Dec. 31, 2024
SIGNIFICANT ACCOUNTING POLICIES |
Principles of Consolidation | Principles of Consolidation ​ The consolidated financial statements include the accounts and operations of OLP, its wholly owned subsidiaries, its joint ventures in which the Company, as defined, has a controlling interest, and variable interest entities (“VIEs”) of which the Company is the primary beneficiary. OLP and its consolidated subsidiaries are referred to herein as the “Company”. Material intercompany items and transactions have been eliminated in consolidation. ​
Use of Estimates | Use of Estimates ​ The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. ​ Management believes that the estimates and assumptions that are most important to the portrayal of the Company’s consolidated financial condition and results of operations, in that they require management’s most difficult, subjective or complex judgments, form the basis of the accounting policies deemed to be most significant to the Company. These significant accounting policies relate to revenues and the value of the Company’s real estate portfolio, including investments in unconsolidated joint ventures. Management believes its estimates and assumptions related to these significant accounting policies are appropriate under the circumstances; however, should future events or occurrences result in unanticipated consequences, there could be a material impact on the Company’s future consolidated financial condition or results of operations. ​
Revenue Recognition | Revenue Recognition ​ Rental income includes the base rent that each tenant is required to pay in accordance with the terms of its lease reported over the non-cancelable term of the lease on a straight-line basis, if collectability is probable. On a quarterly basis, management reviews the tenant’s payment history and financial condition in determining, in its judgment, whether any accrued rental income and unbilled rent receivable balances applicable to a specific tenant is collectable. Any change to the collectability of lease payments or unbilled rent receivables is recognized as a current period adjustment to rental revenue (see Note 3). ​ Some leases provide for increases based on the Consumer Price Index or for additional contingent rental revenue in the form of percentage rents. The percentage rents are based upon the level of sales achieved by the lessee and are recognized once the required sales levels are reached. Some leases provide for an incentive for the lessee to sign a lease, such as a leasehold improvement allowance in which the Company reimburses the tenant for the construction of lessee assets. Such lease incentives are capitalized at lease commencement and recognized on a straight-line basis over the lease term as a reduction to rental income. A ground lease provides for rent which can be deferred and paid based on the operating performance of the property; therefore, this rent is recognized as rental income when the operating performance is achieved and the rent is received. NOTE 2 — SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) ​ Many of the Company’s properties are subject to long-term net leases under which the tenant is typically responsible to pay directly to the vendor the real estate taxes, insurance, utilities and ordinary maintenance and repairs related to the property, and the Company is not the primary obligor with respect to such items. As a result, the revenue and expenses relating to these properties are recorded on a net basis. For certain properties, in addition to contractual base rent, the tenants pay their contractual share of real estate taxes and operating expenses to the Company. The revenue and expenses associated with properties at which the Company is the primary obligor are generally recorded on a gross basis. During 2024, 2023 and 2022, the Company recorded reimbursements of expenses of $14,793,000, $13,636,000 and $12,548,000, respectively, which are included in Rental income, net, in the accompanying consolidated statements of income. ​ Gains and losses on the sale of real estate investments are recorded when the Company no longer holds a controlling financial interest in the entity which holds the real estate investment and the relevant revenue recognition criteria under GAAP have been met. ​
Purchase Accounting for the Acquisition of Real Estate | Purchase Accounting for the Acquisition of Real Estate ​ In acquiring real estate, the Company evaluates whether substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets, and if that requirement is met, the asset group is accounted for as an asset acquisition and not a business combination. Transaction costs incurred with such asset acquisitions are capitalized to real estate assets and depreciated over the respectful useful lives. ​ The Company allocates the purchase price of real estate, including direct transaction costs applicable to an asset acquisition, among land, building, improvements and intangibles (e.g., the value of above, below and at-market leases, origination costs associated with in-place leases and above or below-market mortgages assumed at the acquisition date). The value, as determined, is allocated to the gross assets acquired based on management’s determination of the relative fair values of these assets and liabilities. ​ The Company assesses the fair value of the gross assets acquired based on available market information which utilize estimated cash flow projections; such inputs are categorized as Level 3 inputs in the fair