Summary of Significant Accounting Policies	Dec. 31, 2021
Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Summary of Significant Accounting Policies (a) Basis of presentation : The accompanying consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Based on internal forecasts and projections that take into account reasonably possible changes in our trading performance, management believes that the Company has adequate financial resources to continue in operation and meet its financial commitments, including but not limited to capital expenditures, cash from sale of vessels and debt service obligations, for a period of at least twelve months from the date of issuance of these consolidated financial statements. Accordingly, the Company continues to adopt the going concern basis in preparing its financial statements. Reverse Stock Split: On April 25, 2019, the Company's unitholders approved a 1-for-15 reverse stock split of the Company's outstanding common and general partner units, which was effected on May 21, 2019. The effect of the reverse stock split was to combine 15 units of outstanding common units into one new unit, with no change in authorized units or par value per unit, and to reduce the number of common units outstanding from approximately 164.7 million units to approximately 11 .0 million units. 983 common units were issued in connection with the reverse stock split. All issued and outstanding common units contained in the financial statements, in accordance with Staff Accounting Bulletin Topic 4C, have been retroactively adjusted to reflect the reverse split for all periods presented. (b) Principles of consolidation : The accompanying consolidated financial statements include Navios Partners' wholly owned subsidiaries incorporated under the laws of Marshall Islands, Malta, Cayman Islands and Liberia from their dates of incorporation or from the date of acquiring control, for chartered-in vessels, from the dates charter-in agreements were in effect. All significant inter-company balances and transactions have been eliminated in Navios Partners' consolidated financial statements. Navios Partners also consolidates entities that are determined to be variable interest entities (“VIE”) as defined in the accounting guidance, if it determines that it is the primary beneficiary. A VIE is defined as a legal entity where either (i) equity interest holders as a group lack the characteristics of a controlling financial interest, including decision making ability and an interest in the entity's residual risks and rewards, (ii) the equity holders have not provided sufficient equity investment to permit the entity to finance its activities without additional subordinated financial support, or (iii) the voting rights of some investors are not proportional to their obligations to absorb the expected losses of the entity, their rights to receive the expected residual returns of the entity, or both and substantially all of the entity's activities either involve or are conducted on behalf of an investor that has disproportionately few voting rights. Subsidiaries: The accompanying consolidated financial statements include the following entities: Summary of Significant Accounting Policies - Entities included in consolidation Statements of Operations Company name Vessel name Country of incorporation 2021 2020 2019 Libra Shipping Enterprises Corporation — Marshall Is. 1/01 – 12/31 1/01 – 12/31 1/01 – 12/31 Alegria Shipping Corporation Navios Alegria Marshall Is. 1/01 – 12/31 1/01 – 12/31 1/01 – 12/31 Felicity Shipping Corporation — Marshall Is. 1/01 – 12/31 1/01 – 12/31 1/01 – 12/31 Gemini Shipping Corporation — Marshall Is. 1/01 – 12/31 1/01 – 12/31 1/01 – 12/31 Galaxy Shipping Corporation (4) — Marshall Is. 1/01 – 12/31 1/01 – 12/31 1/01 – 12/31 Aurora Shipping Enterprises Ltd.

Investments in Affiliates: 20 50 6,900 Affiliates included in the financial statements accounted for under the equity method: 35.7 % as of December 31, 2020). Following the completion of the NMCI Merger (as defined herein), as of March 31, 2021, Navios Containers was acquired by Navios Partners and ownership was 100 5 % through the date of its liquidation on December 13, 2019; and (iii) Navios Europe II and its subsidiaries with an ownership interest of 5 % through the date of its liquidation on June 29, 2020 (see Note 18 — Transactions with related parties and affiliates, Note 20 – Investment in affiliates and Note 3 – Acquisition of Navios Containers and Navios Acquisition). (c) Use of Estimates : The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. On an on-going basis, management evaluates the estimates and judgments, including those related to uncompleted voyages, future drydock dates, the selection of useful lives for tangible assets and scrap value expected future cash flows from long-lived assets to support impairment tests, provisions necessary for accounts receivable, valuation of intangible assets and liabilities acquired in business combinations,provisions for legal disputes, and contingencies and the valuation estimates inherent in the deconsolidation gain. Management bases its estimates and judgments on historical experience and on various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from those estimates under different assumptions and/or conditions. (d) Cash and Cash Equivalents : Cash and cash equivalents consist of cash on hand, deposits held on call with banks, and other short-term liquid investments with original maturities of three months or less. (e) Restricted Cash : Restricted cash, at each of December 31, 2021 and December 31, 2020, included $ 9,979 and $ 6,152 , respectively, which related to amounts held in retention accounts in order to service debt and interest payments, as required by certain of Navios Partners' credit facilities and financial liabilities. Also, as of December 31, 2020, restricted cash included $ 5,273 as cash collateral to the NIBC Credit Facility, due to the release of the Navios Soleil. (f) Accounts Receivable, Net : Accounts receivable includes receivables from charterers for hire, freight and demurrage billings. On January 1, 2020, the Company adopted Accounting Standards Update 2016-13, “Financial Instruments - Credit Losses” (“ASC 326”). At each balance sheet date, the Company maintains an allowance for credit losses for expected uncollectible accounts receivable ( see Note 5 - Accounts Receivable, net). Navios Partners has filed claims for lost revenues in connection with the 2016 filing by Hanjin for rehabilitation, which was later followed by entry into liquidation in 2017. In October 2020, the bankruptcy court ruled against one of the two claims filed by the Company. The Company has fully provided for these amounts in its books. The allowance for credit losses was $ 2,990 as of December 31, 2021 and 2020, respectively. (g) Inventories : Inventories, which are comprised of: (i) bunkers (when applicable) on board of the vessels, valued at cost as determined on the first-in, first-out basis; and (ii) lubricants and stock provisions on board of the vessels as of the balance sheet date, valued at cost as determined on the first-in, first-out basis. (h) Vessels, Net : Vessels are stated at historical cost, which consists of the contract price and pre-delivery costs incurred during the construction and delivery of newbuildings, including capitalized interest, and any material expenses incurred upon acquisition (improvements and delivery expenses) of second hand vessels. Vessels acquired in an asset acquisition or in a business combination are recorded at fair value. The fair value of the vessels is determined based on vessel valuations, from independent third party shipbrokers. Subsequent expenditures for major improvements and upgrades are capitalized, provided they appreciably extend the life, increase the earnings capacity or improve the efficiency or safety of the vessels. The cost and related accumulated depreciation of assets retired or sold are removed from the accounts at the time of sale or retirement and any gain or loss is included in the accompanying Consolidated Statements of Operations. Expenditures for routine maintenance and repairs are expensed as incurred. Depreciation is computed using the straight line method over the useful life of the vessels, after considering the estimated residual value. Management