Summary of Significant Accounting Policies	NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Summary of Significant Accounting Policies Basis of presentation Reverse Stock Split: On April 25, 2019, the Company’s unitholders approved a 1-for-15 reverse stock split 164.7 11 983 Principles of consolidation Navios Partners also consolidates entities that are determined to be variable interest entities (“VIE”) as defined in the accounting guidance, if it determines that it is the primary beneficiary. A VIE is defined as a legal entity where either (i) equity interest holders as a group lack the characteristics of a controlling financial interest, including decision making ability and an interest in the entity’s residual risks and rewards, (ii) the equity holders have not provided sufficient equity investment to permit the entity to finance its activities without additional subordinated financial support, or (iii) the voting rights of some investors are not proportional to their obligations to absorb the expected losses of the entity, their rights to receive the expected residual returns of the entity, or both and substantially all of the entity’s activities either involve or are conducted on behalf of an investor that has disproportionately few voting rights. Based on internal forecasts and projections that take into account reasonably possible changes in our trading performance, management believes that the Company has adequate financial resources to continue in operation and meet its financial commitments, including but not limited to capital expenditures and debt service obligations, for a period of at least twelve months from the date of issuance of these consolidated financial statements. Accordingly, the Company continues to adopt the going concern basis in preparing its financial statements.

Consideration is given to: (i) the length of time and the extent to which the fair value has been less than the carrying value; (ii) the financial condition and near-term prospects of Navios Containers; and (iii) the intent and ability of the Company to retain its investment in Navios Containers, for a period of time sufficient to allow for any anticipated recovery in fair value (see Note 14 – Investment in Affiliates). Revenue and Expense Recognition 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 has elected to early adopt the requirements of ASU 2016-02 effective January 1, 2018, using the modified retrospective method which is consistent with the approach the Company has elected under the new revenue standard, and elected to apply the additional optional transition method along with the following practical expedients: a package of practical expedients which does not require the Company to reassess: (1) whether any expired or existing contracts are or contain leases; (2) lease classification for any expired or existing leases; and (3) whether initial direct costs for any expired or existing leases would qualify for capitalization under ASC 842. The Company’s contract revenues from time chartering and pooling arrangements are governed by ASU 2016-02 (ASC 842) “Leases”. Upon adoption of ASC 606 and ASC 842, the timing and recognition of earnings from the pool arrangements and time charter contracts to which the Company is party did not change from previous practice. The Company has determined to recognize lease revenue as a combined single lease component for all time charters (operating leases) as the related lease component and non lease components will have the same timing and pattern of the revenue recognition of the combined single lease component. The performance obligations in a time charter contract are satisfied over term of the contract beginning when the vessel is delivered to the charterer until it is redelivered back to the Company. As a result of the adoption of these standards, there was no effect on the Company’s retained earnings, as at January 1, 2018. Revenue from time chartering Revenues from time chartering of vessels are accounted for as operating leases and are thus recognized on a straight line basis as the average lease 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. Short period charters for less than three months are referred to as spot-charters. Charters extending three months to a year are generally referred to as medium-term charters. All other charters are considered long-term. Under time charters, operating costs such as for crews, maintenance and insurance are typically paid by the owner of the vessel. Revenue from time chartering of vessels amounted to $ 45,679 45,450 91,328 88,979 Revenue from voyage contracts The Company’s revenues earned under voyage contracts (revenues for the transportation of cargo) were previously recognized ratably over the estimated relative transit time of each voyage. A voyage was deemed to commence when a vessel was available for loading and was deemed to end upon the completion of the discharge of the current cargo. Estimated losses on voyages are provided for in full at the time such losses become evident. Under a voyage charter, a vessel is provided for the transportation of specific goods between specific ports in return for payment of an agreed upon freight per ton of cargo. Upon adoption of ASC 606, the Company recognizes revenue ratably from port of loading to when the charterer’s cargo is discharged as well as defer costs that meet the definition of “costs to fulfill a contract” and relate directly to the contract. During 2017, no freight voyage existed and therefore, there was no impact on the Company’s retained earnings as at January 1, 2018. Revenue from voyage contracts amounted to $ 306 3,808 Pooling arrangements 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 points 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 as variable rate operating leases 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. The allocation of such net revenue may be subject to