Organization Consolidation And Presentation Of Financial Statements [Abstract]
DESCRIPTION OF BUSINESS	NOTE 1: DESCRIPTION OF BUSINESS Navios Maritime Midstream Partners L.P. (“Navios Midstream” or the “Company”) (NYSE: NAP), was formed in The Republic of the Marshall Islands on October 13, 2014. Navios Maritime Midstream Partners GP LLC (the “General Partner”), a Marshall Islands limited liability company and wholly-owned subsidiary of Navios Maritime Acquisition Corporation (“Navios Acquisition”), was also formed on that date to act as the General Partner of Navios Midstream and receive a 2.0% general partner interest. Navios Midstream’s principal activity is to own, operate and acquire crude oil tankers under long-term employment contracts as well as refined petroleum product tankers, chemical tankers, and LPG tankers under long-term employment contracts. The Company intends to charter the vessels under long-term employment contracts to international oil companies, refiners, and large vessel operators. On June 18, 2018, in accordance with the terms of the Partnership Agreement all of the issued and outstanding 1,592,920 subordinated Series A units converted into Navios Midstream’s existing common units on a one-for-one basis. Following the conversion of subordinated Series A units into common units the capital allocated to the holders of the subordinated series A units was reclassified to the capital of the holders of the common units. As of June 30, 2018, there were outstanding: 20,947,418 common units, no subordinated units, no subordinated Series A units and 427,499 general partnership units. As of June 30, 2018, Navios Acquisition owned a 59.0% limited partner interest in Navios Midstream, which included a 2.0% general partner interest.

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 Midstream’s condensed consolidated financial position, statements of operations and cash flows for the periods presented. Adjustments consist of normal, recurring entries. The yearend condensed balance sheet data was derived from audited financial statements, but does not include all disclosure required by accounting principles generally accepted in the United States of America (“GAAP”). 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 GAAP for complete financial statements. These interim financial statements should be read in conjunction with the Company’s consolidated financial statements and notes included in Navios Midstream’s 2017 Annual Report filed on Form 20-F with the U.S. Securities and Exchange Commission. (b) Principles of consolidation: The accompanying interim condensed consolidated financial statements include the accounts of Navios Midstream, a Marshall Islands corporation, and its subsidiaries that are all 100% owned. All significant intercompany balances and transactions have been eliminated in the condensed consolidated statements. (c) Restricted Cash: Restricted cash was $0 and $10,000 as of June 30, 2018 and December 31, 2017, respectively, and was held as required by certain provisions of Navios Midstream’s credit facility. The following table provides a reconciliation of cash, cash equivalents and restricted cash to amounts reported within the condensed consolidated balance sheet: Reconciliation of cash, cash equivalents and restricted cash: June 3 0 , 2018 December 31, 2017 Current assets: Cash and cash equivalents $ 21, 731 $ 27,086 Restricted cash — 10,000 Total cash, cash equivalents and restricted cash $ 21, 731 $ 37,086 (d) Revenue recognition: On January 1, 2018, the Company adopted the provisions of ASC 606, Revenue from Contracts with Customers (ASC 606). The guidance provides a unified model to determine how revenue is recognized. In doing so, the Company makes judgments including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price, and allocating the transaction price to each performance obligation. Revenue is recognized when (or as) the Company transfers promised goods or services to its customers in amounts that reflect the consideration to which the company expects to be entitled to in exchange for those goods or services, which occurs when (or as) the Company satisfies its contractual obligations and transfers control of the promised goods or services to its customers. Revenues are recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In determining the appropriate amount of revenue to be recognized as it fulfills its obligations under its agreements, the Company performs the following steps: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations, including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations based on estimated selling prices; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation. The Company’s contract revenues consist of revenues from time chartering and pooling arrangements. Upon adoption of ASC 606, the timing and recognition of earnings from the pool arrangements and time charter contracts to which the Company is party did not change significantly from previous practice. Revenues from time chartering of vessels are accounted for as operating leases and are therefore recognized on a straight-line basis as the average revenue over the rental periods of such charter agreements, as