estimates the residual values of the Company’s drybulk, containerships and tankers based on a scrap value cost of steel times the weight of the ship noted in lightweight ton (“LWT”). Residual values are periodically reviewed and revised to recognize changes in conditions, new regulations or other reasons. Revisions of residual values affect the depreciable amount of the vessels and affect depreciation expense in the period of the revision and future periods. The estimated scrap rate used to calculate the vessel’s scrap value is $ 340 per LWT Management estimates the useful life of the Company’s vessels to be 25 years for drybulk and tanker vessels and 30 years from the containerships, respectively from the original construction. However, when regulations place limitations over the ability of a vessel to trade on a worldwide basis, its useful life is re-estimated to end at the date such regulations become effective. An increase in the useful life of a vessel or in its residual value would have the effect of decreasing the annual depreciation charge and extending it into later periods. A decrease in the useful life of a vessel or in its residual value would have the effect of increasing the annual depreciation charge. (i) Assets Held for Sale : It is the Company's policy to dispose of vessels and other fixed assets when suitable opportunities occur and not necessarily to keep them until the end of their useful life. The Company classifies assets and disposal groups as being held for sale when the following criteria are met: management has committed to a plan to sell the vessel (disposal group); the asset (disposal group) is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of vessels; an active program to locate a buyer and other actions required to complete the plan to sell the asset (disposal group) have been initiated; the sale of the asset (disposal group) is probable and transfer of the asset (disposal group) is expected to qualify for recognition as a completed sale within one year; the asset (disposal group) is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. Long-lived assets or disposal groups classified as held for sale are measured at the lower of their carrying amount or fair value less cost to sell. These vessels are not depreciated once they meet the criteria to be held for sale. No assets were classified as held for sale as of December 31, 2021 and 2020. (j) Impairment of Long Lived Assets : Vessels, other fixed assets and other long lived assets held and used by Navios Partners are reviewed periodically for potential impairment whenever events or changes in circumstances indicate that the carrying amount of a particular asset may not be fully recoverable. Navios Partners' management evaluates the carrying amounts and periods over which long-lived assets are depreciated to determine if events or changes in circumstances have occurred that would require modification to their carrying values or useful lives. Measurement of the impairment loss is based on the fair value of the asset. Navios Partners determines the fair value of its assets on the basis of management estimates and assumptions by making use of available market data and taking into consideration third party valuations performed on an individual vessel basis. In evaluating useful lives and carrying values of long-lived assets, certain indicators of potential impairment, are reviewed such as undiscounted projected operating cash flows, vessel sales and purchases, 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 vessel, the unamortized portion of deferred drydock and special survey costs, ballast water treatment system costs, exhaust gas cleaning system costs and other capitalized items, if any, 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 the 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. The management of the Company has considered various indicators, including but not limited to the market price of its long-lived assets, its contracted revenues and cash flows and the economic outlook. As of December 31, 2021, the Company concluded that events and circumstances did not trigger the existence of potential impairment of its vessels and the related intangible assets and that step one of the impairment analysis was not required. As of December 31, 2020, the Company concluded that events occurred and circumstances had changed, which indicated that potential impairment of Navios Partners' long-lived 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

Acquisition of Navios Containers and Navios Acquisition	Dec. 31, 2021
Business Combination and Asset Acquisition [Abstract]
Acquisition of Navios Containers and Navios Acquisition	NOTE 3 – ACQUISITION OF NAVIOS CONTAINERS AND NAVIOS ACQUISITION Acquisition of Navios Containers and Navios Acquisition ACQUISITION OF NAVIOS CONTAINERS On March 31, 2021 , Navios Partners completed the merger (the “NMCI Merger”) contemplated by the Agreement and Plan of Merger (the “NMCI Merger Agreement”), dated as of December 31, 2020 , by and amongst Navios Partners, its direct wholly-owned subsidiary NMM Merger Sub LLC (“Merger Sub”), Navios Maritime Containers L.P. (“Navios Containers”) and Navios Maritime Containers GP LLC, Navios Containers’ general partner. Pursuant to the NMCI Merger Agreement, Merger Sub merged with and into Navios Containers, with Navios Containers continuing as the surviving partnership. As a result of the NMCI Merger, Navios Containers became a wholly-owned subsidiary of Navios Partners. Pursuant to the terms of the NMCI Merger Agreement, each outstanding common unit of Navios Containers that was held by a unitholder other than Navios Partners, Navios Containers and their respective subsidiaries was converted into the right to receive 0.39 of a common unit of Navios Partners. Navios Partners accounted for the NMCI Merger “as a business combination achieved in stages”, which results in the application of the “acquisition method,” as defined under ASC 805, Business Combinations. Navios Partners’ previously held equity interest in Navios Containers was remeasured to its fair value at March 31, 2021, the date the controlling interest was acquired and the resulting gain was recognized in earnings. Under the acquisition method, the fair value of the consideration paid by Navios Partners in connection with the transaction was allocated to Navios Containers’ net assets based on their estimated fair values at the date of the completion of the NMCI Merger. The excess of the fair value of the identifiable net assets acquired of $ 342,674 over the total purchase price consideration of $ 298,621 , resulted in a bargain purchase gain of $ 44,053 . The transaction resulted in a bargain purchase gain as a result of the share price of Navios Containers trading at a discount to their net asset value (“NAV”). The fair value of the vessels was determined based on vessel valuations, obtained from independent third party shipbrokers, which are among other things, based on recent sales and purchase transactions of similar vessels. The fair value of the unfavorable lease terms (intangible liabilities) was determined by reference to market data and the discounted amount of expected future cash flows. The key assumptions that were used in the discounted cash flow analysis were as follows: (i) the contracted charter rate of the acquired charter over the remaining lease term compared to (ii) the current market charter rates for a similar contract and (iii) discounted using the Company’s relevant discount factor of 8.89 %. As of March 31, 2021, Navios Partners previously held interest of 35.7 % in Navios Containers was remeasured to a fair value of $ 106,997 , determined using the closing price per common unit of $9.23 of NMCI as of the closing date of the NMCI merger, resulting in revaluation gain of $ 75,387 which along with the equity gain of $ 5,452 from the operations of Navios Containers upon the closing date aggregate to a gain on acquisition of control in the amount of $ 80,839 and is presented in, “Equity in net earnings of affiliated companies”, in the accompanying Consolidated Statement of Operations. The acquisition of the remaining interest of 64.3 % through the issuance of newly issued common units in Navios Partners was recorded at a fair value of $ 191,624 on the basis of 8,133,452 common units issued at a closing price