Description of Business	Jun. 30, 2019
DESCRIPTION OF BUSINESS [Abstract]
DESCRIPTION OF BUSINESS	NOTE 1: DESCRIPTION OF BUSINESS Navios Maritime Holdings Inc. (“Navios Holdings” or the “Company”) (NYSE: NM) is a global seaborne shipping and logistics company focused on the transport and transshipment of dry bulk commodities, including iron ore, coal and grain. Navios Logistics Navios South American Logistics Inc. (“Navios Logistics”), a consolidated subsidiary of the Company, is one of the largest logistics companies in the Hidrovia region of South America, focusing on the Hidrovia river system, the main navigable river system in the region, and on cabotage trades along the eastern coast of South America. Navios Logistics is focused on providing its customers integrated transportation, storage and related services through its port facilities, its large, versatile fleet of dry and liquid cargo barges and its product tankers. Navios Logistics serves the needs of a number of growing South American industries, including mineral and grain commodity providers as well as users of refined petroleum products. As of June 30, 2019, Navios Holdings owned 63.8% of Navios Logistics. Navios Containers Navios Maritime Containers L.P. (“Navios Containers”) (NASDAQ: NMCI) is a growth vehicle dedicated to the container sector of the maritime industry. Navios Maritime Containers Inc. registered its shares on the Norwegian Over-The-Counter Market (N-OTC) on June 12, 2017 under the ticker “NMCI”. On November 30, 2018, Navios Maritime Containers Inc. was converted into a limited partnership. In connection with the conversion, Navios Maritime Containers GP LLC, a Republic of the Marshall Islands limited liability company and wholly-owned subsidiary of Navios Holdings, was admitted as Navios Containers’ general partner and holds a non-economic interest that does not provide the holder with any rights to profits or losses of, or distribution by, the partnership. As a result of holding the general partner interest, control was obtained by Navios Holdings due to the fact that the general partner has exclusive management authority over Navios Containers’ operations, controls the appointment of three of the seven members of Navios Containers’ board of directors and has veto rights over certain significant actions of Navios Containers. The limited partners may not remove the general partner without the affirmative vote of at least 75% of the outstanding units (including units held by the general partner and its affiliates), voting as a single class. In addition, limited partners have no right to participate in the operation, management or control of Navios Containers’ business or transact any business in Navios Containers’ name. The general partner has the power to oversee and direct the partnership’s operations and to manage and determine the partnership’s strategies and policies on an exclusive basis and therefore, has the power to govern the financial and operating policies of Navios Containers. As of that date, Navios Holdings obtained control over Navios Containers and consequently the results of operations of Navios Containers are consolidated under Navios Holdings. As of June 30, 2019, Navios Holdings had a 3.7% ownership interest in Navios Containers. Navios Partners Navios Maritime Partners L.P. (“Navios Partners”) (NYSE:NMM) is an international owner and operator of dry cargo vessels and is engaged in seaborne transportation services of a wide range of dry cargo commodities including iron ore, coal, grain, fertilizer and also containers, chartering its vessels under medium to long-term charters. As of June 30, 2019, Navios Holdings owned a 20.5% interest in Navios Partners, including a 2.1% general partner interest. Navios Acquisition Navios Maritime Acquisition Corporation (“Navios Acquisition”) (NYSE: NNA), is an owner and operator of tanker vessels focusing on the transportation of petroleum products (clean and dirty) and bulk liquid chemicals. As of June 30, 2019, Navios Holdings’ ownership of the outstanding voting stock of Navios Acquisition was 35.4% and its economic interest was 36.0%. Navios Europe I On October 9, 2013, Navios Holdings, Navios Acquisition and Navios Partners established Navios Europe Inc. (“Navios Europe I”) and have economic interests of 47.5%, 47.5% and 5.0%, respectively. Navios Europe I is engaged in the marine transportation industry through the ownership of five tanker and five container vessels. Effective November 2014, Navios Holdings, Navios Acquisition and Navios Partners have voting interests of 50%, 50% and 0%, respectively.

(“Navios Europe II”) and have economic interests of 47.5%, 47.5% and 5.0%, respectively, and voting interests of 50%, 50% and 0%, respectively.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NOTE 2: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

(a) Basis of presentation: The accompanying interim condensed consolidated financial statements are unaudited, but, in the opinion of management, reflect all adjustments for a fair statement of Navios Holdings’ consolidated balance sheets, statements of comprehensive (loss)/income, statements of cash flows and statements of changes in equity for the periods presented. The results of operations for the interim periods are not necessarily indicative of results for the full year. The footnotes are condensed as permitted by the requirements for interim financial statements and accordingly, do not include information and disclosures required under United States generally accepted accounting principles (“U.S. GAAP”) for complete financial statements. All such adjustments are deemed to be of a normal recurring nature. These interim financial statements should be read in conjunction with the Company’s consolidated financial statements and notes included in Navios Holdings’ Annual Report for the year ended December 31, 2018 filed on Form 20-F with the Securities and Exchange Commission (“SEC”).

