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, 2017 filed on Form 20-F with the Securities and Exchange Commission (“SEC”). Change in accounting principles: ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash The Company historically presented changes in restricted cash and cash equivalents depending on the nature of the cash flow within the consolidated statement of cash flows. During the first quarter of 2018, the Company adopted ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash , which requires that restricted cash and restricted cash equivalents be included as components of total cash and cash equivalents as presented on the statement of cash flows. The recognition and measurement guidance for restricted cash is not affected. The Company applied this guidance retrospectively to all prior periods presented in the Company’s financial statements. The effect of the retrospective application of this change in accounting principle on the Company’s statement of cash flows for the six months ended June 30, 2017 resulted in a decrease of cash provided by operating activities in the amount of $2,899 and a decrease of cash used in financing activities in the amount of $1,976 with a corresponding decrease in cash and cash equivalents and restricted cash of $923. The following table provides a reconciliation of cash and cash equivalents and restricted cash to amounts reported within the condensed consolidated balance sheets: June 30, 2018 December 31, 2017 Reconciliation of cash, cash equivalents and restricted cash: Current assets: Cash and cash equivalents 118,454 127,632 Restricted cash 2,978 6,558 Total cash and cash equivalents and restricted cash $ 121,432 $ 134,190 ASC 606, Revenue from Contracts with Customers (“ASC 606”) On January 1, 2018, the Company adopted the provisions of ASC 606, Revenue from Contracts with Customers . 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. 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 continue to be governed by ASC 840 Leases . Upon adoption of ASC 606, the timing and recognition of earnings from time charter contracts to which the Company is party did not change from previous practice. (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, which is 63.8% owned. 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, 2018 was 20.2%, which includes a 2.0% general partner interest); (ii) Navios Acquisition and its subsidiaries (economic interest as of June 30, 2018 was 48.3%); (iii) Acropolis Chartering and Shipping Inc. (“Acropolis”) (economic interest as of June 30, 2018 was 35.0%), (iv) Navios Europe I and its subsidiaries (economic interest as of June 30, 2018 was 47.5%); (v) Navios Europe II and its subsidiaries (economic interest as of June 30, 2018 was 47.5%); and (vi) Navios Containers and its subsidiaries (economic interest as of June 30, 2018 was 3.1%). (c) 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 were previously recognized ratably over the estimated relative transit time of each voyage. A voyage was deemed to commence when a vessel arrives at the loading port, as applicable under the contract, and was 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 were previously recognized ratably over the estimated relative transit time of each voyage. A voyage was deemed to commence upon the barge’s arrival at the loading port, as applicable under the contract, and was deemed to end upon the completion of discharge under the current voyage. The percentage of transit time was 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 was 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 was 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 will recognize 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 earned under contracts of affreightment (“COA”)/voyage contracts within the Dry Bulk Vessel Operations, amounted to $5,998 and $9,629 for the three month period ended June 30, 2018 and 2017, respectively and $14,617 and $19,288 for the six month periods ended June 30, 2018 and 2017, respectively. Revenues earned under contracts of affreightment (“COA”)/voyage contracts within the Logistics business, amounted to $10,623 and $13,145 for the three month period ended June 30, 2018 and 2017, respectively and $19,552 and $23,451 for the six month periods ended June 30, 2018 and 2017, respectively. 