future adjustments by the pool however, such changes are not expected to be material. The Company recognizes net pool revenue on a monthly and quarterly basis, when the vessel has participated in a pool during the period and the amount of pool revenue can be estimated reliably based on the pool report. Revenue from vessels operating in pooling arrangements amounted to $ 1,405 1,776 Revenue from profit-sharing Profit-sharing revenues are calculated at an agreed percentage of the excess of the charterer’s average daily income (calculated on a quarterly or half-yearly basis) over an agreed amount and accounted for on an accrual basis based on provisional amounts and for those contracts that provisional accruals cannot be made due to the nature of the profit sharing elements, these are accounted for on the actual cash settlement or when such revenue becomes determinable. Profit sharing revenue amounted to $ 0 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 or freight rate. Since address commissions represent a discount (sales incentive) on services rendered by the Company and no identifiable benefit is received in exchange for the consideration provided to the charterer, these commissions are presented as a reduction of revenue. Recent Accounting Pronouncements In March 2020, the FASB issued ASU 2020-4, “Reference Rate Reform (Topic 848)” (“ASU 2020-4”), which provides optional guidance intended to ease the potential burden in accounting for the expected discontinuation of LIBOR as a reference rate in the financial markets. The guidance can be applied to modifications made to certain contracts to replace LIBOR with a new reference rate. The guidance, if elected, will permit entities to treat such modifications as the continuation of the original contract, without any required accounting reassessments or remeasurements. The ASU 2020-4 was effective for the Company beginning on March 12, 2020 and the Company will apply the amendments prospectively through December 31, 2022. There was no impact to the Company’s unaudited condensed consolidation financial statements as a result of adopting this standard update. Currently, the Company has various contracts that reference LIBOR and is assessing how this standard may be applied to specific contract modifications. In October 2018, the Financial Accounting Standards Board (“FASB”) issued ASU 2018-17, Consolidation (Topic 810): “Targeted Improvements to Related Party Guidance for Variable Interest Entities” (“ASU 2018-17”). ASU 2018-17 provides that indirect interests held through related parties in common control arrangements should be considered on a proportional basis for determining whether fees paid to decision makers and service providers are variable interests. This is consistent with how indirect interests held through related parties under common control are considered for determining whether a reporting entity must consolidate a VIE. For public business entities the amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The adoption of this new accounting guidance did not have a material effect on the Company’s consolidated financial statements. In August 2018, FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement”. This update modifies the disclosure requirements on fair value measurements. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, and earlier adoption is permitted. The adoption of this new accounting guidance did not have a material effect on the Company’s consolidated financial statements. In June 2016, FASB issued ASU No. 2016-13, “Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”. This standard requires entities to measure all expected credit losses of financial assets held at a reporting date based on historical experience, current conditions, and reasonable and supportable forecasts in order to record credit losses in a more timely manner. ASU 2016-13 also amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The standard is effective for interim and annual reporting periods beginning after December 15, 2019, although early adoption is permitted for interim and annual periods beginning after December 15, 2018. In November 2018, FASB issued ASU 2018-19 “Codification Improvements to topic 326, Financial Instruments-Credit Losses”. The amendments in this update clarify that operating lease receivables are not within the scope of ASC 326-20 and should instead be accounted for under the new leasing standard, ASC 842. In April 2019, FASB issued ASU 2019-04 “Codification Improvements to topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments”. In May 2019, FASB issued ASU 2019-05, “Financial Instruments-Credit Losses (Topic 326): Targeted Transition Relief”. The amendments in this update provide entities that have certain instruments within the scope of Subtopic 326-20, Financial Instruments-Credit Losses-Measured at Amortized Cost, with an option to irrevocably elect the fair value option in Subtopic 825-10, Financial Instruments-Overall, applied on an instrument-by-instrument basis for eligible instruments, upon adoption of Topic 326. The fair value option election does not apply to held-to-maturity debt securities. An entity that elects the fair value option should subsequently apply the guidance in Subtopics 820-10, Fair Value Measurement-Overall, and 825-10. In November 2019, FASB issued ASU No. 2019-11, Codification Improvements to Topic 326, Financial Instruments-Credit Losses. This update introduced an expected credit loss model for the impairment of financial assets measured at amortized cost basis. That model replaces the probable, incurred loss model for those assets. The standard is effective for interim and annual reporting periods beginning after December 15, 2019. The Company has assessed all the expected credit losses of its financial assets and the adoption of this ASU did not have a material impact on the Company’s consolidated financial statements.