Change in accounting principles:

ASU 2016-02 Leases, ASC 842

On January 1, 2019, the Company adopted the requirements of ASU 2016-02 “Leases” as amended (“ASC 842” or the “new lease standard”). ASC 842 increases transparency and comparability among organizations by requiring a lessee to record right-of-use assets and related lease liabilities on its balance sheet when it commences an operating lease. The Company adopted ASC 842 using the modified retrospective transition method. Under this method, the cumulative effect of applying the new lease standard is recorded with no restatement of any comparative prior periods presented. As provided by ASC 842, the Company elected to record the required cumulative effect adjustments to the opening balance sheet in the period of adoption rather than in the earliest comparative period presented. As a result, prior periods as reported by the Company have not been impacted by the adoption of ASC 842. As required by ASC 842, the Company’s disclosures around its leasing activities have been significantly expanded to enable users of our condensed consolidated financial statements to assess the amount, timing and uncertainty of cash flows arising from lease arrangements. Please refer to Note 14.

Reverse Stock Split

On December 21, 2018, the Company’s common stockholders approved a one-for-ten reverse stock split of the Company’s outstanding shares of common stock (the “Reverse Stock Split”). The Reverse Stock Split was effective since January 3, 2019 and the common stock commenced trading on that date on a split-adjusted basis. As a result of the Reverse Stock Split, every ten shares of issued and outstanding common stock were combined into one issued and outstanding share of common stock, without any change in authorized shares or the par value per share. All issued and outstanding shares of common stock, redemption and conversion terms of preferred stock, options to purchase common stock and per share amounts contained in the consolidated financial statements have been retroactively adjusted to reflect the Reverse Stock Split for all periods presented. The retroactive application of the Reverse Stock Split reduced the number of shares of common stock outstanding from 128.4 million shares to 12.8 million shares as of December 31, 2018. The par value of the common stock remained at $0.0001 per share.

(b) Principles of consolidation: The accompanying interim condensed consolidated financial statements include the accounts of Navios Holdings, a Marshall Islands corporation, and its majority owned subsidiaries. All significant intercompany balances and transactions have been eliminated in the consolidated statements.

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. 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 and Navios Containers, which are 63.8% owned and 3.7% owned by Navios Holdings, respectively.

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 June 30, 2019 was 20.5%, which includes a 2.1% general partner interest); (ii) Navios Acquisition and its subsidiaries (economic interest as of June 30, 2019 was 36.0%); (iii) Navios Europe I and its subsidiaries (economic interest as of June 30, 2019 was 47.5%); (iv) Navios Europe II and its subsidiaries (economic interest as of June 30, 2019 was 47.5%); (v) Navios Containers and its subsidiaries (economic interest as of November 30, 2018, date of obtaining control, was 3.7%); and (vi) Acropolis Chartering and Shipping Inc. (“Acropolis”) (economic interest as of December 6, 2018, date of sale of investment, was 35.0%).

(c)	Revenue Recognition:

On January 1, 2018, the Company adopted the provisions of ASC 606, Revenue from Contracts with Customers (ASC 606). The guidance provides a unified model to determine how revenue is recognized. In doing so, the Company makes judgments including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price, and allocating the transaction price to each performance obligation. Revenue is recognized when (or as) the Company transfers promised goods or services to its customers in amounts that reflect the consideration to which the company expects to be entitled to in exchange for those goods or services, which occurs when (or as) the Company satisfies its contractual obligations and transfers control of the promised goods or services to its customers. Revenues are recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In determining the appropriate amount of revenue to be recognized as it fulfills its obligations under its agreements, the Company performs the following steps: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations, including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations based on estimated selling prices; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation.

The Company’s contract revenues from time chartering and pooling arrangements are governed by ASC 842 “Leases”. See Note 14. Upon adoption of ASC 842, the timing and recognition of earnings from the pool arrangements and time charter contracts to which the Company is party did not change from previous practice. The Company has determined to recognize lease revenue as a combined single lease component for all time charters (operating leases) as the related lease component and non-lease component will have the same timing and pattern of the revenue recognition of the combined single lease component. The performance obligations in a time charter contract are satisfied over the term of the contract beginning when the vessel is delivered to the charterer until it is redelivered back to the Company. As a result of the adoption of these standards, there was no effect on the Company’s opening retained earnings, consolidated balance sheets and consolidated statements of comprehensive (loss)/income.

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 arrives at the loading port, as applicable under the contract, and is deemed to end upon the completion of the discharge of the current cargo. Under a voyage charter, a vessel is provided for the transportation of specific goods between specific ports in return for payment of an agreed upon freight per ton of cargo.

Revenues 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 contracts of affreightment (“COA”)/voyage contracts relating to our barges are recognized ratably over the estimated relative transit time of each voyage. A voyage is deemed to commence upon the barge’s arrival at the loading port, as applicable under the contract, and is deemed to end upon the completion of discharge under the current voyage. The percentage of transit time 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.

Upon adoption of ASC 606, the Company is recognizing revenue ratably from the vessel’s/barge’s arrival at the loading port, as applicable under the contract, to when the charterer’s cargo is discharged as well as defer costs that meet the definition of “costs to fulfill a contract” and relate directly to the contract. The adoption of this standard had no material effect on the Company’s opening retained earnings, consolidated balance sheets and consolidated statements of comprehensive (loss)/income.

