Description of Business	Dec. 31, 2012
Description of Business [Abstract]
Description of Business	NOTE 1 - DESCRIPTION OF BUSINESS Navios Maritime Partners L.P. (“Navios Partners”), 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 by Navios Maritime Holdings Inc. (“Navios Holdings”), a vertically integrated seaborne shipping and logistics company with over 55 years of operating history in the drybulk shipping industry. Navios GP L.L.C. (the “General Partner”), a wholly owned subsidiary of Navios Holdings, was also formed on that date to act as the general partner of Navios Partners and received a 2% general partner interest in Navios Partners. Navios Partners is engaged in the seaborne transportation services of a wide range of drybulk commodities including iron ore, coal, grain and fertilizer, 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. 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 pursuant to which the Manager provides Navios Partners commercial and technical management services; (b) an administrative services agreement with the Manager pursuant to which the Manager provides Navios Partners administrative services; and (c) an omnibus agreement with Navios Holdings (“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. On January 1, 2012, in accordance with the terms of the partnership agreement, all of the outstanding subordinated units converted into 7,621,843 common units (conversion excluded the subordinated Series A units) and on June 29, 2012, in accordance with the terms of the partnership agreement, the outstanding subordinated Series A units converted into 1,000,000 common units. As of December 31, 2012, there were outstanding: 60,109,163 common units and 1,226,721 general partnership units. Navios Holdings owns a 25.2% interest in Navios Partners, which includes the 2% general partner interest.

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 (GAAP).

(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 as defined in the accounting guidance, if it determines that it is the primary beneficiary. A variable interest entity is defined as a legal entity where either (a) 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, (b) the equity holders have not provided sufficient equity investment to permit the entity to finance its activities without additional subordinated financial support, or (c) the voting rights of some investors are not proportional to their obligations to absorb the expected losses of the entity, their rights to receive the expected residual returns of the entity, or both and substantially all of the entity's activities either involve or are conducted on behalf of an investor that has disproportionately few voting rights.

Subsidiaries: 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 each subsidiary.

The accompanying consolidated financial statements include the following entities and chartered-in vessels:

(c)

Use of Estimates: The preparation of consolidated financial statements in conformity with the accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and 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 future drydock dates, the selection of useful lives for tangible assets, expected future cash flows from long-lived assets to support impairment tests, provisions necessary for accounts receivables, provisions for legal disputes, and contingencies. Management bases its estimates and judgments on historical experience and on various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from those estimates under different assumptions and/or conditions.

(d)

Cash and Cash equivalents: Cash and cash equivalents consist of cash on hand, deposits held on call with banks, and other short-term liquid investments with original maturities of three months or less.

(e)

Restricted Cash: Restricted cash includes an amount of $28,700 held in retention and pledged accounts as required by Navios Partners' credit facilities and an amount of $829 to guarantee a claim related to an owned vessel. As of December 31, 2012 and 2011 the restricted cash held in retention accounts was $29,529 and $8,468, 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, 2012 and 2011 was $458 and $49, respectively.

(g)

Insurance claims: Insurance claims consist of claims submitted and/or claims in the process of compilation or submission (claims pending against vessels' insurance underwriters). They are recorded on the accrual basis and represent the claimable expenses, net of applicable deductibles, incurred through December 31 of each reported period, which are expected to be recovered from insurance companies. Any remaining costs to complete the claims are included in accrued liabilities. The classification of insurance claims into current and non-current assets is based on management's expectations as to their collection dates. As provided in the management agreement, adjustments and negotiations of settlements of any claim damages which are recoverable under insurance policies are managed by the Manager. Navios Partners pays the deductible of any insurance claims relating to its vessels or for any claims that are within such deductible range.

(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 upgrading are capitalized, provided they appreciably extend the life, increase the earning capacity or improve the efficiency or safety of the vessels. 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 dry bulk vessels based on a scrap value of $285 per lightweight ton, as we believe these levels are common in the shipping industry. Management estimates the useful life of our vessels to be 25 years from the vessel's original construction. However, when regulations place limitations over the ability of a vessel to trade on a worldwide basis, its useful life is re-estimated to end at the date such regulations become effective.

