In connection with the IPO on May 12, 2014, the Partnership acquired from GasLog 100% of the ownership interests in GAS-three Ltd., GAS-four Ltd. and GAS-five Ltd., the entities that own the GasLog Shanghai , the GasLog Santiago and the GasLog Sydney (the “Initial Fleet”). On September 29, 2014, GasLog Partners acquired 100% of the ownership interests in GAS-sixteen Ltd. and GAS-seventeen Ltd., the entities that own two 145,000 cubic meters (“cbm”) LNG carriers, the Methane Rita Andrea and the Methane Jane Elizabeth , respectively, for an aggregate purchase price of $328,000. On July 1, 2015, GasLog Partners acquired 100% of the ownership interests in GAS-nineteen Ltd., GAS-twenty Ltd. and GAS-twenty one Ltd., the entities that own three 145,000 cbm LNG carriers, the Methane Alison Victoria , the Methane Shirley Elisabeth and the Methane Heather Sally , respectively, for an aggregate purchase price of $483,000. On November 1, 2016, GasLog Partners acquired 100% of the ownership interests in GAS-seven Ltd., the entity that owns a 155,000 cbm LNG carrier, the GasLog Seattle , for an aggregate purchase price of $189,000. On May 3, 2017, GasLog Partners acquired 100% of the ownership interests in GAS-eleven Ltd., the entity that owns a 174,000 cbm LNG carrier, the GasLog Greece , for an aggregate purchase price of $219,000. On July 3, 2017, GasLog Partners acquired 100% of the ownership interests in GAS-thirteen Ltd., the entity that owns a 174,000 cbm LNG carrier, the GasLog Geneva , for an aggregate purchase price of $211,000. On October 20, 2017, GasLog Partners acquired 100% of the ownership interests in GAS-eight Ltd., the entity that owns a 155,000 cbm LNG carrier, the Solaris , for an aggregate purchase price of $185,900. On April 26, 2018, GasLog Partners acquired 100% of the ownership interests in GAS-fourteen Ltd., the entity that owns a 174,000 cbm LNG carrier, the GasLog Gibraltar , for an aggregate purchase price of $207,000. On November 14, 2018, GasLog Partners acquired 100% of the ownership interests in GAS-twenty seven Ltd., the entity that owns a 170,000 cbm LNG carrier, the Methane Becki Anne , for an aggregate purchase price of $207,400. On April 1, 2019, GasLog Partners acquired 100% of the ownership interests in GAS-twelve Ltd., the entity that owns a 174,000 cbm LNG carrier, the GasLog Glasgow , for an aggregate purchase price of $214,000. The above acquisitions were accounted for as reorganizations of companies under common control. The Partnership’s historical results and net assets were retroactively restated to reflect the historical results of the acquired entities from their respective dates of incorporation by GasLog. The carrying amounts of assets and liabilities included are based on the historical carrying amounts of such assets and liabilities recognized by the subsidiaries. As of December 31, 2019, GasLog holds a 35.5% ownership interest in the Partnership (including 2.0% through its general partner interest). As a result of its 100% ownership of the general partner, and the fact that the general partner elects the majority of the Partnership’s directors in accordance with the Partnership Agreement, GasLog has the ability to control the Partnership’s affairs and policies. The Partnership’s principal business is the acquisition and operation of vessels in the LNG market, providing transportation services of LNG on a worldwide basis primarily under multi-year charters. GasLog LNG Services Ltd. (“GasLog LNG Services” or the “Manager”), a related party and a wholly owned subsidiary of GasLog, incorporated under the laws of the Bermuda, provides technical services to the Partnership. On May 18, 2018, the Partnership through the GasLog Shanghai entered the Cool Pool, an LNG carrier pooling arrangement operated by GasLog and Golar LNG Ltd. (the “Cool Pool”) to market their vessels operating in the LNG shipping spot market. The Cool Pool allowed the participating owners to optimize the operation of the pool vessels through improved scheduling ability, cost efficiencies and common marketing. The objective of the Cool Pool was to serve the growing LNG market by providing customers with reliable, flexible and innovative solutions to meet their increasingly complex shipping requirements. The Cool Pool chartered vessels (tri-fuel diesel electric (“TFDE”) LNG carriers in the 155,000-170,000 cbm range) for periods up to one year in duration as agents for the owners, who each remained responsible for the technical and commercial operation of their vessels and performance of the contracts. The Partnership through the GasLog Shanghai exited the Cool Pool on June 23, 2019. As of December 31, 2019, the companies listed below were 100% held by the Partnership: Cargo Place of Date of Capacity Name incorporation incorporation Principal activities Vessel (cbm) Delivery Date GAS-three Ltd.

