Summary of Significant Accounting Policies	12 Months Ended
	Dec. 31, 2014
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 2: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	(a)      Basis of presentation: The accompanying consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP). Where necessary, comparative figures have been reclassified to conform to changes in presentation in the current year.
	The company has revised its classification of administrative fee revenue from affiliates to appropriately record such amounts as revenues in the statement of comprehensive (loss)/income.The impact of the revision, which management determined was not material to the financial statements, was to seperately present administrative fee revenue from affiliates of $7,868 and $5,994 in the year ended December 31, 2013 and 2012, respectively, and to separately present an equal amount related to general and administrative expenses incurred on behalf of affiliates.
	(b)      Principles of consolidation: The accompanying consolidated financial statements include the accounts of Navios Holdings, a Marshall Islands corporation, and both its majority and wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in the consolidated statements.
	The Company also consolidates entities that are determined to be variable interest entities (“VIE”) as defined in the accounting guidance, if the Company determines that it is the primary beneficiary. A VIE is defined as a legal entity where either (i) equity interest holders as a group lack the characteristics of a controlling financial interest, including decision making ability and an interest in the entity's residual risks and rewards, or (ii) the equity interest holders have not provided sufficient equity investment to permit the entity to finance its activities without additional subordinated financial support, or (iii) the voting rights of some investors are not proportional to their obligations to absorb the expected losses of the entity, their rights to receive the expected residual returns of the entity, or both and substantially all of the entity's activities either involve or are conducted on behalf of an investor that has disproportionately few voting rights.
	Subsidiaries: Subsidiaries are those entities in which the Company has an interest of more than one half of the voting rights or otherwise has power to govern the financial and operating policies of the entity. The acquisition method of accounting is used to account for the acquisition of subsidiaries. The cost of an acquisition is measured as the fair value of the assets given up, shares issued or liabilities undertaken at the date of acquisition. The excess of the cost of acquisition over the fair value of the net assets acquired and liabilities assumed is recorded as goodwill. All subsidiaries included in the consolidated financial statements are 100% owned, except for Navios Logistics, which is 63.8% owned by Navios Holdings and Navios Asia LLC (“Navios Asia”) and its wholly-owned subsidiaries, which were 51.0% owned by Navios Holdings, until May 2014, when Navios Holdings became the sole shareholder.
	Investments in Affiliates: Affiliates are entities over which the Company generally has between 20% and 50% of the voting rights, or over which the Company has significant influence, but it does not exercise control. Investments in these entities are accounted for under the equity method of accounting. Under this method the Company records an investment in the stock of an affiliate at cost, and adjusts the carrying amount for its share of the earnings or losses of the affiliate subsequent to the date of investment and reports the recognized earnings or losses in income. Dividends received from an affiliate reduce the carrying amount of the investment. The Company recognizes gains and losses in earnings for the issuance of shares by its affiliates, provided that the issuance of shares qualifies as a sale of shares. When the Company's share of losses in an affiliate equals or exceeds its interest in the affiliate, the Company does not recognize further losses, unless the Company has incurred obligations or made payments on behalf of the affiliate.
	Affiliates included in the financial statements accounted for under the equity method
	In the consolidated financial statements of Navios Holdings, the following entities are included as affiliates and are accounted for under the equity method for such periods: (i) Navios Partners and its subsidiaries (ownership interest as of December 31, 2014 was 20.0%, which includes a 2.0% general partner interest); (ii) Navios Acquisition and its subsidiaries (economic interest as of December 31, 2014 was 46.2%); (iii) Acropolis Chartering and Shipping Inc. (“Acropolis”) (economic interest as of December 31, 2014 was 35.0%); and (iv) Navios Europe and its subsidiaries (economic interest as of December 31, 2014 was 47.5%).