service is performed. A time charter involves placing a vessel at the charterers’ disposal for a period of time during which the charterer uses the vessel in return for the payment of a specified daily hire rate. Under time charters, operating costs such as for crews, maintenance and insurance are typically paid by the owner of the vessel. Revenues from time chartering of vessels amounted to $11,606 and $11,033 for the three month periods ended June 30, 2018 and 2017, respectively. Revenues from time chartering of vessels amounted to $23,085 and $27,411 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. Accordingly, the Company accounts for its agreements with commercial pools as variable rate operating leases. For the pools in which the Company participates, management monitors, among other things, the relative proportion of the Company’s vessels operating in each of the pools to the total number of vessels in each of the respective pools, and assesses whether or not the Company’s participation interest in each of the pools is sufficiently significant so as to determine that the Company has effective control of the pool. Profit-sharing revenues are calculated at an agreed percentage of the excess of the charterer’s average daily income (calculated on a quarterly, half-yearly or annually basis) over an agreed amount and accounted for on an accrual basis based on provisional amounts and for those contracts that provisional accruals cannot be made due to the nature of the profit share elements, these are accounted for or when such revenue becomes determinable. Revenue from vessels operating in pooling and profit sharing arrangements amounted $3,470 and $3,401 for the three month periods ended June 30, 2018 and 2017, respectively. Revenue from vessels operating in pooling and profit sharing arrangements amounted $6,903 and $6,968 for the six month periods ended June 30, 2018 and 2017, respectively. Revenue from backstop agreements: For more information on revenue from backstop agreements, please refer to Note 8. Revenue from backstop agreements amounted to $5,714 and $4,075 for the three month periods ended June 30, 2018 and 2017, respectively. Revenue from backstop agreements amounted to $10,581 and $5,231 for the six month periods ended June 30, 2018 and 2017, respectively. 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. 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. For the six month period ended June 30, 2018, customers representing 10% or more of our total revenue were Dalian Ocean Shipping Co. Ltd. (“Cosco Dalian”), a Chinese state-owned enterprise, VL8 Pool Inc. (“VL8”) and SK Shipping Company Limited (“SK Shipping”) that accounted for 43.5%, 17.0% and 13.4%, respectively, of our revenue. For the year ended December 31, 2017, our customers representing 10% or more of our total revenue were Cosco Dalian and VL8 that accounted for 44.7% and 15.1%, respectively, of our revenue. Adoption of new accounting standards On January 1, 2018, the Company adopted ASU No. 2014-09, “Revenue from Contracts with Customers” and the related amendments (“ASC 606” or “the new revenue standard”) using the modified retrospective method, requiring to recognize the cumulative effect of adopting this guidance as an adjustment to the 2018 opening balance of retained earnings and not retrospectively adjusting prior periods. Under the new guidance, there is a five-step model to apply to revenue recognition. The five-steps consist of: (1) determination of whether a contract, an agreement between two or more parties that creates legally enforceable rights and obligations, exists; (2) identification of the performance obligations in the contract; (3) determination of the transaction price; (4) allocation of the transaction price to the performance obligations in the contract; and (5) recognition of revenue when (or as) the performance obligation is satisfied. As a result of adoption, there was no cumulative impact to the Company’s retained earnings at January 1, 2018. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. The Company expects the impact of the adoption of the new standard to be immaterial to its net income on an ongoing basis. In August 2016, the FASB issued Accounting Standards Update No. 2016-15, “Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments” (“ASU 2016-15”). This Update addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The Company adopted the new guidance on January 1, 2018 and it did not have a material impact on the consolidated results of operations, financial condition, or cash flows. In January 2017, FASB issued ASU 2017-01, “Business Combinations” to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisition (or disposals) of assets or businesses. Under current implementation guidance the existence of an integrated set of acquired activities (inputs and processes that generate outputs) constitutes an acquisition of business. This ASU provides a screen to determine when a set of assets and activities does not constitute a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This update is effective for public entities with reporting periods beginning after December 15, 2017, including interim periods within those