(i)

Deferred Drydock and Special Survey costs: Navios Partners' vessels are subject to regularly scheduled dry docking and special surveys which are carried out every 30 or 60 months 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 costs of dry docking and special surveys are included in the daily management fee of $4.65 per owned Ultra-Handymax vessel, $4.55 per owned Panamax vessel and $5.65 per owned Capesize vessel through December 31, 2013. From January 2014 to December 2017, Navios Partners expects that it will reimburse the Manager for all of the actual operating costs and expenses it incurs in connection with the management of its fleet.

(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. In accordance with accounting for the “impairment or disposal of long-lived assets”, 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. 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 vessel and compared to the vessel carrying value of the vessel and related carrying value of the intangible with respect to the time charter agreement attached to that vessel. 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 2012, management concluded that events occurred and circumstances had changed, which indicated that potential impairment of Navios Partners' long-lived assets may exist. These indicators included continued deterioration in the spot market, and the related, impact of the current drybulk sector has on management's expectation for future revenues. As a result, an impairment assessment of long-lived assets was performed.

Navios Partners determined undiscounted projected net operating cash flows for each vessel and compared it to the vessel's carrying value together with the carrying value of the related intangible. The significant factors and assumptions used in the undiscounted projected net operating cash flow analysis included: determining the projected net operating cash flows by considering the charter revenues from existing time charters for the fixed fleet days (Navios Partners' remaining charter agreement rates) and an estimated daily time charter equivalent for the unfixed days (based on a combination of the Navios Partners' remaining charter agreement rates and the 10-year average historical one year time charter rates 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 2013 and thereafter assuming an annual increase of 3.0% and utilization rate of 98.6% based on the fleet's historical performance. The assessment concluded that step two of the impairment analysis was not required and no impairment of vessels and the intangible assets existed as of December 31, 2012, as the undiscounted projected net operating cash flows exceeded the carrying value.

In the event that impairment would occur, the fair value of the related asset would be determined and an impairment charge would be recorded to operations calculated by comparing the asset's carrying value to its fair value. Fair value is estimated primarily through the use of third-party valuations performed on an individual vessel basis.

Although management believes the underlying assumptions supporting this assessment are reasonable, if charter rate trends and the length of the current market downturn, vary significantly from our forecasts, management may be required to perform step two of the impairment analysis in the future that could expose Navios Partners to material impairment charges in the future.

No impairment loss was recognized for any of the periods presented.

(k)

Deferred Financing Cost: Deferred financing costs include fees, commissions and legal expenses associated with obtaining loan facilities. These costs are amortized over the life of the related debt using the effective interest rate method, and are included in interest expense. Amortization expense and write offs of deferred financing cost for each of the years ended December 31, 2012, 2011 and 2010 were: $787, $530 and $415, respectively.

(l)

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 statement of income in the depreciation and amortization line item. The amortizable value of favorable leases would be considered impaired if their fair market values could not be recovered from the future undiscounted cash flows associated with the asset. Vessel purchase options that have not been exercised, which are included in favorable lease terms, are not amortized and would be considered impaired if the carrying value of an option, when added to the option price of the vessel, exceeded the fair value of the vessel. If the purchase option is exercised the portion of this asset will be capitalized as part of the cost of the vessel and will be depreciated over the remaining useful life of the vessel. Management, after considering various indicators performed on impairment test which included intangible assets as described in paragraph (j) above. As of December 31, 2012, there was no impairment of intangible assets.

(m)

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 statement of operations. The foreign currency exchange (losses)/gains recognized in the accompanying consolidated statements of income, in other income or expense, for each of the years ended December 31, 2012, 2011 and 2010 were $(1), $(4) and $22, respectively.