(c)      Use of Estimates: The preparation of consolidated financial statements in conformity with U.S.GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. On an on-going basis, management evaluates the estimates and judgments, including those related to uncompleted voyages, future drydock dates, the carrying value of investments in affiliates, the selection of useful lives for tangible assets, expected future cash flows from long-lived assets to support impairment tests, impairment test for goodwill provisions necessary for accounts receivables and demurrages, provisions for legal disputes, pension benefits, 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: As of December 31, 2014 and 2013, restricted cash included $1,974 and $1,451, respectively, which related to amounts held in a retention account in order to service debt and interest payments. Also included in restricted cash as of December 31, 2014 and 2013 are amounts held as security in the form of letters of guarantee or letters of credit totaling $590 for both reporting periods.
(f)      Insurance Claims: Insurance claims at each balance sheet date consist of claims submitted and/or claims in the process of compilation or submission (claims pending). They are recorded on an accrual basis and represent the claimable expenses, net of applicable deductibles, incurred through December 31 of each reporting period, which are probable 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.
(g)      Inventories: Inventories, which are comprised of lubricants, bunkers (when applicable) and stock provisions on board of the vessels, as well as petroleum products held by Navios Logistics, are valued at cost as determined on the first-in, first-out basis.
(h)      Vessels, Port Terminals, Tanker Vessels, Barges, Pushboats and Other Fixed Assets, net: Vessels, port terminals, tanker vessels, barges, pushboats and other fixed assets acquired as parts of business combinations are recorded at fair value on the date of acquisition and if acquired as an asset acquisition, are recorded at cost (including transaction costs). Vessels constructed by the company would be stated at historical cost, which consists of the contract price, capitalized interest and any material expenses incurred upon acquisition (improvements and delivery expenses). Subsequent expenditures for major improvements and upgrades are capitalized, provided they appreciably extend the life, increase the earnings capability or improve the efficiency or safety of the vessels. The cost and related accumulated depreciation of assets retired or sold are removed from the accounts at the time of sale or retirement and any gain or loss is included in the accompanying consolidated statements of comprehensive (loss)/income.
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, port terminals, tanker vessels, barges, push boats and other fixed assets, after considering the estimated residual value.
Annual depreciation rates used, which approximate the useful life of the assets are:
Vessels	25 years
Port terminals	5 to 40 years
Tanker vessels, barges and push boats	15 to 45 years
Furniture, fixtures and equipment	3 to 10 years
Computer equipment and software	5 years
Leasehold improvements	shorter of lease term or 6 years
Management estimates the residual values of the Company's dry bulk vessels based on a scrap value cost of steel times the weight of the ship noted in lightweight tons (“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 the depreciation expense in the period of the revision and future periods. Until December 31, 2012, management estimated the residual values of the Company's 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.
Management estimates the useful life of its vessels to be 25 years from the vessel's original construction. However, when regulations place limitations on the ability of a vessel to trade on a worldwide basis, its useful life is re-estimated to end at the date such regulations become effective. An increase in the useful life of a vessel or in its residual value would have the effect of decreasing the annual depreciation charge and extending it into later periods. A decrease in the useful life of a vessel or in its residual value would have the effect of increasing the annual depreciation charge.
(i)      Deposits for Vessels, Port Terminals and Other Fixed Assets: This represents amounts paid by the Company in accordance with the terms of the purchase agreements for the construction of vessels, port terminals and other long-lived fixed assets. Deposits for vessels, port terminals and other fixed assets also include pre-delivery expenses. Pre-delivery expenses represent any direct costs to bring the asset to the location and condition necessary for it to be capable of operating in the manner intended by management. Interest costs incurred during the construction (until the asset is substantially complete and ready for its intended use) are capitalized. Capitalized interest for the years ended December 31, 2014, 2013 and 2012 amounted to $2,334, $1,831 and $1,453, respectively.
(j)      Assets Held for Sale: It is the Company's policy to dispose of vessels and other fixed assets when suitable opportunities occur and not necessarily to keep them until the end of their useful life. The Company classifies assets and disposal groups as being held for sale when the following criteria are met: management has committed to a plan to sell the asset (disposal group); the asset (disposal group) is available for immediate sale in its present condition; an active program to locate a buyer and other actions required to complete the plan to sell the asset (disposal group) have been initiated; the sale of the asset (disposal group) is probable, and transfer of the asset (disposal group) is expected to qualify for recognition as a completed sale within one year; the asset (disposal group) is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. Long-lived assets or disposal groups classified as held for sale are measured at the lower of their carrying amount or fair value less cost to sell. These assets are not depreciated once they meet the criteria to be held for sale. No assets were classified as held for sale in any of the periods presented.
(k)      Impairment of Long Lived Assets: Vessels, other fixed assets and other long-lived assets held and used by Navios Holdings are reviewed periodically for potential impairment whenever events or changes in circumstances indicate that the carrying amount of a particular asset may not be fully recoverable. Navios Holdings' 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 asset group and compared to the carrying value of the vessel, the unamortized portion of deferred drydock and special survey costs related to the vessel, and the related carrying value of the intangible assets with respect to the time charter agreement attached to that vessel or the carrying value of deposits for newbuildings. Within the shipping industry, vessels are customarily bought and sold with a charter attached. The value of the charter may be favorable or unfavorable when comparing the charter rate to then-current market rates. The loss recognized either on impairment (or on disposition) will reflect the excess of carrying value over fair value (selling price) for the vessel asset group.
During the fourth quarter of fiscal year 2014, management concluded that events occurred and circumstances had changed, which indicated that potential impairment of Navios Holdings' long-lived assets might exist. These indicators included continued deterioration in the spot market, and the related impact of the current dry bulk sector has on management's expectation for future revenues. As a result, an impairment assessment of long-lived assets (step one) was performed.
The Company 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 deferred drydock and special survey costs related to the vessel and the carrying value of the related intangible assets. 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 (the Company's remaining charter agreement rates) and an estimated daily time charter equivalent for the unfixed days (based on 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 excluding days of scheduled off-hires, running cost based on current year actual, assuming an annual increase of 3.0% after 2016 and a utilization rate of 99.8% based on the fleet's historical performance.
For the deposits for new building vessels, the net cash flows also included the future cash out flows to make vessels ready for use, all remaining progress payments to shipyards and other pre-delivery expenses (e.g. capitalized interest).
The assessment concluded that step two of the impairment analysis was not required and no impairment of vessels, deposits for vessel acquisitions and the related intangible assets existed as of December 31, 2014 and 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 typically 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 the charter rate trends and the length of the market downturn, vary significantly from our forecasts, Navios Holdings may be exposed to material impairment charges in the future.
No impairment loss was recognized for any of the periods presented.
(l)      Deferred Drydock and Special Survey Costs: The Company's vessels, barges and push boats are subject to regularly scheduled drydocking and special surveys which are carried out every 30 and 60 months, respectively, for ocean-going vessels, and every 84 months for push boats and barges, 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 drydocking and special surveys are deferred and amortized over the above periods or to the next drydocking or special survey date if such date has been determined. Unamortized drydocking or special survey costs of vessels, barges and push boats sold are written-off to income in the year the vessel, barge or push boat is sold.
Costs capitalized as part of the drydocking or special survey consist principally of the actual costs incurred at the yard, and expenses relating to spare parts, paints, lubricants and services incurred solely during the drydocking or special survey period. For each of the years ended December 31, 2014, 2013 and 2012, the amortization of deferred drydockand special survey costs was $12,263, $9,581, and $7,289, respectively.
(m)      Deferred Financing Costs: Deferred financing costs include fees, commissions and legal expenses associated with obtaining or modifying 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 and write-off of deferred financing costs for each of the years ended December 31, 2014, 2013 and 2012 were $4,061, $5,384 and $6,309, respectively. See Note 17.
(n)      Goodwill and Other Intangibles
(i)         Goodwill: Goodwill is tested for impairment at the reporting unit level at least annually.
The Company evaluates impairment of goodwill using a two-step process. First, the aggregate fair value of the reporting unit is compared to its carrying amount, including goodwill (step one). The Company determines the fair value of the reporting unit based on discounted cash flow analysis and believes that the discounted cash flow analysis is the best indicator of fair value for its individual reporting units.
The fair value for goodwill impairment testing was estimated using the expected present value of future cash flows, using judgments and assumptions that management believes were appropriate in the circumstances. The significant factors and assumptions the Company used in its discounted cash flow analysis included: EBITDA, the discount rate used to calculate the present value of future cash flows and future capital expenditures. EBITDA assumptions included revenue assumptions, general and administrative expense growth assumptions, and direct vessel expense growth assumptions. The future cash flows from shipping operations were determined by considering the charter revenues from existing time charters for the fixed fleet days (the Company's remaining charter agreement rates) and an estimated daily time charter equivalent for the non-fixed days (based on a combination of one-year average historical charter rates and the 10-year average historical charter rates adjusted for outliers, as available for each type of vessel), which the Company believes is an objective approach for forecasting charter rates over an extended time period for long lived assets. The future cash flows from logistics operations were determined principally by combining revenues from existing contracts and estimated revenues based on the historical performance of the segment, including utilization rates and actual storage capacity.
If the fair value of a reporting unit exceeds the carrying amount, no impairment exists. If the carrying amount of the reporting unit exceeds the fair value, then the Company must perform the second step to determine the implied fair value of the reporting unit's goodwill and compare it with its carrying amount. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit to all the assets and liabilities of that reporting unit, as if the reporting unit had been acquired in a business combination and the fair value of the reporting unit was the purchase price. If the carrying amount of the goodwill exceeds the implied fair value, then goodwill impairment is recognized by writing the goodwill down to its implied fair value.
No impairment loss was recognized for any of the periods presented.
(ii)        Intangibles Other Than Goodwill: Navios Holdings' intangible assets and liabilities consist of favorable lease terms, unfavorable lease terms, customer relationships, trade name and port terminal operating rights. The fair value of the trade name was determined based on the “relief from royalty” method which values the trade name based on the estimated amount that a company would have to pay in an arm's length transaction to use that trade name. The asset is being amortized under the straight line method over 32 years. Navios Logistics' trade name is being amortized under the straight line method over 10 years.
The fair value of customer relationships was determined based on the “excess earnings” method, which relies upon the future cash flow generating ability of the asset. The asset is amortized under the straight line method.
Other intangibles that are being amortized, such as customer relationships and port terminal operating rights, would be considered impaired if their carrying value could not be recovered from the future undiscounted cash flows associated with the asset.
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 the Company to make significant assumptions and estimates of many variables including market charter rates, expected future charter rates, the level of utilization of the Company's vessels and the Company's 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 the Company's 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 consolidated statements of comprehensive (loss)/income in the “Depreciation and amortization” line item.
The amortizable value of favorable leases would be considered impaired if its fair market value 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. No impairment loss was recognized for any the periods presented.
Vessel purchase options that are included in favorable leases are not amortized and when the purchase option is exercised the asset is capitalized as part of the cost of the vessel and depreciated over the remaining useful life of the vessel and if not exercised, the intangible asset is written off. Vessel purchase options that are included in unfavorable lease terms are not amortized and when the purchase option is exercised by the charterer and the underlying vessel is sold, it will be recorded as part of gain/loss on sale of the assets. If the option is not exercised at the expiration date it is written-off in the consolidated statements of comprehensive (loss)/income.
The weighted average amortization periods for intangibles are:
Intangible assets/liabilities		Years
Trade name		21
Favorable lease terms		11.1
Unfavorable lease terms		9.4
Port terminal operating rights		32.5
Customer relationships		20.0-45.0
See also Note 7.
(o)      Foreign Currency Translation: The Company's functional and reporting currency is the U.S. dollar. The Company 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. The Company's subsidiaries in Uruguay, Argentina, Brazil and Paraguay transact a nominal amount of their operations in Uruguayan pesos, Argentinean pesos, Brazilian reales and Paraguayan guaranies whereas the Company's wholly-owned vessel subsidiaries and the vessel management subsidiaries transact a nominal amount of their operations in Euros; however, all of the subsidiaries' primary cash flows are U.S. dollar denominated. The financial statements of the foreign operations are translated using the exchange rate at the balance sheet date except for property and equipment and equity, which are translated at historical rates. Transactions in currencies other than the functional currency are translated at the exchange rate in effect at the date of each transaction. Differences in exchange rates during the period between the date a transaction denominated in a foreign currency is consummated and the date on which it is either settled or translated, are recognized in the statements of comprehensive (loss)/income. The foreign currency gains/(losses) recognized under the caption “Other income” and “Other expense”, respectively,  in the consolidated statements of comprehensive (loss)/income for each of the years ended December 31, 2014, 2013 and 2012, were $1,945, $184 and ($217), respectively.
(p)      Provisions: The Company, in the ordinary course of business, is subject to various claims, suits and complaints. Management, in consultation with internal and external advisers, will provide for a contingent loss in the financial statements if the contingency had occurred at the date of the financial statements and the likelihood of loss was probable and the amount can be reasonably estimated. If the Company has determined that the reasonable estimate of the loss is a range and there is no best estimate within the range, the Company will provide for the lower amount within the range. See Note 13, “Commitments and Contingencies” for further discussion.
The Company participates in Protection and Indemnity (P&I) insurance plans provided by mutual insurance associations known as P&I clubs. Under the terms of these plans, participants may be required to pay additional premiums (supplementary calls) to fund operating deficits incurred by the clubs (“back calls”). Obligations for back calls are accrued annually based on information provided by the P&I clubs.
Provisions for estimated losses on uncompleted voyages and vessels under time charter are provided for in the period in which such losses are determined. As of December 31, 2014 and 2013, the balance for provision for loss making voyages in progress was $1,893 and $801, respectively.
(q)      Segment Reporting: Operating segments, as defined, are components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. Based on the Company's methods of internal reporting and management structure, the Company currently has two reportable segments: the Dry Bulk Vessel Operations segment and the Logistics Business segment.
(r)      Revenue and Expense Recognition:
Revenue Recognition: Revenue is recorded when services are rendered, the Company has a signed charter agreement or other evidence of an arrangement, the price is fixed or determinable, and collection is reasonably assured. The Company generates revenue from transportation of cargo, time charter of vessels, port terminal operations, bareboat charters, contracts of affreightment/voyage contracts, demurrages and contracts covering dry or liquid port terminal operations.
Voyage revenues for the transportation of cargo are recognized ratably over the estimated relative transit time of each voyage. A voyage is deemed to commence when a vessel 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, the Company agrees to provide a vessel for the transportation of specific goods between specific ports in return for payment of an agreed upon freight rate per ton of cargo.
Revenues are recorded net of address commissions. Address commissions represent a discount provided directly to the charterers based on a fixed percentage of the agreed upon charter rate. Since address commissions represent a discount (sales incentive) on services rendered by the Company and no identifiable benefit is received in exchange for the consideration provided to the charterer, these commissions are presented as a reduction of revenue.
Revenue from time chartering and bareboat chartering is earned and recognized on a daily basis as the service is delivered. Revenue from contracts of affreightment(“COA”)/voyage contracts relating to our barges is recognized based upon the percentage of voyage completion. A voyage is deemed to commence upon the departure of the barge after discharge under the previous voyage and is deemed to end upon the completion of discharge under the current voyage. The percentage of voyage completion is based on the days traveled as of the balance sheet date divided by the total days expected for the voyage. The position of the barge at the balance sheet date is determined by the days traveled as of the balance sheet date over the total voyage of the pushboat having the barge in tow. Revenue arising from contracts that provide our customers with continuous access to convoy capacity is recognized ratably over the period of the contracts.
Demurrage income represents payments made by the charterer to the vessel owner when loading or discharging time exceeds the stipulated time in the voyage charter and is recognized as it is earned.
Revenues arising from contracts that provide our customers with continuous access to convoy capacity are recognized ratably over the period of the contracts.
Profit-sharing revenues are calculated at an agreed percentage of the excess of the charterer's average daily income (calculated on a quarterly or half-yearly basis) over an agreed amount and accounted for on an accrual basis based on provisional amounts and for those contracts that provisional accruals cannot be made due to the nature of the profit sharing elements, these are accounted for on the actual cash settlement.
Revenues from time chartering of vessels are accounted for as operating leases and are thus recognized on a straight line basis as the average revenue over the rental periods of such charter agreements as service is performed, except for loss generating time charters, in which case the loss is recognized in the period when such loss is determined. A time charter involves placing a vessel at the charterer's disposal for a period of time during which the charterer uses the vessel in return for the payment of a specified daily hire rate. Short period charters for less than three months are referred to as spot-charters. Charters extending three months to a year are generally referred to as medium-term charters. All other charters are considered long-term. Under time charters, operating costs such as for crews, maintenance and insurance are typically paid by the owner of the vessel.
Revenues from port terminal operations consist of an agreed flat fee per ton and cover the services performed to unload barges (or trucks), transfer the product into silos for temporary storage and then loading the ocean-going vessels. Revenues are recognized upon completion of loading the ocean-going vessels. Additionally, fees are charged for vessel dockage and for storage time in excess of contractually specified terms. Dockage revenues are recognized ratably up to completion of loading. Storage fees are assessed and recognized when the product remains in the silo storage beyond the contractually agreed time allowed. Storage fee revenue is recognized ratably over the storage period and ends when the product is loaded onto the ocean-going vessel.
Revenues from liquid port terminal operations consist mainly of sales of petroleum products in the Paraguayan market. Additionally, revenues consist of an agreed flat fee per cubic meter to cover the services performed to unload barges, transfer the products into the tanks for temporary storage and then loading the trucks. Revenues are recognized upon completion of loading the trucks. Additionally, fees are charged for storage time in excess of contractually specified terms. Storage fee revenue is recognized ratably over the storage period and ends when the product is loaded onto the trucks.
Recovery of lost revenue under credit default insurance for charterers is accounted for as gain contingency and is recognized when all contingencies are resolved. The amount of recovery of lost revenue is recorded within the caption “Revenue” and any amount recovered in excess of the lost revenue is recorded within the caption “Other income”.
Expenses related to our revenue-generating contracts are recognized as incurred.
Administrative fee revenue from affiliates: Administrative fee revenue from affiliates consists of fees earned on the provision of administrative services pursuant to administrative services agreements with our affiliates (Refer to Note 15). Administrative services 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 general and administrative services. These revenues are recognized as the services are provided to affiliates. The general and administrative expenses incurred on behalf of affiliates are determined based on a combination of actual expenses incurred on behalf of the affiliates as well as a reasonable allocation of expenses that are not affiliate specific but incurred on behalf of all affiliates.
Forward Freight Agreements (“FFAs”): Realized gains or losses from FFAs are recognized monthly concurrent with cash settlements. In addition, FFAs are “marked to market” quarterly to determine the fair values which generate unrealized gains or losses. Trading of FFAs could lead to material fluctuations in the Company's reported results from operations on a period to period basis. See Note 11.
Deferred Income and Cash Received In Advance: 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.
Time Charter, Voyage and Logistics Business Expenses: Time charter, voyage and logistics business expenses comprise all expenses related to each particular voyage, including time charter hire paid and voyage freight paid, bunkers, port charges, canal tolls, cargo handling, agency fees and brokerage commissions. Also included in time charter, voyage and logistics business expenses are charterers' liability insurances, provision for losses on time charters and voyages in progress at year-end, direct port terminal expenses and other miscellaneous expenses.
Direct Vessel Expenses: Direct vessel expenses consist of all expenses relating to the operation of vessels, including crewing, repairs and maintenance, insurance, stores and lubricants and miscellaneous expenses such as communications and amortization of drydocking and special survey costs net of related party management fees.
Prepaid Voyage Costs: Prepaid voyage costs relate to cash paid in advance for expenses associated with voyages. These amounts are recognized as expenses over the voyage or charter period.
(s)   Employee benefits:
Pension and Retirement Obligations-Crew: The Company's ship-owning subsidiaries employ the crew on board under short-term contracts (usually up to nine months) and, accordingly, they are not liable for any pension or post-retirement benefits.
Provision for Employees' Severance and Retirement Compensation: The employees in the Company's office in Greece are protected by Greek labor law. According to the law, the Company is required to pay retirement indemnities to employees upon dismissal or upon leaving with an entitlement to a full security retirement pension. The amount of compensation is based on the number of years of service and the amount of remuneration at the date of dismissal or retirement up to a maximum of two years' salary. If the employees remain in the employment of the Company until normal retirement age, they are entitled to retirement compensation which is equal to 40% of the compensation amount that would be payable if they were dismissed at that time. The number of employees that will remain with the Company until retirement age is not known. The Company considers this plan equivalent to a lump sum defined benefit pension plan and accounts for it under relevant guidance on employer's accounting for pensions. The Company is required to annually value the statutory terminations indemnities liability. Management obtains a valuation from independent actuaries to assist in the calculation of the benefits. The Company provides, in full, for the employees' termination indemnities liability. This liability amounted to $819 and $660 at December 31, 2014 and 2013, respectively.
U.S. Retirement Savings Plan: The Company sponsors a 401(k) retirement savings plan, which is categorized as a defined contribution plan. The plan is available to full time employees who meet the plan's eligibility requirements. The plan permits employees to make contributions up to 15% of their annual salary with the Company matching up to the first 6%. The Company makes monthly contributions (matching contributions) to the plan based on amounts contributed by employees. Subsequent to making the matching contributions, the Company has no further obligations. The Company may make an additional discretionary contribution annually if such a contribution is authorized by the Board of Directors. The plan is administered by an independent professional firm that specializes in providing such services. See Note 12.
Other Post-Retirement Obligations: The Company has a legacy pension arrangement for certain Bahamian, Uruguayan and former Navios Corporation employees. The entitlement to these benefits is only to these former employees. The expected costs of these benefits are accrued each year, using an accounting methodology similar to that for defined benefit pension plans. These obligations are valued annually by independent actuaries.
Stock-Based Compensation: In December 2014, 2013 and 2012, the Company authorized the issuance of shares of restricted common stock, restricted stock units and stock options in accordance with the Company's stock option plan for its employees, officers and directors. These awards of restricted common stock, restricted stock units and stock options are based on service conditions only and vest over three years. In December 2013 and 2014, the Company also authorized the issuance of shares of restricted common stock, restricted stock units and stock options for its employees, officers and directors that vest on April 30, 2015 and  June 2, 2016, respectively, upon achievement of certain internal performance criteria including certain targets on operational performance and cost efficiency. See Note 12.
The fair value of stock option grants is determined with reference to option pricing model and principally adjusted Black-Scholes models. The fair value of restricted stock and restricted stock units is determined by reference to the quoted stock price on the date of grant. Compensation expense, net of estimated forfeitures, is recognized based on a graded expense model over the vesting period. Compensation expense for the awards that vest upon achievement of the performance criteria is recognized when it is probable that the performance criteria will be met and are being accounted for as equity.
(t)      Financial Instruments: Financial instruments carried on the balance sheet include cash and cash equivalents, restricted cash, trade receivables and payables, other receivables and other liabilities, long-term debt, capital leases and available-for-sale securities. 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: The Company's activities expose it to a variety of financial risks including fluctuations in future freight rates, time charter hire rates, fuel prices and 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: The Company closely monitors its credit exposure to customers and counterparties for credit risk. The Company has policies in place to ensure that it trades with customers and counterparties with an appropriate credit history. Derivative counterparties and cash transactions are limited to high quality credit financial institutions.
Interest Rate Risk: Any differential to be paid or received on an interest rate swap agreement is recognized as a component of gain/loss on derivatives over the period of the agreement. Gains and losses on early termination of interest rate swaps are reflected in the consolidated statements of comprehensive (loss)/income. The effective portion of changes in the fair value of interest rate swap agreements that are designated and qualify as cash flow hedges are recognized in equity.
Liquidity Risk: Prudent liquidity risk management implies maintaining sufficient cash and marketable securities, the availability of funding through an adequate amount of committed credit facilities and the ability to close out market positions. The Company monitors cash balances appropriately to meet working capital needs.
Foreign Exchange Risk: Foreign currency transactions are translated into the measurement currency at rates prevailing on the dates of the relevant 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 comprehensive (loss)/income.
Accounting for Derivative Financial Instruments and Hedging Activities: The Company may enter into dry bulk shipping FFAs as economic hedges relating to identifiable ship and/or cargo positions and as economic hedges of transactions the Company expects to carry out in the normal course of its shipping business. By utilizing certain derivative instruments, including dry bulk shipping FFAs, the Company manages the financial risk associated with fluctuating market conditions. In entering into these contracts, the Company has assumed the risks that might arise from the possible inability of counterparties to perform in accordance with the terms of their contracts.
The Company also trades dry bulk shipping FFAs which are cleared through LCH, the London clearing house. LCH calls for both base and margin collateral, which are funded by Navios Holdings, and which in turn substantially eliminate counterparty risk. Certain portions of these collateral funds may be restricted at any given time as determined by LCH.
At the end of each calendar quarter, the fair value of dry bulk shipping FFAs traded over-the-counter are determined from an index published in London, United Kingdom and the fair value of those FFAs traded with LCH is determined from the LCH valuations.
The Company records all of its derivative financial instruments and hedges as economic hedges.
The Company classifies cash flows related to derivative financial instruments within cash provided by operating activities in the consolidated statements of cash flows.
(u)      (Loss)/Earnings Per Share: Basic (losses)/earnings per share are computed by dividing net (loss)/income attributable to Navios Holdings common stockholders by the weighted average number of shares of common stock outstanding during the periods presented. Diluted earnings per share reflect the potential dilution that would occur if securities or other contracts to issue common stock were exercised or converted. Dilution has been computed by the treasury stock method whereby all of the Company's dilutive securities (stock options and warrants) are assumed to be exercised and the proceeds are used to repurchase common shares at the weighted average market price of the Company's common stock during the relevant periods. The incremental shares (the difference between the number of shares assumed issued and the number of shares assumed purchased) are included in the denominator of the diluted earnings per share computation. Restricted stock and restricted stock units (vested and unvested) are included in the calculation of the diluted earnings per share, based on the weighted average number of restricted stock and restricted stock units assumed to be outstanding during the period. Convertible shares are included in the calculation of the diluted earnings per share, based on the weighted average number of convertible shares assumed to be outstanding during the period. See also Note 19.
(v)      Income Taxes: The Company is a Marshall Islands Corporation. Pursuant to various treaties and the United States Internal Revenue Code, the Company believes that substantially all its operations are exempt from income taxes in the Marshall Islands and the United States of America. The tax expense reflected in the Company's consolidated financial statements for the years ended December 31, 2014, 2013 and 2012 was mainly attributable to its subsidiaries in South America, which are subject to the Argentinean and Paraguayan income tax regimes.
The asset and liability method is used to account for future income taxes. Under this method, future income tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts and the tax bases of assets and liabilities. Future income tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on future income tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A deferred tax asset is recognized for temporary differences that will result in deductible amounts in future years. A valuation allowance is recognized if, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred tax asset will not be realized.
(w)      Dividends: Dividends are recorded in the Company's financial statements in the period in which they are declared. Navios Holdings paid $25,228, $24,710 and $30,730 to its common stockholders during the years ended December 31, 2014, 2013 and 2012, respectively, and $7,502, $1,695 and $1,705 to its preferred stockholders during the years ended December 31, 2014, 2013 and 2012, respectively.
(x)      Guarantees: A liability for the fair value of the obligation undertaken in issuing the guarantee is recognized. The recognition of fair value is not required for certain guarantees such as the parent's guarantee of a subsidiary's debt to a third party or guarantees on product warranties. For those guarantees excluded from the above guidance requiring the fair value recognition provision of the liability, financial statement disclosures of their terms are made.
On November 15, 2012, the Company agreed to provide Navios Partners with guarantees against counterparty default on certain existing charters (see also Notes 15 and 23).
(y)      Leases: Vessel leases where Navios Holdings is regarded as the lessor are classified as either finance leases or operating leases based on an assessment of the terms of the lease.
For charters classified as finance leases the minimum lease payments are recorded as the gross investment in the lease. The difference between the gross investment in the lease and the sum of the present values of the two components of the gross investment is recorded as unearned income which is amortized to income over the lease term as finance lease interest income to produce a constant periodic rate of return on the net investment in the lease.
For charters classified as operating leases where Navios Holdings is regarded as the lessor, refer to Note 2(r) “Revenue and Expense Recognition”.
For charters classified as operating leases where Navios Holdings is regarded as the lessee, the expense is recognized on a straight line basis over the rental periods of such charter agreements. The expense is included under the line item  “Time charter, voyage and logistics business expenses”.
(z)      Treasury Stock: Treasury stock is accounted for using the cost method. Excess of the purchase price of the treasury stock acquired, plus direct acquisition costs over its par value is recorded in additional paid-in capital.
(aa)      Trade Accounts Receivable: The amount shown as accounts receivable, trade, at each balance sheet date, includes receivables from charterers for hire, freight and demurrage billings and FFA counterparties, 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.
(ab)    Convertible Preferred Stock: The Company's 2% Mandatorily Convertible Preferred Stock (“Preferred Stock”) is recorded at fair market value on the date of issuance. The fair market value is determined using a binomial valuation model. The model which is used takes into account the credit spread of the Company, the volatility of its stock, as well as the price of its stock at the issuance date. Each preferred share has a par value of $0.0001. Each holder of Preferred Stock is entitled to receive an annual dividend equal to 2.0% on the nominal value of the Preferred Stock, payable quarterly, until such time as the Preferred Stock converts into common stock. Five years after the issuance date, 30.0% of the then-outstanding shares of Preferred Stock shall automatically convert into shares of common stock at a conversion price equal to $10.00 per share of common stock with the remaining balance of the then-outstanding shares of Preferred Stock being converted into shares of common stock under the same terms 10 years after their issuance date. At any time following the third anniversary from their issuance date, if the closing price of the common stock has been at least $20.00 per share, for 10 consecutive business days, the remaining balance of the then-outstanding preferred shares shall automatically convert at a conversion price equal to $14.00 per share of common stock. The holders of Preferred Stock are entitled, at their option, at any time following their issuance date and prior to their final conversion date, to convert all or any such then-outstanding preferred shares into common stock at a conversion price equal to $14.00 per common stock.
(ac)     Cumulative Redeemable Perpetual Preferred Stock: The Company's 2,000,000 American Depositary Shares, Series G Cumulative Redeemable Perpetual Preferred Stock (the “Series G”) and the 4,800,000 American Depositary Shares, Series H Cumulative Redeemable Perpetual Preferred Stock (the “Series H”) are recorded at fair market value on issuance. Each of the shares represents 1/100th of a share of the Series G, with a liquidation preference of $2,500.00 per share ($25.00 per American Depositary Share). Dividends are payable quarterly in arrears on the Series G at a rate of 8.75% per annum and on the Series H at a rate of 8.625% per annum of the stated liquidation preference. At any time on or after January 28, 2019, the Series G may be redeemed at the Company's option and at any time on or after July 8, 2019, the Series H may be redeemed at the Company's option (and the American Depositary Shares can be caused to be redeemed), in whole or in part, out of amounts legally available therefore, at a redemption price of $2,500.00 per share (equivalent to $25.00 per American Depositary Share) plus an amount equal to all accumulated and unpaid dividends thereon to the date of redemption, whether or not declared. The Company has accounted for these shares as equity.
(ad)      Investment in Available-for-Sale Securities: The Company classifies its existing marketable equity securities as available-for-sale. These securities are carried at fair value, with unrealized gains and losses excluded from earnings and reported directly in stockholders' equity as a component of other comprehensive (loss)/income unless an unrealized loss is considered “other-than-temporary,” in which case it is transferred to the consolidated statements of comprehensive (loss)/income. Management evaluates securities for other than temporary impairment (“OTTI”) on a quarterly basis. Consideration is given to (i) the length of time and the extent to which the fair value has been less than cost, (ii) the financial condition and near-term prospects of the investee, and (iii) the intent and ability of the Company to retain its investment in the investee for a period of time sufficient to allow for any anticipated recovery in fair value.
Investment in Equity Securities: Navios Holdings evaluates its investments in Navios Acquisition, Navios Partners and Navios Europe for OTTI on a quarterly basis. Consideration is given to (i) the length of time and the extent to which the fair value has been less than the carrying value, (ii) the financial condition and near-term prospects of Navios Partners, Navios Acquisition and Navios Europe, and (iii) the intent and ability of the Company to retain its investment in Navios Acquisition, Navios Partners and Navios Europe for a period of time sufficient to allow for any anticipated recovery in fair value.
(ae)      Financial Instruments and Fair Value: Guidance on Fair Value Measurements provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level I measurements) and the lowest priority to unobservable inputs (Level III measurements).
A financial instrument's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. In determining the appropriate levels, the Company performs a detailed analysis of the assets and liabilities that are subject to guidance on Fair Value Measurements.
(af)      Recent Accounting Pronouncements:
In April 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-08, “Presentation of Financial Statements and Property, Plant and Equipment”, changing the presentation of discontinued operations on the statements of income and other requirements for reporting discontinued operations. Under the new standard, a disposal of a component or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity's operations and financial results when the component meets the criteria to be classified as held-for-sale or is disposed. The amendments in this update also require additional disclosures about discontinued operations and disposal of an individually significant component of an entity that does not qualify for discontinued operations. The new accounting guidance is effective for interim and annual periods beginning after December 15, 2014. The adoption of the new standard is not expected to have a material impact on Navios Holdings' results of operations, financial position or cash flows.
In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers", changing the method used to determine the timing and requirements for revenue recognition on the statements of comprehensive income. Under the new standard, an entity must identify the performance obligations in a contract, the transaction price and allocate the price to specific performance obligations to recognize revenue when the obligation is completed. The amendments in this update also require disclosure of sufficient information to allow users to understand the nature, amount, timing and uncertainty of revenue and cash flow arising from contracts. The new accounting guidance is effective for interim and annual periods beginning after December 15, 2016. Early adoption is not permitted. The Company is currently reviewing the effect of ASU No. 2014-09 on its revenue recognition.
In January 2015, the FASB issued ASU No. 2015-01, “Income Statement-Extraordinary and Unusual Items”. This standard eliminates the concept of extraordinary and unusual items from U.S. GAAP. The new standard is effective for annual and interim periods after December 15, 2015. Early adoption is permitted. We plan to adopt this standard effective January 1, 2016. The adoption of this ASU is not expected to have a material impact on the Company's results of operations, financial position or cash flows.
In February 2015, the FASB issued ASU No. 2015-02, “Consolidation (Topic 810) - Amendments to the Consolidation Analysis”, which amends the criteria for determining which entities are considered VIEs, amends the criteria for determining if a service provider possesses a variable interest in a VIE and ends the deferral granted to investment companies for application of the VIE consolidation model. The ASU is effective for interim and annual periods beginning after December 15, 2015. Early application is permitted. We do not expect the adoption of this ASU to have a material impact on the  Company's results of operations, financial position or cash flows, except if Navios Holdings was to enter into new arrangements in 2015 that fall into the scope prior to adoption of this standard.

