Operating and Financial Review and Prospects

The following is a discussion of the financial condition and results of operations for the three and six month periods ended June 30, 2018 and 2017 of Navios Maritime Midstream Partners L.P. (referred to herein as “we”, “us”, “Navios Midstream” or the “Company”). All of the financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”). You should read this section together with the consolidated financial statements and the accompanying notes included in Navios Midstream’s 2017 Annual Report (the “2017 Annual Report”) filed on Form 20-F with the U.S. Securities and Exchange Commission.

This report contains forward-looking statements (as defined in Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended) concerning future events and expectations, including with respect to Navios Midstream’s future dividends and Navios Midstream’s growth strategy and measures to implement such strategy; including expected vessel acquisitions and entering into further employment contracts. Words such as “may,” “expects,” “intends,” “plans,” “believes,” “anticipates,” “hopes,” “estimates,” and variations of such words and similar expressions are intended to identify forward-looking statements. Such statements include comments regarding expected revenue and employment contracts, and any potential merger with Navios Acquisition. These forward-looking statements are based on the information available to, and the expectations and assumptions deemed reasonable by, Navios Midstream at the time these statements were made. Although Navios Midstream believes that the expectations reflected in such forward-looking statements are reasonable, no assurance can be given that such expectations will prove to have been correct. These statements involve known and unknown risks and are based upon a number of assumptions and estimates that are inherently subject to significant uncertainties and contingencies, many of which are beyond the control of Navios Midstream. Actual results may differ materially from those expressed or implied by such forward-looking statements. Factors that could cause actual results to differ materially include, but are not limited to, the timing and ability to consummate the potential merger with Navios Acquisition, the creditworthiness of our charterers and the ability of our contract counterparties to fulfill their obligations to us, tanker industry trends, including charter rates and vessel values and factors affecting vessel supply and demand, the aging of our vessels and resultant increases in operation and drydocking costs, the loss of any customer or charter or vessel, our ability to repay outstanding indebtedness, to obtain additional financing and to obtain replacement charters for our vessels, in each case, at commercially acceptable rates or at all, increases in costs and expenses, including but not limited to: crew wages, insurance, provisions, port expenses, lube oil, bunkers, repairs, maintenance and general and administrative expenses, the expected cost of, and our ability to comply with, governmental regulations and maritime self-regulatory organization standards, as well as standard regulations imposed by our charterers applicable to our business, potential liability from litigation and our vessel operations, including discharge of pollutants, general domestic and international political conditions, competitive factors in the market in which Navios Midstream operates; risks associated with operations outside the United States; and other factors listed from time to time in Navios Midstream’s filings with the U.S. Securities and Exchange Commission including its Form 20-Fs and Form 6-Ks. Navios Midstream expressly disclaims any obligations or undertaking to release publicly any updates or revisions to any forward-looking statements contained herein to reflect any change in Navios Midstream’s expectations with respect thereto or any change in events, conditions or circumstances on which any statement is based. Navios Midstream makes no prediction or statement about the performance of its common units.

Overview

Navios Midstream was formed on October 13, 2014, as a Marshall Islands limited partnership to own, operate and acquire crude oil tankers, refined petroleum product tankers, chemical tankers, and LPG tankers under long-term employment contracts. Navios Maritime Midstream Partners GP LLC, a wholly-owned subsidiary of Navios Maritime Acquisition Corporation (“Navios Acquisition”), was formed on October 13, 2014 to act as our general partner. On November 18, 2014, we completed our initial public offering (“IPO”).

Recent Developments

Merger Proposal from Navios Acquisition  

On July 2, 2018, Navios Midstream announced that its board of directors had received a proposal from Navios Maritime Acquisition Corporation (“Navios Acquisition”) (NYSE: NNA) pursuant to which Navios Acquisition would acquire the publicly held common units of Navios Midstream not already owned by Navios Acquisition in a stock for units exchange.

3

Subject to negotiation and execution of a definitive agreement, Navios Acquisition proposed consideration of 6.292 Navios Acquisition shares for each outstanding publicly held common unit of Navios Midstream as part of a transaction that would be structured as a merger of Navios Midstream with and into Navios Acquisition.

The proposed transaction is subject to the negotiation and execution of a definitive agreement, approval of the board of directors of Navios Acquisition and the necessary approvals of the conflicts committee of Navios Midstream under our partnership agreement. The consummation of the proposed transaction would be subject to customary closing conditions. There can be no assurance that any such approvals will be forthcoming, that a definitive agreement will be executed, or that any transaction will be consummated.

Equity Transactions

On July 29, 2016, Navios Midstream entered into a Continuous Offering Program Sales Agreement (the “Sales Agreement”) with S. Goldman Capital LLC, as sales agent (the “Agent”), pursuant to which Navios Midstream may issue and sell from time to time through the Agent common units representing limited partner interests having an aggregate offering price of up to $25.0 million.