years. The amendments of this ASU should be applied prospectively on or after the effective date. The Company adopted the requirements of ASU 2017-01 effective beginning on January 1, 2018. The adoption of this ASU did not have a material effect on the Company’s consolidated financial statements, results of operations and cash flows. On January 1, 2018 the Company adopted ASU 2016-18, “Restricted Cash” (“ASU 2016-18”), which updated ASC Topic 230, “Statement of Cash Flows.” ASU 2016-18 required companies to include restricted cash and restricted cash equivalents with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The adoption of this standard resulted in a decrease in net cash used in financing activities of $10,000 for the six months ended June 30, 2017 (no restricted cash as of June 30, 2018). Recent Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). ASU 2016-02 will apply to both types of leases – capital (or finance) leases and operating leases. According to the new Accounting Standard, (a) lessees will be required to recognize assets and liabilities on the balance sheet for the rights and obligations created by all leases with terms of more than 12 months and (b) previous accounting standards for lessors will be updated to align certain requirements with the updates to lessee accounting standards and the revenue recognition accounting standards. ASU 2016 – 02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted. 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. The Company intends to apply the alternative transition method, which is consistent, in application, with the approach the Company has elected under the revenue accounting standards update, and intends to elect the practical expedient for lessors with regards to the contracts for its vessels, for presentation purposes. The Company’s adoption, and the ultimate effect on the consolidated financial statements, will be based on an evaluation of the contract-specific facts and circumstances. The Company does not expect any changes to the timing of revenue recognition for the current contracts with customers. The Company is currently assessing the impact that adopting this new accounting guidance will have on its consolidated financial statements and footnotes disclosures.

Fair Value Disclosures [Abstract]
FAIR VALUE OF FINANCIAL INSTRUMENTS	NOTE 7: FAIR VALUE OF FINANCIAL INSTRUMENTS 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 approximate their fair value because of the short maturity of these investments. Accounts receivable, net: Carrying amounts are considered to approximate fair value due to the short-term nature of these accounts receivables and no significant changes in interest rates. All amounts that are assumed to be uncollectible are written-off and/or reserved. Accounts payable: The carrying amount of accounts payable reported in the balance sheet approximates its fair value due to the short-term nature of these accounts payable and no significant changes in interest rates. Due from related parties, current: The carrying amount of due from related parties, current reported in the balance sheet approximates its fair value due to the short-term nature of these receivables. Due from related parties, non-current: The carrying amount of due from related parties, non-current reported in the balance sheet approximates its fair value. Term Loan B facility: The fair value of the Company’s debt is estimated based on currently available debt with similar contract terms, interest rate and remaining maturities, as well as taking into account our creditworthiness. The fair value hierarchy is explained as follows: Level I: Inputs are unadjusted, quoted prices for identical assets or liabilities in active markets that we have the ability to access. Valuation of these items does not entail a significant amount of judgment. Level II: Inputs other than quoted prices included in Level I that are observable for the asset or liability through corroboration with market data at the measurement date. Level III: Inputs that are unobservable. The Company did not use any Level 3 inputs as of June 30 , 2018 or December 31, 2017.

Segment Reporting [Abstract]
SEGMENT INFORMATION	NOTE 10: SEGMENT INFORMATION The Company reports financial information and evaluates its operations by charter revenues. The Company does not use discrete financial information to evaluate operating results for each type of charter. As a result, management reviews operating results solely by revenue per day and operating results of the fleet and thus the Company has determined that it operates under one reportable segment. Company monitors operating revenue by geographic region for the Company’s reportable segment. Revenue is allocated on the basis of the geographic region in which the customer is located. Revenues from specific geographic regions which contribute over 10% of total revenue are disclosed separately. For the three and six month periods ended June 30, 2018 and 2017 , all the revenues were derived from customers located in Asia. Vessels operate on a worldwide basis and are not restricted to specific locations. Accordingly, it is not possible to allocate the assets of these operations to specific countries.