Revenues from time chartering and bareboat chartering of vessels and barges 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 or barge 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.

For vessels operating in pooling arrangements, the Company earns a portion of total revenues generated by the pool, net of expenses incurred by the pool. The amount allocated to each pool participant vessel, including the Company’s vessels, is determined in accordance with an agreed-upon formula, which is determined by margins awarded to each vessel in the pool based on the vessel’s age, design and other performance characteristics. Revenue under pooling arrangements is accounted for on the accrual basis and is recognized in the period in which the variability is resolved. The allocation of such net revenue may be subject to future adjustments by the pool, however, such changes are not expected to be material.

Profit-sharing revenues are calculated at an agreed percentage of the excess of the charterer’s average daily income (calculated on a quarterly or half-yearly basis) or the Baltic Dry Index over an agreed amount and accounted for on an accrual basis based on provisional amounts and for those contracts that provisional accruals cannot be made due to the nature of the profit sharing elements, these are accounted for on the actual cash settlement.

Revenues from dry 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 or the stockpiles for temporary storage and then loading the ocean-going vessels. Revenues are recognized upon completion of loading the ocean-going vessels. Revenue arising from contracts that provide our customers with continuous access to port terminal storage and transshipment capacity is recognized ratably over the period of the contracts. 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 as the performance obligation is met evenly over the loading period. Storage fees are assessed and recognized at the point 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 consist mainly of sales of petroleum products in the Paraguayan market and revenues from liquid port operations. Revenues from liquid port terminal operations consist of an agreed flat fee per cubic meter or a fixed rate over a specific period to cover the services performed to unload barges, transfer the products into the tanks for temporary storage and then loading the trucks. Revenues that consist of an agreed flat fee per cubic meter are recognized upon completion of loading the trucks. Revenues from liquid port terminal operations that consist of a fixed rate over a specific period are recognized ratably over the storage period as the performance obligation is met evenly over time, ending when the product is loaded onto the trucks.

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/ (expense), net”.

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 8). 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.

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.

(d)	Recent Accounting Pronouncements:

In October 2018, the Financial Accounting Standards Board (“FASB”) issued ASU 2018-17, Consolidation (Topic 810): “Targeted Improvements to Related Party Guidance for Variable Interest Entities” (“ASU 2018-17”). ASU 2018-17 provides that indirect interests held through related parties in common control arrangements should be considered on a proportional basis for determining whether fees paid to decision makers and service providers are variable interests. This is consistent with how indirect interests held through related parties under common control are considered for determining whether a reporting entity must consolidate a VIE. For public business entities the amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently assessing the impact that adopting this new accounting guidance will have on its disclosures to the consolidated financial statements.

In August 2018, FASB issued ASU 2018-14, “Compensation-Retirement Benefits-Defined Benefit Plans (Topic 715-20): Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans”. This update modifies the disclosure requirements for defined benefit pension plans and other postretirement plans. ASU 2018-14 is effective for public business entities that are SEC filers beginning in the first quarter of fiscal year 2021, and earlier adoption is permitted. The Company is currently assessing the impact that adopting this new accounting guidance will have on its disclosures to the consolidated financial statements.

In August 2018, FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement”. This update modifies the disclosure requirements on fair value measurements. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, and earlier adoption is permitted. The Company is currently assessing the impact that adopting this new accounting guidance will have on its disclosures to the consolidated financial statements.

In January 2017, FASB issued ASU 2017-04, “Intangibles-Goodwill and Other (Topic 350)”. This update addresses concerns expressed about the cost and complexity of the goodwill impairment test and simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. The amendments in this ASU are required for public business entities and other entities that have goodwill reported in their financial statements and have not elected the private company alternative for the subsequent measurement of goodwill. The amendments are effective for public business entities that are SEC filers for fiscal years beginning after December 15, 2019. Early adoption is permitted for all entities. The Company is currently assessing the impact that adopting this new accounting guidance will have on its consolidated financial statements.

In June 2016, FASB issued ASU No. 2016-13, “Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” This standard requires entities to measure all expected credit losses of financial assets held at a reporting date based on historical experience, current conditions, and reasonable and supportable forecasts in order to record credit losses in a more timely manner. ASU 2016-13 also amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The standard is effective for interim and annual reporting periods beginning after December 15, 2019, although early adoption is permitted for interim and annual periods beginning after December 15, 2018. In November 2018, FASB issued ASU 2018-19 “Codification Improvements to topic 326, Financial Instruments-Credit Losses”. The amendments in this update clarify that operating lease receivables are not within the scope of ASC 326-20 and should instead be accounted for under the new leasing standard, ASC 842. In April 2019, FASB issued ASU 2019-04 “Codification Improvements to topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments”. In May 2019, FASB issued ASU 2019-05, “Financial Instruments-Credit Losses (Topic 326): Targeted Transition Relief”. The amendments in this update provide entities that have certain instruments within the scope of Subtopic 326-20, Financial Instruments-Credit Losses-Measured at Amortized Cost, with an option to irrevocably elect the fair value option in Subtopic 825-10, Financial Instruments-Overall, applied on an instrument-by-instrument basis for eligible instruments, upon adoption of Topic 326. The fair value option election does not apply to held-to-maturity debt securities. An entity that elects the fair value option should subsequently apply the guidance in Subtopics 820-10, Fair Value Measurement-Overall, and 825-10. The Company is currently assessing the impact that adopting this new accounting guidance will have on its consolidated financial statements.