There were no equity transactions or units sold under this program in the three and the six month periods ended June 30, 2018.

On June 18, 2018, in accordance with the terms of our 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 subordinated series A units was reclassified to the capital of the holders of common unit.

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.

Our Fleet

Our fleet consists of six very large crude carriers (“VLCC”), which have an average remaining employment term of approximately 2.8 years, including the backstop commitment from Navios Acquisition. They are chartered to three counterparties, Dalian Ocean Shipping Co. Ltd. (“Cosco Dalian”), a Chinese state-owned enterprise, SK Shipping Company Limited (“SK Shipping”) and VL8 Pool Inc. (“VL8”).

The following table provides summary information about our fleet as of July 31, 2018:

Option Vessels

We have options, exercisable through November 18, 2018, to purchase the following three VLCCs from Navios Acquisition at fair market value. Although we anticipate that we may exercise some or all of our options to purchase the following three VLCCs, the timing of such purchases is uncertain and each such purchase is subject to various conditions, including reaching an agreement with Navios Acquisition regarding the fair market value of the vessel and the availability of financing, which we anticipate would be from external sources. Generally, we expect to fund the acquisition of any or all of the three additional VLCCs we may elect to purchase with cash from operations, bank borrowings and the issuance of debt and equity securities.

The following table provides summary information about the vessels subject to the options as of July 31, 2018:

Our Customers

We provide seaborne shipping services under contracts with customers that we believe are creditworthy.

For the six month period ended June 30, 2018, customers representing 10% or more of our total revenue were Cosco Dalian, VL8 and 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.

Our revenues are driven by the number of vessels in the fleet, the number of days during which the vessels operate and our charters hire rates, which, in turn, are affected by a number of factors, including:

5

Time charters are available for varying periods, ranging from a single trip (spot charter) to long-term which may be many years. In general, a long-term time charter assures the vessel owner of a consistent stream of revenue. Operating the vessel in the spot market affords the owner greater spot market opportunity, which may result in high rates when vessels are in high demand or low rates when vessel availability exceeds demand. We intend to operate our vessels in the long-term charter market. Vessel charter rates are affected by world economics, international events, weather conditions, strikes, governmental policies, supply and demand and many other factors that might be beyond our control. Please read “Risk Factors” in our 2017 Annual Report, filed with SEC on March 9, 2018, for a discussion of certain risks inherent in our business.

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 when an agreement with the pool exists, price is fixed, service is provided and the collectability is reasonably assured.

If we lose a charter, we may be unable to re-deploy the related vessel on terms as favorable to us due to the long-term nature of certain charters and the cyclical nature of the industry or we may be forced to charter the vessel on the spot market at then market rates which may be less favorable than the charter that has been terminated. The loss of any of our customers, time charters or vessels, or a decline in payments under our charters, could have a material adverse effect on our business, results of operations and financial condition and our ability to make cash distributions in the event we are unable to replace such customer, time charter or vessel.

Under some of our time charters, either party may terminate the charter contract in the event of war in specified countries or in locations that would significantly disrupt the free trade of the vessel. Some of the time charters covering our vessels require us to return to the charterer, upon the loss of the vessel, all advances paid by the charterer but not earned by us.

Trends and Factors Affecting Our Future Results of Operations

We believe the principal factors that will affect our future results of operations are the economic, regulatory, political and governmental conditions that affect the shipping industry generally and that affect conditions in countries and markets in which our vessels engage in business. Please read “Risk Factors” in our 2017 Annual Report, filed with SEC on March 9, 2018, for a discussion of certain risks inherent in our business.

The accompanying interim condensed consolidated financial statements of Navios Midstream are unaudited, but, in the opinion of management, contain all adjustments necessary to present a fair statement of results, in all material respects, Navios Midstream’s condensed consolidated financial position as of June 30, 2018 and the condensed consolidated results of operations for the three and six month periods ended June 30, 2018 and 2017. The footnotes are condensed as permitted by the requirements for interim financial statements and, accordingly, do not include information and disclosures required under U.S. GAAP for complete financial statements. All such adjustments are deemed to be of a normal, recurring nature. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the full year. These financial statements should be read in conjunction with the consolidated financial statements and related notes included in Navios Midstream’s Annual Report on Form 20-F for the year ended December 31, 2017.

