Investments in Affiliates: Affiliates included in the financial statements accounted for under the equity method: 35.7% 5% 5% (See Note 17 and Note 19 ) Navios Partners evaluates its investment in Navios Containers for other than temporary impairment (“OTTI”) on a quarterly basis. Consideration is given to: (i) the length of time and the extent to which the fair value has been less than the carrying value; (ii) the financial condition and near-term prospects of Navios Containers; and (iii) the intent and ability of the Company to retain its investment in Navios Containers, for a period of time sufficient to allow for any anticipated recovery in fair value (see Note 19 — Investment in affiliates (c) Use of Estimates (d) Cash and Cash Equivalents (e) Restricted Cash 6,152 7,048 5,273 (f) Accounts Receivable, Net : 2,990 1,495 (g) Inventories : (h) Vessels, Net Expenditures for routine maintenance and repairs are expensed as incurred. Depreciation is computed using the straight line 340 Management estimates the useful life of the Company’s vessels to be 25 30 (i) Assets Held for Sale (j) Impairment of Long Lived Assets Undiscounted projected net operating cash flows are determined for each asset group and compared to the carrying value of the vessel, the unamortized portion of deferred drydock and special survey costs related to the vessel and the related carrying value of the intangible assets with respect to the time charter agreement attached to that vessel or the carrying value of deposits for newbuildings. Within the shipping industry, vessels are customarily bought and sold with a charter attached. The value of the charter may be favorable or unfavorable when comparing the charter rate to then current market rates. The loss recognized either on impairment (or on disposition) will reflect the excess of carrying value over fair value (selling price) for the vessel asset group. During the fourth quarter of fiscal year 2020, the Company concluded that events occurred and circumstances had changed, which indicated that potential impairment of Navios Partners' long-lived assets may exist. These indicators included volatility in the charter market as well as the potential impact the current marketplace may have on the Company’s future operations. As a result, an impairment assessment of long-lived assets (step one) was performed. The Company determined the undiscounted projected net operating cash flows for each vessel and compared it to the vessels' carrying value together with the carrying value of deferred drydock and special survey costs related to the vessel and the carrying value of the related intangible assets, if applicable. The significant factors and assumptions the Company used in the undiscounted projected net operating cash flow analysis included: determining the projected net operating cash flows by considering the charter revenues from existing time charters for the fixed fleet days (Navios Partners' remaining charter agreement rates) and an estimated daily time charter equivalent for the unfixed days (based on a combination of one-year average historical time charter rates for the first year and ten-year average historical one-year time charter rates for the remaining period), over the remaining economic life of each vessel, net of brokerage and address commissions, and excluding days of scheduled off-hires, management fees as determined by the Management Agreement in effect until December 2024 and thereafter assuming an increase of 3.0% 98.6% Where the undiscounted projected net operating cash flows do not exceed the carrying value of an asset group, management proceeded to perform step two of the impairment assessment. In step two of the impairment assessment, the Company determined fair value of its vessels through a combination of a discounted cash flow analysis utilizing market participant assumptions from available market data and third-party valuations from independent ship brokers performed on an individual vessel basis. The significant factors and assumptions used by management in determining fair value of vessels included those in developing the projected net operating cash flows over the remaining economic life of each vessel and the discount rate. As of December 31, 2020, the Company’s assessment concluded that step two of the impairment analysis was required for certain of its vessels held and used, as the undiscounted projected net operating cash flows did not exceed the carrying value. As a result, the Company recorded an impairment loss of $ 50,991 As of December 31, 2019, the Company’s assessment concluded that step two of the impairment analysis was required for certain of its vessels held and used, as the undiscounted projected net operating cash flows did not exceed the carrying value. As a result, the Company recorded an impairment loss of $ 29,335 As of December 31, 2018, the Company’s assessment concluded that step two of the impairment analysis was not required for its vessels held and used, as the undiscounted projected net operating cash flows exceeded the carrying value. As of June 30, 2020, the Company concluded that events and circumstances triggered the existence of potential impairment of its containerships. These indicators included volatility in the charter market and market values for containerships. As a result, the Company performed step one of the impairment assessment of its containerships by comparing the undiscounted projected net operating cash flows for each vessel to its carrying value. As of June 30, 2020, the Company’s assessment concluded that step two of the impairment analysis was required for three containerships held and used, as the undiscounted projected net operating cash flows did not exceed the carrying value. As a result, the Company recorded an impairment loss of $ 6,800 During the years ended December 31, 2020, 2019 and 2018, an impairment loss of $ 13,786 7,345 44,344 The total impairment loss recognized amounted to $ 71,577 36,680 44,344 (k) Deferred Drydock and Special Survey Costs 30 60 Costs capitalized as part of the drydocking or special survey consist principally of the actual costs incurred at the yard, and expenses relating to spare parts, paints, lubricants and services incurred solely during the drydocking or special survey period. For the years ended December 31, 2020, 2019 and 2018, the amortization expense was $ 10,337 6,916 6,180 (l) Deferred Finance Costs 2,141 10,916 7,258 (m) Intangible Assets and Liabilities The amortizable value of favorable and unfavorable leases is amortized over the remaining life of the lease term and the amortization expense is included under the caption “Depreciation and amortization” in the Consolidated Statements of Operations. The amortizable value of favorable leases would be considered impaired if its carrying value could not be recovered from the future undiscounted cash flows associated with the asset. Management, after