SUMMARY ACCOUNTING POLICIES
SUMMARY ACCOUNTING POLICIES	NOTE 2 – SUMMARY ACCOUNTING POLICIES Principles of Consolidation/Basis of Preparation The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and include all of the information and disclosures required by U.S. Generally Accepted Accounting Principles (“GAAP”) for interim reporting. Accordingly, they do not include all of the disclosures required by GAAP for complete financial statement disclosures. In the opinion of management, all adjustments of a normal recurring nature necessary for fair presentation have been included. The results of operations for the three months ended March 31, 2021 and 2020 are not necessarily indicative of the results for the full year. These statements should be read in conjunction with the consolidated financial statements and related notes included in OLP’s Annual Report on Form 10-K for the year ended December 31, 2020. The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. 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. ​ 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. ​ NOTE 2 – SUMMARY ACCOUNTING POLICIES (CONTINUED) 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 months ended March 31, 2021 and 2020, 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. ​

LEASES
LEASES	NOTE 3 – LEASES Lessor Accounting The Company owns rental properties which are leased to tenants under operating leases with current expirations ranging from 2021 to 2055, with options to extend terminate components Fixed lease revenues represent the base rent that each tenant is required to pay in accordance with the terms of their respective leases reported on a straight-line basis over the non-cancelable term of the lease. Variable lease revenues include payments based on (i) tenant reimbursements, (ii) changes in the index or market-based indices after the inception of the lease, (iii) percentage rents or (iv) the operating performance of the property. Variable lease revenues are not recognized until the specific events that trigger the variable payments have occurred. NOTE 3 – LEASES (CONTINUED) The components of lease revenues are as follows (amounts in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ ​ March 31, ​ 2021 2020 Fixed lease revenues ​ $ 17,465 ​ $ 18,067 Variable lease revenues ​ ​ 2,987 ​ ​ 2,982 Lease revenues (a) ​ $ 20,452 ​ $ 21,049 (a) Excludes $232 and $190 of amortization related to lease intangible assets and liabilities for the three months ended March 31, 2021 and 2020, respectively. In many of the Company’s leases, the tenant is obligated to pay the real estate taxes, insurance, and certain other expenses directly to the vendor. These obligations, which have been assumed by the tenants, are not reflected in our consolidated financial statements. To the extent any such tenant defaults on its lease or if it is deemed probable that the tenant will fail to pay for such obligations, a liability for such obligations would be recorded. During the year ended December 31, 2020, in response to requests for rent relief from tenants impacted by the COVID-19 pandemic and the governmental and non-governmental responses thereto, the Company deferred and accrued $3,360,000 of rent payments. For 2020, the three months ended March 31, 2021 and for April 2021, the Company collected $497,000, $843,000 and $359,000, respectively, of such deferred rents. The $1,661,000 balance of deferred rents is deemed collectible and is expected to be collected from 2021 through 2023. On a quarterly basis, the Company assesses the collectability of substantially all lease payments due by reviewing the tenant’s payment history or financial condition. Changes to collectability are recognized as a current period adjustment to rental revenue. In February 2021, the Company executed lease amendments with Regal Cinemas, a tenant at two properties, which was adversely affected by the pandemic. In connection with the lease amendments, the Company agreed to defer an aggregate of $1,449,000 of rent otherwise payable from September 2020 through August 2021, the tenant agreed to pay an aggregate of $441,000 of rent during that same period and the parties extended the lease for one of these properties for two years . Through April 30, 2021, the tenant is current on all lease obligations in accordance with these lease amendments. The Company did not accrue the deferred rents due from September 2020 through March 2021 as collections were deemed less than probable. The Company has assessed the collectability of all recorded lease payments as probable as of March 31, 2021. Minimum Future Rents As of March 31, 2021, the minimum future contractual rents to be received on non-cancellable operating leases are included in the table below (amounts in thousands). The minimum future contractual rents do not include (i) straight-line rent or amortization of intangibles, (ii) COVID-19 lease deferral repayments accrued to rental income in 2020 and (iii) variable lease payments as described above. ​ ​ ​ ​ ​ From April 1 – December 31, 2021 ​ $ 52,571 For the year ended December 31, ​ ​ ​ 2022 ​ ​ 62,646 2023 ​ ​ 53,279 2024 ​ ​ 44,609 2025 ​ ​ 40,391 2026 ​ ​ 34,860 Thereafter ​ ​ 129,439 Total ​ $ 417,795 ​ NOTE 3 – LEASES (CONTINUED) Lease Termination Fees In January 2021, the Company received $350,000 as a lease termination fee from a retail tenant in connection with the exercise of an early lease termination option. The Company is amortizing this to revenues over the revised lease term expiring January 15, 2022. In December 2020, the Company received $88,000 as a lease termination fee from an industrial tenant in connection with the exercise of an early lease termination option. The Company is amortizing this to revenues over the revised lease term expiring May 31, 2021. Lessee