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

	Year ended December 31, 2014	$	(26,457	)	$	(792	)	$	8,785	$	(18,464	)
	During the year ended December 31, 2012, the increase in the Company's provision for losses on accounts receivable (which resulted from the recognition of $17,136 of bad debt expense during the period) relates mainly to (i) $4,593 of receivable balances from various defaulted charterers that are no longer covered by the Company's Charter Insurance following the Insurance Restructuring (each as defined in Note 23); and (ii) $12,543 of receivable balances from charterers whose financial condition and creditworthiness deteriorated during the period causing the Company to determine that these receivables may no longer be recoverable.
	Concentration of credit risk with respect to accounts receivable are limited due to the Company's large number of customers, who are internationally dispersed and have a variety of end markets in which they sell. Due to these factors, management believes that no additional credit risk beyond amounts provided for collection losses is inherent in the Company's trade receivables. For the year ended December 31, 2014, one customer accounted for 11.9% of the Company's revenue and for the years ended December 31, 2013 and 2012, none of the Company's customers accounted for more than 10% of the Company's revenue.

While it is anticipated that claims receivable will be recovered within one year, such claims may not all be recovered within one year due to the attendant process of settlement. Nonetheless, amounts are classified as current as they represent amounts currently due to the Company. All amounts are shown net of applicable deductibles.