per common unit of $ 23.56 as of the closing date of the NMCI Merger. Upon completion of the NMCI Merger on March 31, 2021, beginning from April 1, 2021, the results of operations of Navios Containers are included in Navios Partners’ Consolidated Statements of Operations. Total time charter and voyage revenues and net income of Navios Containers for the period from April 1, 2021 to December 31, 2021 included in the Consolidated Statement of Operations amounted to $ 168,322 182,479 Transaction costs amounted to $ 247 and have been expensed in the Consolidated Statement of Operations under the caption “Transaction costs” in the accompanying Consolidated Statements of Operations. The following table summarizes the consideration exchanged and the fair value of assets acquired and liabilities assumed on March 31, 2021: Acquisition of Navios Containers - Schedule of recognized identified assets acquired and liabilities Purchase price: Fair value of previously held interest (35.7%) $ 106,997 Equity issuance (8,133,452 Navios Partners units * $23.56) 191,624 Total purchase price 298,621 Fair value of assets acquired and liabilities assumed: Vessels 770,981 Current assets (including cash of $10,282) 29,033 Unfavorable lease terms (224,490) Long term debt and financial liabilities assumed (including current portion) (227,434) Current liabilities (5,416) Fair value of net assets acquired 342,674 Bargain gain $ 44,053 The acquired intangible, listed below, as determined at the acquisition date and are amortized under the straight line method over the period indicated below: Acquisition of Navios Containers - Lease Future Amortization Income Within One Year Year Two Year Three Year Four Year Five Year Six Total Time charters with unfavorable lease terms $ (126,710) (52,501) (20,431) (12,462) (11,445) (941) $ (224,490) Intangible liabilities subject to amortization are amortized using straight line method over their estimated useful lives to their estimated residual value of zero. The following is a summary of the acquired identifiable intangible liability: Acquisition of Navios Containers - Acquired finite lived intangible Amount Description Unfavorable lease terms $ (224,490) ACQUISITION OF NAVIOS ACQUISITION On August 25, 2021 44,117,647 newly issued shares of Navios Acquisition, thereby acquiring a controlling interest of 62.4 % in Navios Acquisition, and the results of operations of Navios Acquisition are included in Navios Partners’ consolidated statements of operations commencing on August 26, 2021. On October 15, 2021, Navios Partners completed the merger with Navios Acquisition (the “NNA Merger” and together with the NMCI Merger, the “Mergers”) and as a result thereof, Navios Acquisition became a wholly-owned subsidiary of Navios Partners. Each outstanding share of common stock of Navios Acquisition that was held by a stockholder other than Navios Partners was converted into the right to receive 0.1275 of a common unit of Navios Partners. As a result of the NNA Merger, 3,388,226 Navios Partners accounted for the control obtained “as a business combination”, which resulted in the application of the “acquisition method,” as defined under ASC 805, Business Combinations, as well as the recognition of the equity interest in Navios Acquisition not held by Navios Partners to its fair value at the date the controlling interest is acquired by Navios Partners as noncontrolling interest on the consolidated balance sheet. The excess of the fair value of Navios Acquisition’s identifiable net assets acquired of $ 211,597 over the fair value of the consideration transferred of $ 150,000 and the fair value of the noncontrolling interest of $ 57,635 , resulted in a bargain gain upon obtaining control of $ 3,962 . The fair value of the consideration of $ 150,000 has been treated as deemed contribution with an equal increase in total partner’s capital. The fair value of the noncontrolling interest was determined by using the Navios Acquisition’s closing price of $ 2.17 as of August 25, 2021 (date of obtaining control). The fair value of the vessels was determined based on vessel valuations, obtained from independent third party shipbrokers, which are among other things, based on recent sales and purchase transactions of similar vessels. The fair value of the favorable and unfavorable lease terms (intangible assets and liabilities) were determined by reference to market data and the discounted amount of expected future cash flows. The key assumptions that were used in the discounted cash flow analysis were as follows: (i) the contracted charter rate of the acquired charter over the remaining lease term compared to (ii) the current market charter rates for a similar contract and (iii) discounted using the Company’s relevant discount factor of 10.43 %. Total time charter and voyage revenues and net loss of Navios Acquisition for the period from August 26, 2021 to December 31, 2021 included in the Consolidated Statement of Operations amounted to $ 82,477 17,946 Transaction costs amounted to $ 10,192 presented under the caption “Transaction costs” in the accompanying Consolidated Statements of Operations. The following table summarizes the fair value of the consideration transferred the fair value of assets acquired and liabilities assumed and the fair value of the noncontrolling interest in Navios Acquisition assumed on August 25, 2021: Acquisition of Navios Acquisition - Schedule of recognized identified assets acquired and liabilities Purchase consideration: Fair value of the consideration $ 150,000 Fair value of noncontrolling interest (37.6%) 57,635 Total purchase consideration 207,635 Fair value of Navios Acquisition’s assets acquired and liabilities assumed: Vessels 1,003,040 Other long-term assets 27,291 Operating lease assets 128,619 Current assets (including cash and restricted cash of $32,394) 64,180 Favorable lease terms 112,139 Unfavorable lease terms (6,529) Long term debt and financial liabilities assumed (including current portion) (811,608) Operating lease liabilities (including current portion) (128,619) Current liabilities (176,916) Fair value of Navios Acquisition’s net assets 211,597 Bargain gain upon obtaining control $ 3,962 The intangible assets and liabilities, listed below, as determined at the date of obtaining control and are amortized under the straight line method over the period indicated below: Acquisition of Navios Acquisition - Lease Future Amortization Income Within One Year Year Two Year Three Year Four Year Five Year Six and thereafter Total Time charters with favorable lease terms $ 24,398 18,232 18,156 17,702 11,182 22,469 $ 112,139 Time charters with unfavorable lease terms $ (4,672) (1,857) — — — — $ (6,529) Intangible assets and liabilities subject to amortization are amortized using straight line method over their estimated useful lives to their estimated residual value of zero. The following is a summary of the identifiable intangible asset and liability at the date of obtaining control: Acquisition of Navios Acquisition - Acquired finite lived intangible Amount Description Favorable lease terms $ 112,139 Unfavorable lease terms $ (6,529) If the acquisitions of Navios Containers and Navios Acquisition had been consummated as of January 1, 2020, Navios Partners’ pro-forma revenues and net income for the year ended December 31, 2021 would have been $ 924,978 and $ 377,071 , respectively, and for the year ended December 31, 2020 would have been $ 715,397 and $ 97,047 , respectively. These pro-forma results do not include non-recurring items directly related to the business combinations as follows: (a) the gain on remeasurement of the previously held interest on Navios Containers and the equity gain from the operations of Navios Containers upon the closing date in the amount of $ 80,839 ; (b) the total bargain gain in the amount of $ 48,015 ; and (c) the transaction costs related to the Mergers 11,169 . The pro forma results are for comparative purposes only and do not purport to be indicative of the results that would have actually been obtained if the acquisition of Navios Containers and the consolidation of Navios Acquisition had occurred at the beginning of the period presented. In addition, these results are not intended to be a projection of future results and do not reflect any synergies that might be achieved from the combined operations.