Cash Distributions And Earnings Per Unit [Abstract]
CASH DISTRIBUTIONS AND EARNINGS/ (LOSSES) PER UNIT	NOTE 12: CASH DISTRIBUTIONS AND EARNINGS/ (LOSSES) PER UNIT The partnership agreement of Navios Midstream requires that all available cash is distributed quarterly, after deducting expenses, including estimated maintenance and replacement capital expenditures and reserves. Distributions may be restricted by, among other things, the provisions of existing and future indebtedness, applicable partnership and limited liability company laws and other laws and regulations. Incentive distribution rights represent the right to receive an increasing percentage of quarterly distributions of available cash from operating surplus after the minimum quarterly distribution and the target distribution levels have been achieved. Our general partner currently holds the incentive distribution rights, but may transfer these rights separately from its general partner interest, subject to restrictions in the partnership agreement. Thereafter there are incentive distribution rights held by the General Partner, which are analyzed as follows: Marginal Percentage Interest in Distributions Total Quarterly Distribution Total Amount Common and subordinated Unitholders General Partner Holders of IDRs Minimum Quarterly Distribution $ 0.4125 98.0 % 2.0 % 0 % First Target Distribution up to $ 0.4744 98.0 % 2.0 % 0 % Second Target Distribution above $ 0.4744 85.0 % 2.0 % 13.0 % up to $ 0.5156 Third Target Distribution above $ 0.5156 75.0 % 2.0 % 23.0 % up to $ 0.6188 Thereafter above $ 0.6188 50.0 % 2.0 % 48.0 % In November 2017, the then outstanding subordinated units converted into common units in accordance with the Navios Midstream’s Limited Partnership Agreement. On June 18, 2018, in accordance with the terms of the Partnership Agreement all of the issued and outstanding 1,592,920 subordinated Series A units converted into Navios Midstream’s existing common units on a one-for-one basis. On January 22, 2018, the Board of Directors authorized its quarterly cash distribution for the three month period ended December 31, 2017 of $0.4225 per unit. The distribution was paid on February 14, 2018 to all holders of record of common, subordinated Series A units and general partner units on February 9, 2018. The aggregate amount of the distribution paid was $9,031. On March 26, 2018, the Board of Directors has set the annual distribution policy to $0.50 per unit. On April 26, 2018, the Board of Directors authorized its quarterly cash distribution for the three month period ended March 31, 2018 of $0.125 per unit. The distribution was paid on May 11, 2018 to all holders of record holders of common units, subordinated Series A units and general partner units on May 9, 2018. The aggregate amount of the distribution paid was $2,671. Navios Midstream calculates earnings per unit by allocating reported net income for each period to each class of units based on the distribution waterfall for available cash specified in Navios Midstream’s partnership agreement, net of the unallocated earnings. Basic earnings per unit are determined by dividing net income by the weighted average number of units outstanding during the period. Basic and diluted net earnings per unit are the same because the Company does not have any potentially dilutive units outstanding for the period presented. Net loss per unit undistributed is determined by taking the distributions in excess of net income and allocating between common units, subordinated units and general partner units on a 98%-2% basis. The calculations of the basic and diluted earnings per unit are presented below.

Income Tax Disclosure [Abstract]
INCOME TAXES	NOTE 13: INCOME TAXES Marshall Islands, British Virgin Islands, and Hong Kong, do not impose a tax on international shipping income. Under the laws of Marshall Islands, British Virgin Islands, and Hong Kong, of the companies’ incorporation and vessels’ registration, the companies are subject to registration and tonnage taxes which have been included in the daily management fee. In accordance with the currently applicable Greek law, foreign flagged vessels that are managed by Greek or foreign ship management companies having established an office in Greece are subject to duties towards the Greek state, which are calculated on the basis of the relevant vessels’ tonnage. The payment of said duties exhausts the tax liability of the foreign ship owning company and the relevant manager against any tax, duty, charge or contribution payable on income from the exploitation of the foreign flagged vessel. Pursuant to Section 883 of the Internal Revenue Code of the United States, U.S. source income from the international operation of ships is generally exempt from U.S. income tax if the company operating the ships meets certain incorporation and ownership requirements. Among other things, in order to qualify for this exemption, the company operating the ships must be incorporated in a country, which grants an equivalent exemption from income taxes to U.S. corporations. All of the Company’s vessel- owning subsidiaries satisfy these initial criteria. In addition, these companies must meet an ownership test. Subject to proposed regulations becoming finalized in their current form, the management of Navios Midstream believes by virtue of a special rule applicable to situations where the ship operating companies are beneficially owned by a publicly traded company like Navios Midstream, the second criterion can also be satisfied based on the trading volume and ownership of the Company’s units, but no assurance can be given that this will remain so in the future.