The impact of the COVID-19 pandemic continues to unfold and may continue to have negative effect on our business, financial performance and the results of our operations, including due to decreased demand for global seaborne dry bulk and container trade and dry bulk and containership charter rates, the extent of which will depend largely on future developments. As a result, many of our estimates and assumptions required increased judgment and carry a higher degree of variability and volatility. As events continue to evolve and additional information becomes available, our estimates may change in future periods. We have evaluated the impact of current economic situation on the recoverability of the carrying amount of our vessels. As of June 30, 2020, we concluded that events and circumstances triggered the existence of potential impairment of our vessels. These indicators included volatility in the charter market as well as the potential impact the current marketplace may have on our future operations. As a result, we performed step one of the impairment assessment of our vessels by comparing the undiscounted projected net operating cash flows for each vessel to its carrying value.As of June 30, 2020, our assessment concluded that step two of the impairment analysis was required for three containerships held and used, as the undiscounted projected net operating cash flows did not exceed the carrying value. As a result, the Company recorded an impairment loss of $ 6,800 2019 As of December 31, 2019, our assessment concluded that step two of the impairment analysis was required for one of our vessels held and used, as the undiscounted projected net operating cash flows did not exceed the carrying value. As a result, the Company recorded an impairment loss of $ 29,335 On March 21, 2019, Navios Partners entered into a Memorandum of Agreement with an unrelated third party for the disposal of the Navios Galaxy I for a net sale price of $ 5,978 7,345

Segment Information	NOTE 9 – SEGMENT INFORMATION Segment Information Navios Partners reports financial information and evaluates its operations by charter revenues. Navios Partners does not use discrete financial information to evaluate operating results for each type of charter or by sector. As a result, management reviews operating results solely by revenue per day and operating results of the fleet and thus Navios Partners has determined that it operates under one reportable segment. The following table sets out operating revenue by geographic region for Navios Partners’ reportable segment. Revenue is allocated on the basis of the geographic region in which the customer is located. Drybulk and containerships operate worldwide. Revenues from specific geographic region, which contribute over 10% of total revenue, are disclosed separately. Revenue by Geographic Region 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.

Income Taxes	NOTE 10 – INCOME TAXES Income Taxes Marshall Islands, Malta and Liberia do not impose a tax on international shipping income. Under the laws of Marshall Islands, Malta and Liberia, the countries of the vessel-owning subsidiaries’ incorporation and vessels’ registration, the vessel-owning subsidiaries are subject to registration and tonnage taxes, which have been included in vessel operating expenses in the accompanying condensed Consolidated Statements of Operations. 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 vessel’s 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 the vessel-owning subsidiaries satisfy these initial criteria. In addition, these companies must meet an ownership test. The management of Navios Partners believes that this ownership test was satisfied prior to the IPO by virtue of a special rule applicable to situations where the ship operating companies are beneficially owned by a publicly traded company. Although not free from doubt, management also believes that the ownership test will be satisfied based on the trading volume and ownership of Navios Partners’ units, but no assurance can be given that this will remain so in the future.

Cash Distributions And Earnings Per Unit
Cash Distributions and Earnings per Unit	NOTE 15 – CASH DISTRIBUTIONS AND EARNINGS PER UNIT Cash Distributions and Earnings per Unit There is no guarantee that Navios Partners will pay a quarterly distribution on the common and general partner units in any quarter. On February 3, 2016, Navios Partners announced that its Board of Directors decided to suspend the quarterly cash distributions to its unitholders, including the distribution for the quarter ended December 31, 2015. In March 2018, the board determined to reinstate a distribution and any continued distribution will be at the discretion of our Board of Directors, taking into consideration the terms of its partnership agreement. The Company is prohibited from making any distributions to unitholders if it would cause an event of default, or an event of default exists, under its existing credit facilities. There is incentive distribution rights held by the General Partner, which are analyzed as follows: Cash Distributions and Earnings per Unit - Percentage Interest in Distributions Marginal Percentage Interest in Distributions Total Quarterly Distribution Target Amount Common Unitholders Incentive General Partner Minimum Quarterly Distribution up to $ 5.25 98 % — 2 % First Target Distribution up to $ 6.0375 98 % — 2 % Second Target Distribution above $ 6.0375 6.5625 85 % 13 % 2 % Third Target Distribution above $ 6.5625 7.875 75 % 23 % 2 % Thereafter above $ 7.875 50 % 48 % 2 % The first 98% of the quarterly distribution is paid to all common unitholders. The incentive distributions rights (held by the General Partner) apply only after a minimum quarterly distribution of $6.0375.