Accounting Ground Lease The Company is a lessee under a ground lease in Greensboro, North Carolina, which is classified as an operating lease. The ground lease expires March 3, 2025 and provides for up to four, 5-year renewal options and one seven-month renewal option. As of March 31, 2021, the remaining lease term, including renewal options deemed exercised, is 13.9 years. The Company recognized lease expense related to this ground lease of $150,000 and $131,000 for the three months ended March 31, 2021 and 2020, respectively, which is included in Real estate expenses on the consolidated statements of income. Office Lease The Company is a lessee under a corporate office lease in Great Neck, New York, which is classified as an operating lease. The lease expires on December 31, 2031 and provides a 5-year renewal option. As of March 31, 2021, the remaining lease term, including the renewal option deemed exercised, is 15.8 years. The Company recognized lease expense related to this office lease of $14,000 for both the three months ended March 31, 2021 and 2020, which is included in General and administrative expenses on the consolidated statements of income. Minimum Future Lease Payments As of March 31, 2021, the minimum future lease payments related to the operating ground and office leases are as follows (amounts in thousands): ​ ​ ​ ​ ​ From April 1 – December 31, 2021 ​ $ 383 For the year ended December 31, ​ ​ ​ 2022 ​ ​ 506 2023 ​ 507 2024 ​ 557 2025 ​ 626 2026 ​ 627 Thereafter ​ 6,220 Total undiscounted cash flows ​ $ 9,426 Present value discount ​ (2,000) Lease liability ​ $ 7,426 ​

VARIABLE INTEREST ENTITIES, CONTINGENT LIABILITY AND CONSOLIDATED JOINT VENTURES
VARIABLE INTEREST ENTITIES, CONTINGENT LIABILITY AND CONSOLIDATED JOINT VENTURES	NOTE 4 – VARIABLE INTEREST ENTITIES, CONTINGENT LIABILITY AND CONSOLIDATED JOINT VENTURES Variable Interest Entity – Ground Lease The Company determined it has a variable interest through its ground lease at its Beachwood, Ohio property (The Vue Apartments) and the owner/operator is a VIE because its equity investment at risk is insufficient to finance its activities without additional subordinated financial support. The Company further determined that it is not the primary beneficiary of this VIE because the Company does not have power over the activities that most significantly impact the owner/operator’s economic performance and therefore, does not consolidate this VIE for financial statement purposes. Accordingly, the Company accounts for this investment as land and the revenues from the ground lease as Rental income, net. Ground lease rental income amounted to $243,000 for the three months ended March 31, 2020. No ground lease rental income was collected during the three months ended March 31, 2021. As of March 31, 2021, the VIE’s maximum exposure to loss was $14,560,000 which represented the carrying amount of the land. In purchasing the property in 2016, the owner/operator obtained a mortgage for $67,444,000 from a third party which, together with the Company’s purchase of the land, provided substantially all of the funds to acquire the multi-family property. The Company provided its land as collateral for the owner/operator’s mortgage loan; accordingly, the land position is subordinated to the mortgage. The mortgage balance was $66,870,000 as of March 31, 2021. Pursuant to the ground lease, as amended, the Company agreed, in its discretion, to fund 78% of (i) any operating expense shortfalls at the property and (ii) any capital expenditures required at the property. The Company funded $430,000 during the three months ended March 31, 2021 and an additional $611,000 from April 1 through May 3, 2021. These amounts are included as part of the carrying amount of the land. Variable Interest Entities – Consolidated Joint Ventures The Company has determined that the four consolidated joint ventures in which it holds between a 90% to 95 % interest are VIEs because the non-controlling interests do not hold substantive kick-out or participating rights. The Company has determined it is the primary beneficiary of these VIEs as it has the power to direct the activities that most significantly impact each joint venture’s performance including management, approval of expenditures, and the obligation to absorb the losses or rights to receive benefits. Accordingly, the Company consolidates the operations of these VIEs for financial statement purposes. The VIEs’ creditors do not have recourse to the assets of the Company other than those held by the applicable joint venture. The following is a summary of the consolidated VIEs’ carrying amounts and classification in the Company’s consolidated balance sheets, none of which are restricted (amounts in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, ​ December 31, ​ 2021 2020 Land ​ $ 12,158 ​ $ 12,158 Buildings and improvements, net of accumulated depreciation of $5,454 and $5,232, respectively ​ ​ 23,284 ​ ​ 23,372 Cash ​ ​ 1,195 ​ ​ 1,102 Unbilled rent receivable ​ ​ 856 ​ ​ 861 Unamortized intangible lease assets, net ​ ​ 605 ​ ​ 627 Escrow, deposits and other assets and receivables ​ ​ 1,051 ​ ​ 1,089 Mortgages payable, net of unamortized deferred financing costs of $238 and $253, respectively ​ ​ 23,313 ​ ​ 23,530 Accrued expenses and other liabilities ​ ​ 885 ​ ​ 752 Unamortized intangible lease liabilities, net ​ ​ 513 ​ ​ 526 Accumulated other comprehensive loss ​ ​ (99) ​ ​ (127) Non-controlling interests in consolidated joint ventures ​ ​ 1,198 ​ ​ 1,193 ​ As of March 31, 2021 and December 31, 2020, MCB Real Estate, LLC and its affiliates (‘‘MCB’’) are the Company’s joint venture partner in three consolidated joint ventures in which the Company has aggregate equity investments of approximately $7,489,000 and $7,495,000, respectively.