INVESTMENTS IN AFFILIATES [Abstract]
INVESTMENTS IN AFFILIATES	NOTE 8: INVESTMENTS IN AFFILIATES
	Navios Partners
	On August 7, 2007, Navios Holdings formed Navios Partners under the laws of Marshall Islands. 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 2.0% general partner interest.
	On January 1, 2012, all of Navios Partners' outstanding subordinated units owned by Navios  Holdings converted into 7,621,843 common units of Navios Partners (excluding the Series A Subordinated Units, which are a separate class of subordinated units) (“the Conversion”). The Company concluded that the Conversion resulted in a change in the form of its investment in Navios Partners that was a reconsideration event pursuant to ASC 323-10-15-16a. In connection with that reconsideration, the Company concluded that the common units of Navios Partners, which prior to January 1, 2012 did not meet the definition of common stock or “in-substance common stock,” met the definition of “in-substance common stock” starting January 1, 2012. Although the common units continued to enjoy certain preferences by comparison to the Series A Subordinated Units, the Series A Subordinated Units constituted such a small portion of the capital structure of Navios Partners and, as such, the liquidation preference was not considered to be substantive under ASC 323-10-15-13a. In addition, at the time of the reconsideration, it was known that the Series A Subordinated Units would themselves automatically convert to common units of Navios Partners on June 29, 2012. Accordingly, the Company concluded that the risk and reward profile of the common units and Series A Subordinated Units were substantially the same in accordance with ASC 323-10-15-13b. As a result, the Company's entire investment in Navios Partners (a portion of which was previously accounted for as available-for-sale securities) is accounted for by the equity method from January 1, 2012. As a result, the carrying value of the available-for sale securities of $82,572 plus the amount reflected in other comprehensive losses of $6,158 (in each case, as of December 31, 2011) was reclassified to “Investments in Affiliates.”
	On June 29, 2012, the outstanding subordinated Series A units converted into 1,000,000 shares of common units which have the same distribution rights as all other common unit holders.
	In May 2012, Navios Partners completed its public offering of 4,600,000 common units. Navios Holdings paid $1,472 in order to retain its 2.0% general partner interest. Following this offering Navios Holdings' interest in Navios Partners decreased. The Company deemed that the issuance of shares qualified as a sale of shares by the equity method investee. As a result, a gain of $9,497 was recognized in “Equity in net earnings of affiliated companies” for the year ended December 31, 2012.
	In February and September 2013, Navios Partners completed two public offerings in an aggregate amount of 10,925,000 common units. Navios Holdings paid $3,168 in order to retain its 2.0% general partner interest. Following these offerings Navios Holdings' interest in Navios Partners decreased. The Company determined that the issuance of shares qualified as sales of shares by the equity method investee. As a result, gains of $15,991 were recognized in “Equity in net earnings of affiliated companies” for the year ended December 31, 2013.
	In February 2014, Navios Partners completed a public offering of 6,325,000 common units. Navios Holdings paid $2,233 in order to retain its 2.0% general partner interest. The Company determined, under the equity method, that the issuance of shares qualified as sales of shares by the investee. As a result, a gain of $11,230 was recognized in “Equity in net earnings of affiliated companies” for the year ended December 31, 2014.
	As of December 31, 2014, Navios Holdings holds a total of 14,223,763 common units and 1,578,763 general partners units, representing a 20.0% interest in Navios Partners, including the 2.0% general partner interest, and the entire investment in Navios Partners is accounted for under the equity method.
	As of December 31, 2014 and 2013, the unamortized difference between the carrying amount of the investment in Navios Partners and the amount of the Company's underlying equity in net assets of Navios Partners was $35,745 and $42,412, respectively. This difference is amortized through “Equity in net earnings of affiliated companies” over the remaining life of Navios Partners tangible and intangible assets.
	Total equity method income and amortization of deferred gain of $36,959, $39,738 and $48,946 were recognized in “Equity in net earnings of affiliated companies” for the years ended December 31, 2014, 2013 and 2012, respectively.
	As of December 31, 2014 and 2013, the carrying amount of the investment in Navios Partners was $114,387 and $110,516, respectively.
	Dividends received during the year ended December 31, 2014, 2013 and 2012 were $30,043, $29,461 and $27,916, respectively.
	As of December 31, 2014, the market value of the investment in Navios Partners was $155,181.
	Acropolis
	Navios Holdings has a 50% interest in Acropolis, a brokerage firm for freight and shipping charters. Although Navios Holdings owns 50% of Acropolis' stock, Navios Holdings agreed with the other shareholder that the earnings and amounts declared by way of dividends will be allocated 35% to the Company with the balance to the other shareholder. As of December 31, 2014 and 2013, the carrying amount of the investment was $525 and $350, respectively. Dividends received for each of the years ended December 31, 2014, 2013 and 2012 were $271, $433 and $140, respectively.
	Navios Acquisition
	In February, May and September 2013, Navios Acquisition completed multiple offerings, including registered direct offerings and private placements to Navios Holdings and certain members of the management of Navios Acquisition, Navios Partners and Navios Holdings. A total of 94,097,529 shares were issued. As part of these offerings, Navios Holdings purchased in private placements an aggregate of 46,969,669 shares of Navios Acquisition common stock for $160,001. The Company determined that the issuance of shares qualified as sales of shares by the equity method investee. As a result, losses of $6,171 were recognized in “Equity in net earnings of affiliated companies” for the year ended December 31, 2013.
	In February 2014, Navios Acquisition completed a public offering of 14,950,000 shares of its common stock. In October 2014, 699,994 Navios Acquisition's restricted stock awards vested. Following those events and as of December 31, 2014, Navios Holdings had a 43.1% voting and a 46.2% economic interest in Navios Acquisition. The Company determined, under the equity method, that the issuance of shares and the vesting of restricted stock awards qualified as a sale of shares by the investee. As a result, an income of $4,675 was recognized in “Equity in net earnings of affiliated companies” for the year ended December 31, 2014.

	Income of $831 was recognized in “Equity in net earnings of affiliated companies” for the year ended December 31, 2014 whilst 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).

Other indebtedness
In connection with the acquisition of Hidronave South American Logistics S.A. (“Hidronave”) on October 29, 2009, Navios Logistics assumed a $817 loan facility that was in 2001 in order to finance the construction of a pushboat (Nazira). As of December 31, 2014, the outstanding loan balance was $459. The loan facility bears interest at a fixed rate of 600 basis points. The loan is repayable in monthly installments of $6 each and the final repayment must occur prior to August 10, 2021. The loan also requires compliance with certain covenants.
During the year ended December 31, 2014, the Company paid $20,761 relating to scheduled repayment installments.
The annual weighted average interest rates of the Company's total borrowings were 7.18%, 7.75% and 7.32% for the year ended December 31, 2014, 2013 and 2012, respectively.
The maturity table below reflects the principal payments for the next five years and thereafter of all borrowings of Navios Holdings (including Navios Logistics) outstanding as of December 31, 2014, based on the repayment schedules of the respective loan facilities and the outstanding amount due under the debt securities.

FAIR VALUE OF FINANCIAL INSTRUMENTS [abstract]
FAIR VALUE OF FINANCIAL INSTRUMENTS	NOTE 11: FAIR VALUE OF FINANCIAL INSTRUMENTS
	Forward Freight Agreements (FFAs)
	Dry bulk shipping FFAs generally have the following characteristics: they cover periods from one month to one year; they can be based on time charter rates or freight rates on specific quoted routes; they are executed between two parties and give rise to a certain degree of credit risk depending on the counterparties involved and they are settled monthly based on publicly quoted indices.
	At December 31, 2014 and 2013, none of the “mark-to-market” positions of the open dry bulk FFA contracts, qualified for hedge accounting treatment. Dry bulk FFAs traded by the Company that do not qualify for hedge accounting are shown at fair value through the consolidated statements of comprehensive (loss)/income.
	The net losses from FFAs recorded in the consolidated statements of comprehensive (loss)/income amounted to $0, $260 and $196, for the years ended December 31, 2014, 2013 and 2012, respectively.
	During each of the years ended December 31, 2014, 2013 and 2012, the changes in net unrealized losses on FFAs amounted to $0, $(69) and $(124), respectively.
	Fair value of financial 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 and money market funds approximate their fair value because of the short maturity of these investments.
	Restricted cash: 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 their fair value. The 2019 Notes, the 2022 Notes, the 2019 and 2022 Logistics Senior Notes and the Navios Logistics loan are fixed rate borrowings and their fair value was determined based on quoted market prices.
	Capital leases: The capital leases are fixed rate obligations and their carrying amounts approximate their fair value.
	Loan receivable from affiliate companies: The carrying amount of the fixed rate loan approximates its fair value.
	Long-term receivable from affiliate companies: The carrying amount of the floating rate receivable approximates its fair value.
	Investments in available-for-sale securities: The carrying amount of the investments in available-for-sale securities reported in the consolidated balance sheets represents unrealized gains and losses on these securities, which are reflected directly in equity unless an unrealized loss is considered “other-than-temporary”, in which case it is transferred to the consolidated statements of comprehensive income/(loss).
	The estimated fair values of the Company's financial instruments were as follows:

EMPLOYEE BENEFIT PLANS [Abstract]
EMPLOYEE BENEFIT PLANS	NOTE 12: EMPLOYEE BENEFIT PLANS
	Retirement Saving Plan
	The Company sponsors an employee saving plan covering all of its employees in the United States. The Company's contributions to the employee saving plan during the years ended December 31, 2014, 2013 and 2012, were approximately $101, $97 and $119, respectively, which included a discretionary contribution of $17, $14, and $15, respectively.
	Defined Benefit Pension Plan
	The Company sponsors a legacy unfunded defined benefit pension plan that covers certain Bahamian and Uruguayan nationals and former Navios Corporation employees. The liability related to the plan is recognized based on actuarial valuations. The current portion of the liability is included in accrued expenses and the non-current portion of the liability is included in other long-term liabilities. There are no pension plan assets.
	The Greek office employees are protected by the Greek Labor Law. According to the law, the Company is required to pay retirement indemnities to employees on dismissal, or on leaving with an entitlement to a full security retirement pension. Please refer to Note 2(s).
	Stock Plan
	The Company has awarded shares of restricted stock and restricted stock units to its employees, officers and directors. The restriction lapses in two or three equal tranches, over the requisite service periods, of one, two and three years from the grant date. The Company has also awarded stock options to its officers and directors only, based on service conditions only, which vest in three equal tranches over the requisite service periods of one, two and three years from the grant date. Each option expires seven years after its grant date.
	On December 11, 2013, the Company awarded shares of restricted stock and restricted stock units to its employees, officers and directors and stock options to its officers and directors, which vest all at once upon achievement of the internal performance criteria and completion of a service period on April 30, 2015. As of December 31, 2014, the Company determined that it is probable that the performance criteria of these awards would be met and recognized a compensation expense of $3,753.
	On December 15, 2014, the Company awarded shares of restricted stock and restricted stock units to its employees, officers and directors and stock options to its officers and directors, which vest all at once upon achievement of the internal performance criteria and completion of a service period on June 2, 2016.
	The fair value of all stock option awards has been calculated based on the modified Black-Scholes method. A description of the significant assumptions used to estimate the fair value of the stock option awards is set out below:
	Expected term: The Company began granting stock options in October 2007. The first stock option exercise was in 2010 and the number of options exercised during each of the years ended December 31, 2014 (143,189), 2013 (153,556), 2012 (29,251), 2011 (130,578) and 2010 (130,577) was small in relation to the total number of options granted. Therefore, due to limited historical share option exercise experience to provide for a reasonable basis upon which to estimate expected term, the Company opted to apply the simplified method.
	The “simplified method” used includes taking the average of the weighted average time to vesting and the contractual term of the option award. The service conditions option awards vest over three years at 33.3%, 33.3% and 33.4% respectively, resulting in a weighted average time to vest of approximately 2 years. The contractual term of the award is 7 years. Utilizing the simplified approach formula, the derived expected term estimate for the Company's service conditions option award is 4.5 years.
	Expected volatility: The historical volatility of Navios Holdings' shares was used in order to estimate the volatility of the stock option awards. The final expected volatility estimate, which equals the historical estimate, for the service conditions option awards is 47.06%, 42.62% and 43.87% for 2014, 2013 and 2012, respectively, and for the performance conditions option awards is 58.78% and 41.48%  for 2014 and 2013, respectively.
	Expected dividends: The expected dividend is based on the current dividend, our historical pattern of dividend increases and the market price of our stock.
	Risk-free rate: Navios Holdings has selected to employ the risk-free yield-to-maturity rate to match the expected term estimated under the “simplified method”. For the service conditions option awards, the 4.5 year yield-to-maturity rate as of the grant date is 1.44%, 1.28% and 0.68% for 2014, 2013 and 2012, respectively. For the performance conditions option awards, the one year yield-to-maturity rate as of the grant date is 0.22% and 0.13% for 2014 and 2013, respectively.
	The fair value of restricted stock and restricted stock unit grants excludes dividends to which holders of restricted stock and restricted stock units are not entitled. The expected dividend assumption used in the valuation of restricted stock and restricted stock units grant is $0.06 for 2014, 2013 and 2012.
	The weighted average grant date fair value of stock options, restricted stock and restricted stock units granted during the year ended December 31, 2014 was $1.14, $3.64 and $3.64, respectively.
	The weighted average grant date fair value of stock options, restricted stock and restricted stock units granted during the year ended December 31, 2013 was $2.11, $8.63 and $8.63, respectively.
	The weighted average grant date fair value of stock options, restricted stock and restricted stock units granted during the year ended December 31, 2012 was $0.84, $3.44 and $3.44, respectively.
	The effect of compensation expense arising from the stock-based arrangements described above amounted to $7,719, $5,021 and $4,712 for the years ended December 31, 2014, 2013 and 2012, respectively and it was reflected in general and administrative expenses on the consolidated statements of comprehensive (loss)/income. The recognized compensation expense for the year is presented as adjustment to reconcile net income to net cash provided by operating activities on the consolidated statements of cash flows.
	The summary of stock-based awards is summarized as follows (in thousands except share and per share data):

COMMITMENTS AND CONTINGENCIES [Abstract]
COMMITMENTS AND CONTINGENCIES	NOTE 13: COMMITMENTS AND CONTINGENCIES
	As of December 31, 2014, the Company was contingently liable for letters of guarantee and letters of credit amounting to $590 (December 31, 2013: $590) issued by various banks in favor of various organizations and the total amount was collateralized by cash deposits, which were included as a component of restricted cash.
	In connection with the acquisition of Horamar on January 1, 2008, Navios Logistics recorded liabilities for certain pre-acquisition contingencies that were included in the allocation of the purchase price based on their respective fair values. As it relates to these contingencies, the prior owners of Horamar agreed to indemnify Navios Logistics in the event that any of the above contingencies materialize before agreed-upon dates, extending to various dates by 2021. As of December 31, 2014, the remaining liability related to these pre-acquisition contingencies amounted to $81 (December 31, 2013: $829) and was entirely offset by an indemnification asset for the same amount, which was reflected in other long-term assets.
	Navios Logistics has issued a guarantee and indemnity letter that guarantees the performance by Petrolera San Antonio S.A. of all its obligations to Vitol S.A. up to $12,000. This guarantee expires on March 1, 2016.
	The Company 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 the Company believes that a liability may be probable, and for which the amounts can be reasonably estimated, based upon facts known on the date the financial statements were prepared. Although the Company cannot predict with certainty the ultimate resolutions of these matters, in the opinion of management, the ultimate disposition of these matters is not expected to have a material adverse effect on the Company's financial position, results of operations or liquidity.
	The Company, in the normal course of business, entered into contracts to time charter-in vessels for various periods through April 2026.
	As of December 31, 2014, the Company had future remaining contractual deposits for two newbuilding owned vessels, which are expected to be delivered in the third and fourth quarter of 2015. Navios Logistics had obligations related to the acquisition of three new pushboats, the payment of the deferred considerations for the acquisition of two companies, who hold the right to occupy approximately 53 acres of land located in the Nueva Palmira free zone in Uruguay and the remaining installments for the acquisition of the chartered-in fleet consisting of one pushboat and three liquid barges of $15,996, $6,800 and $7,510, respectively.

