DESCRIPTION OF BUSINESS [Abstract]
Description of Business	NOTE 1 – DESCRIPTION OF BUSINESS Navios Maritime Partners L.P. (“Navios Partners” or the “Company”), is an international owner and operator of dry cargo vessels, formed on August 7, 2007 under the laws of the Republic of the Marshall Islands. Navios GP L.L.C. (the “General Partner”), a wholly owned subsidiary of Navios Maritime Holdings Inc. (“Navios Holdings”), was also formed on that date to act as the general partner of Navios Partners and received a 2.0% general partner interest in Navios Partners. Navios Partners is engaged in the seaborne transportation services of a wide range of dry cargo commodities including iron ore, coal, grain, fertilizer and also containers, chartering its vessels under medium to longer-term charters. The operations of Navios Partners are managed by Navios Shipmanagement Inc., a subsidiary of Navios Holdings (the “Manager”), from its offices in Piraeus, Greece, Singapore and Monaco. Pursuant to the initial public offering (“IPO”) on November 16, 2007, Navios Partners entered into the following agreements: (a) a management agreement with the Manager (the “Management Agreement”), pursuant to which the Manager provides Navios Partners commercial and technical management services; (b) an administrative services agreement with the Manager (the “Administrative Services Agreement”), pursuant to which the Manager provides Navios Partners administrative services; and (c) an omnibus agreement with Navios Holdings (the “Omnibus Agreement”), governing, among other things, when Navios Partners and Navios Holdings may compete against each other as well as rights of first offer on certain drybulk carriers. As of June 30, 2019, there were outstanding: 10,983,785 common units and 230,524 general partnership units. As of June 30, 2019, Navios Holdings owned a 20.5% interest in Navios Partners, which included a 2.1% general partner interest.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]
Summary of Significant Accounting Policies	NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of presentation : The accompanying interim condensed consolidated financial statements are unaudited, but, in the opinion of management, reflect all adjustments for a fair statement of Navios Partners’ consolidated balance sheets, statement of partner’s capital, statements of operations and cash flows for the periods presented. The results of operations for the interim periods are not necessarily indicative of results for the full year. The footnotes are condensed as permitted by the requirements for interim financial statements and accordingly, do not include information and disclosures required under United States generally accepted accounting principles (“U.S. GAAP”) for complete financial statements. All such adjustments are deemed to be of a normal recurring nature. These interim financial statements should be read in conjunction with the Company’s consolidated financial statements and notes included in Navios Partners’ Annual Report for the year ended December 31, 2018 filed on Form 20-F with the U.S. Securities and Exchange Commission (“SEC”). Reverse Stock Split: On April 25, 2019, the unitholders of Navios Partners approved a 1-for-15 reverse stock split of all outstanding common and general partner units of the Company which was effected on May 21, 2019. The effect of the reverse stock split was to combine each 15 units of outstanding units into one new unit, and to reduce the number of common units outstanding from approximately 164.7 million units to approximately 11.0 million units. 1,058 common units were issued in connection with the reverse stock split. All issued and outstanding common and general partner 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: The accompanying interim condensed consolidated financial statements include Navios Partners’ wholly owned subsidiaries incorporated under the laws of Marshall Islands, Malta, and Liberia from their dates of incorporation or, 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. 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 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. Subsidiaries: Subsidiaries are those entities in which Navios Partners has an interest of more than one half of the voting rights or otherwise has power to govern the financial and operating policies of the entity.

