taxes." Deferred tax assets and liabilities are recognized for the temporary differences based on estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the applicable period.

In accordance with ASC 740, NNN has analyzed its various federal and state filing positions. NNN believes that its income tax filing positions and deductions are well documented and supported. Additionally, NNN believes that its accruals for tax liabilities are adequate. Therefore, no reserves for uncertain income tax positions have been recorded.

NNN has had no unrecognized tax benefits during any of the years presented. Further, no interest or penalties have been included since no reserves were recorded and no significant increases or decreases are expected to occur within the next 12 months. When applicable, such interest and penalties will be recorded in non-operating expenses. The periods that remain open under federal statute are 2019 through 2022. NNN also files in many states and localities with varying open years under statute.

Fair Value Measurement – NNN’s estimates of fair value of financial and non-financial assets and liabilities are based on the framework established in the fair value accounting guidance. The framework specifies a hierarchy of valuation inputs which was established to increase consistency, clarity and comparability in fair value measurements and related disclosures. The guidance describes a fair value hierarchy based upon three levels of inputs that may be used to measure fair value, two of which are considered observable and one that is considered unobservable. The following describes the three levels:

Accumulated Other Comprehensive Income (Loss) – The following table outlines the changes in accumulated other comprehensive income (loss) for the years ended December 31, 2022 and 2021 (dollars in thousands):

New Accounting Pronouncements – ASU 2020-04, Reference Rate Reform (Topic 848) (“ASU 2020-04”) contains practical expedients for reference rate reform-related activities, including the transition away from the London Interbank Offered Rate ("LIBOR"), that impact debt, leases, derivatives and other contracts. The guidance in ASU 2020-04 is optional and may be elected over time as reference rate reform activities occur. In 2021, NNN elected to apply the hedge accounting expedients related to probability and the assessments of effectiveness for future LIBOR-indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. Application of these expedients preserves the presentation of derivatives consistent with past presentation. NNN continues to evaluate the impact of the guidance and may apply other elections as applicable as additional changes in the market occur.

NNN had no derivative financial instruments outstanding as of December 31, 2022.

In December 2022, the FASB issued ASU 2022-06, Deferral of the Sunset Date of Topic 848 (“ASU 2022-06”) which was issued to defer the sunset date of Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform to December 31, 2024. ASU 2022-06 is effective immediately for all companies. For the year ended December 31, 2022, ASU 2022-06 had no impact on NNN's financial position or results of operations.

Use of Estimates – Additional critical accounting policies of NNN include management’s estimates and assumptions relating to the reporting of assets and liabilities, revenues and expenses and the disclosure of contingent assets and liabilities are required to prepare the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America. Significant accounting policies include management’s estimates of the purchase accounting for acquisition of real estate, the recoverability of the carrying value of long-lived assets and management's evaluation of the probability of outstanding and future lease payment collections. Actual results could differ from those estimates.