Significant Accounting Policies	2. Significant Accounting Policies Statement of compliance The consolidated financial statements of the Partnership have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (the “IASB”). Basis of preparation The consolidated financial statements have been prepared on the historical cost basis. Historical cost is generally based on the fair value of the consideration given in exchange for assets. The principal accounting policies are set out below. The consolidated financial statements are expressed in U.S. dollars (“USD”), which is the functional currency of the Partnership and each of its subsidiaries because their vessels operate in international shipping markets, in which revenues and expenses are primarily settled in USD and the Partnership’s most significant assets and liabilities are paid for and settled in USD. In considering going concern, management has reviewed the Partnership’s future cash requirements, covenant compliance and earnings projections. As of December 31, 2019, the Partnership’s current assets totaled $109,353 while current liabilities totaled $186,743, resulting in a negative working capital position of $77,390. Management anticipates that the Partnership’s primary sources of funds will be available cash, cash from operations, borrowings under existing debt and future debt and equity financings, if any. Management believes that these sources of funds will be sufficient for the Partnership to meet its liquidity needs and comply with its banking covenants for at least twelve months from the end of the reporting period and therefore it is appropriate to prepare the financial statements on a going concern basis, although there can be no assurance that the Partnership will be able to obtain future debt and equity financing on terms acceptable to the Partnership. On March 3, 2020, the Partnership’s board of directors authorized the consolidated financial statements for issuance and filing. Basis of consolidation The accompanying consolidated financial statements include the accounts of the Partnership and its subsidiaries assuming that they are consolidated from the date of their incorporation by GasLog, as they were under the common control of GasLog. All intra-group transactions and balances are eliminated on consolidation. Accounting for (i) revenues and related operating expenses and (ii) voyage expenses and commissions Revenues comprise revenues from time charters for the charter hire of the Partnership’s vessels earned during the period in accordance with existing contracts and gross pool revenues. A time charter represents a contract entered into for the use of a vessel for a specific period of time and a specified daily charter hire rate. Time charter revenue is recognized as earned on a straight-line basis over the term of the relevant time charter starting from the vessel’s delivery to the charterer, except for any off-hire period, when a charter agreement exists, the vessel is made available and services are provided to the charterer and collection of the related revenue is reasonably assured. Unearned revenue includes cash received prior to the reporting date relating to services to be rendered after the reporting date. Accrued revenue represents income recognized in advance as a result of the straight-line revenue recognition in respect of charter agreements that provide for varying charter rates. Under a time charter arrangement, the hire rate per the charter agreement has two components: the lease component and the service component relating to the vessel operating costs. The revenue in relation to the lease component of the agreements is accounted for under IFRS 16 Leases . The revenue in relation to the service component relates to vessel operating expenses, which include expenses that are paid by the vessel owner such as management fees, crew wages, provisions and stores, technical maintenance and insurance expenses. These costs are essential to operating a charter and the charterers receive the benefit of these when the vessel is used during the contracted time and, therefore, these costs are accounted for in accordance with the requirements of IFRS 15 Revenue from Contracts with Customers . Pool revenues are recognized on a gross basis representing time charter revenues earned by a GasLog Partners vessel participating in the pool under charter agreements where GasLog Partners contracts directly with charterers. Revenue is recognized on a monthly basis, when the vessel is made available and services are provided to the charterer during the period, the amount can be estimated reliably and collection of the related revenue is reasonably assured. Time charter hires are received monthly in advance and are classified as liabilities until such time as the criteria for recognizing the revenue as earned are met. Under a time charter arrangement the vessel operating expenses such as management fees, crew wages, provisions and stores, technical maintenance and insurance expenses, as well as broker’s commissions, are paid by the vessel owner, whereas the majority of voyage expenses such as bunkers, port expenses, agents’ fees and extra war risk insurance are paid by the charterer. Management believes that mobilization of a vessel from a previous port of discharge to a subsequent port of loading does not result in a separate benefit for charterers and that the activity is thus incapable of being distinct. This activity is considered to be a required set-up activity to fulfill the contract. Consequently, positioning and repositioning fees and associated expenses should be recognized over the period of the contract, and not at a certain point in time following the adoption of IFRS 15 Revenue from Contracts with Customers . Consequently, positioning fees, repositioning fees and associated voyage expenses are recognized over the period of each contract, to match the recognition of the respective hire revenues realized. All other voyage expenses and vessel operating costs are expensed as incurred, with the exception of commissions, which are also recognized on a pro-rata basis over the duration of the period of the time charter. Bunkers’ consumption included in voyage expenses represents mainly bunkers consumed during vessels’ unemployment and off-hire. Net pool allocation The Partnership because of its participation in the Cool Pool (until June 23, 2019) also received a net allocation from the pool, which was recognized separately in the consolidated statement of profit or loss under “Net Pool Allocation” and represented GasLog Partners’ share of the net revenues earned from the other pool participants’ vessels less the other participants’ share of the net revenues earned by GasLog Partners’ vessels included in the pool. Each participant’s share of the net pool revenues was based on the number of pool points attributable to its vessels and the number of days such vessels participated in the pool. Financial income and costs Interest income, interest expense, other borrowing costs and realized loss on derivatives are recognized on an accrual basis. Foreign currencies Transactions in currencies other than USD are recognized at the rates of exchange prevailing at the dates of the transactions. At the end of each reporting period, monetary assets and liabilities denominated in other currencies are retranslated into USD at the rates prevailing at that date. All resulting exchange differences are recognized in the consolidated statement of profit or loss in the period in which they arise. Deferred financing costs Commitment, arrangement, structuring, legal and agency fees incurred for obtaining new loans or refinancing existing facilities are recorded as deferred loan issuance costs and classified contra debt while the fees incurred for the undrawn facilities are classified under non-current assets in the statement of financial position and are classified contra debt on the drawdown dates. Deferred financing costs are deferred and amortized to financial costs over the term of the relevant loan, using the effective interest method. When the relevant loan is terminated or extinguished, the unamortized loan fees are written-off in the consolidated statement of profit or loss. Vessels Vessels are stated at cost less accumulated depreciation and any accumulated impairment loss. The initial cost of an asset comprises its purchase price and any directly attributable costs of bringing the asset to its working condition. The cost of an LNG vessel is split into two components, a “vessel component” and a “dry-docking component”. Depreciation for the vessel component is calculated on a straight-line basis, after taking into account the estimated residual values, over the estimated useful life of this major component of the value of the vessels. Residual values are based on management’s estimation of the amount that the Partnership would currently obtain from disposal of its vessels, after deducting the estimated costs of disposal, if the vessels were already of the age and in the condition expected at the end of their useful life. The LNG vessels are required to undergo a dry-docking overhaul every five years that cannot be performed while the vessels are operating to restore their service potential and to meet their classification requirements. The dry-docking component is estimated at the time of a vessel’s delivery from the shipyard or acquisition from the previous owner and is measured based on the estimated cost of the first dry-docking, subsequent to its acquisition, based on the Partnership’s historical experience with similar types of vessels. For subsequent dry-dockings, actual costs are capitalized when incurred. The dry-docking component is depreciated over the period of five years in the case of new vessels, and until the next dry-docking for secondhand vessels (which is performed within five years from the vessel’s last dry-docking). Costs that will be capitalized as part of the future dry-dockings will include a variety of costs incurred directly attributable to the dry-dock, and costs incurred to meet classification and regulatory requirements, as well as expenses related to the dock preparation and port expenses at the dry-dock shipyard, general shipyard expenses, expenses related to hull, external surfaces and decks, expenses related to machinery and engines of the vessel, as well as expenses related to the testing and correction of findings related to safety equipment on board. Dry-docking costs do not include vessel operating expenses such as replacement parts, crew expenses, provisions, lubricants consumption, insurance, management fees or management costs during the dry-docking period. Expenses related to regular maintenance and repairs of the vessels are expensed as incurred, even if such maintenance and repair occurs during the same time period as the dry-docking. The expected useful lives are as follows: Vessel LNG vessel component 35 years Dry-docking component 5 years Management estimates the useful life of its vessels to be 35 years from the date of initial delivery from the shipyard. Secondhand vessels are depreciated from the date of their acquisition through their remaining estimated useful life. The useful lives and the depreciation method are reviewed annually to ensure that the method and period of depreciation are consistent with the expected pattern of economic benefits from Partnership’s vessels. The residual value is also reviewed at each financial period end. If expectations differ from previous estimates, the changes are accounted for prospectively in profit or loss in the period of the change and future periods. Management estimates residual value of its vessels to be equal to the product of its lightweight tonnage (“LWT”) and an estimated scrap rate per LWT. Effective December 31, 2019, following management’s annual reassessment, the estimated scrap rate per LWT was decreased. This change in estimate is expected to increase the future annual depreciation by $352. The estimated residual value of the vessels may not represent the fair market value at any time partly because market prices of scrap values tend to fluctuate. The Partnership might revise the estimate of the residual values of the vessels in the future in response to changing market conditions. Ordinary maintenance and repairs that do not extend the useful life of the asset are expensed as incurred. When vessels are sold, they are derecognized and any gain or loss resulting from their disposals is included in profit or loss. Impairment of vessels All vessels are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Whenever the carrying amount of a vessel exceeds its recoverable amount, an impairment loss is recognized in the consolidated statement of profit or loss. The recoverable amount is the higher of a vessel’s fair value less cost of disposal and “value in use”. The fair value less cost of disposal is the amount obtainable from the sale of a vessel in an arm’s length transaction less the costs of disposal, while “value in use” is the present value of estimated future cash flows expected to arise from the continuing use of a vessel and from its disposal at the end of its useful life. Recoverable amounts are estimated for individual vessels. Each vessel is considered to be a single cash-generating unit. The fair value less cost of disposal of the vessels is estimated from market-based evidence by appraisal that is normally undertaken by professionally qualified brokers. Reimbursable capital expenditures Costs eligible for capitalization that are contractually reimbursable by our charterers are recognized on a gross basis in the period incurred under “Vessels”. Concurrently, an equal amount is deferred as a liability and amortized to profit or loss as income over the remaining tenure of the charter party agreement. Leases Until December 31, 2018, the Partnership’s leases of vessel communication equipment were classified as operating leases. Payments made under operating leases (net of any incentives received from the lessor) were charged to profit or loss on a straight-line basis over the period of the lease. From January 1, 2019 and onwards, each lease has been recognized as a right-of-use asset, with a corresponding liability recognized at the date at which the leased asset is available for use by the Partnership. Assets and liabilities arising from a lease are initially measured on a present value basis, i.e. at the present value of the minimum lease payments, discounted at the interest rate implicit in the lease, if practicable, or else at the Group’s incremental borrowing rate. The corresponding rental obligations, net of future finance charges, are included in current and non-current liabilities as lease liabilities. Each lease payment is allocated between the liability and finance cost. The finance cost is charged to profit or loss over the lease period so as to produce a constant periodic rate of interest on the remaining balance of the liability for each period. The lease liability is subsequently measured by increasing the carrying amount to reflect interest on the lease liability (using the effective interest rate method) and by reducing the carrying amount to reflect lease payments made. The right-of-use asset is depreciated over its useful life or over the shorter of its useful life and the lease term if there is no reasonable certainty that the Partnership will obtain ownership at the end of the lease term. Payments associated with short-term leases and low-value assets are recognized on a straight-line basis as an expense in profit or loss. Short-term leases are leases with a lease term of 12 months or less. Low-value items comprise of low value vessel or office equipment. Provisions Provisions are recognized when the Partnership has a present obligation (legal or constructive) as a result of a past event, it is probable that the Partnership will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. The amount recognized as a provision is the best estimate of the consideration required to settle the present obligation at the end of the reporting period, taking into account the risks and uncertainties surrounding the obligation. Where a provision is measured using the cash flows estimated to settle the present obligation, its carrying amount is the present value of those cash flows. When some or all of the economic benefits required to settle a provision are expected to be recovered from a third party, a receivable is recognized as an asset if it is virtually certain that reimbursement will be received and the amount of the receivable can be measured reliably. Inventories Inventories represent lubricants on board the vessel and, in the event of a vessel not being employed under a charter, bunkers on board the vessel. Inventories are stated at the lower of cost calculated on a first-in, first-out basis, and net realizable value. Financial instruments Financial assets and liabilities are recognized when the Partnership has become a party to the contractual provisions of the instrument. All financial instruments are initially recognized at fair value. Transaction costs that are directly attributable to the acquisition or issue of financial assets and financial liabilities (other than financial assets and financial liabilities at fair value through profit or loss) are added to or deducted from the fair value of the financial assets or financial liabilities, as appropriate, on initial recognition. · Cash and cash equivalents Cash represents cash on hand and deposits with banks which are repayable on demand. Cash equivalents represent short-term, highly liquid investments which are readily convertible into known amounts of cash with original maturities of three months or less at the time of purchase that are subject to an insignificant risk of change in value. · Short-term investments Short-term investments represent short-term, highly liquid time deposits placed with financial institutions which are readily convertible into known amounts of cash with original maturities of more than three months but less than 12 months at the time of purchase that are subject to an insignificant risk of change in value. · Trade receivables Trade receivables are carried at the amount expected to be received from the third party to settle the obligation. At each reporting date, all potentially uncollectible accounts are assessed individually for purposes of determining the appropriate allowance for doubtful accounts. Trade receivables are recognized initially at their transaction price and subsequently measured at amortized cost using the effective interest method. Trade receivables are written off when there is no reasonable expectation of recovery. See Note 5 for further information about the Partnership’s accounting for trade receivables. The simplified approach is applied to trade and other receivables and the Partnership recognizes lifetime expected credit losses (“ECLs”) on the trade receivables. Under the simplified approach, the loss allowance is always equal to ECLs. · Borrowings Borrowings are measured at amortized cost, using the effective interest method. Any difference between the proceeds (net of transaction costs) and the settlement of the borrowings is recognized in the statement of profit or loss over the term of the borrowings. · Derivative financial instruments Derivative financial instruments, such as interest rate swaps or forward foreign exchange contracts, are used to economically hedge the Partnership’s exposure to interest rate or foreign exchange rate risks. Derivative financial instruments are initially recognized at fair value and are subsequently remeasured to their fair value at each reporting date. The resulting changes in fair value are recognized in profit or loss immediately, unless the derivative is designated and effective as a hedging instrument, in which case the timing of the recognition in profit or loss depends on the nature of the hedge relationship. Derivatives are presented as assets when their valuation is favorable to the Partnership and as liabilities when unfavorable to the Partnership. Criteria for classifying a derivative instrument in a hedging relationship include: (1) the hedging instrument is expected to be highly effective in achieving offsetting changes in fair value or cash flows attributable to the hedged risk; (2) the effectiveness of the hedge can be reliably measured; (3) there is adequate documentation of the hedging relationships at the inception of the hedge; and (4) for cash flow hedges, the forecasted transaction that is the hedged item in the hedging relationship must be considered highly probable. The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in other comprehensive income. The gain or loss relating to the ineffective portion is recognized immediately in the consolidated statement of profit or loss. Amounts previously recognized in other comprehensive income and accumulated in equity are reclassified to the consolidated statement of profit or loss in the periods when the hedged item affects the consolidated statement of profit or loss. Hedge accounting is discontinued when the Partnership terminates the hedging relationship, when the hedging instrument expires or is sold, terminated or exercised, or when it no longer qualifies for hedge accounting. Any gain or loss accumulated in equity at that time remains in equity and is recognized in the consolidated statement of profit or loss when the hedged item affects the consolidated statement of profit or loss. When a forecast transaction designated as the hedged item in a cash flow hedge is no longer expected to occur, the gain or loss accumulated in equity is recycled immediately to the consolidated statement of profit or loss. Segment information Each vessel-owning company owns one LNG carrier which is operated under a time charter with similar operating and economic characteristics. Consequently, the information provided to the Chief Executive Officer (the Partnership’s chief operating decision maker) to review the Partnership’s operating results and allocate resources is on a consolidated basis for a single reportable segment. Furthermore, when the Partnership charters a vessel to a charterer, the charterer is free to trade the vessel worldwide and, as a result, the disclosure of geographic information is impracticable. Share-based compensation Share-based compensation to executives and others providing similar services is measured at the fair value of the equity instruments on the grant date. Details regarding the determination of the fair value of share-based transactions are set out in Note 21. The fair value determined at the grant date of the equity-settled share-based compensation is expensed on a straight-line basis over the vesting period, based on the Partnership’s estimate of equity instruments that will eventually vest, with a corresponding increase in equity. At the end of each reporting period, the Partnership revises its estimate of the number of equity instruments expected to vest. The impact of the revision of the original estimates, if any, is recognized in the consolidated statement of profit or loss such that the cumulative expense reflects the revised estimate, with a corresponding adjustment to the share-based compensation reserve. Critical accounting judgments and key sources of estimation uncertainty The preparation of the consolidated financial statements in conformity with IFRS requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses recognized in the consolidated financial statements. The Partnership’s management evaluates whether estimates should be made on an ongoing basis, utilizing historical experience, consultation with experts and other methods which management considers reasonable in the particular circumstances. However, uncertainty about these assumptions and estimates could result in outcomes that could require a material adjustment to the carrying amount of the asset or liability in the future. Critical accounting judgments are those that reflect significant judgments of uncertainties and potentially result in materially different results under different assumptions and conditions. Critical accounting judgments In the process of applying the Partnership’s accounting policies, management has made the following judgments, apart from those involving estimations, that had the most significant effect on the amounts recognized in the consolidated financial statements. Classification of the Partnership interests: The interests in the Partnership comprise common units, preference units, a general partner interest and incentive distribution rights. Under the terms of the Partnership Agreement, the Partnership is required to distribute 100% of available cash (as defined in the Partnership Agreement) with respect to each quarter within 45 days of the end of the quarter to the partners. Available cash can be summarized as cash and cash equivalents less an amount equal to cash reserves established by the board of directors to (i) provide for the proper conduct of the business of the Partnership group (including reserves for future capital expenditures and for anticipated future credit needs of the Partnership group) subsequent to such quarter, (ii) comply with applicable law or any loan agreement, security agreement, mortgage, debt instrument or other agreement or obligation to which any Partnership group member is a party or by which it is bound or its assets are subject and/or (iii) provide funds for certain distributions relating to future periods. In reaching a judgment as to whether the interests in the Partnership should be classified as liabilities or equity interests, the Partnership has considered the wide discretion of the board of directors to determine whether any portion of the amount of cash available to the Partnership constitutes available cash and that it is possible that there could be no available cash. In the event that there is no available cash, as determined by the board of directors, the Partnership does not have a contractual obligation to make a distribution. Accordingly, management has concluded that the Partnership interests do not represent a contractual obligation on the Partnership to deliver cash and therefore should be classified as equity within the financial statements. Key sources of estimation uncertainty are as follows: Impairment of vessels: The Partnership evaluates the carrying amounts of each of its vessels to determine whether there is any indication that those vessels have suffered an impairment loss by considering both internal and external sources of information. If any such indication exists, the recoverable amount of vessels is estimated in order to determine the extent of the impairment loss, if any. The total carrying amount of the Partnership’s vessels as of December 31, 2019, was $2,286,430 (December 31, 2018: $2,509,283). Recoverable amount is the higher of fair value less costs to sell and value in use. The Partnership’s estimates of recoverable value assume that the vessels are all in seaworthy condition without need for repair and certified in class without notations of any kind. In assessing the fair value less cost to sell of the vessel, the Partnership obtains charter-free market values for its vessels from independent and internationally recognized ship brokers on a semi-annual basis, which are also commonly used and accepted by the Partnership’s lenders for determining compliance with the relevant covenants in the Partnership’s credit facilities. Vessel values can be highly volatile, so the charter-free market values may not be indicative of the future market value of the Partnership’s vessels, or prices that could be achieved if it were to sell them. In assessing value in use, the estimated future cash flows are discounted to their present value using a discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the estimates of future cash flows have not been adjusted. The projection of cash flows related to vessels is complex and requires management to make various estimates including future charter rates, vessel operating expenses and the discount rate. As of December 31, 2019, the carrying amounts of each of the five steam turbine propulsion (“Steam”) vessels (the Methane Rita Andrea , the Methane Jane Elizabeth , the Methane Alison Victoria , the Methane Shirley Elisabeth and the Methane Heather Sally ) and three TFDE vessels (the GasLog Seattle , the Solaris and the Methane Becki Anne ) were higher than the charter-free market values estimated by ship brokers. The Partnership concluded that this, together with certain other events and circumstances (as further described in Note 3), indicated the existence of potential impairment of these vessels. As a result, the Partnership performed an impairment assessment for these vessels by comparing their values in use, being the discounted projected net operating cash flows for these vessels to their carrying values. The Partnership’s strategy is to charter its vessels on term contracts, providing the Partnership with contracted stable cash flows. The assumptions that the Partnership used in its discounted projected net operating cash flow analysis included, among others, utilization, operating revenues, voyage expenses and commissions, dry-docking costs, operating expenses (including vessel management costs), residual values and the discount rate. The key assumptions, being those to which the outcome of the impairment assessment is most sensitive, are the estimate of charter rates for non-contracted revenue days and the discount rate. Revenue assumptions were based on contracted time charter rates up to the end of the current contract for each vessel, as well as the estimated average time charter rates for the remaining life of the vessel after the completion of its current contract. The revenue assumptions exclude days of scheduled off-hire based on the fleet’s historical performance and internal forecasts. The estimated daily time charter rates used for non-contracted revenue days after the completion of the current time charter are based on a combination of (i) recent charter market rates, (ii) conditions existing in the LNG market as of December 31, 2019, (iii) historical average time charter rates, based on publications by independent third party maritime research services (“maritime research publications”), (iv) estimated future time charter rates, based on maritime research publications that provide such forecasts and (v) management’s internal assessment of long-term charter rates achievable by each class of vessel. More specifically, for vessels whose charters will expire within 2020, the estimated charter rates and utilization for the first year from the reporting date were based on the approved annual budget for the year, which was formed based on the anticipated market conditions for 2020 and the latest available maritime research publications from ship brokers for short-term (less than 12 months) employment of a vessel operating in the spot market on less than one-year time charter contracts. For non-contracted periods starting on January 1, 2021 for already expired charters or upon the expiration of the firm charter period of a vessel within 2021 and up to December 31, 2024, the Partnership used the most recent charter market rate for a 5-year time charter rate based on available data from maritime research publications, which is $45 per day for the Steam vessels and $65 per day for the TFDE vessels. Such rates are lower than prevailing spot rates as of December 31, 2019. For the remaining period from January 1, 2025, through the end of each vessel’s useful life (for non-contracted periods), the estimated average time charter rates for Steam and TFDE vessels were based on analysis of future supply and demand for LNG, analysis of future LNG shipping supply and demand balances, internally estimated and market-derived costs of building and financing newbuild LNG vessels, the technical characteristics of each vessel and an assessment of the appropriate discount for Steam and TFDE vessels’ charter rates compared to modern newbui