EARNINGS PER COMMON SHARE
EARNINGS PER COMMON SHARE	NOTE 8 – EARNINGS PER COMMON SHARE ​ Basic earnings per share was determined by dividing net income allocable to common stockholders for each period by the weighted average number of shares of common stock outstanding during the applicable period. Net income is also allocated to the unvested restricted stock outstanding during each period, as the restricted stock is entitled to receive dividends and is therefore considered a participating security. As of March 31, 2021, the shares of common stock underlying the RSUs awarded between 2018 and 2020 under the 2019 and 2016 Incentive Plans (See Note 9) are excluded from the basic earnings per share calculation, as these units are not participating securities. Diluted earnings per share reflects the potential dilution that could occur if securities or other rights exercisable for, or convertible into, common stock were exercised or converted or otherwise resulted in the issuance of common stock that shared in the earnings of the Company. The following table provides a reconciliation of the numerator and denominator of earnings per share calculations (amounts in thousands, except per share amounts): ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ ​ March 31, ​ 2021 2020 Numerator for basic and diluted earnings per share: ​ Net income ​ $ 2,957 ​ $ 7,831 Add (deduct) net loss (income) attributable to non-controlling interests ​ 5 ​ (5) Deduct earnings allocated to unvested restricted stock (a) ​ (325) ​ (316) Net income available for common stockholders: basic and diluted ​ $ 2,637 ​ $ 7,510 Denominator for basic earnings per share: ​ ​ ​ ​ ​ ​ Weighted average number of common shares outstanding ​ 20,003 ​ 19,361 Effect of dilutive securities: ​ ​ ​ ​ ​ RSUs ​ 58 ​ 13 Denominator for diluted earnings per share: ​ ​ ​ ​ ​ ​ Weighted average number of shares ​ 20,061 ​ 19,374 ​ ​ ​ ​ ​ ​ ​ Earnings per common share, basic and diluted ​ $ .13 ​ $ .39 (a) Represents an allocation of distributed earnings to unvested restricted stock that, as participating securities, are entitled to receive dividends.

The quarterly dividend is payable on April 7, 2021 to stockholders of record on March 24, 2021. Dividend Reinvestment Plan On June 10, 2020, the Company temporarily suspended the dividend reinvestment feature of its Dividend Reinvestment Plan (the “DRP”). The DRP, among other things, provided stockholders with the opportunity to reinvest all, or a portion of, their cash dividends paid on the Company’s common stock in additional shares of its common stock, at a discount of up to 5% from the market price (as such price is calculated pursuant to the DRP). The discount was determined in the Company’s sole discretion and had been offered at a 5% discount from market. Under the DRP, the Company issued 7,000 shares of common stock during the three months ended March 31, 2020. NOTE 9 – STOCKHOLDERS’ EQUITY (CONTINUED) Stock Based Compensation The Company’s 2019 Incentive Plan (“Plan”), approved by the Company’s stockholders in June 2019, permits the Company to grant, among other things, stock options, restricted stock, RSUs, performance share awards and dividend equivalent rights and any one or more of the foregoing to its employees, officers, directors and consultants. A maximum of 750,000 shares of the Company’s common stock is authorized for issuance pursuant to this Plan. As of March 31, 2021, an aggregate of 450,952 shares subject to awards in the form of restricted stock (300,900 shares) and RSUs (150,052 shares) are outstanding under the Plan. Under the Company’s 2016 equity incentive plan (the “Prior Plan”), as of March 31, 2021, (i) an aggregate of 495,900 shares in the form of restricted stock (422,150 shares) and RSUs (73,750 shares) are outstanding and have not yet vested, and (ii) with respect to 76,250 shares of common stock underlying RSUs that had been granted in 2017, 24,343 shares were deemed to have vested in 2020 and such shares were issued after the Compensation Committee determined that the metrics with respect to such shares had been satisfied. RSUs with respect to the 51,907 share balance were forfeited. No additional awards may be granted under the Prior Plan. For accounting purposes, the restricted stock is not included in the shares shown as outstanding on the balance sheet until they vest; however, dividends are paid on the unvested shares. The restricted stock grants are charged to General and administrative expense over the respective vesting periods based on the market value of the common stock on the grant date. Unless earlier forfeited because the participant’s relationship with the Company terminated, unvested restricted stock awards vest five years In 2020, 2019 and 2018, the Company granted RSUs exchangeable for up to 75,026, 77,776, and 76,250 shares, respectively, of common stock upon satisfaction, through June 30, 2023, June 30, 2022 and June 30, 2021, respectively, of specified conditions. Specifically, up to 50% of these RSUs vest upon achievement of metrics related to average annual total stockholder return (the “TSR