considering various indicators, performed an impairment test which included intangible assets as described in paragraph (j) above. As of December 31, 2020, 2019 and 2018 there was no impairment of intangible assets. (n) Foreign Currency Translation : (o) Provisions Navios Partners, through the management agreement, participates in Protection and Indemnity (P&I) insurance coverage plans provided by mutual insurance societies known as P&I clubs. Under the terms of these plans, participants may be required to pay additional premiums (supplementary calls) to fund operating deficits incurred by the clubs (“back calls”). Obligations for back calls are accrued annually based on information provided by the P&I clubs. (p) Segment Reporting Segment information). (q) Revenue and Expense Recognition : The Company's contract revenues from time chartering and pooling arrangements are governed by ASU 2016-02 (ASC 842) “Leases”. Upon adoption of ASC 606 and ASC 842, the timing and recognition of earnings from the pool arrangements and time charter contracts to which the Company is party did not change from previous practice. The Company has determined to recognize lease revenue as a combined single lease component for all time charters (operating leases) as the related lease component and non-lease components will have the same timing and pattern of the revenue recognition of the combined single lease component. The performance obligations in a time charter contract are satisfied over term of the contract beginning when the vessel is delivered to the charterer until it is redelivered back to the Company. As a result of the adoption of these standards, there was no effect on the Company's retained earnings, as at January 1, 2018. Revenue from time chartering Revenues from time chartering of vessels are accounted for as operating leases and are thus recognized on a straight line basis as the average lease revenue over the rental periods of such charter agreements, as service is performed. A time charter involves placing a vessel at the charterers' disposal for a period of time during which the charterer uses the vessel in return for the payment of a specified daily hire rate. Short period charters for less than three months are referred to as spot-charters. Charters extending three months to a year are generally referred to as medium-term charters. All other charters are considered long-term. Under time charters, operating costs such as for crews, maintenance and insurance are typically paid by the owner of the vessel. Revenue from time chartering of vessels amounted to $ 218,809 204,920 215,877 Revenue from voyage contracts The Company's revenues earned under voyage contracts (revenues for the transportation of cargo) were previously recognized ratably over the estimated relative transit time of each voyage. A voyage was deemed to commence when a vessel was available for loading and was deemed to end upon the completion of the discharge of the current cargo. Estimated losses on voyages are provided for in full at the time such losses become evident. Under a voyage charter, a vessel is provided for the transportation of specific goods between specific ports in return for payment of an agreed upon freight per ton of cargo. Upon adoption of ASC 606, the Company recognizes revenue ratably from port of loading to when the charterer's cargo is discharged as well as defer costs that meet the definition of “costs to fulfill a contract” and relate directly to the contract. During 2017, no freight voyage existed and therefore, there was no impact on the Company's retained earnings as at January 1, 2018. Revenue from voyage contracts amounted to $ 3,754 9,416 9,660 Pooling arrangements For vessels operating in pooling arrangements, the Company earns a portion of total revenues generated by the pool, net of expenses incurred by the pool. The amount allocated to each pool participant vessel, including the Company's vessels, is determined in accordance with an agreed-upon formula, which is determined by points awarded to each vessel in the pool based on the vessel's age, design and other performance characteristics. Revenue under pooling arrangements is accounted for as variable rate operating leases on the accrual basis and is recognized when an agreement with the pool exists, price is fixed, service is provided and the collectability is reasonably assured. The allocation of such net revenue may be subject to future adjustments by the pool however, such changes are not expected to be material. The Company recognizes net pool revenue on a monthly and quarterly basis, when the vessel has participated in a pool during the period and the amount of pool revenue can be estimated reliably based on the pool report. Revenue from vessels operating in pooling arrangements amounted to $ 4,208 5,043 5,817 Revenue from profit-sharing Profit-sharing revenues are calculated at an agreed percentage of the excess of the charterer's average daily income (calculated on a quarterly or half-yearly basis) over an agreed amount and accounted for on an accrual basis based on provisional amounts and for those contracts that provisional accruals cannot be made due to the nature of the profit sharing elements, these are accounted for on the actual cash settlement or when such revenue becomes determinable. Profit sharing revenue for the years ended December 31, 2020, 2019 and 2018 amounted to 0 0 7 Revenues are recorded net of address commissions. Address commissions represent a discount provided directly to the charterers based on a fixed percentage of the agreed upon charter or freight rate. Since address commissions represent a discount (sales incentive) on services rendered by the Company and no identifiable benefit is received in exchange for the consideration provided to the charterer, these commissions are presented as a reduction of revenue. Deferred Revenue and Cash Received in Advance: Time Charter and Voyage Expenses: Direct Vessel Expenses: Prepaid Voyage Costs: Vessel operating expenses (management fees): 4.23 4.33 5.25 6.70 7.40 8.75 In August 2019, Navios Partners extended the duration of its Management Agreement with the Manager until January 1, 2025. In addition, management fees are fixed for two years commencing from January 1, 2020 at: (a) $ 4.35 4.45 5.41 6.90 0.05 3% Following the liquidation of Navios Europe I, Navios Partners acquired three Sub-Panamax and two Panamax Containerships. As per the Management Agreement, as amended in December 2019, management fees are fixed for two years commencing from January 1, 2020 at $ 6.1 0.05 3% Drydocking expenses are reimbursed at cost for all vessels. For the years ended December 31, 2020 and 2019 certain extraordinary fees and costs related to regulatory requirements, including ballast water treatment system installation and exhaust gas cleaning system installation under Company's management agreement, amounted to $ 3,366 16,313 Total vessel operating expenses for each of the years ended December 31, 2020, 2019 and 2018 amounted to $ 93,732 68,188 68,871 General and Administrative Expenses: Total general and administrative expenses charged by the Manager for each of the years ended December 31, 2020, 2019 and 2018 amounted to $ 13,708 10,406 9,344 (r) Financial Instruments Financial Risk Management: Credit risk: Financial instruments that potentially subject Navios Partners to concentrations of credit risk are accounts receivable and cash and cash equivalents. Navios Partners does not believe its exposure to credit risk is likely to have a material adverse effect on its financial position, results of operations or cash flows. For the year ended December 31, 2020 HMM, Singapore Marine and Cargill represented approximately 23.4% 19.5% 11.4% 25.9% 12.3% 10.9% 24.5% Liquidity Risk: Foreign Exchange Risk: (s) Cash Distribution As per the Partnership Agreement, within 45 days following the end of each quarter, to the extent and as may be declared by the Board, an amount equal to 100% of Available Cash with respect to such quarter shall be distributed to the partners as of the record date selected by the Board of Directors. Available Cash: • less the amount of cash reserves established by the Board of Directors to: • provide for the proper conduct of the business (including reserve for maintenance and replacement capital expenditures); • comply with applicable law, any of Navios Partners' debt instruments, or other agreements; or • provide funds for distributions to the unitholders and to the general partner for any one or more of the next four quarters; • plus all cash on hand on the date of determination of Available Cash for the quarter resulting from working capital borrowings made after the end of the quarter. Working capital borrowings are generally borrowings that are made under any revolving credit or similar agreement used solely for working capital purposes or to pay distributions to partners. Available Cash is a quantitative measure used in the publicly traded partnership investment community to assist in evaluating a partnership's ability to make quarterly cash distributions. Available Cash is not required by U.S. GAAP and should not be considered a substitute for net income, cash flow from operating activities and other operations or cash flow statement data prepared in accordance with accounting principles generally accepted in the United States or as a measure of profitability or liquidity. Cash distributions are recorded in the Company's financial statements in the period in which they are declared. Navios Partners paid $ 7,872 13,550 10,261 Maintenance and Replacement Capital Expenditures 36,455 29,039 26,787 (t) Stock-based compensation 946 2,018 2,450 285,763 (u) Income Taxes (v) ( Loss)/Earnings Per Unit (w) Guarantees On November 15, 2012 (as amended and supplemented in March 2014, December 2017 and July 2019), Navios Holdings and Navios Partners entered into an agreement (the “Navios Holdings Guarantee”) by which Navios Holdings would provide supplemental credit default insurance with a maximum cash payment of $ 20,000 5,000 5,000 10,000 (x) Leases For charters classified as finance leases the minimum lease payments are recorded as the gross investment in the lease. The difference between the gross investment in the lease and the sum of the present values of the two components of the gross investment is recorded as unearned income which is amortized to income over the lease term as finance lease interest income to produce a constant periodic rate of return on the net investment in the lease. For charters classified as operating leases where Navios Partners is regarded as the lessor,(see Note 2(q) — Summary of Significant Accounting Policies). In cases of lease agreements where the Company acts as the lessee, the Company recognizes a right-of-use asset and a corresponding lease liability on the consolidated balance sheet. For finance leases, interest expense is determined using the effective interest method and amortization on the right-of-use asset is recognized on a straight line basis over the lease term. For charters classified as operating leases, lease expense is recognized on a straight line basis over the rental periods of such charter agreements, by adding interest expense to the amortization of the right-of-use asset. The expense is included in the caption “Time charter and voyage expenses” in the consolidated statement of Operations. In cases of sale and leaseback transactions, if the transfer of the asset to the lessor does not qualify as a sale, then the transaction constitutes a failed sale and leaseback and is accounted for as a financing transaction. For a sale to have occurred, the control of the asset would need to be transferred to the buyer, and the buyer would need to obtain substantially all the benefits from the use of the asset. Operating lease assets used by Navios Partners are reviewed periodically for potential impairment whenever events or changes in circumstances indicate that the carrying amount may not be fully recoverable. Measurement of the impairment loss is based on the fair value of the asset. Navios Partners determines the fair value of its assets based on management estimates and assumptions by making use of available market data. In evaluating carrying values of operating lease assets, certain indicators of potential impairment are reviewed, such as undiscounted projected operating cash flows, business plans and overall market conditions. Undiscounted projected net operating cash flows are determined for each asset group and compared to the carrying value of the operating lease asset and the carrying value of deposits for the option to acquire a vessel including expenses and interest. If step two of the impairment analysis is required, the analysis includes the use of the discounted cash flow which comprises various assumptions, including the Company’s WACC. During the fourth quarter of fiscal year 2020, management concluded that events occurred and circumstances had changed, which indicated that potential impairment of Navios Partners’ operating lease assets might exist. These indicators included volatility in the charter market as well as the potential impact the current marketplace may have on the Company’s future operations As a result, an impairment assessment of operating lease assets (step one) was performed. The Company determined undiscounted projected net operating cash flows for each chartered-in vessel and compared it to operating lease asset’s carrying value together with the carrying value of deposits for the option to acquire a vessel including expenses and interest. The significant factors and assumptions used in the undiscounted projected net operating cash flow analysis included: determining the projected net operating cash flows by considering the charter revenues from