Segment Reporting [Abstract]
Segment information	NOTE 14 – SEGMENT INFORMATION Segment information ASC 280, “Segment Reporting,” establishes standards for reporting information about operating segments on a basis consistent with the Company’s internal organizational structure as well as information about geographical areas, business segments and major customers in financial statements for details on the Company’s business segments. The Company uses the “management approach” in determining reportable operating segments. The management approach considers the internal organization and reporting used by the Company’s chief operating decision maker for making operating decisions and assessing performance as the source for determining the Company’s reportable segments. 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, including the chief operating decision maker, reviews operating results solely by revenue per day and operating results of the fleet as a whole, determining where to allocate resources and drive business forward by examining consolidated results. 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, Containerships and Tankers 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 15 – 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, Cayman Islands, Liberia, British Virgin Islands and Hong Kong, 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 on the basis of the applicable licensing regime are subject to tax liability towards the Greek state, which is calculated on the basis of the relevant vessel's tonnage. A tax credit is recognized for tonnage tax (or similar tax) paid abroad, up to the amount of the tax due in Greece. The owner, the manager and the bareboat charterer or the financial lessee (where applicable) are liable to pay the tax due to the Greek state. The payment of said tax exhausts the tax liability of the foreign ship owning company, the bareboat charterer, the financial lessee (as applicable) and the relevant manager against any tax, duty, charge or contribution payable on income from the exploitation of the foreign flagged vessel outside Greece. 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.

Investment income of $ 1,133 and $ 2,532 was recognized in the Consolidated Statements of Operations under the caption of “Equity in net earnings of affiliated companies” for each of the years ended December 31, 2020 and 2019, respectively. Based on the Company's evaluation of the duration and magnitude of the fair value decline for approximately twelve months as of December 31, 2019, the Company concluded that the decline in the fair value of its investment below its carrying value was not temporary. Thus, an OTTI loss of $ 42,603 was recognized as of December 31, 2019, being the difference between the fair value of $ 25,025 and the carrying value of the investment of $ 67,628 .

Cash Distributions And Earnings Per Unit
Cash distributions and earnings per unit	NOTE 21 – CASH DISTRIBUTIONS AND EARNINGS PER UNIT Cash distributions and earnings per unit The amount of distributions paid by Navios Partners and the decision to make any distribution is determined by the Company’s board of directors and will depend on, among other things, Navios Partners’ cash requirements as measured by market opportunities and restrictions under its credit agreements and other debt obligations and such other factors as the Board of Directors may deem advisable. There is no guarantee that the Company will pay the quarterly distribution on the common units in any quarter. 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 are 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 Interest in Distributions Total Quarterly Distribution Common Incentive Distribution Right Holder 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 up to $ 6.5625 85% 13% 2% Third Target Distribution above $ 6.5625 up to $ 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. The incentive distributions rights (held by Navios GP L.L.C.) apply only after a minimum quarterly distribution of $6.0375.

Basic earnings/(losses) per common unit are 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% basis. There were no options or phantom units outstanding during each of the years ended December 31, 2021, 2020 and 2019. 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, 2021 Year Ended December 31, 2020 Year Ended December 31, 2019 Net income / (loss) attributable to Navios Partners’ unitholders $ 516,186 $ (68,541) $ (62,134) Income / (loss) attributable to: Common unitholders $ 505,862 $ (67,173) $ (60,899) Weighted average units outstanding basic Common unitholders 22,620,324 10,966,518 10,830,959 Earnings/ (losses) per unit basic: Common unitholders $ 22.36 $ (6.13) $ (5.62) Weighted average units outstanding diluted Common unitholders 22,663,240 10,966,518 10,830,959 Earnings/ (losses) per unit diluted: Common unitholders $ 22.32 $ (6.13) $ (5.62) Earnings per unit distributed basic: Common unitholders $ 0.20 $ 0.45 $ 1.22 Earnings per unit distributed diluted: Common unitholders $ 0.20 $ 0.45 $ 1.22 Earnings/ (losses per unit) - undistributed basic: Common unitholders $ 22.16 $ (6.58) $ (6.84) Earnings/ (losses) per unit undistributed diluted Common unitholders $ 22.12 $ (6.58) $ (6.84) Potential common units of 42,916 92,699 and 146,541 relating to unvested restricted common units for each of the years ended December 31, 2020 and 2019, respectively, have an anti-dilutive effect (i.e. those that increase income per unit or decrease loss per unit) and are therefore excluded from the calculation of diluted earnings per unit.

Leases
Leases	NOTE 23 – LEASES Leases Time charter out contracts and pooling arrangements The Company's contract revenues from time chartering, bareboat 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 contracts On July 24, 2019, Navios Partners took delivery of the Navios Libra , a 2019 -built Panamax vessel of 82,011 dwt, for a ten-year 6 . The Company has performed an assessment considering the lease classification criteria under ASC 842 and concluded that the arrangement is an operating lease. Consequently, the Company has recognized an operating lease liability based on the net present value of the remaining charter-in payments and a right-of-use asset at an amount equal to the operating liability adjusted for the carrying amount of the straight-line liability. On May 28, 2021 and June 10, 2021, Navios Partners took delivery of the Navios Amitie and the Navios Star , two 2021 -built Panamax vessels of 82,002 dwt and 81,994 dwt, respectively. The bareboat charter-in provides for purchase options with de-escalating purchase prices starting on the end of the fourth year and an average daily rate of $ 5.9 . The Company has performed assessments considering the lease classification criteria under ASC 842 and concluded that the arrangements are operating leases. Consequently, the Company has recognized an operating lease liability based on the net present value of the remaining charter-in payments and a right-of-use asset at an amount equal to the operating liability adjusted for the carrying amount of the straight-line liability. Upon acquisition of the majority of outstanding stock of Navios Acquisition, Navios Partners took delivery of two 12-year 2020 VLCC 313,433 2021 VLCC 313,486 21 On August 30, 2021, Navios Partners took delivery of the Nave Electron , a 2021 -built VLCC vessel of 313,329 dwt. The bareboat charter-in provides for purchase options with de-escalating purchase prices starting on the end of the fourth year and an average daily rate of $ 21 . The Company has performed assessments considering the lease classification criteria under ASC 842 and concluded that the arrangements are operating leases. The Company has recognized an operating lease liability based on the net present value of the remaining charter-in payments and a right-of-use asset at an amount equal to the operating liability adjusted for the carrying amount of the straight-line liability. Based on management estimates and market conditions, the lease term of the leases 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 applies the respective incremental borrowing rate based on the remaining lease term of the specific lease. Navios Partners’ incremental borrowing rates were approximately 7 % for Navios Libra, 5 % for Navios Amite and Navios Star, 6 % for Baghdad and Erbil and 4 % for Nave Electron. As of December 31, 2021 and December 31, 2020 the unamortized balance of the lease liability amounted $ 243,804 and $ 13,153 , respectively, and is presented under the captions “Operating lease liabilities, current portion” and “Operating lease liabilities, net” in the Consolidated Balance Sheets. Right of use assets amounted $ 244,337 and $ 13,285 as at December 31, 2021 and December 31, 2020, respectively, and are presented under the caption “Operating lease assets” in the Consolidated Balance Sheets. 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, 2021, 2020 and 2019 amounted to $ 12,757 , $ 2,086 , and $ 918 , respectively, and is included under the caption “Time charter and voyage expenses” in the Consolidated Statements of Operations. As of December 31, 2021, the management of the Company has considered various indicators, and concluded that events and circumstances did not trigger the existence of potential impairment of its operating lease assets and that step one of the impairment analysis was not required. As of December 31, 2020, 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 each of December 31, 2021, 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, 2021: Leases Charter-in vessels in operation December 31, 2022 $ 30,603 December 31, 2023 30,558 December 31, 2024 30,508 December 31, 2025 30,368 December 31, 2026 30,257 December 31, 2027 and thereafter 166,021 Total $ 318,315 Operating lease liabilities, including current portion $ 243,804 Discount based on incremental borrowing rate $ 74,511 Bareboat charter-out contract Subsequently to the charter-in agreement, the Company entered into bareboat charter-out agreements for a firm charter period of 10-years The Company recognizes in relation to the operating leases for the charter-out agreements the charter-out hire income in the consolidated statements of operations on a straight-line basis. As of December 31, 2021, the charter hire income (net of commissions, if any) amounted to $ 7,031

