Corporate Information And Statement Of IFRS Compliance [Abstract]
General information and significant accounting policies	General information and significant accounting policies Company Scorpio Tankers Inc. and its subsidiaries (together “we”, “our” or the “Company”) are engaged in the seaborne transportation of refined petroleum products in the international shipping markets. Scorpio Tankers Inc. was incorporated in the Republic of the Marshall Islands on July 1, 2009. On April 6, 2010, we closed on our initial public offering, and our common stock currently trades on the New York Stock Exchange under the symbol "STNG." Our fleet, as of December 31, 2021, consisted of 131 owned, sale and leaseback, or bareboat chartered-in product tankers (14 Handymax, 63 MR, 12 LR1 and 42 LR2). Our vessels are commercially managed by Scorpio Commercial Management S.A.M., or SCM, which is majority owned by the Lolli-Ghetti family of which Mr. Emanuele Lauro, our Chairman and Chief Executive Officer, and Mr. Filippo Lauro, our Vice President, are members. SCM’s services include securing employment for our vessels in pools, in the spot market, and on time charters. Our vessels are technically managed by Scorpio Ship Management S.A.M., or SSM, which is majority owned by the Lolli-Ghetti family. SSM facilitates vessel support such as crew, provisions, deck and engine stores, insurance, maintenance and repairs, and other services necessary to operate the vessels such as drydocks and vetting/inspection under a technical management agreement. We also have an administrative services agreement with Scorpio Services Holding Limited, or SSH, which is majority owned by the Lolli-Ghetti family. The administrative services provided under this agreement primarily include accounting, legal compliance, financial, information technology services, and the provision of administrative staff and office space, which are contracted to subsidiaries of SSH. We pay our managers fees for these services and reimburse them for direct or indirect expenses that they incur in providing these services. Basis of accounting The consolidated financial statements incorporate the financial statements of Scorpio Tankers Inc. and its subsidiaries. The consolidated financial statements have been presented in United States dollars, or USD or $, which is the functional currency of Scorpio Tankers Inc. and all its subsidiaries, and have been authorized for issue by the Board of Directors on March 22, 2022. The consolidated financial statements have been prepared in accordance with International Financial Reporting Standards, or IFRS, as issued by the International Accounting Standards Board. All inter-company transactions, balances, income and expenses were eliminated on consolidation. Going concern The financial statements have been prepared in accordance with the going concern basis of accounting as described further in the “Liquidity risk” section of Note 22. Liquidity risk is the risk that an entity will encounter difficulty in raising funds to meet commitments associated with financial instruments. We manage liquidity risk by maintaining adequate reserves and borrowing facilities and by continuously monitoring forecast and actual cash flows. Liquidity risks can manifest themselves when economic conditions deteriorate or when we have significant maturities of our financial instruments. As of December 31, 2021, the financings for four vessels under our Citibank / K-Sure Credit Facility for $76.8 million in aggregate and the financing for one vessel under our Credit Agricole Credit Facility for $16.5 million are scheduled to mature within 2022. Additionally, the financings for three vessels under our Credit Agricole Credit Facility for $49.1 million in aggregate are scheduled to mature during the first quarter of 2023. As described in Note 23, in January and March 2022, we entered into agreements to sell 15 vessels, including all of the vessels that are collateralized under the aforementioned credit facilities, within 12 months from the date of these financial statements. Furthermore, our Convertible Notes due 2022 are scheduled to mature in May 2022 for $69.7 million in aggregate principal amount, and one vessel under our 2021 $21.0 Million Credit Facility for $17.5 million is scheduled to mature in December 2022. While we believe our current financial position, after taking into consideration the pending vessel sales, is adequate to address these cash outflows, a deterioration in economic conditions could cause us to breach the covenants under our financing arrangements and could have a material adverse effect on our business, results of operations, cash flows and financial condition. These circumstances could cause us to seek covenant waivers from our lenders and to pursue other means to raise liquidity, such as through the sale of vessels or in the capital markets, to meet our obligations. Significant Accounting Policies The following is a discussion of our significant accounting policies that were in effect during the years ended December 31, 2021, 2020, and 2019. Revenue recognition Revenue earned by our vessels is comprised of pool revenue, time charter revenue and voyage revenue. (1) Pool revenue for each vessel is determined in accordance with the profit sharing terms specified within each pool agreement. In particular, the pool manager aggregates the revenues and expenses of all of the pool participants and distributes the net earnings to participants based on: • the pool points attributed to each vessel (which are determined by vessel attributes such as cargo carrying capacity, fuel consumption, and construction characteristics); and • the number of days the vessel participated in the pool in the period . (2) Time charter agreements are when our vessels are chartered to customers for a fixed period of time at rates that are generally fixed, but may contain a variable component based on inflation, interest rates, or current market rates. (3) Voyage charter agreements are charter hires, where a contract is made in the spot market for the use of a vessel for a specific voyage for a specified charter rate. Of these revenue streams, revenue generated in the spot market from voyage charter agreements is within the scope of IFRS 15 - Revenue from Contracts with Customers, which was issued by the International Accounting Standards Board on May 28, 2014 and applied to an entity's first annual IFRS financial statements for a period beginning on or after January 1, 2018. IFRS 15 amended the existing accounting standards for revenue recognition and is based on principles that govern the recognition of revenue at an amount an entity expects to be entitled when products or services are transferred to customers. Revenue generated from pools and time charters is accounted for as revenue earned under operating leases and is therefore within the scope of IFRS 16 - Leases . IFRS 16, Leases , was issued by the International Accounting Standards Board on January 13, 2016 and applied to an entity's first annual IFRS financial statements for a period beginning on or after January 1, 2019. IFRS 16 amended the definition of what constitutes a lease to be a contract that conveys the right to control the use of an identified asset if the lessee has both (i) the right to obtain substantially all of the economic benefits from the use of the identified asset, and (ii) the right to direct the use of the identified asset throughout the period of use. We have determined that our existing pool and time charter-out arrangements meet the definition of leases under IFRS 16, with the Company as lessor, on the basis that the pool or charterer manages the vessels in order to enter into transportation contracts with their customers, and thereby enjoys the economic benefits derived from such arrangements. Furthermore, the pool or charterer can direct the use of a vessel (subject to certain limitations in the pool or charter agreement) throughout the period of use. Moreover, under IFRS 16, we are also required to identify the lease and non-lease components of revenue and account for each component in accordance with the applicable accounting standard. In time charter-out or pool arrangements, we have determined that the lease component is the vessel and the non-lease component is the technical management services provided to operate the vessel. These components are accounted for as follows: • All fixed lease revenue earned under these time charter-out arrangements is recognized on a straight-line basis over the term of the lease. • Lease revenue earned under our pool arrangements is recognized as it is earned, since it is 100% variable. • The non-lease component is accounted for as services revenue under IFRS 15 - Revenue from Contracts with Customers. This revenue is recognized “over time” as the customer (i.e. the pool or the charterer) is simultaneously receiving and consuming the benefits of the service. The accounting for our different revenue streams pursuant to the above accounting standards is therefore summarized as follows: Pool revenue We recognize pool revenue based on quarterly reports from the pools which identifies the number of days the vessel participated in the pool, the total pool points for the period, the total pool revenue for the period, and the calculated share of pool revenue for the vessel. Spot market revenue For vessels operating in the spot market, we recognize revenue ‘over time’ as the customer (i.e. the charterer) is simultaneously receiving and consuming the benefits of the vessel. Under IFRS 15, the performance obligation has been identified as the transportation of cargo from one point to another. Therefore, in a spot market voyage under IFRS 15, revenue is recognized on a pro-rata basis commencing on the date that the cargo is loaded and concluding on the date of discharge. Time charter revenue Time charter revenue is recognized as services are performed based on the daily rates specified in the time charter contract. Voyage expenses Voyage expenses primarily include bunkers, port charges, canal tolls, cargo handling operations and brokerage commissions paid by us under voyage charters for vessels trading in the spot market. Under IFRS 15, voyage costs incurred in the fulfillment of a voyage charter are deferred and amortized over the course of the charter commencing on the date that the cargo is loaded and concluding on the date of discharge. Voyage costs are only deferred if they (i) relate directly to such charter, (ii) generate or enhance resources to be used in meeting obligations under the charter, and (iii) are expected to be recovered. Vessel operating costs Vessel operating costs, which include crewing, repairs and maintenance, insurance, stores, lubricating oil consumption, communication expenses, and technical management fees, are expensed as incurred for vessels that are owned, finance leased or bareboat chartered-in. Earnings / (Loss) per share Basic earnings / (loss) per share is calculated by dividing net income / (loss) attributable to equity holders of the parent by the weighted average number of common shares outstanding. Diluted earnings / (loss) per share is calculated by adjusting the net income / (loss) attributable to equity holders of the parent and the weighted average number of common shares used for calculating basic income / (loss) per share for the effects of all potentially dilutive shares. Such dilutive common shares are excluded when the effect would be to increase earnings per share or reduce a loss per share. In the years ended December 31, 2021, 2020 and 2019, there were potentially dilutive items as a result of our (i) 2013 Equity Incentive Plan (as defined in Note 14), (ii) our Convertible Notes due 2019, (iii) our Convertible Notes due 2022, and (iv) our Convertible Notes due 2025 (all of which are described in Note 12). We apply the if-converted method when determining diluted earnings / (loss) per share. This requires the assumption that all potential ordinary shares with respect to our Convertible Notes due 2019, Convertible Notes due 2022, and Convertible Notes due 2025 have been converted into ordinary shares at the beginning of the period or, if not in existence at the beginning of the period, the date of the issue of the financial instrument or the granting of the rights by which they are granted. Under this method, once potential ordinary shares are converted into ordinary shares during the period, the dividends, interest and other expense associated with those potential ordinary shares will no longer be incurred. The effect of conversion, therefore, is to increase income (or reduce losses) attributable to ordinary equity holders as well as the number of shares in issue. Conversion will not be assumed for purposes of computing diluted earnings per share if the effect would be anti-dilutive. The impact of potentially dilutive items on the calculations of earnings / (loss) per share are set forth in Note 21. Leases In a time or bareboat charter-in arrangement, we pay to lease a vessel for a fixed period of time at rates that are generally fixed, but may contain a variable component based on inflation, interest rates, profit sharing or current market rates. In a time charter-in arrangement, the vessel’s owner is responsible for crewing and other vessel operating costs, whereas these costs are the responsibility of the charterer in a bareboat charter-in arrangement. Prior to the adoption of IFRS 16 - Leases in January 2019, the costs associated with these arrangements were recorded as charterhire expense. IFRS 16 - Leases amended the existing accounting standards to require lessees to recognize, on a discounted basis, the rights and obligations created by the commitment to lease assets on the balance sheet as right-of-use assets and corresponding lease liabilities, unless the term of the lease is 12 months or less. As of December 31, 2021, we had 22 bareboat chartered-in vessels which are being accounted for under IFRS 16, Leases as right of use assets and related lease liabilities. Under IFRS 16, there is no charterhire expense for these vessels as the right of use assets are depreciated on a straight-line basis (through depreciation expense) over the lease term, and the lease liability is amortized over that same period (with a portion of each payment allocated to principal and a portion allocated to interest expense). We recorded charterhire expense during the year ended December 31, 2019 for certain vessels that were bareboat chartered-in for terms that were less than 12 months upon the date of transition to IFRS 16. Foreign currencies The individual financial statements of Scorpio Tankers Inc. and each of its subsidiaries are presented in the currency of the primary economic environment in which we operate (its functional currency), which in all cases is U.S. dollars. For the purpose of the consolidated financial statements, our results and financial position are also expressed in U.S. dollars. In preparing the financial statements of Scorpio Tankers Inc. and each of its subsidiaries, transactions in currencies other than the U.S. dollar are recorded at the rate of exchange prevailing on the dates of the transactions. At the end of each reporting period, monetary assets and liabilities denominated in other currencies are translated into the functional currency at rates ruling at that date. All resultant exchange differences have been recognized in the consolidated statements of income or loss. The amounts charged to the consolidated statements of income or loss during the years ended December 31, 2021, 2020 and 2019 were not significant. Segment reporting During the years ended December 31, 2021, 2020 and 2019, we owned, lease financed, or chartered-in vessels spanning four different vessel classes, Handymax, MR, LR1 and LR2, all of which earn revenues in the seaborne transportation of refined petroleum products in the international shipping markets. Each vessel within these segments also exhibits similar long-term financial performance and similar economic characteristics to the other vessels within the respective vessel class, thereby meeting the aggregation criteria pursuant to IFRS 8 - Operating Segments . We have therefore chosen to present our segment information by vessel class using the aggregated information from the individual vessels. Segment results are evaluated based on reported net income or loss from each segment. The accounting policies applied to the reportable segments are the same as those used in the preparation of our consolidated financial statements. It is not practical to report revenue or non-current assets on a geographical basis due to the global nature of the shipping market. Vessels and drydock Our fleet is measured at cost, which includes the cost of work undertaken to enhance the capabilities of the vessels, less accumulated depreciation and impairment losses. Depreciation is calculated on a straight-line basis to the estimated residual value over the anticipated useful life of the vessel from the date of delivery. We estimate the useful lives of our vessels to be 25 years. Vessels under construction are not depreciated until such time as they are ready for use. The residual value is estimated as the lightweight tonnage of each vessel multiplied by scrap value per ton. The scrap value per ton is estimated taking into consideration the historical four-year average scrap market rates available at the balance sheet date with changes accounted for in the period of change and in future periods. The vessels are required to undergo planned drydocks for replacement of certain components, major repairs and maintenance of other components, which cannot be carried out while the vessels are operating, approximately every 30 months or 60 months depending on the nature of work and external requirements. These drydock costs are capitalized and depreciated on a straight-line basis over the estimated period until the next drydock. In deferred drydocking, we only include direct costs that are incurred as part of the drydocking to meet regulatory requirements, or are expenditures that add economic life to the vessel, increase the vessel’s earnings capacity or improve the vessel’s efficiency. Direct costs include shipyard costs as well as the costs of placing the vessel in the shipyard. Expenditures for normal maintenance and repairs, whether incurred as part of the drydocking or not, are expensed as incurred. For an acquired or newly built vessel, a notional drydock component is allocated from the vessel’s cost. The notional drydock cost is estimated by us, based on the expected costs related to the next drydock, which is based on experience and past history of similar vessels, and carried separately from the cost of the vessel. Subsequent drydocks are recorded at actual cost incurred. The drydock component is depreciated on a straight-line basis to the next estimated drydock. The estimated amortization period for a drydock is based on the estimated period between drydocks. When the drydock expenditure is incurred prior to the expiry of the period, the remaining balance is expensed. During the years ended December 31, 2021, 2020, and 2019, we made investments in exhaust gas cleaning systems, or scrubbers, and ballast water treatment systems, or BWTS. The costs of these systems is primarily being depreciated over the estimated remaining useful life of each vessel, which is our estimate of the useful life of this equipment based on experience with such systems. Additionally, for a newly installed scrubber, a notional component is allocated from the scrubber's cost. The notional scrubber cost is estimated by us, based on the expected related costs that we will incur for this equipment at the next scheduled drydock date and relates to the replacement of certain components and maintenance of other components. This notional scrubber cost is carried separately from the cost of the scrubber. Subsequent costs will be recorded at actual cost incurred. The notional component of the scrubber is depreciated on a straight-line basis to the next estimated drydock date. Asset acquisitions In October 2018, the International Accounting Standards Board ("IASB") issued amendments to the definition of a business in IFRS 3 - Business Combinations. 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 to IFRS 3 are effective for annual reporting periods beginning on or after January 1, 2020 and apply prospectively, however earlier application was permitted. As part of these amendments, the IASB introduced an optional fair value concentration test. The purpose of this test is to permit a simplified assessment of whether an acquired set of activities and assets is a business or an asset. Entities may elect whether or not to apply the concentration test on a transaction-by-transaction basis. The concentration test is met if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets. The test is based on gross assets, not net assets, as the IASB concluded that whether a set of activities and assets includes a substantive process does not depend on how the set is financed. In addition, certain assets are excluded from the gross assets considered in the test. If the test is met, the set of activities and assets is determined not to be a business and no further assessment is needed. If the test is not met, or if an entity elects not to apply the test, a detailed assessment must be performed applying the original requirements in IFRS 3. We early adopted these amendments to IFRS 3 in 2019 and applied them to our September 2019 transaction to acquire the leasehold interests in 19 product tankers from Trafigura Maritime Logistics Pte. Ltd. ("Trafigura"). We refer to this transaction as the "Trafigura Transaction". We have accounted for the Trafigura Transaction as an asset acquisition under the amended guidance set forth under IFRS 3, Business Combinations as substantially all of the fair value of the gross assets acquired was concentrated in a group of similar identifiable assets. Moreover, the leasehold interests acquired as part of the Trafigura Transaction qualified as leases under IFRS 16 . Impairment of goodwill Goodwill arising from our 2017 acquisition of Navig8 Product Tankers Inc. was allocated to the cash generating units within each of the respective reportable segments that are expected to benefit from the synergies of the Merger (LR2s and LR1s). Goodwill is not amortized and is tested annually (or more frequently, if impairment indicators arise) by comparing the aggregate carrying amount of the cash generating units within the reportable segment, plus the allocated goodwill, to their recoverable amounts. The recoverable amount of goodwill is measured by the value in use of the cash generating units within the reportable segment. In assessing value in use, the estimated future cash flows of the reportable segment are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the reportable segment for which the estimates of future cash flows have not been adjusted. If the recoverable amount is determined to be less than the aggregate carrying amount of the assets in each respective operating segment, plus goodwill, then goodwill is reduced to the lower of the recoverable amount or zero. An impairment loss is recognized as an expense immediately. This test was performed in connection with the assessment of the carrying amount of our vessels and related drydock costs and resulted in an impairment charge to the goodwill that was previously allocated to the LR1 segment of $2.6 million at December 31, 2020. Impairment of vessels and drydock, vessels under construction and right of use assets for vessels At each balance sheet date, we review the carrying amount of our vessels and drydock, vessels under construction (if applicable), and right of use assets for vessels to determine whether there is any indication that those assets have suffered an impairment loss. If any such indication exists, the recoverable amount of the vessels and drydock, vessels under construction and right of use assets for vessels is estimated in order to determine the extent of the impairment loss (if any). We treat each vessel and the related drydock as a cash generating unit. Recoverable amount is the higher of the fair value less cost to sell (determined by taking into consideration two valuations from independent ship brokers) and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax 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. Where appropriate, our value in use calculations also incorporate probability weighted assessments of different scenarios (such as potential vessel sales). If the recoverable amount of the cash generating unit is estimated to be less than its carrying amount, the carrying amount of the cash-generating unit is reduced to its recoverable amount. An impairment loss is recognized as an expense immediately. As described in Note 7, our impairment testing at December 31, 2020 resulted in an aggregate impairment charge of $14.2 million as the recoverable amounts of 13 of the MRs in our fleet were less than their carrying amounts. Where an impairment loss subsequently reverses, the carrying amount of the cash generating unit is increased to the revised estimate of its recoverable amount, but so that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognized for the cash generating unit in the prior years. A reversal of impairment is recognized as income immediately. Inventories Inventories consist of lubricating oils and other items including stock provisions, and are stated at the lower of cost and net realizable value. Cost is determined using the first in first out method. Stores and spares are charged to vessel operating costs when purchased. Lubricating oil consumption was $10.0 million, $9.8 million, and $10.3 million for the years ended December 31, 2021, 2020, and 2019, respectively. Lubricating oil consumption is recorded to vessel operating costs. Interests in joint ventures In August 2021, we acquired a minority interest in a portfolio of nine product tankers, consisting of five dual-fuel MR methanol tankers (built between 2016 and 2021) which, in addition to traditional petroleum products, are designed to both carry methanol as a cargo and to consume it as a fuel, along with four ice class 1A LR1 product tankers. As part of this agreement, we acquired a 50% interest in a joint venture that ultimately has a minority interest in the entities that own the vessels for final consideration of $6.7 million. A joint venture is an arrangement where we have joint control and have rights to the net assets of the arrangement, rather than rights to the joint venture's assets and obligations for its liabilities. We account for our interest in this joint venture using the equity method pursuant to IFRS 11 - Joint arrangements . Under this guidance, the investment is initially measured at cost, and the carrying amount of the investment is adjusted in subsequent periods based on our share of profits or losses from the joint venture (adjusted for any fair value adjustments made upon initial recognition). Any distributions received from the joint venture reduce the carrying amount. This investment is described in Note 8. Borrowing costs Borrowing costs directly attributable to the acquisition, construction or production of qualifying assets, which are assets that necessarily take a substantial period of time (for example, the time period necessary to construct a vessel) to get ready for their intended use or sale, are added to the cost of those assets, until such time as the assets are substantially ready for their intended use or sale. Investment income earned on the temporary investment of specific borrowings pending their expenditure on qualifying assets is deducted from the borrowing costs eligible for capitalization. All other borrowing costs are recognized in the consolidated statement of income or loss in the period in which they are incurred. Financial instruments IFRS 9, Financial instruments , sets out requirements for recognizing and measuring financial assets, financial liabilities and some contracts to buy or sell non-financial items. Financial assets and financial liabilities are recognized in our balance sheet when we become a party to the contractual provisions of the instrument. Financial assets All financial assets are recognized and derecognized on a trade date where the purchase or sale of a financial asset is under a contract whose terms require delivery within the timeframe established by the market concerned, and are initially measured at fair value, plus transaction costs, except for those financial assets classified as at fair value through profit or loss, which are initially measured at fair value. Financial assets are classified into the following specified categories: financial assets "at fair value through profit or loss", or FVTPL, "at fair value through other comprehensive income" or at amortized cost on the basis of the Company’s business model for managing financial assets and the contractual cash flow characteristics of the financial asset. Income is recognized on an effective interest basis for debt instruments other than those financial assets classified as at FVTPL. Financial assets at amortized cost Financial assets are measured at amortized cost if both of the following conditions are met: • the financial asset is held within a business model whose objective is to hold financial assets in order to collect contractual cash flows; and • the contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. Financial assets at fair value through other comprehensive income Financial assets are measured at fair value through other comprehensive income if both of the following conditions are met: • the financial asset is held within a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets; and • the contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. Financial assets at FVTPL Financial assets are classified as at FVTPL where the financial asset is held for trading. A financial asset is classified as held for trading if: • it has been acquired principally for the purpose of selling in the near future; or • it is a part of an identified portfolio of financial instruments that we manage together and has a recent actual pattern of short-term profit-taking; or • it is a derivative that is not designated and effective as a hedging instrument. Financial assets at FVTPL are stated at fair value, with any resultant gain or loss recognized in the statement of income or loss. The net gain or loss recognized in income or loss incorporates any dividend or interest earned on the financial asset. Fair value is determined in the manner described in Note 22. Accounts receivable Amounts due from the Scorpio Pools and other receivables that have fixed or determinable payments and are not quoted in an active market are classified as accounts receivable. Accounts receivable without a significant financing component are initially measured at their transaction price and subsequently measured at amortized cost, less any impairment (as discussed below). Interest income is recognized by applying the effective interest rate, except for short-term receivables when the recognition of interest would be immaterial. Impairment of financial assets IFRS 9 introduced the 'expected credit loss' (ECL) model to determine and recognize impairments. ECLs are a probability-weighted estimate of credit losses and are measured as the present value of all cash shortfalls (i.e. the difference between cash flows due to the entity in accordance with the contract and cash flows that we expect to receive). ECLs are discounted at the effective interest rate of the financial asset. Under IFRS 9, credit losses are recognized earlie

Amounts due from the Scorpio Pools relate to income receivables and receivables for working capital contributions which are expected to be collected within one year. The amounts receivable from the Scorpio Pools as of December 31, 2020 included $1.1 million of working capital contributions to the Scorpio Pools which were made on behalf of certain bareboat chartered-in vessels whose leases expired within one year of the balance sheet date. For all owned vessels, we assume that these contributions will not be repaid within 12 months and are therefore considered as non-current within Other Assets on the consolidated balance sheets. For chartered-in vessels we classify the amounts as current (within accounts receivable) or non-current (within Other Assets) according to the expiration of the contract. Insurance receivables primarily represent amounts collectible on our insurance policies in relation to vessel repairs. Freight and time charter receivables represent amounts collectible from customers for our vessels operating on time charter or in the spot market.