existing time charters for the fixed fleet days (the Company’s remaining charter agreement rates) and an estimated daily time charter equivalent for the unfixed days (based on three-year average historical time charter rates) over the remaining lease term, net of brokerage and address commissions excluding days of scheduled off-hires (for the bareboat chartered-in vessels), management fees for vessel operating expenses in accordance with the terms of management agreement (assuming an annual increase of 3.0% every second year for the bareboat chartered-in vessels). As of December 31, 2020 and 2019, the Company’s impairment assessments indicated that the undiscounted projected net operating cash flows determined for each asset group exceeded their carrying value. The impairment assessments performed as of December 31, 2020 and 2019 did not result in impairment charges. (y) Financial Instruments and Fair Value A financial instrument's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. In determining the appropriate levels, the Company performs a detailed analysis of the assets and liabilities that are subject to guidance on Fair Value Measurements. (z) Recent Accounting Pronouncements In March 2020, the FASB issued ASU 2020-4, “Reference Rate Reform (Topic 848)” (“ASU 2020-4”), which provides optional guidance, intended to ease the potential burden in accounting for the expected discontinuation of LIBOR as a reference rate in the financial markets. The guidance can be applied to modifications made to certain contracts to replace LIBOR with a new reference rate. The guidance, if elected, will permit entities to treat such modifications as the continuation of the original contract, without any required accounting reassessments or remeasurements. The ASU 2020-4 was effective for the Company beginning on March 12, 2020 and the Company will apply the amendments prospectively through December 31, 2022. There was no impact to the Company’s consolidated financial statements as a result of adopting this standard update. Currently, the Company has various contracts that reference LIBOR and is assessing how this standard may be applied to specific contract modifications. In October 2018, the Financial Accounting Standards Board (“FASB”) issued ASU 2018-17, Consolidation (Topic 810): “Targeted Improvements to Related Party Guidance for Variable Interest Entities” (“

Segment Reporting [Abstract]
Segment information	NOTE 13 SEGMENT INFORMATION Segment information Navios Partners reports financial information and evaluates its operations by charter revenues. Navios Partners does not use discrete financial information to evaluate operating results for each type of charter or by sector. As a result, management reviews operating results solely by revenue per day and operating results of the fleet and thus Navios Partners has determined that it operates under one reportable segment. The following table sets out operating revenue by geographic region for Navios Partners' reportable segment. Revenue is allocated on the basis of the geographic region in which the customer is located. Drybulk and containerships operate worldwide. Revenues from specific geographic region, which contribute over 10% of total revenue, are disclosed separately. Revenue by Geographic Region Vessels operate on a worldwide basis and are not restricted to specific locations. Accordingly, it is not possible to allocate the assets of these operations to specific countries.

Income Tax Disclosure [Abstract]
Income taxes	NOTE 14 INCOME TAXES Income taxes Marshall Islands, Malta and Liberia do not impose a tax on international shipping income. Under the laws of Marshall Islands, Malta and Liberia, the countries of the vessel-owning subsidiaries' incorporation and vessels' registration, the vessel-owning subsidiaries are subject to registration and tonnage taxes, which have been included in vessel operating expenses in the accompanying Consolidated Statements of Operations. In accordance with the currently applicable Greek law, foreign flagged vessels that are managed by Greek or foreign ship management companies having established an office in Greece are subject to duties towards the Greek state, which are calculated on the basis of the relevant vessel's tonnage. The payment of said duties exhausts the tax liability of the foreign ship owning company and the relevant manager against any tax, duty, charge or contribution payable on income from the exploitation of the foreign flagged vessel. Pursuant to Section 883 of the Internal Revenue Code of the United States, U.S. source income from the international operation of ships is generally exempt from U.S. income tax if the company operating the ships meets certain incorporation and ownership requirements. Among other things, in order to qualify for this exemption, the company operating the ships must be incorporated in a country, which grants an equivalent exemption from income taxes to U.S. corporations. All the vessel-owning subsidiaries satisfy these initial criteria. In addition, these companies must meet an ownership test. The management of Navios Partners believes that this ownership test was satisfied prior to the IPO by virtue of a special rule applicable to situations where the ship operating companies are beneficially owned by a publicly traded company. Although not free from doubt, management also believes that the ownership test will be satisfied based on the trading volume and ownership of Navios Partners' units, but no assurance can be given that this will remain so in the future.

In March 2018, the Board determined to reinstate a distribution and any continued distribution will be at the discretion of the Company’s Board of Directors, taking into consideration the terms of its partnership agreement. There is no guarantee that the Company will pay the quarterly distribution on the common units in any quarter. The amount of distributions paid under its policy and the decision to make any distribution is determined by the Company’s board of directors, taking into consideration the terms of its partnership agreement. The Company is prohibited from making any distributions to unitholders if it would cause an event of default, or an event of default exists, under its existing credit facilities. There is incentive distribution rights held by Navios GP L.L.C., which are analyzed as follows: Cash distributions and earnings per unit - Schedule Of Incentive Distributions Made To General Partners Or Unitholders By Distribution Marginal Percentage Total Quarterly Distribution Common Incentive General Minimum Quarterly Distribution up to $ 5.25 98% — 2% First Target Distribution up to $ 6.0375 98% — 2% Second Target Distribution above $ 6.0375 6.5625 85% 13% 2% Third Target Distribution above $ 6.5625 7.875 75% 23% 2% Thereafter above $ 7.875 50% 48% 2% The first 98% of the quarterly distribution is paid to all common unitholders.