(n)

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 and the likelihood of loss is deemed to be probable at the date of the financial statements and the amount of the loss can be reasonably estimated. In accordance with the accounting for contingencies, 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 to fund operating deficits incurred by the clubs (“deferred calls”). Obligations for deferred calls are accrued annually based on information provided by the clubs regarding supplementary calls. Services such as the ones described above are provided by the Manager under the management agreement and included as part of the daily fee of $4.55 for each Panamax vessel, $5.65 for each Capesize vessel and $4.65 for each Ultra-Handymax vessel through December 31, 2013.

(o)

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. 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.

(p)

Revenue and Expense Recognition:

Revenue 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.

Revenues from time chartering of vessels are accounted for as operating leases and are thus recognized on a straight line basis as the average minimum 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. Under time charters, operating costs such as for crews, maintenance and insurance are typically paid by the owner of the vessel.

Revenues from profit-sharing are calculated at an agreed percentage of the excess of the charterer's average daily income over an agreed amount and accounted for on an accrual basis based on provisional amounts.

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 rate. Since address commissions represent a discount (sales incentive) on services rendered by Navios Partners and no identifiable benefit is received in exchange for the consideration provided to the charterer, these commissions are presented as a reduction of revenue.

Time Charter Expenses: Time charter expenses comprise time charter hire, brokerage commissions, fuel costs and other miscellaneous expenses. Time charter expenses are expensed over the period of the time charter.

Management fees: Pursuant to the Management Agreement dated November 16, 2007, which was revised in October 2009 and 2011, 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) $4.65 daily rate per Ultra-Handymax vessel; (b) $4.55 daily rate per Panamax vessel; and (c) $5.65 daily rate per Capesize vessel until December 31, 2013.

These daily fees cover all of the vessels' operating expenses, including the cost of drydock and special surveys and are classified as management fees in the consolidated statements of income.

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, 2017.

Deferred Voyage Revenue: Deferred voyage revenue primarily relates to cash received from charterers prior to it being earned. These amounts are recognized as revenue over the voyage or charter period. In January 2009, Navios Partners and its counterparty to the Navios Hope charter party mutually agreed for a lump sum amount of approximately $30,443, of which Navios Partners received net of expenses in the amount of $29,589 in February 2009. Under a new charter agreement, the balance of the aggregate value of the original contract will be allocated to the period until its original expiration. The amount of $30,443 has been recognized as deferred revenue and amortized over the life of the vessel's contract.

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

(q)

Financial Instruments: Financial instruments carried on the balance sheet include cash and cash equivalents, restricted cash, accounts receivables and accounts 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, and 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 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. 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, 2012, Navios Partners' customers representing 10% or more of total revenue were Cosco Bulk Carrier Co. Ltd., Mitsui O.S.K. Lines, Ltd. and Samsun Logix, which accounted for 22.8%, 16.0% and 13.0%, respectively. For the year ended December 31, 2011, Cosco Bulk Carrier Co. Ltd., Mitsui O.S.K. Lines, Ltd. and Samsun Logix accounted for 22.2%, 18.5% and 13.2%, respectively, of total revenue. For the year ended December 31, 2010, Mitsui O.S.K. Lines, Ltd., Cargill International S.A. and Cosco Bulk Carrier Co. Ltd. accounted for 27.7%, 11.8% and 11.2%, respectively, of total revenue. No other customers accounted for 10% or more of total revenue for any of the years presented.

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 income.

(r)

Cash Distribution: As per the Partnership Agreement, within 45 days following the end of each quarter, 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.

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 at December 31, 2012 and 2011, Maintenance and Replacement capital expenditures reserve approved by the Board of Directors was $18,869 and $18,569, respectively.