value hierarchy. In determining fair value, factors considered by management include an evaluation of current market demand, market capitalization rates and discount rates, estimates of carrying costs (e.g., real estate taxes, insurance and other operating expenses), and lost rental revenue during the expected lease-up periods. Management also estimates costs to execute similar leases, including leasing commissions and tenant improvements. ​ The values of acquired above-market and below-market leases are recorded based on the present values (using discount rates which reflect the risks associated with the leases acquired) of the difference between the contractual amounts to be received and management’s estimate of market lease rates, measured over the terms of the respective leases that management deemed appropriate at the time of the acquisition. Such valuations include a consideration of the non-cancellable terms of the respective leases, as well as any applicable renewal period(s). The fair values associated with below-market rental renewal options are determined based on the Company’s experience and other relevant factors at the time of the acquisition. The values of above-market leases are amortized as a reduction to rental income over the terms of the respective non-cancellable lease periods. The values of below-market leases are amortized as an increase to rental income over the terms of the respective non-cancellable lease periods. The portion of the values of the leases associated with below-market renewal options that management deemed are reasonably certain to be exercised by the tenant are amortized to rental income over such renewal periods. The value of other intangible assets (i.e., origination costs) is recorded to amortization expense over the remaining term of the respective leases. If a lease is terminated prior to its contractual expiration date or not renewed, all unamortized amounts relating to that lease would be recognized in operations at such time. The estimated remaining useful lives of intangibles assets or liabilities range from approximately one to 28 years. NOTE 2 — SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) ​ The values of assumed mortgages are recorded based on the present values (using discount rates which reflect the risks associated with the mortgage assumed) of the difference between the contractual amounts to be paid at the stated interest rates and management’s estimate of market interest rates for similar debt, at the time of the acquisition, measured over the term of such debt. The values of above or below-market mortgages are amortized as a decrease or increase, respectively, to interest expense over the term of the respective debt. The estimated remaining useful lives of intangible mortgage assets range from approximately four to five years.
Accounting for Long-Lived Assets and Impairment of Real Estate Owned | Accounting for Long-Lived Assets and Impairment of Real Estate Owned ​ The Company reviews its real estate portfolio on a quarterly basis for indicators of impairment to the value of any of its real estate assets, including deferred costs and intangibles, to determine if there is any need for an impairment charge. In reviewing the portfolio, the Company examines one or more of the following: the type of asset, the current financial statements or other available financial information of the tenant, prolonged or significant vacancies, the economic environment of the area in which the asset is located and the industry in which the tenant is involved, the timeliness of the payments made by the tenant under its lease, property inspection reports and communication with, by, or relating to, the tenant. For each real estate asset owned for which indicators of impairment exist, management performs a recoverability test by comparing (i) the sum of the estimated undiscounted future cash flows attributable to the asset, which are determined using assumptions and estimates, including projected rental rates over an appropriate holding period and property capitalization rates, to (ii) the carrying amount of the asset. If the aggregate undiscounted cash flows are less than the asset’s carrying amount, an impairment is recorded to the extent that the estimated fair value is less than the asset’s carrying amount. The estimated fair value is determined using a discounted cash flow model of the expected future cash flows through the useful life of the property. The analysis includes an estimate of the future cash flows that are expected to result from the real estate investment’s use and eventual disposition. These cash flows consider factors such as expected future operating income, trends and prospects, the effects of leasing demand, competition and other factors. Real estate assets that are expected to be disposed of are valued at the lower of carrying amount or fair value less costs to sell on an individual asset basis. In June 2024, the Company recorded a $1,086,000 impairment charge at its former Hamilton, Ohio property in connection with its sale (see Note 5). No such impairment charges were recognized against the Company’s real estate portfolio during the years ended December 31, 2023 and 2022. ​
Properties Held-for-Sale | Properties Held-for-Sale ​ Real estate investments are classified as properties held-for-sale when management determines that the investment meets the applicable criteria. Real estate assets that are classified as held-for-sale are: (i) valued at the lower of carrying amount or the estimated fair value less costs to sell on an individual asset basis; and (ii) not depreciated. ​