Basic earnings/(losses) per unit is determined by dividing net income/(loss) attributable to Navios Partners common unitholders by the weighted average number of common units outstanding during the period. Diluted earnings per unit is calculated in the same manner as basic earnings per unit, except that the weighted average number of outstanding units increased to include the dilutive effect of outstanding unit options or phantom units. Net loss per unit undistributed is determined by taking the distributions in excess of net income and allocating between common units and general partner units on a 98% 2% The calculations of the basic and diluted earnings per unit are presented below. Cash distribution and earnings per unit - Schedule of earnings per unit, Basic and Diluted Year Ended December 31, 2020 Year Ended December 31, 2019 Year Ended December 31, 2018 Net loss $ (68,541) $ (62,134) $ (13,081) Loss attributable to: Common unitholders $ (67,173) $ (60,899) $ (12,819) Weighted average units outstanding (basic and diluted) Common unitholders 10,966,518 10,830,959 10,823,591 Loss per unit (basic and diluted): Common unitholders $ (6.13) $ (5.62) $ (1.18) Earnings per unit - distributed (basic and diluted): Common unitholders $ 0.45 $ 1.22 $ 1.24 Loss per unit - undistributed (basic and diluted): Common unitholders $ (6.58) $ (6.84) $ (2.43) Potential common units of 92,699 146,541 210,274

Leases	NOTE 22 LEASES Leases Time charter out contracts and pooling arrangements The Company's contract revenues from time chartering and pooling arrangements are governed by ASC 842. Upon adoption of ASC 842, the timing and recognition of earnings from the time charter contracts and pool arrangements to which the Company is party did not change from previous practice. For further analysis, (see Note 2— Summary of Significant Accounting Policies). Bareboat charter-in contract On July 24, 2019, Navios Partners took delivery of the Navios Libra 2019 Panamax 82,011 ten year 6 Based on management estimates and market conditions, the lease term of this lease is being assessed at each balance sheet date. At lease commencement, the Company determines a discount rate to calculate the present value of the lease payments so that it can determine lease classification and measure the lease liability. In determining the discount rate to be used at lease commencement, the Company used its incremental borrowing rate as there was no implicit rate included in charter-in contracts that can be readily determinable. The incremental borrowing rate is the rate that reflects the interest a lessee would have to pay to borrow funds on a collateralized basis over a similar term and in a similar economic environment. The Company then applied the respective incremental borrowing rate based on the remaining lease term of the specific lease. As of July 24, 2019, Navios Partners' incremental borrowing rate was approximately 7% As of December 31, 2020 and December 31, 2019 the unamortized balance of the lease liability amounted $ 13,153 14,201 13,285 14,241 The Company recognizes the lease payments for its operating leases as charter hire on a straight-line basis over the lease term. Lease expense for the year ended December 31, 2020 amounted to $ 2,086 918 As of December 31, 2020 and 2019, the Company proceeded with step one of impairment assessment of the unamortized balance of the Right of use asset in relation to vessel Navios Libra. As the undiscounted projected net operating cash flows exceed the carrying value of the right-of-use asset, no impairment loss was recognized as of December 31, 2020 and 2019. The table below provides the total amount of lease payments on an undiscounted basis on the Company’s chartered-in contracts as of December 31, 2020: Leases Charter-in vessels in operation December 31, 2021 $ 2,172 December 31, 2022 2,132 December 31, 2023 2,081 December 31, 2024 2,086 December 31, 2025 2,081 December 31, 2026 and thereafter 7,141 Total $ 17,693 Operating lease liabilities, including current portion $ 13,153 Discount based on incremental borrowing rate $ 4,540 Sale and Lease Back Agreements During 2019 and 2018 the Company has entered into sale and leaseback agreements with unrelated third parties for five vessels of the Company's fleet. Navios Partners has purchase obligations to acquire the vessels at the end of the lease terms, consequently under ASC 842-40 the transfers of the vessels were determined to be failed sales and were treated as financing transactions. The vessels were not derecognized and continue to be depreciated over their respective useful lives, and tested for impairment as per Company's policy (see Note 10— Borrowings).

