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 long-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 December 31, 2017, there were outstanding: 147,797,720 common units and 3,016,284 general partnership units. As of December 31, 2017, Navios Holdings owned a 20.8% interest in Navios Partners, which included a 2.0% general partner interest. Navios Containers Navios Maritime Containers Inc. (“Navios Containers”), an affiliate of the Company, was established in the Republic of the Marshall Islands on April 28, 2017. The Company is a growth vehicle dedicated to the container sector of the maritime industry. On June 12, 2017, Navios Containers also registered and began trading on the Norwegian Over-The-Counter Market under the ticker NMCI. On June 8, 2017, Navios Containers closed its private placement and issued 10,057,645 shares for total gross proceeds of $50,288 at a subscription price of $5.00 per share. Navios Partners invested $30,000 and received 59.7% of the equity, and Navios Holdings invested $5,000 and received 9.9% of the equity of Navios Containers. Each of Navios Partners and Navios Holdings also received warrants, with a five-year term, for 6.8% and 1.7% of the equity, respectively. Navios Containers used the proceeds to acquire five 4,250 TEU vessels from Navios Partners for a total purchase price of $64,000. These vessels, first acquired by Navios Partners from Rickmers Maritime Trust Pte. (“Rickmers Trust”), are employed on charters with a net daily charter rate of $26,850. The charters expire in 2018 and early 2019. In addition, Navios Containers acquired all the rights under the acquisition agreements entered into between Navios Partners and Rickmers Trust to purchase the remaining nine vessels (the “RMT Fleet”) in the original 14-vessel container fleet. On August 29, 2017, Navios Containers closed its private placement of 10,000,000 shares at a subscription price of $5.00 per share, resulting in gross proceeds of $50,000. Navios Partners invested $10,000 and received 2,000,000 shares. Navios Partners and Navios Holdings also received warrants, with a five-year term, for 6.8% and 1.7% of the equity, respectively. As a result, from August 29, 2017, Navios Containers is considered an affiliate entity and the investment in Navios Containers is accounted for under the equity method due to the Company’s significant influence over Navios Containers (see Note 3 – Acquisition/Deconsolidation). On November 9, 2017, Navios Containers closed a private placement of 9,090,909 shares at a subscription price of $5.50 per share, resulting in gross proceeds of approximately $50,000. Navios Partners invested $10,000 and received 1,818,182 shares. Navios Partners also received warrants, with a five-year term, for 6.8% of the newly issued equity. In connection with the Navios Containers’ deconsolidation, the Company recognized an amount of $174 related to the dilution gain of its investment in Navios Containers. The amount was recognized in the Statements of Operations under the caption of “Equity in net earnings of affiliated companies” for the year ended December 31, 2017. As of December 31, 2017, Navios Partners held 9,818,182 common shares and received 33.7% of the equity, and Navios Holdings held 1,000,000 common shares and received 3.4% of the equity of Navios Containers.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]

Summary of Significant Accounting Policies

NOTE 2 – 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).

The Company elected to early adopt the requirements of ASU 2017-01 effective beginning the second quarter ending June 30, 2017 and applied this guidance prospectively in the current period presented in the Company’s condensed consolidated financial information in connection with the acquisition of the five container vessels (see Note 7 — Vessels, net). The early adoption of this ASU did not have a material effect on the Company’s consolidated financial statements.

(b) Principles of consolidation: The accompanying 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.

The accompanying consolidated financial statements include the following entities:

(*)Not a vessel-owning subsidiary and only holds right to charter-in contracts.

(**)The vessel was classified as held for sale as at December 31, 2016 and was sold on January 12, 2017 (see Note 7 – Vessels, net).

(***)The vessel was sold on April 21, 2017 (see Note 7 – Vessels, net).

(****) The vessel was sold on December 21, 2017 (see Note 7 – Vessels, net).

Investments in Affiliates: Affiliates are entities over which the Company generally has between 20% and 50% of the voting rights, or over which the Company has significant influence, but it does not exercise control. Investments in these entities are accounted for under the equity method of accounting. Under this method, the Company records an investment in the stock of an affiliate at cost, and adjusts the carrying amount for its share of the earnings or losses of the affiliate subsequent to the date of investment and reports the recognized earnings or losses in income. Dividends received from an affiliate reduce the carrying amount of the investment. The Company recognizes gains and losses in earnings for the issuance of shares by its affiliates, provided that the issuance of such shares qualifies as a sale of such shares. When the Company’s share of losses in an affiliate equals or exceeds its interest in the affiliate, the Company does not recognize further losses, unless the Company has incurred obligations or made payments on behalf of the affiliate.

Affiliates included in the financial statements accounted for under the equity method: In the consolidated financial statements of Navios Partners, the following entities are included as affiliates and are accounted for under the equity method for such periods: (i) Navios Containers and its subsidiaries (ownership interest as of December 31, 2017 was 33.7%); (ii) Navios Europe I and its subsidiaries (ownership interest as of December 31, 2017 was 5.0%); and (iii) Navios Europe II and its subsidiaries (ownership interest as of December 31, 2017 was 5.0%).