(2) Represents the write-offs of fully depreciated equipment and notional drydock costs on certain of our vessels. The following is a summary of the items that were capitalized during the years ended December 31, 2021 and 2020: In thousands of U.S. dollars Drydock (1) Notional component of scrubber (2) Total drydock additions Scrubber BWTS Other equipment Capitalized interest Total vessel additions For the year ended December 31, 2021 $ 27,116 $ 150 $ 27,266 $ 4,073 $ 190 $ 4,945 $ 176 $ 9,384 For the year ended December 31, 2020 33,901 6,900 40,801 127,275 30,686 3,033 1,410 162,404 (1) Additions during the years ended December 31, 2021 and 2020 include new costs accrued in prior periods relating to drydocks, ballast water treatment system, and scrubber installations. (2) For a newly installed scrubber, a notional component of approximately 10% is allocated from the scrubber's cost. The notional scrubber cost is estimated by us, based on the expected related costs that we will incur for this equipment at the next scheduled drydock date and relates to the replacement of certain components and maintenance of other components. This notional scrubber cost is carried separately from the cost of the scrubber. Subsequent costs are recorded at actual cost incurred. The notional component of the scrubber is depreciated on a straight-line basis to the next estimated drydock date. Activity We did not take delivery of any owned vessels during the years ended December 31, 2021 and December 31, 2020, though we did take delivery of four vessels under bareboat charters, as described in Note 6 during the year ended December 31, 2020. As of December 31, 2021, we did not have any newbuildings on order. Ballast Water Treatment Systems In July 2018, we executed an agreement to purchase 55 ballast water treatment systems, or BWTS, from an unaffiliated third-party supplier for total consideration of $36.2 million. These systems have been and are expected to be installed from 2019 through 2023, as each respective vessel under the agreement is due for its International Oil Pollution Prevention, or IOPP, renewal survey. Costs capitalized for these systems include the cost of the base equipment that we have contracted to purchase in addition to directly attributable installation costs, costs incurred for systems that were installed during the period, and installation costs incurred in advance of installations that are expected to occur in subsequent periods. We estimate the useful life of these systems to be for the duration of each vessel's remaining useful life and are depreciating the equipment and related installation costs on this basis. Exhaust Gas Cleaning Systems or Scrubbers We commenced a program to retrofit the substantial majority of our vessels with exhaust gas cleaning systems, or scrubbers. The scrubbers enable our ships to use high sulfur fuel oil, which is less expensive than low sulfur fuel oil, in certain parts of the world. From August 2018 through November 2018, we entered into agreements with two separate suppliers to retrofit a total of 77 of our tankers with such systems for total consideration of $116.1 million (which excludes installation costs). We also obtained options to retrofit additional tankers under these agreements. In June and September 2019, we exercised the option to retrofit an additional 14 and seven of our vessels, respectively, with scrubbers for total consideration of $30.3 million. In April 2020, we reached an agreement to postpone the purchase and installation of scrubbers on 19 vessels. In February 2021, we amended an agreement with respect to the purchase of scrubbers on 19 of our vessels to extend the availability period to purchase these scrubbers. In August 2021, we exercised the option to purchase six scrubbers. During the years ended December 31, 2021 and 2020, we retro-fitted a total of one and 46 of our vessels with scrubbers, respectively. During the year ended December 31, 2020, we retro-fitted a total of 22 vessels with BWTS. We did not install any BWTS during the year ended December 31, 2021. Costs capitalized for these systems include the base equipment and systems purchased, and installation costs incurred. We estimate the useful life of these systems to be for the duration of each vessel's remaining useful life, with the exception of approximately 10% of the equipment cost, which is estimated to require replacement at each vessel's next scheduled drydock. This amount has been allocated as a notional component upon installation. The carrying value of the equipment, related installation costs, and notional component will be depreciated on this basis.

Disclosure of leases [Abstract]
Right of use assets and related lease liabilities	Right of use assets and related lease liabilities On January 1, 2019, we adopted IFRS 16 - Leases, which amended the existing accounting standards to require lessees to recognize the rights and obligations created by the commitment to lease assets on the balance sheet, on the basis of the present value of the lease payments that are not paid at the transition date (or commencement date going forward), discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, an incremental borrowing rate, unless the term of the lease is 12 months or less. We had bareboat charter-in commitments on seven vessels under fixed rate bareboat agreements and 19 vessels under variable rate bareboat agreements during the year ended December 31, 2021 and we had bareboat charter-in commitments on 10 vessels under fixed rate bareboat agreements and 19 vessels under variable rate bareboat agreements during the years ended December 31, 2020, and 2019, which were accounted for under IFRS 16 and are described below. IFRS 16 - Leases - 3 MRs The transition to IFRS 16 resulted in the recognition of right-of-use assets and corresponding liabilities relating to three bareboat chartered-in vessel commitments ( STI Beryl , STI Le Rocher and STI Larvotto ). The bareboat contracts for these three vessels were entered into in April 2017, are scheduled to expire in April 2025, and have a fixed lease payment of $8,800 per vessel per day. We have the option to purchase these vessels beginning at the end of the fifth year of the agreement through the end of the eighth year of the agreement, at market-based prices. Additionally, a deposit of $4.35 million was retained by the buyer and will either be applied to the purchase price of the vessel, if a purchase option is exercised, or refunded to us at the expiration of the agreement. Based on the analysis of the purchase options, we determined the lease terms to be eight years, from the commencement date through the expiration date of each lease. A weighted average incremental borrowing rate of approximately 6.0% was applied at the date of initial application of IFRS 16 on this arrangement. The impact of the application of this standard on the opening balance sheet as of January 1, 2019 was the recognition of a $48.5 million right of use asset, a $50.7 million lease liability ("IFRS 16 - Leases - 3 MRs") and a $2.2 million reduction in retained earnings - a basic loss per share of $(0.05) and a diluted loss per share of $(0.06). The IFRS 16 - Leases - 3 MRs obligations are secured by, among other things, assignments of earnings and insurances and stock pledges and account charges in respect of the subject vessels and contain customary events of default, including cross-default provisions as well as subjective acceleration clauses under which the lessor could cancel the lease in the event of a material adverse change in our business. In April 2020, we executed agreements to increase the borrowing capacity of the three vessels under our IFRS 16 - Leases - 3 MRs obligation by up to $1.9 million per vessel to partially finance the purchase and installation of scrubbers on these vessels. Each agreement will be for a fixed term of three years at the rate of up to $1,910 per vessel per day to be allocated to principal and interest. There have been no borrowings under these agreements as of December 31, 2021. The aggregate outstanding balances of these lease liabilities were $29.3 million and $36.9 million as of December 31, 2021 and 2020, respectively. IFRS 16 - Leases - 7 Handymax In March 2019, we entered into new bareboat charter-in agreements on seven previously bareboat chartered-in vessels. Three of these vessels ( Silent , Single and Star I ) were bareboat chartered-in for one year, and the remaining four vessels ( Steel , Sky , Stone I and Style ) were bareboat chartered-in for two years. The daily bareboat rate under all seven agreements was $6,300 per day. We determined the lease terms to be from the commencement date through the expiration date of each lease. At the commencement date of the leases, we determined our one and two-year incremental borrowing rates to be 5.81% and 5.73%, respectively. We recognized a $24.2 million right of use asset and a corresponding $24.2 million lease liability ("IFRS 16 - Leases - 7 Handymax") at the commencement date of these leases. In March 2020, we extended the terms of the bareboat agreements for three Handymax vessels, Silent and Single to June 2020 and Star I to July 2020, at the rate of $6,300 per day. These extensions were determined to be lease modifications under IFRS 16 - Leases and we therefore recognized additional right of use assets of $1.6 million and corresponding lease liabilities of $1.6 million based upon our incremental borrowing rate of 4.03% as a result of these modifications. The bareboat charters on Silent and Single expired in June 2020, and Star I expired in July 2020. The remaining bareboat charter-in arrangements for four Handymax vessels ( Style, Stone, Steel and Sky ) expired in March 2021. The IFRS 16 - Leases - 7 Handymax obligations were secured by, among other things, assignments of earnings and insurances and stock pledges and account charges in respect of the subject vessels and contain customary events of default, including cross-default provisions. The aggregate outstanding balances of these lease liabilities were $2.2 million as of December 31, 2020. IFRS 16 - Leases - Trafigura Transaction On September 26, 2019, we acquired subsidiaries of Trafigura, which have leasehold interests in 19 product tankers under bareboat charter agreements ("Agreements") with subsidiaries of an international financial institution for aggregate consideration of $803.0 million. Of the 19 vessels, 15 (consisting of 11 MRs and four LR2s) were delivered on September 26, 2019, and four MRs were under construction. The consideration exchanged consisted of: • For the delivered vessels on September 26, 2019, the assumption of the obligations under the Agreements of $531.5 million and the issuance of 3,981,619 shares of common stock at $29.00 per share to a nominee of Trafigura with an aggregate market value of $115.5 million. • For the four vessels under construction on September 26, 2019, the assumption of the estimated commitments on the Agreements of $138.8 million and the issuance of 591,254 shares of common stock at $29.00 per share to a nominee of Trafigura with an aggregate market value of $17.1 million. Three vessels under construction were delivered in the first quarter of 2020, and the remaining vessel was delivered in September 2020, with aggregate final commitments on the Modified Agreements (see below) of $138.8 million. On the date of the Trafigura Transaction, certain terms of the Agreements were modified ("Modified Agreements" and, collectively, "IFRS 16 - Leases - $670.0 Million"). Under IFRS 16- Leases the Modified Agreements did not meet the criteria to qualify as separate leases and were measured accordingly as lease modifications. The Modified Agreements each have a term of eight years from the latter of the date of the Trafigura Transaction or the delivery date of the respective vessel, and we have purchase options beginning after the first year of each agreement, limited to eight vessels until after the third anniversary date. Based on the analysis of the purchase options, we determined the lease terms to be eight years from the commencement date of the Modified Agreements, through the expiration date of each lease, at which time we have assumed that the exercise of the purchase options to be reasonably certain. The Modified Agreements bear interest at LIBOR plus a margin of 3.50% per annum and are being repaid in equal monthly installments of approximately $0.2 million per month per vessel. Additionally, an aggregate prepayment of $18.0 million ($0.8 million for each MR and $1.5 million for each LR2) is being made in equal monthly installments over the first 12 months of each Modified Agreement. Commencing with the date of the Trafigura Transaction, the following vessels were leased under the Modified Agreements: STI Magic , STI Majestic , STI Mystery , STI Marvel , STI Magnetic , STI Millennia , STI Magister , STI Mythic , STI Marshall , STI Modest , STI Maverick , STI Miracle , STI Maestro , STI Mighty , STI Maximus , STI Lobelia, STI Lotus , STI Lily and STI Lavender . The Modified Agreements commenced upon delivery for (i) STI Miracle and STI Maestro in January 2020; (ii) STI Mighty in March 2020; and (iii) STI Maximus in September 2020. The Modified Agreements are secured by, among other things, assignments of earnings and insurances and stock pledges and account charges in respect of the subject vessels and contain customary events of default, including cross-default provisions as well as subjective acceleration clauses under which the lessor could cancel the lease in the event of a material adverse change in our business. The leased vessels are required to maintain a fair value, as determined by an annual appraisal from an approved third-party broker, of 111% of the outstanding principal balance as of the last banking day of the year. At December 31, 2020 we made an unscheduled payment of $0.9 million with respect to one of the vessels to maintain compliance with this covenant. The Trafigura Transaction was accounted for as an asset acquisition in accordance with the early adoption of amendments to the definition of a business in IFRS 3 - Business Combinations effective for annual reporting periods beginning on or after January 1, 2020, and the obligations assumed under the leasehold interests were accounted for under IFRS 16, Leases. Accordingly, we recorded lease liabilities and corresponding right of use assets for the delivered vessels upon the closing date of the Trafigura Transaction. The right of use assets were measured based on (i) the present value of the minimum lease payments under each lease (which assumes the exercise of the purchase options at expiration) of $531.5 million, (ii) the value of the equity issued for each lease (as an initial direct cost) of $115.5 million, and (iii) other initial direct costs of $2.5 million. Additionally, we recorded lease liabilities and corresponding right of use assets upon the delivery of the four MR vessels that were delivered during the year ended December 31, 2020; STI Miracle , STI Maestro , STI Mighty and STI Maximus . The right of use assets for these four vessels were measured based on (i) the present value of the minimum lease payments under each lease (which assumes the exercise of the purchase options at expiration) of $138.8 million, (ii) the value of the equity issued for each lease (as an initial direct cost) of $17.1 million, and (iii) other initial direct costs of $3.0 million (which includes costs incurred as part of the transaction and capitalized costs incurred as part of the construction of each vessel). The aggregate outstanding balances of these lease liabilities were $546.7 million and $593.3 million as of December 31, 2021 and 2020, respectively. We were in compliance with the financial covenants under these agreements as of those dates. The following is the activity of the 'Right of use assets for vessels' starting with the recognition of the assets on January 1, 2020 through December 31, 2021: In thousands of U.S. Dollars Vessels Drydock Total Cost As of January 1, 2021 $ 853,690 $ 23,562 $ 877,252 Other (1) (349) — (349) Fully depreciated assets (1) (17,095) — (17,095) As of December 31, 2021 836,246 23,562 859,808 Accumulated depreciation and impairment As of January 1, 2021 (63,636) (6,437) (70,073) Charge for the period (37,661) (5,125) (42,786) Other (1) (19) — (19) Fully depreciated assets (1) 17,095 — 17,095 As of December 31, 2021 (84,221) (11,562) (95,783) Net book value As of December 31, 2021 $ 752,025 $ 12,000 $ 764,025 (1) This amount represents the adjustment of the lease term and write-off of fully depreciated right of use assets related to the bareboat charters on four fixed rate Handymax vessels that expired in March 2021.

On this basis, the drydock costs for these vessels is being depreciated separately. $4.6 million of notional drydock costs were allocated from the right of use assets recorded for the four MR vessels delivered during 2020 as part of the Trafigura Transaction. (2) This amount represents the write-off of fully depreciated right of use assets related to the bareboat charters on three fixed rate Handymax vessels that expired during the year ended December 31, 2020. The following table summarizes the payments made for the years ended December 31, 2021 and 2020 relating to lease liabilities accounted for under IFRS 16 - Leases : For the year ended December 31, In thousands of U.S. dollars 2021 2020 Interest expense recognized in consolidated statements of income or loss $ 23,641 $ 28,458 Principal repayments recognized in consolidated cash flow statements 56,729 77,913 Net decrease in accrued interest expense 39 (206) Net increase in prepaid interest expense (684) (382) Total payments on lease liabilities under IFRS 16 - Leases $ 79,725 $ 105,783 The undiscounted remaining future minimum lease payments under bareboat charter-in arrangements that are accounted as lease liabilities under IFRS 16 - Leases as of December 31, 2021 are $700.4 million. The obligations under these agreements will be repaid as follows: As of In thousands of U.S. dollars December 31, 2021 Less than 1 year $ 78,211 1 - 5 years 278,633 5+ years 343,526 Total 700,370 Discounting effect (1) (124,372) Prepaid interest expense (621) Lease liability $ 575,377 (1) Represents estimated interest payments using applicable implicit or imputed interest rates in each lease agreement. For leases with implicit rates which include a variable component tied to a benchmark, such as LIBOR, the payments were estimated by taking into consideration: (i) the margin on each lease and (ii) the forward interest rate curve calculated from interest swap rates, as published by a third party, as of December 31, 2021. During the year ended December 31, 2019, our charterhire expense for operating leases was $4.4 million. These lease payments include payments for the non-lease elements in our time chartered-in arrangement that expired in January 2019. We did not incur charterhire expenses during the years ended December 31, 2021 and 2020. Vessels recorded as Right of use assets derive income from subleases through time charter-out and pool arrangements. For the years ended December 31, 2021, 2020 and 2019, sublease income of $91.8 million, $165.8 million and $78.8 million, respectively, is included in Vessel revenue.