Investment in Joint Ventures and Variable Interest Entities | Investment in Joint Ventures and Variable Interest Entities ​ The Financial Accounting Standards Board, or FASB, provides guidance for determining whether an entity is a VIE. VIEs are defined as entities in which equity investors do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support. A VIE is required to be consolidated by its primary beneficiary, which is the party that (i) has the power to control the activities that most significantly impact the VIE’s economic performance and (ii) has the obligation to absorb losses, or the right to receive benefits, of the VIE that could potentially be significant to the VIE. ​ The Company assesses the accounting treatment for each of its investments, including a review of each venture or limited liability company or partnership agreement, to determine the rights of each party and whether those rights are protective or participating. The agreements typically contain certain protective rights, such as the NOTE 2 — SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) ​ requirement of partner approval to sell, finance or refinance the property and to pay capital expenditures and operating expenditures outside of the approved budget or operating plan. In situations where, among other things, the Company and its partners jointly (i) approve the annual budget, (ii) approve certain expenditures, (iii) prepare or review and approve the joint venture’s tax return before filing, or (iv) approve each lease at a property, the Company does not consolidate as the Company considers these to be substantive participation rights that result in shared, joint power over the activities that most significantly impact the performance of the joint venture or property. Additionally, the Company assesses the accounting treatment for any interests pursuant to which the Company may have a variable interest as a lessor. Leases may contain certain protective rights, such as the right of sale and the receipt of certain escrow deposits. ​ The Company accounts for its investments in unconsolidated joint ventures under the equity method of accounting. All investments in unconsolidated joint ventures have sufficient equity at risk to permit the entity to finance its activities without additional subordinated financial support and, as a group, the holders of the equity at risk have power through voting rights to direct the activities of these ventures. As a result, none of these joint ventures are VIEs. In addition, the Company shares power with its co-managing members over these entities, and therefore the entities are not consolidated. These investments are recorded initially at cost, as investments in unconsolidated joint ventures, and subsequently adjusted for their share of equity in earnings, cash contributions and distributions. None of the joint venture debt is recourse to the Company, subject to standard carve-outs. ​ The Company reviews on a quarterly basis its investments in unconsolidated joint ventures for other-than-temporary losses in investment value. Any decline that is not expected to be recovered based on the underlying assets of the investment is considered other than temporary and an impairment charge is recorded as a reduction in the carrying value of the investment. During the three years ended December 31, 2024, there were no impairment charges related to the Company’s investments in unconsolidated joint ventures. ​ The Company has elected to follow the cumulative earnings approach when assessing, for the consolidated statement of cash flows, whether the distribution from the investee is a return of the investor’s investment as compared to a return on its investment. The source of the cash generated by the investee to fund the distribution is not a factor in the analysis (that is, it does not matter whether the cash was generated through investee refinancing, sale of assets or operating results). Consequently, the investor only considers the relationship between the cash received from the investee to its equity in the undistributed earnings of the investee, on a cumulative basis, in assessing whether the distribution from the investee is a return on or a return of its investment. Cash received from the unconsolidated entity is presumed to be a return on the investment to the extent that, on a cumulative basis, distributions received by the investor are less than its share of the equity in the undistributed earnings of the entity. ​
Fair Value Measurements | Fair Value Measurements ​ The Company measures the fair value of financial instruments based on the assumptions that market participants would use in pricing the asset or liability. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). As a basis for considering market participant assumptions in fair value measurements, a fair value hierarchy distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity and the reporting entity’s own assumptions about market participant assumptions. In accordance with the fair value hierarchy, Level 1 assets/liabilities are valued based on quoted prices for identical instruments in active markets, Level 2 assets/liabilities are valued based on quoted prices in active markets for similar instruments, on quoted prices in less active or inactive markets, or on other “observable” market inputs and Level 3 assets/liabilities are valued based on significant “unobservable” market inputs.