Secured Credit Facilities

As of June 30, 2019, the Company had secured credit facilities with various banks with a total outstanding balance of $134,129. The purpose of the facilities was to finance the construction or acquisition of vessels or refinance existing indebtedness. All of the facilities are denominated in U.S. dollars and bear interest based on LIBOR plus spread ranging from 2.75% to 3.60% per annum. The facilities are repayable in either semi-annual or quarterly installments, followed by balloon payments with maturities, ranging from June 2021 to November 2022. See also the maturity table included below.

The facilities are secured by first priority mortgages on certain of Navios Holdings’ vessels and other collateral.

The credit facilities contain a number of restrictive covenants that limit Navios Holdings and/or certain of its subsidiaries from, among other things: incurring or guaranteeing indebtedness; entering into affiliate transactions; charging, pledging or encumbering the vessels securing such facilities; changing the flag, class, management or ownership of certain Navios Holdings’ vessels; changing the commercial and technical management of certain Navios Holdings’ vessels; selling or changing the ownership of certain Navios Holdings’ vessels; and subordinating the obligations under the credit facilities to any general and administrative costs relating to the vessels. The credit facilities also require the vessels to comply with the ISM Code and ISPS Code and to maintain valid safety management certificates and documents of compliance at all times. Additionally, the credit facilities require compliance with the covenants contained in the indentures governing the 2022 Senior Secured Notes (as defined herein), the 2022 Notes (as defined herein) and the 2024 Notes (as defined herein). Among other events, it will be an event of default under the credit facilities if the financial covenants are not complied with or if Angeliki Frangou and her affiliates, together, own less than 20% of the outstanding share capital of Navios Holdings.

The majority of the Company’s senior secured credit facilities require compliance with maintenance covenants, including (i) value-to-loan ratio covenants, based on charter-free valuations, ranging from over 120% to 135%, (ii) minimum liquidity up to a maximum of $30,000, and (iii) net total debt divided by total assets, as defined in each senior secured credit facility, ranging from a maximum of 75% to 80%. Certain covenants in our senior secured credit facilities have been amended for a specific period to increase the covenant levels for the applicable net total debt divided by total assets maintenance covenants, as defined in each senior secured credit facility, to a maximum of 85%.

As of June 30, 2019, the Company was in compliance with all of the covenants under each of its credit facilities.

2022 Senior Secured Notes

On November 21, 2017, the Company and its wholly owned subsidiary, Navios Maritime Finance II (US) Inc. (together with the Company, the “Co-Issuers”) issued $305,000 of 11.25% Senior Notes due 2022 (the “2022 Senior Secured Notes”), at a price of 97%.

The 2022 Senior Secured Notes are secured by a first priority lien on the capital stock owned by certain of the subsidiary guarantors of Navios Holdings in each of Navios Partners, Navios GP L.L.C., Navios Acquisition, Navios Logistics and Navios Containers. In May 2019, the capital stock in Navios Partners and 224,116 Navios Acquisition shares that were collateral under the 2022 Senior Secured Notes were released and replaced by Navios Azimuth. See also Note 15. The 2022 Senior Secured Notes are unregistered and guaranteed by all of the Company’s direct and indirect subsidiaries, except for certain subsidiaries designated as unrestricted subsidiaries, including Navios Logistics. The subsidiary guarantees are “full and unconditional”, except that the indenture provides for an individual subsidiary’s guarantee to be automatically released in certain customary circumstances, such as when a subsidiary is sold or all of the assets of the subsidiary are sold, the capital stock is sold, when the subsidiary is designated as an “unrestricted subsidiary” for purposes of the indenture, upon liquidation or dissolution of the subsidiary or upon legal or covenant defeasance or satisfaction and discharge of the 2022 Senior Secured Notes.

The Co-Issuers have the option to redeem the 2022 Senior Secured Notes in whole or in part, at any time on or after November 16, 2018 at a fixed price of 104.219%, which price declines ratably until it reaches par in November 2019.

The 2022 Senior Secured Notes contain covenants which, among other things, limit the incurrence of additional indebtedness, issuance of certain preferred stock, the payment of dividends, redemption or repurchase of capital stock or making restricted payments and investments, creation of certain liens, transfer or sale of assets, entering in transactions with affiliates, merging or consolidating or selling all or substantially all of the Co-Issuers’ properties and assets and creation or designation of restricted subsidiaries. The Co-Issuers were in compliance with the covenants as of June 30, 2019.