(8) The vessel was sold on April 23, 2019 (see Note 4 – Vessels, net). (9) The vessel was delivered on July 24, 2019 (see Note 18 – Subsequent Events). Revenue and Expense Recognition : On January 1, 2018, the Company adopted the provisions of ASC 606 “Revenue from Contracts with Customers”. The guidance provides a unified model to determine how revenue is recognized. In doing so, the Company makes judgments including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price, and allocating the transaction price to each performance obligation. Revenue is recognized when (or as) the Company transfers promised goods or services to its customers in amounts that reflect the consideration to which the company expects to be entitled to in exchange for those goods or services, which occurs when (or as) the Company satisfies its contractual obligations and transfers control of the promised goods or services to its customers. Revenues are recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In determining the appropriate amount of revenue to be recognized as it fulfills its obligations under its agreements, the Company performs the following steps: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations, including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations based on estimated selling prices; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation. 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 component will have the same timing and pattern of the revenue recognition of the combined single lease component. The performance obligations in a time charter contract are satisfied over term of the contract beginning when the vessel is delivered to the charterer until it is redelivered back to the Company. As a result of the adoption of these standards, there was no effect on the Company’s opening retained earnings, Balance Sheets and Statements of Operations. The Company’s revenues earned under voyage contracts (revenues for the transportation of cargo) were previously recognized ratably over the estimated relative transit time of each voyage. A voyage was deemed to commence when a vessel was available for loading and was deemed to end upon the completion of the discharge of the current cargo. Estimated losses on voyages are provided for in full at the time such losses become evident. Under a voyage charter, a vessel is provided for the transportation of specific goods between specific ports in return for payment of an agreed upon freight per ton of cargo. Following the 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 $3,808 and $3,814 for the six month periods ended June 30, 2019 and 2018, respectively. 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. Revenues from time chartering of vessels are accounted for as operating leases and are thus recognized on a straight line basis as the average lease revenue over the rental periods of such charter agreements, as service is performed. A time charter involves placing a vessel at the charterers’ disposal for a period of time during which the charterer uses the vessel in return for the payment of a specified daily hire rate. Short period charters for less than three months are referred to as spot-charters. Charters extending three months to a year are generally referred to as medium-term charters. All other charters are considered long-term. Under time charters, operating costs such as for crews, maintenance and insurance are typically paid by the owner of the vessel. Revenue from time chartering of vessels amounted to $88,979 and $104,672 for the six month periods ended June 30, 2019 and 2018, respectively. Profit-sharing revenues are calculated at an agreed percentage of the excess of the charterer’s average daily income (calculated on a quarterly or half-yearly basis) over an agreed amount and accounted for on an accrual basis based on provisional amounts and for those contracts that provisional accruals cannot be made due to the nature of the profit sharing elements, these are accounted for on the actual cash settlement or when such revenue becomes determinable. 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 and profit sharing arrangements amounted to $1,776 and $2,762 for the six month periods ended June 30, 2019 and 2018, respectively. Recent Accounting Pronouncements: In October 2018, the Financial Accounting Standards Board (“FASB”) issued ASU 2018-17, Consolidation (Topic 810): “Targeted Improvements to Related Party Guidance for Variable Interest Entities” (“ASU 2018-17”). ASU 2018-17 provides that indirect interests held through related parties in common control arrangements should be considered on a proportional basis for determining whether fees paid to decision makers and service providers are variable interests. This is consistent with how indirect interests held through related parties under common control are considered for determining whether a reporting entity must consolidate a VIE. For public business entities the amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently assessing the impact that adopting this new accounting guidance will have on its disclosures to the consolidated financial statements. In August 2018, FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement”. This update modifies the disclosure requirements on fair value measurements. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, and earlier adoption is permitted. The Company is currently assessing the impact that adopting this new accounting guidance will have on its disclosures to the consolidated financial statements. In June 2016, FASB issued ASU No. 2016-13, “Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” This standard requires entities to measure all expected credit losses of financial assets held at a reporting date based on historical experience, current conditions, and reasonable and supportable forecasts in order to record credit losses in a more timely manner. ASU 2016-13 also amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The standard is effective for interim and annual reporting periods beginning after December 15, 2019, although early adoption is permitted for interim and annual periods beginning after December 15, 2018. In November 2018, FASB issued ASU 2018-19“Codification Improvements to topic 326, Financial Instruments-Credit Losses”. The amendments in this update clarify that operating lease receivables are not within the scope of ASC 326-20 and should instead be accounted for under the new leasing standard, ASC 842. In April 2019, FASB issued ASU 2019-04 “Codification Improvements to topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments”. In May 2019, FASB issued ASU 2019-05, “Financial Instruments-Credit Losses (Topic 326): Targeted Transition Relief”. The amendments in this update provide entities that have certain instruments within the scope of Subtopic 326-20, Financial Instruments-Credit Losses-Measured at Amortized Cost, with an option to irrevocably elect the fair value option in Subtopic 825-10, Financial Instruments-Overall, applied on an instrument-by-instrument basis for eligible instruments, upon adoption of Topic 326. The fair value option election does not apply to held-to-maturity debt securities. An entity that elects the fair value option should subsequently apply the guidance in Subtopics 820-10, Fair Value Measurement-Overall, and 825-10. The Company is currently assessing the impact that adopting this new accounting guidance will have on its consolidated financial statements.