Impairment of Long Lived Assets	(j) Impairment of Long Lived Assets Undiscounted projected net operating cash flows are determined for each asset group and compared to the carrying value of the vessel, the unamortized portion of deferred drydock and special survey costs related to the vessel and the related carrying value of the intangible assets with respect to the time charter agreement attached to that vessel or the carrying value of deposits for newbuildings. Within the shipping industry, vessels are customarily bought and sold with a charter attached. The value of the charter may be favorable or unfavorable when comparing the charter rate to then current market rates. The loss recognized either on impairment (or on disposition) will reflect the excess of carrying value over fair value (selling price) for the vessel asset group. During the fourth quarter of fiscal year 2020, the Company concluded that events occurred and circumstances had changed, which indicated that potential impairment of Navios Partners' long-lived assets may exist. These indicators included volatility in the charter market as well as the potential impact the current marketplace may have on the Company’s future operations. As a result, an impairment assessment of long-lived assets (step one) was performed. The Company determined the undiscounted projected net operating cash flows for each vessel and compared it to the vessels' carrying value together with the carrying value of deferred drydock and special survey costs related to the vessel and the carrying value of the related intangible assets, if applicable. The significant factors and assumptions the Company used in the undiscounted projected net operating cash flow analysis included: determining the projected net operating cash flows by considering the charter revenues from existing time charters for the fixed fleet days (Navios Partners' remaining charter agreement rates) and an estimated daily time charter equivalent for the unfixed days (based on a combination of one-year average historical time charter rates for the first year and ten-year average historical one-year time charter rates for the remaining period), over the remaining economic life of each vessel, net of brokerage and address commissions, and excluding days of scheduled off-hires, management fees as determined by the Management Agreement in effect until December 2024 and thereafter assuming an increase of 3.0% 98.6% Where the undiscounted projected net operating cash flows do not exceed the carrying value of an asset group, management proceeded to perform step two of the impairment assessment. In step two of the impairment assessment, the Company determined fair value of its vessels through a combination of a discounted cash flow analysis utilizing market participant assumptions from available market data and third-party valuations from independent ship brokers performed on an individual vessel basis. The significant factors and assumptions used by management in determining fair value of vessels included those in developing the projected net operating cash flows over the remaining economic life of each vessel and the discount rate. As of December 31, 2020, the Company’s assessment concluded that step two of the impairment analysis was required for certain of its vessels held and used, as the undiscounted projected net operating cash flows did not exceed the carrying value. As a result, the Company recorded an impairment loss of $ 50,991 As of December 31, 2019, the Company’s assessment concluded that step two of the impairment analysis was required for certain of its vessels held and used, as the undiscounted projected net operating cash flows did not exceed the carrying value. As a result, the Company recorded an impairment loss of $ 29,335 As of December 31, 2018, the Company’s assessment concluded that step two of the impairment analysis was not required for its vessels held and used, as the undiscounted projected net operating cash flows exceeded the carrying value. As of June 30, 2020, the Company concluded that events and circumstances triggered the existence of potential impairment of its containerships. These indicators included volatility in the charter market and market values for containerships. As a result, the Company performed step one of the impairment assessment of its containerships by comparing the undiscounted projected net operating cash flows for each vessel to its carrying value. As of June 30, 2020, the Company’s assessment concluded that step two of the impairment analysis was required for three containerships held and used, as the undiscounted projected net operating cash flows did not exceed the carrying value. As a result, the Company recorded an impairment loss of $ 6,800 During the years ended December 31, 2020, 2019 and 2018, an impairment loss of $ 13,786 7,345 44,344 The total impairment loss recognized amounted to $ 71,577 36,680 44,344

Management, after considering various indicators, performed an impairment test which included intangible assets as described in paragraph (j) above. As of December 31, 2020, 2019 and 2018 there was no impairment of intangible assets.

Revenue and Expense Recognition	(q) Revenue and Expense Recognition : The Company's contract revenues from time chartering and pooling arrangements are governed by ASU 2016-02 (ASC 842) “Leases”. Upon adoption of ASC 606 and ASC 842, the timing and recognition of earnings from the pool arrangements and time charter contracts to which the Company is party did not change from previous practice. The Company has determined to recognize lease revenue as a combined single lease component for all time charters (operating leases) as the related lease component and non-lease components will have the same timing and pattern of the revenue recognition of the combined single lease component. The performance obligations in a time charter contract are satisfied over term of the contract beginning when the vessel is delivered to the charterer until it is redelivered back to the Company. As a result of the adoption of these standards, there was no effect on the Company's retained earnings, as at January 1, 2018. Revenue from time chartering Revenues from time chartering of vessels are accounted for as operating leases and are thus recognized on a straight line basis as the average lease revenue over the rental periods of such charter agreements, as service is performed. A time charter involves placing a vessel at the charterers' disposal for a period of time during which the charterer uses the vessel in return for the payment of a specified daily hire rate. Short period charters for less than three months are referred to as spot-charters. Charters extending three months to a year are generally referred to as medium-term charters. All other charters are considered long-term. Under time charters, operating costs such as for crews, maintenance and insurance are typically paid by the owner of the vessel. Revenue from time chartering of vessels