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. Revenues from time chartering of vessels in the Dry Bulk Vessel Operations amounted to $66,427 and $46,430 for the three month period ended June 30, 2018 and 2017, respectively and $122,161 and $83,725 for the six month periods ended June 30, 2018 and 2017, respectively. Revenues from time chartering and bareboat chartering of vessels and barges in the Logistics business amounted to $17,988 and $23,443 for the three month period ended June 30, 2018 and 2017, respectively and $36,534 and $41,350 for the six month periods ended June 30, 2018 and 2017, respectively. For vessels operating in pooling arrangements, the Company earns a portion of total revenues generated by the pool, net of expenses incurred by the pool. The amount allocated to each pool participant vessel, including the Company’s vessels, is determined in accordance with an agreed-upon formula, which is determined by 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. Revenue for vessels operating in pooling arrangements in the Dry Bulk Vessel Operations amounted to $0 and $2,792 for the three month period ended June 30, 2018 and 2017, respectively and $0 and $7,133 for the six month periods ended June 30, 2018 and 2017, respectively. Profit-sharing revenues are calculated at an agreed percentage of the excess of the charterer’s average daily income (calculated on a quarterly or half-yearly basis) or the Baltic Dry Index over an agreed amount and accounted for on an accrual basis based on provisional amounts and for those contracts that provisional accruals cannot be made due to the nature of the profit sharing elements, these are accounted for on the actual cash settlement. Profit sharing results from the Dry Bulk Vessel Operations for the three month period ended June 30, 2018 and 2017 amounted to $(339) and $300, respectively and for the six month periods ended June 30, 2018 and 2017 amounted to $(205) and $445, respectively. 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. Revenue from port terminal operations of the Logistics business amounted to $20,201 and $11,895 for the three month period ended June 30, 2018 and 2017, respectively and $34,591 and $17,609 for the six month periods ended June 30, 2018 and 2017, respectively. Revenues from storage fees (dry port) of the Logistics business amounted to $74 and $329 for the three month period ended June 30, 2018 and 2017, respectively and $341 and $699 for the six month periods ended June 30, 2018 and 2017, respectively. Dockage revenues from the Logistics business in the dry port terminal operations amounted to $923 and $1,198 for the three month period ended June 30, 2018 and 2017, respectively and $1,530 and $1,854 for the six month periods ended June 30, 2018 and 2017, respectively. 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. Revenues from sale of products by the Logistics business amounted to $9,265 and $8,810 for the three month period ended June 30, 2018 and 2017, respectively and $17,690 and $16,822 for the six month periods ended June 30, 2018 and 2017, respectively. Revenues from liquid port terminal operations from the Logistics business amounted to $860 and $548 for the three month periods ended June 30, 2018 and 2017, respectively and $1,858 and $1,283 for the six month periods ended June 30, 2018 and 2017, respectively. 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. 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. 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. The Company has not entered into FFA trades for any of the periods presented. 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 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 January 2017, FASB issued ASU 2017-03, “Accounting Changes and Error Corrections (Topic 250) and Investments-Equity Method and Joint Ventures (Topic 323)”. The ASU amends the Codification for SEC staff announcements made at recent Emerging Issues Task Force (EITF) meetings. The SEC guidance that specifically relates to our consolidated financial statements was from the September 2016 meeting, where the SEC staff expressed their expectations about the extent of disclosures registrants should make about the effects of the new FASB guidance as well as any amendments issued prior to adoption, on revenue (ASU 2014-09), leases (ASU 2016-02) and credit losses on financial instruments (ASU 2016-13) in accordance with SAB Topic 11.M. Registrants are required to disclose the effect that recently issued accounting standards will have on their financial statements when adopted in a future period. In cases where a registrant cannot reasonably estimate the impact of the adoption, then additional qualitative disclosures should be considered. The ASU incorporates these SEC staff views into ASC 250 and adds references to that guidance in the transition paragraphs of each of the three new standards. The adoption of this ASU did not have a material effect on the Company’s 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. The Company is currently assessing the impact that adopting this new accounting guidance will have on its consolidated financial statements. In February 2016, FASB issued ASU 2016-02, “Leases (Topic 842)”. ASU 2016-02 will apply to both capital (or finance) leases and operating leases. According to ASU 2016-02, lessees will be required to recognize assets (right of use asset) and liabilities (lease liabilities) on the balance sheet for both types of leases, capital (or finance) leases and operating leases, with terms greater than 12 months. ASU 2016 – 02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted. This guidance requires companies to identify lease and non-lease components of a lease agreement. Lease components relate to the right to use the leased asset and non-lease components relate to payments for goods or services that are transferred separately from the right to use the underlying asset. Total lease consideration is allocated to lease and non-lease components on a relative standalone basis. The recognition of revenues related to lease components will be governed by ASC 842 while revenue related to non-lease components will be subject to ASC 606. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842 Leases (“ASU 2018-10”). The amendments in ASU 2018-10 affect narrow aspects of the guidance issued in the amendments in ASU 2016-02. The amendments in this Update affect the amendments in Update 2016-02, which are not yet effective, but for which early adoption upon issuance is permitted. For entities that early adopted Topic 842, the amendments are effective upon issuance of this Update, and the transition requirements are the same as those in Topic 842. For entities that have not adopted Topic 842, the effective date and transition requirements will be the same as the effective date and transition requirements in Topic 842. In addition, in July 2018, the FASB issued ASU 2018-11, Targeted Improvements to Topic 842 Leases (“ASU 2018-11). The improvements in ASU 2018-11 provide for (a) an optional new transition method for adoption that results in initial recognition of a cumulative effect adjustment to retained earnings in the year of adoption and (b) a practical expedient for lessors, under certain circumstances, to combine the lease and non-lease components of revenues for presentation purposes. ASC 842 provides practical expedients that allow entities to not (i) reassess whether any expired or existing contracts are considered or contain leases; (ii) reassess the lease classification for any expired or existing leases; and (iii) reassess initial direct costs for any existing leases. The Company plans to adopt the standard on January 1, 2019 and expects to elect the use of practical expedients. The Company intends to apply the alternative transition method for adoption as described above. Based on a preliminary assessment, the Company expects the adoption of this guidance to have a material impact on its assets and liabilities due to its charter-in contracts and the recognition of right-of-use assets and lease liabilities on its consolidated balance sheets although adoption is not expected to significantly change the recognition, measurement or presentation of lease expenses within the statements of comprehensive (loss)/income or cash flows. With regards to the Company’s charter-out contracts, the Company is not expecting that the adoption will have a material effect on its consolidated financial statements since the Company is a lessor for these charter-out contracts and the changes are fairly minor. The Company expects to elect the use of practical expedient available to lessors which allows good and services embedded in the charter-out contract that qualify as non-lease components to be combined under a single lease component presentation. The Company is continuing its assessment of other miscellaneous leases, which have lease terms greater than 12 months and the Company is the lessee and may identify additional impacts this guidance will have on the consolidated financial statements and disclosures.

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 Senior Secured Notes, the 2022 Notes, the 2022 Logistics Senior Notes and one Navios Logistics’ loan 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. Long-term payable to affiliate companies: The carrying amount of the long-term payable 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 the consolidated statements of comprehensive (loss)/income at each reporting period. The estimated fair values of the Company’s financial instruments are as follows: June 30, 2018 December 31, 2017 Book Value Fair Value Book Value Fair Value Cash and cash equivalents $ 118,454 $ 118,454 $ 127,632 $ 127,632 Restricted cash $ 2,978 $ 2,978 $ 6,558 $ 6,558 Investments in available-for-sale-securities $ 211 $ 211 $ 238 $ 238 Loan receivable from affiliate companies $ 31,588 $ 31,588 $ 30,112 $ 30,112 Senior and ship mortgage notes, net $ (1,304,608) $ (1,148,252) $ (1,301,999 ) $ (1,181,838 ) Long-term debt, including current portion $ (362,012) $ (368,410) $ (380,489 ) $ (389,332 ) Long term payable to affiliate companies $ (87,422) $ (87,422) $ (76,872 ) $ (76,872 ) The following table sets forth our assets that are measured at fair value on a recurring basis categorized by fair value hierarchy level.

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.

On December 20, 2016, a London arbitration tribunal ruled that the Vale port contract remains in full force and effect. If Vale were to further repudiate or renounce the contract, we may elect to terminate the contract and then would be entitled to damages calculated by reference to guaranteed volumes and agreed tariffs for the remaining period of the contract.