Summary of Significant Accounting Policies (Policies)	Dec. 31, 2021
Accounting Policies [Abstract]
Basis of presentation	(a) Basis of presentation : The accompanying consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Based on internal forecasts and projections that take into account reasonably possible changes in our trading performance, management believes that the Company has adequate financial resources to continue in operation and meet its financial commitments, including but not limited to capital expenditures, cash from sale of vessels and debt service obligations, for a period of at least twelve months from the date of issuance of these consolidated financial statements. Accordingly, the Company continues to adopt the going concern basis in preparing its financial statements. Reverse Stock Split: On April 25, 2019, the Company's unitholders approved a 1-for-15 reverse stock split of the Company's outstanding common and general partner units, which was effected on May 21, 2019. The effect of the reverse stock split was to combine 15 units of outstanding common units into one new unit, with no change in authorized units or par value per unit, and to reduce the number of common units outstanding from approximately 164.7 million units to approximately 11 .0 million units. 983 common units were issued in connection with the reverse stock split. All issued and outstanding common units contained in the financial statements, in accordance with Staff Accounting Bulletin Topic 4C, have been retroactively adjusted to reflect the reverse split for all periods presented.
Principles of consolidation	(b) Principles of consolidation : The accompanying consolidated financial statements include Navios Partners' wholly owned subsidiaries incorporated under the laws of Marshall Islands, Malta, Cayman Islands and Liberia from their dates of incorporation or from the date of acquiring control, for chartered-in vessels, from the dates charter-in agreements were in effect. All significant inter-company balances and transactions have been eliminated in Navios Partners' consolidated financial statements. Navios Partners also consolidates entities that are determined to be variable interest entities (“VIE”) as defined in the accounting guidance, if it determines that it is the primary beneficiary. A VIE is defined as a legal entity where either (i) equity interest holders as a group lack the characteristics of a controlling financial interest, including decision making ability and an interest in the entity's residual risks and rewards, (ii) the equity holders have not provided sufficient equity investment to permit the entity to finance its activities without additional subordinated financial support, or (iii) the voting rights of some investors are not proportional to their obligations to absorb the expected losses of the entity, their rights to receive the expected residual returns of the entity, or both and substantially all of the entity's activities either involve or are conducted on behalf of an investor that has disproportionately few voting rights.

Use of Estimates	(c) Use of Estimates : The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. On an on-going basis, management evaluates the estimates and judgments, including those related to uncompleted voyages, future drydock dates, the selection of useful lives for tangible assets and scrap value expected future cash flows from long-lived assets to support impairment tests, provisions necessary for accounts receivable, valuation of intangible assets and liabilities acquired in business combinations,provisions for legal disputes, and contingencies and the valuation estimates inherent in the deconsolidation gain. Management bases its estimates and judgments on historical experience and on various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from those estimates under different assumptions and/or conditions.
Cash and Cash Equivalents	(d) Cash and Cash Equivalents : Cash and cash equivalents consist of cash on hand, deposits held on call with banks, and other short-term liquid investments with original maturities of three months or less.
Restricted Cash	(e) Restricted Cash : Restricted cash, at each of December 31, 2021 and December 31, 2020, included $ 9,979 and $ 6,152 , respectively, which related to amounts held in retention accounts in order to service debt and interest payments, as required by certain of Navios Partners' credit facilities and financial liabilities. Also, as of December 31, 2020, restricted cash included $ 5,273 as cash collateral to the NIBC Credit Facility, due to the release of the Navios Soleil.
Accounts Receivable, Net	(f) Accounts Receivable, Net : Accounts receivable includes receivables from charterers for hire, freight and demurrage billings. On January 1, 2020, the Company adopted Accounting Standards Update 2016-13, “Financial Instruments - Credit Losses” (“ASC 326”). At each balance sheet date, the Company maintains an allowance for credit losses for expected uncollectible accounts receivable ( see Note 5 - Accounts Receivable, net). Navios Partners has filed claims for lost revenues in connection with the 2016 filing by Hanjin for rehabilitation, which was later followed by entry into liquidation in 2017. In October 2020, the bankruptcy court ruled against one of the two claims filed by the Company. The Company has fully provided for these amounts in its books. The allowance for credit losses was $ 2,990 as of December 31, 2021 and 2020, respectively.
Inventories	(g) Inventories : Inventories, which are comprised of: (i) bunkers (when applicable) on board of the vessels, valued at cost as determined on the first-in, first-out basis; and (ii) lubricants and stock provisions on board of the vessels as of the balance sheet date, valued at cost as determined on the first-in, first-out basis.
Vessels, Net	(h) Vessels, Net : Vessels are stated at historical cost, which consists of the contract price and pre-delivery costs incurred during the construction and delivery of newbuildings, including capitalized interest, and any material expenses incurred upon acquisition (improvements and delivery expenses) of second hand vessels. Vessels acquired in an asset acquisition or in a business combination are recorded at fair value. The fair value of the vessels is determined based on vessel valuations, from independent third party shipbrokers. Subsequent expenditures for major improvements and upgrades are capitalized, provided they appreciably extend the life, increase the earnings capacity or improve the efficiency or safety of the vessels. The cost and related accumulated depreciation of assets retired or sold are removed from the accounts at the time of sale or retirement and any gain or loss is included in the accompanying Consolidated Statements of Operations. Expenditures for routine maintenance and repairs are expensed as incurred. Depreciation is computed using the straight line method over the useful life of the vessels, after considering the estimated residual value. Management estimates the residual values of the Company’s drybulk, containerships and tankers based on a scrap value cost of steel times the weight of the ship noted in lightweight ton (“LWT”). Residual values are periodically reviewed and revised to recognize changes in conditions, new regulations or other reasons. Revisions of residual values affect the depreciable amount of the vessels and affect depreciation expense in the period of the revision and future periods. The estimated scrap rate used to calculate the vessel’s scrap value is $ 340 per LWT Management estimates the useful life of the Company’s vessels to be 25 years for drybulk and tanker vessels and 30 years from the containerships, respectively from the original construction. However, when regulations place limitations over the ability of a vessel to trade on a worldwide basis, its useful life is re-estimated to end at the date such regulations become effective. An increase in the useful life of a vessel or in its residual value would have the effect of decreasing the annual depreciation charge and extending it into later periods. A decrease in the useful life of a vessel or in its residual value would have the effect of increasing the annual depreciation charge.