Awards”), which metrics meet the definition of a market condition, and up to 50% vest upon achievement of metrics related to average annual return on capital (the “ROC Awards”), which metrics meet the definition of a performance condition. The holders of the RSUs are not entitled to dividends or to vote the underlying shares until such RSUs vest and shares are issued. Accordingly, the shares underlying these RSUs are not included in the shares shown as outstanding on the balance sheet. For the TSR Awards, a third party appraiser prepared a Monte Carlo simulation pricing model to determine the fair value, which is recognized ratably over the service period. For the ROC Awards, the fair value is based on the market value on the date of grant and the performance assumptions are re-evaluated quarterly. The Company does not recognize expense on ROC Awards which it does not expect to vest. During 2019, RSUs exchangeable in 2021 and 2022 for an aggregate of 5,250 shares were forfeited. ​ As of March 31, 2021, based on performance and market assumptions, the fair value of the RSUs granted in 2020, 2019 and 2018 is $962,000, $1,446,000 and $1,006,000, respectively. Recognition of such deferred compensation will be charged to General and administrative expense over the respective three year performance cycle.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	3 Months Ended

FAIR VALUE MEASUREMENTS
FAIR VALUE MEASUREMENTS	NOTE 10 – 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. 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 significantly on “unobservable” market inputs. The carrying amounts of cash and cash equivalents, escrow, deposits and other assets and receivables (excluding interest rate swaps), dividends payable, and accrued expenses and other liabilities (excluding interest rate swaps), are not measured at fair value on a recurring basis, but are considered to be recorded at amounts that approximate fair value. At March 31, 2021, the $444,282,000 estimated fair value of the Company’s mortgages payable is greater than their $427,955,000 carrying value (before unamortized deferred financing costs) by approximately $16,327,000 assuming a blended market interest rate of 3.5% based on 6.9 year weighted average remaining term to maturity of the mortgages. At December 31, 2020, the $461,965,000 estimated fair value of the Company’s mortgages payable is greater than their $433,549,000 carrying value (before unamortized deferred financing costs) by approximately $28,416,000, assuming a blended market interest rate of 3.0% based on the 7.1 year weighted average remaining term to maturity of the mortgages. At March 31, 2021 and December 31, 2020, the carrying amount of the Company’s line of credit (before unamortized deferred financing costs) of $15,450,000 and $12,950,000, respectively, approximates its fair value. The fair value of the Company’s mortgages payable and line of credit are estimated using unobservable inputs such as available market information and discounted cash flow analysis based on borrowing rates the Company believes it could obtain with similar terms and maturities. These fair value measurements fall within Level 3 of the fair value hierarchy. Considerable judgment is necessary to interpret market data and develop estimated fair value. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. Fair Value on a Recurring Basis As of March 31, 2021, the Company had in effect 22 interest rate derivatives, all of which were interest rate swaps, related to 22 outstanding mortgage loans with an aggregate $81,862,000 notional amount maturing between 2021 and 2028 (weighted average remaining term to maturity of 3.7 years). The Company’s objective in using interest rate swaps is to add stability to interest expense. These interest rate swaps, all of which were designated as cash flow hedges, converted LIBOR based variable rate mortgages to fixed annual rate mortgages (with interest rates ranging from 3.02% to 5.16% and a weighted average interest rate of 3.95 % at March 31, 2021). The Company does not use derivatives for trading or speculative purposes. The fair value of the Company’s derivative financial instruments, all of which were financial liabilities, was determined to be the following (amounts in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Carrying and ​ Balance Sheet Financial liabilities: As of Fair Value Classification Interest rate swaps ​ March 31, 2021 ​ $ 3,511 ​ Other liabilities ​ ​ December 31, 2020 ​ ​ 5,012 ​ ​ ​ NOTE 10 – FAIR VALUE MEASUREMENTS (CONTINUED) Fair values are approximated using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of the derivatives. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. Although the Company has determined the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with it use Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default by the Company and its counterparty. As of March 31, 2021, the Company has assessed and determined the impact of the credit valuation adjustments on the overall valuation of its derivative positions is not significant. As a result, the Company determined its derivative valuation is classified in Level 2 of the fair value hierarchy. The Company does not currently own any financial instruments that are measured on a recurring basis and that are classified as Level 1 or 3. The following table presents the effect of the Company’s derivative financial instruments on the consolidated statements of income for the periods presented (amounts in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ ​ March 31, ​ 2021 2020 Amount of gain (loss) recognized on derivatives in other comprehensive loss ​ $ 1,093 ​ $ (4,928) Amount of reclassification from Accumulated other comprehensive loss into Interest expense ​ ​ (408) ​ ​ (110) ​ No amounts were reclassified from Accumulated other comprehensive loss into interest expense as a result of forecasted transactions being no longer probable of occurring for the three months ended March 31, 2021 and 2020. No gain or loss was recognized with respect to amounts excluded from effectiveness testing on the Company’s cash flow hedges for the three months ended March 31, 2021 and 2020. During the twelve months ending March 31, 2022, the Company estimates an additional $1,547,000 will be reclassified from Accumulated other comprehensive loss as an increase to Interest expense. The derivative agreements in effect at March 31, 2021 provide that if the wholly-owned subsidiary of the Company which is a party to such agreement defaults or is capable of being declared in default on any of its indebtedness, then a default can be declared on such subsidiary’s derivative obligation. In addition, the Company is a party to the derivative agreements and if there is a default by the subsidiary on the loan subject to the derivative agreement to which the Company is a party and if there are swap breakage losses on account of the derivative being terminated early, the Company could be held liable for such swap breakage losses. As of March 31, 2021 and December 31, 2020, the fair value of the derivatives in a liability position, including accrued interest of $123,000 and $120,000, respectively, but excluding any adjustments for non-performance risk, was approximately $3,727,000 and $5,314,000 , respectively. In the event the Company had breached the contractual provisions of the derivative contracts, it would be required to settle its obligations thereunder at their termination liability value of as of March 31, 2021 and December 31, 2020, respectively. This termination liability value, net of adjustments for non-performance risk of

Insurance Recoveries on Hurricane Casualty In 2020, a portion of a multi-tenanted building at the Company’s Lake Charles, Louisiana property was damaged due to Hurricane Laura and the Company recognized an impairment loss of $430,000 for the damaged portion of the building. The Company submitted a claim to its insurance carrier to cover, subject to a $250,000 deductible, the (i) estimated $2,100,000 cost to rebuild the damaged portion of the building and (ii) $129,000 of losses in rental income. In 2020, the Company recorded a receivable of $430,000 related to this claim as income on insurance recoveries, of which $150,000 was collected by December 31, 2020.

NEW ACCOUNTING PRONOUNCEMENTS
NEW ACCOUNTING PRONOUNCEMENTS	NOTE 13 – NEW ACCOUNTING PRONOUNCEMENTS In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848) , which contains practical expedients for reference rate reform related activities 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. Through the three months ended March 31, 2021, the Company has 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. The Company may apply other elections, as applicable, as additional changes in the market occur. The Company continues to evaluate the new guidance to determine the extent to which it may impact the Company’s consolidated financial statements.

SUMMARY ACCOUNTING POLICIES
Principles of Consolidation/Basis of Preparation	Principles of Consolidation/Basis of Preparation The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and include all of the information and disclosures required by U.S. Generally Accepted Accounting Principles (“GAAP”) for interim reporting. Accordingly, they do not include all of the disclosures required by GAAP for complete financial statement disclosures. In the opinion of management, all adjustments of a normal recurring nature necessary for fair presentation have been included. The results of operations for the three months ended March 31, 2021 and 2020 are not necessarily indicative of the results for the full year. These statements should be read in conjunction with the consolidated financial statements and related notes included in OLP’s Annual Report on Form 10-K for the year ended December 31, 2020. The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. 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. ​
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. ​ NOTE 2 – SUMMARY ACCOUNTING POLICIES (CONTINUED) 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 months ended March 31, 2021 and 2020, 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.
