SIGNIFICANT ACCOUNTING POLICIES
Principles of Consolidation/Basis of Preparation	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.
Segment Reporting	Segment Reporting 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.
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. During the three years ended December 31, 2022, there were no impairment charges related to the Company’s real estate portfolio.
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.
Depreciation and Amortization	Depreciation and Amortization Depreciation of buildings is computed on the straight-line method over an estimated useful life of 40 years. Depreciation of building improvements is computed on the straight-line method over the estimated useful life of the improvements. If the Company determines it is the owner of tenant improvements, the amounts funded to construct the tenant improvements are treated as a capital asset and depreciated over the lesser of the remaining lease term or the estimated useful life of the improvements on the straight-line method. Leasehold interest and the related ground lease payments are amortized over the initial lease term of the leasehold position. Depreciation expense (including amortization of a leasehold position, lease origination costs, and capitalized leasing commissions) was $23,781,000, $22,832,000 and $22,964,000, for 2022, 2021 and 2020, respectively.
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 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, 2022, there were no impairment charges related to the Company’s investments in unconsolidated joint ventures. NOTE 2—SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) 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.
Deferred Financing Costs	Deferred Financing Costs Mortgage and credit line costs are deferred and amortized on a straight-line basis over the terms of the respective debt obligations, which approximates the effective interest method. At December 31, 2022 and 2021, accumulated amortization of such costs was $4,791,000 and $4,684,000, respectively. The Company presents unamortized deferred financing costs as a direct deduction from the carrying amount of the associated debt liability.
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	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. No real estate investments in any one state contributed more than 10% to the Company’s total revenues in any of the past three years. 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 $559,000 and $502,000 at December 31, 2022 and 2021, respectively, are included in Escrow, deposits and other assets and receivables.

Disclosure of accounting policy for consolidation to describe the significant judgments and assumptions made in determining whether a variable interest held by the entity requires the variable interest entity to be consolidated and (or) disclose information about its involvement with the variable interest entity; the methodology used by the entity for determining whether or not it is the primary beneficiary of the variable interest entity; and the significant factors considered and judgments made in determining that the power to direct the activities that significantly impact the economic performance of the variable interest entity are shared (as defined) and accounting policy for the equity method of accounting for investments in common stock or other interests including unconsolidated subsidiaries, corporate joint ventures, noncontrolling interests in real estate ventures, limited partnerships, and limited liability companies. The accounting policy may include information such as: (1) initially recording an investment in the stock of an investee at cost; (2) adjusting the carrying amount of the investment to recognize the investor's share of the earnings or losses of the investee after the date of acquisition; and (3) adjustments to reflect the investor's share of changes in the investee's capital (dividends).