Basic earnings/(losses) per unit is determined by dividing net income/(loss) attributable to Navios Partners common unitholders by the weighted average number of common units outstanding during the period. Diluted earnings per unit is calculated in the same manner as basic earnings per unit, except that the weighted average number of outstanding units increased to include the dilutive effect of outstanding unit options or phantom units. Net loss per unit undistributed is determined by taking the distributions in excess of net income and allocating between common units and general partner units on a 98 2 The calculations of the basic and diluted earnings per unit are presented below.

Leases
Leases	NOTE 18 – LEASES Leases Effective January 1, 2018 the Company elected to early adopt the requirements of Accounting Standard Update (“ASU”) 2016-02, “Leases (Topic 842)”. Under the new lease standard, lessees are required to recognize a right-of-use asset and a lease liability for substantially all leases. The new lease standard continues to classify leases as either financing or operating, with classification affecting the pattern of expense recognition. The accounting applied by a lessor under the new guidance is substantially equivalent to the previous lease accounting guidance. The following are the type of contracts that fall under ASC 842: Time charter out contracts and pooling arrangements The Company’s contract revenues from time chartering and pooling arrangements are governed by ASC 842. Upon adoption of ASC 842, the timing and recognition of earnings from the time charter contracts and pool arrangements to which the Company is party did not change from previous practice. For further analysis, refer to Note 2 - Bareboat charter-in contract On July 24, 2019, Navios Partners took delivery of the Navios Libra 2019 Kamsarmax 82,011 6 Based on management estimates and market conditions, the lease term of this lease is being assessed at each balance sheet date. At lease commencement, the Company determines a discount rate to calculate the present value of the lease payments so that it can determine lease classification and measure the lease liability. In determining the discount rate to be used at lease commencement, the Company used its incremental borrowing rate as there was no implicit rate included in charter-in contracts that can be readily determinable. The incremental borrowing rate is the rate that reflects the interest a lessee would have to pay to borrow funds on a collateralized basis over a similar term and in a similar economic environment. The Company then applied the respective incremental borrowing rate based on the remaining lease term of the specific lease. As of July 24, 2019, Navios Partners’ incremental borrowing rate was approximately 7 As of June 30, 2020 and December 31, 2019 the unamortized balance of the lease liability amounted $ 13,697 14,201 13,782 14,241 The Company recognizes the lease payments for its operating leases as charter hire expense on the condensed consolidated statements of operations on a straight-line basis over the lease term. Lease expense for each of the three and six month periods ended June 30, 2020 amounted to $ 541 1,083 0 The table below provides the total amount of lease payments on an undiscounted basis on our chartered-in contracts as of June 30, 2020: Leases Charter-in vessels in operation June 30, 2021 $ 2,172 June 30, 2022 2,172 June 30, 2023 2,087 June 30, 2024 2,086 June 30, 2025 2,081 June 30, 2026 and thereafter 8,191 Total $ 18,789 Operating lease liabilities, including current portion $ 13,697 Discount based on incremental borrowing rate $ 5,092 Sale and Lease Back Agreements During 2019 and 2018 the Company has entered into sale and leaseback agreements with unrelated third parties for five vessels of the Company’s fleet. Navios Partners has purchase obligations to acquire the vessels at the end of the lease terms, consequently under ASC 842-40 the transfers of the vessels were determined to be failed sales and were treated as financing transactions. The vessels were not derecognized and continue to be depreciated over their respective useful lives, and tested for impairment as per Company’s policy (see Note 6—Borrowings).