Recent Accounting Pronouncements:

Fair Value Disclosures

In January 2010, the FASB issued amended standards requiring additional fair value disclosures. The amended standards require disclosures of transfers in and out of Levels 1 and 2 of the fair value hierarchy, as well as requiring gross basis disclosures for purchases, sales, issuances and settlements within the Level 3 reconciliation. Additionally, the update clarifies the requirement to determine the level of disaggregation for fair value measurement disclosures and to disclose valuation techniques and inputs used for both recurring and nonrecurring fair value measurements in either Level 2 or Level 3. Navios Partners adopted the new guidance in the first quarter of fiscal 2010, except for the disclosures related to purchases, sales, issuance and settlements, which was effective for Navios Partners beginning in the first quarter of fiscal 2012. The adoption of the new standards did not have a significant impact on Navios Partners' consolidated financial statements.

	$	160,479

On June 15, 2012, Navios Partners acquired from Navios Holdings, the Navios Buena Ventura for a purchase price of $67,500 of which $46,307 was allocated to the vessel and $21,193 allocated to the acquired time charter-out contract with favorable leases.

On May 19, 2011, Navios Partners purchased from Navios Holdings, the Navios Luz, a 2010 built Capesize vessel and the Navios Orbiter, a 2004 built Panamax vessel. Favorable lease terms recognized through this transaction amounted to $22,879 for the Navios Luz and $20,901 for the Navios Orbiter and were related to the acquisition of the rights on the time charter-out contracts of the vessels.

The Navios Apollon was off-hire due to an engine breakdown and therefore the charter-out contract was terminated. The net book value of the favorable lease term that was attached to the time charter-out contract was $3,979 and was written-off in the statement of income.

Intangible assets subject to amortization are amortized using straight line method over their estimated useful lives to their estimated residual value of zero. The weighted average useful lives are 7.7 years for favorable lease terms charter out.

Deferred Revenue [Abstract]
Deferred Voyage Revenue [Text Block]	NOTE 10 - DEFERRED VOYAGE REVENUE Deferred voyage revenue primarily reflects charter-out amounts collected on voyages that have not yet been completed. In addition, in January 2009, Navios Partners and its counterparty to the Navios Hope charter party mutually agreed for a lump sum amount of approximately $30,443, of which Navios Partners received net of expenses in the amount of $29,589 in February 2009. Under a new charter agreement, the balance of the aggregate value of the original contract is allocated to the period until its original expiration. The amount of $30,443 has been recognized as deferred revenue and amortized over the life of the vessel's contract in August 2013. As of December 31, 2012 and December 31, 2011, the deferred voyage revenue of $9,112 and $15,150, respectively, included the unamortized amount of the lump sum amount related to the Navios Hope of $4,230 and $10,991, respectively. As of December 31, 2012, the current and long-term portion of the lump sum amount was $4,230 and $0, respectively.

Total long term borrowings	$	275,982		$	289,350

As of December 31, 2012, all of our facilities were fully drawn and the total borrowings under the credit facilities amounted to $299,709. Navios Partners has no undrawn available facilities. Both facilities require compliance with certain financial covenants. As of December 31, 2012, Navios Partners was in compliance with the financial covenants of its credit facilities.

On July 31, 2012, Navios Partners entered into the July 2012 Credit Facility for $290,450. The July 2012 Credit Facility was entered into to refinance and merge Navios Partners' two existing facilities consisting of the Credit Facility, as amended, and the May 2011 Credit Facility. The July 2012 Credit Facility matures on November 30, 2017. In December 2012, Navios Partners amended the July 2012 Credit Facility to prepay $24,600. The prepayment will be applied in partial settlement of the next installments. As of December 31, 2012 the outstanding balance was $256,634 and is repayable in 20 installments in various amounts during the term of the July 2012 Credit Facility consisting of $5,006 (five quarterly installments), $6,967 (13 quarterly installments) and $11,829 (two quarterly installments) with a final payment of $117,375. The July 2012 Credit Facility bears interest at rates ranging from 180 to 205 bps per annum (depending on the loan amount compared to the security value) plus, depending on the length of the interest period, either LIBOR or the actual cost of funds. The refinancing of this facility was accounted for as debt modification in accordance with ASC470 Debt.

