Description of Business	'
	NOTE 1 - DESCRIPTION OF BUSINESS

	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 Holdings, a vertically integrated seaborne shipping and logistics company with over 60 years of operating history in the drybulk shipping industry. 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% 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, 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 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.

	As of December 31, 2013, there were outstanding: 71,034,163 common units and 1,449,681 general partnership units. As of December 31, 2013, Navios Holdings owned a 21.6% interest in Navios Partners, which includes a 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:

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

(c) Equity method investments: 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.

Navios Partners evaluates its investments with equity method, for other than temporary impairment, on a quarterly basis. Consideration is given to (1) the length of time and the extent to which the fair value has been less than the carrying value, (2) the financial condition and near-term prospects and (3) the intent and ability of the Company to retain its investments for a period of time sufficient to allow for any anticipated recovery in fair value.

(d) 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.

(e) 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.

(f) Restricted Cash: Restricted cash includes an amount of $346 held in retention and pledged accounts as required by Navios Partners' credit facilities and an amount of $831 to guarantee a claim related to an owned vessel. As of December 31, 2013 and 2012, the restricted cash held in retention accounts was $1,177 and $29,529, respectively. Long-term restricted cash as of December 31, 2013 was $33,429 and related to amounts held in escrow, to partially finance a portion of the acquisition of vessels.

(g) 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, 2013 and 2012 was $613 and $458, respectively.

(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 drybulk 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. Prior to December 31, 2012, management estimated the residual values of its vessels based on a scrap rate of $285 per LWT. Effective January 1, 2013, following management's reassessment after considering current market trends for scrap rates and ten-year average historical scrap rates of the residual values of the Company's vessels, the estimated scrap value per LWT was increased to $340. This change in accounting estimate of scrap value did not materially affect the statement of income and the earnings per unit of the Company for the year ended December 31, 2013.

Management estimates the useful life of drybulk and container vessels to be 25 and 30 years, respectively, 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 36 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 was 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. In October 2013, Navios Partners amended its existing Management Agreement with the Manager, a subsidiary of Navios Holdings, to fix the fees for ship management services of its owned fleet at: (a) $4.00 daily rate per Ultra-Handymax vessel; (b) $4.10 daily rate per Panamax vessel; (c) $5.10 daily rate per Capesize vessel effective from January 1, 2014 through December 31, 2015; and (d) $6.50 daily rate per Post-Panamax container vessel effective from the delivery through December 31, 2015. Drydocking expenses under this agreement will be reimbursed by Navios Partners at cost at occurrence.

(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 2013, 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, 2013, 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 credit facilities. These costs are amortized over the life of the related facility 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, 2013, 2012 and 2011 were $4,035, $787 and $530, 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. Management, after considering various indicators, performed on impairment test which included intangible assets as described in paragraph (j) above. As of December 31, 2013, 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, 2013, 2012 and 2011 were $(13), $(1) and $(4), 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 (“additional calls”). Obligations for additional calls are accrued annually based on announcements made by the board of Directors of each Club at the end of each policy year pertaining to collection of any additional calls for the 'closed' policy year/s. . 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.

Voyage revenues for the transportation of cargo are recognized ratably over the estimated relative transit time of each voyage. Voyage expenses are recognized as incurred. A voyage is deemed to commence when a vessel is available for loading and is deemed to end upon the completion of the discharge of the current cargo. Estimated losses on voyages are provided for in full at the time such losses become evident. Under a voyage charter, a vessel is provided for the transportation of specific goods between specific ports in return for payment of an agreed upon freight per ton of cargo.

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 and Voyage Expenses: Time charter and voyage expenses comprise all expenses related to each particular voyage, including time charter hire paid and bunkers, port charges, canal tolls, cargo handling, agency fees and brokerage commissions. Time charter expenses are expensed over the period of the time charter and voyage expenses are recognized as incurred.

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.