Disclosure of impairment of assets [Abstract]
Carrying values of vessels, vessels under construction and goodwill	Carrying values of vessels, vessels under construction, right of use assets for vessels and goodwill At each balance sheet date, we review the carrying amounts of our goodwill, vessels and related drydock costs and right of use assets for vessels to determine if there is any indication that these amounts have suffered an impairment loss. If such indication exists, the recoverable amount of the vessels, right of use assets and related drydock costs is estimated in order to determine the extent of the impairment loss (if any). Recoverable amount is the higher of fair value less costs to sell and value in use. As part of this evaluation, we consider certain indicators of potential impairment, such as market conditions including forecast time charter rates and values for second-hand product tankers, discounted projected vessel operating cash flows, and the Company’s overall business plans. Goodwill arising from our September 2017 acquisition of Navig8 Product Tankers Inc. has been allocated to the cash generating units within each of the respective operating segments that are expected to benefit from the synergies of this transaction (LR2s and LR1s). The carrying value of the goodwill allocated to the LR2 segment was $8.9 million at December 31, 2021. Goodwill relating to the LR1 segment, which was previously allocated for $2.6 million was written off at December 31, 2020. Goodwill is not amortized and is tested annually (or more frequently, if impairment indicators arise) by comparing the aggregate carrying amount of the cash generating units in each respective operating segment, plus the allocated goodwill, to their recoverable amounts. Recoverable amount is the higher of the fair value less cost to sell (determined by taking into consideration vessel valuations from independent ship brokers for each vessel within each segment) and value in use. In assessing value in use, the estimated future cash flows of the operating segment are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the operating segment for which the estimates of future cash flows have not been adjusted. Where appropriate, our value in use calculations also incorporate probability weighted assessments of different scenarios (such as potential vessel sales). This test was performed in connection with the assessment of the carrying amount of our vessels and related drydock costs at December 31, 2021 and an impairment charge was not recorded. At December 31, 2021, we reviewed the carrying amount of our vessels and right of use assets for vessels to determine whether there was an indication that these assets had suffered an impairment. First, we assessed the fair value less the cost to sell of our vessels taking into consideration vessel valuations from independent ship brokers. We then compared the fair value less selling costs to each vessel’s carrying value and, if the carrying value exceeded the vessel’s fair value less selling costs, an indicator of impairment exists. We also considered sustained weakness in the product tanker market or other macroeconomic indications (such as the COVID-19 pandemic) to be an impairment indicator. Based upon these factors, we determined that impairment indicators did exist at December 31, 2021. Once this determination was made, we prepared a value in use calculation where we estimated each vessel’s future cash flows. These estimates were primarily based on (i) our best estimate of forecasted vessel revenue through a combination of the latest forecast, published time charter rates for the next three years and a 2.44% growth rate (which is based on published historical and forecast inflation rates) in freight rates in each period through the vessel's 15th year of useful life and reduced to match the growth in expenses thereafter, (ii) our best estimate of vessel operating expenses and drydock costs, which are based on our most recent forecasts for the next three years and a 2.44% (2.34% in 2020) growth rate in each period thereafter, and (iii) the evaluation of other inputs such as the vessel's remaining useful life, residual value and utilization rate. These cash flows were then discounted to their present value using a pre-tax discount rate of 7.19% (7.24% in 2020). The results of these tests were as follows: At December 31, 2021, our operating fleet consisted of 131 owned, finance leased or right of use vessels ("ROU vessels"). • 43 of our owned, sale and leaseback, or ROU vessels in our fleet had fair values less selling costs greater than their carrying amount. • 85 of our owned, sale and leaseback, or ROU vessels in our fleet had fair values less selling costs lower than their carrying amount. • We did not obtain valuations from independent ship brokers for three of our ROU vessels as they are not required under the respective leases. • We prepared a value in use calculation for all 131 vessels in our fleet which resulted in no impairment charge being recognized. At December 31, 2020, our operating fleet consisted of 135 owned, finance leased or right of use vessels ("ROU vessels"). • Seven of our owned, sale and leaseback, or ROU vessels in our fleet had fair values less selling costs greater than their carrying amount. • 121 of our owned, sale and leaseback, or ROU vessels in our fleet had fair values less selling costs lower than their carrying amount. • We did not obtain valuations from independent ship brokers for seven of our ROU vessels as they were not required under the respective leases. • We prepared a value in use calculation for all 135 vessels in our fleet which resulted in an aggregate impairment charge of $14.2 million on 13 MRs. The recoverable amounts per vessel were approximately $27.0 million for one MR, $29.0 million for four MRs, $34.0 million for three MRs and $35.0 million for five MRs. The factors leading to this impairment charge and the sensitivities thereto, are described further below. Factors leading to the 2020 impairment charges of vessels and goodwill The factors leading to the impairment charges recorded during the year ended December 31, 2020 were shaped by the COVID-19 pandemic. Initially, the onset of the COVID-19 pandemic in March 2020 resulted in a sharp reduction of economic activity and a corresponding reduction in the global demand for oil and refined petroleum products. This period of time was marked by extreme volatility in the oil markets and the development of a steep contango in the prices of oil and refined petroleum products. Consequently, an abundance of arbitrage and floating storage opportunities were created, which resulted in record increases in spot TCE rates during the second quarter of 2020. These market dynamics led to a build-up of global oil and refined petroleum product inventories. In June 2020, the underlying oil markets stabilized, and global economies began to recover, albeit at a slow pace. These conditions led to the gradual unwinding of excess inventories and thus a reduction in spot TCE rates for the remainder of that year. The downward pressure on spot TCE rates led to corresponding reductions in published time charter rates, which are the basis for our impairment calculations (as there are no comparable published longer term forecasts for spot TCE rates). One-year published time charter rates were impacted more meaningfully than three-year published time charter rates which implied that the market was pricing in short-term headwinds as the COVID-19 pandemic stretched into 2021, followed by a longer-term recovery once the COVID-19 pandemic subsides. The recovery that was implied in the longer-term published time charter rates was of material benefit to our calculations given that our vessels had an average age of just 5.2 years as of December 31, 2020 and an estimated useful life of 25 years. In spite of these forecasts, the short-term headwinds that were observed in the one-year time charter rates caused the recoverable amount of 13 of the MRs in our fleet, as determined by the value in use calculations, to be lower than their carrying values by $14.2 million in aggregate as of December 31, 2020. This dynamic also impacted the value in use calculations for the goodwill that was previously allocated to the LR1 reportable segment which resulted in a goodwill impairment charge of $2.6 million. The aggregate value in use calculations in our LR2 reportable segment were sufficient to support the carrying value of its allocated goodwill of $8.9 million, given the positive outlook for this vessel class. There were no reversals of impairment recognized as income during the year ended December 31, 2021. Sensitivities and benchmarking The impairment test that we conducted is most sensitive to variances in the discount rate and future time charter rates. Based on the sensitivity analysis performed for December 31, 2021: • A 1.0% increase in the discount rate would have resulted in 26 vessels being impaired for an aggregate $12.5 million loss, comprised of: 13 MRs for $7.4 million; and 13 Handymax vessels for $5.1 million. • A 5% decrease in forecasted time charter rates, which is between $900 per day and $1,500 per day depending on the vessel class, would have resulted in 46 vessels being impaired for an aggregate $46.0 million loss, comprised of: 32 MRs for $27.5 million; and 14 Handymax vessels for $18.5 million. Based on the sensitivity analysis performed for December 31, 2020: • A 1.0% increase in the discount rate would have resulted in 57 vessels being impaired for an aggregate $103.1 million loss, comprised of: 46 MRs for $90.9 million; and 11 LR1s for $12.2 million. • A 5% decrease in forecasted time charter rates, which is between $900 per day and $1,500 per day depending on the vessel class, would result in 70 vessels being impaired for an aggregate $161.0 million loss, comprised of: 59 MRs for $140.2 million; and 11 LR1s for $20.7 million. We also compared the results of our value in use calculations as of December 31, 2021 to various other scenarios, which can be summarized as follows: • If we used 10-year historical average TCE rates for our value in use calculations, the calculation would result in two vessels being impaired for an aggregate $0.4 million loss, comprised of: one MR for $0.2 million; and one LR1 for $0.2 million. • If we used 15-year historical average TCE rates for our value in use calculations, no impairment loss would be recorded in any of our vessel classes. • If we used 20-year historical average TCE rates for our value in use calculations, no impairment loss would be recorded in any of our vessel classes. While the results of this scenario building exercise support our conclusions, it remains our belief that our base case value in use calculations, through the use of independently published time charter rates, form an objective approximation of forward looking cash flows based on the most recent available data in the market (which incorporates market views on the trajectory of the COVID-19 pandemic, among other factors). Historical averages do not incorporate such perspectives and are also based on time periods when vessel operating expenses were lower (as opposed to our calculations, where we project gradual increases in vessel operating expenses). Capitalized interest In accordance with IAS 23 “Borrowing Costs,” applicable interest costs are capitalized during the period that ballast water treatment systems and scrubbers for our vessels are constructed and installed. For the years ended December 31, 2021 and 2020, we capitalized interest expense for the respective vessels of $0.2 million and $1.4 million, respectively. The capitalization rate used to determine the amount of borrowing costs eligible for capitalization was 1.6% and 3.6% for each of the years ended December 31, 2021 and 2020, respectively. We cease capitalizing interest when the vessels reach the location and condition necessary to operate in the manner intended by management.

Other non-current assets	Other non-current assets The following is a table summarizing the components of our Other non-current assets as of December 31, 2021 and 2020: At December 31, In thousands of U.S. dollars 2021 2020 Scorpio LR2 Pool Ltd. pool working capital contributions (1) $ 35,700 $ 35,700 Scorpio MR Pool Ltd. pool working capital contributions (1) 25,200 25,200 Scorpio LR1 Pool Ltd. pool working capital contributions (1) 6,600 6,600 Scorpio Handymax Tanker Pool Ltd. pool working capital contributions (1) 5,661 5,661 Working capital contributions to Scorpio Pools 73,161 73,161 Deposits for exhaust gas cleaning system ('scrubbers') (2) 15,840 5,617 Seller's credit on sale leaseback vessels (3) 10,793 10,192 Investment in dual fuel tanker joint venture (4) 5,736 — Investment in BWTS supplier (5) 1,751 1,751 Capitalized loan fees (6) 1,635 1,424 Other (7) 47 — $ 108,963 $ 92,145 (1) Upon entrance into the Scorpio LR2, LR1, MR, and Handymax Pools, all vessels are required to make initial working capital contributions of both cash and bunkers. Initial working capital contributions are repaid, without interest, upon a vessel’s exit from the pool. Bunkers on board a vessel exiting the pool are credited against such repayment at the actual invoice price of the bunkers. For all owned vessels, we assume that these contributions will not be repaid within 12 months and are thus classified as non-current within Other Assets on the consolidated balance sheets. For chartered-in vessels we classify the amounts as current (within accounts receivable) or non-current (within Other Assets) according to the expiration of the contract. (2) From August 2018 through September 2019, we entered into agreements with two separate suppliers to retrofit a total of 98 of our tankers with scrubbers for total consideration of $146.6 million (which excludes installation costs). Deposits paid for these systems are reflected as investing cash flows within the consolidated statement of cash flows. In April 2020, we reached an agreement to postpone the purchase and installation of scrubbers on 19 of our vessels. In February 2021, we signed an agreement to retain the option to purchase these scrubbers through February 2023. In August 2021, we declared options to purchase and install scrubbers on six vessels (five LR1s and an LR2). The scrubbers are expected to be installed within the first half of 2022. (3) The seller's credit on vessels sold and leased back represents the present value of the deposits of $4.35 million per vessel ($13.1 million in aggregate) that was retained by the buyer as part of the 2017 sale and operating leaseback transactions for STI Beryl , STI Le Rocher and STI Larvotto , which is described in Note 6. This deposit will either be applied to the purchase price of the vessel if a purchase option is exercised or refunded to us at the expiration of the agreement. The present value of this deposit has been calculated based on the interest rate that is implied in the lease, and the carrying value will accrete over the life of the lease, through interest income, until expiration. We recorded $0.6 million and $0.5 million as interest income as part of these agreements during each of the years ended December 31, 2021 and 2020, respectively. (4) In August 2021, we acquired a minority interest in a portfolio of nine product tankers, consisting of five dual-fuel MR methanol tankers (built between 2016 and 2021) which, in addition to traditional petroleum products, are designed to both carry methanol as a cargo and to consume it as a fuel, along with four ice class 1A LR1 product tankers. The dual-fuel MR methanol tankers are currently on long-term time charter contracts greater than five years. As part of this agreement, we acquired a 50% interest in a joint venture that ultimately has a minority interest in the entities that own the vessels for final consideration of $6.7 million. We account for our interest in this joint venture using the equity method pursuant to IFRS 11 - Joint arrangements . Under this guidance, the investment is initially measured at cost, and the carrying amount of the investment is adjusted in subsequent periods based on our share of profits or losses from the joint venture (adjusted for any fair value adjustments made upon initial recognition). Any distributions received from the joint venture reduce the carrying amount. We recorded $0.6 million as our share of net income resulting from this joint venture during the year ended December 31, 2021. Additionally, the joint venture issued a cash distribution of $1.5 million in December 2021, which arose primarily as a result of the sale of two of the LR1s during the fourth quarter of 2021. (5) In July 2018, we executed an agreement to purchase 55 BWTS from an unaffiliated third-party supplier for total consideration of $36.2 million. These systems were expected to be installed over the subsequent five years, as each respective vessel under the agreement comes due for its International Oil Pollution Prevention, or IOPP, renewal survey. Upon entry into this agreement, we also obtained a minority equity interest in this supplier for no additional consideration. We have determined that of the total consideration of $36.2 million, $1.8 million is attributable to the minority equity interest. Since July 2018, aggregate deposits of $32.8 million have been made, of which $31.0 million has been reclassified to "Vessels" upon the installation of these systems. The remaining $1.8 million of this amount has been recorded as the aforementioned minority equity interest, which is being accounted for as a financial asset under IFRS 9. Deposits paid for these systems are reflected as investing cash flows within the consolidated statement of cash flows. Under the terms of the agreement, we were granted a put option, exercisable after one year following the date of the agreement, whereby we can put the shares back to the supplier at a predetermined price. The supplier was also granted a call option, exercisable two years following the date of the agreement, whereby it can buy the shares back from us at a predetermined price, which is greater than the strike price of the put option. Given that the value of this investment is contractually limited to the strike prices set forth in these options, we have recorded the value of the investment at the put option strike price, or $1.8 million in aggregate. The difference in the aggregate value of the investment, based on the spread between the exercise prices of the put and call options, is $0.6 million. We consider this value to be a Level 3 fair value measurement, as this supplier is a private company, and the value has been determined based on unobservable market data (i.e. the proceeds that we would receive if we exercised our put option in full). (6) Represents upfront loan fees on credit facilities that are expected to be used to partially finance the purchase and installation of scrubbers or refinance the indebtedness on certain vessels. These fees are reclassified as deferred financing fees (net of Debt) when the tranche of the loan to which the vessel relates is drawn. (7) Represents prepaid equity issuance costs related to keeping the ATM Program active.

(4) Other activity for this arrangement represents the non-cash entry to reduce lease liabilities of $0.4 million when these leases were modified in 2021. Secured Bank Debt Each of our secured credit facilities contains financial and restrictive covenants, which require us to, among other things, comply with certain financial tests (described below); deliver quarterly and annual financial statements and annual projections; comply with restrictive covenants, including maintaining adequate insurances; comply with laws (including environmental laws and ERISA); and maintain flag and class of our vessels. Other such covenants may, among other things, restrict consolidations, mergers or sales of our assets; require us to obtain lender approval on changes in our vessel manager; limit our ability to place liens on our assets; limit our ability to incur additional indebtedness; prohibit us from paying dividends if there is a covenant breach under the loan or an event of default has occurred or would occur as a result of payment of such dividend; or prohibit our transactions with affiliates. Furthermore, our debt agreements contain customary events of default, including cross-default provisions, as well as subjective acceleration clauses under which the debt could become due and payable in the event of a material adverse change in the Company’s business. These secured credit facilities may be secured by, among other things: • a first priority mortgage over the relevant collateralized vessels; • a first priority assignment of earnings, insurances and charters from the mortgaged vessels for the specific facility; • a pledge of earnings generated by the mortgaged vessels for the specific facility; and • a pledge of the equity interests of each vessel owning subsidiary under the specific facility. Each of our secured credit facilities are described below. KEXIM Credit Facility In February 2014, we executed a senior secured term loan facility for $429.6 million, with a group of financial institutions led by DNB Bank ASA and Skandinaviska Enskilda Banken AB (publ) and from KEXIM, a statutory juridical entity established under The Export-Import Bank of Korea Act of 1969, as amended, in the Republic of Korea. We refer to this facility as the KEXIM Credit Facility. This KEXIM Credit Facility included commitments from KEXIM of $300.6 million, or the KEXIM Tranche, and a group of financial institutions led by DNB Bank ASA and Skandinaviska Enskilda Banken AB (publ) of $129.0 million, or the Commercial Tranche. Drawdowns under the KEXIM Credit Facility occurred in connection with the delivery of 18 newbuilding vessels as specified in the loan agreement. In addition to KEXIM’s commitment of up to $300.6 million, KEXIM also provided an optional guarantee for a five During the year ended December 31, 2019, the debt on five vessels that were collateralized under this facility were refinanced with a portion of the proceeds from the Hamburg Commercial Bank Credit Facility and the Prudential Credit Facility, as described below. During the year ended December 31, 2020, the debt on twelve vessels that were collateralized under this facility were refinanced with a portion of the proceeds from the BNPP Sinosure Credit Facility, the 2019 DNB/GIEK Credit Facility and the ING Credit Facility, as described below. The amount outstanding relating to this facility was $15.9 million as of December 31, 2020, and we were in compliance with the financial covenants under this facility as of that date. In January 2021, this facility was repaid in full upon the maturity of the Commercial Tranche and refinanced using a portion of the proceeds of the 2021 $21 Million Credit Facility, as described below. ING Credit Facility In June 2015, we executed a senior secured term loan facility with ING Bank N.V., London Branch for a credit facility of up to $52.0 million (the "ING Credit Facility"). In September 2015, we amended and restated the facility to increase the borrowing capacity to $87.0 million, and in March 2016, we amended and restated the facility to further increase the borrowing capacity to $132.5 million. In June 2018, we executed another agreement to further increase the borrowing capacity to $171.2 million. In September 2019, we executed another agreement to further increase the borrowing capacity to partially finance the purchase and installation of scrubbers on seven of the vessels collateralized under this facility. In July and September 2020, we drew down an aggregate of $5.9 million under the scrubber portion of this facility to partially finance the purchase and installation of scrubbers on four MRs and one LR2 that are currently part of this arrangement. The scrubber related borrowings are scheduled to mature upon the maturity dates of the respective vessel tranche of the loan to which the scrubber relates. In May 2020, we executed another agreement to further increase the borrowing capacity to $251.4 million. This upsized portion of this facility of $72.1 million was fully drawn in May 2020, and the proceeds were used to refinance the existing debt on five vessels ( STI Broadway, STI Comandante, STI Brixton, STI Pimlico and STI Finchley ), which were previously financed under the KEXIM Credit Facility. We repaid the outstanding indebtedness of $60.2 million related to these vessels under the KEXIM Credit Facility as part of this transaction. In July 2020, we drew down on the scrubber portion of the facility consisting of (i) $2.2 million related to STI Lombard and STI Osceola and (ii) $1.1 million related to STI Pontiac . In September 2020, we drew down on the scrubber portion of the facility consisting of (i) $1.1 million related to STI Black Hawk which and (ii) $1.5 million related to STI Notting Hill . In January 2021, we drew down $2.1 million from ING Credit Facility to partially finance the purchase and installations of scrubbers on two LR2 product tankers ( STI Grace and STI Jermyn ). The ING Credit Facility was repaid in full during the year ended December 31, 2021 when the amounts borrowed were refinanced with a portion of the proceeds from the 2021 $146.3 Million Lease Financing, the 2021 AVIC Lease Financing, the 2021 CMBFL Lease Financing, the 2021 TSFL Lease Financing, and the 2021 CSSC Lease Financing. These lease financing arrangements are described below. The amount outstanding relating to this facility was $191.3 million as of December 31, 2020, and we were in compliance with the financial covenants under this facility as of that date. 2018 NIBC Credit Facility In June 2018, we executed an agreement with NIBC Bank N.V. for a $35.7 million term loan facility (the "2018 NIBC Credit Facility"). This facility was fully drawn in August 2018, and the proceeds were used to refinance the existing indebtedness related to two MR product tankers ( STI Memphis and STI Soho ). Additionally, in August 2019, we executed an agreement to upsize the existing NIBC Credit Facility by $3.1 million in aggregate, the proceeds of which were used to partially finance the purchase and installation of scrubbers on the two vessels that were collateralized under this facility. In April 2020, we drew down $3.1 million on the scrubber portion of this facility. The 2018 NIBC Credit Facility was repaid in full during the year ended December 31, 2021 when the amounts borrowed were refinanced with a portion of the proceeds from the 2021 AVIC Lease Financing, as described below. The amount outstanding relating to this facility was $31.1 million as of December 31, 2020. We were in compliance with the financial covenants relating to this facility as of that date. Credit Agricole Credit Facility As part of the closing of the four LR1s that were acquired from Navig8 Product Tankers Inc. in June 2017, we assumed the outstanding indebtedness under a senior secured term loan with Credit Agricole (the "Credit Agricole Credit Facility"). STI Excel, STI Excelsior, STI Expedite and STI Exceed are pledged as collateral under this facility. Repayments are being made in equal quarterly installments of $2.1 million in aggregate in accordance with a 15-year repayment profile with a balloon payment due upon maturity, which occurs between November 2022 and February 2023 (depending on the vessel). The facility bears interest at LIBOR plus a margin of 2.75% per annum. Our Credit Agricole Credit Facility includes financial covenants that require us to maintain: • The ratio of net debt to total capitalization no greater than 0.60 to 1.00. • Consolidated tangible net worth of no less than $1.0 billion plus (i) 25% of the cumulative positive net income (on a consolidated basis) for each fiscal quarter commencing on or after January 1, 2016 and (ii) 50% of the net proceeds of new equity issues occurring on or after January 1, 2016. • Minimum liquidity of not less than the greater of $25.0 million or $500,000 per each owned vessel and $250,000 per each time chartered-in vessel. • The aggregate of the fair market value of the vessels provided as collateral under the facility shall at all times be no less than 135% of the then aggregate outstanding principal amount of the loan outstanding under the credit facility. The carrying values of the indebtedness related to this facility (which includes the discount recorded to write the value down to its fair value as part of the purchase price allocation of the acquisition) as of December 31, 2021 and 2020 were $72.8 million and $80.7 million. We were in compliance with the financial covenants relating to this facility as of those dates. ABN AMRO / K-Sure Credit Facility We assumed the outstanding indebtedness on a senior secured credit facility with ABN AMRO Bank N.V. and Korea Trade Insurance Corporation, or K-Sure, as part of the September 2017 acquisition of Navig8 Product Tankers Inc. (the "ABN AMRO / K-Sure Credit Facility"). Two LR1s ( STI Precision and STI Prestige ) are collateralized under this facility and the facility consisted of two separate tranches, a $11.5 million commercial tranche and a $43.8 million K-Sure tranche. The ABN AMRO / K-Sure Credit Facility was repaid in full during the year ended December 31, 2021 when the amounts borrowed were refinanced with a portion of the proceeds from the 2021 $43.6 Million Credit Facility, as described below. Additionally, we had an aggregate of $0.5 million on deposit in a debt service reserve account in accordance with the terms and conditions of this facility. The funds deposited in this account were not freely available and were released upon the final repayment. The balance in this account was previously recorded as non-current Restricted Cash on our consolidated balance sheet as of December 31, 2020 The carrying value of the indebtedness related to this facility (which includes the discount recorded to write the value down to its fair value as part of the purchase price allocation of the acquisition) as of December 31, 2020 was $40.6 million, and we were in compliance with the financial covenants relating to this facility as of that date. Citibank / K-Sure Credit Facility We assumed the outstanding indebtedness under a senior secured credit facility with Citibank N.A., London Branch, Caixabank, S.A., and K-Sure, as part of the September 2017 acquisition of Navig8 Product Tankers Inc. (the "Citibank / K-Sure Credit Facility"). Four LR1s ( STI Excellence , STI Executive , STI Experience , and STI Express ) are collateralized under this facility. The facility consists of two separate tranches, a $25.1 million commercial tranche and a $91.2 million K-Sure tranche, which represents the amounts assumed from Navig8 Product Tankers Inc. ("NPTI"). The commercial tranche bears interest at LIBOR plus 2.50% per annum, and the K-Sure tranche bears interest at LIBOR plus 1.60% per annum. Repayments on the K-Sure tranche are being made in equal quarterly installments of $2.1 million in accordance with a 12-year repayment profile from the date of delivery from the shipyard, with a balloon payment due upon maturity, and the commercial tranche is scheduled to be repaid via a balloon payment upon maturity which occurs between March and May 2022 (depending on the vessel). The K-Sure tranche fully matures between March and May 2028 (depending on the vessel), and K-Sure has an option to require repayment upon the maturity of the commercial tranche if the commercial tranche is not refinanced by its maturity dates. Our Citibank / K-Sure Credit Facility includes financial covenants that require us to maintain: • The ratio of net debt to total capitalization no greater than 0.60 to 1.00. • Consolidated tangible net worth of no less than $1.0 billion plus (i) 25% of the cumulative positive net income (on a consolidated basis) for each fiscal quarter commencing on or after January 1, 2016 and (ii) 50% of the net proceeds of new equity issues occurring on or after January 1, 2016. • Minimum liquidity of not less than the greater of $25.0 million or $500,000 per each owned vessel and $250,000 per each time chartered-in vessel. • The aggregate of the fair market value of the vessels provided as collateral under the facility shall at all times be no less than 135% of the then aggregate outstanding principal amount of the loans (less any amounts held in a debt service reserve account as described below) under the credit facility. Additionally, we have an aggregate of $4.0 million on deposit in a debt service reserve account as of December 31, 2021 in accordance with the terms and conditions of this facility. The funds deposited in this account are not freely available and will be released upon maturity. The balance in this account has been recorded as current Restricted Cash on our consolidated balance sheet as of December 31, 2021 and as non-current Restricted Cash as of December 31, 2020. The carrying values of the indebtedness related to this facility (which includes the discount recorded to write the value down to its fair value as part of the purchase price allocation of the acquisition) as of December 31, 2021 and 2020 were $77.8 million and $84.5 million, respectively. We were in compliance with the financial covenants relating to this facility as of those dates. ABN AMRO / SEB Credit Facility In June 2018, we executed a senior secured term loan facility with ABN AMRO Bank N.V. and Skandinaviska Enskilda Banken AB for up to $120.6 million (the "ABN AMRO / SEB Credit Facility"). This loan was fully drawn in June 2018, and the proceeds were used to refinance the existing indebtedness of $87.6 million under our K-Sure Credit Facility relating to five vessels consisting of one Handymax product tanker ( STI Hammersmith ), one MR product tanker ( STI Westminster ), and three LR2 product tankers ( STI Connaught, STI Winnie and STI Lauren ). Additionally, in September 2019, we executed an agreement with the lenders under this facility to upsize the credit facility by up to $6.3 million, which was fully drawn in 2020 with the proceeds used to partially finance the purchase and installation of scrubbers on four of the vessels that were collateralized under this facility. The amount outstanding related to this facility as of December 31, 2020 was $97.9 million. We were in compliance with the financial covenants relating to this facility as of that date. The ABN AMRO / SEB Credit Facility was repaid in full during the year ended December 31, 2021 when the amounts borrowed were refinanced with portions of the proceeds from the 2021 CMBFL Lease Financing and the 2021 $146.3 Million Credit Facility, as described below.