Pursuant to the Partners Omnibus Agreement, Navios Partners generally agreed not to acquire or own Panamax or Capesize dry bulk carriers under time charters of three or more years without the consent of an independent committee of Navios Partners. In addition, Navios Holdings has agreed to offer to Navios Partners the opportunity to purchase vessels from Navios Holdings when such vessels are fixed under time charters of three or more years. Navios Holdings entered into an omnibus agreement with Navios Acquisition and Navios Partners (the “Acquisition Omnibus Agreement”) in connection with the closing of Navios Acquisition’s initial vessel acquisition, pursuant to which, among other things, Navios Holdings and Navios Partners agreed not to acquire, charter-in or own liquid shipment vessels, except for container vessels and vessels that are primarily employed in operations in South America, without the consent of an independent committee of Navios Acquisition. In addition, Navios Acquisition, under the Acquisition Omnibus Agreement, agreed to cause its subsidiaries not to acquire, own, operate or charter dry bulk carriers subject to specific exceptions. Under the Acquisition Omnibus Agreement, Navios Acquisition and its subsidiaries granted to Navios Holdings and Navios Partners, a right of first offer on any proposed sale, transfer or other disposition of any of its dry bulk carriers and related charters owned or acquired by Navios Acquisition. Likewise, Navios Holdings and Navios Partners agreed to grant a similar right of first offer to Navios Acquisition for any liquid shipment vessels it might own. These rights of first offer will not apply to a (i) sale, transfer or other disposition of vessels between any affiliated subsidiaries, or pursuant to the terms of any charter or other agreement with a counterparty, or (ii) merger with or into, or sale of substantially all of the assets to, an unaffiliated third party.

The option shall expire on November 18, 2024. The purchase price for the acquisition for all or part of the option interest shall be an amount equal to its fair market value. As of June 30, 2018, Navios Holdings had not exercised any part of that option. Sale of vessels and sale of rights to Navios Partners: Upon the sale of vessels to Navios Partners, Navios Holdings recognizes the gain immediately in earnings only to the extent of the interest in Navios Partners owned by third parties and defers recognition of the gain to the extent of its own ownership interest in Navios Partners (the “deferred gain”). Subsequently, the deferred gain is amortized to income over the remaining useful life of the vessel. The recognition of the deferred gain is accelerated in the event that (i) the vessel is subsequently sold or otherwise disposed of by Navios Partners or (ii) the Company’s ownership interest in Navios Partners is reduced. In connection with the public offerings of common units by Navios Partners, a pro rata portion of the deferred gain is released to income upon dilution of the Company’s ownership interest in Navios Partners.

LOSS PER COMMON SHARE [Abstract]
LOSS PER COMMON SHARE	NOTE 12: LOSS PER COMMON SHARE 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, 2018, 7,014,824 potential common shares and 3,499,000 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. For the three month period ended June 30, 2017, 5,136,726 potential common shares and 5,625,370 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.