Revenue recognition	(d) Revenue recognition: On January 1, 2018, the Company adopted the provisions of ASC 606, Revenue from Contracts with Customers (ASC 606). The guidance provides a unified model to determine how revenue is recognized. In doing so, the Company makes judgments including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price, and allocating the transaction price to each performance obligation. Revenue is recognized when (or as) the Company transfers promised goods or services to its customers in amounts that reflect the consideration to which the company expects to be entitled to in exchange for those goods or services, which occurs when (or as) the Company satisfies its contractual obligations and transfers control of the promised goods or services to its customers. Revenues are recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In determining the appropriate amount of revenue to be recognized as it fulfills its obligations under its agreements, the Company performs the following steps: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations, including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations based on estimated selling prices; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation. The Company’s contract revenues consist of revenues from time chartering and pooling arrangements. Upon adoption of ASC 606, the timing and recognition of earnings from the pool arrangements and time charter contracts to which the Company is party did not change significantly from previous practice. Revenues from time chartering of vessels are accounted for as operating leases and are therefore recognized on a straight-line basis as the average revenue over the rental periods of such charter agreements, as service is performed. A time charter involves placing a vessel at the charterers’ disposal for a period of time during which the charterer uses the vessel in return for the payment of a specified daily hire rate. Under time charters, operating costs such as for crews, maintenance and insurance are typically paid by the owner of the vessel. Revenues from time chartering of vessels amounted to $11,606 and $11,033 for the three month periods ended June 30, 2018 and 2017, respectively. Revenues from time chartering of vessels amounted to $23,085 and $27,411 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. Accordingly, the Company accounts for its agreements with commercial pools as variable rate operating leases. For the pools in which the Company participates, management monitors, among other things, the relative proportion of the Company’s vessels operating in each of the pools to the total number of vessels in each of the respective pools, and assesses whether or not the Company’s participation interest in each of the pools is sufficiently significant so as to determine that the Company has effective control of the pool. Profit-sharing revenues are calculated at an agreed percentage of the excess of the charterer’s average daily income (calculated on a quarterly, half-yearly or annually basis) over an agreed amount and accounted for on an accrual basis based on provisional amounts and for those contracts that provisional accruals cannot be made due to the nature of the profit share elements, these are accounted for or when such revenue becomes determinable. Revenue from vessels operating in pooling and profit sharing arrangements amounted $3,470 and $3,401 for the three month periods ended June 30, 2018 and 2017, respectively. Revenue from vessels operating in pooling and profit sharing arrangements amounted $6,903 and $6,968 for the six month periods ended June 30, 2018 and 2017, respectively. Revenue from backstop agreements: For more information on revenue from backstop agreements, please refer to Note 8. Revenue from backstop agreements amounted to $5,714 and $4,075 for the three month periods ended June 30, 2018 and 2017, respectively. Revenue from backstop agreements amounted to $10,581 and $5,231 for the six month periods ended June 30, 2018 and 2017, respectively. 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. 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. For the six month period ended June 30, 2018, customers representing 10% or more of our total revenue were Dalian Ocean Shipping Co. Ltd. (“Cosco Dalian”), a Chinese state-owned enterprise, VL8 Pool Inc. (“VL8”) and SK Shipping Company Limited (“SK Shipping”) that accounted for 43.5%, 17.0% and 13.4%, respectively, of our revenue. For the year ended December 31, 2017, our customers representing 10% or more of our total revenue were Cosco Dalian and VL8 that accounted for 44.7% and 15.1%, respectively, of our revenue.