The loan is comprised of two facilities: (i) an ECA facility of $47.2 million (which is comprised of a $41.6 million tranche which is guaranteed by GIEK, or the “GIEK Tranche”, and a $5.6 million commercial tranche or the “Commercial Bank Tranche”) and (ii) a commercial facility of $8.3 million, or the “Commercial Facility." These facilities are collectively referred to as the 2019 DNB/GIEK Credit Facility. In March 2020, we drew $31.9 million from this facility to refinance the existing debt on an LR2, STI Sloane , that was previously financed under the KEXIM Credit Facility. We repaid the outstanding indebtedness of $17.4 million related to this vessel on the KEXIM Credit Facility as part of this transaction.

BNPP Sinosure Credit Facility In December 2019, we executed a senior secured term loan facility with BNP Paribas and Skandinaviska Enskilda Banken AB for up to $134.1 million. This loan is split into two facilities, (i) a commercial facility for up to $67.0 million (the "Commercial Facility"), and (ii) a Sinosure facility for up to $67.0 million (the "Sinosure Facility"), which was funded by the lenders under the commercial facility and insured by the China Export & Credit Insurance Corporation ("Sinosure"). These facilities are collectively referred to as the BNPP Sinosure Credit Facility. In March 2020, we drew $42.1 million from this facility to partially finance the purchase and installation of scrubbers on 22 vessels.

Trafigura Transaction As described in Note 6, in September 2019, we acquired the leasehold interests in 19 product tankers (four of which were under construction) as part of the Trafigura Transaction. The consideration exchanged consisted of: • For the 15 delivered vessels, the assumption of the obligations under the Agreements of $531.5 million and the issuance of 3,981,619 shares of common stock at $29.00 per share to a nominee of Trafigura with an aggregate market value of $115.5 million. • For the four vessels that were under construction, the assumption of the commitments on the Agreements of $138.8 million and the issuance 591,254 shares of common stock at $29.00 per share to a nominee of Trafigura with an aggregate market value of $17.1 million.

At the Market Share Issuance Program In November 2019, we entered into an “at the market” offering program (the “ATM Program”) pursuant to which we may sell up to $100 million of our common shares, par value $0.01 per share. As part of the ATM Program, we entered into an equity distribution agreement dated November 7, 2019 (the “Sales Agreement”), with BTIG, LLC, as sales agent (the “Agent”). In accordance with the terms of the Sales Agreement, we may offer and sell our common shares from time to time through the Agent by means of ordinary brokers’ transactions on the NYSE at market prices, in block transactions, or as otherwise agreed upon by the Agent and us. We intend to use the net proceeds from any sales under the ATM Program for general corporate and working capital purposes. During the year ended December 31, 2020, we sold an aggregate of 137,067 of our common shares at an average price of $18.79 per share for aggregate net proceeds of $2.6 million. No shares were sold during the year ended December 31, 2021. There is $97.4 million of remaining availability under the ATM Program as of December 31, 2021. 2013 Equity Incentive Plan In April 2013, we adopted an equity incentive plan, which was amended in March 2014 and which we refer to as the 2013 Equity Incentive Plan, under which directors, officers, employees, consultants and service providers of us and our subsidiaries and affiliates are eligible to receive incentive stock options and non-qualified stock options, stock appreciation rights, restricted stock, restricted stock units and unrestricted common stock. We initially reserved a total of 500,000 common shares for issuance under the 2013 Equity Incentive Plan which was increased by an aggregate of 4,342,783 common shares through December 31, 2018 and subsequently revised as follows: • In February 2019, we reserved an additional 86,977 common shares, par value $0.01 per share, for issuance pursuant to the 2013 Equity Incentive Plan. All other terms of the 2013 Equity Incentive Plan remained unchanged. • In July 2019, we reserved an additional 134,893 common shares, par value $0.01 per share, for issuance pursuant to the 2013 Equity Incentive Plan. All other terms of the 2013 Equity Incentive Plan remained unchanged. • In December 2019, we reserved an additional 529,624 common shares, par value $0.01 per share, for issuance pursuant to the 2013 Equity Incentive Plan. All other terms of the 2013 Equity Incentive Plan remained unchanged. • In June 2020, we reserved an additional 362,766 common shares, par value $0.01 per share, for issuance pursuant to the 2013 Equity Incentive Plan. All other terms of the 2013 Equity Incentive Plan remained unchanged. • In December 2020, we reserved an additional 367,603 common shares, par value $0.01 per share, for issuance pursuant to the 2013 Equity Incentive Plan. All other terms of the 2013 Equity Incentive Plan remained unchanged. • In June 2021, we reserved an additional 386,883 common shares, par value $0.01 per share, for issuance pursuant to the 2013 Equity Incentive Plan. All other terms of the 2013 Equity Incentive Plan remained unchanged. • In October 2021, we reserved an additional 693,864 common shares, par value $0.01 per share, for issuance pursuant to the 2013 Equity Incentive Plan. All other terms of the 2013 Equity Incentive Plan remained unchanged. Under the terms of the 2013 Equity Incentive Plan, stock options and stock appreciation rights granted under the 2013 Equity Incentive Plan will have an exercise price equal to the fair market value of a common share on the date of grant, unless otherwise determined by the plan administrator, but in no event will the exercise price be less than the fair market value of a common share on the date of grant. Options and stock appreciation rights will be exercisable at times and under conditions as determined by the plan administrator, but in no event will they be exercisable later than ten years from the date of grant. The plan administrator may grant shares of restricted stock and awards of restricted stock units subject to vesting, forfeiture and other terms and conditions as determined by the plan administrator. Following the vesting of a restricted stock unit, the award recipient will be paid an amount equal to the number of vested restricted stock units multiplied by the fair market value of a common share on the date of vesting, which payment may be paid in the form of cash or common shares or a combination of both, as determined by the plan administrator. The plan administrator may grant dividend equivalents with respect to grants of restricted stock units. Adjustments may be made to outstanding awards in the event of a corporate transaction or change in capitalization or other extraordinary event. In the event of a “change in control” (as defined in the 2013 Equity Incentive Plan), unless otherwise provided by the plan administrator in an award agreement, awards then outstanding will become fully vested and exercisable in full. Our Board of Directors may amend or terminate the 2013 Equity Incentive Plan and may amend outstanding awards, provided that no such amendment or termination may be made that would materially impair any rights, or materially increase any obligations, of a grantee under an outstanding award. Shareholder approval of plan amendments will be required under certain circumstances. Unless terminated earlier by our board of directors, the 2013 Equity Incentive Plan will expire ten years from the date the plan was adopted. The following paragraphs summarize our grants of restricted stock during the years ended December 31, 2021, 2020, and 2019. The vesting periods of these grants are determined by the plan administrator and generally range from one five In June 2019, we issued 112,750 shares of restricted stock to our employees and 107,500 to SSH employees for no cash consideration.

Related Party [Abstract]
Related party transactions	Related party transactions Our vessels are commercially managed by SCM and technically managed by SSM pursuant to the terms and conditions set forth under a revised master agreement which was effective as from January 1, 2018 (the "Revised Master Agreement"). The Revised Master Agreement may be terminated by either party upon 24 months' notice, unless terminated earlier in accordance with the provisions of the Revised Master Agreement. In the event of the sale of one or more vessels, a notice period of three months and a payment equal to three months of management fees will apply, provided that the termination does not amount to a change in control, including a sale of all or substantially all of our vessels, in which case a payment equal to 24 months of management fees will apply. SCM and SSM are related parties of ours. We expect that any additional vessels that we may acquire in the future will also be managed under the Revised Master Agreement or on substantially similar terms. Transactions with entities controlled by the Lolli-Ghetti family (herein referred to as related parties) in the consolidated statements of income or loss and balance sheets are as follows: For the year ended December 31, In thousands of U.S. dollars 2021 2020 2019 Pool revenue (1) Scorpio MR Pool Limited $ 256,874 $ 340,937 $ 261,727 Scorpio LR2 Pool Limited 180,912 369,476 260,893 Scorpio Handymax Tanker Pool Limited 50,143 105,355 103,150 Scorpio LR1 Pool Limited 47,053 87,028 66,009 Voyage revenue (2) — 2,334 — Voyage expenses (3) (1,461) (3,507) (2,414) Vessel operating costs (4) (35,427) (33,896) (31,732) Administrative expenses (5) (13,557) (13,876) (12,975) (1) These transactions relate to revenue earned in the Scorpio Pools. The Scorpio Pools are related parties. When our vessels are in the Scorpio Pools, SCM, the pool manager, charges fees of $300 per vessel per day with respect to our LR1/Panamax and Aframax vessels, $250 per vessel per day with respect to our LR2 vessels, and $325 per vessel per day with respect to each of our Handymax and MR vessels, plus a commission of 1.50% on gross revenue per charter fixture. These are the same fees that SCM charges other vessels in these pools, including third party vessels. In September 2018, we entered into an agreement with SCM whereby SCM reimbursed a portion of the commissions that SCM charges the Company’s vessels to effectively reduce such to 0.85% of gross revenue per charter fixture, effective from September 1, 2018 and ending on June 1, 2019. (2) These transactions relate to revenue earned in the spot market on voyages chartered through SSH, a related party. (3) Related party expenditures included within voyage expenses in the consolidated statements of income or loss consist of the following: • Expenses due to SCM, a related party, for commissions related to the commercial management services provided by SCM under the commercial management agreement for vessels that are not in one of the Scorpio Pools. SCM’s services include securing employment, in the spot market and on time charters, for our vessels. When not in one of the Scorpio Pools, each vessel pays (i) flat fees of $250 per day for LR1/Panamax and LR2/Aframax vessels and $300 per day for Handymax and MR vessels and (ii) commissions of 1.25% of their gross revenue per charter fixture. These expenses are included in voyage expenses in the consolidated statements of income or loss. In September 2018, we entered into an agreement with SCM whereby SCM reimbursed a portion of the commissions that SCM charges the Company’s vessels to effectively reduce such to 0.85% of gross revenue per charter fixture, effective from September 1, 2018 and ending on June 1, 2019. • Bunkers of $2.6 million, $3.6 million, and $0.8 million were purchased from a related party bunker provider during the years ended December 31, 2021, 2020, and 2019, respectively. These bunkers were purchased when our vessels were operating in the spot market, outside of the Scorpio Pools. Approximately $1.4 million, $2.9 million, and $0.3 million, respectively, of these purchases were consumed during the spot market voyages, and the remaining unconsumed portion was considered a working capital contribution to the pool (see below for a description on the accounting for working capital contributions to the Scorpio Pools) when the vessels re-joined the pools during the years ended December 31, 2021 and 2020, respectively. • Voyage expenses of $19,175, $4,925 and $4,357 charged by a related party port agent during the years ended December 31, 2021, 2020. and 2019 respectively. SSH has a majority equity interest in a port agent that provides supply and logistical services for vessels operating in its regions. (4) Related party expenditures included within vessel operating costs in the consolidated statements of income or loss consist of the following: • Technical management fees of $32.7 million, $31.9 million, and $30.0 million charged by SSM, a related party, during the years ended December 31, 2021, 2020 and 2019 respectively. SSM’s services include day-to-day vessel operations, performing general maintenance, monitoring regulatory and classification society compliance, customer vetting procedures, supervising the maintenance and general efficiency of vessels, arranging the hiring of qualified officers and crew, arranging and supervising drydocking and repairs, purchasing supplies, spare parts and new equipment for vessels, appointing supervisors and technical consultants, and providing technical support. SSM administers the payment of salaries to our crew on our behalf. The crew wages that were administered by SSM (and disbursed through related party subcontractors of SSM) were $152.0 million, $146.0 million, and $138.9 million during the years ended December 31, 2021, 2020, and 2019 respectively. SSM's annual technical management fee is a fixed fee of $175,000 per vessel plus certain itemized expenses pursuant to the technical management agreement. • Vessel operating expenses of $2.7 million, $2.0 million, and $1.7 million charged by a related party port agent during the years ended December 31, 2021, 2020 and 2019, respectively. SSH has a majority equity interest in a port agent that provides supply and logistical services for vessels operating in its regions. (5) We have an Amended Administrative Services Agreement with SSH for the provision of administrative staff and office space, and administrative services, including accounting, legal compliance, financial and information technology services. SSH also administers the payroll for certain of our employees. SSH is a related party to us. The services provided to us by SSH may be sub-contracted to other entities within Scorpio. The expenses incurred under this agreement were recorded in general and administrative expenses in the consolidated statement of income or loss and were as follows: • The expense for the year ended December 31, 2021 of $13.6 million included (i) administrative fees of $12.2 million charged by SSH, (ii) restricted stock amortization of $1.3 million, which relates to the issuance of an aggregate of 315,950 shares of restricted stock to SSH employees for no cash consideration pursuant to the 2013 Equity Incentive Plan, and (iii) the reimbursement of expenses of $51,962 to SSH and $14,726 to SCM. • The expense for the year ended December 31, 2020 of $13.9 million included (i) administrative fees of $12.6 million charged by SSH, (ii) restricted stock amortization of $1.2 million, which relates to the issuance of an aggregate of 315,950 shares of restricted stock to SSH employees for no cash consideration pursuant to the 2013 Equity Incentive Plan and (iii) the reimbursement of expenses of $19,772 to SSH and $45,539 to SCM. • The expense for the year ended December 31, 2019 of $13.0 million included (i) administrative fees of $11.4 million charged by SSH, (ii) restricted stock amortization of $1.1 million, which relates to the issuance of an aggregate of 221,900 shares of restricted stock to SSH employees for no cash consideration pursuant to the 2013 Equity Incentive Plan and (iii) the reimbursement of expenses of $0.2 million to SSH and $0.2 million to SCM. We had the following balances with related parties, which have been included in the consolidated balance sheets: As of December 31, In thousands of U.S. dollars 2021 2020 Assets: Accounts receivable (due from the Scorpio Pools) (1) $ 36,216 $ 26,413 Accounts receivable and prepaid expenses (SSM) (2) 3,426 4,259 Other assets (pool working capital contributions) (3) 73,161 73,161 Liabilities: Accounts payable and accrued expenses (SSM) 9,844 935 Accounts payable and accrued expenses (owed to the Scorpio Pools) 2,548 945 Accounts payable and accrued expenses (SSH) 1,888 404 Accounts payable and accrued expenses (related party port agent) 674 355 Accounts payable and accrued expenses (SCM) 25 58 (1) Accounts receivable due from the Scorpio Pools relate to hire receivables for revenues earned and receivables from working capital contributions. The amounts as of December 31, 2020 included $1.1 million of working capital contributions made on behalf of our vessels to the Scorpio Pools. Upon entrance into such pools, all vessels are required to make working capital contributions of both cash and bunkers. Additional working capital contributions can be made from time to time based on the operating needs of the pools. These amounts are accounted for and repaid as follows: • For vessels in the Scorpio LR2 Pool, Scorpio LR1 Pool, Scorpio MR Pool and Scorpio Handymax Tanker Pool, the initial contribution amount is repaid, without interest, upon a vessel’s exit from the pool no later than six months after the exit date. Bunkers on board a vessel exiting the pool are credited against such repayment at the actual invoice price of the bunkers. For all owned or lease financed vessels we assume that these contributions will not be repaid within 12 months and are thus classified as non-current within other assets on the consolidated balance sheets. • For time or bareboat chartered-in vessels we classify the initial contributions as current (within accounts receivable) or non-current (within other assets) according to the expiration of the contract. Any additional working capital contributions are repaid when sufficient net revenues become available to cover such amounts. (2) Accounts receivable and prepaid expenses from SSM primarily relate to advances made for vessel operating expenses (such as crew wages) that will either be reimbursed or applied against future costs. (3) Represents the non-current portion of working capital receivables as described above. Private Placement In September 2019, we closed on a private placement with SSH for $15.0 million, in exchange for an aggregate of 517,241 of our common shares at $29.00 per share, as described in Note 14. Other transactions Starting in October 2019, we provided guarantees in respect of the payment obligations of a related party bunker provider (who is engaged in the procurement of bunkers on behalf of the Company and the Scorpio Pools) toward its physical suppliers. These guarantee agreements expired during the year ended December 31, 2021 and no amounts were paid to this provider under these guarantees during the years ended December 31, 2021 and 2020. As described in Note 8, in August 2021, we acquired a minority interest in a portfolio of nine product tankers, consisting of five dual-fuel MR methanol tankers (built between 2016 and 2021) along with four ice class 1A LR1 product tankers. Two of the LR1 tankers that are part of this joint venture are commercially and technically managed by SCM and SSM, respectively. Key management remuneration The table below shows key management remuneration for the years ended December 31, 2021, 2020 and 2019: For the year ended December 31, In thousands of U.S. dollars 2021 2020 2019 Short-term employee benefits (salaries) $ 5,488 $ 10,989 $ 10,821 Share-based compensation (1) 17,476 22,217 21,712 Total $ 22,964 $ 33,206 $ 32,533 (1) Represents the amortization of restricted stock issued under our 2013 Equity Incentive Plan as described in Note 14. For the purpose of the table above, key management are those persons who have authority and responsibility for making strategic decisions, and managing operating, financial and legal activities. We have entered into employment agreements with the majority of our executives. These employment agreements remain in effect until terminated in accordance with their terms upon not less than between 24 months' and 36 months' prior written notice, depending on the terms of the employment agreement applicable to each executive. Pursuant to the terms of their respective employment agreements, our executives are prohibited from disclosing or unlawfully using any of our material confidential information. Upon a change in control of us, the annual bonus provided under the employment agreement becomes a fixed bonus of between 150% and 250% of the executive’s base salary, and the executive may receive an assurance bonus equal to the fixed bonus, depending on the terms of the employment agreement applicable to each executive. Any such executive may be entitled to receive upon termination an assurance bonus equal to such fixed bonus and an immediate lump-sum payment in an amount equal to three times the sum of the executive’s then current base salary and the assurance bonus, and he will continue to receive all salary, compensation payments and benefits, including additional bonus payments, otherwise due to him, to the extent permitted by applicable law, for the remaining balance of his then-existing employment period. If an executive’s employment is terminated for cause or voluntarily by the employee, he shall not be entitled to any salary, benefits or reimbursements beyond those accrued through the date of his termination, unless he voluntarily terminated his employment in connection with certain conditions. Those conditions include a change in control combined with a significant geographic relocation of his office, a material diminution of his duties and responsibilities, and other conditions identified in the employment agreement. There are no material post-employment benefits for our executive officers or directors. By law, our employees in Monaco are entitled to a one-time payment of up to two months salary upon retirement if they meet certain minimum service requirements.

Vessel revenue

Analysis of income and expense [abstract]
Vessel revenue	Vessel revenue During the years ended December 31 2019, we had five vessels that earned revenue through long-term time-charter contracts (with initial terms of one year or greater), respectively. There were no vessels that earned revenue through long-term time-charter contracts during the years ended December 31, 2021 and 2020. The remaining vessels earned revenue from the Scorpio Pools or in the spot market. The following table sets forth our revenue, by employment type, for these periods: For the year ended December 31, In thousands of U.S. dollars 2021 2020 2019 Pool revenue $ 534,982 $ 902,796 $ 691,886 Time charter revenue — — 2,551 Voyage revenue (spot market) 5,804 13,096 9,888 $ 540,786 $ 915,892 $ 704,325 IFRS 16 Lease Revenue In accordance with IFRS 16 - Leases, we are required to identify the lease and non-lease components of revenue and account for each component in accordance with the applicable accounting standard. In time charter-out or pool arrangements, we have determined that the lease component is the vessel and the non-lease component is the technical management services provided to operate the vessel. Each component is quantified on the basis of the relative stand-alone price of each lease component and on the aggregate stand-alone price of the non-lease components. These components will be accounted for as follows: • All fixed lease revenue earned under these time charter-out arrangements is recognized on a straight-line basis over the term of the lease. • Lease revenue earned under our pool arrangements is recognized as it is earned, since it is 100% variable. • The non-lease component is accounted for as services revenue under IFRS 15. This revenue is recognized “over time” as the customer (i.e. the pool or the charterer) is simultaneously receiving and consuming the benefits of the service. The following table summarizes the lease and non-lease components of revenue from time charter-out and pool revenue during the years ended December 31, 2021, 2020 and 2019. These figures are not readily quantifiable as the Company's contracts (with the Scorpio pools or under time charter-out arrangements) do not separate these components. The Company does not view its pool and time charter-out revenue as two separate streams of revenue. Nevertheless, we have estimated these amounts by reference to (i) third party, published time charter rates for the lease component, and (ii) an approximation of the fair market value of vessel operating expenses for the non-lease component. For the year ended December 31, In thousands of U.S. dollars 2021 2020 2019 Lease component of revenue from time charter-out and pool revenue $ 280,633 $ 548,988 $ 428,781 Non-lease component of revenue from time charter-out and pool revenue 254,349 353,808 265,656 $ 534,982 $ 902,796 $ 694,437 The following table summarizes the terms of our time chartered-out vessels that were in place during the years ended December 31, 2019.

