Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 2: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 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 income/(loss), 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, 2020 filed on Form 20-F with the Securities and Exchange Commission (“SEC”). Going concern The interim condensed consolidated financial statements have been prepared on a going concern basis. As of June 30, 2021, Navios Holdings’ current assets totaled $ 206,295 738,929 532,634 83,259 11.25 462,466 7.375 462,466 7,000 455,466 In June 2021, Navios Holdings entered into a supplemental indenture (the “Eighth Supplemental Indenture”) to amend the terms of the indenture governing its 2022 Senior Secured Notes following its receipt of consents from bondholders representing a majority in aggregate principal amount (the “Consenting Noteholders”) of the 2022 Senior Secured Notes The Eighth Supplemental Indenture eliminates the Company’s obligation to make a springing maturity offer for the 2022 Senior Secured Notes following the pro rata redemption, at par, of $ 100,000 The Redemption, which was funded through (i) the sale of a vessel pledged as collateral in respect of the 2022 Senior Secured Notes and (ii) the borrowing of $ 75,264 (the “$115.0 million NSM Loan”), was completed o 20,000 185,000 Although Navios Holdings is currently attempting to address the upcoming maturities of the 2022 Notes and the 2022 Senior Secured Notes and create additional liquidity to fund working capital requirements through the sale of assets and refinancing plans, there can be no assurance Navios Holdings will be successful in such attempts or that any such attempts will be consummated on terms satisfactory to the Company, or at all. Therefore, there is substantial doubt about the Company’s ability to continue as a going concern for the 12- month period from the date of issuance of these consolidated financial statements. In the meantime, Navios Holdings’ internal forecasts and projections indicate that Navios Holdings will generate sufficient cash to make the required principal and interest payments on its borrowings (excluding the above upcoming maturity payments) and provide for the normal working capital requirements of the business for a period of at least 12 months from the date of issuance of these unaudited interim condensed consolidated financial statements. The unaudited interim condensed consolidated financial statements do not include any adjustments that might result from the outcome of these uncertainties. (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: 63.8 Investments in Affiliate Companies: Affiliate companies included in the financial statements accounted for under the equity method: 9.7 28.0 3.9 47.5 (c) Revenue Recognition: 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. 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. The Company recognizes 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. 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. 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. Expenses related to our revenue-generating contracts are recognized as incurred.

(d) Recent Accounting Pronouncements: Adoption of new accounting pronouncements: In December 2019, FASB issued ASU 2019-12, Income Taxes (Topic 740), which modifies ASC 740 to simplify the accounting for income taxes. It removes certain exceptions to the general principles in Topic 740 and amends existing guidance to improve consistent application. The amendments in ASU 2019-12 are effective for public business entities for fiscal years beginning after December 15, 2020, including interim periods therein. Early adoption of the standard is permitted, including adoption in interim or annual periods for which financial statements have not yet been issued. The adoption of this ASU on January 1, 2021 did not have a material impact on the Company’s interim condensed 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 adoption of this ASU on January 1, 2021 did not have a material impact on the Company’s interim condensed consolidated financial statements.

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 at par. Upon occurrence of certain change of control events, the holders of the 2022 Senior Secured Notes may require the Co-Issuers to repurchase some or all of the 2022 Senior Secured Notes at 101 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 affiliate companies, merging or consolidating or selling all or substantially all of the Co-Issuers’ properties and assets and creation or designation of restricted subsidiaries. The indenture governing the 2022 Senior Secured Notes includes customary events of default. The Co-Issuers were in compliance with the covenants as of June 30, 2021. Under the terms of the 2022 Senior Secured Notes, the Company had an obligation to make a springing maturity offer in September 2021 to repurchase those notes at par unless certain conditions relating to the refinancing of our 2022 Notes are met. On October 1, 2020, the Company entered into (1) the Sixth Supplemental Indenture to amend the terms of the indenture and related pledge agreements governing the 2022 Senior Secured Notes following its receipt of consents from bondholders representing a majority in aggregate principal amount (the “Consenting Noteholders”) of the 2022 Senior Secured Notes and (2) a consent agreement with the Consenting Noteholders (“Consent Agreement”) whereby the Consenting Noteholders agreed, subject to the satisfaction of certain conditions in the Consent Agreement, to provide their consents, as part of a consent solicitation to be made by the Company on or before the earlier of (i) 60 days following the consummation of a Qualified IPO (as defined in the Sixth Supplemental Indenture) of Navios Logistics or (ii) September 5, 2021, to the amendments contained in the form of supplemental indenture (“Form of Supermajority Supplemental Indenture”) which amendments require consent from 66 2/3% of the outstanding 2022 Senior Secured Notes affected. The Sixth Supplemental Indenture, among other things, (i) clarifies that all past dividends paid in respect of equity pledged as collateral for the 2022 Senior Secured Notes and any future dividends paid in respect of equity pledged as collateral (other than equity of Navios Logistics) can be used by the Company for general corporate purposes, absent a Default or Event of Default, (ii) provides that future dividends paid in respect of equity of Navios Logistics pledged as collateral for the 2022 Senior Secured Notes may be used only to redeem or repurchase 2022 Senior Secured Notes (including, absent a Default or an Event of Default, at a discount to par), (iii) eliminates the Company’s obligation to make a springing maturity offer for the 2022 Senior Secured Notes; and (iv) states, for the avoidance of doubt, that the Company may agree to the cancellation of amounts it owes to Navios Logistics under that certain loan agreement dated as of April 25, 2019 (as amended) (the “Grimaud Loan”) in lieu of the receipt of pro rata cash dividends from Navios Logistics. The Sixth Supplemental Indenture became effective upon its execution by the Company and the Trustee, but the amendments and waivers contained therein will become operative only upon the occurrence of a Qualified IPO of Navios Logistics. The Form of Supermajority Supplemental Indenture would further amend the Indenture to permit the Company to use the net proceeds it receives from any sale of Navios Logistics equity in connection with or following a Qualified IPO of Navios Logistics to repurchase 2022 Senior Secured Notes at a discount to par in certain circumstances. There can be no assurance that the Company will receive the additional consents necessary to cause the amendments contemplated by the Form of Supermajority Supplemental Indenture to become effective. On November 17, 2020, the Company entered into the Seventh Supplemental Indenture to further amend the terms of the indenture governing the 2022 Senior Secured Notes, pursuant to which Wilmington Trust, National Association became the successor Trustee and successor Collateral Trustee in respect of the 2022 Senior Secured Notes. On June 29, 2021, the Company entered into the Eighth Supplemental Indenture which eliminated the Company’s obligation to make a springing maturity offer for the 2022 Senior Secured Notes following the Redemption. On July 23, 2021, the Company completed the Redemption. The Redemption was funded through (i) the sale of a vessel pledged as collateral in respect of the 2022 Senior Secured Notes and (ii) the borrowing of $ 75,264 The Eighth Supplemental Indenture also, among other things, (i) clarifies that all past dividends paid in respect of equity pledged as collateral for the 2022 Senior Secured Notes and any future dividends paid in respect of equity pledged as collateral (other than equity of Navios Logistics) can be used by the Company for general corporate purposes, absent a Default or Event of Default; (ii) provides that future dividends paid in respect of equity of Navios Logistics pledged as collateral for the 2022 Senior Secured Notes may be used only to redeem or repurchase 2022 Senior Secured Notes; and (iii) permits the lender under the $115.0 million NSM Loan (as defined herein) to take a second lien on the pledged share collateral (which pledged share collateral secures the 2022 Senior Secured Notes on a first lien basis). On July 23, 2021, the Company completed the Redemption of an aggregate principal amount of $ 100,000 100 On September 3, 2021, the Company issued a notice of redemption with respect to an aggregate principal amount of $ 20,000 100 After the Redemption and the Second Redemption, $ 185,000 2022 Notes On November 29, 2013 650,000 7.375 35,661 28,796 35,500 17,642 81,235 50,683 20,782 9,443 11,204 14,356 12,454 1,873 7,000 6,134 855 455,466 The 2022 Notes are senior obligations of the Co-Issuers and were originally secured by first priority ship mortgages on 23 dry bulk vessels 14,250 17 drybulk vessels 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 Co-Issuers have the option to redeem the 2022 Notes in whole or in part at par. Upon occurrence of certain change of control events, the holders of the 2022 Notes may require the Co-Issuers to repurchase some or all of the 2022 Notes at 101 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 affiliate companies, merging or consolidating or selling all or substantially all of the Co-Issuers’ properties and assets and creation or designation of restricted subsidiaries. The indenture governing the 2022 Notes includes customary events of default. The Co-Issuers were in compliance with the covenants as of June 30, 2021. 2024 Notes On March 21, 2019 4,747 9.75 10,930 On April 21, 2019 3,879 8,841 The 2024 Notes are Navios Holdings’ senior unsecured general obligations and rank senior in right of payment to any of Navios Holding’s existing and future debt that expressly provides that it is subordinated to the 2024 Notes, pari passu in right of payment with all of Navios Holding’s existing and future senior obligations, structurally subordinated in right of payment to the obligations of Navios Holding’s subsidiaries, and effectively subordinated in right of payment to any existing and future obligations of Navios Holdings that are secured by property or assets that do not secure the 2024 Notes, including the 2022 Senior Secured Notes and the 2022 Notes, to the extent of the value of any such property and assets securing such other obligations. The 2024 Notes are not guaranteed by any of Navios Holdings’ subsidiaries. The indenture governing the 2024 Notes does not contain restrictive covenants but does include customary events of default. Navios Holdings has the