amounted to $ 218,809 204,920 215,877 Revenue from voyage contracts The Company's revenues earned under voyage contracts (revenues for the transportation of cargo) were previously recognized ratably over the estimated relative transit time of each voyage. A voyage was deemed to commence when a vessel was available for loading and was deemed to end upon the completion of the discharge of the current cargo. Estimated losses on voyages are provided for in full at the time such losses become evident. Under a voyage charter, a vessel is provided for the transportation of specific goods between specific ports in return for payment of an agreed upon freight per ton of cargo. Upon adoption of ASC 606, the Company recognizes revenue ratably from port of loading to when the charterer's cargo is discharged as well as defer costs that meet the definition of “costs to fulfill a contract” and relate directly to the contract. During 2017, no freight voyage existed and therefore, there was no impact on the Company's retained earnings as at January 1, 2018. Revenue from voyage contracts amounted to $ 3,754 9,416 9,660 Pooling arrangements For vessels operating in pooling arrangements, the Company earns a portion of total revenues generated by the pool, net of expenses incurred by the pool. The amount allocated to each pool participant vessel, including the Company's vessels, is determined in accordance with an agreed-upon formula, which is determined by points awarded to each vessel in the pool based on the vessel's age, design and other performance characteristics. Revenue under pooling arrangements is accounted for as variable rate operating leases on the accrual basis and is recognized when an agreement with the pool exists, price is fixed, service is provided and the collectability is reasonably assured. The allocation of such net revenue may be subject to future adjustments by the pool however, such changes are not expected to be material. The Company recognizes net pool revenue on a monthly and quarterly basis, when the vessel has participated in a pool during the period and the amount of pool revenue can be estimated reliably based on the pool report. Revenue from vessels operating in pooling arrangements amounted to $ 4,208 5,043 5,817 Revenue from profit-sharing Profit-sharing revenues are calculated at an agreed percentage of the excess of the charterer's average daily income (calculated on a quarterly or half-yearly basis) over an agreed amount and accounted for on an accrual basis based on provisional amounts and for those contracts that provisional accruals cannot be made due to the nature of the profit sharing elements, these are accounted for on the actual cash settlement or when such revenue becomes determinable. Profit sharing revenue for the years ended December 31, 2020, 2019 and 2018 amounted to 0 0 7 Revenues are recorded net of address commissions. Address commissions represent a discount provided directly to the charterers based on a fixed percentage of the agreed upon charter or freight rate. Since address commissions represent a discount (sales incentive) on services rendered by the Company and no identifiable benefit is received in exchange for the consideration provided to the charterer, these commissions are presented as a reduction of revenue. Deferred Revenue and Cash Received in Advance: Time Charter and Voyage Expenses: Direct Vessel Expenses: Prepaid Voyage Costs: Vessel operating expenses (management fees): 4.23 4.33 5.25 6.70 7.40 8.75 In August 2019, Navios Partners extended the duration of its Management Agreement with the Manager until January 1, 2025. In addition, management fees are fixed for two years commencing from January 1, 2020 at: (a) $ 4.35 4.45 5.41 6.90 0.05 3% Following the liquidation of Navios Europe I, Navios Partners acquired three Sub-Panamax and two Panamax Containerships. As per the Management Agreement, as amended in December 2019, management fees are fixed for two years commencing from January 1, 2020 at $ 6.1 0.05 3% Drydocking expenses are reimbursed at cost for all vessels. For the years ended December 31, 2020 and 2019 certain extraordinary fees and costs related to regulatory requirements, including ballast water treatment system installation and exhaust gas cleaning system installation under Company's management agreement, amounted to $ 3,366 16,313 Total vessel operating expenses for each of the years ended December 31, 2020, 2019 and 2018 amounted to $ 93,732 68,188 68,871 General and Administrative Expenses: Total general and administrative expenses charged by the Manager for each of the years ended December 31, 2020, 2019 and 2018 amounted to $ 13,708 10,406 9,344
Financial Instruments	(r) Financial Instruments Financial Risk Management: Credit risk: Financial instruments that potentially subject Navios Partners to concentrations of credit risk are accounts receivable and cash and cash equivalents. Navios Partners does not believe its exposure to credit risk is likely to have a material adverse effect on its financial position, results of operations or cash flows. For the year ended December 31, 2020 HMM, Singapore Marine and Cargill represented approximately 23.4% 19.5% 11.4% 25.9% 12.3% 10.9% 24.5% Liquidity Risk: Foreign Exchange Risk:
Cash Distribution	(s) Cash Distribution As per the Partnership Agreement, within 45 days following the end of each quarter, to the extent and as may be declared by the Board, an amount equal to 100% of Available Cash with respect to such quarter shall be distributed to the partners as of the record date selected by the Board of Directors. Available Cash: • less the amount of cash reserves established by the Board of Directors to: • provide for the proper conduct of the business (including reserve for maintenance and replacement capital expenditures); • comply with applicable law, any of Navios Partners' debt instruments, or other agreements; or • provide funds for distributions to the unitholders and to the general partner for any one or more of the next four quarters; • plus all cash on hand on the date of determination of Available Cash for the quarter resulting from working capital borrowings made after the end of the quarter. Working capital borrowings are generally borrowings that are made under any revolving credit or similar agreement used solely for working capital purposes or to pay distributions to partners. Available Cash is a quantitative measure used in the publicly traded partnership investment community to assist in evaluating a partnership's ability to make quarterly cash distributions. Available Cash is not required by U.S. GAAP and should not be considered a substitute for net income, cash flow from operating activities and other operations or cash flow statement data prepared in accordance with accounting principles generally accepted in the United States or as a measure of profitability or liquidity. Cash distributions are recorded in the Company's financial statements in the period in which they are declared.