General and administrative expenses	General and administrative expenses General and administrative expenses primarily represent employee benefit expenses, professional fees and administrative fees payable to SSH under our administrative services agreement (as described in Note 15). Employee benefit expenses (excluding crew) consist of: For the year ended December 31, In thousands of U.S. dollars 2021 2020 2019 Short term employee benefits (salaries) $ 10,841 $ 18,099 $ 16,776 Share based compensation (see Note 14) 22,931 28,506 27,421 $ 33,772 $ 46,605 $ 44,197 There are no material post-employment benefits for our executive officers or directors.

Financial expenses

Analysis of income and expense [abstract]
Financial expenses	Financial expenses The following table sets forth the components of our financial expenses for the years ended December 31, 2021, 2020 and 2019: For the year ended December 31, In thousands of U.S. dollars 2021 2020 2019 Interest expense on debt, net of capitalized interest (1) $ 115,983 $ 132,423 $ 162,738 Accretion of convertible notes (as described in Note 12) 13,265 8,413 11,375 Amortization of deferred financing fees 7,570 6,657 7,041 Loss on extinguishment of debt and write-off of deferred financing fees (2) 3,604 4,056 1,466 Accretion of premiums and discounts on debt (3) 3,682 3,422 3,615 Total financial expenses $ 144,104 $ 154,971 $ 186,235 (1) The decrease in interest expense, net of capitalized interest during the year ended December 31, 2021 is primarily attributable to lower average LIBOR rates compared to the year ended December 31, 2020. As a result of the onset of the COVID-19 pandemic in March 2020, LIBOR rates decreased significantly during the year ended December 31, 2020. Given the timing of when interest rates are fixed on our variable rate borrowings, this decrease primarily impacted our interest expense in the second half of that year and throughout 2021. The average carrying value of our debt was relatively unchanged at $3.14 billion as of December 31, 2021 compared to $3.13 billion as of December 31, 2020. The decrease in interest expense during the year ended December 31, 2020 is primarily attributable to lower LIBOR rates. As a result of the COVID-19 pandemic, LIBOR rates decreased significantly during the year ended December 31, 2020. Additionally, we were able to lower the weighted average margin on our variable rate debt through various refinancing initiatives commencing in the fourth quarter of 2019 and throughout 2020. The combination resulted in lower interest expense for the year ended December 31, 2020 compared to December 31, 2019 despite the increase in the average carrying value of our debt to $3.13 billion from $2.91 billion as of December 31, 2020 and 2019, respectively.

Accordingly, interest expense, deferred financing amortization, and the potentially dilutive securities relating to the conversion of the Convertible Notes due 2022 and Convertible Notes due 2025 (representing 7,324,132 shares of common stock for the year ended December 31, 2021,) along with the potentially dilutive impact of 2,997,992 unvested shares of restricted stock were excluded from the computation of diluted loss per share for the year ended December 31, 2021. During the year ended December 31, 2020, the inclusion of potentially dilutive shares relating to our Convertible Notes due 2022 (representing an aggregate of 4,004,702 shares of common stock) were excluded from the computation of diluted earnings per share because their effect under the if-converted method would have been anti-dilutive.

Financial Instruments [Abstract]
Financial instruments - financial and other risks	Financial instruments - financial and other risks Funding and capital risk management We manage our funding and capital resources to ensure our ability to continue as a going concern while maximizing the return to the shareholder through optimization of the debt and equity balance. IFRS 13 requires classifications of fair value measures into Levels 1, 2 and 3. Level 1 fair value measurements are those derived from quoted prices (unadjusted) 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). 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). The fair values and carrying values of our financial instruments at December 31, 2021 and 2020, respectively, are shown in the table below. Categories of Financial Instruments As of December 31, 2021 As of December 31, 2020 Amounts in thousands of U.S. dollars Fair value Carrying Value Fair value Carrying Value Financial assets Cash and cash equivalents (1) $ 230,415 $ 230,415 $ 187,511 $ 187,511 Restricted cash (2) 4,791 4,791 5,293 5,293 Accounts receivable (3) 38,069 38,069 33,017 33,017 Investment in BWTS (4) 1,751 1,751 1,751 1,751 Working capital contributions to Scorpio Pools (5) 73,161 73,161 73,161 73,161 Seller's credit on sale leaseback vessels (6) 10,793 10,793 10,192 10,192 Financial liabilities Accounts payable (7) $ 35,080 $ 35,080 $ 12,863 $ 12,863 Accrued expenses (7) 24,906 24,906 32,193 32,193 Secured bank loans (8) 566,310 566,310 976,505 976,505 Sale and leaseback liability (9) 1,648,993 1,639,991 1,290,390 1,271,449 IFRS 16 - lease liability (10) 575,834 575,377 634,707 632,473 Unsecured Senior Notes Due 2025 (11) 69,366 70,209 28,774 28,100 Convertible Notes due 2022 (12) 69,059 69,695 145,647 151,229 Convertible Notes due 2025 (12) 195,438 208,133 — — (1) Cash and cash equivalents are considered Level 1 items as they represent liquid assets with short-term maturities. (2) Restricted cash are considered Level 1 items due to the liquid nature of these assets. (3) We consider that the carrying amount of accounts receivable approximate their fair value due to the relative short maturity of these instruments. (4) We consider the fair value of our minority interest in our BWTS supplier (as described in Note 8) to be a Level 3 fair value measurement, as this supplier is a private company and the value has been determined based on unobservable market data (i.e. the proceeds that we would receive if we exercised the put option set forth in the agreement in full). Moreover, we consider that its carrying value approximates fair value given that the value of this investment is contractually limited to the strike prices set forth in the put and call options prescribed in the agreement and the difference between the two prices is not significant. The difference in the aggregate value of the investment, based on the spread between the exercise prices of the put and call options is $0.6 million. (5) Non-current working capital contributions to the Scorpio Pools are repaid, without interest, upon a vessel’s exit from the pool. For all owned vessels, we assume that these contributions will not be repaid within 12 months and are thus classified as non-current within Other Assets on the consolidated balance sheets. We consider that their carrying values approximate fair value given that the amounts due are contractually fixed based on the terms of each pool agreement. (6) The seller's credit on lease financed vessels represents the present value of the deposits of $4.35 million per vessel ($13.1 million in aggregate) that was retained by the buyer as part of the sale and operating leasebacks of STI Beryl , STI Le Rocher and STI Larvotto . This deposit will either be applied to the purchase price of the vessel if a purchase option is exercised or refunded to us at the expiration of the agreement. This deposit has been recorded as a financial asset measured at amortized cost. The present value of this deposit has been calculated based on the interest rate that is implied in the lease, and the carrying value will accrete over the life of the lease using the effective interest method, through interest income, until expiration. We consider that its carrying value approximates fair value given that its value is contractually fixed based on the terms of each lease. (7) We consider that the carrying amounts of accounts payable and accrued expenses approximate the fair value due to the relative short maturity of these instruments. (8) The carrying value of our secured bank loans are measured at amortized cost using the effective interest method. We consider that their carrying value approximates fair value because the interest rates on these instruments change with, or approximate, market interest rates and the credit risk of the Company has remained stable. Accordingly, we consider their fair value to be a Level 2 measurement. These amounts are shown net of $6.4 million and $12.3 million of unamortized deferred financing fees as of December 31, 2021 and 2020, respectively. (9) The carrying value of our obligations due under sale and leaseback arrangements are measured at amortized cost using the effective interest method. With the exception of three fixed rate sale and leaseback arrangements, we consider that their carrying value approximates fair value because the interest rates on these instruments change with, or approximate, market interest rates and the credit risk of the Company has remained stable. The fair value of leases with fixed payments are measured at the net discounted value of the remaining minimum lease payments using our incremental borrowing rate at December 31, 2021. Accordingly, we consider their fair value to be a Level 2 measurement. These amounts are shown net of $13.1 million and $8.7 million of unamortized deferred financing fees as of December 31, 2021 and 2020, respectively. (10) The carrying value of our lease obligations that are being accounted for under IFRS 16 are measured at the present value of the minimum lease payments under each contract. These leases are mainly comprised of the leases acquired as part of the Trafigura Transaction. We consider that their carrying value approximates fair value because the interest rates on these leases change with, or approximate, market interest rates and the credit risk of the Company has remained stable. The fair value of leases with fixed payments are measured at the net discounted value of the remaining minimum lease payments using our incremental borrowing rate at December 31, 2021 and 2020. Accordingly, we consider their fair value to be a Level 2 measurement. (11) The carrying value of our Senior Notes Due 2025 is measured at amortized cost using the effective interest method. The carrying value of our Senior Notes Due 2025 shown in the table above is their face value. The Senior Notes due 2025 are shown net of $2.3 million of deferred financing fees and $0.2 million of unamortized discount on our consolidated balance sheet as of December 31, 2021. The Senior Notes due 2025 are shown net of $1.4 million of unamortized deferred financing fees on our consolidated balance sheet as of December 31, 2020. Our Senior Notes Due 2025 are quoted on the NYSE under the symbol 'SBBA'. We consider their fair value to be a Level 1 measurement due to their quotation on an active exchange. (12) The carrying values of our Convertible Notes due 2022 and 2025 shown in the table above are their face value. The liability components of the Convertible Notes due 2022 and 2025 have been recorded within Long-term debt on the consolidated balance sheet as of December 31, 2021. The equity components of the Convertible Notes due 2022 and 2025 have been recorded within Additional paid-in capital on the consolidated balance sheet as of December 31, 2021. These instruments are quoted in inactive markets and are valued based on their quoted prices on the recent trading activity. Accordingly, we consider their fair value to be a Level 2 measurement. Financial risk management objectives We identify and evaluate significant risks on an ongoing basis with the objective of managing the sensitivity of our results and financial position to those risks. These risks include market risk, credit risk, liquidity risk and foreign exchange risk. The use of financial derivatives is governed by our policies as approved by the Board of Directors. Market risk Our activities expose us to the risks inherent with the tanker industry, which has historically been volatile, and financial risks of changes in interest rates. Spot market rate risk The cyclical nature of the tanker industry causes significant increases or decreases in the revenue that we earn from our vessels, particularly those vessels that operate in the spot market or participate in pools that are concentrated in the spot market such as the Scorpio Pools. Additionally, we have the ability to remove our vessels from the pools on relatively short notice if attractive time charter opportunities arise. A $1,000 per day increase or decrease in spot rates for all of our vessel classes would have increased or decreased our operating income by $46.9 million, $46.2 million and $41.7 million for the years ended December 31, 2021, 2020, and 2019, respectively. Interest rate risk The sensitivity analyses below have been determined based on the exposure to interest rates for non-derivative instruments at the balance sheet date. If interest rates had been 1% higher/lower and all other variables were held constant, our net loss for the year ended December 31, 2021 would have decreased/increased by $26.5 million. This is mainly attributable to our exposure to interest rate movements on our variable interest rate credit facilities, lease financing arrangements and leases being accounted for under IFRS 16 as described in Notes 6 and 12. If interest rates had been 1% higher/lower and all other variables were held constant, our net income for the year ended December 31, 2020 would have decreased/increased by $26.7 million. This is mainly attributable to our exposure to interest rate movements on our variable interest rate credit facilities, lease financing arrangements and leases being accounted for under IFRS 16 as described in Notes 6 and 12. If interest rates had been 1% higher/lower and all other variables were held constant, our net income for the year ended December 31, 2019 would have decreased/increased by $23.1 million. This is mainly attributable to our exposure to interest rate movements on our variable interest rate credit facilities and lease financing arrangements that were in place during that year. Credit risk Credit risk is the potential exposure of loss in the event of non-performance by customers and derivative instrument counterparties. We only place cash deposits with major banks covered with strong and acceptable credit ratings. Accounts receivable are generally not collateralized; however, we believe that the credit risk is partially offset by the creditworthiness of our counterparties including the commercial manager. We did not experience any credit losses on our accounts receivables portfolio in the years ended December 31, 2021, 2020, and 2019. The carrying amount of financial assets recognized on our consolidated financial statements represents the maximum exposure to credit risk without taking into account the value of any collateral obtained. We did not experience any impairment losses on financial assets in the years ended December 31, 2021, 2020, and 2019. We monitor exposure to credit risk, and believe that there is no substantial credit risk arising from counterparties. Liquidity risk Liquidity risk is the risk that an entity will encounter difficulty in raising funds to meet commitments associated with financial instruments. We manage liquidity risk by maintaining adequate reserves and borrowing facilities and by continuously monitoring forecast and actual cash flows. Liquidity risks can manifest themselves when economic conditions deteriorate or when we have significant maturities of our financial instruments. Financing risks As of December 31, 2021, the financings for four vessels under our Citibank / K-Sure Credit Facility for $76.8 million in aggregate and the financing for one vessel under our Credit Agricole Credit Facility for $16.5 million are scheduled to mature within 2022. Additionally, the financings for three vessels under our Credit Agricole Credit Facility for $49.1 million in aggregate are scheduled to mature during the first quarter of 2023. As described in Note 23, in January 2022, we entered into agreements to sell all of these vessels within 12 months from the date of these financial statements. Furthermore, our Convertible Notes Due 2022 are scheduled to mature in May 2022 for $69.7 million in aggregate principal amount, and one vessel under our 2021 $21.0 Million Credit Facility for $17.5 million is scheduled to mature in December 2022. While we believe our current financial position, after taking into consideration the pending vessel sales, is adequate to address these cash outflows, a deterioration in economic conditions could cause us to breach the covenants under our financing arrangements and could have a material adverse effect on our business, results of operations, cash flows and financial condition. These circumstances could cause us to seek covenant waivers from our lenders and to pursue other means to raise liquidity, such as through the sale of vessels or in the capital markets, to meet our obligations. Economic conditions and COVID-19 risks Initially, the onset of the COVID-19 pandemic in March 2020 resulted in a sharp reduction in economic activity and a corresponding reduction in the global demand for oil and refined petroleum products. This period of time was marked by extreme volatility in the oil markets and the development of a steep contango in the prices of oil and refined petroleum products. Consequently, an abundance of arbitrage and floating storage opportunities opened up, which resulted in record increases in spot TCE rates late in the first quarter of 2020 and throughout the second quarter of 2020. These market dynamics, which were driven by arbitrage trading rather than underlying consumption, led to a build-up of global oil and refined petroleum product inventories. In June 2020, as underlying oil markets stabilized and global economies began to recover, the excess inventories that built up during this period began to slowly unwind thus causing demand for the seaborne transportation of refined petroleum products to decline. These market conditions, coupled with underlying oil consumption that has yet to reach pre-pandemic levels, had an adverse impact on spot TCE rates throughout 2021. These conditions were exacerbated by the emergence of more contagious, vaccine resistant variants of the virus. Nevertheless, the easing of restrictive measures and successful roll-out of vaccines in most countries throughout the world during 2021 has served as a catalyst for a global economic recovery. Consequently, oil prices continue to push upward on the back of steadily increasing consumption, recently reaching highs not seen since 2014, and existing inventories of refined petroleum products have fallen below multi-year averages. Though these dynamics have set the stage for a long-term recovery, spot TCE rates remained subdued during 2021 as demand failed to exceed pre-pandemic levels. We expect that the COVID-19 pandemic will continue to cause volatility in the commodities markets. The scale and duration of these circumstances is unknowable but could continue to have a material adverse impact on our earnings, cash flow and financial condition. As described in Note 23, in January and March 2022, we entered into agreements to sell 15 vessels in aggregate, which we expect will raise additional liquidity of approximately $196.6 million after the repayment of debt and payment of estimated selling costs as a result of these transactions. We currently project that we will have adequate financial resources to continue in operation and meet our financial commitments (including but not limited to debt service obligations, obligations under sale and leaseback arrangements, commitments under other leasing arrangements, and commitments under our scrubber and BWTS contracts) for a period of at least 12 months from the date of approval of these consolidated financial statements. Accordingly, we continue to adopt the going concern basis in preparing our financial statements. A protracted extension of the adverse market conditions brought on by the COVID-19 pandemic could cause us to breach the covenants under our financing arrangements and could have a material adverse effect on our business, results of operations, cash flows and financial condition. These circumstances could cause us to seek covenant waivers from our lenders and to pursue other means to raise liquidity, such as through the sale of vessels or in the capital markets, to meet our obligations. Remaining contractual maturity on secured and unsecured credit facilities, finance lease liabilities and IFRS-16 lease liabilities The following table details our remaining contractual maturity for our secured and unsecured credit facilities, lease financing and IFRS-16 lease liabilities. The amounts represent the future undiscounted cash flows of the financial liability based on the earliest date on which we can be required to pay. The table includes both interest and principal cash flows. As the interest cash flows are not fixed, the interest amount included has been determined by reference to the projected interest rates as illustrated by the yield curves existing at the reporting date. As of December 31, In thousands of U.S. dollars 2021 2020 Less than 1 month $ 20,172 $ 34,615 1-3 months 98,407 109,849 3 months to 1 year 477,055 328,880 1-3 years 914,599 1,158,802 3-5 years 1,359,473 969,016 5+ years 880,531 942,670 Total $ 3,750,237 $ 3,543,832 All other current liabilities fall due within less than one month. Foreign Exchange Rate Risk Our primary economic environment is the international shipping market. This market utilizes the U.S. Dollar as its functional currency. Consequently, virtually all of our revenues and the majority of our operating expenses are in U.S. Dollars. However, we incur some of our combined expenses in other currencies, particularly the Euro. The amount and frequency of some of these expenses (such as vessel repairs, supplies and stores) may fluctuate from period to period. Depreciation in the value of the U.S. dollar relative to other currencies will increase the U.S. dollar cost of us paying such expenses. The portion of our business conducted in other currencies could increase in the future, which could expand our exposure to losses arising from currency fluctuations. There is a risk that currency fluctuations will have a negative effect on our cash flows. We have not entered into any hedging contracts to protect against currency fluctuations. However, we have some ability to shift the purchase of goods and services from one country to another and, thus, from one currency to another, on relatively short notice. We may seek to hedge this currency fluctuation risk in the future.

Subsequent events

Events After Reporting Period [Abstract]
Subsequent events	Subsequent events Vessels Sales In January 2022, we entered into agreements to sell two MRs (2013 built STI Fontvieille and 2019 built STI Majestic ) and 12 LR1s. The sales prices of STI Fontvieille, STI Majestic, and the 12 LR1s are $23.5 million, $34.9 million, and $413.8 million, respectively. We expect to record an aggregate loss of approximately $48.0 million during the first quarter of 2022 relating to these sales. In February 2022, we exercised the option to repurchase STI Fontvieille and repaid $17.2 million on our AVIC Lease Financing in advance of the sale of the vessel, which closed shortly thereafter. In March 2022, we closed on the sales of the six LR1 vessels, STI Excelsior, STI Executive, STI Excellence, STI Pride, STI Providence and STI Prestige, and we repaid $18.4 million on our Credit Agricole Credit Facility, $39.5 million on our Citibank / K-Sure Credit Facility, $38.7 million on our 2020 $225.0 Million Credit Facility and $21.2 million on our 2021 $43.6 Million Credit Facility as a result of these transactions. In March 2022 we entered into an agreement to sell an MR product tanker ( STI Benicia ) for $26.5 million. This sale is expected to close in the second quarter of 2022. Scorpio Services Holding Limited ("SSH"), a related party, owns a non-controlling 7.5% interest in the buyer of STI Benicia . We expect to record a loss of approximately $5.3 million during the first quarter of 2022 as a result of this agreement. Debt In March 2022, we drew down $3.4 million from our BNPP Sinosure Credit Facility to partially finance the scrubber installations on two LR1 product tankers. Declaration of Dividend On February 11, 2022, our Board of Directors declared a quarterly cash dividend of $0.10 per common share, which was paid on March 15, 2022 to all shareholders of record as of March 2, 2022. Convertible Notes due 2022 and 2025 On March 2, 2022, the conversion rates of the Convertible Notes Due 2022 and Convertible Notes Due 2025, were adjusted to reflect the payment of a cash dividend on March 15, 2022 to all shareholders of record as of March 2, 2022. The new conversion rates for the Convertible Notes due 2022 and 2025 will be 27.3142 of the Company's common shares representing an increase of the prior conversion rates of 0.1571 for each $1,000 principal amount of the Convertible Notes due 2022 and 2025. At the Market Offering Program In January 2021, we entered into a note distribution agreement, or the Distribution Agreement, with B. Riley Securities, Inc., as sales agent, or the Agent, under which we may offer and sell, from time to time, up to an additional $75.0 million aggregate principal amount of our 7.00% Senior Notes due 2025, or the Additional Notes. Since January 1, 2022 and through the date of this report, we issued $0.4 million ) aggregate principal amount of additional Senior Notes Due 2025 for aggregate net proceeds (net of sales agent commissions and offering expenses) of $0.4 million. There is $32.5 million of remaining availability under this program as of date of this report. Conflict in Ukraine The recent military conflict in Ukraine has had a significant direct and indirect impact on the trade of refined petroleum products. This conflict has resulted in the United States, United Kingdom, and the European Union, among other countries, implementing sanctions and executive orders against citizens, entities, and activities connected to Russia. Some of these sanctions and executive orders target the Russian oil sector, including a prohibition on the import of oil from Russia to the United States or the United Kingdom. We cannot foresee what other sanctions or executive orders may arise that affect the trade of petroleum products. Furthermore, the conflict and ensuing international response has disrupted the supply of Russian oil to the global market, and as a result, the price of oil and petroleum products has risen significantly. We cannot predict what effect the higher price of oil and petroleum products will have on demand, and it is possible that the current conflict in Ukraine could adversely affect our financial condition, results of operations, cash flows, financial position and future performance.