Assets Held for Sale	(i) Assets Held for Sale : It is the Company's policy to dispose of vessels and other fixed assets when suitable opportunities occur and not necessarily to keep them until the end of their useful life. The Company classifies assets and disposal groups as being held for sale when the following criteria are met: management has committed to a plan to sell the vessel (disposal group); the asset (disposal group) is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of vessels; an active program to locate a buyer and other actions required to complete the plan to sell the asset (disposal group) have been initiated; the sale of the asset (disposal group) is probable and transfer of the asset (disposal group) is expected to qualify for recognition as a completed sale within one year; the asset (disposal group) is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. Long-lived assets or disposal groups classified as held for sale are measured at the lower of their carrying amount or fair value less cost to sell. These vessels are not depreciated once they meet the criteria to be held for sale. No assets were classified as held for sale as of December 31, 2021 and 2020.
Impairment of Long Lived Assets	(j) Impairment of Long Lived Assets : Vessels, other fixed assets and other long lived assets held and used by Navios Partners are reviewed periodically for potential impairment whenever events or changes in circumstances indicate that the carrying amount of a particular asset may not be fully recoverable. Navios Partners' management evaluates the carrying amounts and periods over which long-lived assets are depreciated to determine if events or changes in circumstances have occurred that would require modification to their carrying values or useful lives. Measurement of the impairment loss is based on the fair value of the asset. Navios Partners determines the fair value of its assets on the basis of management estimates and assumptions by making use of available market data and taking into consideration third party valuations performed on an individual vessel basis. In evaluating useful lives and carrying values of long-lived assets, certain indicators of potential impairment, are reviewed such as undiscounted projected operating cash flows, vessel sales and purchases, 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 vessel, the unamortized portion of deferred drydock and special survey costs, ballast water treatment system costs, exhaust gas cleaning system costs and other capitalized items, if any, 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 the 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. The management of the Company has considered various indicators, including but not limited to the market price of its long-lived assets, its contracted revenues and cash flows and the economic outlook. As of December 31, 2021, the Company concluded that events and circumstances did not trigger the existence of potential impairment of its vessels and the related intangible assets and that step one of the impairment analysis was not required. As of December 31, 2020, the Company concluded that events occurred and circumstances had changed, which indicated that potential impairment of Navios Partners' long-lived 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 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, ballast water treatment system costs, exhaust gas cleaning system costs and other capitalized items, if any, 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, vessel operating expenses as determined by the Management Agreements (as defined herein) in effect until December 2024 and thereafter assuming an increase of 3 .0% every second year and utilization rate of 98.6 % based on the fleet's historical performance. 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. During the fourth quarter of fiscal year 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 for four of its vessels, being the difference between the fair value and the vessels’ carrying value together with the carrying value of deferred drydock and special survey costs related to the vessels, presented under the caption “Vessels impairment loss” in the Consolidated Statements of Operations (see Note 7 — Vessels, net). 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 for these vessels, being the difference between the fair value and the vessels’ carrying value together with the carrying value of deferred drydock and special survey costs related to the vessels, presented under the caption “Vessels impairment loss” in the Consolidated Statements of Operations. 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 for one vessel, being the difference between the fair value and the vessel's carrying value together with the carrying value of deferred drydock and special survey costs related to the vessel, presented under the caption “Vessels impairment loss” in the Consolidated Statements of Operations (see Note 7 — Vessels, net). During the years ended December 31, 2020 and 2019, an impairment loss of $ 13,786 and $ 7,345 , respectively, was also recognized in connection with the committed sales of the Navios Soleil in December 2020, the Esperanza N in January 2021, the Castor N in February 2021 and the Navios Galaxy in April 2019, as the carrying amount of each asset group was not recoverable and exceeded its fair value less costs to sell (see Note 7 — Vessels, net). The total impairment loss recognized amounted to $ 0 , $ 71,577 and $ 36,680 for the years ended December 31, 2021, 2020 and 2019, respectively, and is presented under the caption “Vessels impairment loss” in the Consolidated Statements of Operations.
Deferred Drydock and Special Survey Costs	(k) Deferred Drydock and Special Survey Costs : Navios Partners' vessels are subject to regularly scheduled drydocking and special surveys which are generally carried out every 30 or 60 months, depending on the vessels' ages to coincide with the renewal of the related certificates issued by the classification societies, unless a further extension is obtained in rare cases and under certain conditions. The cost of drydocking and special surveys are deferred and amortized over the above periods or to the next drydocking or special survey date if such date has been determined. 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, 2021, 2020 and 2019, the amortization expense was $ 16,143 , $ 10,337 and $ 6,916 , respectively
Deferred Finance Costs	(l) Deferred Finance Costs : Deferred finance costs include fees, commissions and legal expenses associated with obtaining or modifying credit facilities and financial liabilities. Deferred finance costs are presented as a deduction from the corresponding liability. These costs are amortized over the life of the related facility using the effective interest rate method, and are presented under the caption “Interest expense and finance cost, net”. Amortization and write-off of deferred finance costs, including amortization of debt discount, for each of the years ended December 31, 2021, 2020 and 2019 were $ 3,741 , $ 2,141 and $ 10,916 , respectively.
Intangible Assets and Unfavorable Lease Terms	(m) Intangible Assets and Unfavorable Lease Terms : Navios Partners' intangible assets and liabilities consist of favorable lease terms and unfavorable lease terms. When a vessel along with the current charter contract are acquired as part of a business combination, intangible assets and unfavorable lease terms are recorded at fair value. Fair value is determined by reference to market data and the discounted amount of expected future cash flows. Where charter rates are higher than market charter rates, an asset is recorded, being the difference between the acquired charter rate and the market charter rate for an equivalent vessel. Where charter rates are less than market charter rates, a liability is recorded, being the difference between the assumed charter rate and the market charter rate for an equivalent vessel. The determination of the fair value of acquired assets and assumed liabilities requires Navios Partners to make significant assumptions and estimates of many variables including market charter rates, contracted charter rates, remaining duration of the charter agreements, the level of utilization of its vessels and its relevant discount rate. The use of different assumptions could result in a material change in the fair value of these items, which could have a material impact on Navios Partners' financial position and results of operations. 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 captions “Depreciation and amortization of intangible assets” and “Amortization of unfavorable lease terms”, respectively in the Consolidated Statements of Operations. The amortizable value of favorable leases would be considered impaired if their carrying values could not be recovered from the future undiscounted cash flows associated with the assets. As of December 31, 2021, the management of the Company has considered various indicators and concluded that events and circumstances did not trigger the existence of potential impairment of its intangible assets and that step one of the impairment analysis was not required as described in paragraph (j) above. As of December 31, 2020 and 2019, the management, after considering various indicators, performed an impairment test which included intangible assets as described in paragraph (j) above. As of December 31, 2021, 2020 and 2019 there was no impairment of intangible assets.