On August 8, 2012, Navios Partners entered into the August 2012 Credit Facility, and borrowed an amount of $44,000 to partially finance the acquisitions of the Navios Buena Ventura, the Navios Helios and the Navios Soleil. The August 2012 Credit Facility matures on February 9, 2018 and is repayable in 22 equal quarterly installments of $925 each with a final balloon payment of $23,650 to be repaid on the last repayment date. The August 2012 Credit Facility bears interest at a rate of LIBOR plus 350 bps.

Amounts drawn under the facilities are secured by first preferred mortgages on Navios Partners' vessels and other collateral and are guaranteed by each vessel-owning subsidiary. The credit facilities contain a number of restrictive covenants that prohibit or limit Navios Partners from, among other things: incurring or guaranteeing indebtedness; entering into affiliate transactions; charging, pledging or encumbering the vessels; changing the flag, class, management or ownership of Navios Partners' vessels; changing the commercial and technical management of Navios Partners' vessels; selling or changing the beneficial ownership or control of Navios Partners' vessels; and subordinating the obligations under the credit facilities to any general and administrative costs relating to the vessels, including the fixed daily fee payable under the management agreement. The credit facilities also require Navios Partners to comply with the ISM Code and ISPS Code and to maintain valid safety management certificates and documents of compliance at all times. The credit facilities also require compliance with a number of financial covenants of Navios Partners, including Net Worth, debt coverage ratios and minimum liquidity. It is an event of default under the loan facilities if such covenants are not complied with.

Fair Value Of Financial Instruments [Abstract]

FAIR VALUE OF FINANCIAL INSTRUMENTS [Text Block]

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: The carrying amounts reported in the consolidated balance sheets for interest bearing deposits approximate their fair value because of the short maturity of these investments.

Borrowings: The carrying amount of the floating rate loans approximates its fair value.

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


	December 31, 2012						December 31, 2011
	Book Value			Fair Value			Book Value			Fair Value
Cash and cash equivalents	$	32,132		$	32,132		$	48,078		$	48,078

Long-term debt	$	(299,709	)	$	(299,709	)	$	(326,050	)	$	(326,050	)

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 3 inputs as of December 31, 2012.

The number of the common units issued was calculated based on a price of $19.6883 per common unit, which was the NYSE volume weighted average trading price of the common units for the ten business days immediately prior to the acquisition.

SEGMENT INFORMATION [ABSTRACT]

SEGMENT INFORMATION [Text Block]

NOTE 14 - 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. 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. Dry bulk vessels operate worldwide. Revenues from specific geographic region which contribute over 10% of total revenue are disclosed separately.

Revenue by Geographic Region


	Year Ended December 31, 2012		Year Ended December 31, 2011		Year Ended December 31, 2010
Europe	$	29,658	$	24,436	$	26,067
Asia		151,608		147,642		99,442
North America		15,968		7,218		9,716
Australia		8,201		7,657		8,006

Total	$	205,435	$	186,953	$	143,231

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.

- Definition

Tabular disclosure of the profit or loss and total assets for each reportable segment. An entity discloses certain information on each reportable segment if the amounts (a) are included in the measure of segment profit or loss reviewed by the chief operating decision maker or (b) are otherwise regularly provided to the chief operating decision maker, even if not included in that measure of segment profit or loss.

Income Taxes	12 Months Ended
Income Taxes	Dec. 31, 2012
INCOME TAXES [ABSTRACT]
INCOME TAXES [Text Block]	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 income. As of January 1, 2013, foreign flagged vessels that are managed by Greek or foreign ship management companies in Greece are subject to Greek tonnage tax. The payment of tonnage tax exhausts the tax liability of the foreign ship owning company 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.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

NOTE 16 - COMMITMENTS AND CONTINGENCIES

Navios Partners is involved in various disputes and arbitration proceedings arising in the ordinary course of business. 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.