Corporate Information And Statement Of IFRS Compliance [Abstract]
Basis of accounting	Basis of accounting The consolidated financial statements incorporate the financial statements of Scorpio Tankers Inc. and its subsidiaries. The consolidated financial statements have been presented in United States dollars, or USD or $, which is the functional currency of Scorpio Tankers Inc. and all its subsidiaries, and have been authorized for issue by the Board of Directors on March 22, 2022. The consolidated financial statements have been prepared in accordance with International Financial Reporting Standards, or IFRS, as issued by the International Accounting Standards Board. All inter-company transactions, balances, income and expenses were eliminated on consolidation.
Going concern	Going concern The financial statements have been prepared in accordance with the going concern basis of accounting as described further in the “Liquidity risk” section of Note 22. Liquidity risk is the risk that an entity will encounter difficulty in raising funds to meet commitments associated with financial instruments. We manage liquidity risk by maintaining adequate reserves and borrowing facilities and by continuously monitoring forecast and actual cash flows. Liquidity risks can manifest themselves when economic conditions deteriorate or when we have significant maturities of our financial instruments. As of December 31, 2021, the financings for four vessels under our Citibank / K-Sure Credit Facility for $76.8 million in aggregate and the financing for one vessel under our Credit Agricole Credit Facility for $16.5 million are scheduled to mature within 2022. Additionally, the financings for three vessels under our Credit Agricole Credit Facility for $49.1 million in aggregate are scheduled to mature during the first quarter of 2023. As described in Note 23, in January and March 2022, we entered into agreements to sell 15 vessels, including all of the vessels that are collateralized under the aforementioned credit facilities, within 12 months from the date of these financial statements. Furthermore, our Convertible Notes due 2022 are scheduled to mature in May 2022 for $69.7 million in aggregate principal amount, and one vessel under our 2021 $21.0 Million Credit Facility for $17.5 million is scheduled to mature in December 2022. While we believe our current financial position, after taking into consideration the pending vessel sales, is adequate to address these cash outflows, a deterioration in economic conditions could cause us to breach the covenants under our financing arrangements and could have a material adverse effect on our business, results of operations, cash flows and financial condition. These circumstances could cause us to seek covenant waivers from our lenders and to pursue other means to raise liquidity, such as through the sale of vessels or in the capital markets, to meet our obligations.
Revenue recognition	Revenue recognition Revenue earned by our vessels is comprised of pool revenue, time charter revenue and voyage revenue. (1) Pool revenue for each vessel is determined in accordance with the profit sharing terms specified within each pool agreement. In particular, the pool manager aggregates the revenues and expenses of all of the pool participants and distributes the net earnings to participants based on: • the pool points attributed to each vessel (which are determined by vessel attributes such as cargo carrying capacity, fuel consumption, and construction characteristics); and • the number of days the vessel participated in the pool in the period . (2) Time charter agreements are when our vessels are chartered to customers for a fixed period of time at rates that are generally fixed, but may contain a variable component based on inflation, interest rates, or current market rates. (3) Voyage charter agreements are charter hires, where a contract is made in the spot market for the use of a vessel for a specific voyage for a specified charter rate. Of these revenue streams, revenue generated in the spot market from voyage charter agreements is within the scope of IFRS 15 - Revenue from Contracts with Customers, which was issued by the International Accounting Standards Board on May 28, 2014 and applied to an entity's first annual IFRS financial statements for a period beginning on or after January 1, 2018. IFRS 15 amended the existing accounting standards for revenue recognition and is based on principles that govern the recognition of revenue at an amount an entity expects to be entitled when products or services are transferred to customers. Revenue generated from pools and time charters is accounted for as revenue earned under operating leases and is therefore within the scope of IFRS 16 - Leases . IFRS 16, Leases , was issued by the International Accounting Standards Board on January 13, 2016 and applied to an entity's first annual IFRS financial statements for a period beginning on or after January 1, 2019. IFRS 16 amended the definition of what constitutes a lease to be a contract that conveys the right to control the use of an identified asset if the lessee has both (i) the right to obtain substantially all of the economic benefits from the use of the identified asset, and (ii) the right to direct the use of the identified asset throughout the period of use. We have determined that our existing pool and time charter-out arrangements meet the definition of leases under IFRS 16, with the Company as lessor, on the basis that the pool or charterer manages the vessels in order to enter into transportation contracts with their customers, and thereby enjoys the economic benefits derived from such arrangements. Furthermore, the pool or charterer can direct the use of a vessel (subject to certain limitations in the pool or charter agreement) throughout the period of use. Moreover, under IFRS 16, we are also required to identify the lease and non-lease components of revenue and account for each component in accordance with the applicable accounting standard. In time charter-out or pool arrangements, we have determined that the lease component is the vessel and the non-lease component is the technical management services provided to operate the vessel. These components are accounted for as follows: • All fixed lease revenue earned under these time charter-out arrangements is recognized on a straight-line basis over the term of the lease. • Lease revenue earned under our pool arrangements is recognized as it is earned, since it is 100% variable. • The non-lease component is accounted for as services revenue under IFRS 15 - Revenue from Contracts with Customers. This revenue is recognized “over time” as the customer (i.e. the pool or the charterer) is simultaneously receiving and consuming the benefits of the service. The accounting for our different revenue streams pursuant to the above accounting standards is therefore summarized as follows: Pool revenue We recognize pool revenue based on quarterly reports from the pools which identifies the number of days the vessel participated in the pool, the total pool points for the period, the total pool revenue for the period, and the calculated share of pool revenue for the vessel. Spot market revenue For vessels operating in the spot market, we recognize revenue ‘over time’ as the customer (i.e. the charterer) is simultaneously receiving and consuming the benefits of the vessel. Under IFRS 15, the performance obligation has been identified as the transportation of cargo from one point to another. Therefore, in a spot market voyage under IFRS 15, revenue is recognized on a pro-rata basis commencing on the date that the cargo is loaded and concluding on the date of discharge. Time charter revenue Time charter revenue is recognized as services are performed based on the daily rates specified in the time charter contract.
Voyage expenses and vessel operating costs	Voyage expenses Voyage expenses primarily include bunkers, port charges, canal tolls, cargo handling operations and brokerage commissions paid by us under voyage charters for vessels trading in the spot market. Under IFRS 15, voyage costs incurred in the fulfillment of a voyage charter are deferred and amortized over the course of the charter commencing on the date that the cargo is loaded and concluding on the date of discharge. Voyage costs are only deferred if they (i) relate directly to such charter, (ii) generate or enhance resources to be used in meeting obligations under the charter, and (iii) are expected to be recovered. Vessel operating costs
Earnings / (Loss) per share	Earnings / (Loss) per share Basic earnings / (loss) per share is calculated by dividing net income / (loss) attributable to equity holders of the parent by the weighted average number of common shares outstanding. Diluted earnings / (loss) per share is calculated by adjusting the net income / (loss) attributable to equity holders of the parent and the weighted average number of common shares used for calculating basic income / (loss) per share for the effects of all potentially dilutive shares. Such dilutive common shares are excluded when the effect would be to increase earnings per share or reduce a loss per share. In the years ended December 31, 2021, 2020 and 2019, there were potentially dilutive items as a result of our (i) 2013 Equity Incentive Plan (as defined in Note 14), (ii) our Convertible Notes due 2019, (iii) our Convertible Notes due 2022, and (iv) our Convertible Notes due 2025 (all of which are described in Note 12). We apply the if-converted method when determining diluted earnings / (loss) per share. This requires the assumption that all potential ordinary shares with respect to our Convertible Notes due 2019, Convertible Notes due 2022, and Convertible Notes due 2025 have been converted into ordinary shares at the beginning of the period or, if not in existence at the beginning of the period, the date of the issue of the financial instrument or the granting of the rights by which they are granted. Under this method, once potential ordinary shares are converted into ordinary shares during the period, the dividends, interest and other expense associated with those potential ordinary shares will no longer be incurred. The effect of conversion, therefore, is to increase income (or reduce losses) attributable to ordinary equity holders as well as the number of shares in issue. Conversion will not be assumed for purposes of computing diluted earnings per share if the effect would be anti-dilutive.
Leases	Leases In a time or bareboat charter-in arrangement, we pay to lease a vessel for a fixed period of time at rates that are generally fixed, but may contain a variable component based on inflation, interest rates, profit sharing or current market rates. In a time charter-in arrangement, the vessel’s owner is responsible for crewing and other vessel operating costs, whereas these costs are the responsibility of the charterer in a bareboat charter-in arrangement. Prior to the adoption of IFRS 16 - Leases in January 2019, the costs associated with these arrangements were recorded as charterhire expense. IFRS 16 - Leases amended the existing accounting standards to require lessees to recognize, on a discounted basis, the rights and obligations created by the commitment to lease assets on the balance sheet as right-of-use assets and corresponding lease liabilities, unless the term of the lease is 12 months or less. As of December 31, 2021, we had 22 bareboat chartered-in vessels which are being accounted for under IFRS 16, Leases as right of use assets and related lease liabilities. Under IFRS 16, there is no charterhire expense for these vessels as the right of use assets are depreciated on a straight-line basis (through depreciation expense) over the lease term, and the lease liability is amortized over that same period (with a portion of each payment allocated to principal and a portion allocated to interest expense). We recorded charterhire expense during the year ended December 31, 2019 for certain vessels that were bareboat chartered-in for terms that were less than 12 months upon the date of transition to IFRS 16.
Foreign currencies	Foreign currencies The individual financial statements of Scorpio Tankers Inc. and each of its subsidiaries are presented in the currency of the primary economic environment in which we operate (its functional currency), which in all cases is U.S. dollars. For the purpose of the consolidated financial statements, our results and financial position are also expressed in U.S. dollars. In preparing the financial statements of Scorpio Tankers Inc. and each of its subsidiaries, transactions in currencies other than the U.S. dollar are recorded at the rate of exchange prevailing on the dates of the transactions. At the end of each reporting period, monetary assets and liabilities denominated in other currencies are translated into the functional currency at rates ruling at that date. All resultant exchange differences have been recognized in the consolidated statements of income or loss. The amounts charged to the consolidated statements of income or loss during the years ended December 31, 2021, 2020 and 2019 were not significant.
Segment reporting	Segment reporting During the years ended December 31, 2021, 2020 and 2019, we owned, lease financed, or chartered-in vessels spanning four different vessel classes, Handymax, MR, LR1 and LR2, all of which earn revenues in the seaborne transportation of refined petroleum products in the international shipping markets. Each vessel within these segments also exhibits similar long-term financial performance and similar economic characteristics to the other vessels within the respective vessel class, thereby meeting the aggregation criteria pursuant to IFRS 8 - Operating Segments . We have therefore chosen to present our segment information by vessel class using the aggregated information from the individual vessels. Segment results are evaluated based on reported net income or loss from each segment. The accounting policies applied to the reportable segments are the same as those used in the preparation of our consolidated financial statements.
Vessels and drydock	Vessels and drydock Our fleet is measured at cost, which includes the cost of work undertaken to enhance the capabilities of the vessels, less accumulated depreciation and impairment losses. Depreciation is calculated on a straight-line basis to the estimated residual value over the anticipated useful life of the vessel from the date of delivery. We estimate the useful lives of our vessels to be 25 years. Vessels under construction are not depreciated until such time as they are ready for use. The residual value is estimated as the lightweight tonnage of each vessel multiplied by scrap value per ton. The scrap value per ton is estimated taking into consideration the historical four-year average scrap market rates available at the balance sheet date with changes accounted for in the period of change and in future periods. The vessels are required to undergo planned drydocks for replacement of certain components, major repairs and maintenance of other components, which cannot be carried out while the vessels are operating, approximately every 30 months or 60 months depending on the nature of work and external requirements. These drydock costs are capitalized and depreciated on a straight-line basis over the estimated period until the next drydock. In deferred drydocking, we only include direct costs that are incurred as part of the drydocking to meet regulatory requirements, or are expenditures that add economic life to the vessel, increase the vessel’s earnings capacity or improve the vessel’s efficiency. Direct costs include shipyard costs as well as the costs of placing the vessel in the shipyard. Expenditures for normal maintenance and repairs, whether incurred as part of the drydocking or not, are expensed as incurred. For an acquired or newly built vessel, a notional drydock component is allocated from the vessel’s cost. The notional drydock cost is estimated by us, based on the expected costs related to the next drydock, which is based on experience and past history of similar vessels, and carried separately from the cost of the vessel. Subsequent drydocks are recorded at actual cost incurred. The drydock component is depreciated on a straight-line basis to the next estimated drydock. The estimated amortization period for a drydock is based on the estimated period between drydocks. When the drydock expenditure is incurred prior to the expiry of the period, the remaining balance is expensed.
Asset acquisitions and Impairment of goodwill	Asset acquisitions In October 2018, the International Accounting Standards Board ("IASB") issued amendments to the definition of a business in IFRS 3 - Business Combinations. 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 to IFRS 3 are effective for annual reporting periods beginning on or after January 1, 2020 and apply prospectively, however earlier application was permitted. As part of these amendments, the IASB introduced an optional fair value concentration test. The purpose of this test is to permit a simplified assessment of whether an acquired set of activities and assets is a business or an asset. Entities may elect whether or not to apply the concentration test on a transaction-by-transaction basis. The concentration test is met if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets. The test is based on gross assets, not net assets, as the IASB concluded that whether a set of activities and assets includes a substantive process does not depend on how the set is financed. In addition, certain assets are excluded from the gross assets considered in the test. If the test is met, the set of activities and assets is determined not to be a business and no further assessment is needed. If the test is not met, or if an entity elects not to apply the test, a detailed assessment must be performed applying the original requirements in IFRS 3. We early adopted these amendments to IFRS 3 in 2019 and applied them to our September 2019 transaction to acquire the leasehold interests in 19 product tankers from Trafigura Maritime Logistics Pte. Ltd. ("Trafigura"). We refer to this transaction as the "Trafigura Transaction". We have accounted for the Trafigura Transaction as an asset acquisition under the amended guidance set forth under IFRS 3, Business Combinations as substantially all of the fair value of the gross assets acquired was concentrated in a group of similar identifiable assets. Moreover, the leasehold interests acquired as part of the Trafigura Transaction qualified as leases under IFRS 16 . Impairment of goodwill Goodwill arising from our 2017 acquisition of Navig8 Product Tankers Inc. was allocated to the cash generating units within each of the respective reportable segments that are expected to benefit from the synergies of the Merger (LR2s and LR1s). Goodwill is not amortized and is tested annually (or more frequently, if impairment indicators arise) by comparing the aggregate carrying amount of the cash generating units within the reportable segment, plus the allocated goodwill, to their recoverable amounts. The recoverable amount of goodwill is measured by the value in use of the cash generating units within the reportable segment. In assessing value in use, the estimated future cash flows of the reportable segment are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the reportable segment for which the estimates of future cash flows have not been adjusted.
Impairment of vessels and drydock, vessels under construction and right of use assets for vessels	Impairment of vessels and drydock, vessels under construction and right of use assets for vessels At each balance sheet date, we review the carrying amount of our vessels and drydock, vessels under construction (if applicable), and right of use assets for vessels to determine whether there is any indication that those assets have suffered an impairment loss. If any such indication exists, the recoverable amount of the vessels and drydock, vessels under construction and right of use assets for vessels is estimated in order to determine the extent of the impairment loss (if any). We treat each vessel and the related drydock as a cash generating unit. Recoverable amount is the higher of the fair value less cost to sell (determined by taking into consideration two valuations from independent ship brokers) and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax 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. Where appropriate, our value in use calculations also incorporate probability weighted assessments of different scenarios (such as potential vessel sales). If the recoverable amount of the cash generating unit is estimated to be less than its carrying amount, the carrying amount of the cash-generating unit is reduced to its recoverable amount. An impairment loss is recognized as an expense immediately. As described in Note 7, our impairment testing at December 31, 2020 resulted in an aggregate impairment charge of $14.2 million as the recoverable amounts of 13 of the MRs in our fleet were less than their carrying amounts. Where an impairment loss subsequently reverses, the carrying amount of the cash generating unit is increased to the revised estimate of its recoverable amount, but so that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognized for the cash generating unit in the prior years. A reversal of impairment is recognized as income immediately.
Inventories	InventoriesInventories consist of lubricating oils and other items including stock provisions, and are stated at the lower of cost and net realizable value. Cost is determined using the first in first out method. Stores and spares are charged to vessel operating costs when purchased. Lubricating oil consumption was $10.0 million, $9.8 million, and $10.3 million for the years ended December 31, 2021, 2020, and 2019, respectively. Lubricating oil consumption is recorded to vessel operating costs.
Interests in joint ventures	Interests in joint ventures In August 2021, we acquired a minority interest in a portfolio of nine product tankers, consisting of five dual-fuel MR methanol tankers (built between 2016 and 2021) which, in addition to traditional petroleum products, are designed to both carry methanol as a cargo and to consume it as a fuel, along with four ice class 1A LR1 product tankers. As part of this agreement, we acquired a 50% interest in a joint venture that ultimately has a minority interest in the entities that own the vessels for final consideration of $6.7 million. A joint venture is an arrangement where we have joint control and have rights to the net assets of the arrangement, rather than rights to the joint venture's assets and obligations for its liabilities. We account for our interest in this joint venture using the equity method pursuant to IFRS 11 - Joint arrangements . Under this guidance, the investment is initially measured at cost, and the carrying amount of the investment is adjusted in subsequent periods based on our share of profits or losses from the joint venture (adjusted for any fair value adjustments made upon initial recognition). Any distributions received from the joint venture reduce the carrying amount. This investment is described in Note 8.
Borrowing costs	Borrowing costs Borrowing costs directly attributable to the acquisition, construction or production of qualifying assets, which are assets that necessarily take a substantial period of time (for example, the time period necessary to construct a vessel) to get ready for their intended use or sale, are added to the cost of those assets, until such time as the assets are substantially ready for their intended use or sale. Investment income earned on the temporary investment of specific borrowings pending their expenditure on qualifying assets is deducted from the borrowing costs eligible for capitalization. All other borrowing costs are recognized in the consolidated statement of income or loss in the period in which they are incurred.
Financial instruments	Financial instruments IFRS 9, Financial instruments , sets out requirements for recognizing and measuring financial assets, financial liabilities and some contracts to buy or sell non-financial items. Financial assets and financial liabilities are recognized in our balance sheet when we become a party to the contractual provisions of the instrument.
Financial assets	Financial assets All financial assets are recognized and derecognized on a trade date where the purchase or sale of a financial asset is under a contract whose terms require delivery within the timeframe established by the market concerned, and are initially measured at fair value, plus transaction costs, except for those financial assets classified as at fair value through profit or loss, which are initially measured at fair value. Financial assets are classified into the following specified categories: financial assets "at fair value through profit or loss", or FVTPL, "at fair value through other comprehensive income" or at amortized cost on the basis of the Company’s business model for managing financial assets and the contractual cash flow characteristics of the financial asset. Income is recognized on an effective interest basis for debt instruments other than those financial assets classified as at FVTPL. Financial assets at amortized cost Financial assets are measured at amortized cost if both of the following conditions are met: • the financial asset is held within a business model whose objective is to hold financial assets in order to collect contractual cash flows; and • the contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. Financial assets at fair value through other comprehensive income Financial assets are measured at fair value through other comprehensive income if both of the following conditions are met: • the financial asset is held within a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets; and • the contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. Financial assets at FVTPL Financial assets are classified as at FVTPL where the financial asset is held for trading. A financial asset is classified as held for trading if: • it has been acquired principally for the purpose of selling in the near future; or • it is a part of an identified portfolio of financial instruments that we manage together and has a recent actual pattern of short-term profit-taking; or • it is a derivative that is not designated and effective as a hedging instrument. Financial assets at FVTPL are stated at fair value, with any resultant gain or loss recognized in the statement of income or loss. The net gain or loss recognized in income or loss incorporates any dividend or interest earned on the financial asset. Fair value is determined in the manner described in Note 22.
Accounts receivable	Accounts receivable Amounts due from the Scorpio Pools and other receivables that have fixed or determinable payments and are not quoted in an active market are classified as accounts receivable. Accounts receivable without a significant financing component are initially measured at their transaction price and subsequently measured at amortized cost, less any impairment (as discussed below). Interest income is recognized by applying the effective interest rate, except for short-term receivables when the recognition of interest would be immaterial.
Impairment of financial assets	Impairment of financial assets IFRS 9 introduced the 'expected credit loss' (ECL) model to determine and recognize impairments. ECLs are a probability-weighted estimate of credit losses and are measured as the present value of all cash shortfalls (i.e. the difference between cash flows due to the entity in accordance with the contract and cash flows that we expect to receive). ECLs are discounted at the effective interest rate of the financial asset. Under IFRS 9, credit losses are recognized earlier than under IAS 39. Under the general model to ECLs under IFRS 9, loss allowances are measured in two different ways: • 12-month ECLs : 12-month ECLs are the expected credit losses that may result from default events on a financial instrument that are possible within the 12 months after the reporting date. 12-month ECLs are utilized when a financial asset has a low credit risk at the reporting date or has not had a significant increase in credit risk since initial recognition. • Lifetime ECLs : these are ECLs that result from all possible default events over the expected life of a financial instrument. Lifetime ECLs are determined when an impaired financial asset has been purchased or originated or when there has been a significant increase in credit risk since initial recognition IFRS 9 also permits operational simplifications for trade receivables, contract assets and lease receivables because they are often held by entities that do not have sophisticated credit risk management systems (i.e. the ‘simplified model’). These simplifications eliminate the need to calculate 12-month ECLs and to assess when a significant increase in credit risk has occurred. Under the simplified approach: • For trade receivables or contract assets that do not contain a significant financing component, the loss allowance is required to be measured at initial recognition and throughout the life of the receivable at an amount equal to lifetime ECL. • For finance lease receivables, operating lease receivables, or trade receivables or contract assets that do contain a significant financing component, IFRS 9 permits an entity to choose as its accounting policy to measure the loss allowance using the general model or the simplified model (i.e. at an amount equal to lifetime expected credit losses). We measure loss allowances for all trade and lease receivables under the simplified model using the lifetime ECL approach. When estimating ECLs, we consider reasonable and supportable information that is available without undue cost or effort at the reporting date about past events, current conditions and forecasts of future economic conditions.
Cash and cash equivalents	Cash and cash equivalents Cash and cash equivalents comprise cash on hand and demand deposits, and other short-term highly-liquid investments with original maturities of three months or less, that are readily convertible to a known amount of cash and are subject to an insignificant risk of changes in value. The carrying value of cash and cash equivalents approximates fair value due to the short-term nature of these instruments.
Restricted cash	Restricted cash We placed deposits in debt service reserve accounts under the terms and conditions set forth under our Citibank / K-Sure Credit Facility, ABN AMRO / K-Sure Credit Facility, and the lease financing arrangements with Bank of Communications Financial Leasing (LR2s). The funds in these accounts are expected to be applied against the principal balance of these facilities upon maturity. The activity within these accounts (which is adjusted from time to time based on prevailing interest rates) is recorded as financing activities on our consolidated statements of cash flows.
Financial liabilities	Financial liabilities Financial liabilities are classified as either financial liabilities at amortized cost or financial liabilities at FVTPL. There were no financial liabilities recorded at FVTPL during the years ended December 31, 2021 or December 31, 2020. Financial liabilities at amortized cost Financial liabilities, including borrowings, are initially measured at fair value, net of transaction costs. Other financial liabilities are subsequently measured at amortized cost using the effective interest method. Financial liabilities at FVTPL Financial liabilities not classified at amortized cost are classified as FVTPL. Financial liabilities at FVTPL are stated at fair value, with any resultant gain or loss recognized in the Statement of Income or Loss. The net gain or loss recognized in the statement of income or loss incorporates any interest paid on the financial liability. Fair value is determined in the manner described in Note 22.
Effective interest method	Effective interest method The effective interest method is a method of calculating the amortized cost of a financial asset and a financial liability. It allocates interest income and interest expense over the relevant period. The effective interest rate is the rate that discounts estimated future cash flows (including all fees or points paid or received that form an integral part of the effective interest rate, transaction costs and other premiums or discounts) over the expected life of the financial asset and financial liability, or, where appropriate, a shorter period.
Convertible debt instruments	Convertible debt instruments Our convertible debt outstanding (which is described in Note 12) is accounted for pursuant to IAS 32 - Financial liabilities and equity . Under IAS 32, we must separately account for the liability and equity components of convertible debt instruments in a manner that reflects the issuer’s economic interest cost. Under this methodology, the instrument is split between its liability and equity components upon initial recognition. The fair value of the liability is measured first, by estimating the fair value of a similar liability that does not have any associated equity conversion option. This becomes the liability’s carrying amount at initial recognition, which is recorded as part of Debt on the consolidated balance sheet. The equity component (the conversion feature) is assigned the residual amount after deducting the amount separately determined for the liability component from the fair value of the instrument as a whole and is recorded as part of Additional paid-in capital within stockholders’ equity on the consolidated balance sheet. Issuance costs are allocated proportionately between the liability and equity components.
Derivative financial instruments	Derivative financial instruments Derivative financial instruments are initially recognized at fair value at the date a derivative contract is entered into and are subsequently remeasured to their fair value at each balance sheet date. A derivative with a positive fair value is recognized as a financial asset whereas a derivative with a negative fair value is recognized as a financial liability. The resulting gain or loss is recognized in income or loss immediately unless the derivative is designated and effective as a hedging instrument, in which event the timing of the recognition in income or loss depends on the nature of the hedging relationship. A derivative is presented as a non-current asset or a non-current liability if the remaining maturity of the instrument is more than 12 months, and it is not expected to be realized or settled within 12 months.
Equity instruments	Equity instruments An equity instrument is any contract that evidences a residual interest in our assets after deducting all of its liabilities. Equity instruments issued by us are recorded at the proceeds received, net of direct issue costs. We had 58,369,516 and 58,093,147 registered shares authorized, issued and outstanding with a par value of $0.01 per share at December 31, 2021 and December 31, 2020, respectively. These shares provide the holders with the same rights to dividends and voting rights.
Provisions	Provisions Provisions are recognized when we have a present obligation as a result of a past event, and it is probable that we will be required to settle that obligation. Provisions are measured at our best estimate of the expenditure required to settle the obligation at the balance sheet date and are discounted to present value where the effect is material.
Dividends	Dividends A provision for dividends payable is recognized when the dividend has been declared in accordance with the terms of the shareholder agreement.
Share based payments	Share based payments The restricted stock awards granted under our 2013 Equity Incentive Plan as described in Note 14 contain only service conditions and are classified as equity settled. Accordingly, the fair value of our restricted stock awards was calculated by multiplying the average of the high and low share price on the grant date and the number of restricted stock shares granted that are expected to vest. In accordance with IFRS 2 - Share based payment , the share price at the grant date serves as a proxy for the fair value of services to be provided by the individual under the plan. Compensation expense related to the awards is recognized ratably over the vesting period, based on our estimate of the number of awards that will eventually vest. The vesting period is the period during which an individual is required to provide service in exchange for an award and is updated at each balance sheet date to reflect any revisions in estimates of the number of awards expected to vest as a result of the effect of service vesting conditions. The impact of the revision of the original estimate, if any, is recognized in the consolidated statement of income or loss such that the cumulative expense reflects the revised estimate, with a corresponding adjustment to equity reserves.
Critical accounting judgments and key sources of estimation uncertainty	Critical accounting judgments and key sources of estimation uncertainty In the application of the accounting policies, we are required to make judgments, estimates and assumptions about the carrying amounts of assets and liabilities that are not readily apparent from other sources. The estimates and associated assumptions are based on historical experience and other factors that are considered to be relevant. Actual results may differ from these estimates. The estimates and underlying assumptions are reviewed on an on-going basis. Revisions to accounting estimates are recognized in the period in which the estimate is revised if the revision affects only that period, or in the period of the revision and future periods if the revision affects both current and future periods. The significant judgments and estimates are as follows: Revenue recognition Our revenue is primarily generated from time charters, spot voyages, or pools (see Note 16 for the components of our revenue generated during the years ended December 31, 2021, 2020 and 2019). Revenue recognition for time charters and pools is generally not as complex or as subjective as voyage charters (spot voyages). Time charters are for a specific period of time at a specific rate per day. For long-term time charters, revenue is recognized on a straight-line basis over the term of the charter. Pool revenues are determined by the pool managers from the total revenues and expenses of the pool and allocated to pool participants using a mechanism set out in the time charter agreement between the vessel owner and the pool. We generated revenue from spot voyages during the years ended December 31, 2021 and December 31, 2020. We recognize spot market revenue ‘over time’ as the customer (i.e. the charterer) is simultaneously receiving and consuming the benefits of the vessel. Under IFRS 15, the performance obligation has been identified as the transportation of cargo from one point to another. Therefore, in a spot market voyage under IFRS 15, revenue is recognized on a pro-rata basis commencing on the date that the cargo is loaded and concluding on the date of discharge. Under IFRS 15, voyage costs incurred in the fulfillment of a voyage charter are deferred and amortized over the course of the charter commencing on the date that the cargo is loaded and concluding on the date of discharge. Voyage costs are only deferred if they (i) relate directly to such charter, (ii) generate or enhance resources to be used in meeting obligations under the charter and (iii) are expected to be recovered. Vessel impairment We evaluate the carrying amounts of our vessels, vessels under construction and right of use assets for vessels to determine whether there is any indication that those vessels have suffered an impairment loss. If any such indication exists, the recoverable amount of vessels is estimated in order to determine the extent of the impairment loss (if any). Recoverable amount is the higher of fair value less costs to sell (determined by taking into consideration vessel valuations from independent ship brokers for each vessel) and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax 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 us to make various estimates including future freight rates, earnings from the vessels and discount rates. All of these items have been historically volatile. As part of our process of assessing fair value less selling costs of the vessel, we obtain vessel valuations for our operating vessels from independent ship brokers on an annual basis or when there is an indication that an asset or assets may be impaired. We generally do not obtain vessel valuations for vessels under construction. If an indication of impairment is identified, the need for recognizing an impairment loss is assessed by comparing the carrying amount of the vessels to the higher of the fair value less selling costs and the value in use. Likewise, if there is an indication that an impairment loss recognized in prior periods no longer exists or may have decreased, the need for recognizing an impairment reversal is assessed by comparing the carrying amount of the vessels to the latest estimate of recoverable amount. At December 31, 2021, we reviewed the carrying amount of our vessels and right of use assets for vessels to determine whether there was an indication that these assets had suffered an impairment. First, we assessed the fair value less the cost to sell of our vessels taking into consideration vessel valuations from independent ship brokers. We then compared the fair value less selling costs to each vessel’s carrying value and, if the carrying value exceeded the vessel’s fair value less selling costs, an indicator of impairment exists. We also considered sustained weakness in the product tanker market or other macroeconomic indicators (such as the COVID-19 pandemic) to be an impairment indicator. Based upon these factors, we determined that impairment indicators did exist at December 31, 2021. Once this determination was made, we prepared a value in use calculation where we estimated each vessel’s future cash flows. We did not record an impairment charge at December 31, 2021 based on the results of this analysis, the details and key assumptions of which are described in Note 7. Vessel lives and residual value The carrying value of each of our vessels represents its original cost at the time it was delivered or purchased less depreciation and impairment. We depreciate our vessels to their residual value on a straight-line basis over their estimated useful lives of 25 years. The estimated useful life of 25 years is management’s best estimate and is also consistent with industry practice for similar vessels. The residual value is estimated as the lightweight tonnage of each vessel multiplied by a forecast scrap value per ton. The scrap value per ton is estimated by taking into consideration the historical four-year scrap market rate average at the balance sheet date, which we update annually. An increase in the estimated useful life of a vessel or in its scrap value would have the effect of decreasing the annual depreciation charge and extending it into later periods. A decrease in the useful life of a vessel or scrap value would have the effect of increasing the annual depreciation charge. When regulations place significant limitations over the ability of a vessel to trade on a worldwide basis, the vessel’s useful life is adjusted to end at the date such regulations become effective. No such regulations have been identified that would have impacted the estimated useful life of our vessels. The estimated salvage value of the vessels may not represent the fair value at any one time since market prices of scrap values tend to fluctuate. Deferred drydock cost We recognize drydock costs as a separate component of each vessel’s carrying amount and amortize the drydock cost on a straight-line basis over the estimated period until the next drydock. We use judgment when estimating the period between when drydocks are performed, which can result in adjustments to the estimated amortization of the drydock expense. If the vessel is disposed of before the next drydock, the remaining balance of the deferred drydock is written-off and forms part of the gain or loss recognized upon disposal of vessels in the period when contracted. We expect that our vessels will be required to be drydocked approximately every 30 to 60 months for major repairs and maintenance that cannot be performed while the vessels are operating. Costs capitalized as part of the drydock include actual costs incurred at the drydock yard and parts and supplies used in making such repairs.
Adoption of new and amended IFRS and IFRIC interpretations from January 1, 2020	Adoption of new and amended IFRS and IFRIC interpretations from January 1, 2021 No significant standards and interpretations were adopted during the year ended December 31, 2021. Standards and Interpretations issued and adopted in 2020 • Amendments to IAS 1 and IAS 8 - Definition of Material : • Amendments to IFRS 9, IAS 39 and IFRS 7 - Interest Rate Benchmark Reform The adoption of these standards did not have a significant impact on these consolidated financial statements. Standards and Interpretations issued yet not adopted Additionally, at the date of authorization of these consolidated financial statements, the following Standards which have not been applied in these consolidated financial statements were issued but not yet effective. We do not expect that the adoption of these standards in future periods will have a significant impact on our financial statements. • Annual Improvements to IFRS Standards 2018-2020, which are summarized as follows and are effective for annual periods beginning on or after January 1, 2022: IFRS 9 Financial Instruments - The amendment clarifies which fees an entity includes when it applies the '10 per cent' test in paragraph B3.3.6 of IFRS 9 in assessing whether to derecognize a financial liability. An entity includes only fees paid or received between the entity (the borrower) and the lender, including fees paid or received by either the entity or the lender on the other's behalf. IFRS 16 Leases - The amendment to Illustrative Example 13 accompanying IFRS 16 removes from the example of the illustration of the reimbursement of leasehold improvements by the lessor in order to resolve any potential confusion regarding the treatment of lease incentives that might arise because of how lease incentives are illustrated in that example. • Amendments to IFRS 3 - Reference to the Conceptual Framework - To update reference to the Conceptual Framework without significantly changing the requirements in the standard. The effective date is for annual periods beginning on or after January 1, 2022. • Amendments to IAS 16 - Property, Plant and Equipment - Proceeds before Intended Use - To prohibit deducting from the cost of an item of property, plant and equipment any proceeds from selling items produced while bringing that asset to the location and condition necessary for it to be capable of operating in the manner intended by management and instead requires the recognition of the proceeds from selling such items, and the cost of producing those items, in profit or loss. The effective date is for annual periods beginning on or after January 1, 2022. • Amendments to IAS 37 - Onerous Contracts - Cost of Fulfilling a Contract - To specify that the 'cost of fulfilling' a contract comprises the 'costs that relate directly to the contract' and that costs that relate to a contract can either be incremental costs of fulfilling that contract or an allocation of other costs that relate directly to fulfilling contracts. The effective date is for annual periods beginning on or after January 1, 2022. • Amendments to IAS 1 - Classification of Liabilities as Current or Non-Current - To promote consistency in applying the requirements to determine whether debt and other liabilities with an uncertain settlement date should be classified as current or non-current. The effective date is not earlier than January 1, 2024. • Amendments to IAS 1 - Disclosure of Accounting Policies - To require entities to disclose material accounting policies, instead of significant accounting policies. The amendments clarify, among other things, that accounting policy information may be material because of its nature, even if the related amounts are immaterial. The effective date is for annual periods beginning on or after January 1, 2023. • Amendment to IAS 12 - Deferred Tax Related to Assets and Liabilities Arising from a Single Transaction - These amendments require companies to recognize deferred tax on transactions that, on initial recognition give rise to equal amounts of taxable and deductible temporary differences. The effective date is for annual periods beginning on or after January 1, 2023. • Amendment to IAS 8 - Changes in Accounting Estimates - The definition of a change in accounting estimates is replaced with a definition of accounting estimates. Under the new definition, accounting estimates are “monetary amounts in financial statements that are subject to measurement uncertainty”. The Board clarified that a change in accounting estimate that results from new information or new developments is not the correction of an error. In addition, the effects of a change in an input or a measurement technique used to develop an accounting estimate are changes in accounting estimates if they do not result from the correction of prior period errors. A change in an accounting estimate may affect only the current period’s profit or loss, or the profit or loss of both the current period and future periods. The effect of the change relating to the current period is recognized as income or expense in the current period. The effect, if any, on future periods is recognized as income or expense in those future periods. The effective date is for annual periods beginning on or after January 1, 2023. • Amendments to IFRS 9 – Financial Instruments (IBOR reform) : The changes will impact some of our existing variable rate borrowings and leases. The changes are not expected to have a material impact.