(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, 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: As of December 31, 2017 and 2016, restricted cash includes an amount of $386 and $2,228, respectively, which related to amounts held in retention accounts in order to service debt and interest payments, as required by Navios Partners’ credit facilities and an amount of $5,500 held as security in the form of a letter of guarantee relating to the chartering of a vessel. As of December 31, 2017 and 2016, the restricted cash was $5,886 and $7,728, respectively.

(f) Accounts Receivable, Net: The amount shown as accounts receivable, net at each balance sheet date includes receivables from charterers for hire, freight and demurrage billings, net of a provision for doubtful accounts. At each balance sheet date, all potentially uncollectible accounts are assessed individually for purposes of determining the appropriate provision for doubtful accounts. The allowance for doubtful accounts as of December 31, 2017 and 2016 was $1,495 and $0, respectively.

(g) Inventories: Inventories, which are comprised of bunkers due to freight voyages, are 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 any material expenses incurred upon acquisition (improvements and delivery expenses). Vessels acquired in an asset acquisition or in a business combination are recorded at fair value. 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 our drybulk and container vessels 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 affects depreciation expense in the period of the revision and future periods. The management after considering current market trends for scrap rates and 10-year average historical scrap rates of the residual values of the Company’s vessels, estimates scrap value at a rate of $340 per LWT.

Management estimates the useful life of our vessels to be 25 and 30 years from the drybulk and container vessel’s original construction, respectively. 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. As of December 31, 2016, MSC Cristina had been classified as held for sale as the relevant criteria for the classification were met (see Note 7 – Vessels, net). No assets were classified as held for sale as of December 31, 2017.

(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 related to the vessel and the related carrying value of the intangible assets with respect to the time charter agreement attached to that vessel or the carrying value of deposits for newbuildings. Within the shipping industry, vessels are customarily bought and sold with a charter attached. The value of the charter may be favorable or unfavorable when comparing the charter rate to then current market rates. The loss recognized either on impairment (or on disposition) will reflect the excess of carrying value over fair value (selling price) for the vessel asset group.

During the fourth quarter of fiscal year 2017, the Company concluded that events occurred and circumstances had changed, which indicated that potential impairment of Navios Partners’ long-lived assets may exist. These indicators included volatility in the spot market and the related impact of the current drybulk and container sector has on management’s expectation for future revenues. As a result, Navios Partners performed step one of the impairment assessment of the Company’s long-lived assets by comparing the undiscounted projected net operating cash flows for each vessel to its carrying value together with the carrying value of deferred drydock and special survey costs related to the vessel and the carrying value of the related intangible assets, if applicable. The significant factors and assumptions the Company used in the undiscounted projected net operating cash flow analysis included: determining the projected net operating cash flows by considering the charter revenues from existing time charters for the fixed fleet days (Navios Partners’ remaining charter agreement rates) and an estimated daily time charter equivalent for the unfixed days (based on a combination of one-year average historical time charter rates for the first year and 10-year average historical one-year time charter rates for the remaining period, adjusted for outliers) over the remaining economic life of each vessel, net of brokerage and address commissions, and excluding days of scheduled off-hires, management fees fixed until December 2019 and thereafter assuming an increase of 1.0% every second year and utilization rate of 98.6% based on the fleet’s historical performance.

As of December 31, 2017, our assessment concluded that step two of the impairment analysis was required for one of our 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 $30,304 for this 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 “Vessel impairment losses” in the consolidated Statements of Operations. The assessment performed for 2016 and 2015 did not indicate a step two was necessary for the Company’s other vessels held and used (see Note 7 – Vessels, net).

As of December 31, 2017 and 2016, an impairment loss of $2,373, $17,193 and $10,008, respectively, was also recognized in connection with the committed sale of the Navios Gemini S, the MSC Cristina and the Navios Apollon 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 impairment loss was presented under the caption “Vessel impairment losses” in the consolidated Statements of Operations. Impairment loss recognized amounted to $32,677, $27,201 and $0 for the years ended December 31, 2017, 2016 and 2015, respectively.

(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, 2017, 2016 and 2015, the amortization expense was $7,172, $6,381 and $4,043, respectively.

(l) Deferred Financing Cost: Deferred financing costs include fees, commissions and legal expenses associated with obtaining or modifying credit facilities. Deferred financing 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 included in interest expense. Amortization and write-off of deferred financing costs, including amortization of debt discount, for each of the years ended December 31, 2017, 2016 and 2015 were $9,744, $4,003 and $3,727, respectively.