Period over Period Comparisons

For the Three Month Period ended June 30, 2018 compared to the Three Month Period ended June 30, 2017

Revenue: Revenue for the three month period ended June 30, 2018 increased by $2.3 million to $20.8 million, as compared to $18.5 million for the same period in 2017. The increase was mainly attributable to the increase in available days from 463 in the three month period ended June 30, 2017 to 517 days in the three month period ended June 30, 2018, due to certain prior period unscheduled off-hires among which the prolonged drydock of one of our vessels incurred in the three month period ended June 30, 2017. Time Charter Equivalent (“TCE”) was $39,578 for the three month period ended June 30, 2018 and $39,342 for the three month period ended June 30, 2017.

Time charter expenses: Time charter expenses were $0.3 million for each of the three month periods ended June 30, 2018 and 2017.

Direct vessel expenses:  Direct vessel expenses, comprised of the amortization of dry dock and special survey costs, of certain vessels in our fleet amounted to $1.0 million for each of the three month periods ended June 30, 2018 and 2017.

7

Management fees: Management fees amounted to $5.2 million for each of the three month periods ended June 30, 2018 and 2017.

General and administrative expenses: Total general and administrative expenses for the three month period ended June 30, 2018 increased by $0.2 million to $0.8 million, as compared to $0.6 million for the three month period ended June 30, 2017, due to a $0.2 million increase in legal and professional fees. The expenses charged by Navios Tankers Management Inc. (“the Manager”), a wholly-owned subsidiary of Navios Maritime Holdings Inc. (“Navios Holdings”), for administrative services were $0.4 million for each of the three month periods ended June 30, 2018 and 2017.

Depreciation and amortization: Depreciation and amortization for the three month period ended June 30, 2018 amounted to $5.7 million as compared to $6.3 million for the three month period ended June 30, 2017. The decrease is due to the sale of the Shinyo Kannika mitigated by the acquisition of the Nave Galactic in the first quarter of 2018. Depreciation of a vessel is calculated using an estimated useful life of 25 years for the date the vessel was originally delivered from the shipyard. Intangible assets are amortized over the contract periods, which extend up to 15.0 years at inception.

Interest expense and finance cost:  Interest expense and finance cost for the three month period ended June 30, 2018 amounted to $3.8 million as compared to $3.2 million for the three month period ended June 30, 2017. As of June 30, 2018 and 2017, the outstanding weighted average loan balance was $199.4 million and $201.4 million, respectively, and the weighted average interest rate was 6.72% for three month period ended June 30, 2018 as compared to 5.67% for the three month period ended June 30, 2017.

Operating surplus: Navios Midstream generated operating surplus for the three month period ended June 30, 2018 of $8.9 million as compared to $7.0 million for the three month period ended June 30, 2017. Operating Surplus is a non-GAAP financial measure used by certain investors to assist in evaluating a partnership’s ability to make quarterly cash distributions. (See “Reconciliation of EBITDA to Net Cash from Operating Activities, EBITDA, Operating Surplus” contained herein).

For the Six Month Period ended June 30, 2018 compared to the Six Month Period ended June 30, 2017

Revenue:  Revenue for the six month period ended June 30, 2018 increased by $1.0 million to $40.6 million, as compared to $39.6 million for the same period in 2017. The increase was mainly attributable to the increase in available days from 1,003 in the six month period ended June 30, 2017 to 1,039 days in the six month period ended June 30, 2018, due to certain prior period unscheduled off-hires among which the prolonged drydock of one of our vessels incurred in the three month period ended June 30, 2017. TCE was $38,535 for the six month period ended June 30, 2018 and $38,914 for the six month period ended June 30, 2017.

Time charter expenses:  Time charter expenses for the six month period ended June 30, 2018 were $0.5 million, as compared to $0.6 million for the six month period ended June 30, 2017.

Direct vessel expenses:  Direct vessel expenses, comprised of the amortization of dry dock and special survey costs, of certain vessels in our fleet amounted to $2.2 million for the six month period ended June 30, 2018, as compared to $1.8 million for the six month period ended June 30, 2017.

Management fees:  Management fees amounted to $10.3 million for each of the six month periods ended June 30, 2018 and 2017.

General and administrative expenses:  Total general and administrative expenses for the six month period ended June 30, 2018 increased by $0.3 million to $1.6 million, as compared to $1.4 million for the six month period ended June 30, 2017, due to an approximately $0.3 million increase in legal and professional fees. The expenses charged by the Manager for administrative services were $0.8 million for each of the six month periods ended June 30, 2018 and June 30, 2017, respectively.

Depreciation and amortization:  Depreciation and amortization for the six month period ended June 30, 2018 amounted to $11.9 million as compared to $12.6 million for the six month period ended June 30, 2017. The decrease is due to the sale of the Shinyo Kannika mitigated by the acquisition of the Nave Galactic in the first quarter of 2018. Depreciation of vessels is calculated using an estimated useful life of 25 years for the date the vessel was originally delivered from the shipyard. Intangible assets are amortized over the contract periods, which extend up to 15.0 years at inception.