The facility matures in the fourth quarter of 2023 and bears interest at LIBOR plus 275 bps over annum. DNB Credit Facility: On April 5, 2019, Navios Partners entered into a new credit facility with DNB Bank ASA (the “April 2019 Credit Facility”) of up to $40,000 (divided into two tranches) in order to refinance two Capesize vessels, previously included in the Term Loan B collateral package. The credit facility has a term of approximately five years and bears interest at LIBOR plus 275 bps per annum. As of June 30, 2019, no amount had been drawn under this facility.

FAIR VALUE OF FINANCIAL INSTRUMENTS [ABSTRACT]
Fair Value of Financial Instruments	NOTE 7 – FAIR VALUE OF FINANCIAL INSTRUMENTS The carrying value amounts of many of Navios Partners’ financial instruments, including cash and cash equivalents, restricted cash, accounts receivable and accounts payable and amounts due to related parties approximate their fair value due primarily to the short-term maturity of the related instruments. The following methods and assumptions were used to estimate the fair value of each class of financial instrument: Cash and cash equivalents: The carrying amounts reported in the condensed Consolidated Balance Sheets for interest bearing deposits approximate their fair value because of the short maturity of these investments. Restricted Cash: The carrying amounts reported in the condensed Consolidated Balance Sheets for interest bearing deposits approximate their fair value because of the short maturity of these investments. Amounts due from related parties, short-term: The carrying amount of due from related parties, short-term reported in the balance sheet approximates its fair value due to the short-term nature of these receivables. Loans receivable from affiliates: The carrying amount of the fixed rate loan approximates its fair value. Amounts due from related parties, long-term: The carrying amount of due from related parties long-term reported in the balance sheet approximates its fair value due to the long-term nature of these receivables. Notes receivable, net of current portion: The carrying amount of the fixed rate notes receivable approximate its fair value. Note receivable from affiliates: The carrying amount of the long-term receivable from affiliates approximates its fair value. Term Loan B Facility: The fair value of the Company’s debt is estimated based on currently available debt with similar contract terms, interest rate and remaining maturities, as well as taking into account our creditworthiness. The book value has been adjusted to reflect the net presentation of deferred finance fees. Other long-term borrowings, net: The book value has been adjusted to reflect the net presentation of deferred finance fees. The outstanding balance of the floating rate loans continues to approximate its fair value, excluding the effect of any deferred finance fees. The estimated fair values of the Navios Partners’ financial instruments are as follows: June 30, 2019 December 31, 2018 Book Value Fair Value Book Value Fair Value Cash and cash equivalents $33,884 $33,884 $58,590 $58,590 Restricted cash $1,336 $1,336 $2,865 $2,865 Amounts due from related parties, short-term $17,936 $17,936 $28,562 $28,562 Loans receivable from affiliates $31,840 $31,840 $27,657 $27,657 Amounts due from related parties, long-term $38,086 $38,086 $28,880 $28,880 Notes receivable, net of current portion $9,673 $9,673 $11,629 $11,629 Note receivable from affiliates $4,666 $4,666 $4,525 $4,525 Term Loan B Facility, net $(333,718) $(338,902) $(408,662) $(414,352) Other long-term borrowings, net $(151,345) $(153,756) $(98,823) $(100,513) Fair Value Measurements The estimated fair value of our financial instruments that are not measured at fair value on a recurring basis, categorized based upon the fair value hierarchy, are as follows: Level I: Inputs are unadjusted, quoted prices for identical assets or liabilities in active markets that we have the ability to access.