(m) Investments in Equity Securities: Navios Partners evaluates its investments in Navios Europe I, Navios Europe II and Navios Containers for other-than-temporary impairment (“OTTI”) on a quarterly basis. Consideration is given to (i) the length of time and the extent to which the fair value has been less than the carrying value, (ii) the financial condition and near-term prospects of Navios Europe I, Navios Europe II and Navios Containers, and (iii) the intent and ability of the Company to retain its investment in Navios Europe I, Navios Europe II and Navios Containers, for a period of time sufficient to allow for any anticipated recovery in fair value.

(n) Intangible Assets and Liabilities: Navios Partners’ intangible assets and liabilities consist of favorable lease terms and unfavorable lease terms. When intangible assets or liabilities associated with the acquisition of a vessel are identified, they 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, expected future charter rates, the level of utilization of its vessels and its weighted average cost of capital. 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 in the Statements of Operations under the caption “Depreciation and amortization” line item.

The amortizable value of favorable leases would be considered impaired if its carrying value could not be recovered from the future undiscounted cash flows associated with the asset. Management, after considering various indicators, performed on impairment test which included intangible assets as described in paragraph (j) above. As of December 31, 2017, there was no impairment of intangible assets.

(o) 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 caption “Other income” or “Other expense”, for each of the years ended December 31, 2017, 2016 and 2015 were $54, $11, and $19, respectively.

(p) 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 agreement, participates in Protection and Indemnity (P&I) insurance coverage plans provided by mutual insurance societies known as P&I clubs. Under the terms of these plans, participants may be required to pay additional premiums (supplementary calls) to fund operating deficits incurred by the clubs (“back calls”). Obligations for back calls are accrued annually based on information provided by the P&I clubs.

(q) 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. For the period from April 28, 2017 to August 29, 2017, the Company had two reportable segments from which it derived its revenues: Navios Partners Operations and Navios Containers Operations. The reportable segments reflect the internal organization of the Company whereby the Chief Operating Decision Maker (“CODM”) reviews the discrete financial information of the Navios Partners’ controlled fleet and the Navios Containers’ controlled fleet.

(r) Revenue and Expense Recognition: Revenue is recorded when services are rendered, under a signed charter agreement or other evidence of an arrangement, the price is fixed or determinable, and collection is reasonably assured. Revenue is generated from time charter of vessels.

Voyage revenues for the transportation of cargo are recognized ratably over the estimated relative transit time of each voyage. A voyage is deemed to commence when a vessel arrives at the loading port, as applicable under the contract, and is deemed to end upon the completion of the discharge of the current cargo. Under a voyage charter, the Company agrees to provide a vessel for the transportation of specific goods between specific ports in return for payment of an agreed upon freight rate per ton of cargo.

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.

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) or the Baltic Dry Index 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. Profit sharing for the years ended December 31, 2017, 2016 and 2015 amounted to $1,819, $(9,123) and $(2,559), respectively.

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 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. Revenue for vessels operating in pooling arrangements amounted to $6,058, $3,949 and $0, for the years ended December 31, 2017, 2016 and 2015, respectively. The allocation of such net revenue may be subject to future adjustments by the pool however, such changes are not expected to be material.

Deferred Revenue and Cash Received in Advance: Deferred revenue primarily relates to cash received from charterers prior to it being earned and the compensation received for the future reduction in the daily hire rates payable by HMM. These amounts are recognized as revenue over the voyage or charter period.

Time Charter and Voyage Expenses: Time charter and voyage expenses comprise all expenses related to each particular voyage, including time charter hire paid and voyage freight paid, bunkers, port charges, canal tolls, cargo handling, agency fees and brokerage commissions. Also included in time charter and voyage expenses are provision for losses on time charters and voyages in progress at year-end, direct port terminal expenses and other miscellaneous expenses. Time charter expenses are expensed over the period of the time charter and voyage expenses are recognized as incurred.

Direct Vessel Expenses: Direct vessel expenses comprise the amortization related to drydocking and special survey costs of certain vessels of Navios Partners’ fleet.

Prepaid Voyage Costs: Prepaid voyage costs relate to cash paid in advance for expenses associated with voyages. These amounts are recognized as expenses over the voyage or charter period.

Management Fees: Pursuant to the amended Management Agreement, in each of October 2013, August 2014, February 2015 and February 2016, the Manager, a wholly owned subsidiary of Navios Holdings, provides commercial and technical management services to Navios Partners’ vessels for a daily fee of: (a) $4.10 daily rate per Ultra-Handymax vessel; (b) $4.20 daily rate per Panamax vessel; (c) $5.25 daily rate per Capesize vessel; (d) $6.70 daily rate per Container vessel of TEU 6,800; (e) $7.40 daily rate per Container vessel of TEU 8,000; and (f) $8.75 daily rate per very large Container vessel of more than TEU 13,000 through December 31, 2017. On November 14, 2017, Navios Partners agreed to extend the duration of its existing Management Agreement with the Manager until December 31, 2022 and to fix the rate for shipmanagement services of its owned fleet through December 31, 2019, effective from January 1, 2018. The new management fees, excluding drydocking expenses, will be: (a) $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 Container vessel of TEU 6,800; (e) $7.40 daily rate per Container vessel of more than TEU 8,000 and (f) $8.75 daily rate per very large Container vessel of more than TEU 13,000. Drydocking expenses under this agreement are reimbursed by Navios Partners at cost at occurrence.