(LOSS)/EARNINGS PER COMMON SHARE	NOTE 19: (LOSS)/EARNINGS PER COMMON SHARE
	(Loss)/earnings per share are calculated by dividing net (loss)/income by the weighted average number of shares of Navios Holdings outstanding during the period.
	For the year ended December 31, 2014, 3,437,148 potential common shares and 7,950,425 potential shares of convertible preferred stock have an anti-dilutive effect (i.e. those that increase income per share or decrease loss per share) and are therefore excluded from the calculation of diluted net loss per share.
	For the year ended December 31, 2013, 2,649,796 potential common shares and 8,479,000 potential shares of convertible preferred stock have an anti-dilutive effect (i.e. those that increase income per share or decrease loss per share), and are therefore excluded from the calculation of diluted net loss per share.

INCOME TAXES [Abstract]
INCOME TAXES	NOTE 20: INCOME TAXES
	Marshall Islands, Greece, Liberia, Panama and Malta, do not impose a tax on international shipping income. Under the laws of Marshall Islands, Greece, Malta, Liberia and Panama the countries of  incorporation of the Company and its subsidiaries and the vessels' registration, the companies are subject to registration and tonnage taxes which have been included in direct vessel expenses in the accompanying consolidated statements of comprehensive (loss)/income.
	Certain of the Company's subsidiaries are registered as Law 89 companies in Greece. These Law 89 companies are exempt from Greek income tax on their income derived from certain activities related to shipping. Since all the Law 89 companies conduct only business activities that qualify for the exemption of Greek income tax, no provision has been made for Greek income tax with respect to income derived by these Law 89 companies from their business operations in Greece.
	In accordance with the currently applicable Greek law, foreign flagged vessels that are managed by Greek or foreign ship management companies having established an office in Greece are subject to duties towards the Greek state which are calculated on the basis of the relevant vessel's tonnage. The payment of said duties exhausts the tax liability of the foreign ship owning company and the relevant manager against any tax, duty, charge or contribution payable on income from the exploitation of the foreign flagged vessel.
	Additionally, under a new tax bill ratified on January 14, 2013, an annual contribution, applying only to fiscal years 2012-2015, was imposed on offices or branches of foreign enterprises that have been established in Greece and are engaged in the exploitation, chartering, insurance, average (damage) settlements, purchase, chartering or shipbuilding brokerage, or chartering or insurance of ships under Greek or foreign flag, as well as the representation of ship-owner companies or undertakings, whose object is identical to the abovementioned activities. This contribution is imposed on the total amount of imported foreign exchange, calculated on a minimum $50.
	In Belgium, profit from ocean shipping is taxable based on the tonnage of the sea-going vessels from which the profit is obtained (“tonnage tax”).
	Pursuant to Section 883 of the Internal Revenue Code of the United States (the “Code”), U.S. source income from the international operation of ships is generally exempt from U.S. income tax if the company that is treated for U.S. federal income tax purposes as earning such income meets certain requirements set forth in Section 883 of the Code and the U.S. Treasury regulations thereunder. Among other things, in order to qualify for this exemption, each relevant company must be incorporated in a country which grants an “equivalent exemption” from income taxes to U.S. corporations. In addition, either (i) the stock of each relevant company must be treated under Section 883 of the Code and the U.S. Treasury regulations thereunder as “primarily traded” and “regularly traded” on an “established securities market” in the United States or in another country that grants an “equivalent exemption” or (ii) more than 50% of the value of the stock of each relevant company must be owned, directly or indirectly, by (a) individuals who are residents in countries that grant an “equivalent exemption,” (b) foreign corporations organized in countries that grant an “equivalent exemption” and that meet the test described in (i) and/or (c) certain other shareholders described in Section 883 of the Code and the U.S. Treasury regulations thereunder. The management of the Company believes that the Company and each of its relevant subsidiaries qualifies for the tax exemption under Section 883 of the Code, provided that the Company's common stock represents more than 50% of the total combined voting power of classes of the Company's stock entitled to vote and of the total value of the Company's stock, and less than 50% of the Company's common stock is owned, actually or constructively under specified stock attribution rules, on more than half the number of days in the relevant year by persons who each own more 5% or more of the vote and value of the Company's common stock, but no assurance can be given that this will remain so in the future.
	The tax expense reflected in the Company's consolidated financial statements for the years ended December 31, 2014, 2013 and 2012 is mainly attributable to Navios Holdings' subsidiaries in South America, which are subject to the Argentinean, Brazilian and Paraguayan income tax regime.
	CNSA is located in a tax free zone and is not liable to income or other tax. Navios Logistics' operations in Uruguay are exempted from income taxes.
	Income tax liabilities of the Argentinean companies for the current and prior periods are measured at the amount expected to be paid to the taxation authorities, using a tax rate of 35% on the taxable net income. Tax rates and tax laws used to assess the income tax liability are those that are effective on the close of the fiscal period. Additionally, at the end of the fiscal year, local companies in Argentina have to calculate an assets tax (“Impuesto a la Ganancia Minima Presunta” or Alternative Minimum Tax). This tax is supplementary to income tax and is calculated by applying the effective tax rate of 1% over the gross value of the corporate assets (based on tax law criteria). The subsidiaries' tax liabilities will be the higher of income tax or Alternative Minimum Tax. However, if the Alternative Minimum Tax exceeds income tax during any fiscal year, such excess may be computed as a prepayment of any income tax excess over the Alternative Minimum Tax that may arise in the next ten fiscal years.
	Under the tax laws of Argentina, the subsidiaries of the Company in that country are subject to taxes levied on gross revenues. Rates differ depending on the jurisdiction where revenues are earned for tax purposes. Average rates were approximately 5.0% for the year ended December 31, 2014 (4.9% and 4.7%  for 2013 and 2012, respectively).
	There are two possible options to determine the income tax liability of Paraguayan companies. Under the first option income tax liabilities for the current and prior periods are measured at the amount expected to be paid to the taxation authorities, by applying the tax rate of 10% on the fiscal profit and loss. 50% of revenues derived from international freights are considered Paraguayan sourced (and therefore taxed) if carried between Paraguay and Argentina, Bolivia, Brazil or Uruguay. Alternatively, only 30% of revenues derived from international freights are considered Paraguayan sourced. Companies whose operations are considered international freights can choose to pay income taxes on their revenues at an effective tax rate of 1% on such revenues, without considering any other kind of adjustments. Fiscal losses, if any, are neither deducted nor carried forward.
	The corporate income tax rate in Brazil and Paraguay is 34% and 10%, respectively, for the year ended December 31, 2014.
	During the year ended December 31, 2013, Navios Logistics decided to merge certain subsidiaries in Paraguay. As a result of the merger, Navios Logistics distributed specifically identified earnings, which were offset by retained net losses of $43,475. Navios Logistics' decision to merge the subsidiaries resulted in a one-off income tax benefit in deferred income tax of $4,333 in 2013.
	The Company's deferred taxes as of December 31, 2014 and 2013, relate primarily to deferred tax liabilities on acquired intangible assets recognized in connection with the Horamar acquisition.
	As of January 1, 2007, the Company adopted the provisions of FASB for Accounting for Uncertainty in Income Taxes. This guidance requires application of a more likely than not threshold to the recognition and derecognition of uncertain tax positions. This guidance permits the Company to recognize the amount of tax benefit that has a greater that 50% likelihood of being ultimately realized upon settlement. It further requires that a change in judgment related to the expected ultimate resolution of uncertain tax positions be recognized in earnings in the quarter of such change. Kleimar's open tax years are 2007 and onwards. Argentinean companies have open tax years ranging from 2007 and onwards and Paraguayan and Brazilian companies have open tax years ranging from 2008 and onwards. In relation to these open tax years, the Company believes that there are no material uncertain tax positions.

	On January 1, 2012, all of Navios Partners' outstanding subordinated units owned by Navios Holdings converted into 7,621,843 common units of Navios Partners (excluding the Series A subordinated units, which are a separate class of subordinated units). As a result, the Company's entire investment in Navios Partners (a portion of which was previously accounted for as available-for-sale securities) is accounted for by the equity method from January 1, 2012.
	During the years ended December 31, 2013 and 2012, the Company received shares of Korea Line Corporation (“KLC”) as partial compensation for the claims filed under the Korean court for all unpaid amounts by KLC in respect of the employment of the vessels. The shares were valued at fair value upon the day of issuance. As of both December 31, 2014 and 2013, the Company retained a total of 314,077 KLC shares.
	The shares received from KLC were accounted for under the guidance for available-for-sale securities (the “AFS Securities”). The Company has no other types of available-for-sale securities.
	As of December 31, 2014 and 2013, the carrying amount of the available-for-sale securities related to KLC was $6,701 and $7,660, respectively. The unrealized holding losses related to these AFS Securities included in “Accumulated other comprehensive loss” were $578, $11,172 and $558 as of December 31, 2014, 2013 and 2012, respectively. As of June 30, 2014, the Company considered the decline in fair value of the KLC shares as “other-than-temporary” and therefore, recognized a loss out of accumulated other comprehensive (loss)/income of $11,553. The respective loss was included within the caption “Other expense” in the accompanying consolidated statement of comprehensive (loss)/income. There were no OTTI losses during the years ended December 31, 2013 and 2012.

OTHER INCOME- OTHER EXPENSE	NOTE 23: OTHER INCOME - OTHER EXPENSE
	On November 15, 2012, Navios Holdings agreed with its credit default insurer to restructure its existing insurance policy (the “Charter Insurance”) with respect to counterparty defaults pursuant to certain charter agreements (the “Insurance Restructuring”). In connection with the Insurance Restructuring, Navios Holdings received a one-time upfront cash payment equal to $175,433 and agreed to maintain certain long-term charters under the Charter Insurance. Contemporaneously, the Company entered into an agreement with Navios Partners that provided Navios Partners with guarantees against counterparty default (up to $20,000) on certain existing charters (the “Navios Partners Guarantee”) (see also Note 15). The one-time upfront cash payment was accounted for as follows:
	$168,013 of the proceeds, which represented the irrevocable/non-refundable portion of the total proceeds, were recorded immediately in the statements of comprehensive (loss)/income within the caption “Other income”; and
	$7,420 of the proceeds, which represents reimbursements for insurance claims submitted for the period prior to the date of the restructuring, were recorded immediately in the statements of comprehensive (loss)/income within the caption “Revenue.”
	Following consummation of the Insurance Restructuring, the Company also reversed to income (“Other income” within the statements of comprehensive (loss)/income) an amount equal to $21,592 recorded on the Company's balance sheet as a liability (“cash received in advance”) related to an on-going claim. In connection with the Insurance Restructuring, these amounts also became irrevocable/non-refundable.
	During the year ended December 31, 2013, the Company received shares of KLC as discussed in Note 22 above, which were valued at fair value upon the day of issuance. As a result of the valuation of the KLC shares and settlement in full of KLC's claims, the Company also recorded income of $14,995 in the statement of comprehensive (loss)/income within the caption “Other income”.
	As of March 25, 2014, the Company terminated the amended credit default insurance policy. In connection with the termination, Navios Holdings received compensation of $4,044. From the total compensation, $3,551 was recorded immediately in the statement of other comprehensive (loss)/income within the caption "Other income" and the remaining amount within the caption “Revenue”, representing reimbursements for insurance claims submitted for the period prior to the date of the termination of the credit default insurance policy. The Company has no future requirement to repay any of the lump sum cash payment back to the insurance company or provide any further services.
	In May 2014, Navios Holdings received cash compensation of $7,203 from the sale of a defaulted counterparty claim to an unrelated third party. Navios Holdings has no continuing obligation to provide any further services to the counterparty or any further recourse or obligation to the third party to which it sold the claim and has therefore recognized the entire compensation received immediately in the statement of comprehensive (loss)/income within the caption of “Other income”.
	During the years ended December 31, 2014, 2013 and 2012, taxes other than income taxes of Navios Logistics amounted to $9,275, $7,912 and $8,212, respectively, and were included in the statements of comprehensive (loss)/income within the caption “Other expense”.