CASH DISTRIBUTION AND EARNINGS PER UNIT [Abstract]

CASH DISTRIBUTIONS AND EARNINGS PER UNIT [Text Block]

NOTE 19 - CASH DISTRIBUTIONS AND EARNINGS PER UNIT

The partnership agreement of Navios Partners requires that all available cash is distributed quarterly, after deducting expenses, including estimated maintenance and replacement capital expenditures and reserves. Distributions may be restricted by, among other things, the provisions of existing and future indebtedness, applicable partnership and limited liability company laws and other laws and regulations. The amount of the minimum quarterly distribution is $0.35 per unit or $1.40 unit per year and are made in the following manner, during the subordination period:

•

First, 98% to the holders of common units and 2% to the General Partner until each common unit has received a minimum quarterly distribution of $0.35 plus any arrearages from previous quarters;

•

Second, 98% to the holders of subordinated units and 2% to the General Partner until each subordinated unit has received a minimum quarterly distribution of $0.35; and

•

Third, 98% to all unitholders, pro rata, and 2% to General Partner, until each unit has received an aggregate amount of $0.4025

Thereafter 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 and Subordinated (1) Unitholders (2)			General Partner
Minimum Quarterly Distribution	$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	%

(1) As of January 1, 2012, all subordinated units, excluding subordinated Series A units, were converted into common units.
(2) As of June 29, 2012, all subordinated Series A units were converted into common units.

On January 24, 2012, the Board of Directors of Navios Partners authorized its quarterly cash distribution for the three month period ended December 31, 2011 of $0.44 per unit. The distribution was paid on February 14, 2012 to all holders of record of common and general partner units (not including holders of subordinated Series A units) on February 9, 2012. The aggregate amount of the declared distribution was $24,829.

On April 25, 2012, the Board of Directors of Navios Partners authorized its quarterly cash distribution for the three month period ended March 31, 2012 of $0.44 per unit. The distribution was paid on May 14, 2012 to all holders of record of common and general partner units (not including holders of subordinated Series A units) on May 10, 2012. The aggregate amount of the declared distribution was $26,923.

On July 23, 2012, the Board of Directors of Navios Partners authorized its quarterly cash distribution for the three month period ended June 30, 2012 of $0.4425 per unit. The distribution was paid on August 13, 2012 to all holders of record of common and general partner units on August 8, 2012. The aggregate amount of the declared distribution was $27,563.

On October 18, 2012, the Board of Directors of Navios Partners authorized its quarterly cash distribution for the three month period ended September 30, 2012 of $0.4425 per unit. The distribution was paid on November 13, 2012 to all holders of record of common and general partner units on November 8, 2012. The aggregate amount of the declared distribution was $27,563.

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. Basic earnings net income per unit is determined by dividing net income by the weighted average number of units outstanding during the period. Diluted earnings per unit is calculated in the same manner as net income per unit, except that the weighted average number of outstanding units increased to include the dilutive effect of outstanding unit options or phantom units. There were no options or phantom units outstanding during the years ended December 31, 2012, 2011 and 2010.

The General Partner's interest in net income is calculated as if all net income for the year was distributed according to the terms of Navios Partners partnership agreement, regardless of whether those earnings would or could be distributed. Navios Partners partnership agreement does not provide for the distribution of net income; rather, it provides for the distribution of available cash, which is a contractually defined term that generally means all cash on hand at the end of each quarter less the amount of cash reserves established by Navios Partners' board of directors to provide for the proper conduct of Navios Partners' business including reserves for maintenance and replacement capital expenditure and anticipated credit needs.

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

- Definition

Any certificate of deposit or savings account held by a bank or other financial institution for a short-term specified period of time. Because of their short-term, time deposits are considered highly liquid investments that are both readily convertible to known amounts of cash and so near their maturity that they present insignificant risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three-years ago does not become a cash equivalent when its remaining maturity is three months.

- Definition

This element represents the portion of the balance sheet assertion valued at fair value by the entity whether such amount is presented as a separate caption or as a parenthetical disclosure. Additionally, this element may be used in connection with the fair value disclosures required in the footnote disclosures to the financial statements. The element may be used in both the balance sheet and disclosure in the same submission. This item includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Company may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months.