On this basis, the drydock costs for these vessels is being depreciated separately. $4.6 million of notional drydock costs were allocated from the right of use assets recorded for the four MR vessels delivered during 2020 as part of the Trafigura Transaction. (2) This amount represents the write-off of fully depreciated right of use assets related to the bareboat charters on three fixed rate Handymax vessels that expired during the year ended December 31, 2020. The following table summarizes the payments made for the years ended December 31, 2021 and 2020 relating to lease liabilities accounted for under IFRS 16 - Leases : For the year ended December 31, In thousands of U.S. dollars 2021 2020 Interest expense recognized in consolidated statements of income or loss $ 23,641 $ 28,458 Principal repayments recognized in consolidated cash flow statements 56,729 77,913 Net decrease in accrued interest expense 39 (206) Net increase in prepaid interest expense (684) (382) Total payments on lease liabilities under IFRS 16 - Leases $ 79,725 $ 105,783

Schedule of other non-current assets	The following is a table summarizing the components of our Other non-current assets as of December 31, 2021 and 2020: At December 31, In thousands of U.S. dollars 2021 2020 Scorpio LR2 Pool Ltd. pool working capital contributions (1) $ 35,700 $ 35,700 Scorpio MR Pool Ltd. pool working capital contributions (1) 25,200 25,200 Scorpio LR1 Pool Ltd. pool working capital contributions (1) 6,600 6,600 Scorpio Handymax Tanker Pool Ltd. pool working capital contributions (1) 5,661 5,661 Working capital contributions to Scorpio Pools 73,161 73,161 Deposits for exhaust gas cleaning system ('scrubbers') (2) 15,840 5,617 Seller's credit on sale leaseback vessels (3) 10,793 10,192 Investment in dual fuel tanker joint venture (4) 5,736 — Investment in BWTS supplier (5) 1,751 1,751 Capitalized loan fees (6) 1,635 1,424 Other (7) 47 — $ 108,963 $ 92,145 (1) Upon entrance into the Scorpio LR2, LR1, MR, and Handymax Pools, all vessels are required to make initial working capital contributions of both cash and bunkers. Initial working capital contributions are repaid, without interest, upon a vessel’s exit from the pool. Bunkers on board a vessel exiting the pool are credited against such repayment at the actual invoice price of the bunkers. For all owned vessels, we assume that these contributions will not be repaid within 12 months and are thus classified as non-current within Other Assets on the consolidated balance sheets. For chartered-in vessels we classify the amounts as current (within accounts receivable) or non-current (within Other Assets) according to the expiration of the contract. (2) From August 2018 through September 2019, we entered into agreements with two separate suppliers to retrofit a total of 98 of our tankers with scrubbers for total consideration of $146.6 million (which excludes installation costs). Deposits paid for these systems are reflected as investing cash flows within the consolidated statement of cash flows. In April 2020, we reached an agreement to postpone the purchase and installation of scrubbers on 19 of our vessels. In February 2021, we signed an agreement to retain the option to purchase these scrubbers through February 2023. In August 2021, we declared options to purchase and install scrubbers on six vessels (five LR1s and an LR2). The scrubbers are expected to be installed within the first half of 2022. (3) The seller's credit on vessels sold and leased back represents the present value of the deposits of $4.35 million per vessel ($13.1 million in aggregate) that was retained by the buyer as part of the 2017 sale and operating leaseback transactions for STI Beryl , STI Le Rocher and STI Larvotto , which is described in Note 6. This deposit will either be applied to the purchase price of the vessel if a purchase option is exercised or refunded to us at the expiration of the agreement. The present value of this deposit has been calculated based on the interest rate that is implied in the lease, and the carrying value will accrete over the life of the lease, through interest income, until expiration. We recorded $0.6 million and $0.5 million as interest income as part of these agreements during each of the years ended December 31, 2021 and 2020, respectively. (4) In August 2021, we acquired a minority interest in a portfolio of nine product tankers, consisting of five dual-fuel MR methanol tankers (built between 2016 and 2021) which, in addition to traditional petroleum products, are designed to both carry methanol as a cargo and to consume it as a fuel, along with four ice class 1A LR1 product tankers. The dual-fuel MR methanol tankers are currently on long-term time charter contracts greater than five years. As part of this agreement, we acquired a 50% interest in a joint venture that ultimately has a minority interest in the entities that own the vessels for final consideration of $6.7 million. We account for our interest in this joint venture using the equity method pursuant to IFRS 11 - Joint arrangements . Under this guidance, the investment is initially measured at cost, and the carrying amount of the investment is adjusted in subsequent periods based on our share of profits or losses from the joint venture (adjusted for any fair value adjustments made upon initial recognition). Any distributions received from the joint venture reduce the carrying amount. We recorded $0.6 million as our share of net income resulting from this joint venture during the year ended December 31, 2021. Additionally, the joint venture issued a cash distribution of $1.5 million in December 2021, which arose primarily as a result of the sale of two of the LR1s during the fourth quarter of 2021. (5) In July 2018, we executed an agreement to purchase 55 BWTS from an unaffiliated third-party supplier for total consideration of $36.2 million. These systems were expected to be installed over the subsequent five years, as each respective vessel under the agreement comes due for its International Oil Pollution Prevention, or IOPP, renewal survey. Upon entry into this agreement, we also obtained a minority equity interest in this supplier for no additional consideration. We have determined that of the total consideration of $36.2 million, $1.8 million is attributable to the minority equity interest. Since July 2018, aggregate deposits of $32.8 million have been made, of which $31.0 million has been reclassified to "Vessels" upon the installation of these systems. The remaining $1.8 million of this amount has been recorded as the aforementioned minority equity interest, which is being accounted for as a financial asset under IFRS 9. Deposits paid for these systems are reflected as investing cash flows within the consolidated statement of cash flows. Under the terms of the agreement, we were granted a put option, exercisable after one year following the date of the agreement, whereby we can put the shares back to the supplier at a predetermined price. The supplier was also granted a call option, exercisable two years following the date of the agreement, whereby it can buy the shares back from us at a predetermined price, which is greater than the strike price of the put option. Given that the value of this investment is contractually limited to the strike prices set forth in these options, we have recorded the value of the investment at the put option strike price, or $1.8 million in aggregate. The difference in the aggregate value of the investment, based on the spread between the exercise prices of the put and call options, is $0.6 million. We consider this value to be a Level 3 fair value measurement, as this supplier is a private company, and the value has been determined based on unobservable market data (i.e. the proceeds that we would receive if we exercised our put option in full). (6) Represents upfront loan fees on credit facilities that are expected to be used to partially finance the purchase and installation of scrubbers or refinance the indebtedness on certain vessels. These fees are reclassified as deferred financing fees (net of Debt) when the tranche of the loan to which the vessel relates is drawn. (7) Represents prepaid equity issuance costs related to keeping the ATM Program active.