In April and May 2017, GasLog LNG Services entered into agreements in relation to investments in certain of the Partnership’s and GasLog’s vessels, with the aim of enhancing their operational performance. On March 7, 2019, GasLog LNG Services and one of its suppliers signed an interim agreement regarding the reimbursement of amounts already paid by the Partnership in respect of the aforementioned enhancements, which were not timely delivered or in the correct contractual condition. In accordance with the terms of this agreement, $7,465 was reimbursed to the Partnership, with realized foreign exchange losses of $542 recognized in profit or loss. On April 26, 2018, the Partnership acquired from GasLog 100% of the ownership interests in GAS-fourteen Ltd., the entity which owns the GasLog Gibraltar , for an aggregate purchase price of $207,000. As consideration for this acquisition, the Partnership paid GasLog $19,085 representing the difference between the $207,000 aggregate purchase price, $143,622 of outstanding indebtedness of the acquired entity assumed by the Partnership and $45,000 of new privately placed common units issued to GasLog (1,858,975 common units at a price of $24.21 per unit) plus an adjustment of $707 in order to maintain the agreed working capital position in the acquired entity of $1,000 at the time of acquisition. On November 14, 2018, the Partnership acquired from GasLog 100% of the ownership interests in GAS-twenty seven Ltd., the entity which owns the Methane Becki Anne , for an aggregate purchase price of $207,400. As consideration for this acquisition, the Partnership paid GasLog $109,398 representing the difference between the $207,400 aggregate purchase price and the $93,896 of outstanding indebtedness of the acquired entity assumed by the Partnership less an adjustment of $4,106 in order to maintain the agreed working capital position in the acquired entity of $1,000 at the time of acquisition. On April 1, 2019, the Partnership acquired from GasLog 100% of the ownership interests in GAS-twelve Ltd., the entity which owns the GasLog Glasgow , for an aggregate purchase price of $214,000. As consideration for this acquisition, the Partnership paid GasLog $93,646 representing the difference between the $214,000 aggregate purchase price and the $134,107 of outstanding indebtedness of the acquired entity assumed by the Partnership plus an adjustment of $13,753 in order to maintain the agreed working capital position in the acquired entity of $1,000 at the time of acquisition. As of December 31, 2019, a number of increasingly strong negative indicators, such as the difference between ship broker estimates of the fair market values and the carrying values of the Partnership’s Steam vessels, the lack of liquidity in the market for term employment for Steam vessels and reduced expectations for the estimated rates at which such term employment could be secured, together with the continued addition of modern, larger and more fuel efficient LNG carriers to the global fleet, prompted the Partnership to perform an impairment assessment of its vessels in accordance with the Partnership’s accounting policy (Note 2). The recoverable amounts (values in use) for the five Steam vessels owned by the Partnership, i.e. the Methane Rita Andrea , the Methane Jane Elizabeth , the Methane Alison Victoria , the Methane Shirley Elisabeth and the Methane Heather Sally calculated as per above were lower than the respective carrying amounts of these vessels and, consequently, an aggregate impairment loss of $138,848 was recognized in profit or loss in the year ended December 31, 2019, as illustrated below: As of and for the year ended December 31, 2019 Initial carrying Impairment loss Net book value Vessel amount on vessels (recoverable amount) Methane Rita Andrea 126,330 (27,300) 99,030 Methane Jane Elizabeth 131,554 (29,476) 102,078 Methane Alison Victoria 128,229 (31,625) 96,604 Methane Shirley Elisabeth 130,141 (26,709) 103,432 Methane Heather Sally 129,654 (23,738) 105,916 Total 645,908 (138,848) 507,060 The most sensitive and/or subjective assumptions that have the potential to affect the outcome of the impairment assessment for the Steam vessels are the projected charter hire rate used to forecast future cash flows for non-contracted revenue days (the “re-chartering rate”) and the discount rate used. The average re-chartering rate over the remaining useful life of the vessels used in our impairment exercise for the Steam vessels was $41 per day (December 31, 2018: $58 per day). Increasing/decreasing the average re-chartering rate used by $5 per day would result in an aggregate decrease/increase in the impairment charge of $92,742. The discount rate used for the Steam vessels was 7.25% as of December 31, 2019 (December 31, 2018: 7.00%). Increasing/decreasing the discount rate by 0.5% would increase/(decrease) the impairment loss by $18,326/($19,556), respectively.

On May 16, 2017, GasLog Partners commenced an “at-the-market” common equity offering programme (“ATM Programme”) under which the Partnership may, from time to time, raise equity through the issuance and sale of new common units having an aggregate offering price of up to $100,000 in accordance with the terms of an equity distribution agreement, entered into on the same date. Citigroup Global Markets Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated, Credit Suisse Securities (USA) LLC and Morgan Stanley & Co. LLC have agreed to act as sales agents. On November 3, 2017, the Partnership entered into the Amended and Restated Equity Distribution Agreement to increase the size of the ATM Programme to $144,040 and include UBS Securities LLC as a sales agent.

Matters that require the approval of a “unit majority” require the approval of a majority of the outstanding common units voting as a single class. In voting their common units the general partner and its affiliates will have no fiduciary duty or obligation whatsoever to the Partnership or the limited partners, including any duty to act in good faith or in the best interests of the Partnership or the limited partners. Each outstanding common unit is entitled to one vote on matters subject to a vote of common unitholders. However, to preserve the Partnership’s ability to claim an exemption from U.S. federal income tax under Section 883 of the Code, if at any time any person or group owns beneficially more than 4.9% of any class or series of units then outstanding, any units beneficially owned by that person or group in excess of 4.9% may not be voted on any matter and will not be considered to be outstanding when sending notices of a meeting of limited partners, calculating required votes (except for purposes of nominating a person for election to the board of directors), determining the presence of a quorum or for other similar purposes under the Partnership Agreement, unless otherwise required by law. Effectively, this means that the voting rights of any such unitholders in excess of 4.9% will be redistributed pro rata among the other common unitholders holding less than 4.9% of the voting power of all classes of units entitled to vote. The general partner, its affiliates and persons who acquired common units with the prior approval of the board of directors will not be subject to this 4.9% limitation except with respect to voting their common units in the election of the elected directors. This loss of voting rights does not apply to the preference units. The Partnership holds a meeting of the limited partners every year to elect one or more members of the board of directors and to vote on any other matters that are properly brought before the meeting. The general partner retains the right to appoint four of the directors. Preference unitholders generally have no voting rights. However, the consent of at least two thirds of the outstanding preference units, voting as a single class, is required prior to any amendment to the Partnership Agreement that would have a material adverse effect on the existing terms of the preference units, the issuance of securities that rank pari passu to the preference units if distributions are in arrears, or the issuance of securities that rank senior to the preference units. In addition, preference unitholders become entitled to elect one director to the Partnership’s board of directors if and whenever distributions payable are in arrears for six or more quarterly periods, whether or not consecutive. In such a case, the general partner will also be entitled to appoint one additional director to the board of directors. General Partner Interest The Partnership Agreement provides that the general partner initially will be entitled to 2.0% of all distributions that the Partnership makes prior to its liquidation. The general partner has the right, but not the obligation, to contribute a proportionate amount of capital to the Partnership to maintain its 2.0% general partner interest if the Partnership issues additional units. The general partner’s 2.0% interest, and the percentage of the Partnership’s cash distributions to which it is entitled, will be proportionately reduced if the Partnership issues additional units in the future and the general partner does not contribute a proportionate amount of capital to the Partnership in order to maintain its 2.0% general partner interest. The general partner will be entitled to make a capital contribution in order to maintain its 2.0% general partner interest in the form of the contribution to the Partnership of common units based on the current market value of the contributed common units. Incentive Distribution Rights IDRs represented the right to receive an increasing percentage of quarterly distributions of available cash from operating surplus after the payment of preference unit distributions and after the minimum quarterly distribution and the target distribution levels had been achieved. Since completion of the IPO, GasLog had held 100% of the IDRs. The IDRs may be transferred separately from any other interests, subject to restrictions in the Partnership Agreement. Except for transfers of incentive distribution rights to an affiliate or another entity as part of a merger or consolidation with or into, or sale of substantially all of the assets to, such entity, the approval of a majority of the Partnership’s common units (excluding common units held by the general partner and its affiliates), voting separately as a class, is generally required for a transfer of the IDRs to a third party prior to March 31, 2019. Any transfer by GasLog of the IDRs would not change the percentage allocations of quarterly distributions with respect to such right. On November 27, 2018, the Partnership Agreement was amended to allow for the substitution of the then existing IDRs with a new class of IDRs (the “New IDRs”, together with the Old IDRs, the “IDRs”) with revised rights to distributions. Pursuant to this amendment, the 48.0% tier of distributions to the New IDRs holders was removed, while the definition of available cash from operating surplus for distribution to the New IDRs holders was revised to exclude any available cash from operating surplus generated from third-party (i.e., non-GasLog) acquisitions, as defined in the agreement. In exchange for the waiving of the aforementioned rights, the Partnership paid $25,000 to GasLog, the holder of the IDRs, sourced from available cash. The following table illustrates the percentage allocation of the additional available cash from operating surplus after the payment of preference unit distributions, in respect to such rights, until November 27, 2018: Marginal Percentage Interest in Distributions Total Quarterly Distribution General Holders of Old IDRs Target Amount Unitholders Partner IDRs Minimum Quarterly Distribution $ 0.375 98.0 % 2.0 % 0 % First Target Distribution $ 0.375 up to $ 0.43125 98.0 % 2.0 % 0 % Second Target Distribution $ 0.43125 up to $ 0.46875 85.0 % 2.0 % 13.0 % Third Target Distribution $ 0.46875 up to $ 0.5625 75.0 % 2.0 % 23.0 % Thereafter Above $ 0.5625 50.0 % 2.0 % 48.0 % Effective November 27, 2018 (and until the IDR elimination, described above), the percentage allocation of the additional available cash from operating surplus after the payment of preference unit distributions and excluding available cash from operating surplus derived from non-GasLog acquisitions, was amended, in respect to such rights, as follows: Marginal Percentage Interest in Distributions Total Quarterly Distribution General Holders of New IDRs Target Amount Unitholders Partner IDRs Minimum Quarterly Distribution $ 0.375 98.0 % 2.0 % 0 % First Target Distribution $ 0.375 up to $ 0.43125 98.0 % 2.0 % 0 % Second Target Distribution $ 0.43125 up to $ 0.46875 85.0 % 2.0 % 13.0 % Thereafter Above $ 0.46875 75.0 % 2.0 % 23.0 % Following the IDR elimination, 98% of the available cash is distributed to the common unitholders and 2% is distributed to the general partner. The updated earnings allocation applies to the Partnership’s earnings for the three months ended June 30, 2019 and onwards (Note 20). Subordinated Units Since the IPO and until May 16, 2017, GasLog held all of the Partnership’s subordinated units. The principal difference between the common units and subordinated units was that in any quarter during the subordination period the subordinated units were entitled to receive the minimum quarterly distribution of $0.375 per unit only after the common units had received the minimum quarterly distribution and arrearages in the payment of the minimum quarterly distribution from prior quarters. Subordinated units did not accrue arrearages. In accordance with the terms of the Partnership Agreement, the subordination period generally would end if the Partnership had earned and paid at least $0.375 on each outstanding common and subordinated unit and the corresponding distribution on the general partner’s 2.0% interest for any three consecutive four-quarter periods ending on or after March 31, 2017. On May 16, 2017, the subordination period expired and consequently all 9,822,358 subordinated units held by GasLog converted into common units on a one-for-one basis and now participate pro rata with all other outstanding common units in distributions of available cash. Class B units The Class B units have all of the rights and obligations attached to the common units, except for voting rights and participation in distributions until such time as GasLog exercises its right to convert the Class B units to common units. The Class B units will become eligible for conversion on a one-for-one basis into common units at GasLog’s option on July 1, 2020, July 1, 2021, July 1, 2022, July 1, 2023, July 1, 2024 and July 1, 2025 for the Class B-1 units, Class B-2 units, Class B-3 units, Class B-4 units, Class B-5 units and Class B-6 units, respectively. Preference Units From and including the original issue date to, but excluding, June 15, 2027, distributions on the Series A Preference Units will accrue at 8.625% per annum per $25.00 of liquidation preference per unit. From and including June 15, 2027, the distribution rate will be a floating rate equal to the three-month London Interbank Offered Rate (“LIBOR”)* plus a spread of 6.31% per annum per $25.00 of liquidation preference per unit of Series A Preference Units. From and including the original issue date to, but excluding, March 15, 2023, distributions on the Series B Preference Units will accrue at 8.200% per annum per $25.00 of liquidation preference per unit. From and including March 15, 2023, the distribution rate will be a floating rate equal to three-month LIBOR* plus a spread of 5.839% per annum per $25.00 of liquidation preference per unit of Series A Preference Units. From and including the original issue date to, but excluding, March 15, 2024, the distribution rate for the Series C Preference Units will accrue at 8.500% per annum per $25.00 of liquidation preference per unit. From and including March 15, 2024, the distribution rate will be a floating rate equal to the three-month LIBOR* plus a spread of 5.317% per annum per $25.00 of liquidation preference per unit of Series C Preference Units. The initial distribution on the Series C Preference Units is payable on March 15, 2019. The Preference Units issued are not convertible into common units and have been accounted for as equity instruments based on certain characteristics such as the absolute discretion held by our board of directors over distributions, which can be deferred and accumulated, as well as the redemption rights held only by the Partnership. The Series A, Series B and Series C Preference Units have preference upon liquidation and the holders would receive $25.00 per unit plus any accumulated and unpaid distributions. * Upon discontinuance of the LIBOR base rate, the appointed calculation agent will use a substitute or successor base rate that it has determined in its discretion, after consultation with the Partnership, and which is most comparable to the LIBOR base rate .