Principles of consolidation	Principles of consolidation Navios Partners also consolidates entities that are determined to be variable interest entities (“VIE”) as defined in the accounting guidance, if it determines that it is the primary beneficiary. A VIE is defined as a legal entity where either (i) equity interest holders as a group lack the characteristics of a controlling financial interest, including decision making ability and an interest in the entity’s residual risks and rewards, (ii) the equity holders have not provided sufficient equity investment to permit the entity to finance its activities without additional subordinated financial support, or (iii) the voting rights of some investors are not proportional to their obligations to absorb the expected losses of the entity, their rights to receive the expected residual returns of the entity, or both and substantially all of the entity’s activities either involve or are conducted on behalf of an investor that has disproportionately few voting rights. Based on internal forecasts and projections that take into account reasonably possible changes in our trading performance, management believes that the Company has adequate financial resources to continue in operation and meet its financial commitments, including but not limited to capital expenditures and debt service obligations, for a period of at least twelve months from the date of issuance of these consolidated financial statements. Accordingly, the Company continues to adopt the going concern basis in preparing its financial statements.

(12) Vessels under the sale and leaseback transaction (see Note 18 – Leases). (13) The vessels were acquired on June 29, 2020, following the liquidation of Navios Europe II (see Note 4 – Vessels, net). Investments in Affiliates: Affiliates included in the financial statements accounted for under the equity method: 33.5 5 Navios Partners evaluates its investments in Navios Europe II (until its liquidation) and Navios Containers for other than temporary impairment (“OTTI”) on a quarterly basis. Consideration is given to: (i) the length of time and the extent to which the fair value has been less than the carrying value; (ii) the financial condition and near-term prospects of Navios Containers; and (iii) the intent and ability of the Company to retain its investment in Navios Containers, for a period of time sufficient to allow for any anticipated recovery in fair value (see Note 14 – Investment in Affiliates).
Revenue and Expense Recognition	Revenue and Expense Recognition 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 has elected to early adopt the requirements of ASU 2016-02 effective January 1, 2018, using the modified retrospective method which is consistent with the approach the Company has elected under the new revenue standard, and elected to apply the additional optional transition method along with the following practical expedients: a package of practical expedients which does not require the Company to reassess: (1) whether any expired or existing contracts are or contain leases; (2) lease classification for any expired or existing leases; and (3) whether initial direct costs for any expired or existing leases would qualify for capitalization under ASC 842. The Company’s contract revenues from time chartering and pooling arrangements are governed by ASU 2016-02 (ASC 842) “Leases”. Upon adoption of ASC 606 and ASC 842, the timing and recognition of earnings from the pool arrangements and time charter contracts to which the Company is party did not change from previous practice. The Company has determined to recognize lease revenue as a combined single lease component for all time charters (operating leases) as the related lease component and non lease components will have the same timing and pattern of the revenue recognition of the combined single lease component. The performance obligations in a time charter contract are satisfied over term of the contract beginning when the vessel is delivered to the charterer until it is redelivered back to the Company. As a result of the adoption of these standards, there was no effect on the Company’s retained earnings, as at January 1, 2018. Revenue from time chartering Revenues from time chartering of vessels are accounted for as operating leases and are thus recognized on a straight line basis as the average lease 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. Short period charters for less than three months are referred to as spot-charters. Charters extending three months to a year are generally referred to as medium-term charters. All other charters are considered long-term. Under time charters, operating costs such as for crews, maintenance and insurance are typically paid by the owner of the vessel. Revenue from time chartering of vessels amounted to $ 45,679 45,450 91,328 88,979 Revenue from voyage contracts The Company’s revenues earned under voyage contracts (revenues for the transportation of cargo) were previously recognized ratably over the estimated relative transit time of each voyage. A voyage was deemed to commence when a vessel was available for loading and was deemed to end upon the completion of the discharge of the current cargo. Estimated losses on voyages are provided for in full at the time such losses become evident. Under a voyage charter, a vessel is provided for the transportation of specific goods between specific ports in return for payment of an agreed upon freight per ton of cargo. Upon adoption of ASC 606, the Company recognizes revenue ratably from port of loading to when the charterer’s cargo is discharged as well as defer costs that meet the definition of “costs to fulfill a contract” and relate directly to the contract. During 2017, no freight voyage existed and therefore, there was no impact on the Company’s retained earnings as at January 1, 2018. Revenue from voyage contracts amounted to $ 306 3,808 Pooling arrangements 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 points 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 as variable