In October 2013, Navios Partners amended its existing Management Agreement with the Manager, a subsidiary of Navios Holdings, to fix the fees for ship management services of its owned fleet at: (a) $4.00 daily rate per Ultra-Handymax vessel; (b) $4.10 daily rate per Panamax vessel; (c) $5.10 daily rate per Capesize vessel effective from January 1, 2014 through December 31, 2015; and (d) $6.50 daily rate per Post-Panamax container vessel effective from the delivery through December 31, 2015. Drydocking expenses under this agreement will be reimbursed 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, 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, an 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 through August 2013.

As of December 31, 2013 and December 31, 2012, the deferred voyage revenue of $2,997 and $9,112, respectively, included the unamortized amount of the lump sum amount related to the Navios Hope of $0 and $4,230, respectively. As of December 31, 2013, each of the current and long-term portion of the lump sum amount for the Navios Hope was zero.

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.

Inventory: Inventories, which are comprised of bunkers due to freight voyages, are valued at the lower of cost or market value as determined on the first-in, first-out basis.

(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 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, 2013, Navios Partners' customers representing 10% or more of total revenue were Cosco Bulk Carrier Co. Ltd., Hanjin Shipping Co. Ltd, Navios Corporation and Samsun Logix, which accounted for 23.4%, 11.3%, 10.4% and 10.2%, respectively. 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. 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, 2013, 2012 and 2011, Maintenance and Replacement capital expenditures reserve approved by the Board of Directors was $14,593, $18,869 and $18,569, respectively.

To date, for each of the vessels purchased from Navios Holdings, the vessel acquisition was effected through the acquisition of all of the capital stock of the vessel-owning companies, which held the ownership and other contractual rights and obligations related to each of the acquired vessels, including the vessel and a charter-out contract. Management accounted for each acquisition as an asset acquisition. At the transaction date, the purchase price approximated the fair value of the assets acquired, which was determined based on a combination of methodologies including discounted cash flow analyses and independent valuation analyses. The consideration paid, for each of these transactions, was allocated between the intangible assets (favorable lease term) and the vessel value.

In December 2013, Navios Partners acquired from an unrelated third party five 2006 South Korean-built Post-Panamax container vessels of 6,800 TEU each, consisting of the Hyundai Hongkong, the Hyundai Singapore, the Hyundai Tokyo, the Hyundai Shanghai and the Hyundai Busan for a total cash consideration of $275,000. Navios Partners allocated the total consideration to the fair value of the vessels, as these were the only assets acquired. There was no existing debt, charters or technical and commercial management agreements assumed, therefore, Navios Partners concluded that the acquisition of the Post-Panamax container vessels was an asset acquisition under ASC 805.

On October 11, 2013, Navios Partners acquired from an unrelated third party the Navios Harmony, an 82,790 dwt 2006 Japanese-built Panamax vessel, for an acquisition cost of $17,955 in cash consideration.

On September 11, 2013, Navios Partners acquired from an unrelated third party the Navios Joy, a 181,389 dwt Japanese new-build Capesize vessel, for an acquisition cost of $47,467 in cash consideration.

On July 27, 2012, Navios Partners acquired the Navios Helios from unrelated party, a 77,075 dwt Panamax vessel built in 2005, for an acquisition cost of $21,128 in cash consideration.

On July 24, 2012, Navios Partners acquired the Navios Soleil from unrelated party, a 57,337 dwt Ultra-Handymax vessel built in 2009, for an acquisition cost of $21,070 in cash consideration.

On June 15, 2012, Navios Partners acquired the Navios Buena Ventura from Navios Holdings 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.

Deposits for vessel acquisition represent deposits for vessels to be delivered in the future. As of December 31, 2013 and 2012, Navios Partners vessel deposits amounted to $7,271 and $0, respectively.