Loan From Related Parties: Following the IPO on May 12, 2014, the Partnership entered into a $30,000 revolving credit facility (the “Old Sponsor Credit Facility”) with GasLog to be used for general partnership purposes. The credit facility was unsecured and provided for an availability period of 36 months and bore interest at a rate of 5.0% per annum, with no commitment fee for the first year. After the first year, the interest increased to a rate of 6.0% per annum, with an annual 2.4% commitment fee on the undrawn balance. Each advance drawn was repayable within a period of 6 months after the respective drawdown date but was subject to unconditional right of immediate renewal if no repayment was made. On April 3, 2017, the Partnership signed a deed of termination with respect to the Old Sponsor Credit Facility with GasLog. On the same date, GasLog Partners entered into a new unsecured five-year term loan of $45,000 and a new five-year revolving credit facility of $30,000 with GasLog (together, the “New Sponsor Credit Facility”). On April 5, 2017, under the New Sponsor Credit Facility, an amount of $45,000 under the term loan facility and an amount of $15,000 under the revolving credit facility were drawn by the Partnership and were used on the same date to prepay $60,125 of the outstanding debt of GAS-nineteen Ltd., GAS-twenty Ltd. and GAS-twenty one Ltd. under the junior tranche of the Five Vessel Refinancing, which would have been originally due in April 2018. The Partnership repaid $15,000 under the revolving credit facility of the New Sponsor Credit Facility on May 22, 2017. The New Sponsor Credit Facility is unsecured and the revolving credit facility provides for an availability period of five years. Each borrowing under the New Sponsor Credit Facility accrues interest at a rate of 9.125% per annum with an annual 1.0% commitment fee on the undrawn balance. On March 23, 2018, the outstanding amount of $45,000 under the New Sponsor Credit Facility was prepaid.

As of December 31, 2019, the outstanding balance of the New Sponsor Credit Facility is nil. The New Sponsor Credit Facility contains customary events of default, including non-payment of principal or interest, breach of covenants or material inaccuracy of representations, default under other material indebtedness and bankruptcy. In addition, the New Sponsor Credit Facility covenants require that at all times GasLog must continue to control, directly or indirectly, the affairs or composition of the Partnership’s board of directors and any amendment to our Partnership Agreement, in the reasonable opinion of the lender, must not be adverse to its interests in connection with the New Sponsor Credit Facility.

For the years ended December 31, 2017 and December 31, 2018, the annual service fee was $632 and $812 per vessel per year, respectively. With effect from January 1, 2019, the service fee was amended to $608 per vessel per year. With effect from January 1, 2020, the service fee was reduced to $523 per vessel per year. (iii) Ship Management Agreements Upon completion of the IPO on May 12, 2014, each of the vessel owning subsidiaries of the Initial Fleet entered into an amended ship management agreement (collectively, the “Amended Ship Management Agreements”) under which the vessel owning subsidiaries pay a management fee of $46 per month to the Manager and reimburse the Manager for all expenses incurred on their behalf. The Amended Ship Management Agreements also provide for superintendent fees of $1 per day payable to the Manager for each day in excess of 25 days per calendar year for which a superintendent performed visits to the vessels, an annual incentive bonus of up to $72 based on key performance indicators predetermined annually and contain clauses for decreased management fees in case of a vessel’s lay-up. The management fees are subject to an annual adjustment, agreed between the parties in good faith, on the basis of general inflation and proof of increases in actual costs incurred by the Manager. Each Amended Ship Management Agreement continues indefinitely until terminated by either party. The same provisions are included in the ship management agreements that GAS-sixteen Ltd., GAS-seventeen Ltd., GAS-nineteen Ltd., GAS-twenty Ltd., GAS-twenty one Ltd. and GAS-twenty seven Ltd. entered into with the Manager upon the deliveries of the Methane Rita Andrea , the Methane Jane Elizabeth , the Methane Alison Victoria , the Methane Shirley Elisabeth , the Methane Heather Sally and the Methane Becki Anne , respectively, into GasLog’s fleet in April 2014, June 2014 and March 2015 (together with the Amended Ship Management Agreements and the ship management agreement that GAS-seven Ltd. entered into with the Manager upon its vessel’s delivery from the shipyard in 2013, the “Ship Management Agreements”). In May 2015, the Ship Management Agreements were further amended to delete the annual incentive bonus and superintendent fees clauses and, in the case of GAS-seven Ltd., to also increase the fixed monthly charge to $46 with effect from April 1, 2015. In April 2016, the Ship Management Agreements were amended to consolidate all ship management related fees into a single fee structure. This single fee structure was already provided for in the ship management agreements that GAS-eleven Ltd., GAS-twelve Ltd., GAS-thirteen Ltd. and GAS-fourteen Ltd. had entered into with GasLog upon the deliveries of the GasLog Greece in March 2016, the GasLog Glasgow in June 2016, the GasLog Geneva in September 2016 and the GasLog Gibraltar in October 2016, respectively (with a fixed monthly charge of $46).

The agreement covers the supply of ballast water management systems on board the vessels by Samsung and associated field, commissioning and engineering services for a firm period of six years. Various claims, suits and complaints, including those involving government regulations, arise in the ordinary course of the shipping business. In addition, losses may arise from disputes with charterers, environmental claims, agents and insurers and from claims with suppliers relating to the operations of the Partnership’s vessels. Currently, management is not aware of any such claims or contingent liabilities requiring disclosure in the consolidated financial statements.

Financial Risk Management

Financial Risk Management
Financial Risk Management	16. Financial Risk Management The Partnership’s activities expose it to a variety of financial risks, including market risk, liquidity risk and credit risk. The Partnership’s overall risk management program focuses on the unpredictability of financial markets and seeks to minimize potential adverse effects on the Partnership’s financial performance. The Partnership makes use of derivative financial instruments such as interest rate swaps and forward foreign exchange contracts to mitigate certain risk exposures. Market risk Interest Rate Risk: The Partnership is subject to market risks relating to changes in interest rates because it has floating rate debt outstanding. Significant increases in interest rates could adversely affect the Partnership’s results of operations and its ability to service its debt. The Partnership uses interest rate swaps to reduce its exposure to market risk from changes in interest rates. The principal objective of these contracts is to minimize economic risks and costs associated with its floating rate debt and not for speculative or trading purposes. As of December 31, 2019, the Partnership had economically hedged 45.8% of its floating interest rate exposure on its outstanding borrowings (excluding the New Sponsor Credit Facility) by swapping the variable rate for a fixed rate (December 31, 2018: 39.7%). The aggregate principal amount of the Partnership’s outstanding floating rate debt which was not economically hedged as of December 31, 2019 was $740,631 (December 31, 2018: $835,826). As an indication of the extent of the Partnership’s sensitivity to interest rate changes, an increase or decrease in LIBOR of 10 basis points would have decreased or increased, respectively, the profit during the year ended December 31, 2019 by $782, based upon its debt level during the period (December 31, 2018: $933 and December 31, 2017: $1,193). Interest Rate Sensitivity Analysis: The fair value of the interest rate swaps as of December 31, 2019 was estimated as a net liability of $8,868 (December 31, 2018: net asset of $5,513). For the three years ended December 31, 2019, the interest rate swaps were not designated as cash flow hedging instruments (Note 18). The interest rate swap agreements described below are subject to market risk as they are recorded at fair value in the statement of financial position at year end. The fair value of interest rate swap liabilities increases when interest rates decrease and decreases when interest rates increase. As of December 31, 2019, if interest rates had increased or decreased by 10 basis points with all other variables held constant, the positive/(negative) impact, respectively, on the fair value of the interest rate swaps would have amounted to approximately $1,468 (December 31, 2018: $2,021 and December 31, 2017: $1,774) affecting loss/(gain) on swaps in the respective periods. Currency Risk: Currency risk is the risk that the value of financial instruments and/or the cost of commercial transactions will fluctuate due to changes in foreign exchange rates. Currency risk arises when future commercial transactions and recognized assets and liabilities are denominated in a currency that is not the Partnership’s functional currency. The Partnership is exposed to foreign exchange risk arising from various currency exposures primarily with respect to technical maintenance and crew costs denominated in euros. Specifically, for the year ended December 31, 2019, approximately $43,543 of the operating and administrative expenses were denominated in euros (December 31, 2018: $54,222 and December 31, 2017: $42,091). As of December 31, 2019, approximately $11,817 of the Partnership’s outstanding trade payables and accruals were denominated in euros (December 31, 2018: $10,634). The Partnership uses forward foreign exchange contracts to reduce its exposure to movements in exchange rates. As an indication of the extent of the Partnership’s sensitivity to changes in exchange rate, a 10% increase in the average euro/dollar exchange rate would have decreased its profit and cash flows during the year ended December 31, 2019 by $4,354, based upon its expenses during the year (December 31, 2018: $5,422 and December 31, 2017: $4,209). Liquidity risk Liquidity risk is the risk that arises when the maturity of assets and liabilities does not match. An unmatched position potentially enhances profitability but can also increase the risk of losses. The Partnership manages its liquidity risk by having secured credit lines, by receiving capital contributions to fund its commitments and by maintaining cash and cash equivalents. The following tables detail the Partnership’s expected cash flows for its financial liabilities. The tables have been drawn up based on the undiscounted cash flows of financial liabilities based on the earliest date on which the Partnership can be required to pay. The table includes both interest and principal cash flows. Variable future interest payments were determined based on an average LIBOR plus the margins applicable to the Partnership’s loans at the end of each year presented.