SUBSEQUENT EVENTS [Abstract]
SUBSEQUENT EVENTS	NOTE 14: SUBSEQUENT EVENTS On July 3, 2018, Navios Holdings completed the sale to an unrelated party of the Navios Achilles, a 2001-built, 52,063 dwt vessel, for a total net sale price of $8,085 paid in cash (see note 3). In July 2018, Navios Achilles was released from the 2022 Notes and the gross sale proceeds received serve as collateral to the 2022 Notes, until the replacement with another vessel is completed. In July 2018, Navios Holdings agreed to sell the Navios Mars, a 2016-built Capesize vessel of 181,259 dwt, and the Navios Sphera, a 2016-built Panamax vessel of 84,872 dwt, to its affiliate, Navios Partners for a sale price of $79,000. Part of the sale proceeds will be used for the full prepayment of the outstanding bank debt of the two vessels, while the remaining amount of the sale proceeds will be cash on the Company’s balance sheet. The vessels are expected to be delivered to Navios Partners within the third quarter of 2018. In August 2018, Navios Holdings exercised the option to acquire Navios Primavera, a 2007-built, 53,464 dwt chartered-in vessel for an estimated purchase price of approximately $10,479 to be determined on the actual delivery date of the vessel, which is expected within the fourth quarter of 2018. Upon signing of the contract, Navios Holdings paid an amount of $1,063, while the remaining amount of the acquisition price will be paid upon delivery of the vessel. In August 2018, Navios Holdings agreed to charter-in, under one ten-year bareboat contract, from an unrelated third party one newbuilding bulk carrier of about 81,000 dwt, expected to be delivered in the second quarter of 2020. Navios Holdings has agreed to pay in total $5,820, representing a deposit for the option to acquire this vessel. The transaction is subject to definitive documentation. On August 16, 2018, there was a fire incident at the iron ore port terminal in Nueva Palmira, Uruguay. The fire damaged some equipment, but fortunately there were no human casualties. While it is too early to give a concrete estimate for time required to repair or replace equipment, Navios Logistics maintains property and loss of earnings insurance coverage for such type of events (subject to applicable deductibles and other customary limitations). On August 17, 2018, a new river and estuary tanker was delivered to Navios Logistics. Pursuant to this acquisition Navios Logistics entered into a credit agreement with the shipbuilder for an amount of $7,222 (€6,200) to finance the 50% of the purchase price of the tanker vessel. The credit agreement bears interest at a fixed rate of 675 basis points and is repayable in 24 equal monthly installments.

Summary of Significant Accoun21

Summary of Significant Accounting Policies (Policies)	6 Months Ended

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]
Basis of presentation	(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, 2017 filed on Form 20-F with the Securities and Exchange Commission (“SEC”).
Change in accounting principles	Change in accounting principles: ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash The Company historically presented changes in restricted cash and cash equivalents depending on the nature of the cash flow within the consolidated statement of cash flows. During the first quarter of 2018, the Company adopted ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash , which requires that restricted cash and restricted cash equivalents be included as components of total cash and cash equivalents as presented on the statement of cash flows. The recognition and measurement guidance for restricted cash is not affected. The Company applied this guidance retrospectively to all prior periods presented in the Company’s financial statements. The effect of the retrospective application of this change in accounting principle on the Company’s statement of cash flows for the six months ended June 30, 2017 resulted in a decrease of cash provided by operating activities in the amount of $2,899 and a decrease of cash used in financing activities in the amount of $1,976 with a corresponding decrease in cash and cash equivalents and restricted cash of $923. The following table provides a reconciliation of cash and cash equivalents and restricted cash to amounts reported within the condensed consolidated balance sheets: June 30, 2018 December 31, 2017 Reconciliation of cash, cash equivalents and restricted cash: Current assets: Cash and cash equivalents 118,454 127,632 Restricted cash 2,978 6,558 Total cash and cash equivalents and restricted cash $ 121,432 $ 134,190 ASC 606, Revenue from Contracts with Customers (“ASC 606”) On January 1, 2018, the Company adopted the provisions of ASC 606, Revenue from Contracts with Customers . 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. 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 continue to be governed by ASC 840 Leases . Upon adoption of ASC 606, the timing and recognition of earnings from time charter contracts to which the Company is party did not change from previous practice.
Principles of Consolidation	(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, which is 63.8% owned. 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, 2018 was 20.2%, which includes a 2.0% general partner interest); (ii) Navios Acquisition and its subsidiaries (economic interest as of June 30, 2018 was 48.3%); (iii) Acropolis Chartering and Shipping Inc. (“Acropolis”) (economic interest as of June 30, 2018 was 35.0%), (iv) Navios Europe I and its subsidiaries (economic interest as of June 30, 2018 was 47.5%); (v) Navios Europe II and its subsidiaries (economic interest as of June 30, 2018 was 47.5%); and (vi) Navios Containers and its subsidiaries (economic interest as of June 30, 2018 was 3.1%).
