Summary of Significant Accounting Policies	NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Summary of Significant Accounting Policies (a) Basis of presentation: (b) Principles of consolidation: 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.

Investments in Affiliates: 6,900 Affiliates included in the financial statements accounted for under the equity method: 33.5 100 5.0 Revenue and Expense Recognition: The Company’s contract revenues from time chartering and pooling arrangements are governed by ASU 2016-02 (ASC 842) “Leases”. Upon adoption of ASC 606 and ASC 842, the timing and recognition of earnings from the pool arrangements and time charter contracts to which the Company is party did not change from previous practice. The Company has determined to recognize lease revenue as a combined single lease component for all time charters (operating leases) as the related lease component and non-lease components will have the same timing and pattern of the revenue recognition of the combined single lease component. The performance obligations in a time charter contract are satisfied over term of the contract beginning when the vessel is delivered to the charterer until it is redelivered back to the Company. Revenue from time chartering Revenues from time chartering of vessels are accounted for as operating leases and are thus recognized on a straight line basis as the average lease revenue over the rental periods of such charter agreements, as service is performed. A time charter involves placing a Revenue from time chartering of vessels 145,241 and $ 45,679 for the three month periods ended June 30, 2021 and 2020, respectively. Revenue from time chartering of vessels amounted to $ 207,740 and $ 91,328 for the six month periods ended June 30, 2021 and 2020, respectively. Revenue from voyage contracts Under a voyage charter, a vessel is provided for the transportation 4,389 306 5,609 306 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 2,379 564 3,723 1,405 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. There was no 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.

As a result, there was no impairment for the three and six month period ended June 30, 2021. 2020 As of June 30, 2020, we concluded that events and circumstances triggered the existence of potential impairment of our vessels. These indicators included volatility in the charter market as well as the potential impact the current marketplace may have on our future operations. As a result, we performed step one of the impairment assessment of our vessels by comparing the undiscounted projected net operating cash flows for each vessel to its carrying value. As of June 30, 2020, our 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, we recorded an impairment loss of $ 6,800

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

Income Tax Disclosure [Abstract]
Income taxes	NOTE 11 – INCOME TAXES Income taxes Marshall Islands, Malta and Liberia do not impose a tax on international shipping income. Under the laws of Marshall Islands, Malta and Liberia, the countries of the vessel-owning subsidiaries’ incorporation and vessels’ registration, the vessel-owning subsidiaries are subject to registration and tonnage taxes, which have been included in vessel operating expenses in the accompanying condensed Consolidated Statements of Operations. In accordance with the currently applicable Greek law, foreign flagged vessels that are managed by Greek or foreign ship management companies having established an office in Greece are subject to duties towards the Greek state, which are calculated on the basis of the relevant vessel’s tonnage. The payment of said duties exhausts the tax liability of the foreign ship owning company and the relevant manager against any tax, duty, charge or contribution payable on income from the exploitation of the foreign flagged vessel. Pursuant to Section 883 of the Internal Revenue Code of the United States, U.S. source income from the international operation of ships is generally exempt from U.S. income tax if the company operating the ships meets certain incorporation and ownership requirements. Among other things, in order to qualify for this exemption, the company operating the ships must be incorporated in a country, which grants an equivalent exemption from income taxes to U.S. corporations. All the vessel-owning subsidiaries satisfy these initial criterias. 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.

Diluted earnings per unit is calculated in the same manner as basic earnings per unit, except that the weighted average number of outstanding units increased to include the dilutive effect of outstanding unit options or phantom units. Net loss per unit undistributed is determined by taking the distributions in excess of net income and allocating between common units and general partner units on a 98% 2% The calculations of the basic and diluted earnings per unit are presented below.

Leases	NOTE 17 – LEASES Leases Time charter out contracts and pooling arrangements The Company’s contract revenues from time chartering and pooling arrangements are governed by ASC 842. Upon adoption of ASC 842, the timing and recognition of earnings from the time charter contracts and pool arrangements to which the Company is party did not change from previous practice. For further analysis, (see Note 2— Summary of Significant Accounting Policies). Bareboat charter-in contract On July 24, 2019, Navios Partners took delivery of the Navios Libra 2019 Panamax 82,011 ten year 6 On May 28, 2021 and June 10, 2021, Navios Partners took delivery of the Navios Amitie Navios Star 2021 Panamax 82,002 81,994 5.9 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 applied the respective incremental borrowing rate based on the remaining lease term of the specific lease. Navios Partners’ incremental borrowing rates were approximately 7% 5% As of June 30, 2021 and December 31, 2020 the balance of the lease liability amounted $ 45,669 13,153 45,862 13,285 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 three and six month periods ended June 30, 2021 amounted to $ 841 1,354 519 1,037 The table below provides the total amount of lease payments on an undiscounted basis on the Company’s chartered-in contracts as of June 30, 2021: Leases Amount 2022 6,668 2023 6,583 2024 6,592 2025 6,388 2026 and thereafter 33,172 Total $ 59,403 Operating lease liabilities, including current portion $ 45,669 Discount based on incremental borrowing rate $ 13,734 Sale and Lease Back Agreements During the years from 2018 to 2021, the Company has entered into sale and leaseback agreements with unrelated third parties for various vessels of the Company’s fleet. Navios Partners has purchase obligations to acquire the vessels at the end of the lease terms, consequently under ASC 842-40 the transfers of the vessels were determined to be failed sales and were treated as financing transactions. The vessels were not derecognized and continue to be depreciated over their respective useful lives, and tested for impairment as per Company’s policy (see Note 7- Borrowings).

Revenue and Expense Recognition:	Revenue and Expense Recognition: The Company’s contract revenues from time chartering and pooling arrangements are governed by ASU 2016-02 (ASC 842) “Leases”. Upon adoption of ASC 606 and ASC 842, the timing and recognition of earnings from the pool arrangements and time charter contracts to which the Company is party did not change from previous practice. The Company has determined to recognize lease revenue as a combined single lease component for all time charters (operating leases) as the related lease component and non-lease components will have the same timing and pattern of the revenue recognition of the combined single lease component. The performance obligations in a time charter contract are satisfied over term of the contract beginning when the vessel is delivered to the charterer until it is redelivered back to the Company.