The amounts included above for variable interest rate instruments are subject to change if changes in variable interest rates differ from those estimates of interest rates determined at the end of the reporting period. The following tables detail the Partnership’s expected cash flows for its derivative financial instruments. The table has been drawn up based on the undiscounted contractual net cash inflows and outflows on derivative instruments that are settled on a net basis. When the amount payable or receivable is not fixed, the amount disclosed has been determined by reference to the projected interest rates as illustrated by the yield curves existing at the end of the reporting period. The undiscounted contractual cash flows are based on the contractual maturities of the interest rate swaps and forward foreign exchange contracts.

The Partnership expects to be able to meet its long-term obligations resulting from financing its vessels through cash generated from operations. Credit risk Credit risk is the risk that a counterparty will fail to discharge its obligations and cause a financial loss. The Partnership is exposed to credit risk in the event of non-performance by any of its counterparties. To limit this risk, the Partnership currently deals exclusively with financial institutions and customers with high credit ratings. As of December 31, 2018 2019 Cash and cash equivalents 133,370 96,884 Short-term investments 10,000 — Trade and other receivables 13,811 7,147 Derivative financial instruments, current and non-current portion 9,731 372 For the years ended December 31, 2017, December 31, 2018 and December 31, 2019, 100%, 93% and 83%, respectively, of the Partnership’s revenue was earned from subsidiaries of Royal Dutch Shell plc (“Shell”) and accounts receivable were not collateralized; however, management believes that the credit risk is partially offset by the creditworthiness of the Partnership’s principal counterparty and the fact that the hire is being collected in advance. The Partnership did not experience any credit losses on its accounts receivable portfolio during the three years ended December 31, 2019. The carrying amount of financial assets recorded in the consolidated financial statements represents the Partnership’s maximum exposure to credit risk. Management monitors exposure to credit risk and believes that there is no substantial credit risk arising from the Partnership’s counterparty. The credit risk on liquid funds and derivative financial instruments is limited because the direct and indirect counterparties are banks with high credit ratings assigned by international credit rating agencies.

Under the interest rate swaps, the counterparty effects quarterly floating-rate payments to the Partnership for the notional amount based on the three-month U.S. dollar LIBOR, and the Partnership effects quarterly payments to the counterparty on the notional amount at the respective fixed rates. Interest rate swaps held for trading The principal terms of the interest rate swaps held for trading were as follows: Fixed Notional Amount Trade Effective Termination Interest December 31, December 31, Company Counterparty Date Date Date Rate 2018 2019 GasLog Partners GasLog Nov 2016 Nov 2016 July 2020 % 130,000 130,000 GasLog Partners GasLog Nov 2016 Nov 2016 July 2021 % 130,000 130,000 GasLog Partners GasLog Nov 2016 Nov 2016 July 2022 % 130,000 130,000 GasLog Partners GasLog July 2017 July 2017 June 2022 % 80,000 80,000 GasLog Partners GasLog May 2018 May 2018 April 2023 % 80,000 80,000 GasLog Partners GasLog Dec 2018 Jan 2019 Jan 2024 % N/A 75,000 550,000 625,000 The derivative instruments listed above were not designated as cash flow hedging instruments as of December 31, 2019. The change in the fair value of the interest rate swaps for the year ended December 31, 2019 amounted to a loss of $14,381 (December 31, 2018, $833 loss and December 31, 2017: $2,174 gain), which was recognized in profit or loss in the year incurred and is included in Gain/(loss) on derivatives. During the year ended December 31, 2019, the loss of $14,381 was attributable to changes in the LIBOR yield curve, which was used to calculate the present value of the estimated future cash flows, resulting in an increase in net derivative liabilities and a decrease in net derivative assets, respectively, from interest rate swaps held for trading. Forward foreign exchange contracts The Partnership uses non-deliverable forward foreign exchange contracts to mitigate foreign exchange transaction exposures in Euros and Singapore Dollars (“SGD”). Under these non-deliverable forward foreign exchange contracts, the counterparties (GasLog and the Partnership) settle the difference between the fixed exchange rate and the prevailing rate on the agreed notional amounts on the respective settlement dates. All forward foreign exchange contracts are considered by management to be part of economic hedge arrangements but have not been formally designated as such. Forward foreign exchange contracts held for trading The principal terms of the forward foreign exchange contracts held for trading are as follows: Fixed Number of Exchange Rate Company Counterparty Trade Date contracts Settlement Date (USD/EUR) Notional Amount GasLog Partners GasLog Aug 2019 6 Jan 2020 - June 2020 1.1260 - 1.1385 € 7,500 GasLog Partners GasLog Dec 2019 12 Jan 2020 - Dec 2020 1.12425 - 1.1456 € 16,800 Total € 24,300 Fixed Number of Exchange Rate Company Counterparty Trade Date contracts Settlement Date (USD/SGD) Notional Amount GasLog Partners GasLog Dec 2019 9 Jan 2020 - Sep 2020 1.3549 $ 2,250 Total $ 2,250 The derivative instruments listed above were not designated as cash flow hedging instruments as of December 31, 2019.

An analysis of (Gain)/loss on derivatives is as follows: For the year ended December 31, 2017 2018 2019 Realized loss/(gain) on interest rate swaps held for trading 2,053 (1,772) (2,358) Realized loss on forward foreign exchange contracts held for trading — 409 1,295 Unrealized (gain)/loss on interest rate swaps held for trading (2,174) 833 14,381 Unrealized loss/(gain) on forward foreign exchange contracts held for trading — 578 (523) Total (gain)/loss on derivatives (121) 48 12,795 Fair value measurements The fair value of the Partnership’s financial assets and liabilities approximate to their carrying amounts at the reporting date. The fair value of derivatives at the end of the reporting period is determined by discounting the future cash flows using the interest rate curves at the end of the reporting period, the estimation of the counterparty risk and the Partnership’s own risk inherent in the contract. The derivatives met Level 2 classification, according to the fair value hierarchy as defined by IFRS 13 Fair Value Measurement. There were no financial instruments in Levels 1 or 3 and no transfers between Levels 1, 2 or 3 during the periods presented. The definitions of the levels, provided by IFRS 13 Fair Value Measurement , are based on the degree to which the fair value is observable: · Level 1 fair value measurements are those derived from quoted prices in active markets for identical assets or liabilities; · Level 2 fair value measurements are those derived from inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (i.e., as prices) or indirectly (i.e., derived from prices); and · Level 3 fair value measurements are those derived from valuation techniques that include inputs for the asset or liability that are not based on observable market data (unobservable inputs).

Earnings per Unit
Earnings per Unit	20. Earnings Per Unit The Partnership calculates earnings per unit by allocating reported profit for each period to each class of units based on the distribution policy for available cash stated in the Partnership Agreement as generally described in Note 6 above. In the three years ended December 31, 2019, the Partnership completed equity offerings of common units and issued general partner units to its general partner in order for GasLog to retain its 2%, as presented in Note 6. Also, on May 16, 2017, the subordination period expired and consequently all 9,822,358 subordinated units held by GasLog converted into common units on a one-for-one basis (Note 6). Finally, on June 30, 2019, the Partnership issued to GasLog 2,490,000 Class B units, which will become eligible for conversion on a one-for-one basis into common units at GasLog’s option on July 1, 2020, July 1, 2021, July 1, 2022, July 1, 2023, July 1, 2024 and July 1, 2025. Basic earnings per unit is determined by dividing profit for the year reported at the end of each period after deducting preference unit distributions by the weighted average number of units outstanding during the period. Diluted earnings per unit is calculated by dividing the profit of the period attributable to common unitholders by the weighted average number of potential ordinary common units assumed to have been converted into common units, unless such potential ordinary common units have an antidilutive effect. For the year ended December 31, 2017 2018 2019 Profit/(loss) for the year 148,098 128,046 (34,769) Less: Profit attributable to GasLog’s operations* (53,981) (25,449) (2,650) Partnership’s profit/(loss) 94,117 102,597 (37,419) Adjustment for: Paid and accrued preference unit distributions (7,749) (22,498) (30,328) Partnership’s profit/(loss) attributable to: 86,368 80,099 (67,747) Common unitholders 76,347 75,879 (66,268) Subordinated unitholders** 5,085 N/A N/A General partner 1,728 1,602 (1,479) Incentive distribution rights *** 3,208 2,618 — Weighted average units outstanding (basic) Common units 36,493,143 42,945,432 46,272,598 Subordinated units** 9,822,358 N/A N/A General partner units 790,819 876,255 975,531 Earnings/(loss) per unit (basic) Common unitholders 2.09 1.77 (1.43) Subordinated unitholders 0.52 N/A N/A General partner 2.18 1.83 (1.52) Weighted average units outstanding (diluted) Common units**** 36,547,545 43,034,117 46,272,598 Subordinated units** 9,822,358 N/A N/A General partner units 790,819 876,255 975,531 Earnings/(loss) per unit (diluted) Common unitholders 2.09 1.76 (1.43) Subordinated unitholders 0.52 N/A N/A General partner 2.18 1.83 (1.52) * Includes profits of: (i) GAS-eleven Ltd. for the period prior to its transfer to the Partnership on May 3, 2017, (ii) GAS-thirteen Ltd. for the period prior to its transfer to the Partnership on July 3, 2017, (iii) GAS-eight Ltd. for the period prior to its transfer to the Partnership on October 20, 2017, (iv) GAS-fourteen Ltd. for the period prior to its transfer to the Partnership on April 26, 2018, (v) GAS-twenty seven Ltd. for the period prior to its transfer to the Partnership on November 14, 2018 and (vi) GAS-twelve Ltd. for the period prior to its transfer to the Partnership on April 1, 2019. While such amounts are reflected in the Partnership’s financial statements because the transfers to the Partnership were accounted for as reorganizations of entities under common control (Note 1), the aforementioned entities were not owned by the Partnership prior to their transfers to the Partnership on the respective dates and accordingly the Partnership was not entitled to the cash or results generated in the period prior to such transfers. ** On May 16, 2017, all 9,822,358 subordinated units converted into common units on a one-for-one basis. For the year ended December 31, 2017, they participated pro rata with all other outstanding common units in distributions of available cash for the three months ended March 31, 2017. Consequently, earnings have been allocated to subordinated units and the weighted average number of subordinated units has been calculated only for the applicable period during which they were entitled to distributions based on the Partnership Agreement. *** The IDRs were eliminated on June 30, 2019 (Note 6). Until their elimination, they represented 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 had been achieved. GasLog held the incentive distribution rights following completion of the Partnership’s IPO. The IDRs could be transferred separately from any other interests, subject to restrictions in the Partnership Agreement (please refer to Note 6). Based on the nature of such right, earnings attributable to IDRs could not be allocated on a per unit basis. **** Includes unvested awards (Note 21) for the years ended December 31, 2017 and 2018; does not include unvested awards and Class B units for the year ended December 31, 2019, because their effect would be anti-dilutive. The 2,490,000 Class B units were issued on June 30, 2019 and are included in the weighted average number of units outstanding for the calculation of diluted EPU from July 1, 2019 and onwards. They will become eligible for conversion on a one-for-one basis into common units at GasLog’s option in six tranches of 415,000 units per annum on July 1 of 2020, 2021, 2022, 2023, 2024 and 2025; as a result, they do not have an impact on the calculation of basic EPU until conversion.