Revenue Recognition	(c) 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 were previously recognized ratably over the estimated relative transit time of each voyage. A voyage was deemed to commence when a vessel arrives at the loading port, as applicable under the contract, and was 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 were previously recognized ratably over the estimated relative transit time of each voyage. A voyage was deemed to commence upon the barge’s arrival at the loading port, as applicable under the contract, and was deemed to end upon the completion of discharge under the current voyage. The percentage of transit time was 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 was 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 was 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 will recognize 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 earned under contracts of affreightment (“COA”)/voyage contracts within the Dry Bulk Vessel Operations, amounted to $5,998 and $9,629 for the three month period ended June 30, 2018 and 2017, respectively and $14,617 and $19,288 for the six month periods ended June 30, 2018 and 2017, respectively. Revenues earned under contracts of affreightment (“COA”)/voyage contracts within the Logistics business, amounted to $10,623 and $13,145 for the three month period ended June 30, 2018 and 2017, respectively and $19,552 and $23,451 for the six month periods ended June 30, 2018 and 2017, respectively. 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. Revenues from time chartering of vessels in the Dry Bulk Vessel Operations amounted to $66,427 and $46,430 for the three month period ended June 30, 2018 and 2017, respectively and $122,161 and $83,725 for the six month periods ended June 30, 2018 and 2017, respectively. Revenues from time chartering and bareboat chartering of vessels and barges in the Logistics business amounted to $17,988 and $23,443 for the three month period ended June 30, 2018 and 2017, respectively and $36,534 and $41,350 for the six month periods ended June 30, 2018 and 2017, respectively. For vessels operating in pooling arrangements, the Company earns a portion of total revenues generated by the pool, net of expenses incurred by the pool. The amount allocated to each pool participant vessel, including the Company’s vessels, is determined in accordance with an agreed-upon formula, which is determined by 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. Revenue for vessels operating in pooling arrangements in the Dry Bulk Vessel Operations amounted to $0 and $2,792 for the three month period ended June 30, 2018 and 2017, respectively and $0 and $7,133 for the six month periods ended June 30, 2018 and 2017, respectively. Profit-sharing revenues are calculated at an agreed percentage of the excess of the charterer’s average daily income (calculated on a quarterly or half-yearly basis) or the Baltic Dry Index over an agreed amount and accounted for on an accrual basis based on provisional amounts and for those contracts that provisional accruals cannot be made due to the nature of the profit sharing elements, these are accounted for on the actual cash settlement. Profit sharing results from the Dry Bulk Vessel Operations for the three month period ended June 30, 2018 and 2017 amounted to $(339) and $300, respectively and for the six month periods ended June 30, 2018 and 2017 amounted to $(205) and $445, respectively. 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. Revenue from port terminal operations of the Logistics business amounted to $20,201 and $11,895 for the three month period ended June 30, 2018 and 2017, respectively and $34,591 and $17,609 for the six month periods ended June 30, 2018 and 2017, respectively. Revenues from storage fees (dry port) of the Logistics business amounted to $74 and $329 for the three month period ended June 30, 2018 and 2017, respectively and $341 and $699 for the six month periods ended June 30, 2018 and 2017, respectively. Dockage revenues from the Logistics business in the dry port terminal operations amounted to $923 and $1,198 for the three month period ended June 30, 2018 and 2017, respectively and $1,530 and $1,854 for the six month periods ended June 30, 2018 and 2017, respectively. 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. Revenues from sale of products by the Logistics business amounted to $9,265 and $8,810 for the three month period ended June 30, 2018 and 2017, respectively and $17,690 and $16,822 for the six month periods ended June 30, 2018 and 2017, respectively. Revenues from liquid port terminal operations from the Logistics business amounted to $860 and $548 for the three month periods ended June 30, 2018 and 2017, respectively and $1,858 and $1,283 for the six month periods ended June 30, 2018 and 2017, respectively. 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. 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. 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. The Company has not entered into FFA trades for any of the periods presented. 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.