Summary of Significant Accounting Policies (Policies)	12 Months Ended

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]
Basis of presentation
	(a)      Basis of presentation: The accompanying consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP). Where necessary, comparative figures have been reclassified to conform to changes in presentation in the current year.
	The company has revised its classification of administrative fee revenue from affiliates to appropriately record such amounts as revenues in the statement of comprehensive (loss)/income.The impact of the revision, which management determined was not material to the financial statements, was to seperately present administrative fee revenue from affiliates of $7,868 and $5,994 in the year ended December 31, 2013 and 2012, respectively, and to separately present an equal amount related to general and administrative expenses incurred on behalf of affiliates.
Principles of Consolidation	(b)      Principles of consolidation: The accompanying consolidated financial statements include the accounts of Navios Holdings, a Marshall Islands corporation, and both its majority and wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in the consolidated statements.
	The Company also consolidates entities that are determined to be variable interest entities (“VIE”) as defined in the accounting guidance, if the Company determines that it is the primary beneficiary. A VIE is defined as a legal entity where either (i) equity interest holders as a group lack the characteristics of a controlling financial interest, including decision making ability and an interest in the entity's residual risks and rewards, or (ii) the equity interest holders have not provided sufficient equity investment to permit the entity to finance its activities without additional subordinated financial support, or (iii) the voting rights of some investors are not proportional to their obligations to absorb the expected losses of the entity, their rights to receive the expected residual returns of the entity, or both and substantially all of the entity's activities either involve or are conducted on behalf of an investor that has disproportionately few voting rights.
	Subsidiaries: Subsidiaries are those entities in which the Company has an interest of more than one half of the voting rights or otherwise has power to govern the financial and operating policies of the entity. The acquisition method of accounting is used to account for the acquisition of subsidiaries. The cost of an acquisition is measured as the fair value of the assets given up, shares issued or liabilities undertaken at the date of acquisition. The excess of the cost of acquisition over the fair value of the net assets acquired and liabilities assumed is recorded as goodwill. All subsidiaries included in the consolidated financial statements are 100% owned, except for Navios Logistics, which is 63.8% owned by Navios Holdings and Navios Asia LLC (“Navios Asia”) and its wholly-owned subsidiaries, which were 51.0% owned by Navios Holdings, until May 2014, when Navios Holdings became the sole shareholder.
	Investments in Affiliates: Affiliates are entities over which the Company generally has between 20% and 50% of the voting rights, or over which the Company has significant influence, but it does not exercise control. Investments in these entities are accounted for under the equity method of accounting. Under this method the Company records an investment in the stock of an affiliate at cost, and adjusts the carrying amount for its share of the earnings or losses of the affiliate subsequent to the date of investment and reports the recognized earnings or losses in income. Dividends received from an affiliate reduce the carrying amount of the investment. The Company recognizes gains and losses in earnings for the issuance of shares by its affiliates, provided that the issuance of shares qualifies as a sale of shares. When the Company's share of losses in an affiliate equals or exceeds its interest in the affiliate, the Company does not recognize further losses, unless the Company has incurred obligations or made payments on behalf of the affiliate.
	Affiliates included in the financial statements accounted for under the equity method
	In the consolidated financial statements of Navios Holdings, the following entities are included as affiliates and are accounted for under the equity method for such periods: (i) Navios Partners and its subsidiaries (ownership interest as of December 31, 2014 was 20.0%, which includes a 2.0% general partner interest); (ii) Navios Acquisition and its subsidiaries (economic interest as of December 31, 2014 was 46.2%); (iii) Acropolis Chartering and Shipping Inc. (“Acropolis”) (economic interest as of December 31, 2014 was 35.0%); and (iv) Navios Europe and its subsidiaries (economic interest as of December 31, 2014 was 47.5%).