Foreign Currency Translation	(n) Foreign Currency Translation : Navios Partners' functional and reporting currency is the U.S. Dollar. Navios Partners engages in worldwide commerce with a variety of entities. Although, its operations may expose it to certain levels of foreign currency risk, its transactions are predominantly U.S. dollar denominated. Additionally, Navios Partners' wholly-owned vessel subsidiaries transacted a nominal amount of their operations in Euros; however, all of the subsidiaries' primary cash flows are U.S. dollar denominated. Transactions in currencies other than the functional currency are translated at the exchange rate in effect at the date of each transaction. Differences in exchange rates during the period between the date a transaction denominated in a foreign currency is consummated and the date on which it is either settled or translated, are recognized in the Statements of Operations. The foreign currency gains/ (losses) recognized in the accompanying Consolidated Statements of Operations under the captions “Other income” or “Other expense”, for each of the years ended December 31, 2021, 2020 and 2019 were not material for any of these periods.
Provisions	(o) Provisions : Navios Partners, in the ordinary course of its business, is subject to various claims, suits and complaints. Management, in consultation with internal and external advisors, will provide for a contingent loss in the financial statements if the contingency had been incurred as of the balance sheet date and the likelihood of loss was probable and the amount of the loss can be reasonably estimated. If Navios Partners has determined that the reasonable estimate of the loss is a range and there is no best estimate within the range, Navios Partners will accrue the lower amount of the range. Navios Partners, through the Management Agreements (as defined herein), 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.
Segment Reporting	(p) Segment Reporting : Navios Partners reports financial information and evaluates its operations by charter revenues and not by the length of ship employment for its customers. Navios Partners does not use discrete financial information to evaluate operating results for each type of charter or vessel type. Management does not identify expenses, profitability or other financial information by charter type. 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 (see Note 14 — Segment information).
Revenue and Expense Recognition	(q) Revenue and Expense Recognition : Revenue from time chartering Revenues from time chartering and bareboat 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. 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. 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 and bareboat chartering of vessels amounted to $ 669,185 , $ 218,809 and $ 204,920 for the years ended December 31, 2021, 2020 and 2019, respectively. Revenue from voyage contracts 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. Revenue from voyage contracts amounted to $ 25,199 , $ 3,754 and $ 9,416 for the years ended December 31, 2021, 2020 and 2019, respectively. 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 $ 17,982 , $ 4,208 and $ 5,043 for the years ended December 31, 2021, 2020 and 2019, respectively. 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 semi annual 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, 2021, 2020 and 2019 amounted to $ 809 , nil and nil, respectively. 0 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: 4.23 daily rate per Ultra-Handymax vessel; (b) $ 4.33 daily rate per Panamax vessel; (c) $ 5.25 daily rate per Capesize vessel; (d) $ 6.70 daily rate per Containership of TEU 6,800; (e) $ 7.40 daily rate per Containership of more than TEU 8,000 and (f) $ 8.75 daily rate per very large Containership of more than TEU 13,000 through December 2019. These fixed daily fees cover the vessels' operating expenses, other than certain extraordinary fees and costs In August 2019, Navios Partners extended the duration of its Management Agreement with the Manager until January 1, 2025, with an automatic renewal for an additional five years, unless earlier terminated by either party. Vessel operating expenses were fixed for two years commencing from January 1, 2020 at: (a) $ 4.35 daily rate per Ultra-Handymax Vessel; (b) $ 4.45 daily rate per Panamax Vessel; (c) $ 5.41 daily rate per Capesize Vessel; and (d) $ 6.90 daily rate per 6,800 TEU Containership. The agreement also provides for a technical and commercial management fee of $ 0.05 per day per vessel and an annual increase of 3 % after January 1, 2022 unless agreed otherwise 6.1 Following the liquidation of Navios Europe I, Navios Partners acquired three two five three two 6.1 daily rate per Sub-Panamax/Panamax Containership. The agreement also provides for a technical and commercial management fee of $ 0.05 per day per vessel and an annual increase of 3 % after January 1, 2022 for the remaining period unless agreed otherwise. Following the completion of the NMCI Merger, the fleet of Navios Containers is included in Navios Partners’ owned fleet and continued to be operated by the Manager (see Note 3 – Acquisition of Navios Containers and Navios Acquisition). As per the NMCI management agreement (the “NMCI Management Agreement”), vessel operating expenses are fixed for two years commencing from January 1, 2020 at: (a) $ 6.22 daily rate per Containership of TEU 3,000 up to 4,999, respectively; (b) $ 7.78 daily rate per Containership of TEU 8,000 up to 9,999, respectively; and (c) $ 8.27 daily rate per Containership of TEU 10,000 up to 11,999, respectively. The agreement also provides for a technical and commercial management fee of $ 0.05 per day per vessel and an annual increase of 3 % after January 1, 2022 unless agreed otherwise. Upon acquisition of the majority of outstanding stock of Navios Acquisition, the fleet of Navios Acquisition is included in Navios Partners’ owned fleet and continued to be operated by Tankers Manager (see Note 3 – Acquisition of Navios Containers and Navios Acquisition). As per the Navios Acquisition management agreement with Tankers Manager (the “NNA Management Agreement” and together with the Management Agreement and the NMCI Management Agreement, the “Management Agreements”), vessel operating expenses are fixed for two years commencing from January 1, 2020 at: (a) $ 6.8 per day per MR2 and MR1 product tanker and chemical tanker vessel; (b) $ 7.23 per day per LR1 product tanker vessel; and (c) $ 9.7 per day per VLCC. The agreement also provides for a technical and commercial management fee of $ 0.05 per day per vessel, an annual increase of 3 % after January 1, 2022 for the remaining period unless agreed otherwise. Following completion of the Mergers, the Managers provide commercial and technical management services to Navios Partners' vessels for a daily fee of: (a) $ 4.45 4.35 5.41 6.1 6.22 6.9 7.78 8.27 6.83 7.23 9.65 The Management Agreements also provide for payment of a termination fee, equal to the fees charged for the full calendar year (for Navios Partners, Navios Containers and Navios Acquisition) preceding the termination date in the event the agreements are terminated on or before December 31, 2024. Drydocking expenses are reimbursed at cost for all vessels. During the years ended December 31, 2021 and 2020 certain extraordinary fees and costs related to vessels’ regulatory requirements, including ballast water treatment system installation and exhaust gas cleaning system installation under the Company's Management Agreements, amounted to $ 11,408 and $ 3,366 , respectively, and are presented under the caption “Acquisition of/ additions to vessels, net of cash acquired” in the Consolidated Statements of Cash Flows. During year ended December 31, 2021, certain extraordinary fees and costs related to Covid-19 measures, including crew related expenses, amounted to $ 5,811 2,034 Vessel operating expenses for each of the years ended December 31, 2021, 2020 and 2019 amounted to $ 191,449 , $ 93,732 and $ 68,188 , respectively. General and administrative expenses: Total general and administrative expenses charged by the Managers for each of the years ended December 31, 2021, 2020 and 2019 amounted to $ 28,805 , $ 13,708 and $ 10,406 , respectively.