2022 Notes

On November 29, 2013, the Co-Issuers completed the sale of $650,000 of its 7.375% First Priority Ship Mortgage Notes due 2022 (the “2022 Notes”). During September 2018, the Company repurchased $35,661 of its 2022 Notes for a cash consideration of $28,796. During March 2019, Navios Logistics repurchased $31,500 in par value of its 2022 Notes from unaffiliated third parties in open market transactions for a cash consideration of $15,532 resulting in a gain on bond extinguishment of $15,662, net of deferred fees written-off. During April 2019, Navios Logistics repurchased $4,000 in par value of its 2022 Notes from unaffiliated third parties in open market transactions for a cash consideration of $2,110. During May 2019, the Company repurchased $11,000 in par value of its 2022 Notes for a cash consideration of $7,048 resulting in a gain on bond extinguishment of $5,712, net of deferred fees written-off. (Refer to Note 8, “Secured credit facility with Navios Logistics”).

The 2022 Notes are senior obligations of Navios Holdings and Navios Maritime Finance II (US) Inc. (the “2022 Co- Issuers”) and were originally secured by first priority ship mortgages on 23 dry bulk vessels owned by certain subsidiary guarantors and certain other associated property and contract rights. In June 2017, Navios Ionian and Navios Horizon were released from the 2022 Notes and replaced by the Navios Galileo. In March 2018, Navios Herakles was released from the 2022 Notes and replaced by the Navios Equator Prosper. In July 2018, Navios Achilles was released from the 2022 Notes and replaced by the Navios Primavera. In December 2018 and in March 2019, Navios Magellan and Navios Meridian, respectively, were released from the 2022 Notes and the total proceeds of $14,000 were restricted in escrow accounts and considered as cash collaterals. In May 2019 and June 2019, Navios Equator Prosper, Navios Vector and the cash collaterals in escrow accounts were released from the 2022 Notes and replaced by the N Bonanza and N Amalthia and the total proceeds of $7,410 were restricted in an escrow account and considered as cash collateral. In August 2019, the cash collateral in escrow accounts were released from the 2022 Notes and replaced by Navios Victory. The 2022 Notes are unregistered and fully and unconditionally guaranteed, jointly and severally by all of the Company’s direct and indirect subsidiaries, other than Navios Maritime Finance (US) Inc., Navios Logistics and its subsidiaries and Navios GP L.L.C.

The guarantees of the Company’s subsidiaries that own mortgaged vessels are senior secured guarantees and the guarantees of the Company’s subsidiaries that do not own mortgaged vessels are senior unsecured guarantees. In addition, the 2022 Co-Issuers have the option to redeem the 2022 Notes in whole or in part, at any time on or after January 15, 2019, at a fixed price of 101.844%, which price declines ratably until it reaches par in January 2020.

Upon occurrence of certain change of control events, the holders of the 2022 Notes may require the 2022 Co-Issuers to repurchase some or all of the 2022 Notes at 101% of their face amount. The 2022 Notes contain covenants, which among other things, limit the incurrence of additional indebtedness, issuance of certain preferred stock, the payment of dividends, redemption or repurchase of capital stock or making restricted payments and investments, creation of certain liens, transfer or sale of assets, entering into certain transactions with affiliates, merging or consolidating or selling all or substantially all of the 2022 Co-Issuers’ properties and assets and creation or designation of restricted subsidiaries. The indenture governing the 2022 Notes includes customary events of default. The 2022 Co-Issuers were in compliance with the covenants as of June 30, 2019.

2024 Notes

On March 21, 2019, Navios Holdings issued $4,747 of 9.75% Senior Notes due 2024 (the “2024 Notes”) as an exchange for a total of 10,930 Series H which were validly tendered as of that date (Refer to Note 9).

FAIR VALUE OF FINANCIAL INSTRUMENTS [abstract]

FAIR VALUE OF FINANCIAL INSTRUMENTS

NOTE 6: 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 book value has been adjusted to reflect the net presentation of deferred financing costs. The outstanding balance of the floating rate loans continues to approximate its fair value, excluding the effect of any deferred finance costs. The 2022 Notes, the 2022 Logistics Senior Notes, the 2022 Senior Secured Notes, two Navios Logistics’ loans and the Navios Containers’ seller’s credit are fixed rate borrowings and their fair value was determined based on quoted market prices.

Loan receivable from affiliate companies: The carrying amount of the floating rate loan 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 in the consolidated statements of comprehensive (loss)/income.

Long-term payable to affiliate companies: The carrying amount of long-term payable to affiliate companies approximates their fair value.

The estimated fair values of the Company’s financial instruments are as follows:

The estimated fair value of our financial instruments that are not measured at fair value on a recurring basis, categorized based upon the fair value hierarchy, are as follows:

Level I: Inputs are unadjusted, quoted prices for identical assets or liabilities in active markets that we have the ability to access. Valuation of these items does not entail a significant amount of judgment.

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

Level III: Inputs that are unobservable.

EARNINGS/ (LOSS) PER COMMON SHARE [Abstract]

EARNINGS/ (LOSS) PER COMMON SHARE

NOTE 12: EARNINGS/ (LOSS) PER COMMON SHARE

Earnings/(loss) per share is calculated by dividing net loss attributable to Navios Holdings common stockholders by the weighted average number of shares of Navios Holdings outstanding during the periods presented. Net (loss)/income attributable to Navios Holdings common stockholders is calculated by adding to (if a discount) or deducting from (if a premium) net (loss)/ income attributable to Navios Holdings common stockholders the difference between the fair value of the consideration paid upon redemption and the carrying value of the preferred stock, including the unamortized issuance costs of the preferred stock, and the amount of any undeclared dividend cancelled.