Derivatives and Hedging Activities | Derivatives and Hedging Activities ​ The Company uses interest rate swaps to add stability to interest expense; not for trading or speculative purposes. ​ The Company records all derivatives on the consolidated balance sheets at fair value using widely accepted valuation techniques including a discounted cash flow analysis on the expected cash flows of the derivatives. In addition, the Company incorporates credit valuation adjustments to appropriately reflect both its own non-performance risk and the respective counterparty’s non-performance risk in the fair value measurements. These counterparties are generally large financial institutions engaged in providing a variety of financial services. These institutions generally face similar risks regarding adverse changes in market and economic conditions including, but not limited to, fluctuations in interest rates, exchange rates, equity and commodity prices and credit spreads. ​ The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows are considered cash flow hedges. For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivative is initially reported in accumulated other comprehensive income (outside of earnings) and subsequently reclassified to earnings in the period in which the hedged transaction becomes ineffective. For derivatives not designated as cash flow hedges, changes in the fair value of the derivative are recognized directly in earnings in the period in which the change occurs; however, the Company’s policy is to not enter into such transactions. ​
Stock Based Compensation | Stock Based Compensation ​ The fair value of restricted stock grants and restricted stock units (“RSUs”), determined as of the date of grant, is amortized into general and administrative expense over the respective vesting period. The deferred compensation to be recognized as expense is net of forfeitures. The Company recognizes the effect of forfeitures when they occur and previously recognized compensation expense is reversed in the period the grant or unit is forfeited. For share-based awards with a performance or market measure, the Company recognizes compensation expense over the requisite service period and the performance assumptions are re-evaluated quarterly. The requisite service period begins on the date the Compensation Committee of the Company’s Board of Directors authorizes the award, adopts any relevant performance measures and communicates the award to the recipient. ​
Income Taxes | Income Taxes ​ The Company is qualified as a REIT under the applicable provisions of the Internal Revenue Code. Under these provisions, the Company will not be subject to Federal, and generally, state and local income taxes, on amounts distributed to stockholders, provided it distributes at least 90% of its ordinary taxable income and meets certain other conditions. ​ The Company follows a two-step approach for evaluating uncertain tax positions. Recognition (step one) occurs when an enterprise concludes that a tax position, based solely on its technical merits, is more-likely-than-not to be sustained upon examination. Measurement (step two) determines the amount of benefit that more-likely-than-not will be realized upon settlement. Derecognition of a tax position that was previously recognized would occur when a company subsequently determines that a tax position no longer meets the more-likely-than- not threshold of being sustained. The use of a valuation allowance as a substitute for derecognition of tax positions is prohibited. The Company has not identified any uncertain tax positions requiring accrual.
Cash and Cash Equivalents | ​ All highly liquid investments with original maturities of three months or less when purchased are considered to be cash equivalents. ​
Concentration of Credit Risk | Concentration of Credit Risk ​ The Company maintains cash accounts at various financial institutions. While the Company attempts to limit any financial exposure, substantially all of its deposit balances exceed federally insured limits. The Company has not experienced any losses on such accounts. ​ The Company’s properties are located in 31 states. Only properties in one state, South Carolina, contributed more than 10% to the Company’s total revenues (i.e., 11.6% in 2024 and 10.3% in 2023). No real estate investments in any one state contributed more than 10% to the Company’s total revenues in 2022. ​ No tenant contributed over 10% to the Company’s total revenues in any of the past three years. ​
Escrows | Escrows ​ Real estate taxes and other escrows aggregating $3,166,000 and $3,162,000 at December 31, 2024 and 2023, respectively, are included in Escrow, deposits and other assets and receivables. ​
Segment Reporting | Segment Reporting ​ On January 1, 2024, the Company adopted the FASB ASU No. 2023–07, Segment Reporting – Improvements to Reportable Segments Disclosures, as amended, which enhances disclosures of significant segment expenses regularly provided to the chief operating decision maker. ​ Substantially all of the Company’s real estate assets, at acquisition, are comprised of real estate owned that is leased to tenants on a long-term basis. Therefore, the Company aggregates real estate assets for reporting purposes and operates in one reportable segment. ​ The Company’s Chief Operating Decision Makers (“CODMs”) are its Chief Executive Officer and Chief Operating Officer. As the Company operates in one reportable segment, the CODMs are provided the consolidated income statement (detailing total revenues, total operating expenses, operating income and net income). This financial report assists the CODMs in assessing the Company’s financial performance and in allocating resources appropriately. ​
New Accounting Pronouncements | New Accounting Pronouncement ​ In November 2024, the FASB issued ASU No. 2024–03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220–40): Disaggregation of Income Statement Expenses, which requires disaggregated disclosure of income statement expenses into specified categories within the footnotes to the financial statements. ASU No. 2024–03 is applicable for fiscal years beginning after December 15, 2026. The Company is in the process of evaluating the new guidance to determine the extent to which it will impact the Company’s consolidated financial statements.