General and Administrative Expenses: Pursuant to the Administrative Services Agreement dated November 16, 2007, the Manager also provides administrative services to Navios Partners, which include bookkeeping, audit and accounting services, legal and insurance services, administrative and clerical services, banking and financial services, advisory services, client and investor relations and other. The Manager is reimbursed for reasonable costs and expenses incurred in connection with the provision of these services. Navios Partners extended the duration of its existing Administrative Services Agreement with the Manager pursuant to the same terms, until December 31, 2022.

(s) 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 and long-term debt. 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: Navios Partners’ activities expose it to a variety of financial risks including fluctuations in future freight rates, time charter hire rates, fuel prices, credit and interest rates risk. Risk management is carried out under policies approved by executive management. Guidelines are established for overall risk management, as well as specific areas of operations.

Credit risk: Navios Partners closely monitors its credit exposure to customers and counter-parties for credit risk. Navios Partners has entered into the management agreement with the Manager, pursuant to which the Manager agreed to provide commercial and technical management services to Navios Partners. When negotiating on behalf of Navios Partners’ various vessel employment contracts, the Manager has policies in place to ensure that it trades with customers and counterparties with an appropriate credit history.

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, 2017, our customers representing 10% or more of total revenues were HMM and Yang Ming which accounted for approximately 26.8% and 12.0%, respectively, of total revenues. For the year ended December 31, 2016, Navios Partners’ customers representing 10% or more of total revenues were HMM, Yang Ming and Mediterranean Shipping Co. S.A. which accounted for approximately 29.6%, 13.0% and 11.6%, respectively, of total revenues. For the year ended December 31, 2015, Navios Partners’ customers representing 10% or more of total revenues were HMM, Navios Corporation and Yang Ming, which accounted for 24.0%, 17.4% and 11.4%, respectively, of total revenues. No other customers accounted for 10% or more of total revenues for any of the years presented.

Liquidity Risk: Prudent liquidity risk management implies maintaining sufficient cash and marketable securities, the availability of funding through an adequate amount of committed credit facilities and the ability to close out market positions. Navios Partners monitors cash balances appropriately to meet working capital needs.

Foreign Exchange Risk: Foreign currency transactions are translated into the measurement currency rates prevailing at the dates of transactions. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation of monetary assets and liabilities denominated in foreign currencies are recognized in the consolidated Statements of Operations.

(t) Cash Distribution: As per the Partnership Agreement, within 45 days following the end of each quarter, to the extent and as may be declared by the Board, an amount equal to 100% of Available Cash with respect to such quarter shall be distributed to the partners as of the record date selected by the Board of Directors.

Available Cash: Generally means, for each fiscal quarter, all cash on hand at the end of the quarter:

•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 US GAAP and should not be considered as an alternative to net income or any other indicator of Navios Partners’ performance required by US GAAP.

Cash distributions are recorded in the Company’s financial statements in the period in which they are declared. Navios Partners paid $0, $0 and $132,306 to its holders of record of common and general partner units during the years ended December 31, 2017, 2016 and 2015, respectively. 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. The amount of any distributions paid under Navios Partners’ policy and the decision to make any distribution is determined by its board of directors, taking into consideration the terms of its partnership agreement. (see also Note 24 – Subsequent Events)

Maintenance and Replacement Capital Expenditures: Maintenance and Replacement capital expenditures are those capital expenditures required to maintain over the long-term the operating capacity of or the revenue generated by Navios Partners’ capital assets, and expansion capital expenditures are those capital expenditures that increase the operating capacity of or the revenue generated by the capital assets. To the extent, however, that capital expenditures associated with acquiring a new vessel increase the revenues or the operating capacity of our fleet, those capital expenditures would be classified as expansion capital expenditures. As of December 31, 2017, 2016 and 2015, Maintenance and Replacement capital expenditures reserve approved by the Board of Directors was $14,859, $11,899 and $13,811, respectively.

(u) Stock-based compensation: In December 2017 and 2016, Navios Partners granted restricted common units to its directors and/or officers which are based on service conditions only and vest over three years. The fair value of restricted 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. Compensation expense for the awards that vest upon achievement of the performance criteria is recognized when it is probable that the performance criteria will be met and are being accounted for as equity. The effect of compensation expense arising from the restricted units described above amounted to $1,904 and $93 as of December 31, 2017 and 2016, 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, 2017 and 2016. As of December 31, 2017, 686,665 restricted common units were vested.

(v) 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 and Liberia, the countries of the vessel-owning subsidiaries’ incorporation and vessels’ registration, the vessel-owning subsidiaries are subject to registration and tonnage taxes which have been included in vessel operating expenses in the accompanying consolidated Statements of Operations.