Financial Instruments	(r) Financial Instruments : Financial instruments carried on the balance sheet include cash and cash equivalents, restricted cash, trade receivables and payables, other receivables and other liabilities, long-term debt and financial liabilities. The particular recognition methods applicable to each class of financial instrument are disclosed in the applicable significant policy description of each item, or included below as applicable. 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, 2021, Singapore Marine Pte. Ltd (“Singapore Marine”) represented approximately 14.5 % of our total revenues. For the year ended December 31, 2020 HMM, Singapore Marine and Cargill represented approximately 23.4 %, 19.5 % and 11.4 %, respectively, of the Company’s total revenues. For the year ended December 31, 2019 HMM, Swissmarine and Cargill represented approximately 25.9 %, 12.3 % and 10.9 %, respectively, of the Company’s total revenues. No other customers accounted for 10% or more of total revenues for any of the years presented. 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 (as defined herein) 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 $ 4,615 , $ 7,872 and $ 13,550 to its unitholders of common and general partner units during the years ended December 31, 2021, 2020 and 2019, respectively. Maintenance and Replacement Capital Expenditures 83,147 , $ 36,455 and $ 29,039 , respectively.
Stock-based compensation	(t) Stock-based compensation : In February 2019, December 2019, December 2018 and December 2017, Navios Partners granted restricted common units to its directors and officers, which are based solely on service conditions and vest over four years each, respectively. Following the NNA Merger, Navios Partners assumed the restricted common units granted in December 2018 and December 2017 to directors and officers of Navios Acquisition, which are based solely on service conditions and vest over four years each, respectively. Upon the NNA Merger, the unvested restricted common units were 11,843 after exchange on a 1 to 0.1275 basis. The fair value of restricted common units is determined by reference to the quoted stock price on the date of grant or the date that the grants were exchanged upon completion of the NNA Merger. Compensation expense, net of estimated forfeitures, is recognized based on a graded expense model over the vesting period. The effect of compensation expense arising from the restricted common units described above amounted to $ 523 , $ 946 and $ 2,018 for the years ended December 31, 2021, 2020 and 2019, respectively, and was presented under the caption “General and administrative expenses” in the Consolidated Statements of Operations. There were no restricted common units exercised, forfeited or expired during the years ended December 31, 2021, 2020 and 2019. As of December 31, 2021, 347,389 restricted common units were vested, cumulatively.
Income Taxes	(u) Income Taxes : The Company is a Marshall Islands Corporation. Pursuant to various treaties and the United States Internal Revenue Code, the Company believes that substantially all its operations are exempt from income taxes in the Marshall Islands and the United States of America. Under the laws of Marshall Islands, Malta, Cayman Islands, Liberia, British Virgin Islands and Hong Kong, 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.
(Loss)/Earnings Per Unit	(v) (Loss)/Earnings Per Unit : Basic (losses)/earnings per unit is computed by dividing net (loss)/income attributable to Navios Partners common unitholders by the weighted average number of common units outstanding during the periods presented. Diluted earnings per unit reflect the potential dilution that would occur if securities or other contracts to issue common units were exercised or converted. 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.
Guarantees	(w) Guarantees : An asset for the fair value of a right undertaken in issuing the guarantee is recognized. The recognition of fair value is not required for certain guarantees such as the parent's guarantee of a subsidiary's debt to a third party or guarantees on product warranties. For those guarantees excluded from the above guidance requiring the fair value recognition of the asset, financial statement disclosures of their terms are made. 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 . In October 2020, Navios Holdings paid an amount of $ 5,000 5,000 to Navios Partners. As of December 31, 2021 and 2020, the outstanding claim receivable amounted to $ 0 and $ 5,000 , respectively.
Leases	(x) Leases : Vessel leases where Navios Partners is regarded as the lessor are classified as either operating leases or sales type/ direct financing leases, based on an assessment of the terms of the lease. 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. After lease commencement, the Company measures the lease liability for an operating lease at the present value of the remaining lease payments using the discount rate determined at lease commencement. The right-of-use asset is subsequently measured at the amount of the remeasured lease liability, adjusted for the remaining balance of any lease incentives received, any cumulative prepaid or accrued rent if the lease payments are uneven throughout the lease term and any unamortized initial direct costs. Any changes made to leased assets to customize it for a particular use or need of the lessee are capitalized as leasehold improvements. Amounts attributable to leasehold improvements are presented separately from the related right-of-use asset. In cases of Navios Acquisition’s lease agreements at the date of obtaining control, the Company measured the lease liability at the present value of the remaining lease payments as if these lease agreements were a new lease of the Company at the date of obtaining control. 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. The expense is included under 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 weighted average cost-of capital (“WACC”). As of December 31, 2021, the management of the Company has considered various indicators, and concluded that events and circumstances did not trigger the existence of potential impairment of its operating lease assets and that step one of the impairment analysis was not required. As of December 31, 2020, the 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), vessel operating expenses in accordance with the terms of Management Agreements (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 : Guidance on Fair Value Measurements provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level I measurements) and the lowest priority to unobservable inputs (Level III measurements). 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 July 2021, the FASB issued ASU 2021-05, Lease (Topic 842): Lessors—Certain Leases with Variable Lease Payments (“ASU 2021-05”). The guidance in ASU 2021-05 amends the lease classification requirements for the lessors under certain leases containing variable payments to align with practice under ASC 840. The lessor should classify and account for a lease with variable lease payments that do not depend on a reference index or a rate as an operating lease if both of the following criteria are met: 1) the lease would have been classified as a sales-type lease or a direct financing lease in accordance with the classification criteria in ASC 842-10-25-2 through 25-3; and 2) the lessor would have otherwise recognized a day-one loss. The amendments in ASU 2021-05 are effective for fiscal years beginning after December 15, 2021, with early adoption permitted. The Company is currently evaluating the impact of adoption to the consolidated and combined financial statements and related disclosures.

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.