option to redeem the 2024 Notes, in whole or in part, at any time, at a redemption price equal to 100 NSM Loan On August 29, 2019 141,795 57,026 358 $50.0 million NSM Loan In June 2020, Navios Holdings entered into a secured loan agreement with Navios Shipmanagement Holdings Corporation, a wholly owned subsidiary of NSM (“$50.0 million NSM Loan”) for a loan of up to $ 50,000 39,986 250 $115.0 million NSM Loan In June 2021, Navios Holdings entered into a secured loan agreement with Navios Shipmanagement Holdings Corporation, a wholly owned subsidiary of NSM (“$115.0 million NSM Loan”) for a loan up to $ 115,000 Sale and Leaseback Agreements In the first quarter of 2020, the Company entered into two sale and leaseback agreements of $ 68,000 The Sale and Leaseback Agreements are repayable by 144 monthly 224 238 60,165 fourth quarter of 2031 first quarter of 2032 750 The Sale and Leaseback Agreements have no financial covenants. 2025 Logistics Senior Notes On July 8, 2020 500,000 10.75 On or after August 1, 2022, the Logistics Co-Issuers may redeem some or all of the 2025 Logistics Senior Notes at the redemption prices set forth in the indenture governing the 2025 Logistics Senior Notes. In addition, before August 1, 2022, the Logistics Co-Issuers may redeem up to 35 110.750 100 The 2025 Logistics Senior Notes are senior secured obligations of the Logistics Co-Issuers and rank equal in right of payment to all of their existing and future senior indebtedness and senior in right of payment to all of their future subordinated indebtedness. The 2025 Logistics Senior Notes are fully and unconditionally guaranteed, jointly and severally, by all of the Navios Logistics’ direct and indirect subsidiaries, other than the Logistics Co-Issuer and Grimaud Ventures S.A (the “Grimaud”).

Accounting Policies [Abstract]
(a) 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 income/(loss), 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, 2020 filed on Form 20-F with the Securities and Exchange Commission (“SEC”). Going concern The interim condensed consolidated financial statements have been prepared on a going concern basis. As of June 30, 2021, Navios Holdings’ current assets totaled $ 206,295 738,929 532,634 83,259 11.25 462,466 7.375 462,466 7,000 455,466 In June 2021, Navios Holdings entered into a supplemental indenture (the “Eighth Supplemental Indenture”) to amend the terms of the indenture governing its 2022 Senior Secured Notes following its receipt of consents from bondholders representing a majority in aggregate principal amount (the “Consenting Noteholders”) of the 2022 Senior Secured Notes The Eighth Supplemental Indenture eliminates the Company’s obligation to make a springing maturity offer for the 2022 Senior Secured Notes following the pro rata redemption, at par, of $ 100,000 The Redemption, which was funded through (i) the sale of a vessel pledged as collateral in respect of the 2022 Senior Secured Notes and (ii) the borrowing of $ 75,264 (the “$115.0 million NSM Loan”), was completed o 20,000 185,000 Although Navios Holdings is currently attempting to address the upcoming maturities of the 2022 Notes and the 2022 Senior Secured Notes and create additional liquidity to fund working capital requirements through the sale of assets and refinancing plans, there can be no assurance Navios Holdings will be successful in such attempts or that any such attempts will be consummated on terms satisfactory to the Company, or at all. Therefore, there is substantial doubt about the Company’s ability to continue as a going concern for the 12- month period from the date of issuance of these consolidated financial statements. In the meantime, Navios Holdings’ internal forecasts and projections indicate that Navios Holdings will generate sufficient cash to make the required principal and interest payments on its borrowings (excluding the above upcoming maturity payments) and provide for the normal working capital requirements of the business for a period of at least 12 months from the date of issuance of these unaudited interim condensed consolidated financial statements. The unaudited interim condensed consolidated financial statements do not include any adjustments that might result from the outcome of these uncertainties.
(b) 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: 63.8 Investments in Affiliate Companies: Affiliate companies included in the financial statements accounted for under the equity method: 9.7 28.0 3.9 47.5
(c) Revenue Recognition:	(c) Revenue Recognition: 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. 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. The Company recognizes 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. 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. 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. Expenses related to our revenue-generating contracts are recognized as incurred.

(d) Recent Accounting Pronouncements:	(d) Recent Accounting Pronouncements: Adoption of new accounting pronouncements: In December 2019, FASB issued ASU 2019-12, Income Taxes (Topic 740), which modifies ASC 740 to simplify the accounting for income taxes. It removes certain exceptions to the general principles in Topic 740 and amends existing guidance to improve consistent application. The amendments in ASU 2019-12 are effective for public business entities for fiscal years beginning after December 15, 2020, including interim periods therein. Early adoption of the standard is permitted, including adoption in interim or annual periods for which financial statements have not yet been issued. The adoption of this ASU on January 1, 2021 did not have a material impact on the Company’s interim condensed 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 adoption of this ASU on January 1, 2021 did not have a material impact on the Company’s interim condensed consolidated financial statements.