(w) (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.

(x) 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 in March 2014), Navios Holdings and Navios Partners entered into an agreement (the “Navios Holdings Guarantee”) by which Navios Holdings agreed to provide supplemental credit default insurance with a maximum cash payment of $20.0 million. During the year ended December 31, 2017 and 2016, the Company submitted claims for charterers’ default under this agreement to Navios Holdings for a total amount of $7.2 million and $9.2 million, respectively, net of applicable deductions, of which $7.6 million and $9.6 million, respectively, was presented under the caption “Other income”.

(y) Leases: Vessel leases where Navios Partners is regarded as the lessor are classified as either finance leases or operating 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, refer to Note 2(r).

For charters classified as operating leases where Navios Partners is regarded as the lessee, the expense is recognized on a straight line basis over the rental periods of such charter agreements.

(z) 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.

(aa) Recent Accounting Pronouncements: In May 2017, FASB issued Accounting Standard Update No. 2017-09, “Compensation—Stock Compensation (Topic 718)”. This update provides clarity and reduces both diversity in practice and cost and complexity when applying the guidance in Topic 718 to a change to the terms or conditions of a share-based payment award. The amendments in this update affect any entity that changes the terms or conditions of a share-based payment award and are effective for all entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period, for public business entities for reporting periods for which financial statements have not yet been issued and all other entities for reporting periods for which financial statements have not yet been made available for issuance. The amendments in this update should be applied prospectively to an award modified on or after the adoption date. The adoption of this new accounting standard is not expected to have material impact on the Company’s results of operations, financial position or cash flows.

In February 2017, FASB issued Accounting Standard Update No. 2017-05, “Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20)”. This update clarifies the scope of Subtopic 610-20 “Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets” and provides guidance for partial sales of nonfinancial assets. Subtopic 610-20, which was issued in May 2014 as a part of ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)”, provides guidance for recognizing gains and losses from the transfer of nonfinancial assets in contracts with noncustomers. The amendments in ASU 2017-05 are effective at the same time as the amendments in ASU 2014-09. Therefore, for public entities, the amendments are effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. The Company is currently assessing the impact that adopting this new accounting guidance will have on its consolidated financial statements.

In January 2017, FASB issued Accounting Standard Update No. 2017-03 “Accounting Changes and Error Corrections (Topic 250) and Investments-Equity Method and Joint Ventures (Topic 323).” The ASU amends the Codification for SEC staff announcements made at recent Emerging Issues Task Force (EITF) meetings. The SEC guidance that specifically relates to our Consolidate Financial Statement was from the September 2016 meeting, where the SEC staff expressed its expectations about the extent of disclosures registrants should make about the effects of the new FASB guidance as well as any amendments issued prior to adoption, on revenue (ASU 2014-09), leases (ASU 2016-02) and credit losses on financial instruments (ASU 2016-13) in accordance with SAB Topic 11.M. Registrants are required to disclose the effect that recently issued accounting standards will have on their financial statements when adopted in a future period. In cases where a registrant cannot reasonably estimate the impact of the adoption, then additional qualitative disclosures should be considered. The ASU incorporates these SEC staff views into ASC 250 and adds references to that guidance in the transition paragraphs of each of the three new standards. The adoption of this new accounting guidance did not have a material effect on the Company’s Consolidated Financial Statements.

In November 2016, FASB issued Accounting Standards Update No. 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash”. This update addresses the classification and presentation of changes in restricted cash on the statement of cash flows under Topic 230, Statement of Cash Flows. The amendments are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted for all entities. The Company is currently assessing the impact that adopting this new accounting guidance will have on its consolidated financial statements.

In August 2016, FASB issued Accounting Standards Update No. 2016-15, “Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments”. This update addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The amendments are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. This update was adopted as from January 1, 2018 and applied on a retrospective basis. The Company has assessed each of the eight specific presentation issues and determined that the adoption of this ASU does not have a material impact on the Company’s consolidated financial statements.

In February 2016, FASB issued ASU 2016-02, “Leases (Topic 842)”. ASU 2016-02 will apply to both capital (or finance) leases and operating leases. According to ASU 2016-02, lessees will be required to recognize assets (right of use asset) and liabilities (lease liability) on the balance sheet for both types of leases – capital (or finance) leases and operating leases – with terms greater than 12 months. ASU 2016 – 02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted.

This guidance requires companies to identify lease and non-lease components of a lease agreement. Lease components relate to the right to use the leased asset and non-lease components relate to payments for goods or services that are transferred separately from the right to use the underlying asset. Total lease consideration is allocated to lease and non-lease components on a relative standalone basis. The recognition of revenues related to lease components will be governed by ASC 842 while revenue related to non-lease components will be subject to ASC 606.