8

Interest expense and finance cost:  Interest expense and finance cost for the six month period ended June 30, 2018 amounted to $7.2 million as compared to $6.3 million for the six month period ended June 30, 2017. For the six month periods ended June 30, 2018 and 2017, the outstanding weighted average loan balance was $199.6 million and $201.7 million, respectively, and the weighted average interest rate was 6.46% and 5.57%, respectively.

Loss on sale of Asset: On March 22, 2018, Navios Midstream sold the Shinyo Kannika to an unaffiliated third party for net cash proceeds of $16.2 million. The loss on sale of the vessel, upon write-off of the unamortized dry-docking, for the six month periods ended June 30, 2018 amounted to $32.4 million, as compared to $0 for the six month period ended June 30, 2017.

Other income/ (expense), net:  Other income, net for the six month period ended June 30, 2018 was $0.2 million, as compared to $0.3 million other expense, net for the six month period ended June 30, 2017.

Operating surplus:  Navios Midstream generated operating surplus for the six month period ended June 30, 2018 of $16.7 million as compared to $16.5 million for the same period ended June 30, 2017. Operating Surplus is a non-GAAP financial measure used by certain investors to assist in evaluating a partnership’s ability to make quarterly cash distributions. (See “Reconciliation of EBITDA to Net Cash from Operating Activities, EBITDA, Operating Surplus and Available Cash for Distribution” contained herein).

Liquidity and Capital Resources

Our primary short-term liquidity needs are to fund general working capital requirements, dry docking expenditures and debt repayment, and other obligations from time to time, while our long-term liquidity needs primarily relate to expansion and investment capital expenditures and other maintenance capital expenditures and debt repayment. Expansion capital expenditures are primarily for the purchase or construction of vessels to the extent the expenditures increase the operating capacity of or revenue generated by our fleet, while maintenance capital expenditures primarily consist of dry docking expenditures and expenditures to replace vessels in order to maintain the operating capacity of or revenue generated by our fleet. We anticipate that our primary sources of funds for our short-term liquidity needs will be cash flows from operations, proceeds from asset sales and bank borrowings, which we believe will be sufficient to meet our existing short-term liquidity needs for the next 12 months. Generally, our long-term sources of funds will be from cash from operations, long-term bank borrowings and other debt or equity financings. We expect that we will rely upon cash from operations and upon external financing sources, including bank borrowings, to fund acquisitions, expansion and investment capital expenditures and other commitments we have entered into. We cannot assure you that we will be able to secure adequate financing or obtaining additional funds on favorable terms, to meet our liquidity needs.

On July 29, 2016, Navios Midstream entered into a Sales Agreement with the Agent, pursuant to which Navios Midstream may issue and sell from time to time through the Agent common units representing limited partner interests having an aggregate offering price of up to $25.0 million.

There were no equity transactions or units sold under the Sales Agreement in the three and the six month periods ended June 30, 2018.

Credit Facilities

Term Loan B: On June 18, 2015, Navios Midstream and Navios Finance, as co-borrowers, completed the issuance of the $205.0 million Term Loan B. The Term Loan B is set to mature on June 18, 2020 and is repayable in equal quarterly installments of 0.25% of the initial principal amount of the Term Loan B, beginning on September 18, 2015, with a final payment of the aggregate principal amount of the Term Loan B, plus accrued and unpaid interest, due on maturity. The Term Loan B bears interest at LIBOR plus 4.50% per annum, is secured by first priority mortgages covering six vessels owned by subsidiaries of Navios Midstream, in addition to other collateral, and is guaranteed by such subsidiaries.

The Term Loan B requires maintenance of a loan to value ratio of no greater than 0.85 to 1.0 and a minimum interest coverage ratio of at least 3.75 to 1.0, and other restrictive covenants including restrictions on indebtedness, liens, acquisitions and investments, restricted payments and dispositions. The Term Loan B also provides for excess cash flow prepayments and customary events of default.

Following the acquisition of the Nave Galactic and the sale of the Shinyo Kannika, the Nave Galactic substituted the Shinyo Kannika under the Term Loan B.

As of June 30, 2018, an amount of $198.9 million was outstanding under this facility, as compared to $200.9 million for the same period in 2017. The weighted average interest rate for the six month periods ended June 30, 2018 and 2017 was 6.46% and 5.57%, respectively.

9

As of June 30, 2018, Navios Midstream was in compliance with the covenants set forth in the Term Loan B.

The following table presents cash flow information derived from the unaudited condensed consolidated statements of cash flows of Navios Midstream for the six month periods ended June 30, 2018 and 2017.