Issuance of Units	NOTE 8 – ISSUANCE OF UNITS On April 25, 2019, Navios Partners announced that its Board of Directors has approved 1-for-15 reverse stock split of its issued and outstanding shares of common units and general partners units. The reverse stock split was effective on May 21, 2019 and the common units commenced trading on such date on a split adjusted basis. In February 2019, Navios Partners authorized the granting of 25,396 restricted common units, which were issued on February 1, 2019, to its directors and officers, which are based solely on service conditions and vest over four years. The fair value of restricted common units was determined by reference to the quoted stock price on the date of grant. Compensation expense, net of estimated forfeitures, is recognized based on a graded expense model over the vesting period. Navios Partners also issued 518 general partnership units to its general partner for net proceeds of $8. The effect of compensation expense arising from the restricted common units described above amounted to $52 and $85 for the three and six month period ended June 30, 2019 and was presented under the caption “General and administrative expenses” in the condensed Consolidated Statements of Operations. In January 2019, the Board of Directors of Navios Partners authorized a common unit repurchase program for up to $50,000 of the Company’s common units over a two year period. The program does not require any minimum repurchase or any specific number of common units and may be suspended or reinstated at any time in Navios Partners’ discretion and without notice. The Board of Directors will review the program periodically. Repurchases are subject to restrictions under Navios Partners’ credit facilities. As of June 30, 2019, Navios Partners had repurchased and cancelled 312,952 common units on a split adjusted basis, for a total cost of approximately $4,499.

SEGMENT INFORMATION [Abstract]
Segment Information	NOTE 9 – 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 TAXES [Abstract]
Income Taxes	NOTE 10 – 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 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.

Provisions have been recognized in the financial statements for all such proceedings where Navios Partners believes that a liability may be probable, and for which the amounts are reasonably estimable, based upon facts known at the date the financial statements were prepared. Management believes the ultimate disposition of these matters will be immaterial individually and in the aggregate to Navios Partners’ financial position, results of operations or liquidity. In November 2017, Navios Partners agreed to charter-in, under a ten-year bareboat contract, from an unrelated third party, a newbuilding Panamax vessel of approximately 82,011 dwt, delivered on July 24, 2019.

There is no guarantee that Navios Partners will pay a quarterly distribution on the common and general partner units in any quarter. On February 3, 2016, Navios Partners announced that its Board of Directors decided to suspend the quarterly cash distributions to its unitholders, including the distribution for the quarter ended December 31, 2015. In March 2018, the board determined to reinstate a distribution and any continued distribution will be at the discretion of our Board of Directors, taking into consideration the terms of its partnership agreement. The Company is prohibited from making any distributions to unitholders if it would cause an event of default, or an event of default exists, under its existing credit facilities. There is incentive distribution rights held by the General Partner, which are analyzed as follows: Marginal Percentage Interest in Distributions Total Quarterly Distribution Target Amount Common Unitholders General Partner 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% 15% Third Target Distribution above $6.5625 up to $7.875 75% 25% Thereafter above $7.875 50% 50% The first 98% of the quarterly distribution is paid to all common unitholders. The incentive distributions rights (held by the General Partner) apply only after a minimum quarterly distribution of $6.0375. In April 2018, the Board of Directors of Navios Partners authorized its quarterly cash distribution for the three month period ended March 31, 2018 of $0.30 per unit. The distribution was paid on May 14, 2018 to all unitholders of common and general partner units of record as of May 10, 2018. The aggregate amount of the declared distribution was $3,420. In July 2018, the Board of Directors of Navios Partners authorized its quarterly cash distribution for the three month period ended June 30, 2018 of $0.30 per unit. The distribution was paid on August 10, 2018 to all unitholders of common and general partner units of record as of August 7, 2018. The aggregate amount of the declared distribution was $3,420. In October 2018, the Board of Directors of Navios Partners authorized its quarterly cash distribution for the three month period ended September 30, 2018 of $0.30 per unit. The distribution was paid on November 14, 2018 to all unitholders of common and general partners units of record as of November 7, 2018. The aggregate amount of the declared distribution was $3,420. In January 2019, the Board of Directors of Navios Partners authorized its quarterly cash distribution for the three month period ended December 31, 2018 of $0.30 per unit. The distribution was paid on February 14, 2019 to all unitholders of common and general partner units of record as of February 11, 2019, which included the unitholders of restricted common units issued on February 1, 2019.