Share-based Compensation On April 1, 2015, April 1, 2016, April 3, 2017, April 2, 2018 and April 1, 2019, the Partnership granted to its executives Restricted Common Units (“RCUs”) and Performance Common Units (“PCUs”) in accordance with its 2015 Long-Term Incentive Plan (the “2015 Plan”). On April 3, 2018, 16,999 RCUs and 16,999 PCUs vested under the Partnership’s 2015 Plan; an additional 24,925 RCUs and 24,925 PCUs vested under the Partnership’s 2015 Plan on April 1, 2019. The details of the aforementioned awards are presented in the following table: Fair value at Awards Number Grant date Expiry date grant date RCUs 16,999 April 1, 2015 n/a $ 24.12 PCUs 16,999 April 1, 2015 n/a $ 24.12 RCUs 24,925 April 1, 2016 n/a $ 16.45 PCUs 24,925 April 1, 2016 n/a $ 16.45 RCUs 26,097 April 3, 2017 n/a $ 23.85 PCUs 26,097 April 3, 2017 n/a $ 23.85 RCUs 24,608 April 2, 2018 n/a $ 23.40 PCUs 24,608 April 2, 2018 n/a $ 23.40 RCUs 26,308 April 1, 2019 n/a $ 22.99 PCUs 26,308 April 1, 2019 n/a $ 22.99 The RCUs and PCUs vest three years after the grant dates subject to the recipients’ continued service; vesting of the PCUs is also subject to the achievement of certain performance targets in relation to total unitholder return. Specifically, the performance measure is based on the total unitholder return (“TUR”) achieved by the Partnership during the performance period, benchmarked against the TUR of a selected group of peer companies. TUR above the 75th percentile of the peer group results in 100% of the award vesting; TUR between the 50th and 75th percentile of the peer group results in 50% of award vesting; TUR below the 50th percentile of the peer group results in none of the award vesting. The holders are entitled to cash distributions that are accrued and settled on vesting. The awards are settled in cash or in common units at the sole discretion of the board of directors or such committee as may be designated by the board to administer the 2015 Plan. These awards have been treated as equity settled because the Partnership has no present obligation to settle them in cash. Fair value The fair value per common unit of the RCUs and PCUs in accordance with the 2015 Plan was determined by using the grant date closing price of $24.12 for the 2015 grant, $16.45 for the 2016 grant, $23.85 for the 2017 grant, $23.40 for the 2018 grant and $22.99 for the 2019 grant and was not further adjusted since the holders are entitled to cash distributions. Movement in RCUs and PCUs during the year The summary of RCUs and PCUs is presented below: Weighted Number of average Aggregate awards contractual life fair value RCUs Outstanding as of January 1, 2018 67,475 1.38 1,429 Granted during the year 24,608 — 576 Vested during the year (16,999) — (410) Outstanding as of December 31, 2018 75,084 1.25 1,595 Granted during the year 26,308 — 605 Vested during the year (24,925) — (410) Outstanding as of December 31, 2019 76,467 1.26 1,790 PCUs Outstanding as of January 1, 2018 67,475 1.38 1,429 Granted during the year 24,608 — 576 Vested during the year (16,999) — (410) Outstanding as of December 31, 2018 75,084 1.25 1,595 Granted during the year 26,308 — 605 Vested during the year (24,925) — (410) Outstanding as of December 31, 2019 76,467 1.26 1,790 The total expense recognized in respect of equity-settled employee benefits for the year ended December 31, 2019 was $1,158 ($1,034 for the year ended December 31, 2018; $850 for the year ended December 31, 2017).

Taxation

Taxation
Taxation	22. Taxation Under the laws of the countries of the Partnership’s incorporation and the vessels’ registration, the Partnership is not subject to tax on international shipping income. However, it is subject to registration and tonnage taxes, which are included in vessel operating costs in the consolidated statement of profit or loss. Under the United States Internal Revenue Code of 1986, as amended (the “Code”), the U.S. source gross transportation income of a ship-owning or chartering corporation, such as the Partnership, is subject to a 4% U.S. Federal income tax without allowance for deduction, unless that corporation qualifies for exemption from tax under Section 883 of the Code and the Treasury Regulations promulgated thereunder. U.S. source gross transportation income consists of 50% of the gross shipping income that is attributable to transportation that begins or ends, but that does not both begin and end, in the United States. The Partnership did not qualify for this exemption for the three years ended December 31, 2019. During the year ended December 31, 2019, the estimated U.S. source gross transportation tax was $978 and was included under “Vessel Operating Costs” (December 31, 2018: $635 and December 31, 2017: $478).