Cash provided by operating activities for the six month period ended June 30, 2018 as compared to the six month period ended June 30, 2017:

Net cash provided by operating activities increased by $18.1 million to $26.1 million for the six month period ended June 30, 2018 as compared to $8.0 million for the same period in 2017. The $18.1 million increase is analyzed as follows:

The net loss for the six month period ended June 30, 2018 was $25.3 million compared to $6.5 million net income for the six month period ended June 30, 2017. In determining net cash provided by operating activities for the six month period ended June 30, 2018, net loss was adjusted for the effect of loss on sale of asset of $32.4 million, depreciation and amortization of $11.9 million, $0.7 million for amortization of deferred financing cost and $2.2 million for the amortization of drydock and special survey costs. In determining net cash provided by operating activities for the six month period ended June 30, 2017, net income was adjusted for the effect of depreciation and amortization of $12.6 million, $0.7 million for amortization of deferred financing cost and $1.8 million for the amortization of drydock and special survey costs.

Amounts due from related parties as of June 30, 2018 and December 31, 2017 was $15.0 million and $22.7 million, respectively, which mainly related to the backstop commitment from Navios Acquisition, as well as, payments of management fees and other expenses including dry docking expenses to the Manager in accordance with our Management Agreement. See “Item 7.—Major Unitholders and Related Party Transactions,” included in the 2017 Annual Report.

Accounts receivable decreased by $0.4 million for the six month period ended June 30, 2018, due to the decrease in receivables from charterers.

Accounts payable increased by $0.1 million for the six month period ended June 30, 2018. This increase was attributable to the increase in broker’s and supplier’s expenses and other payable.

Prepaid expenses and other current assets decreased by $0.4 million for the six month period ended June 30, 2018.

Cash used in investing activities for the six month period ended June 30, 2018 as compared to the six month period ended June 30, 2017:

Net cash used in investing activities was $28.7 million for the six month period ended June 30, 2018 as compared to no cash used in investing activities for the same period in 2017.

Net cash used in investing activities for the six month period ended June 30, 2018, resulted from $45.0 million paid for the acquisition of the Nave Galactic, partially mitigated by $16.2 million net proceeds from sale of the Shinyo Kannika.

10

Cash used in financing activities for the six month period ended June 30, 2018 as compared to the six month period ended June 30, 2017:

Net cash used in financing activities for the six month period ended June 30, 2018 was $12.7 million, compared to $15.0 million net cash used in financing activities for the six month period ended June 30, 2017. Net cash used in financing activities for the six month period ended June 30, 2018 primarily resulted from: (a) $11.7 million of dividends paid; and (b) $1.0 million of loan repayments. Net cash used in financing activities for the six month period ended June 30, 2017 primarily resulted from: (a) $18.0 million of dividends paid; and (b) $1.0 million of loan repayments, partially mitigated by: (i) $4.0 million of proceeds from the issuance of common units; and (ii) $0.1 million of proceeds from the issuance of general partner units.

EBITDA and Adjusted EBITDA

EBITDA and Adjusted EBITDA are non-U.S. GAAP financial measures and should not be used in isolation or as substitution for Navios Midstream’s results calculated in accordance with U.S. GAAP.

11

EBITDA represents net (loss)/income before interest and finance costs, before depreciation and amortization and before income taxes. Adjusted EBITDA in this document represents EBITDA excluding loss on sale of vessel. We use Adjusted EBITDA as liquidity measure and reconcile EBITDA and Adjusted EBITDA to net cash provided by/ (used in) operating activities, the most comparable U.S. GAAP liquidity measure. EBITDA in this document is calculated as follows: net cash provided by/(used in) operating activities adding back, when applicable and as the case may be, the effect of: (i) net increase/(decrease) in operating assets; (ii) net (increase)/decrease in operating liabilities; (iii) net interest cost; (iv) amortization of deferred finance costs and other related expenses; and (v) gain/ loss on sale of assets. Navios Midstream believes that EBITDA and Adjusted EBITDA are each the basis upon which liquidity can be assessed and present useful information to investors regarding Navios Midstream’s ability to service and/or incur indebtedness, pay capital expenditures, meet working capital requirements and pay dividends. Navios Midstream also believes that EBITDA and Adjusted EBITDA are used: (i) by potential lenders to evaluate potential transactions; (ii) to evaluate and price potential acquisition candidates; and (iii) by securities analysts, investors and other interested parties in the evaluation of companies in our industry.

EBITDA and Adjusted EBITDA have limitations as an analytical tool, and should not be considered in isolation or as a substitute for the analysis of Navios Midstream’s results as reported under U.S. GAAP. Some of these limitations are: (i) EBITDA and Adjusted EBITDA do not reflect changes in, or cash requirements for, working capital needs; and (ii) although depreciation and amortization are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future. EBITDA and Adjusted EBITDA do not reflect any cash requirements for such capital expenditures. Because of these limitations, EBITDA and Adjusted EBITDA should not be considered as a principal indicator of Navios Midstream’s performance. Furthermore, our calculation of EBITDA and Adjusted EBITDA may not be comparable to that reported by other companies due to differences in methods of calculation.