The distribution is payable on August 9, 2019 to all unitholders of common and general partner units of record as of August 6, 2019. The aggregate amount of the declared distribution will be $3,364. Navios Partners calculates earnings per unit by allocating reported net income for each period to each class of units based on the distribution waterfall for available cash specified in Navios Partners’ partnership agreement, net of the unallocated earnings (or losses). Basic earnings/(losses) per unit is determined by dividing net income/(loss) attributable to Navios Partners common unitholders by the weighted average number of common units outstanding during the period. Diluted earnings per unit is calculated in the same manner as basic earnings per unit, except that the weighted average number of outstanding units increased to include the dilutive effect of outstanding unit options or phantom units. Net loss per unit undistributed is determined by taking the distributions in excess of net income and allocating between common units and general partner units on a 98%-2% basis. There were no options or phantom units outstanding during each of the six month periods ended June 30, 2019 and 2018. The calculations of the basic and diluted earnings per unit are presented below. Three Month Period Ended Six Month Period Ended June 30, 2019 June 30, 2018 June 30, 2019 June 30, 2018 Net loss $(6,523) $(29,533) $(16,046) $(24,055) Loss attributable to: Common unit holders (6,394) (28,942) (15,729) (23,574) Weighted average units outstanding (basic and diluted) Common unit holders 10,774,452 10,991,092 10,898,658 10,645,044 Loss per unit (basic and diluted): Common unit holders $(0.59) $(2.64) $(1.44) $(2.21) Earnings per unit — distributed (basic and diluted): Common unit holders $0.30 $0.30 $0.60 $0.63 Loss per unit — undistributed (basic and diluted): Common unit holders $(0.89) $(2.94) $(2.04) $(2.84) Potential common units of 235,669 and 90,222 relating to unvested restricted common units for each of the three and six month periods ended June 30, 2019 and 2018, 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.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Jun. 30, 2019
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]
Basis Of Presentation	Basis of presentation : The accompanying interim condensed consolidated financial statements are unaudited, but, in the opinion of management, reflect all adjustments for a fair statement of Navios Partners’ consolidated balance sheets, statement of partner’s capital, statements of operations and cash flows for the periods presented. The results of operations for the interim periods are not necessarily indicative of results for the full year. The footnotes are condensed as permitted by the requirements for interim financial statements and accordingly, do not include information and disclosures required under United States generally accepted accounting principles (“U.S. GAAP”) for complete financial statements. All such adjustments are deemed to be of a normal recurring nature. These interim financial statements should be read in conjunction with the Company’s consolidated financial statements and notes included in Navios Partners’ Annual Report for the year ended December 31, 2018 filed on Form 20-F with the U.S. Securities and Exchange Commission (“SEC”). Reverse Stock Split: On April 25, 2019, the unitholders of Navios Partners approved a 1-for-15 reverse stock split of all outstanding common and general partner units of the Company which was effected on May 21, 2019. The effect of the reverse stock split was to combine each 15 units of outstanding units into one new unit, and to reduce the number of common units outstanding from approximately 164.7 million units to approximately 11.0 million units. 1,058 common units were issued in connection with the reverse stock split. All issued and outstanding common and general partner 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.
Subsidiaries	Principles of consolidation: The accompanying interim condensed consolidated financial statements include Navios Partners’ wholly owned subsidiaries incorporated under the laws of Marshall Islands, Malta, and Liberia from their dates of incorporation or, 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. 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 and debt service obligations, for a period of at least twelve months from the date of issuance of these consolidated financial statements.