rate operating leases 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. The allocation of such net revenue may be subject to future adjustments by the pool however, such changes are not expected to be material. The Company recognizes net pool revenue on a monthly and quarterly basis, when the vessel has participated in a pool during the period and the amount of pool revenue can be estimated reliably based on the pool report. Revenue from vessels operating in pooling arrangements amounted to $ 1,405 1,776 Revenue from profit-sharing Profit-sharing revenues are calculated at an agreed percentage of the excess of the charterer’s average daily income (calculated on a quarterly or half-yearly basis) over an agreed amount and accounted for on an accrual basis based on provisional amounts and for those contracts that provisional accruals cannot be made due to the nature of the profit sharing elements, these are accounted for on the actual cash settlement or when such revenue becomes determinable. Profit sharing revenue amounted to $ 0 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 or freight rate. Since address commissions represent a discount (sales incentive) on services rendered by the Company and no identifiable benefit is received in exchange for the consideration provided to the charterer, these commissions are presented as a reduction of revenue.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In March 2020, the FASB issued ASU 2020-4, “Reference Rate Reform (Topic 848)” (“ASU 2020-4”), which provides optional guidance intended to ease the potential burden in accounting for the expected discontinuation of LIBOR as a reference rate in the financial markets. The guidance can be applied to modifications made to certain contracts to replace LIBOR with a new reference rate. The guidance, if elected, will permit entities to treat such modifications as the continuation of the original contract, without any required accounting reassessments or remeasurements. The ASU 2020-4 was effective for the Company beginning on March 12, 2020 and the Company will apply the amendments prospectively through December 31, 2022. There was no impact to the Company’s unaudited condensed consolidation financial statements as a result of adopting this standard update. Currently, the Company has various contracts that reference LIBOR and is assessing how this standard may be applied to specific contract modifications. In October 2018, the Financial Accounting Standards Board (“FASB”) issued ASU 2018-17, Consolidation (Topic 810): “Targeted Improvements to Related Party Guidance for Variable Interest Entities” (“ASU 2018-17”). ASU 2018-17 provides that indirect interests held through related parties in common control arrangements should be considered on a proportional basis for determining whether fees paid to decision makers and service providers are variable interests. This is consistent with how indirect interests held through related parties under common control are considered for determining whether a reporting entity must consolidate a VIE. For public business entities the amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The adoption of this new accounting guidance did not have a material effect on the Company’s consolidated financial statements. In August 2018, FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement”. This update modifies the disclosure requirements on fair value measurements. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, and earlier adoption is permitted. The adoption of this new accounting guidance did not have a material effect on the Company’s consolidated financial statements. In June 2016, FASB issued ASU No. 2016-13, “Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”. This standard requires entities to measure all expected credit losses of financial assets held at a reporting date based on historical experience, current conditions, and reasonable and supportable forecasts in order to record credit losses in a more timely manner. ASU 2016-13 also amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The standard is effective for interim and annual reporting periods beginning after December 15, 2019, although early adoption is permitted for interim and annual periods beginning after December 15, 2018. In November 2018, FASB issued ASU 2018-19 “Codification Improvements to topic 326, Financial Instruments-Credit Losses”. The amendments in this update clarify that operating lease receivables are not within the scope of ASC 326-20 and should instead be accounted for under the new leasing standard, ASC 842. In April 2019, FASB issued ASU 2019-04 “Codification Improvements to topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments”. In May 2019, FASB issued ASU 2019-05, “Financial Instruments-Credit Losses (Topic 326): Targeted Transition Relief”. The amendments in this update provide entities that have certain instruments within the scope of Subtopic 326-20, Financial Instruments-Credit Losses-Measured at Amortized Cost, with an option to irrevocably elect the fair value option in Subtopic 825-10, Financial Instruments-Overall, applied on an instrument-by-instrument basis for eligible instruments, upon adoption of Topic 326. The fair value option election does not apply to held-to-maturity debt securities. An entity that elects the fair value option should subsequently apply the guidance in Subtopics 820-10, Fair Value Measurement-Overall, and 825-10. In November 2019, FASB issued ASU No. 2019-11, Codification Improvements to Topic 326, Financial Instruments-Credit Losses. This update introduced an expected credit loss model for the impairment of financial assets measured at amortized cost basis. That model replaces the probable, incurred loss model for those assets. The standard is effective for interim and annual reporting periods beginning after December 15, 2019. The Company has assessed all the expected credit losses of its financial assets and the adoption of this ASU did not have a material impact on the Company’s consolidated financial statements.