Significant Accounting Polici_2

Significant Accounting Policies (Policies)	12 Months Ended

Significant Accounting Policies
Statement of compliance	Statement of compliance The consolidated financial statements of the Partnership have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (the “IASB”).
Basis of preparation	Basis of preparation The consolidated financial statements have been prepared on the historical cost basis. Historical cost is generally based on the fair value of the consideration given in exchange for assets. The principal accounting policies are set out below. The consolidated financial statements are expressed in U.S. dollars (“USD”), which is the functional currency of the Partnership and each of its subsidiaries because their vessels operate in international shipping markets, in which revenues and expenses are primarily settled in USD and the Partnership’s most significant assets and liabilities are paid for and settled in USD. In considering going concern, management has reviewed the Partnership’s future cash requirements, covenant compliance and earnings projections. As of December 31, 2019, the Partnership’s current assets totaled $109,353 while current liabilities totaled $186,743, resulting in a negative working capital position of $77,390. Management anticipates that the Partnership’s primary sources of funds will be available cash, cash from operations, borrowings under existing debt and future debt and equity financings, if any. Management believes that these sources of funds will be sufficient for the Partnership to meet its liquidity needs and comply with its banking covenants for at least twelve months from the end of the reporting period and therefore it is appropriate to prepare the financial statements on a going concern basis, although there can be no assurance that the Partnership will be able to obtain future debt and equity financing on terms acceptable to the Partnership. On March 3, 2020, the Partnership’s board of directors authorized the consolidated financial statements for issuance and filing.
Basis of consolidation	Basis of consolidation The accompanying consolidated financial statements include the accounts of the Partnership and its subsidiaries assuming that they are consolidated from the date of their incorporation by GasLog, as they were under the common control of GasLog. All intra-group transactions and balances are eliminated on consolidation.
Accounting for revenues and related operating expenses and voyage expenses and commissions	Accounting for (i) revenues and related operating expenses and (ii) voyage expenses and commissions Revenues comprise revenues from time charters for the charter hire of the Partnership’s vessels earned during the period in accordance with existing contracts and gross pool revenues. A time charter represents a contract entered into for the use of a vessel for a specific period of time and a specified daily charter hire rate. Time charter revenue is recognized as earned on a straight-line basis over the term of the relevant time charter starting from the vessel’s delivery to the charterer, except for any off-hire period, when a charter agreement exists, the vessel is made available and services are provided to the charterer and collection of the related revenue is reasonably assured. Unearned revenue includes cash received prior to the reporting date relating to services to be rendered after the reporting date. Accrued revenue represents income recognized in advance as a result of the straight-line revenue recognition in respect of charter agreements that provide for varying charter rates. Under a time charter arrangement, the hire rate per the charter agreement has two components: the lease component and the service component relating to the vessel operating costs. The revenue in relation to the lease component of the agreements is accounted for under IFRS 16 Leases . The revenue in relation to the service component relates to vessel operating expenses, which include expenses that are paid by the vessel owner such as management fees, crew wages, provisions and stores, technical maintenance and insurance expenses. These costs are essential to operating a charter and the charterers receive the benefit of these when the vessel is used during the contracted time and, therefore, these costs are accounted for in accordance with the requirements of IFRS 15 Revenue from Contracts with Customers . Pool revenues are recognized on a gross basis representing time charter revenues earned by a GasLog Partners vessel participating in the pool under charter agreements where GasLog Partners contracts directly with charterers. Revenue is recognized on a monthly basis, when the vessel is made available and services are provided to the charterer during the period, the amount can be estimated reliably and collection of the related revenue is reasonably assured. Time charter hires are received monthly in advance and are classified as liabilities until such time as the criteria for recognizing the revenue as earned are met. Under a time charter arrangement the vessel operating expenses such as management fees, crew wages, provisions and stores, technical maintenance and insurance expenses, as well as broker’s commissions, are paid by the vessel owner, whereas the majority of voyage expenses such as bunkers, port expenses, agents’ fees and extra war risk insurance are paid by the charterer. Management believes that mobilization of a vessel from a previous port of discharge to a subsequent port of loading does not result in a separate benefit for charterers and that the activity is thus incapable of being distinct. This activity is considered to be a required set-up activity to fulfill the contract. Consequently, positioning and repositioning fees and associated expenses should be recognized over the period of the contract, and not at a certain point in time following the adoption of IFRS 15 Revenue from Contracts with Customers . Consequently, positioning fees, repositioning fees and associated voyage expenses are recognized over the period of each contract, to match the recognition of the respective hire revenues realized. All other voyage expenses and vessel operating costs are expensed as incurred, with the exception of commissions, which are also recognized on a pro-rata basis over the duration of the period of the time charter. Bunkers’ consumption included in voyage expenses represents mainly bunkers consumed during vessels’ unemployment and off-hire.
Net pool allocation	Net pool allocation The Partnership because of its participation in the Cool Pool (until June 23, 2019) also received a net allocation from the pool, which was recognized separately in the consolidated statement of profit or loss under “Net Pool Allocation” and represented GasLog Partners’ share of the net revenues earned from the other pool participants’ vessels less the other participants’ share of the net revenues earned by GasLog Partners’ vessels included in the pool. Each participant’s share of the net pool revenues was based on the number of pool points attributable to its vessels and the number of days such vessels participated in the pool.
Financial income and costs	Financial income and costs Interest income, interest expense, other borrowing costs and realized loss on derivatives are recognized on an accrual basis.
Foreign currencies	Foreign currencies Transactions in currencies other than USD are recognized at the rates of exchange prevailing at the dates of the transactions. At the end of each reporting period, monetary assets and liabilities denominated in other currencies are retranslated into USD at the rates prevailing at that date. All resulting exchange differences are recognized in the consolidated statement of profit or loss in the period in which they arise.
Deferred financing costs	Deferred financing costs Commitment, arrangement, structuring, legal and agency fees incurred for obtaining new loans or refinancing existing facilities are recorded as deferred loan issuance costs and classified contra debt while the fees incurred for the undrawn facilities are classified under non-current assets in the statement of financial position and are classified contra debt on the drawdown dates. Deferred financing costs are deferred and amortized to financial costs over the term of the relevant loan, using the effective interest method. When the relevant loan is terminated or extinguished, the unamortized loan fees are written-off in the consolidated statement of profit or loss.
Vessels	Vessels Vessels are stated at cost less accumulated depreciation and any accumulated impairment loss. The initial cost of an asset comprises its purchase price and any directly attributable costs of bringing the asset to its working condition. The cost of an LNG vessel is split into two components, a “vessel component” and a “dry-docking component”. Depreciation for the vessel component is calculated on a straight-line basis, after taking into account the estimated residual values, over the estimated useful life of this major component of the value of the vessels. Residual values are based on management’s estimation of the amount that the Partnership would currently obtain from disposal of its vessels, after deducting the estimated costs of disposal, if the vessels were already of the age and in the condition expected at the end of their useful life. The LNG vessels are required to undergo a dry-docking overhaul every five years that cannot be performed while the vessels are operating to restore their service potential and to meet their classification requirements. The dry-docking component is estimated at the time of a vessel’s delivery from the shipyard or acquisition from the previous owner and is measured based on the estimated cost of the first dry-docking, subsequent to its acquisition, based on the Partnership’s historical experience with similar types of vessels. For subsequent dry-dockings, actual costs are capitalized when incurred. The dry-docking component is depreciated over the period of five years in the case of new vessels, and until the next dry-docking for secondhand vessels (which is performed within five years from the vessel’s last dry-docking). Costs that will be capitalized as part of the future dry-dockings will include a variety of costs incurred directly attributable to the dry-dock, and costs incurred to meet classification and regulatory requirements, as well as expenses related to the dock preparation and port expenses at the dry-dock shipyard, general shipyard expenses, expenses related to hull, external surfaces and decks, expenses related to machinery and engines of the vessel, as well as expenses related to the testing and correction of findings related to safety equipment on board. Dry-docking costs do not include vessel operating expenses such as replacement parts, crew expenses, provisions, lubricants consumption, insurance, management fees or management costs during the dry-docking period. Expenses related to regular maintenance and repairs of the vessels are expensed as incurred, even if such maintenance and repair occurs during the same time period as the dry-docking. The expected useful lives are as follows: Vessel LNG vessel component 35 years Dry-docking component 5 years Management estimates the useful life of its vessels to be 35 years from the date of initial delivery from the shipyard. Secondhand vessels are depreciated from the date of their acquisition through their remaining estimated useful life. The useful lives and the depreciation method are reviewed annually to ensure that the method and period of depreciation are consistent with the expected pattern of economic benefits from Partnership’s vessels. The residual value is also reviewed at each financial period end. If expectations differ from previous estimates, the changes are accounted for prospectively in profit or loss in the period of the change and future periods. Management estimates residual value of its vessels to be equal to the product of its lightweight tonnage (“LWT”) and an estimated scrap rate per LWT. Effective December 31, 2019, following management’s annual reassessment, the estimated scrap rate per LWT was decreased. This change in estimate is expected to increase the future annual depreciation by $352. The estimated residual value of the vessels may not represent the fair market value at any time partly because market prices of scrap values tend to fluctuate. The Partnership might revise the estimate of the residual values of the vessels in the future in response to changing market conditions. Ordinary maintenance and repairs that do not extend the useful life of the asset are expensed as incurred. When vessels are sold, they are derecognized and any gain or loss resulting from their disposals is included in profit or loss.
Impairment of vessels	Impairment of vessels All vessels are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Whenever the carrying amount of a vessel exceeds its recoverable amount, an impairment loss is recognized in the consolidated statement of profit or loss. The recoverable amount is the higher of a vessel’s fair value less cost of disposal and “value in use”. The fair value less cost of disposal is the amount obtainable from the sale of a vessel in an arm’s length transaction less the costs of disposal, while “value in use” is the present value of estimated future cash flows expected to arise from the continuing use of a vessel and from its disposal at the end of its useful life. Recoverable amounts are estimated for individual vessels. Each vessel is considered to be a single cash-generating unit. The fair value less cost of disposal of the vessels is estimated from market-based evidence by appraisal that is normally undertaken by professionally qualified brokers.
Reimbursable capital expenditures	Reimbursable capital expenditures Costs eligible for capitalization that are contractually reimbursable by our charterers are recognized on a gross basis in the period incurred under “Vessels”. Concurrently, an equal amount is deferred as a liability and amortized to profit or loss as income over the remaining tenure of the charter party agreement.
Leases	Leases Until December 31, 2018, the Partnership’s leases of vessel communication equipment were classified as operating leases. Payments made under operating leases (net of any incentives received from the lessor) were charged to profit or loss on a straight-line basis over the period of the lease. From January 1, 2019 and onwards, each lease has been recognized as a right-of-use asset, with a corresponding liability recognized at the date at which the leased asset is available for use by the Partnership. Assets and liabilities arising from a lease are initially measured on a present value basis, i.e. at the present value of the minimum lease payments, discounted at the interest rate implicit in the lease, if practicable, or else at the Group’s incremental borrowing rate. The corresponding rental obligations, net of future finance charges, are included in current and non-current liabilities as lease liabilities. Each lease payment is allocated between the liability and finance cost. The finance cost is charged to profit or loss over the lease period so as to produce a constant periodic rate of interest on the remaining balance of the liability for each period. The lease liability is subsequently measured by increasing the carrying amount to reflect interest on the lease liability (using the effective interest rate method) and by reducing the carrying amount to reflect lease payments made. The right-of-use asset is depreciated over its useful life or over the shorter of its useful life and the lease term if there is no reasonable certainty that the Partnership will obtain ownership at the end of the lease term.
Provisions	Provisions Provisions are recognized when the Partnership has a present obligation (legal or constructive) as a result of a past event, it is probable that the Partnership will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. The amount recognized as a provision is the best estimate of the consideration required to settle the present obligation at the end of the reporting period, taking into account the risks and uncertainties surrounding the obligation. Where a provision is measured using the cash flows estimated to settle the present obligation, its carrying amount is the present value of those cash flows. When some or all of the economic benefits required to settle a provision are expected to be recovered from a third party, a receivable is recognized as an asset if it is virtually certain that reimbursement will be received and the amount of the receivable can be measured reliably.
Inventories	Inventories Inventories represent lubricants on board the vessel and, in the event of a vessel not being employed under a charter, bunkers on board the vessel. Inventories are stated at the lower of cost calculated on a first-in, first-out basis, and net realizable value.
Financial instruments	Financial instruments Financial assets and liabilities are recognized when the Partnership has become a party to the contractual provisions of the instrument. All financial instruments are initially recognized at fair value. Transaction costs that are directly attributable to the acquisition or issue of financial assets and financial liabilities (other than financial assets and financial liabilities at fair value through profit or loss) are added to or deducted from the fair value of the financial assets or financial liabilities, as appropriate, on initial recognition. · Cash and cash equivalents Cash represents cash on hand and deposits with banks which are repayable on demand. Cash equivalents represent short-term, highly liquid investments which are readily convertible into known amounts of cash with original maturities of three months or less at the time of purchase that are subject to an insignificant risk of change in value. · Short-term investments Short-term investments represent short-term, highly liquid time deposits placed with financial institutions which are readily convertible into known amounts of cash with original maturities of more than three months but less than 12 months at the time of purchase that are subject to an insignificant risk of change in value. · Trade receivables Trade receivables are carried at the amount expected to be received from the third party to settle the obligation. At each reporting date, all potentially uncollectible accounts are assessed individually for purposes of determining the appropriate allowance for doubtful accounts. Trade receivables are recognized initially at their transaction price and subsequently measured at amortized cost using the effective interest method. Trade receivables are written off when there is no reasonable expectation of recovery. See Note 5 for further information about the Partnership’s accounting for trade receivables. The simplified approach is applied to trade and other receivables and the Partnership recognizes lifetime expected credit losses (“ECLs”) on the trade receivables. Under the simplified approach, the loss allowance is always equal to ECLs. · Borrowings Borrowings are measured at amortized cost, using the effective interest method. Any difference between the proceeds (net of transaction costs) and the settlement of the borrowings is recognized in the statement of profit or loss over the term of the borrowings. · Derivative financial instruments Derivative financial instruments, such as interest rate swaps or forward foreign exchange contracts, are used to economically hedge the Partnership’s exposure to interest rate or foreign exchange rate risks. Derivative financial instruments are initially recognized at fair value and are subsequently remeasured to their fair value at each reporting date. The resulting changes in fair value are recognized in profit or loss immediately, unless the derivative is designated and effective as a hedging instrument, in which case the timing of the recognition in profit or loss depends on the nature of the hedge relationship. Derivatives are presented as assets when their valuation is favorable to the Partnership and as liabilities when unfavorable to the Partnership. Criteria for classifying a derivative instrument in a hedging relationship include: (1) the hedging instrument is expected to be highly effective in achieving offsetting changes in fair value or cash flows attributable to the hedged risk; (2) the effectiveness of the hedge can be reliably measured; (3) there is adequate documentation of the hedging relationships at the inception of the hedge; and (4) for cash flow hedges, the forecasted transaction that is the hedged item in the hedging relationship must be considered highly probable. The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in other comprehensive income. The gain or loss relating to the ineffective portion is recognized immediately in the consolidated statement of profit or loss. Amounts previously recognized in other comprehensive income and accumulated in equity are reclassified to the consolidated statement of profit or loss in the periods when the hedged item affects the consolidated statement of profit or loss. Hedge accounting is discontinued when the Partnership terminates the hedging relationship, when the hedging instrument expires or is sold, terminated or exercised, or when it no longer qualifies for hedge accounting. Any gain or loss accumulated in equity at that time remains in equity and is recognized in the consolidated statement of profit or loss when the hedged item affects the consolidated statement of profit or loss. When a forecast transaction designated as the hedged item in a cash flow hedge is no longer expected to occur, the gain or loss accumulated in equity is recycled immediately to the consolidated statement of profit or loss.
Segment information	Segment information Each vessel-owning company owns one LNG carrier which is operated under a time charter with similar operating and economic characteristics. Consequently, the information provided to the Chief Executive Officer (the Partnership’s chief operating decision maker) to review the Partnership’s operating results and allocate resources is on a consolidated basis for a single reportable segment. Furthermore, when the Partnership charters a vessel to a charterer, the charterer is free to trade the vessel worldwide and, as a result, the disclosure of geographic information is impracticable.
Share-based compensation	Share-based compensation Share-based compensation to executives and others providing similar services is measured at the fair value of the equity instruments on the grant date. Details regarding the determination of the fair value of share-based transactions are set out in Note 21. The fair value determined at the grant date of the equity-settled share-based compensation is expensed on a straight-line basis over the vesting period, based on the Partnership’s estimate of equity instruments that will eventually vest, with a corresponding increase in equity. At the end of each reporting period, the Partnership revises its estimate of the number of equity instruments expected to vest. The impact of the revision of the original estimates, if any, is recognized in the consolidated statement of profit or loss such that the cumulative expense reflects the revised estimate, with a corresponding adjustment to the share-based compensation reserve.
Critical accounting judgments and key sources of estimation uncertainty	Critical accounting judgments and key sources of estimation uncertainty The preparation of the consolidated financial statements in conformity with IFRS requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses recognized in the consolidated financial statements. The Partnership’s management evaluates whether estimates should be made on an ongoing basis, utilizing historical experience, consultation with experts and other methods which management considers reasonable in the particular circumstances. However, uncertainty about these assumptions and estimates could result in outcomes that could require a material adjustment to the carrying amount of the asset or liability in the future. Critical accounting judgments are those that reflect significant judgments of uncertainties and potentially result in materially different results under different assumptions and conditions. Critical accounting judgments In the process of applying the Partnership’s accounting policies, management has made the following judgments, apart from those involving estimations, that had the most significant effect on the amounts recognized in the consolidated financial statements. Classification of the Partnership interests: The interests in the Partnership comprise common units, preference units, a general partner interest and incentive distribution rights. Under the terms of the Partnership Agreement, the Partnership is required to distribute 100% of available cash (as defined in the Partnership Agreement) with respect to each quarter within 45 days of the end of the quarter to the partners. Available cash can be summarized as cash and cash equivalents less an amount equal to cash reserves established by the board of directors to (i) provide for the proper conduct of the business of the Partnership group (including reserves for future capital expenditures and for anticipated future credit needs of the Partnership group) subsequent to such quarter, (ii) comply with applicable law or any loan agreement, security agreement, mortgage, debt instrument or other agreement or obligation to which any Partnership group member is a party or by which it is bound or its assets are subject and/or (iii) provide funds for certain distributions relating to future periods. In reaching a judgment as to whether the interests in the Partnership should be classified as liabilities or equity interests, the Partnership has considered the wide discretion of the board of directors to determine whether any portion of the amount of cash available to the Partnership constitutes available cash and that it is possible that there could be no available cash. In the event that there is no available cash, as determined by the board of directors, the Partnership does not have a contractual obligation to make a distribution. Accordingly, management has concluded that the Partnership interests do not represent a contractual obligation on the Partnership to deliver cash and therefore should be classified as equity within the financial statements. Key sources of estimation uncertainty are as follows: Impairment of vessels: The Partnership evaluates the carrying amounts of each of its vessels to determine whether there is any indication that those vessels have suffered an impairment loss by considering both internal and external sources of information. If any such indication exists, the recoverable amount of vessels is estimated in order to determine the extent of the impairment loss, if any. The total carrying amount of the Partnership’s vessels as of December 31, 2019, was $2,286,430 (December 31, 2018: $2,509,283). Recoverable amount is the higher of fair value less costs to sell and value in use. The Partnership’s estimates of recoverable value assume that the vessels are all in seaworthy condition without need for repair and certified in class without notations of any kind. In assessing the fair value less cost to sell of the vessel, the Partnership obtains charter-free market values for its vessels from independent and internationally recognized ship brokers on a semi-annual basis, which are also commonly used and accepted by the Partnership’s lenders for determining compliance with the relevant covenants in the Partnership’s credit facilities. Vessel values can be highly volatile, so the charter-free market values may not be indicative of the future market value of the Partnership’s vessels, or prices that could be achieved if it were to sell them. In assessing value in use, the estimated future cash flows are discounted to their present value using a discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the estimates of future cash flows have not been adjusted. The projection of cash flows related to vessels is complex and requires management to make various estimates including future charter rates, vessel operating expenses and the discount rate. As of December 31, 2019, the carrying amounts of each of the five steam turbine propulsion (“Steam”) vessels (the Methane Rita Andrea , the Methane Jane Elizabeth , the Methane Alison Victoria , the Methane Shirley Elisabeth and the Methane Heather Sally ) and three TFDE vessels (the GasLog Seattle , the Solaris and the Methane Becki Anne ) were higher than the charter-free market values estimated by ship brokers. The Partnership concluded that this, together with certain other events and circumstances (as further described in Note 3), indicated the existence of potential impairment of these vessels. As a result, the Partnership performed an impairment assessment for these vessels by comparing their values in use, being the discounted projected net operating cash flows for these vessels to their carrying values. The Partnership’s strategy is to charter its vessels on term contracts, providing the Partnership with contracted stable cash flows. The assumptions that the Partnership used in its discounted projected net operating cash flow analysis included, among others, utilization, operating revenues, voyage expenses and commissions, dry-docking costs, operating expenses (including vessel management costs), residual values and the discount rate. The key assumptions, being those to which the outcome of the impairment assessment is most sensitive, are the estimate of charter rates for non-contracted revenue days and the discount rate. Revenue assumptions were based on contracted time charter rates up to the end of the current contract for each vessel, as well as the estimated average time charter rates for the remaining life of the vessel after the completion of its current contract. The revenue assumptions exclude days of scheduled off-hire based on the fleet’s historical performance and internal forecasts. The estimated daily time charter rates used for non-contracted revenue days after the completion of the current time charter are based on a combination of (i) recent charter market rates, (ii) conditions existing in the LNG market as of December 31, 2019, (iii) historical average time charter rates, based on publications by independent third party maritime research services (“maritime research publications”), (iv) estimated future time charter rates, based on maritime research publications that provide such forecasts and (v) management’s internal assessment of long-term charter rates achievable by each class of vessel. More specifically, for vessels whose charters will expire within 2020, the estimated charter rates and utilization for the first year from the reporting date were based on the approved annual budget for the year, which was formed based on the anticipated market conditions for 2020 and the latest available maritime research publications from ship brokers for short-term (less than 12 months) employment of a vessel operating in the spot market on less than one-year time charter contracts. For non-contracted periods starting on January 1, 2021 for already expired charters or upon the expiration of the firm charter period of a vessel within 2021 and up to December 31, 2024, the Partnership used the most recent charter market rate for a 5-year time charter rate based on available data from maritime research publications, which is $45 per day for the Steam vessels and $65 per day for the TFDE vessels. Such rates are lower than prevailing spot rates as of December 31, 2019. For the remaining period from January 1, 2025, through the end of each vessel’s useful life (for non-contracted periods), the estimated average time charter rates for Steam and TFDE vessels were based on analysis of future supply and demand for LNG, analysis of future LNG shipping supply and demand balances, internally estimated and market-derived costs of building and financing newbuild LNG vessels, the technical characteristics of each vessel and an assessment of the appropriate discount for Steam and TFDE vessels’ charter rates compared to modern newbuild LNG carriers, which is driven largely by unit freight cost differentials and utilization of such vessels. Recognizing that the LNG industry is cyclical and subject to significant volatility based on factors beyond the Partnership’s control, management believes that the use of the revenue estimates discussed above to be reasonable as of the reporting date. The Partnership has assumed no inflation or any other revenue escalation or growth factors in determining forecasted time charter rates beyond the contracted charter period through the end of a vessel’s useful life, consistent with long-run historical evidence. The Partnership used an annual operating expenses escalation factor equal to 1% based on its historical data and experience, as well as its expectations of future inflation and operating and dry-docking costs. Estimates for the remaining useful lives of the current fleet and residual and scrap values are the same as those used for the Partnership's depreciation policy. All estimates used and assumptions made were in accordance with the Partnership’s internal budgets and historical experience of the shipping industry. In the Partnership’s impairment assessment, the rate used to discount future estimated cash flows to their present values was 7.0% to 7.25% as of December 31, 2019 (7.0% as of December 31, 2018). This was based on an estimated weighted average cost of capital calculated using cost of equity and cost of debt components, adjusted also for vessel-specific risks and uncertainties. The values in use for the five Steam vessels calculated as per above were lower than the respective carrying amounts of those vessels and, consequently, an impairment loss of $138,848 was recognized in the year ended December 31, 2019 (Note 3). The values in use for each of the TFDE vessels with indicators of impairment were greater than their respective carrying amounts, and therefore no impairment loss was recognized for these vessels. In connection with the impairment testing of our vessels as of December 31, 2019, we performed a sensitivity analysis on the most difficult, subjective, or complex assumptions that have the potential to affect the outcome of the impairment assessment, which are the projected charter hire rate used to forecast future cash flows for non-contracted revenue days and the discount rate used, in particular for the Steam vessels (Note 3). It is reasonably possible that changes to these assumptions within the next financial year could require a material adjustment of the carrying amount of the Partnership’s Steam vessels.
Adoption of new and revised IFRS	Adoption of new and revised IFRS (a) Standards and interpretations adopted in the current period The following standards and amendments relevant to the Partnership were effective in the current year: In January 2016, the IASB issued IFRS 16 Leases , which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract, i.e. the customer (“lessee”) and the supplier (“lessor”). IFRS 16 eliminates the classification of leases by lessees as either operating leases or finance leases and, instead, introduces a single lessee accounting model. Applying that model, a lessee is required to recognize: (a) assets and liabilities for all leases with a term of more than 12 months, unless the underlying asset is of low value; and (b) depreciation of lease assets separately from interest on lease liabilities in the statement of profit or loss. Lessors continue to classify their leases as operating leases or finance leases, and to account for those two types of leases differently. IFRS 16 Leases supersedes the previous leases Standard, IAS 17 Leases , and related Interpretations. The standard was effective from January 1, 2019. The Partnership leases various types of vessels’ equipment. Rental contracts are typically made for fixed periods but may have extension options. Lease terms are negotiated on an individual basis and contain a wide range of different terms and conditions. Following the implementation of IFRS 16, a lease is recognized as a right-of-use asset and a corresponding liability on the date when the leased asset is available for use by the Partnership. Each lease payment is allocated between the liability and finance cost. The finance cost is charged to profit or loss over the lease period to produce a constant periodic rate of interest on the remaining balance of the liability for each period. The right-of-use asset is depreciated over the shorter of the asset’s useful life and the lease term on a straight-line basis. Assets and liabilities arising from a lease are initially measured on a present value basis. Lease liabilities include the net present value of the following lease payments: (a) fixed payments (including in-substance fixed payments), less any lease incentives receivable, (b) variable lease payments that are based on an index or a rate (if any), (c) amounts expected to be payable by the lessee under residual value guarantees (if any), (d) the exercise price of a purchase option if the lessee is reasonably certain to exercise that option, and (e) payments of penalties for terminating the lease, if the lease term reflects the lessee exercising that option. The lease payments are discounted using the interest rate implicit in the lease, if that rate can be determined, or the Partnership’s incremental borrowing rate. Right-of-use assets are measured at cost comprising the following: (a) the amount of the initial measurement of lease liability, (b) any lease payments made at or before the commencement date less any lease incentives received, (c) any initial direct costs, and (d) any restoration costs. Payments associated with short-term leases and leases of low-value assets are recognized on a straight-line basis as an expense in profit or loss. Short-term leases are leases with a lease term of 12 months or less. For leases where the Partnership is the lessee, the Partnership has elected to apply the simplified approach, by which comparative information is not restated and any adjustment is recognized at the date of initial application of IFRS 16 Leases . In addition, the Group has elected to apply the exemption for short-term leases or leases of low-value assets where available. The adoption of the standard on January 1, 2019, resulted in an increase in total assets of $1,585, an increase in retained earnings of $192 and an increase in total liabilities of $1,393. All other IFRS standards and amendments that became effective in the current period are not relevant to the Partnership or are not material with respect to the Partnership’s financial statements. (b) Standards and amendments in issue not yet adopted At the date of authorization of these consolidated financial statements, the following standard relevant to the Partnership was in issue but not yet effective: In October 2018, the IASB issued amendments to IFRS 3 Business Combinations with respect to the definition of a business. The amendments are intended to assist entities to determine whether a transaction should be accounted for as a business combination or as an asset acquisition. The amendments clarify the minimum requirements for a business, remove the assessment of whether market participants are capable of replacing any missing elements, add guidance to help entities assess whether an acquired process is substantive, narrow the definitions of a business and of outputs and introduce an optional fair value concentration test. The amendments will be effective for annual periods beginning on or after January 1, 2020. Management anticipates that the implementation of this standard will not have a material impact on the Partnership’s financial statements, since the acquisitions of vessel-owning entities from GasLog continue to be assessed as business acquisitions under the revised definition as well. The impact of all other IFRS standards and amendments issued but not yet adopted is not expected to be material with respect to the Partnership’s financial statements.