Use of Estimates	(c)      Use of Estimates: The preparation of consolidated financial statements in conformity with U.S.GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. On an on-going basis, management evaluates the estimates and judgments, including those related to uncompleted voyages, future drydock dates, the carrying value of investments in affiliates, the selection of useful lives for tangible assets, expected future cash flows from long-lived assets to support impairment tests, impairment test for goodwill provisions necessary for accounts receivables and demurrages, provisions for legal disputes, pension benefits, 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.
Cash and Cash Equivalents	(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.
Restricted Cash	(e)      Restricted Cash: As of December 31, 2014 and 2013, restricted cash included $1,974 and $1,451, respectively, which related to amounts held in a retention account in order to service debt and interest payments. Also included in restricted cash as of December 31, 2014 and 2013 are amounts held as security in the form of letters of guarantee or letters of credit totaling $590 for both reporting periods.
Insurance Claims	(f)      Insurance Claims: Insurance claims at each balance sheet date consist of claims submitted and/or claims in the process of compilation or submission (claims pending). They are recorded on an accrual basis and represent the claimable expenses, net of applicable deductibles, incurred through December 31 of each reporting period, which are probable 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.
Inventories	(g)      Inventories: Inventories, which are comprised of lubricants, bunkers (when applicable) and stock provisions on board of the vessels, as well as petroleum products held by Navios Logistics, are valued at cost as determined on the first-in, first-out basis.
Vessel, Port Terminal, Tanker Vessels, Barges, Pushboats and Other Fixed Assets, net	(h)      Vessels, Port Terminals, Tanker Vessels, Barges, Pushboats and Other Fixed Assets, net: Vessels, port terminals, tanker vessels, barges, pushboats and other fixed assets acquired as parts of business combinations are recorded at fair value on the date of acquisition and if acquired as an asset acquisition, are recorded at cost (including transaction costs). Vessels constructed by the company would be stated at historical cost, which consists of the contract price, capitalized interest and any material expenses incurred upon acquisition (improvements and delivery expenses). Subsequent expenditures for major improvements and upgrades are capitalized, provided they appreciably extend the life, increase the earnings capability or improve the efficiency or safety of the vessels. The cost and related accumulated depreciation of assets retired or sold are removed from the accounts at the time of sale or retirement and any gain or loss is included in the accompanying consolidated statements of comprehensive (loss)/income.
	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, port terminals, tanker vessels, barges, push boats and other fixed assets, after considering the estimated residual value.
	Annual depreciation rates used, which approximate the useful life of the assets are:
	Vessels	25 years
	Port terminals	5 to 40 years
	Tanker vessels, barges and push boats	15 to 45 years
	Furniture, fixtures and equipment	3 to 10 years
	Computer equipment and software	5 years
	Leasehold improvements	shorter of lease term or 6 years
	Management estimates the residual values of the Company's dry bulk vessels based on a scrap value cost of steel times the weight of the ship noted in lightweight tons (“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 the depreciation expense in the period of the revision and future periods. Until December 31, 2012, management estimated the residual values of the Company's 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.
	Management estimates the useful life of its vessels to be 25 years from the vessel's original construction. However, when regulations place limitations on the ability of a vessel to trade on a worldwide basis, its useful life is re-estimated to end at the date such regulations become effective. An increase in the useful life of a vessel or in its residual value would have the effect of decreasing the annual depreciation charge and extending it into later periods. A decrease in the useful life of a vessel or in its residual value would have the effect of increasing the annual depreciation charge.
Deposits for Vessels, Port Terminals, and Other Fixed Assets	(i)      Deposits for Vessels, Port Terminals and Other Fixed Assets: This represents amounts paid by the Company in accordance with the terms of the purchase agreements for the construction of vessels, port terminals and other long-lived fixed assets. Deposits for vessels, port terminals and other fixed assets also include pre-delivery expenses. Pre-delivery expenses represent any direct costs to bring the asset to the location and condition necessary for it to be capable of operating in the manner intended by management. Interest costs incurred during the construction (until the asset is substantially complete and ready for its intended use) are capitalized. Capitalized interest for the years ended December 31, 2014, 2013 and 2012 amounted to $2,334, $1,831 and $1,453, respectively.
Assets Held for Sale
	(j)      Assets Held for Sale: It is the Company's policy to dispose of vessels and other fixed assets when suitable opportunities occur and not necessarily to keep them until the end of their useful life. The Company classifies assets and disposal groups as being held for sale when the following criteria are met: management has committed to a plan to sell the asset (disposal group); the asset (disposal group) is available for immediate sale in its present condition; an active program to locate a buyer and other actions required to complete the plan to sell the asset (disposal group) have been initiated; the sale of the asset (disposal group) is probable, and transfer of the asset (disposal group) is expected to qualify for recognition as a completed sale within one year; the asset (disposal group) is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. Long-lived assets or disposal groups classified as held for sale are measured at the lower of their carrying amount or fair value less cost to sell. These assets are not depreciated once they meet the criteria to be held for sale. No assets were classified as held for sale in any of the periods presented.
Impairment of Long Lived Assets	(k)      Impairment of Long Lived Assets: Vessels, other fixed assets and other long-lived assets held and used by Navios Holdings are reviewed periodically for potential impairment whenever events or changes in circumstances indicate that the carrying amount of a particular asset may not be fully recoverable. Navios Holdings' 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 asset group and compared to the carrying value of the vessel, the unamortized portion of deferred drydock and special survey costs related to the vessel, and the related carrying value of the intangible assets with respect to the time charter agreement attached to that vessel or the carrying value of deposits for newbuildings. Within the shipping industry, vessels are customarily bought and sold with a charter attached. The value of the charter may be favorable or unfavorable when comparing the charter rate to then-current market rates. The loss recognized either on impairment (or on disposition) will reflect the excess of carrying value over fair value (selling price) for the vessel asset group.
	During the fourth quarter of fiscal year 2014, management concluded that events occurred and circumstances had changed, which indicated that potential impairment of Navios Holdings' long-lived assets might exist. These indicators included continued deterioration in the spot market, and the related impact of the current dry bulk sector has on management's expectation for future revenues. As a result, an impairment assessment of long-lived assets (step one) was performed.
	The Company 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 deferred drydock and special survey costs related to the vessel and the carrying value of the related intangible assets. 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 (the Company's remaining charter agreement rates) and an estimated daily time charter equivalent for the unfixed days (based on 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 excluding days of scheduled off-hires, running cost based on current year actual, assuming an annual increase of 3.0% after 2016 and a utilization rate of 99.8% based on the fleet's historical performance.
	For the deposits for new building vessels, the net cash flows also included the future cash out flows to make vessels ready for use, all remaining progress payments to shipyards and other pre-delivery expenses (e.g. capitalized interest).
	The assessment concluded that step two of the impairment analysis was not required and no impairment of vessels, deposits for vessel acquisitions and the related intangible assets existed as of December 31, 2014 and 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 typically 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 the charter rate trends and the length of the market downturn, vary significantly from our forecasts, Navios Holdings may be exposed to material impairment charges in the future.
	No impairment loss was recognized for any of the periods presented.
Deferred Drydock and Special Survey Costs	(l)      Deferred Drydock and Special Survey Costs: The Company's vessels, barges and push boats are subject to regularly scheduled drydocking and special surveys which are carried out every 30 and 60 months, respectively, for ocean-going vessels, and every 84 months for push boats and barges, 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 drydocking and special surveys are deferred and amortized over the above periods or to the next drydocking or special survey date if such date has been determined. Unamortized drydocking or special survey costs of vessels, barges and push boats sold are written-off to income in the year the vessel, barge or push boat is sold.
	Costs capitalized as part of the drydocking or special survey consist principally of the actual costs incurred at the yard, and expenses relating to spare parts, paints, lubricants and services incurred solely during the drydocking or special survey period. For each of the years ended December 31, 2014, 2013 and 2012, the amortization of deferred drydockand special survey costs was $12,263, $9,581, and $7,289, respectively.
Deferred Financing Costs	(m)      Deferred Financing Costs: Deferred financing costs include fees, commissions and legal expenses associated with obtaining or modifying 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 and write-off of deferred financing costs for each of the years ended December 31, 2014, 2013 and 2012 were $4,061, $5,384 and $6,309, respectively. See Note 17.
Goodwill and Other Intangibles	(n)      Goodwill and Other Intangibles
	(i)         Goodwill: Goodwill is tested for impairment at the reporting unit level at least annually.
	The Company evaluates impairment of goodwill using a two-step process. First, the aggregate fair value of the reporting unit is compared to its carrying amount, including goodwill (step one). The Company determines the fair value of the reporting unit based on discounted cash flow analysis and believes that the discounted cash flow analysis is the best indicator of fair value for its individual reporting units.
	The fair value for goodwill impairment testing was estimated using the expected present value of future cash flows, using judgments and assumptions that management believes were appropriate in the circumstances. The significant factors and assumptions the Company used in its discounted cash flow analysis included: EBITDA, the discount rate used to calculate the present value of future cash flows and future capital expenditures. EBITDA assumptions included revenue assumptions, general and administrative expense growth assumptions, and direct vessel expense growth assumptions. The future cash flows from shipping operations were determined by considering the charter revenues from existing time charters for the fixed fleet days (the Company's remaining charter agreement rates) and an estimated daily time charter equivalent for the non-fixed days (based on a combination of one-year average historical charter rates and the 10-year average historical charter rates adjusted for outliers, as available for each type of vessel), which the Company believes is an objective approach for forecasting charter rates over an extended time period for long lived assets. The future cash flows from logistics operations were determined principally by combining revenues from existing contracts and estimated revenues based on the historical performance of the segment, including utilization rates and actual storage capacity.
	If the fair value of a reporting unit exceeds the carrying amount, no impairment exists. If the carrying amount of the reporting unit exceeds the fair value, then the Company must perform the second step to determine the implied fair value of the reporting unit's goodwill and compare it with its carrying amount. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit to all the assets and liabilities of that reporting unit, as if the reporting unit had been acquired in a business combination and the fair value of the reporting unit was the purchase price. If the carrying amount of the goodwill exceeds the implied fair value, then goodwill impairment is recognized by writing the goodwill down to its implied fair value.
	No impairment loss was recognized for any of the periods presented.
	(ii)        Intangibles Other Than Goodwill: Navios Holdings' intangible assets and liabilities consist of favorable lease terms, unfavorable lease terms, customer relationships, trade name and port terminal operating rights. The fair value of the trade name was determined based on the “relief from royalty” method which values the trade name based on the estimated amount that a company would have to pay in an arm's length transaction to use that trade name. The asset is being amortized under the straight line method over 32 years. Navios Logistics' trade name is being amortized under the straight line method over 10 years.
	The fair value of customer relationships was determined based on the “excess earnings” method, which relies upon the future cash flow generating ability of the asset. The asset is amortized under the straight line method.
	Other intangibles that are being amortized, such as customer relationships and port terminal operating rights, would be considered impaired if their carrying value could not be recovered from the future undiscounted cash flows associated with the asset.
	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 the Company to make significant assumptions and estimates of many variables including market charter rates, expected future charter rates, the level of utilization of the Company's vessels and the Company's 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 the Company's 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 consolidated statements of comprehensive (loss)/income in the “Depreciation and amortization” line item.
	The amortizable value of favorable leases would be considered impaired if its fair market value 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. No impairment loss was recognized for any the periods presented.
	Vessel purchase options that are included in favorable leases are not amortized and when the purchase option is exercised the asset is capitalized as part of the cost of the vessel and depreciated over the remaining useful life of the vessel and if not exercised, the intangible asset is written off. Vessel purchase options that are included in unfavorable lease terms are not amortized and when the purchase option is exercised by the charterer and the underlying vessel is sold, it will be recorded as part of gain/loss on sale of the assets. If the option is not exercised at the expiration date it is written-off in the consolidated statements of comprehensive (loss)/income.
	The weighted average amortization periods for intangibles are:
	Intangible assets/liabilities		Years
	Trade name		21
	Favorable lease terms		11.1
	Unfavorable lease terms		9.4
	Port terminal operating rights		32.5
	Customer relationships		20.0-45.0
	See also Note 7.
Foreign Currency Translation
	(o)      Foreign Currency Translation: The Company's functional and reporting currency is the U.S. dollar. The Company 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. The Company's subsidiaries in Uruguay, Argentina, Brazil and Paraguay transact a nominal amount of their operations in Uruguayan pesos, Argentinean pesos, Brazilian reales and Paraguayan guaranies whereas the Company's wholly-owned vessel subsidiaries and the vessel management subsidiaries transact a nominal amount of their operations in Euros; however, all of the subsidiaries' primary cash flows are U.S. dollar denominated. The financial statements of the foreign operations are translated using the exchange rate at the balance sheet date except for property and equipment and equity, which are translated at historical rates. Transactions in currencies other than the functional currency are translated at the exchange rate in effect at the date of each transaction. Differences in exchange rates during the period between the date a transaction denominated in a foreign currency is consummated and the date on which it is either settled or translated, are recognized in the statements of comprehensive (loss)/income. The foreign currency gains/(losses) recognized under the caption “Other income” and “Other expense”, respectively,  in the consolidated statements of comprehensive (loss)/income for each of the years ended December 31, 2014, 2013 and 2012, were $1,945, $184 and ($217), respectively.
Provisions	(p)      Provisions: The Company, in the ordinary course of business, is subject to various claims, suits and complaints. Management, in consultation with internal and external advisers, will provide for a contingent loss in the financial statements if the contingency had occurred at the date of the financial statements and the likelihood of loss was probable and the amount can be reasonably estimated. If the Company has determined that the reasonable estimate of the loss is a range and there is no best estimate within the range, the Company will provide for the lower amount within the range. See Note 13, “Commitments and Contingencies” for further discussion.
	The Company participates in Protection and Indemnity (P&I) insurance plans provided by mutual insurance associations known as P&I clubs. Under the terms of these plans, participants may be required to pay additional premiums (supplementary calls) to fund operating deficits incurred by the clubs (“back calls”). Obligations for back calls are accrued annually based on information provided by the P&I clubs.
	Provisions for estimated losses on uncompleted voyages and vessels under time charter are provided for in the period in which such losses are determined. As of December 31, 2014 and 2013, the balance for provision for loss making voyages in progress was $1,893 and $801, respectively.
Segment Reporting	(q)      Segment Reporting: Operating segments, as defined, are components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. Based on the Company's methods of internal reporting and management structure, the Company currently has two reportable segments: the Dry Bulk Vessel Operations segment and the Logistics Business segment.
Revenue and Expense Recognition	(r)      Revenue and Expense Recognition:
	Revenue Recognition: Revenue is recorded when services are rendered, the Company has a signed charter agreement or other evidence of an arrangement, the price is fixed or determinable, and collection is reasonably assured. The Company generates revenue from transportation of cargo, time charter of vessels, port terminal operations, bareboat charters, contracts of affreightment/voyage contracts, demurrages and contracts covering dry or liquid port terminal operations.
	Voyage revenues for the transportation of cargo are recognized ratably over the estimated relative transit time of each voyage. A voyage is deemed to commence when a vessel 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, the Company agrees to provide a vessel for the transportation of specific goods between specific ports in return for payment of an agreed upon freight rate per ton of cargo.
	Revenues are recorded net of address commissions. Address commissions represent a discount provided directly to the charterers based on a fixed percentage of the agreed upon charter rate. Since address commissions represent a discount (sales incentive) on services rendered by the Company and no identifiable benefit is received in exchange for the consideration provided to the charterer, these commissions are presented as a reduction of revenue.
	Revenue from time chartering and bareboat chartering is earned and recognized on a daily basis as the service is delivered. Revenue from contracts of affreightment(“COA”)/voyage contracts relating to our barges is recognized based upon the percentage of voyage completion. A voyage is deemed to commence upon the departure of the barge after discharge under the previous voyage and is deemed to end upon the completion of discharge under the current voyage. The percentage of voyage completion is based on the days traveled as of the balance sheet date divided by the total days expected for the voyage. The position of the barge at the balance sheet date is determined by the days traveled as of the balance sheet date over the total voyage of the pushboat having the barge in tow. Revenue arising from contracts that provide our customers with continuous access to convoy capacity is recognized ratably over the period of the contracts.
	Demurrage income represents payments made by the charterer to the vessel owner when loading or discharging time exceeds the stipulated time in the voyage charter and is recognized as it is earned.
	Revenues arising from contracts that provide our customers with continuous access to convoy capacity are recognized ratably over the period of the contracts.
	Profit-sharing revenues are calculated at an agreed percentage of the excess of the charterer's average daily income (calculated on a quarterly or half-yearly basis) over an agreed amount and accounted for on an accrual basis based on provisional amounts and for those contracts that provisional accruals cannot be made due to the nature of the profit sharing elements, these are accounted for on the actual cash settlement.
	Revenues from time chartering of vessels are accounted for as operating leases and are thus recognized on a straight line basis as the average revenue over the rental periods of such charter agreements as service is performed, except for loss generating time charters, in which case the loss is recognized in the period when such loss is determined. A time charter involves placing a vessel at the charterer's disposal for a period of time during which the charterer uses the vessel in return for the payment of a specified daily hire rate. Short period charters for less than three months are referred to as spot-charters. Charters extending three months to a year are generally referred to as medium-term charters. All other charters are considered long-term. Under time charters, operating costs such as for crews, maintenance and insurance are typically paid by the owner of the vessel.
	Revenues from port terminal operations consist of an agreed flat fee per ton and cover the services performed to unload barges (or trucks), transfer the product into silos for temporary storage and then loading the ocean-going vessels. Revenues are recognized upon completion of loading the ocean-going vessels. Additionally, fees are charged for vessel dockage and for storage time in excess of contractually specified terms. Dockage revenues are recognized ratably up to completion of loading. Storage fees are assessed and recognized when the product remains in the silo storage beyond the contractually agreed time allowed. Storage fee revenue is recognized ratably over the storage period and ends when the product is loaded onto the ocean-going vessel.
	Revenues from liquid port terminal operations consist mainly of sales of petroleum products in the Paraguayan market. Additionally, revenues consist of an agreed flat fee per cubic meter to cover the services performed to unload barges, transfer the products into the tanks for temporary storage and then loading the trucks. Revenues are recognized upon completion of loading the trucks. Additionally, fees are charged for storage time in excess of contractually specified terms. Storage fee revenue is recognized ratably over the storage period and ends when the product is loaded onto the trucks.