EBITDA increased by approximately $2.3 million to $14.7 million for the three month period ended June 30, 2018, as compared to $12.4 million for the same period in 2017. The increase in EBITDA was mainly due to the $2.3 million increase in revenue.

EBITDA for the six month period ended June 30, 2018, was affected by a $32.4 million book loss on the sale of the Shinyo Kannika. Excluding this item, Adjusted EBITDA for the six month period ended June 30, 2018, was $28.4 million compared to $27.1 million for the same period in 2017. The increase in Adjusted EBITDA by $1.3 million was due to a: (a) $1.0 million increase in revenue; (b) $0.5 million increase in other income/(expense), net; and (c) $0.1 million decrease in management fees; partially mitigated by a $0.3 million increase in general and administrative expenses.

Operating Surplus

Operating Surplus represents net income adjusted for depreciation and amortization expense, non-cash interest expense and estimated maintenance and replacement capital expenditures. Maintenance and replacement capital expenditures are those capital expenditures required to maintain over the long term the operating capacity of, or the revenue generated by, Navios Midstream’s capital assets.

Operating Surplus is a quantitative measure used in the publicly-traded partnership investment community to assist in evaluating a partnership’s ability to make quarterly cash distributions. Operating Surplus is not required by U.S. GAAP and should not be considered a substitute for net income, cash flow from operating activities and other operations or cash flow statement data prepared in accordance with U.S. GAAP or as a measure of profitability or liquidity.

Available Cash

Available Cash generally means, for each fiscal quarter, all cash on hand at the end of the quarter:

Available Cash is a quantitative measure used in the publicly traded partnership investment community to assist in evaluating a partnership’s ability to make quarterly cash distributions. Available Cash is not required by U.S. GAAP and should not be considered a substitute for net income, cash flow from operating activities and other operations or cash flow statement data prepared in accordance with U.S. GAAP or as a measure of profitability or liquidity.

Borrowings

Navios Midstream’s long-term third party borrowings are reflected in its balance sheet as “Long-term debt, net of deferred finance costs and discount”. As of June 30, 2018 and December 31, 2017, the loan balance outstanding amounted to $198.9 million and $199.9 million, respectively, under the Term Loan B, discussed above. The current portion of long-term debt amounted to $2.1 million for each of the periods ended June 30, 2018 and December 31, 2017.

Capital Expenditures

Maintenance for our vessels and expenses related to drydocking are paid to the Manager at cost under the Management Agreement.

Maintenance and replacement capital expenditures

Our partnership agreement requires our Board of Directors to deduct from operating surplus each quarter estimated maintenance and replacement capital expenditures, as opposed to actual maintenance and replacement capital expenditures, in order to reduce disparities in operating surplus caused by fluctuating maintenance and replacement capital expenditures, such as drydocking and vessel replacement. The actual cost of replacing the vessels in our fleet will depend on a number of factors, including prevailing market conditions, hire rates and the availability and cost of financing at the time of replacement. Our Board of Directors, with the approval of the conflicts committee, may determine that one or more of our assumptions should be revised, which could cause our Board of Directors to increase the amount of estimated maintenance and replacement capital expenditures. We may elect to finance some or all of our maintenance and replacement capital expenditures through the issuance of additional common units, which could be dilutive to our existing unitholders. We must make substantial capital expenditures to maintain the operating capacity of our fleet, which will reduce cash available for distribution. In addition, each quarter we are required to deduct estimated maintenance and replacement capital expenditures from operating surplus, which may result in less cash available to unitholders than if actual maintenance and replacement capital expenditures were deducted.

Maintenance Capital Expenditures . Our annual estimated drydocking capital expenditure reserve is expected to be $1.9 million. The estimation was based on assumptions and estimates regarding the remaining useful lives of the vessels, a relative net investment rate, and drydocking and special survey costs based on current industry data.

Replacement Capital Expenditures . Because of the substantial capital expenditures we are required to make to maintain our fleet over time, our initial annual estimated replacement capital expenditures for estimating maintenance and replacement capital expenditures is expected to be $8.6 million per year, for replacing vessels at the end of their useful lives. The future vessel replacement is based on assumptions and estimates regarding the remaining useful lives of the vessels, a relative net investment rate, vessel replacement values based on current market conditions and residual value of the vessels at the end of their useful lives based on current steel prices.

Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements that have or are reasonably likely to have, a current or future material effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

13

Cash Distribution Policy

Our cash distribution policy is consistent with the terms of our partnership agreement, which requires that we distribute all of our available cash quarterly (after deducting expenses, including estimated maintenance and replacement capital expenditures and reserves).

Limitations on Cash Distributions and Our Ability to Change Our Cash Distribution Policy

There is no guarantee that unitholders will receive quarterly distributions from us. Our distribution policy is subject to certain restrictions and may be changed at any time, including:

14

Our ability to make distributions to our unitholders depends on the performance of our subsidiaries and their ability to distribute funds to us. The ability of our subsidiaries to make distributions to us 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.

Quarterly Distribution

In general, our general partner is entitled to 2.0% of all distributions that we make prior to our liquidation. The general partner’s initial 2.0% interest in these distributions may, however, be reduced if we issue additional units in the future and our general partner does not contribute a proportionate amount of capital to us to maintain its initial 2.0% general partner interest. Our general partner has the right, but not the obligation, to contribute a proportionate amount of capital to us to maintain its current general partner interest.

On January 22, 2018, the Board of Directors authorized a 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 $9.0 million.

On April 26, 2018, the Board of Directors authorized a 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 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 $2.7 million.

On July 24, 2018, the Board of Directors authorized a quarterly cash distribution for the three month period ended June 30, 2018 of $0.125 per unit. The distribution is payable on August 14, 2018 to all holders of record holders of common units and general partner units on August 6, 2018. The aggregate amount of the declared distribution is anticipated to be $2.7 million.

Incentive Distribution Rights

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 our partnership agreement.

The following table illustrates the percentage allocations of the additional available cash from operating surplus among the unitholders and our general partner up to the various target distribution levels. The amounts set forth under “Marginal Percentage Interest in Distributions” are the percentage interests of the unitholders and our general partner in any available cash from operating surplus we distribute up to and including the corresponding amount in the column “Total Quarterly Distribution Target Amount,” until available cash from operating surplus we distribute reaches the next target distribution level, if any. The percentage interests shown for the unitholders and our general partner for the minimum quarterly distribution are also applicable to quarterly distribution amounts that are less than the minimum quarterly distribution. The percentage interests shown for our general partner assume that our general partner maintains its 2.0% general partner interest and assume our general partner has not transferred the incentive distribution rights.

On November 16, 2017, the subordination period, as defined in our partnership agreement of Navios Midstream expired, resulting in the conversion of the 9,342,692 subordinated units into common units. Any future cash distributions will be made in accordance with the terms in our partnership agreement applicable to the periods following the subordination period.

On June 18, 2018, in accordance with the terms of our 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.

Amounts due from related parties mainly consisted of the backstop commitment from Navios Acquisition (see “Backstop agreements” paragraph below), as well as special survey and dry docking expenses for certain vessels of our fleet, and management fees in accordance with the Management Agreement.

Omnibus agreement: On November 18, 2014, Navios Midstream entered into an omnibus agreement, with Navios Acquisition, Navios Holdings and Navios Maritime Partners L.P. (“Navios Partners”) in connection with the Navios Midstream IPO, pursuant to which Navios Acquisition, Navios Holdings, Navios Partners and their controlled affiliates generally have agreed not to acquire or own any VLCCs, crude oil tankers, refined petroleum product tankers, LPG tankers or chemical tankers under time charters of five or more years. The omnibus agreement contains significant exceptions that will allow Navios Acquisition, Navios Holdings, Navios Partners or any of their controlled affiliates to compete with Navios Midstream under specified circumstances.

Under the omnibus agreement, Navios Midstream and its subsidiaries granted to Navios Acquisition a right of first offer on any proposed sale, transfer or other disposition of any of its VLCCs or any crude oil tankers, refined petroleum product tankers, LPG tankers or chemical tankers and related charters owned or acquired by Navios Midstream. Likewise, Navios Acquisition granted a similar right of first offer to Navios Midstream for any of the VLCCs, crude oil tanker, refined petroleum product tanker, LPG tanker or chemical tanker under charter for five or more years it might own. These rights of first offer will not apply to a (a) sale, transfer or other disposition of vessels between any affiliated subsidiaries, or pursuant to the terms of any charter or other agreement with a charter party or (b) merger with or into, or sale of substantially all of the assets to, an unaffiliated third-party.

Navios Midstream entered into an omnibus agreement with Navios Maritime Containers Inc. (“Navios Containers”), Navios Acquisition, Navios Holdings and Navios Partners, pursuant to which Navios Acquisition, Navios Holdings, Navios Partners and Navios Midstream have granted to Navios Containers a right of first refusal over any container vessels to be sold or acquired in the future. The omnibus agreement contains significant exceptions that will allow Navios Acquisition, Navios Holdings, Navios Partners and Navios Midstream to compete with Navios Containers under specified circumstances.