The annual commercial management fee under the amended agreements is $360 for each vessel payable quarterly in advance in lump sum amounts. In December 2013, GAS-seven Ltd. entered into a commercial management agreement with GasLog for an annual commercial management fee of $540 that was amended to $360 when the vessel was acquired by the Partnership on November 1, 2016. Additionally, in June 2015, GAS-eight Ltd. entered into a commercial management agreement with GasLog for an annual commercial management fee of $360. The same provisions are included in the commercial management agreements that GAS-eleven Ltd., GAS-twelve Ltd., GAS-thirteen Ltd., GAS-fourteen Ltd., GAS-sixteen Ltd., GAS-seventeen Ltd., GAS-nineteen Ltd., GAS-twenty Ltd., GAS-twenty one Ltd. and GAS-twenty seven Ltd. entered into with GasLog upon the deliveries of the GasLog Greece , the GasLog Glasgow , the GasLog Geneva , the GasLog Gibraltar , the Methane Rita Andrea , the Methane Jane Elizabeth , the Methane Alison Victoria , the Methane Shirley Elisabeth , the Methane Heather Sally and the Methane Becki Anne , respectively, into GasLog’s fleet in March 2016, June 2016, September 2016, October 2016, April 2014, June 2014 and March 2015 (together with the Amended Commercial Management Agreements and the commercial management agreements entered into by GAS-seven Ltd. and GAS-eight Ltd. with GasLog, the “Commercial Management Agreements”). (ii) Administrative Services Agreement Upon completion of the IPO on May 12, 2014, the Partnership entered into an administrative services agreement (the “Administrative Services Agreement”) with GasLog, pursuant to which GasLog will provide certain management and administrative services. The services provided under the Administrative Services Agreement are provided as the Partnership may direct, and include bookkeeping, audit, legal, insurance, administrative, clerical, banking, financial, advisory, client and investor relations services. The Administrative Services Agreement will continue indefinitely until terminated by the Partnership upon 90 days’ notice for any reason in the sole discretion of the Partnership’s board of directors.

(iii) Ship Management Agreements Upon completion of the IPO on May 12, 2014, each of the vessel owning subsidiaries of the Initial Fleet entered into an amended ship management agreement (collectively, the “Amended Ship Management Agreements”) under which the vessel owning subsidiaries pay a management fee of $46 per month to the Manager and reimburse the Manager for all expenses incurred on their behalf. The Amended Ship Management Agreements also provide for superintendent fees of $1 per day payable to the Manager for each day in excess of 25 days per calendar year for which a superintendent performed visits to the vessels, an annual incentive bonus of up to $72 based on key performance indicators predetermined annually and contain clauses for decreased management fees in case of a vessel’s lay-up.

Each Amended Ship Management Agreement continues indefinitely until terminated by either party. The same provisions are included in the ship management agreements that GAS-sixteen Ltd., GAS-seventeen Ltd., GAS-nineteen Ltd., GAS-twenty Ltd., GAS-twenty one Ltd. and GAS-twenty seven Ltd. entered into with the Manager upon the deliveries of the Methane Rita Andrea , the Methane Jane Elizabeth , the Methane Alison Victoria , the Methane Shirley Elisabeth , the Methane Heather Sally and the Methane Becki Anne , respectively, into GasLog’s fleet in April 2014, June 2014 and March 2015 (together with the Amended Ship Management Agreements and the ship management agreement that GAS-seven Ltd. entered into with the Manager upon its vessel’s delivery from the shipyard in 2013, the “Ship Management Agreements”).

In April 2016, the Ship Management Agreements were amended to consolidate all ship management related fees into a single fee structure.

While such amounts are reflected in the Partnership’s financial statements because the transfers to the Partnership were accounted for as reorganizations of entities under common control (Note 1), the aforementioned entities were not owned by the Partnership prior to their transfers to the Partnership on the respective dates and accordingly the Partnership was not entitled to the cash or results generated in the period prior to such transfers. ** On May 16, 2017, all 9,822,358 subordinated units converted into common units on a one-for-one basis. For the year ended December 31, 2017, they participated pro rata with all other outstanding common units in distributions of available cash for the three months ended March 31, 2017. Consequently, earnings have been allocated to subordinated units and the weighted average number of subordinated units has been calculated only for the applicable period during which they were entitled to distributions based on the Partnership Agreement. *** The IDRs were eliminated on June 30, 2019 (Note 6). Until their elimination, they represented 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 had been achieved. GasLog held the incentive distribution rights following completion of the Partnership’s IPO. The IDRs could be transferred separately from any other interests, subject to restrictions in the Partnership Agreement (please refer to Note 6). Based on the nature of such right, earnings attributable to IDRs could not be allocated on a per unit basis. **** Includes unvested awards (Note 21) for the years ended December 31, 2017 and 2018; does not include unvested awards and Class B units for the year ended December 31, 2019, because their effect would be anti-dilutive. The 2,490,000 Class B units were issued on June 30, 2019 and are included in the weighted average number of units outstanding for the calculation of diluted EPU from July 1, 2019 and onwards. They will become eligible for conversion on a one-for-one basis into common units at GasLog’s option in six tranches of 415,000 units per annum on July 1 of 2020, 2021, 2022, 2023, 2024 and 2025; as a result, they do not have an impact on the calculation of basic EPU until conversion.