Adoption of new accounting standars	Adoption of new accounting standards On January 1, 2018, the Company adopted ASU No. 2014-09, “Revenue from Contracts with Customers” and the related amendments (“ASC 606” or “the new revenue standard”) using the modified retrospective method, requiring to recognize the cumulative effect of adopting this guidance as an adjustment to the 2018 opening balance of retained earnings and not retrospectively adjusting prior periods. Under the new guidance, there is a five-step model to apply to revenue recognition. The five-steps consist of: (1) determination of whether a contract, an agreement between two or more parties that creates legally enforceable rights and obligations, exists; (2) identification of the performance obligations in the contract; (3) determination of the transaction price; (4) allocation of the transaction price to the performance obligations in the contract; and (5) recognition of revenue when (or as) the performance obligation is satisfied. As a result of adoption, there was no cumulative impact to the Company’s retained earnings at January 1, 2018. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. The Company expects the impact of the adoption of the new standard to be immaterial to its net income on an ongoing basis. In August 2016, the FASB issued Accounting Standards Update No. 2016-15, “Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments” (“ASU 2016-15”). This Update addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The Company adopted the new guidance on January 1, 2018 and it did not have a material impact on the consolidated results of operations, financial condition, or cash flows. In January 2017, FASB issued ASU 2017-01, “Business Combinations” to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisition (or disposals) of assets or businesses. Under current implementation guidance the existence of an integrated set of acquired activities (inputs and processes that generate outputs) constitutes an acquisition of business. This ASU provides a screen to determine when a set of assets and activities does not constitute a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This update is effective for public entities with reporting periods beginning after December 15, 2017, including interim periods within those years. The amendments of this ASU should be applied prospectively on or after the effective date. The Company adopted the requirements of ASU 2017-01 effective beginning on January 1, 2018. The adoption of this ASU did not have a material effect on the Company’s consolidated financial statements, results of operations and cash flows. On January 1, 2018 the Company adopted ASU 2016-18, “Restricted Cash” (“ASU 2016-18”), which updated ASC Topic 230, “Statement of Cash Flows.” ASU 2016-18 required companies to include restricted cash and restricted cash equivalents with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The adoption of this standard resulted in a decrease in net cash used in financing activities of $10,000 for the six months ended June 30, 2017 (no restricted cash as of June 30, 2018). Recent Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). ASU 2016-02 will apply to both types of leases – capital (or finance) leases and operating leases. According to the new Accounting Standard, (a) lessees will be required to recognize assets and liabilities on the balance sheet for the rights and obligations created by all leases with terms of more than 12 months and (b) previous accounting standards for lessors will be updated to align certain requirements with the updates to lessee accounting standards and the revenue recognition accounting standards. ASU 2016 – 02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted. 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. The Company intends to apply the alternative transition method, which is consistent, in application, with the approach the Company has elected under the revenue accounting standards update, and intends to elect the practical expedient for lessors with regards to the contracts for its vessels, for presentation purposes. The Company’s adoption, and the ultimate effect on the consolidated financial statements, will be based on an evaluation of the contract-specific facts and circumstances. The Company does not expect any changes to the timing of revenue recognition for the current contracts with customers. The Company is currently assessing the impact that adopting this new accounting guidance will have on its consolidated financial statements and footnotes disclosures.

Intercompany Agreements Description			On November 18, 2014, Navios Acquisition entered into backstop agreements with Navios Midstream. In accordance with the terms of the backstop agreements, Navios Acquisition has provided a backstop commitment at a net rate of $35.0 per day for the Nave Celeste, $38.4 per day for the Shinyo Ocean and $38.0 per day for the Shinyo Kannika. The backstop rates apply for a two-year period as of the redelivery of each of the vessels from its original charterer, if the actual rates achieved are below the agreed backstop rates for each of the vessels.

Navios Acquisition agreed to extend the backstop commitment of the Shinyo Kannika to the Nave Galactic, following the acquisition of the latter by Navios Acquisition in March 2018. For the three and six month periods ended June 30, 2018, backstop revenue amounted to $5,714 and $10,581, respectively and was included in the balance due from related parties (see paragraph above in current note).