Backstop agreements: 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 $35,000 per day for the Nave Celeste, $38,000 per day for the Shinyo Ocean and $38,000 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. The backstop commitment for the Shinyo Kannika was terminated in relation to the sale of this vessel in March 2018. Navios Acquisition agreed to extend the backstop commitment of the Shinyo Kannika to the Nave Galactic, following the acquisition of the latter from Navios Acquisition in March 2018. For the three and six month periods ended June 30, 2018 backstop revenue amounted to $5.7 million and $10.6 million, respectively and was included in the balance due from related parties (see “Balances due from related parties” paragraph above). For the three and six month periods ended June 30, 2017 backstop commitment was $4.1 million and $5.2 million, respectively and was included in the balance due from related parties (see “Balances due from related parties” paragraph above).

Option vessels: Navios Midstream has options expiring on November 18, 2018 to acquire the Nave Buena Suerte, the Nave Neutrino and the Nave Electron from Navios Acquisition.

Quantitative and Qualitative Disclosures about Market Risks

Foreign Exchange Risk

Our functional and reporting currency is the U.S. dollar. We engage in worldwide commerce with a variety of entities. Although our operations may expose us to certain levels of foreign currency risk, our transactions are predominantly U.S. dollar denominated. Transactions in currencies other than U.S. dollar are translated at the exchange rate in effect at the date of each transaction. Differences in exchange rates during the period between the date a transaction denominated in a foreign currency is consummated and the date on which it is either settled or translated, are recognized. Expenses incurred in foreign currencies against which the U.S. dollar falls in value can increase thereby decreasing our income or vice versa if the U.S. dollar increases in value.

17

Interest Rate Risk

Borrowings under our credit facility bear interest at rates based on a premium over U.S. $ LIBOR except for the interest rate on the Notes, which is fixed. Therefore, we are exposed to the risk that our interest expense may increase if interest rates rise. For the six month period ended June 30, 2018, we paid interest on our outstanding debt at a weighted average interest rate of 6.46%. A 1% increase in LIBOR would have increased our interest expense for the six month period ended June 30, 2018 by $1.0 million. For the six month period ended June 30, 2017, we paid interest on our outstanding debt at a weighted average interest rate of 5.57%.

Concentration of Credit Risk

Financial instruments, which potentially subject us to significant concentrations of credit risk, consist principally of trade accounts receivable. We closely monitor our exposure to customers for credit risk. We have policies in place to ensure that we trade with customers with an appropriate credit history. For the six month period ended June 30, 2018, customers representing 10% or more of our total revenue were Cosco Dalian, VL8 and SK Shipping that accounted for 43.5%, 17.0% and 13.4%, respectively, of our revenue.

For the six month period ended June 30, 2017, customers representing 10% or more of our total revenue were Cosco Dalian, VL8 and Shell Tankers Singapore Private Limited that accounted for 48.4%, 17.6% and 11.5%, respectively, of our revenue.

Inflation

Inflation has had a minimal impact on vessel operating expenses and general and administrative expenses. Our management does not consider inflation to be a significant risk to direct expenses in the current and foreseeable economic environment.

Critical Accounting Policies

Our interim condensed consolidated financial statements have been prepared in accordance with U.S. GAAP. The preparation of these financial statements requires us to make estimates in the application of our accounting policies based on the best assumptions, judgments and opinions of management. Following is a discussion of the accounting policies that involve a higher degree of judgment and the methods of their application that affect the reported amount of assets and liabilities, revenues and expenses and related disclosure of contingent assets and liabilities at the date of our financial statements. Actual results may differ from these estimates under different assumptions or conditions.

Critical accounting policies are those that reflect significant judgments or uncertainties, and potentially result in materially different results under different assumptions and conditions. For a description of all of our significant accounting policies, see Note 2.

(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:

(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.

CONDENSED NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

(Expressed in thousands of U.S. Dollars except unit and per unit data)

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.

(Expressed in thousands of U.S. Dollars except unit and per unit data)

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.

The bank accounts are legally owned by the entities referenced in Note 1.

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

Restricted cash as of June 30, 2018 decreased by $10,000 as compared to December 31, 2017, which was used for the acquisition of the Nave Galactic.

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.

NOTE 9: COMMITMENTS AND CONTINGENCIES

The Company is involved in various disputes and arbitration proceedings arising in the ordinary course of business. Provisions are recognized in the financial statements for all such proceedings where the Company believes that a liability may be probable, and for which the amounts are reasonably estimable, based upon facts known at the date of the financial statements were prepared. In the opinion of the management, the ultimate disposition of these matters individually and in aggregate will not materially affect the Company’s financial position, results of operations or liquidity.

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.