	The aggregate amortization of the intangibles for the 12-month periods ended December 31 is estimated to be as follows:


	Year	Amount
	2014	$ 26,442
	2015	21,169

	2019 and thereafter	19,824
		$ 119,405


	In relation to Navios Partners' new suspension agreement, entered into in June 2013, the amount of $3,205 of the Navios Melodia favorable lease term that corresponded to the suspension period until April 2016 has been accounted for accelerated amortization in the statement of income under the caption of Depreciation and amortization. The remaining favorable lease term intangible will continue to be amortized once the suspension period ends in April 2016.

	Intangible assets subject to amortization are amortized using the 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.

	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:

	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, 2013.

	NOTE 13 - 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. Drybulk and container vessels operate worldwide. Revenues from specific geographic region which contribute over 10% of total revenue are disclosed separately.

Income Taxes	'
	NOTE 14 - 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.

	NOTE 18 - INVESTMENT IN NAVIOS EUROPE INC.

	On October 9, 2013, Navios Holdings, Navios Acquisition and Navios Partners established Navios Europe and have ownership interests of 47.5%, 47.5% and 5.0%, respectively. On December 18, 2013, Navios Europe acquired ten vessels for aggregate consideration consisting of (i) cash consideration of $127,753 (which was funded with the proceeds of a $117,753 senior loan facility (the “Senior Loan”) and loans aggregating $10,000 from Navios Holdings, Navios Acquisition and Navios Partners (in each case, in proportion to their ownership interests in Navios Europe) (collectively, the “Navios Term Loans”) and (ii) the assumption of a junior participating loan facility (the “Junior Loan”) with a face amount of $173,367 and fair value of $71,929 as of December 31, 2013. In addition to the Navios Term Loans, Navios Holdings, Navios Acquisition and Navios Partners will also make available to Navios Europe (in each case, in proportion to their ownership interests in Navios Europe) revolving loans up to $24,100 to fund working capital requirements (collectively, the “Navios Revolving Loans”).

	On an ongoing basis, Navios Europe is required to distribute cash flows (after payment of operating expenses, amounts due pursuant to the terms of the Senior Loan and repayments of the Navios Revolving Loans) according to a defined waterfall calculation as follows:

	• First, Navios Holdings, Navios Acquisition and Navios Partners will each earn a 12.7% preferred distribution on the Navios Term Loans and the Navios Revolving Loans;

	• Second, any remaining cash is then distributed on an 80%/20% basis, respectively, between (i) the Junior Loan holder and (ii) the holders of the Navios Term Loans. The Navios Term Loan will be repaid from the future sale of vessels owned by Navios Europe and is deemed to be the initial investment by Navios Partners.

	Navios Partners evaluated its investment in Navios Europe under ASC 810 and concluded that Navios Europe is a VIE and that they are not the party most closely associated with Navios Europe and, accordingly, is not the primary beneficiary of Navios Europe based on the following:

	• the power to direct the activities that most significantly impact the economic performance of Navios Europe are shared jointly between (i) Navios Holdings, Navios Acquisition and Navios Partners and (ii) and the Junior Loan holder;

	• while Navios Europe's residual is shared on an 80%/20% basis, respectively, between (i) the Junior Loan holder and (ii) Navios Holdings, Navios Acquisition and Navios Partners, the Junior Loan holder is exposed to a substantial portion of Navios Europe's risks and rewards.

	Navios Partners further evaluated its investment in the common stock of Navios Europe under ASC 323 and concluded that it has the ability to exercise significant influence over the operating and financial policies of Navios Europe and, therefore, its investment in Navios Europe is accounted for under the equity method.

	As of December 31, 2013, the estimated maximum potential loss by Navios Partners in Navios Europe would have been $780, which represents the Company's portion of the initial investment of $500 plus the Company's portion of the carrying balance of the Navios Revolving Loans of $280 and does not include the undrawn portion of the revolving loans.

	For the year ended December 31, 2013, Navios Europe had minimal operations and therefore, the Company did not record any equity method investee income/(loss).

	As of December 31, 2013, the Navios Partners' portion of the Navios Revolving Loan was $ 280.Refer to Note 17 for the terms of the Navios Revolving Loans.

	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, 2013, 2012 and 2011.

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