In January 2018, the FASB issued a proposed amendment to ASU 842, Leases, that would provide an entity the optional transition method to initially account for the impact of the adoption with a cumulative adjustment to accumulated deficit on the effective date of the ASU, January 1, 2019 rather than January 1, 2017, which would eliminate the need to restate amounts presented prior to January 1, 2019. In addition, this proposed amendment, lessors can elect, as a practical expedient, not to allocate the total consideration to lease and non-lease components based on their relative standalone selling prices. If adopted, this practical expedient will allow lessors to elect a combined single lease component presentation if (i) the timing and pattern of the revenue recognition of the combined single lease component is the same, and (ii) the related lease component and, the combined single lease component would be classified as an operating lease.

ASC 842 provides practical expedients that allow entities to not (i) reassess whether any expired or existing contracts are considered or contain leases; (ii) reassess the lease classification for any expired or existing leases; and (iii) reassess initial direct costs for any existing leases.

The Company plans to adopt the standard on January 1, 2019 and expects to elect the use of practical expedients. If the proposed amendment to ASU 842 is adopted, the Company would elect the transition method for adoption as described above.

The Company has not completed its analysis of this ASU. Based on a preliminary assessment, the Company is expecting that the adoption will not have a material effect on its financial statements since the Company is primarily a lessor and the changes are fairly minor. If the proposed practical expedient mentioned above is adopted and elected, goods and services embedded in the charter contract that qualify as non-lease components will be combined under a single lease component presentation. However, without the proposed practical expedient, the Company expects that it will continue to recognize the lease revenue component using an approach that is substantially equivalent to existing guidance. The components of the charter hire that are categorized as lease components will generally be a fixed rate per day with revenue recognized straight line over the lease contract. Other goods and services that are categorized as non-lease components will be recognized at either a point in time or over time based on the pattern of transfer of the underlying goods or services to our charterers.

The Company is continuing its assessment of other miscellaneous leases and may identify additional impacts this guidance will have on its consolidated financial statements and disclosures. The Company currently does not have any other miscellaneous leases that are greater than 12 months and the Company is the lessee that would be impacted by the adoption of this standard.

In January 2016, FASB issued Accounting Standards Update No. 2016-01, “Financial Instruments – Overall (Subtopic 825-10) – Recognition and Measurement of Financial Assets and Financial Liabilities”. The amendments in this update require an entity (i) to measure equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) at fair value with changes in fair value recognized in net income; (ii) to perform a qualitative assessment to identify impairment in equity investments without readily determinable fair values; (iii) to present separately in other comprehensive income the fair value of a liability resulting from a change in the instrument-specific credit risk; and (iv) to present separately financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet. The amendments also eliminate the requirement, for public business entities, to disclose the methods and significant assumptions used to estimate the fair value of financial instruments measured at amortized cost on the balance sheet and clarify that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. For public business entities, the update is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The adoption of this new standard is not expected to have a material impact on the Company’s results of operations, financial position or cash flows.

In May 2014, FASB issued ASU 2014-09, “Revenue from Contracts with Customers”, clarifying the method used to determine the timing and requirements for revenue recognition on the statements of income. Under the new standard, an entity must identify the performance obligations in a contract, the transaction price and allocate the price to specific performance obligations to recognize the revenue when the obligation is completed. The amendments in this update also require disclosure of sufficient information to allow users to understand the nature, amount, timing and uncertainty of revenue and cash flow arising from contracts. In August 2015, the FASB issued ASU 2015-14 which deferred the effective date of ASU 2014-09 for all entities by one year. The standard will be effective for public entities for annual reporting periods beginning after December 15, 2017 and interim periods therein.

The Company will adopt the standard as of January 1, 2018 and will utilize the modified retrospective approach and is expecting that the adoption will not have a material effect on its financial statements. The Company has chartered certain of its vessels since inception in time charter agreements and in this respect revenue is accounted under ASC 840 Leases. The Company also operates certain of its vessels under voyage contracts, contracts for which currently revenue is recognized ratably from when a vessel becomes available for loading to the completion of the discharge of the current cargo, provided an agreed non-cancelable charter between the Company and the charterer is in existence. Upon adoption, the Company will recognize revenue ratably from the vessel’s arrival at the loading port, as applicable under the contract, 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. The estimated impact of the adoption of this standard is expected to be a minimal change in operating revenues and expenses and net income/ (loss).