Revenue and Expense Recognition	Revenue and Expense Recognition : On January 1, 2018, the Company adopted the provisions of ASC 606 “Revenue from Contracts with Customers”. The guidance provides a unified model to determine how revenue is recognized. In doing so, the Company makes judgments including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price, and allocating the transaction price to each performance obligation. Revenue is recognized when (or as) the Company transfers promised goods or services to its customers in amounts that reflect the consideration to which the company expects to be entitled to in exchange for those goods or services, which occurs when (or as) the Company satisfies its contractual obligations and transfers control of the promised goods or services to its customers. Revenues are recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In determining the appropriate amount of revenue to be recognized as it fulfills its obligations under its agreements, the Company performs the following steps: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations, including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations based on estimated selling prices; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation. 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 component will have the same timing and pattern of the revenue recognition of the combined single lease component. The performance obligations in a time charter contract are satisfied over term of the contract beginning when the vessel is delivered to the charterer until it is redelivered back to the Company. As a result of the adoption of these standards, there was no effect on the Company’s opening retained earnings, Balance Sheets and Statements of Operations. The Company’s revenues earned under voyage contracts (revenues for the transportation of cargo) were previously recognized ratably over the estimated relative transit time of each voyage. A voyage was deemed to commence when a vessel was available for loading and was deemed to end upon the completion of the discharge of the current cargo. Estimated losses on voyages are provided for in full at the time such losses become evident. Under a voyage charter, a vessel is provided for the transportation of specific goods between specific ports in return for payment of an agreed upon freight per ton of cargo. Following the 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 $3,808 and $3,814 for the six month periods ended June 30, 2019 and 2018, respectively. 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. Revenues from time chartering of vessels are accounted for as operating leases and are thus recognized on a straight line basis as the average lease revenue over the rental periods of such charter agreements, as service is performed. A time charter involves placing a vessel at the charterers’ disposal for a period of time during which the charterer uses the vessel in return for the payment of a specified daily hire rate. Short period charters for less than three months are referred to as spot-charters. Charters extending three months to a year are generally referred to as medium-term charters. All other charters are considered long-term. Under time charters, operating costs such as for crews, maintenance and insurance are typically paid by the owner of the vessel. Revenue from time chartering of vessels amounted to $88,979 and $104,672 for the six month periods ended June 30, 2019 and 2018, respectively. Profit-sharing revenues are calculated at an agreed percentage of the excess of the charterer’s average daily income (calculated on a quarterly or half-yearly basis) over an agreed amount and accounted for on an accrual basis based on provisional amounts and for those contracts that provisional accruals cannot be made due to the nature of the profit sharing elements, these are accounted for on the actual cash settlement or when such revenue becomes determinable. 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 and profit sharing arrangements amounted to $1,776 and $2,762 for the six month periods ended June 30, 2019 and 2018, respectively.
Recent Accounting Pronouncements	Recent Accounting Pronouncements: In October 2018, the Financial Accounting Standards Board (“FASB”) issued ASU 2018-17, Consolidation (Topic 810): “Targeted Improvements to Related Party Guidance for Variable Interest Entities” (“ASU 2018-17”). ASU 2018-17 provides that indirect interests held through related parties in common control arrangements should be considered on a proportional basis for determining whether fees paid to decision makers and service providers are variable interests. This is consistent with how indirect interests held through related parties under common control are considered for determining whether a reporting entity must consolidate a VIE. For public business entities the amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently assessing the impact that adopting this new accounting guidance will have on its disclosures to the consolidated financial statements. In August 2018, FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement”. This update modifies the disclosure requirements on fair value measurements. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, and earlier adoption is permitted. The Company is currently assessing the impact that adopting this new accounting guidance will have on its disclosures to the consolidated financial statements. In June 2016, FASB issued ASU No. 2016-13, “Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” This standard requires entities to measure all expected credit losses of financial assets held at a reporting date based on historical experience, current conditions, and reasonable and supportable forecasts in order to record credit losses in a more timely manner. ASU 2016-13 also amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The standard is effective for interim and annual reporting periods beginning after December 15, 2019, although early adoption is permitted for interim and annual periods beginning after December 15, 2018. In November 2018, FASB issued ASU 2018-19“Codification Improvements to topic 326, Financial Instruments-Credit Losses”. The amendments in this update clarify that operating lease receivables are not within the scope of ASC 326-20 and should instead be accounted for under the new leasing standard, ASC 842. In April 2019, FASB issued ASU 2019-04 “Codification Improvements to topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments”. In May 2019, FASB issued ASU 2019-05, “Financial Instruments-Credit Losses (Topic 326): Targeted Transition Relief”. The amendments in this update provide entities that have certain instruments within the scope of Subtopic 326-20, Financial Instruments-Credit Losses-Measured at Amortized Cost, with an option to irrevocably elect the fair value option in Subtopic 825-10, Financial Instruments-Overall, applied on an instrument-by-instrument basis for eligible instruments, upon adoption of Topic 326. The fair value option election does not apply to held-to-maturity debt securities. An entity that elects the fair value option should subsequently apply the guidance in Subtopics 820-10, Fair Value Measurement-Overall, and 825-10. The Company is currently assessing the impact that adopting this new accounting guidance will have on its consolidated financial statements.