Leases	(x) Leases For charters classified as finance leases the minimum lease payments are recorded as the gross investment in the lease. The difference between the gross investment in the lease and the sum of the present values of the two components of the gross investment is recorded as unearned income which is amortized to income over the lease term as finance lease interest income to produce a constant periodic rate of return on the net investment in the lease. For charters classified as operating leases where Navios Partners is regarded as the lessor,(see Note 2(q) — Summary of Significant Accounting Policies). In cases of lease agreements where the Company acts as the lessee, the Company recognizes a right-of-use asset and a corresponding lease liability on the consolidated balance sheet. For finance leases, interest expense is determined using the effective interest method and amortization on the right-of-use asset is recognized on a straight line basis over the lease term. For charters classified as operating leases, lease expense is recognized on a straight line basis over the rental periods of such charter agreements, by adding interest expense to the amortization of the right-of-use asset. The expense is included in the caption “Time charter and voyage expenses” in the consolidated statement of Operations. In cases of sale and leaseback transactions, if the transfer of the asset to the lessor does not qualify as a sale, then the transaction constitutes a failed sale and leaseback and is accounted for as a financing transaction. For a sale to have occurred, the control of the asset would need to be transferred to the buyer, and the buyer would need to obtain substantially all the benefits from the use of the asset. Operating lease assets used by Navios Partners are reviewed periodically for potential impairment whenever events or changes in circumstances indicate that the carrying amount may not be fully recoverable. Measurement of the impairment loss is based on the fair value of the asset. Navios Partners determines the fair value of its assets based on management estimates and assumptions by making use of available market data. In evaluating carrying values of operating lease assets, certain indicators of potential impairment are reviewed, such as undiscounted projected operating cash flows, business plans and overall market conditions. Undiscounted projected net operating cash flows are determined for each asset group and compared to the carrying value of the operating lease asset and the carrying value of deposits for the option to acquire a vessel including expenses and interest. If step two of the impairment analysis is required, the analysis includes the use of the discounted cash flow which comprises various assumptions, including the Company’s WACC. During the fourth quarter of fiscal year 2020, management concluded that events occurred and circumstances had changed, which indicated that potential impairment of Navios Partners’ operating lease assets might exist. These indicators included volatility in the charter market as well as the potential impact the current marketplace may have on the Company’s future operations As a result, an impairment assessment of operating lease assets (step one) was performed. The Company determined undiscounted projected net operating cash flows for each chartered-in vessel and compared it to operating lease asset’s carrying value together with the carrying value of deposits for the option to acquire a vessel including expenses and interest. The significant factors and assumptions used in the undiscounted projected net operating cash flow analysis included: determining the projected net operating cash flows by considering the charter revenues from existing time charters for the fixed fleet days (the Company’s remaining charter agreement rates) and an estimated daily time charter equivalent for the unfixed days (based on three-year average historical time charter rates) over the remaining lease term, net of brokerage and address commissions excluding days of scheduled off-hires (for the bareboat chartered-in vessels), management fees for vessel operating expenses in accordance with the terms of management agreement (assuming an annual increase of 3.0% every second year for the bareboat chartered-in vessels). As of December 31, 2020 and 2019, the Company’s impairment assessments indicated that the undiscounted projected net operating cash flows determined for each asset group exceeded their carrying value. The impairment assessments performed as of December 31, 2020 and 2019 did not result in impairment charges.
Financial Instruments and Fair Value	(y) Financial Instruments and Fair Value A financial instrument's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. In determining the appropriate levels, the Company performs a detailed analysis of the assets and liabilities that are subject to guidance on Fair Value Measurements.
Recent Accounting Pronouncements	(z) Recent Accounting Pronouncements In March 2020, the FASB issued ASU 2020-4, “Reference Rate Reform (Topic 848)” (“ASU 2020-4”), which provides optional guidance, intended to ease the potential burden in accounting for the expected discontinuation of LIBOR as a reference rate in the financial markets. The guidance can be applied to modifications made to certain contracts to replace LIBOR with a new reference rate. The guidance, if elected, will permit entities to treat such modifications as the continuation of the original contract, without any required accounting reassessments or remeasurements. The ASU 2020-4 was effective for the Company beginning on March 12, 2020 and the Company will apply the amendments prospectively through December 31, 2022. There was no impact to the Company’s consolidated financial statements as a result of adopting this standard update. Currently, the Company has various contracts that reference LIBOR and is assessing how this standard may be applied to specific contract modifications. In October 2018, the Financial Accounting Standards Board (“FASB”) issued ASU 2018-17, Consolidation (Topic 810): “Targeted Improvements to Related Party Guidance for Variable Interest Entities” (“ASU 2018-17”). ASU 2018-17 provides that indirect interests held through related parties in common control arrangements should be considered on a proportional basis for determining whether fees paid to decision makers and service providers are variable interests. This is consistent with how indirect interests held through related parties under common control are considered for determining whether a reporting entity must consolidate a VIE. For public business entities the amendments were effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption was permitted. The Company has adopted this standard update as of January 1, 2020. The adoption of this new accounting guidance did not have a material effect on the Company’s consolidated financial statements. In August 2018, FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement”. This update modifies the disclosure requirements on fair value measurements. ASU 2018-13 was effective for fiscal years beginning after December 15, 2019, and earlier adoption was permitted. The Company has adopted this standard update as of January 1, 2020. The adoption of this new accounting guidance did not have a material effect on the Company’s consolidated financial statements. In June 2016, FASB issued ASU No. 2016-13, “Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”. This ASU amends the accounting for credit losses on available-for-sale debt securities, purchased financial assets with credit deterioration and clarifies that impairment of receivables arising from operating leases should be accounted for in accordance with Topic 842, Leases. In addition, these amendments require the measurement of all expected credit losses for financial assets, including trade accounts receivable, held at the reporting date based on historical experience, current conditions, and current expectations of future economic conditions based on reasonable and supportable forecasts. The Company has adopted this standard update as of January 1, 2020. This new guidance did not have a material impact on the Company’s consolidated financial statements, as the majority of its Accounts receivable, net relates to receivables arising from operating leases and are scoped out of the new standard. The Company has assessed all the expected credit losses of its financial assets and the adoption of this ASU did not have a material impact on the Company’s consolidated financial statements.

Concentration Risk, Customer	Concentration of credit risk with respect to accounts receivable is limited due to the Company's large number of customers, who are internationally dispersed and have a variety of end markets in which they sell. Due to these factors, management believes that no additional credit risk beyond amounts provided for collection losses is inherent in the Company's trade receivables.