For the three month period ended June 30, 2019, 861,158 potential common shares and 349,900 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 three month period ended June 30, 2018, 701,482 potential common shares and 349,900 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 six month period ended June 30, 2019, 834,394 potential common shares and 349,900 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 six month period ended June 30, 2018, 663,397 potential common shares and 349,900 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.

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 April 25, 2019, Navios Partners announced a 1-for-15 reverse stock split of its issued and outstanding shares of common units and general partners units. The reverse stock split was effective on May 21, 2019. All issued and outstanding shares of common units and general partner units contained to the notes to the consolidated financial statements until May 21, 2019, are presented before reverse stock split.

Navios Europe I

On December 18, 2013, Navios Europe I acquired ten vessels for aggregate consideration consisting of (i) cash (which was funded with the proceeds of senior loan facilities (the “Senior Loans I”) and loans aggregating to $10,000 from Navios Holdings, Navios Acquisition and Navios Partners (in each case, in proportion to their economic interests in Navios Europe I) (collectively, the “Navios Term Loans I”) and (ii) the assumption of a junior participating loan facility (the “Junior Loan I”). In addition to the Navios Term Loans I, Navios Holdings, Navios Acquisition and Navios Partners will also make available to Navios Europe I revolving loans up to $24,100 to fund working capital requirements (collectively, the “Navios Revolving Loans I”). The Navios Term Loans I will be repaid from the future sale of vessels owned by Navios Europe I. In December 2018, the amount of the Navios Revolving Loans I increased by $30,000.

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

Navios Holdings evaluated its investment in Navios Europe I under ASC 810 and concluded that Navios Europe I is a VIE and that it is not the party most closely associated with Navios Europe I and, accordingly, is not the primary beneficiary of Navios Europe I.

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

The initial amount provided for in Navios Europe I of $4,750 at the inception included the Company’s share of the basis difference between the fair value and the underlying book value of the assets of Navios Europe I, which amounted to $6,763.

In addition to the Navios Term Loans II, Navios Holdings, Navios Acquisition and Navios Partners will also make available to Navios Europe II revolving loans up to $43,500 to fund working capital requirements (collectively, the “Navios Revolving Loans II”). The Navios Term Loans II will be repaid from the future sale of vessels owned by Navios Europe II. In March 2017, the amount of the Navios Revolving Loans II increased by $14,000.

On an ongoing basis, Navios Europe II is required to distribute cash flows (after payment of operating expenses, amounts due pursuant to the terms of the Senior Loans II) according to a defined waterfall calculation.

Leases

LEASES [Abstract]

LEASES

NOTE 14: LEASES

On January 1, 2019, the Company adopted ASC 842. ASC 842 revises the accounting for leases. Under the new lease standard, lessees are required to recognize a right-of-use asset and a lease liability for substantially all leases. The new lease standard will continue to classify leases as either financing or operating, with classification affecting the pattern of expense recognition. The accounting applied by a lessor under the new guidance will be substantially equivalent to current lease accounting guidance.

The following are the type of contracts that fall under ASC 842:

Time charter out contracts

The Company’s contract revenues from time chartering are governed by ASC 842. Upon adoption of ASC 842, the timing and recognition of earnings from the time charter contracts to which the Company is party did not change from previous practice. In a time charter contract, the Company is responsible for all the costs incurred for running the vessel such as crew costs, vessel insurance, repairs and maintenance and lubes. The charterer bears the voyage related costs such as bunker expenses, port charges and canal tolls

during the hire period. The Company has determined to recognize lease revenue as a combined single lease component for all time charters (operating leases) as the related lease component and non-lease component will have the same timing and pattern of the revenue recognition of the combined single lease component. The performance obligations in a time charter contract are satisfied over the term of the contract beginning when the vessel is delivered to the charterer until it is redelivered back to the Company. The Company determined that all time charter contracts are considered operating leases and therefore fall under the scope of ASC 842 because: (i) the vessel is an identifiable asset; (ii) the Company does not have substantive substitution rights; and (iii) the charterer has the right to control the use of the vessel during the term of the contract and derives the economic benefits from such use.

The transition guidance associated with ASC 842 allows for certain practical expedients to the lessors. The Company elected to not separate the lease and non-lease components included in the time charter revenue because (i) the pattern of revenue recognition for the lease and non-lease components (included in the daily hire rate) is the same. The daily hire rate represents the hire rate for a bare boat charter as well as the compensation for expenses incurred running the vessel such as crewing expense, repairs, insurance, maintenance and lubes. Both the lease and non-lease components are earned by passage of time.

As a result of the adoption of these standards, there was no effect on the Company’s opening retained earnings, consolidated balance sheets and consolidated statements of comprehensive (loss)/income.