Disclosure Text Block [Abstract]
Acquisition/ Deconsolidation	NOTE 3: ACQUISITION/DECONSOLIDATION On June 7, 2017, after its special meeting of stockholders, Navios Containers announced the approval of the acquisition of five 4,250 TEU container vessels from Navios Partners and the charter-out contracts for an aggregate purchase price of $64,000. Out of the total purchase price an amount of $40,000 was paid from the proceeds of the private placement on June 8, 2017 and the $24,000 balance as a seller’s credit by Navios Partners for a period of up to 90 days from the purchase date at LIBOR plus 375 bps. On June 30, 2017 and August 29, 2017, Navios Containers paid to Navios Partners $10,000 and $14,000, respectively, in relation to this agreement. On August 29, 2017, Navios Containers closed its private placement of 10,000,000 shares at a subscription price of $5.00 per share, resulting in gross proceeds of $50,000. Navios Partners invested $10,000 and received 2,000,000 shares. Navios Partners and Navios Holdings also received warrants, with a five-year term, for 6.8% and 1.7% of the equity, respectively. Immediately after the Navios Containers’ private placement, Navios Partners’ ownership of the outstanding voting stocks of Navios Containers decreased to 39.9% and Navios Partners no longer controls a majority of the voting power of Navios Containers. From that date onwards, Navios Containers has been considered as an affiliate entity of Navios Partners and not as a controlled subsidiary of the Company and the investment in Navios Containers has been accounted for under the equity method due to the Company’s significant influence over Navios Containers. On August 29, 2017, based on the equity method, the Company recorded an investment in Navios Containers of $40,000, which represents the fair value of the common stocks that were held by Navios Partners on such date. The remeasurement of the retained investment in Navios Containers was determined by reference to the share price of Navios Containers in the Norwegian Over-The-Counter Market and had no impact in Company’s income statement. On August 29, 2017, the Company calculated a gain on change in control of $4,068 which is equal to the fair value of the Company’s investment in Navios Containers of $30,000 (including the cash paid for retaining a 39.9%) less the Company’s 59.7% interest in Navios Containers’ net assets of approximately $43,494 on August 29, 2017. As of December 31, 2017, Navios Partners held 9,818,182 common shares and received 33.7% of the equity, and Navios Holdings held 1,000,000 common shares and received 3.4% of the equity of Navios Containers. Each of Navios Partners and Navios Holdings also received warrants, with a five-year term, for 6.8% and 1.7% of the equity, respectively.

Cash on hand and at banks	$24,047	$17,360

Total cash and cash equivalents	$24,047	$17,360

Short-term deposits and highly liquid funds relate to amounts held in banks for general financing purposes and represent deposits with an original maturity of less than three months.

Cash deposits and cash equivalents in excess of amounts covered by government-provided insurance are exposed to loss in the event of non-performance by financial institutions. Navios Partners does maintain cash deposits and equivalents in excess of government-provided insurance limits. Navios Partners also minimizes exposure to credit risk by dealing with a diversified group of major financial institutions.

Restricted cash, at each of December 31, 2017 and December 31, 2016, included $386 and $2,228, 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. Also, as of December 31, 2017 and December 31, 2016, an amount of $5,500 was held as security in the form of a letter of guarantee, relating to the chartering of a vessel.

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. For the year ended December 31, 2017, two customers accounted for 26.8% and 12.0%, respectively, of the Company’s revenue. For the year ended December 31, 2016, three customers accounted for 29.6%, 13.0% and 11.6%, respectively, of the Company’s revenue and for the year ended December 31, 2015, three customers accounted for 24.0%, 17.4% and 11.4% of the Company’s revenue. Both customers for the fiscal year 2017 were the same with the prior years.

FAIR VALUE OF FINANCIAL INSTRUMENTS [ABSTRACT]

Fair Value of Financial Instruments

NOTE 12 – 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 and restricted cash: The carrying amounts reported in the consolidated balance sheets for interest bearing deposits and money market funds approximate their fair value because of the short maturity of these investments.

Other long-term debt, net: The book value has been adjusted to reflect the net presentation of deferred finance costs. The outstanding balance of floating rate loans continues to approximate its fair value, excluding the effect of any deferred finance costs.

Term Loan B Credit 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.

Due to related parties, long-term: The carrying amount of due to related parties, long-term reported in the balance sheet approximates its fair value due to the long-term nature of these payables.

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.

The estimated fair values of the Navios Partners’ financial instruments are as follows:

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. Valuation of these items does not entail a significant amount of judgment.

Level II: Inputs other than quoted prices included in Level I that are observable for the asset or liability through corroboration with market data at the measurement date.

Level III: Inputs that are unobservable. The Company did not use any Level III inputs as of December 31, 2017 and December 31, 2016.

NOTE 14 – SEGMENT INFORMATION

For the period from April 28, 2017 to August 29, 2017, the Company had two reportable segments from which it derived its revenues: Navios Partners Operations and Navios Containers Operations. The reportable segments reflect the internal organization of the Company whereby the Chief Operating Decision Maker (“CODM”) reviews the discrete financial information of the Navios Partners’ controlled fleet and the Navios Containers’ controlled fleet.