	Recovery of lost revenue under credit default insurance for charterers is accounted for as gain contingency and is recognized when all contingencies are resolved. The amount of recovery of lost revenue is recorded within the caption “Revenue” and any amount recovered in excess of the lost revenue is recorded within the caption “Other income”.
	Expenses related to our revenue-generating contracts are recognized as incurred.
	Administrative fee revenue from affiliates: Administrative fee revenue from affiliates consists of fees earned on the provision of administrative services pursuant to administrative services agreements with our affiliates (Refer to Note 15). Administrative services 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 general and administrative services. These revenues are recognized as the services are provided to affiliates. The general and administrative expenses incurred on behalf of affiliates are determined based on a combination of actual expenses incurred on behalf of the affiliates as well as a reasonable allocation of expenses that are not affiliate specific but incurred on behalf of all affiliates.
	Forward Freight Agreements (“FFAs”): Realized gains or losses from FFAs are recognized monthly concurrent with cash settlements. In addition, FFAs are “marked to market” quarterly to determine the fair values which generate unrealized gains or losses. Trading of FFAs could lead to material fluctuations in the Company's reported results from operations on a period to period basis. See Note 11.
	Deferred Income and Cash Received In Advance: 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.
	Time Charter, Voyage and Logistics Business Expenses: Time charter, voyage and logistics business expenses comprise all expenses related to each particular voyage, including time charter hire paid and voyage freight paid, bunkers, port charges, canal tolls, cargo handling, agency fees and brokerage commissions. Also included in time charter, voyage and logistics business expenses are charterers' liability insurances, provision for losses on time charters and voyages in progress at year-end, direct port terminal expenses and other miscellaneous expenses.
	Direct Vessel Expenses: Direct vessel expenses consist of all expenses relating to the operation of vessels, including crewing, repairs and maintenance, insurance, stores and lubricants and miscellaneous expenses such as communications and amortization of drydocking and special survey costs net of related party management fees.
	Prepaid Voyage Costs: Prepaid voyage costs relate to cash paid in advance for expenses associated with voyages. These amounts are recognized as expenses over the voyage or charter period.
Employee benefits	(s)   Employee benefits:
	Pension and Retirement Obligations-Crew: The Company's ship-owning subsidiaries employ the crew on board under short-term contracts (usually up to nine months) and, accordingly, they are not liable for any pension or post-retirement benefits.
	Provision for Employees' Severance and Retirement Compensation: The employees in the Company's office in Greece are protected by Greek labor law. According to the law, the Company is required to pay retirement indemnities to employees upon dismissal or upon leaving with an entitlement to a full security retirement pension. The amount of compensation is based on the number of years of service and the amount of remuneration at the date of dismissal or retirement up to a maximum of two years' salary. If the employees remain in the employment of the Company until normal retirement age, they are entitled to retirement compensation which is equal to 40% of the compensation amount that would be payable if they were dismissed at that time. The number of employees that will remain with the Company until retirement age is not known. The Company considers this plan equivalent to a lump sum defined benefit pension plan and accounts for it under relevant guidance on employer's accounting for pensions. The Company is required to annually value the statutory terminations indemnities liability. Management obtains a valuation from independent actuaries to assist in the calculation of the benefits. The Company provides, in full, for the employees' termination indemnities liability. This liability amounted to $819 and $660 at December 31, 2014 and 2013, respectively.
	U.S. Retirement Savings Plan: The Company sponsors a 401(k) retirement savings plan, which is categorized as a defined contribution plan. The plan is available to full time employees who meet the plan's eligibility requirements. The plan permits employees to make contributions up to 15% of their annual salary with the Company matching up to the first 6%. The Company makes monthly contributions (matching contributions) to the plan based on amounts contributed by employees. Subsequent to making the matching contributions, the Company has no further obligations. The Company may make an additional discretionary contribution annually if such a contribution is authorized by the Board of Directors. The plan is administered by an independent professional firm that specializes in providing such services. See Note 12.
	Other Post-Retirement Obligations: The Company has a legacy pension arrangement for certain Bahamian, Uruguayan and former Navios Corporation employees. The entitlement to these benefits is only to these former employees. The expected costs of these benefits are accrued each year, using an accounting methodology similar to that for defined benefit pension plans. These obligations are valued annually by independent actuaries.
	Stock-Based Compensation: In December 2014, 2013 and 2012, the Company authorized the issuance of shares of restricted common stock, restricted stock units and stock options in accordance with the Company's stock option plan for its employees, officers and directors. These awards of restricted common stock, restricted stock units and stock options are based on service conditions only and vest over three years. In December 2013 and 2014, the Company also authorized the issuance of shares of restricted common stock, restricted stock units and stock options for its employees, officers and directors that vest on April 30, 2015 and  June 2, 2016, respectively, upon achievement of certain internal performance criteria including certain targets on operational performance and cost efficiency. See Note 12.
	The fair value of stock option grants is determined with reference to option pricing model and principally adjusted Black-Scholes models. The fair value of restricted stock and restricted stock units is determined by reference to the quoted stock price on the date of grant. Compensation expense, net of estimated forfeitures, is recognized based on a graded expense model over the vesting period. Compensation expense for the awards that vest upon achievement of the performance criteria is recognized when it is probable that the performance criteria will be met and are being accounted for as equity.
Financial Instruments	(t)      Financial Instruments: Financial instruments carried on the balance sheet include cash and cash equivalents, restricted cash, trade receivables and payables, other receivables and other liabilities, long-term debt, capital leases and available-for-sale securities. 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: The Company's activities expose it to a variety of financial risks including fluctuations in future freight rates, time charter hire rates, fuel prices and 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: The Company closely monitors its credit exposure to customers and counterparties for credit risk. The Company has policies in place to ensure that it trades with customers and counterparties with an appropriate credit history. Derivative counterparties and cash transactions are limited to high quality credit financial institutions.
	Interest Rate Risk: Any differential to be paid or received on an interest rate swap agreement is recognized as a component of gain/loss on derivatives over the period of the agreement. Gains and losses on early termination of interest rate swaps are reflected in the consolidated statements of comprehensive (loss)/income. The effective portion of changes in the fair value of interest rate swap agreements that are designated and qualify as cash flow hedges are recognized in equity.
	Liquidity Risk: Prudent liquidity risk management implies maintaining sufficient cash and marketable securities, the availability of funding through an adequate amount of committed credit facilities and the ability to close out market positions. The Company monitors cash balances appropriately to meet working capital needs.
	Foreign Exchange Risk: Foreign currency transactions are translated into the measurement currency at rates prevailing on the dates of the relevant 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 comprehensive (loss)/income.
	Accounting for Derivative Financial Instruments and Hedging Activities: The Company may enter into dry bulk shipping FFAs as economic hedges relating to identifiable ship and/or cargo positions and as economic hedges of transactions the Company expects to carry out in the normal course of its shipping business. By utilizing certain derivative instruments, including dry bulk shipping FFAs, the Company manages the financial risk associated with fluctuating market conditions. In entering into these contracts, the Company has assumed the risks that might arise from the possible inability of counterparties to perform in accordance with the terms of their contracts.
	The Company also trades dry bulk shipping FFAs which are cleared through LCH, the London clearing house. LCH calls for both base and margin collateral, which are funded by Navios Holdings, and which in turn substantially eliminate counterparty risk. Certain portions of these collateral funds may be restricted at any given time as determined by LCH.
	At the end of each calendar quarter, the fair value of dry bulk shipping FFAs traded over-the-counter are determined from an index published in London, United Kingdom and the fair value of those FFAs traded with LCH is determined from the LCH valuations.
	The Company records all of its derivative financial instruments and hedges as economic hedges.
	The Company classifies cash flows related to derivative financial instruments within cash provided by operating activities in the consolidated statements of cash flows.
(Loss)/Earnings Per Share	(u)      (Loss)/Earnings Per Share: Basic (losses)/earnings per share are computed by dividing net (loss)/income attributable to Navios Holdings common stockholders by the weighted average number of shares of common stock outstanding during the periods presented. Diluted earnings per share reflect the potential dilution that would occur if securities or other contracts to issue common stock were exercised or converted. Dilution has been computed by the treasury stock method whereby all of the Company's dilutive securities (stock options and warrants) are assumed to be exercised and the proceeds are used to repurchase common shares at the weighted average market price of the Company's common stock during the relevant periods. The incremental shares (the difference between the number of shares assumed issued and the number of shares assumed purchased) are included in the denominator of the diluted earnings per share computation. Restricted stock and restricted stock units (vested and unvested) are included in the calculation of the diluted earnings per share, based on the weighted average number of restricted stock and restricted stock units assumed to be outstanding during the period. Convertible shares are included in the calculation of the diluted earnings per share, based on the weighted average number of convertible shares assumed to be outstanding during the period. See also Note 19.
Income Taxes	(v)      Income Taxes: The Company is a Marshall Islands Corporation. Pursuant to various treaties and the United States Internal Revenue Code, the Company believes that substantially all its operations are exempt from income taxes in the Marshall Islands and the United States of America. The tax expense reflected in the Company's consolidated financial statements for the years ended December 31, 2014, 2013 and 2012 was mainly attributable to its subsidiaries in South America, which are subject to the Argentinean and Paraguayan income tax regimes.
	The asset and liability method is used to account for future income taxes. Under this method, future income tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts and the tax bases of assets and liabilities. Future income tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on future income tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A deferred tax asset is recognized for temporary differences that will result in deductible amounts in future years. A valuation allowance is recognized if, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred tax asset will not be realized.
Dividends	(w)      Dividends: Dividends are recorded in the Company's financial statements in the period in which they are declared. Navios Holdings paid $25,228, $24,710 and $30,730 to its common stockholders during the years ended December 31, 2014, 2013 and 2012, respectively, and $7,502, $1,695 and $1,705 to its preferred stockholders during the years ended December 31, 2014, 2013 and 2012, respectively.
Guarantees	(x)      Guarantees: A liability for the fair value of the obligation undertaken in issuing the guarantee is recognized. The recognition of fair value is not required for certain guarantees such as the parent's guarantee of a subsidiary's debt to a third party or guarantees on product warranties. For those guarantees excluded from the above guidance requiring the fair value recognition provision of the liability, financial statement disclosures of their terms are made.
	On November 15, 2012, the Company agreed to provide Navios Partners with guarantees against counterparty default on certain existing charters (see also Notes 15 and 23).
Leases	(y)      Leases: Vessel leases where Navios Holdings is regarded as the lessor are classified as either finance leases or operating leases based on an assessment of the terms of the lease.
	For charters classified as finance leases the minimum lease payments are recorded as the gross investment in the lease. The difference between the gross investment in the lease and the sum of the present values of the two components of the gross investment is recorded as unearned income which is amortized to income over the lease term as finance lease interest income to produce a constant periodic rate of return on the net investment in the lease.
	For charters classified as operating leases where Navios Holdings is regarded as the lessor, refer to Note 2(r) “Revenue and Expense Recognition”.
	For charters classified as operating leases where Navios Holdings is regarded as the lessee, the expense is recognized on a straight line basis over the rental periods of such charter agreements. The expense is included under the line item  “Time charter, voyage and logistics business expenses”.
Treasury Stock	(z)      Treasury Stock: Treasury stock is accounted for using the cost method. Excess of the purchase price of the treasury stock acquired, plus direct acquisition costs over its par value is recorded in additional paid-in capital.
Trade Accounts Receivable	(aa)      Trade Accounts Receivable: The amount shown as accounts receivable, trade, at each balance sheet date, includes receivables from charterers for hire, freight and demurrage billings and FFA counterparties, 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.
Convertible Preferred Stock	(ab)    Convertible Preferred Stock: The Company's 2% Mandatorily Convertible Preferred Stock (“Preferred Stock”) is recorded at fair market value on the date of issuance. The fair market value is determined using a binomial valuation model. The model which is used takes into account the credit spread of the Company, the volatility of its stock, as well as the price of its stock at the issuance date. Each preferred share has a par value of $0.0001. Each holder of Preferred Stock is entitled to receive an annual dividend equal to 2.0% on the nominal value of the Preferred Stock, payable quarterly, until such time as the Preferred Stock converts into common stock. Five years after the issuance date, 30.0% of the then-outstanding shares of Preferred Stock shall automatically convert into shares of common stock at a conversion price equal to $10.00 per share of common stock with the remaining balance of the then-outstanding shares of Preferred Stock being converted into shares of common stock under the same terms 10 years after their issuance date. At any time following the third anniversary from their issuance date, if the closing price of the common stock has been at least $20.00 per share, for 10 consecutive business days, the remaining balance of the then-outstanding preferred shares shall automatically convert at a conversion price equal to $14.00 per share of common stock. The holders of Preferred Stock are entitled, at their option, at any time following their issuance date and prior to their final conversion date, to convert all or any such then-outstanding preferred shares into common stock at a conversion price equal to $14.00 per common stock.
Cumulative Redeemable Perpetual Preferred Stock	(ac)     Cumulative Redeemable Perpetual Preferred Stock: The Company's 2,000,000 American Depositary Shares, Series G Cumulative Redeemable Perpetual Preferred Stock (the “Series G”) and the 4,800,000 American Depositary Shares, Series H Cumulative Redeemable Perpetual Preferred Stock (the “Series H”) are recorded at fair market value on issuance. Each of the shares represents 1/100th of a share of the Series G, with a liquidation preference of $2,500.00 per share ($25.00 per American Depositary Share). Dividends are payable quarterly in arrears on the Series G at a rate of 8.75% per annum and on the Series H at a rate of 8.625% per annum of the stated liquidation preference. At any time on or after January 28, 2019, the Series G may be redeemed at the Company's option and at any time on or after July 8, 2019, the Series H may be redeemed at the Company's option (and the American Depositary Shares can be caused to be redeemed), in whole or in part, out of amounts legally available therefore, at a redemption price of $2,500.00 per share (equivalent to $25.00 per American Depositary Share) plus an amount equal to all accumulated and unpaid dividends thereon to the date of redemption, whether or not declared. The Company has accounted for these shares as equity.
Investment in Available-for-Sale Securities	(ad)      Investment in Available-for-Sale Securities: The Company classifies its existing marketable equity securities as available-for-sale. These securities are carried at fair value, with unrealized gains and losses excluded from earnings and reported directly in stockholders' equity as a component of other comprehensive (loss)/income unless an unrealized loss is considered “other-than-temporary,” in which case it is transferred to the consolidated statements of comprehensive (loss)/income. Management evaluates securities for other than temporary impairment (“OTTI”) on a quarterly basis. Consideration is given to (i) the length of time and the extent to which the fair value has been less than cost, (ii) the financial condition and near-term prospects of the investee, and (iii) the intent and ability of the Company to retain its investment in the investee for a period of time sufficient to allow for any anticipated recovery in fair value.
	Investment in Equity Securities: Navios Holdings evaluates its investments in Navios Acquisition, Navios Partners and Navios Europe for OTTI on a quarterly basis. Consideration is given to (i) the length of time and the extent to which the fair value has been less than the carrying value, (ii) the financial condition and near-term prospects of Navios Partners, Navios Acquisition and Navios Europe, and (iii) the intent and ability of the Company to retain its investment in Navios Acquisition, Navios Partners and Navios Europe for a period of time sufficient to allow for any anticipated recovery in fair value.
Financial Instruments and Fair Value	(ae)      Financial Instruments and Fair Value: Guidance on Fair Value Measurements provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level I measurements) and the lowest priority to unobservable inputs (Level III measurements).
	A financial instrument's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. In determining the appropriate levels, the Company performs a detailed analysis of the assets and liabilities that are subject to guidance on Fair Value Measurements.
Recent Accounting Pronouncements	(af)      Recent Accounting Pronouncements:
	In April 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-08, “Presentation of Financial Statements and Property, Plant and Equipment”, changing the presentation of discontinued operations on the statements of income and other requirements for reporting discontinued operations. Under the new standard, a disposal of a component or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity's operations and financial results when the component meets the criteria to be classified as held-for-sale or is disposed. The amendments in this update also require additional disclosures about discontinued operations and disposal of an individually significant component of an entity that does not qualify for discontinued operations. The new accounting guidance is effective for interim and annual periods beginning after December 15, 2014. The adoption of the new standard is not expected to have a material impact on Navios Holdings' results of operations, financial position or cash flows.
	In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers", changing the method used to determine the timing and requirements for revenue recognition on the statements of comprehensive income. Under the new standard, an entity must identify the performance obligations in a contract, the transaction price and allocate the price to specific performance obligations to recognize revenue when the obligation is completed. The amendments in this update also require disclosure of sufficient information to allow users to understand the nature, amount, timing and uncertainty of revenue and cash flow arising from contracts. The new accounting guidance is effective for interim and annual periods beginning after December 15, 2016. Early adoption is not permitted. The Company is currently reviewing the effect of ASU No. 2014-09 on its revenue recognition.
	In January 2015, the FASB issued ASU No. 2015-01, “Income Statement-Extraordinary and Unusual Items”. This standard eliminates the concept of extraordinary and unusual items from U.S. GAAP. The new standard is effective for annual and interim periods after December 15, 2015. Early adoption is permitted. We plan to adopt this standard effective January 1, 2016. The adoption of this ASU is not expected to have a material impact on the Company's results of operations, financial position or cash flows.
	In February 2015, the FASB issued ASU No. 2015-02, “Consolidation (Topic 810) - Amendments to the Consolidation Analysis”, which amends the criteria for determining which entities are considered VIEs, amends the criteria for determining if a service provider possesses a variable interest in a VIE and ends the deferral granted to investment companies for application of the VIE consolidation model. The ASU is effective for interim and annual periods beginning after December 15, 2015. Early application is permitted. We do not expect the adoption of this ASU to have a material impact on the  Company's results of operations, financial position or cash flows, except if Navios Holdings was to enter into new arrangements in 2015 that fall into the scope prior to adoption of this standard.

Concentration of credit risk with respect to accounts receivable	Concentration of credit risk with respect to accounts receivable are limited due to the Company's large number of customers, who are internationally dispersed and have a variety of end markets in which they sell. Due to these factors, management believes that no additional credit risk beyond amounts provided for collection losses is inherent in the Company's trade receivables. For the year ended December 31, 2014, one customer accounted for 11.9% of the Company's revenue and for the years ended December 31, 2013 and 2012, none of the Company's customers accounted for more than 10% of the Company's revenue.