Time charter in contracts

As of June 30, 2019, Navios Holdings had time charter-in contracts whose remaining lease terms ranged from 0.1 years to 7.1 years. Certain operating leases have optional periods. Based on management estimates and market conditions, the lease term of these leases is being assessed at each balance sheet date. Regarding leases that have not yet commenced refer to Note 7. The Company will continue to recognize the lease payments for all operating leases as charter hire expense on the consolidated statements of comprehensive (loss)/income on a straight-line basis over the lease term.

Land lease agreements

As of June 30, 2019, Navios Logistics had land lease agreements whose remaining lease terms range from 46.7 years to 47.1 years.

Office lease agreements

As of June 30, 2019, Navios Holdings and Navios Logistics had office lease agreements whose remaining lease terms ranged from 0.3 years to 15.4 years and from 0.7 years to 4.3 years, respectively.

Under ASC 842, leases are classified as either finance or operating arrangements, with such classification affecting the pattern and classification of expense recognition in an entity’s income statement. For operating leases, ASC 842 requires recognition in an entity’s income statement of a single lease expense, calculated so that the cost of the lease is allocated over the lease term, generally on a straight-line basis. Right-of-use assets represent a right to use an underlying asset for the lease term and the related lease liability represents an obligation to make lease payments pursuant to the contractual terms of the lease agreement.

In connection with its adoption of ASC 842, the Company elected the “package of 3” practical expedients permitted under the transition guidance based on which the Company is allowed to not (i) reassess whether any expired or existing contracts are considered or contain leases; (ii) reassess the lease classification for any expired or existing leases; and (iii) reassess initial direct costs for any existing leases.

Additionally, the Company elected the practical expedient allowed under the transition guidance of ASC 842 to not separate the lease and non-lease components related to a lease contract and to account for them as a single lease component for the purposes of the recognition and measurement requirements of ASC 842.

Prior to January 1, 2019, the Company recognized lease expense in accordance with then-existing U.S. GAAP (“prior GAAP”). Because both ASC 842 and prior GAAP generally recognize operating lease expense on a straight-line basis over the term of the lease arrangement and the Company only has operating lease arrangements, there were no differences between the timing and amount of lease expense recognized under the two accounting methodologies.

(1)	On January 1, 2019, operating lease assets were adjusted for $14,184 representing the balance of the carrying amount of the liabilities regarding straight line and the provision for losses on the time charters and voyages in progress recognized in the consolidated balance sheet as of December 31, 2018.
(2)	Based on the net present value of the remaining charter-in and rental payments for existing operating leases.

At lease commencement, the Company determines a discount rate to calculate the present value of the lease payments so that it can determine lease classification and measure the lease liability. In determining the discount rate to be used at lease commencement, the Company used its incremental borrowing rate as there was no implicit rate included in charter-in contracts and office lease agreements that can be readily determinable. The incremental borrowing rate is the rate that reflects the interest a lessee would have to pay to borrow funds on a collateralized basis over a similar term and in a similar economic environment. The Company then applied the respective incremental borrowing rates to each lease based on the remaining lease term of the specific lease. Navios Holdings’ and Navios Logistics’ incremental borrowing rates upon adoption were 8.25% and 7.25%, respectively. As of June 30, 2019, Navios Holdings’ incremental borrowing rate was 8.29%.