The Company measures segment performance based on net income/(loss) attributable to Navios Partners common unitholders. Summarized financial information concerning each of the Company’s reportable segments is as follows:

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 container vessels 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	Dec. 31, 2017
INCOME TAXES [Abstract]
Income Taxes	NOTE 15 – INCOME TAXES Marshall Islands, Malta and Liberia do not impose a tax on international shipping income. Under the laws of Marshall Islands, Malta and Liberia, the countries of the vessel-owning subsidiaries’ incorporation and vessels’ registration, the vessel-owning subsidiaries are subject to registration and tonnage taxes which have been included in vessel operating expenses in the accompanying consolidated Statements of Operations. In accordance with the currently applicable Greek law, foreign flagged vessels that are managed by Greek or foreign ship management companies having established an office in Greece are subject to duties towards the Greek state which are calculated on the basis of the relevant vessel’s tonnage. The payment of said duties exhausts the tax liability of the foreign ship owning company and the relevant manager against any tax, duty, charge or contribution payable on income from the exploitation of the foreign flagged vessel. Pursuant to Section 883 of the Internal Revenue Code of the United States, U.S. source income from the international operation of ships is generally exempt from U.S. income tax if the company operating the ships meets certain incorporation and ownership requirements. Among other things, in order to qualify for this exemption, the company operating the ships must be incorporated in a country which grants an equivalent exemption from income taxes to U.S. corporations. All the vessel-owning subsidiaries satisfy these initial criteria. In addition, these companies must meet an ownership test. The management of Navios Partners believes that this ownership test was satisfied prior to the IPO by virtue of a special rule applicable to situations where the ship operating companies are beneficially owned by a publicly traded company. Although not free from doubt, management also believes that the ownership test will be satisfied based on the trading volume and ownership of Navios Partners’ units, but no assurance can be given that this will remain so in the future.

CASH DISTRIBUTIONS AND EARNINGS PER UNIT [Abstract]

Cash Distributions and Earnings Per Unit

NOTE 21 – CASH DISTRIBUTIONS AND EARNINGS PER UNIT

Navios Partners intends to make distributions to the holders of common units on a quarterly basis, to the extent and as may be declared by the Board and to the extent it has sufficient cash on hand to pay the distribution after the Company establishes cash reserves and pays fees and expenses. There is no guarantee that Navios Partners will pay a quarterly distribution on the common 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. (see also Note 24 – Subsequent Events) The amount of any distributions paid under Navios Partners’ policy and the decision to make any distribution is determined by its 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 $0.35	98%	2%
First Target Distribution	up to $0.4025	98%	2%
Second Target Distribution	above $0.4025 up to $0.4375	85%	15%
Third Target Distribution	above $0.4375 up to $0.525	75%	25%
Thereafter	above $0.525	50%	50%

The first 98% of the quarterly distribution is paid to all common units holders. The incentive distributions rights (held by the General Partner) apply only after a minimum quarterly distribution of $0.4025.

On January 26, 2015, the Board of Directors of Navios Partners authorized its quarterly cash distribution for the three month period ended December 31, 2014 of $0.4425 per unit. The distribution was paid on February 13, 2015 to all holders of record of common and general partner units on February 11, 2015, which included the unitholders participating in the February 2015 offering (See Note 13 — Issuance of units). The aggregate amount of the declared distribution was $38,097.

On April 28, 2015, the Board of Directors of Navios Partners authorized its quarterly cash distribution for the three month period ended March 31, 2015 of $0.4425 per unit. The distribution was paid on May 14, 2015 to all holders of record of common and general partner units on May 13, 2015. The aggregate amount of the declared distribution was $38,097.

On July 23, 2015, the Board of Directors of Navios Partners authorized its quarterly cash distribution for the three month period ended June 30, 2015 of $0.4425 per unit. The distribution was paid on August 14, 2015 to all holders of record of common and general partner units on August 13, 2015. The aggregate amount of the declared distribution was $38,097.

On November 3, 2015, the Board of Directors of Navios Partners authorized its quarterly cash distribution for the three month period ended September 30, 2015 of $0.2125 per unit. The distribution was paid on November 13, 2015 to all holders of record of common and general partner units on November 12, 2015. The aggregate amount of the declared distribution was $18,015.

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 (losses)/earnings per unit is determined by dividing net (loss)/income 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 the years ended December 31, 2017, 2016 and 2015.

The calculations of the basic and diluted earnings per unit are presented below.


	Year Ended December 31, 2017	Year Ended December 31, 2016	Year Ended December 31, 2015
Net (loss)/income	$(15,090)	$(52,549)	$41,805
Earnings attributable to:
Common unitholders	(14,788)	(51,498)	39,825
Weighted average units outstanding (basic and diluted)
Common unitholders	132,610,330	83,107,066	82,437,128
Earnings per unit (basic and diluted):
Common unitholders	$(0.11)	$(0.62)	$0.48
Earnings per unit — distributed (basic and diluted):
Common unitholders	$—	$—	$1.11
Loss per unit — undistributed (basic and diluted):
Common unitholders	$(0.11)	$(0.62)	$(0.63)

Potential common units of 1,353,335 and 0 relating to unvested restricted common units for the years ended December 31, 2017 and 2016 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.

Concentration of credit risk with respect to accounts receivable	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.