Recent Accounting Pronouncements	(d) Recent Accounting Pronouncements: 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 January 2017, FASB issued ASU 2017-03, “Accounting Changes and Error Corrections (Topic 250) and Investments-Equity Method and Joint Ventures (Topic 323)”. The ASU amends the Codification for SEC staff announcements made at recent Emerging Issues Task Force (EITF) meetings. The SEC guidance that specifically relates to our consolidated financial statements was from the September 2016 meeting, where the SEC staff expressed their expectations about the extent of disclosures registrants should make about the effects of the new FASB guidance as well as any amendments issued prior to adoption, on revenue (ASU 2014-09), leases (ASU 2016-02) and credit losses on financial instruments (ASU 2016-13) in accordance with SAB Topic 11.M. Registrants are required to disclose the effect that recently issued accounting standards will have on their financial statements when adopted in a future period. In cases where a registrant cannot reasonably estimate the impact of the adoption, then additional qualitative disclosures should be considered. The ASU incorporates these SEC staff views into ASC 250 and adds references to that guidance in the transition paragraphs of each of the three new standards. The adoption of this ASU did not have a material effect on the Company’s 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. The Company is currently assessing the impact that adopting this new accounting guidance will have on its consolidated financial statements. In February 2016, FASB issued ASU 2016-02, “Leases (Topic 842)”. ASU 2016-02 will apply to both capital (or finance) leases and operating leases. According to ASU 2016-02, lessees will be required to recognize assets (right of use asset) and liabilities (lease liabilities) on the balance sheet for both types of leases, capital (or finance) leases and operating leases, with terms greater than 12 months. ASU 2016 – 02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted. This guidance requires companies to identify lease and non-lease components of a lease agreement. Lease components relate to the right to use the leased asset and non-lease components relate to payments for goods or services that are transferred separately from the right to use the underlying asset. Total lease consideration is allocated to lease and non-lease components on a relative standalone basis. The recognition of revenues related to lease components will be governed by ASC 842 while revenue related to non-lease components will be subject to ASC 606. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842 Leases (“ASU 2018-10”). The amendments in ASU 2018-10 affect narrow aspects of the guidance issued in the amendments in ASU 2016-02. The amendments in this Update affect the amendments in Update 2016-02, which are not yet effective, but for which early adoption upon issuance is permitted. For entities that early adopted Topic 842, the amendments are effective upon issuance of this Update, and the transition requirements are the same as those in Topic 842. For entities that have not adopted Topic 842, the effective date and transition requirements will be the same as the effective date and transition requirements in Topic 842. In addition, in July 2018, the FASB issued ASU 2018-11, Targeted Improvements to Topic 842 Leases (“ASU 2018-11). The improvements in ASU 2018-11 provide for (a) an optional new transition method for adoption that results in initial recognition of a cumulative effect adjustment to retained earnings in the year of adoption and (b) a practical expedient for lessors, under certain circumstances, to combine the lease and non-lease components of revenues for presentation purposes. ASC 842 provides practical expedients that allow entities to not (i) reassess whether any expired or existing contracts are considered or contain leases; (ii) reassess the lease classification for any expired or existing leases; and (iii) reassess initial direct costs for any existing leases. The Company plans to adopt the standard on January 1, 2019 and expects to elect the use of practical expedients. The Company intends to apply the alternative transition method for adoption as described above. Based on a preliminary assessment, the Company expects the adoption of this guidance to have a material impact on its assets and liabilities due to its charter-in contracts and the recognition of right-of-use assets and lease liabilities on its consolidated balance sheets although adoption is not expected to significantly change the recognition, measurement or presentation of lease expenses within the statements of comprehensive (loss)/income or cash flows. With regards to the Company’s charter-out contracts, the Company is not expecting that the adoption will have a material effect on its consolidated financial statements since the Company is a lessor for these charter-out contracts and the changes are fairly minor. The Company expects to elect the use of practical expedient available to lessors which allows good and services embedded in the charter-out contract that qualify as non-lease components to be combined under a single lease component presentation. The Company is continuing its assessment of other miscellaneous leases, which have lease terms greater than 12 months and the Company is the lessee and may identify additional impacts this guidance will have on the consolidated financial statements and disclosures.