SUBSEQUENT EVENTS [Abstract]
SUBSEQUENT EVENTS	NOTE 15: SUBSEQUENT EVENTS a) In August 2019, Navios Holdings announced that it sold its ship management division and certain general partnership interests (the “Transaction”) to N Shipmanagement Acquisition Corp. and related entities (“NSAC”), affiliated with Company’s Chairman and Chief Executive Officer, Angeliki Frangou. The Company received aggregate consideration of $20,000 (including assumption of liabilities) and new five-year service agreements under which NSAC will provide technical and commercial management services at fixed rates (as described below) and administrative services, reimbursed at allocable cost. As a result of the Transaction: The Company is a holding company owning dry bulk vessels and various investments in entities owning maritime and infrastructure assets. NSAC owns all entities providing ship management services and employs all associated people. The Company will pay a fixed rate of $3.7 per day per vessel, which will cover all technical and commercial management services and operating costs, other than dry-docking and special surveys. This rate will be fixed for a two-year period and will increase thereafter by 3% annually. NSAC will provide all administrative services to the Company and will be reimbursed at allocable cost. NSAC will own the general partner interests in Navios Containers and Navios Partners. The Company will deconsolidate Navios Containers from August 30, 2019 onwards. NSAC entered into: a management agreement with Navios Acquisition whereby Navios Tankers Management Inc. (“Tankers Management”) agreed to provide commercial and technical management services to Navios Acquisition’s vessels (i) for a fixed daily fee of $6.5 per MR2 product tanker and chemical tanker vessel, $7.15 per LR1 product tanker vessel and $9.5 per VLCC through December 31, 2019; (ii) for a fixed daily fee of $6.8 per MR2 product tanker and chemical tanker vessel, $7.2 per LR1 product tanker vessel and $9.65 per VLCC for two years commencing on January 1, 2020; (iii) a 3% annual increase thereafter of the fixed daily fee through January 1, 2025; and (iv) a technical and management daily fee of $0.1 per vessel, through January 1, 2025. Drydocking expenses will be reimbursed by Navios Acquisition at cost at occurrence. The term of this agreement is until January 1, 2025 and shall be automatically renewed for a period of five years. a management agreement with Navios Partners whereby Navios Shipmanagement Inc. (“NSM”) agreed to provide commercial and technical management services to Navios Partners’ vessels (i) for a fixed daily fee of $4.2 daily rate per Ultra-Handymax vessel, $4.3 daily rate per Panamax vessel, $5.25 daily rate per Capesize vessel and $6.7 daily rate per container vessel of TEU 6,800 through December 31, 2019; (ii) for a fixed daily fee of $4.35 daily rate per Ultra-Handymax vessel, $4.45 daily rate per Panamax vessel, $5.4 daily rate per Capesize vessel and $6.9 daily rate per container vessel of TEU 6,800 for two years commencing on January 1, 2020; (iii) a 3% annual increase thereafter of the fixed daily fee through January 1, 2025; and (iv) a technical and management daily fee of $0.1 per vessel, through January 1, 2025. Drydocking expenses will be reimbursed by Navios Partners at cost at occurrence. The term of this agreement is until January 1, 2025 and shall be automatically renewed for a period of five years. a management agreement with Navios Containers whereby NSM agreed to provide commercial and technical management services to Navios Containers’ vessels (i) for a fixed daily fee of $6.1 per day for up to 5,500 TEU container vessels, $6.7 per day for above 5,500 TEU and up to 8,000 TEU container vessels and $7.4 per day for above 8,000 TEU and up to 10,000 TEU container vessels through December 31, 2019; (ii) for a fixed daily fee of $6.3 per day for up to 5,500 TEU container vessels, $7.8 per day for above 5,500 TEU and up to 8,000 TEU container vessels and $8.3 per day for above 8,000 TEU and up to 10,000 TEU container vessels for two years commencing on January 1, 2020; (iii) a 3% annual increase thereafter of the fixed daily fee through January 1, 2025; and (iv) a technical and management daily fee of $0.1 per vessel, through January 1, 2025. Drydocking expenses will be reimbursed by Navios Partners at cost at occurrence. The term of this agreement is until January 1, 2025 and shall be automatically renewed for a period of five years. an administrative agreement with Navios Logistics whereby the administrative services agreement originally entered into between Navios Logistics and the Company on April 12, 2011, first assigned to Navios Corporation (“NC”) on May 28, 2014 and subsequently amended on April 6, 2016 (extending the duration of the agreement until December 2021), was assigned from NC to NSM. Thereafter NSM will continue to provide certain administrative management services to Navios Logistics. NSM will be reimbursed for reasonable costs and expenses incurred in connection with the provision of these services. an administrative agreement with Navios Acquisition whereby Tankers Management provides administrative services to Navios Acquisition. Tankers Management extended the duration of its existing administrative services agreement with Navios Acquisition until January 1, 2025, to be automatically renewed for a period of five years, pursuant to its existing terms. an administrative agreement with Navios Partners whereby NSM provides administrative services to Navios Partners.

The Company simultaneously entered into a secured loan agreement with NSAC whereby the Company agreed to repay NSAC $125,000 (subject to post-closing adjustment) over a five-year period. In general, the amount owed reflects the excess of (i) the liabilities of the ship management business (including liabilities for advances previously made by affiliates to the Company for ongoing operating costs, including technical management services, supplies, dry-docking and related expenses) other than liabilities the assumption of which forms part of the consideration for the Transaction over (ii) the short term assets of the ship management business. Of the amount owed, $47,000 will be repayable during the first 12 months in equal quarterly installments, with the remaining principal amount repayable in equal quarterly installments over the following 48 months. In certain cases, amortization can be deferred. The loan agreement provides for interest at 5% annually, and 7% annually for deferred principal amounts. The closing of the Transaction occurred simultaneously with the execution of the definitive transaction agreements. The Company’s Board of Directors formed a Special Committee of independent and disinterested directors to consider the Transaction. The Special Committee, with the assistance of its independent financial and legal advisors, exclusively negotiated the terms of the transaction agreements and approved the transaction on behalf of the Board of Directors. Pareto Securities AS acted as financial advisor and Debevoise & Plimpton LLP acted as legal counsel to the Special Committee b) In August 2019, Navios Holdings acquired from an unrelated third party, a previously chartered-in vessel, Navios Victory, a 2014 built, 77,095 dwt vessel, for a total acquisition price of $14,500 which was paid in cash. c) In July 2019, the Company agreed to sell to an unrelated third party the Navios Primavera, a 2007-built Ultra Handymax vessel of 53,464 dwt, for a total net sale price of $9,891, to be paid in cash, with delivery expected in September 2019. The loss due to sale is expected to be approximately $1,673. d) In July 2019, Navios Containers converted the obligation to purchase a 2011-built 10,000 TEU containership, into an option, expiring on March 31, 2020. The agreement grants Navios Containers the option and the right of first refusal to acquire the vessel at terms mutually agreed with the seller. In case Navios Containers does not exercise the option and the containership is not sold to a third party by March 31, 2020, Navios Containers will be required to make a payment of $3,000 to the sellers.