(2) Other activity for this arrangement consists of (i) accretion of the discount; and (ii) the write-off of the discount of $0.6 million related to the refinancing of existing indebtedness. (3) Other activity for this arrangement consists of (i) the amortization of the premium up to the date of the modification of the arrangement (described below), (ii) the recognition upon modification of a non-cash gain of $5.4 million (which was offset by $2.6 million in cash prepayment fees that were paid as part of the lease modification in September 2021 as described further below) and (iii) the accretion of the discount after the date of the modification. (4) Other activity for this arrangement represents the non-cash entry to reduce lease liabilities of $0.4 million when these leases were modified in 2021. The table below details the dividends issued during the years ended December 31, 2021 and 2020, and the corresponding effect on the conversion rate of the Convertible Notes Due 2022: Record Date Dividends per share Share Adjusted Conversion Rate (1) March 2, 2020 $ 0.10 25.8763 June 1, 2020 $ 0.10 26.0200 September 9, 2020 $ 0.10 26.2463 November 23, 2020 $ 0.10 26.4810 March 2, 2021 $ 0.10 26.6617 May 21, 2021 $ 0.10 26.7879 September 9, 2021 $ 0.10 26.9419 December 3, 2021 $ 0.10 27.1571 (1) Per $1,000 principal amount of the Convertible Notes. For the year ended December 31, In thousands of U.S. dollars 2021 2020 2019 Interest expense on debt, net of capitalized interest (1) $ 115,983 $ 132,423 $ 162,738 Accretion of convertible notes (as described in Note 12) 13,265 8,413 11,375 Amortization of deferred financing fees 7,570 6,657 7,041 Loss on extinguishment of debt and write-off of deferred financing fees (2) 3,604 4,056 1,466 Accretion of premiums and discounts on debt (3) 3,682 3,422 3,615 Total financial expenses $ 144,104 $ 154,971 $ 186,235 (1) The decrease in interest expense, net of capitalized interest during the year ended December 31, 2021 is primarily attributable to lower average LIBOR rates compared to the year ended December 31, 2020. As a result of the onset of the COVID-19 pandemic in March 2020, LIBOR rates decreased significantly during the year ended December 31, 2020. Given the timing of when interest rates are fixed on our variable rate borrowings, this decrease primarily impacted our interest expense in the second half of that year and throughout 2021. The average carrying value of our debt was relatively unchanged at $3.14 billion as of December 31, 2021 compared to $3.13 billion as of December 31, 2020. The decrease in interest expense during the year ended December 31, 2020 is primarily attributable to lower LIBOR rates. As a result of the COVID-19 pandemic, LIBOR rates decreased significantly during the year ended December 31, 2020. Additionally, we were able to lower the weighted average margin on our variable rate debt through various refinancing initiatives commencing in the fourth quarter of 2019 and throughout 2020. The combination resulted in lower interest expense for the year ended December 31, 2020 compared to December 31, 2019 despite the increase in the average carrying value of our debt to $3.13 billion from $2.91 billion as of December 31, 2020 and 2019, respectively. Interest payable during those periods was offset by interest capitalized of $0.2 million, $1.4 million and $2.8 million, during the years ended December 31, 2021, 2020, and 2019 respectively. (2) The loss on extinguishment of debt and write-off of deferred financing fees during the year ended December 31, 2021 include (i) $3.0 million of write-offs of deferred financing fees related to the refinancing of existing indebtedness on certain vessels and (ii) $0.6 million of write-offs of the discounts related to the refinancing of existing indebtedness on certain vessels. The loss on extinguishment of debt and write-off of deferred financing fees during the year ended December 31, 2020 include (i) $2.7 million of write-offs of deferred financing fees related to the refinancing of existing indebtedness on certain vessels, (ii) $2.0 million of cash prepayment fees, primarily from the CSSC Lease Financing (as described in Note 12), offset by (iii) $0.7 million of write-offs of the premium and discounts related to the refinancing of existing indebtedness on certain vessels. The loss on extinguishment of debt and write-off of deferred financing fees during the year ended December 31, 2019 includes write-offs of deferred financing fees of (i) $1.2 million related to the refinancing of existing indebtedness on certain vessels, and (ii) $0.3 million related to the redemption of the Senior Notes Due 2019.

Related Party [Abstract]
Disclosure of transactions between related parties	Transactions with entities controlled by the Lolli-Ghetti family (herein referred to as related parties) in the consolidated statements of income or loss and balance sheets are as follows: For the year ended December 31, In thousands of U.S. dollars 2021 2020 2019 Pool revenue (1) Scorpio MR Pool Limited $ 256,874 $ 340,937 $ 261,727 Scorpio LR2 Pool Limited 180,912 369,476 260,893 Scorpio Handymax Tanker Pool Limited 50,143 105,355 103,150 Scorpio LR1 Pool Limited 47,053 87,028 66,009 Voyage revenue (2) — 2,334 — Voyage expenses (3) (1,461) (3,507) (2,414) Vessel operating costs (4) (35,427) (33,896) (31,732) Administrative expenses (5) (13,557) (13,876) (12,975) (1) These transactions relate to revenue earned in the Scorpio Pools. The Scorpio Pools are related parties. When our vessels are in the Scorpio Pools, SCM, the pool manager, charges fees of $300 per vessel per day with respect to our LR1/Panamax and Aframax vessels, $250 per vessel per day with respect to our LR2 vessels, and $325 per vessel per day with respect to each of our Handymax and MR vessels, plus a commission of 1.50% on gross revenue per charter fixture. These are the same fees that SCM charges other vessels in these pools, including third party vessels. In September 2018, we entered into an agreement with SCM whereby SCM reimbursed a portion of the commissions that SCM charges the Company’s vessels to effectively reduce such to 0.85% of gross revenue per charter fixture, effective from September 1, 2018 and ending on June 1, 2019. (2) These transactions relate to revenue earned in the spot market on voyages chartered through SSH, a related party. (3) Related party expenditures included within voyage expenses in the consolidated statements of income or loss consist of the following: • Expenses due to SCM, a related party, for commissions related to the commercial management services provided by SCM under the commercial management agreement for vessels that are not in one of the Scorpio Pools. SCM’s services include securing employment, in the spot market and on time charters, for our vessels. When not in one of the Scorpio Pools, each vessel pays (i) flat fees of $250 per day for LR1/Panamax and LR2/Aframax vessels and $300 per day for Handymax and MR vessels and (ii) commissions of 1.25% of their gross revenue per charter fixture. These expenses are included in voyage expenses in the consolidated statements of income or loss. In September 2018, we entered into an agreement with SCM whereby SCM reimbursed a portion of the commissions that SCM charges the Company’s vessels to effectively reduce such to 0.85% of gross revenue per charter fixture, effective from September 1, 2018 and ending on June 1, 2019. • Bunkers of $2.6 million, $3.6 million, and $0.8 million were purchased from a related party bunker provider during the years ended December 31, 2021, 2020, and 2019, respectively. These bunkers were purchased when our vessels were operating in the spot market, outside of the Scorpio Pools. Approximately $1.4 million, $2.9 million, and $0.3 million, respectively, of these purchases were consumed during the spot market voyages, and the remaining unconsumed portion was considered a working capital contribution to the pool (see below for a description on the accounting for working capital contributions to the Scorpio Pools) when the vessels re-joined the pools during the years ended December 31, 2021 and 2020, respectively. • Voyage expenses of $19,175, $4,925 and $4,357 charged by a related party port agent during the years ended December 31, 2021, 2020. and 2019 respectively. SSH has a majority equity interest in a port agent that provides supply and logistical services for vessels operating in its regions. (4) Related party expenditures included within vessel operating costs in the consolidated statements of income or loss consist of the following: • Technical management fees of $32.7 million, $31.9 million, and $30.0 million charged by SSM, a related party, during the years ended December 31, 2021, 2020 and 2019 respectively. SSM’s services include day-to-day vessel operations, performing general maintenance, monitoring regulatory and classification society compliance, customer vetting procedures, supervising the maintenance and general efficiency of vessels, arranging the hiring of qualified officers and crew, arranging and supervising drydocking and repairs, purchasing supplies, spare parts and new equipment for vessels, appointing supervisors and technical consultants, and providing technical support. SSM administers the payment of salaries to our crew on our behalf. The crew wages that were administered by SSM (and disbursed through related party subcontractors of SSM) were $152.0 million, $146.0 million, and $138.9 million during the years ended December 31, 2021, 2020, and 2019 respectively. SSM's annual technical management fee is a fixed fee of $175,000 per vessel plus certain itemized expenses pursuant to the technical management agreement. • Vessel operating expenses of $2.7 million, $2.0 million, and $1.7 million charged by a related party port agent during the years ended December 31, 2021, 2020 and 2019, respectively. SSH has a majority equity interest in a port agent that provides supply and logistical services for vessels operating in its regions. (5) We have an Amended Administrative Services Agreement with SSH for the provision of administrative staff and office space, and administrative services, including accounting, legal compliance, financial and information technology services. SSH also administers the payroll for certain of our employees. SSH is a related party to us. The services provided to us by SSH may be sub-contracted to other entities within Scorpio. The expenses incurred under this agreement were recorded in general and administrative expenses in the consolidated statement of income or loss and were as follows: • The expense for the year ended December 31, 2021 of $13.6 million included (i) administrative fees of $12.2 million charged by SSH, (ii) restricted stock amortization of $1.3 million, which relates to the issuance of an aggregate of 315,950 shares of restricted stock to SSH employees for no cash consideration pursuant to the 2013 Equity Incentive Plan, and (iii) the reimbursement of expenses of $51,962 to SSH and $14,726 to SCM. • The expense for the year ended December 31, 2020 of $13.9 million included (i) administrative fees of $12.6 million charged by SSH, (ii) restricted stock amortization of $1.2 million, which relates to the issuance of an aggregate of 315,950 shares of restricted stock to SSH employees for no cash consideration pursuant to the 2013 Equity Incentive Plan and (iii) the reimbursement of expenses of $19,772 to SSH and $45,539 to SCM. • The expense for the year ended December 31, 2019 of $13.0 million included (i) administrative fees of $11.4 million charged by SSH, (ii) restricted stock amortization of $1.1 million, which relates to the issuance of an aggregate of 221,900 shares of restricted stock to SSH employees for no cash consideration pursuant to the 2013 Equity Incentive Plan and (iii) the reimbursement of expenses of $0.2 million to SSH and $0.2 million to SCM. We had the following balances with related parties, which have been included in the consolidated balance sheets: As of December 31, In thousands of U.S. dollars 2021 2020 Assets: Accounts receivable (due from the Scorpio Pools) (1) $ 36,216 $ 26,413 Accounts receivable and prepaid expenses (SSM) (2) 3,426 4,259 Other assets (pool working capital contributions) (3) 73,161 73,161 Liabilities: Accounts payable and accrued expenses (SSM) 9,844 935 Accounts payable and accrued expenses (owed to the Scorpio Pools) 2,548 945 Accounts payable and accrued expenses (SSH) 1,888 404 Accounts payable and accrued expenses (related party port agent) 674 355 Accounts payable and accrued expenses (SCM) 25 58 (1) Accounts receivable due from the Scorpio Pools relate to hire receivables for revenues earned and receivables from working capital contributions. The amounts as of December 31, 2020 included $1.1 million of working capital contributions made on behalf of our vessels to the Scorpio Pools. Upon entrance into such pools, all vessels are required to make working capital contributions of both cash and bunkers. Additional working capital contributions can be made from time to time based on the operating needs of the pools. These amounts are accounted for and repaid as follows: • For vessels in the Scorpio LR2 Pool, Scorpio LR1 Pool, Scorpio MR Pool and Scorpio Handymax Tanker Pool, the initial contribution amount is repaid, without interest, upon a vessel’s exit from the pool no later than six months after the exit date. Bunkers on board a vessel exiting the pool are credited against such repayment at the actual invoice price of the bunkers. For all owned or lease financed vessels we assume that these contributions will not be repaid within 12 months and are thus classified as non-current within other assets on the consolidated balance sheets. • For time or bareboat chartered-in vessels we classify the initial contributions as current (within accounts receivable) or non-current (within other assets) according to the expiration of the contract. Any additional working capital contributions are repaid when sufficient net revenues become available to cover such amounts. (2) Accounts receivable and prepaid expenses from SSM primarily relate to advances made for vessel operating expenses (such as crew wages) that will either be reimbursed or applied against future costs. The table below shows key management remuneration for the years ended December 31, 2021, 2020 and 2019: For the year ended December 31, In thousands of U.S. dollars 2021 2020 2019 Short-term employee benefits (salaries) $ 5,488 $ 10,989 $ 10,821 Share-based compensation (1) 17,476 22,217 21,712 Total $ 22,964 $ 33,206 $ 32,533 (1) Represents the amortization of restricted stock issued under our 2013 Equity Incentive Plan as described in Note 14.

Lease and non lease components	The following table summarizes the lease and non-lease components of revenue from time charter-out and pool revenue during the years ended December 31, 2021, 2020 and 2019. These figures are not readily quantifiable as the Company's contracts (with the Scorpio pools or under time charter-out arrangements) do not separate these components. The Company does not view its pool and time charter-out revenue as two separate streams of revenue. Nevertheless, we have estimated these amounts by reference to (i) third party, published time charter rates for the lease component, and (ii) an approximation of the fair market value of vessel operating expenses for the non-lease component. For the year ended December 31, In thousands of U.S. dollars 2021 2020 2019 Lease component of revenue from time charter-out and pool revenue $ 280,633 $ 548,988 $ 428,781 Non-lease component of revenue from time charter-out and pool revenue 254,349 353,808 265,656 $ 534,982 $ 902,796 $ 694,437

(2) Other activity for this arrangement consists of (i) accretion of the discount; and (ii) the write-off of the discount of $0.6 million related to the refinancing of existing indebtedness. (3) Other activity for this arrangement consists of (i) the amortization of the premium up to the date of the modification of the arrangement (described below), (ii) the recognition upon modification of a non-cash gain of $5.4 million (which was offset by $2.6 million in cash prepayment fees that were paid as part of the lease modification in September 2021 as described further below) and (iii) the accretion of the discount after the date of the modification. (4) Other activity for this arrangement represents the non-cash entry to reduce lease liabilities of $0.4 million when these leases were modified in 2021. The table below details the dividends issued during the years ended December 31, 2021 and 2020, and the corresponding effect on the conversion rate of the Convertible Notes Due 2022: Record Date Dividends per share Share Adjusted Conversion Rate (1) March 2, 2020 $ 0.10 25.8763 June 1, 2020 $ 0.10 26.0200 September 9, 2020 $ 0.10 26.2463 November 23, 2020 $ 0.10 26.4810 March 2, 2021 $ 0.10 26.6617 May 21, 2021 $ 0.10 26.7879 September 9, 2021 $ 0.10 26.9419 December 3, 2021 $ 0.10 27.1571 (1) Per $1,000 principal amount of the Convertible Notes. For the year ended December 31, In thousands of U.S. dollars 2021 2020 2019 Interest expense on debt, net of capitalized interest (1) $ 115,983 $ 132,423 $ 162,738 Accretion of convertible notes (as described in Note 12) 13,265 8,413 11,375 Amortization of deferred financing fees 7,570 6,657 7,041 Loss on extinguishment of debt and write-off of deferred financing fees (2) 3,604 4,056 1,466 Accretion of premiums and discounts on debt (3) 3,682 3,422 3,615 Total financial expenses $ 144,104 $ 154,971 $ 186,235 (1) The decrease in interest expense, net of capitalized interest during the year ended December 31, 2021 is primarily attributable to lower average LIBOR rates compared to the year ended December 31, 2020. As a result of the onset of the COVID-19 pandemic in March 2020, LIBOR rates decreased significantly during the year ended December 31, 2020. Given the timing of when interest rates are fixed on our variable rate borrowings, this decrease primarily impacted our interest expense in the second half of that year and throughout 2021. The average carrying value of our debt was relatively unchanged at $3.14 billion as of December 31, 2021 compared to $3.13 billion as of December 31, 2020. The decrease in interest expense during the year ended December 31, 2020 is primarily attributable to lower LIBOR rates. As a result of the COVID-19 pandemic, LIBOR rates decreased significantly during the year ended December 31, 2020. Additionally, we were able to lower the weighted average margin on our variable rate debt through various refinancing initiatives commencing in the fourth quarter of 2019 and throughout 2020. The combination resulted in lower interest expense for the year ended December 31, 2020 compared to December 31, 2019 despite the increase in the average carrying value of our debt to $3.13 billion from $2.91 billion as of December 31, 2020 and 2019, respectively. Interest payable during those periods was offset by interest capitalized of $0.2 million, $1.4 million and $2.8 million, during the years ended December 31, 2021, 2020, and 2019 respectively. (2) The loss on extinguishment of debt and write-off of deferred financing fees during the year ended December 31, 2021 include (i) $3.0 million of write-offs of deferred financing fees related to the refinancing of existing indebtedness on certain vessels and (ii) $0.6 million of write-offs of the discounts related to the refinancing of existing indebtedness on certain vessels. The loss on extinguishment of debt and write-off of deferred financing fees during the year ended December 31, 2020 include (i) $2.7 million of write-offs of deferred financing fees related to the refinancing of existing indebtedness on certain vessels, (ii) $2.0 million of cash prepayment fees, primarily from the CSSC Lease Financing (as described in Note 12), offset by (iii) $0.7 million of write-offs of the premium and discounts related to the refinancing of existing indebtedness on certain vessels. The loss on extinguishment of debt and write-off of deferred financing fees during the year ended December 31, 2019 includes write-offs of deferred financing fees of (i) $1.2 million related to the refinancing of existing indebtedness on certain vessels, and (ii) $0.3 million related to the redemption of the Senior Notes Due 2019.

(2) Restricted cash are considered Level 1 items due to the liquid nature of these assets. (3) We consider that the carrying amount of accounts receivable approximate their fair value due to the relative short maturity of these instruments. (4) We consider the fair value of our minority interest in our BWTS supplier (as described in Note 8) to be a Level 3 fair value measurement, as this supplier is a private company and the value has been determined based on unobservable market data (i.e. the proceeds that we would receive if we exercised the put option set forth in the agreement in full). Moreover, we consider that its carrying value approximates fair value given that the value of this investment is contractually limited to the strike prices set forth in the put and call options prescribed in the agreement and the difference between the two prices is not significant. The difference in the aggregate value of the investment, based on the spread between the exercise prices of the put and call options is $0.6 million. (5) Non-current working capital contributions to the Scorpio Pools are repaid, without interest, upon a vessel’s exit from the pool. For all owned vessels, we assume that these contributions will not be repaid within 12 months and are thus classified as non-current within Other Assets on the consolidated balance sheets. We consider that their carrying values approximate fair value given that the amounts due are contractually fixed based on the terms of each pool agreement. (6) The seller's credit on lease financed vessels represents the present value of the deposits of $4.35 million per vessel ($13.1 million in aggregate) that was retained by the buyer as part of the sale and operating leasebacks of STI Beryl , STI Le Rocher and STI Larvotto . This deposit will either be applied to the purchase price of the vessel if a purchase option is exercised or refunded to us at the expiration of the agreement. This deposit has been recorded as a financial asset measured at amortized cost. The present value of this deposit has been calculated based on the interest rate that is implied in the lease, and the carrying value will accrete over the life of the lease using the effective interest method, through interest income, until expiration. We consider that its carrying value approximates fair value given that its value is contractually fixed based on the terms of each lease. (7) We consider that the carrying amounts of accounts payable and accrued expenses approximate the fair value due to the relative short maturity of these instruments. (8) The carrying value of our secured bank loans are measured at amortized cost using the effective interest method. We consider that their carrying value approximates fair value because the interest rates on these instruments change with, or approximate, market interest rates and the credit risk of the Company has remained stable. Accordingly, we consider their fair value to be a Level 2 measurement. These amounts are shown net of $6.4 million and $12.3 million of unamortized deferred financing fees as of December 31, 2021 and 2020, respectively. (9) The carrying value of our obligations due under sale and leaseback arrangements are measured at amortized cost using the effective interest method. With the exception of three fixed rate sale and leaseback arrangements, we consider that their carrying value approximates fair value because the interest rates on these instruments change with, or approximate, market interest rates and the credit risk of the Company has remained stable. The fair value of leases with fixed payments are measured at the net discounted value of the remaining minimum lease payments using our incremental borrowing rate at December 31, 2021. Accordingly, we consider their fair value to be a Level 2 measurement. These amounts are shown net of $13.1 million and $8.7 million of unamortized deferred financing fees as of December 31, 2021 and 2020, respectively. (10) The carrying value of our lease obligations that are being accounted for under IFRS 16 are measured at the present value of the minimum lease payments under each contract. These leases are mainly comprised of the leases acquired as part of the Trafigura Transaction. We consider that their carrying value approximates fair value because the interest rates on these leases change with, or approximate, market interest rates and the credit risk of the Company has remained stable. The fair value of leases with fixed payments are measured at the net discounted value of the remaining minimum lease payments using our incremental borrowing rate at December 31, 2021 and 2020. Accordingly, we consider their fair value to be a Level 2 measurement. (11) The carrying value of our Senior Notes Due 2025 is measured at amortized cost using the effective interest method. The carrying value of our Senior Notes Due 2025 shown in the table above is their face value. The Senior Notes due 2025 are shown net of $2.3 million of deferred financing fees and $0.2 million of unamortized discount on our consolidated balance sheet as of December 31, 2021. The Senior Notes due 2025 are shown net of $1.4 million of unamortized deferred financing fees on our consolidated balance sheet as of December 31, 2020. Our Senior Notes Due 2025 are quoted on the NYSE under the symbol 'SBBA'. We consider their fair value to be a Level 1 measurement due to their quotation on an active exchange.
Fair values and carrying values of financial liabilities	The fair values and carrying values of our financial instruments at December 31, 2021 and 2020, respectively, are shown in the table below.

(2) Restricted cash are considered Level 1 items due to the liquid nature of these assets. (3) We consider that the carrying amount of accounts receivable approximate their fair value due to the relative short maturity of these instruments. (4) We consider the fair value of our minority interest in our BWTS supplier (as described in Note 8) to be a Level 3 fair value measurement, as this supplier is a private company and the value has been determined based on unobservable market data (i.e. the proceeds that we would receive if we exercised the put option set forth in the agreement in full). Moreover, we consider that its carrying value approximates fair value given that the value of this investment is contractually limited to the strike prices set forth in the put and call options prescribed in the agreement and the difference between the two prices is not significant. The difference in the aggregate value of the investment, based on the spread between the exercise prices of the put and call options is $0.6 million. (5) Non-current working capital contributions to the Scorpio Pools are repaid, without interest, upon a vessel’s exit from the pool. For all owned vessels, we assume that these contributions will not be repaid within 12 months and are thus classified as non-current within Other Assets on the consolidated balance sheets. We consider that their carrying values approximate fair value given that the amounts due are contractually fixed based on the terms of each pool agreement. (6) The seller's credit on lease financed vessels represents the present value of the deposits of $4.35 million per vessel ($13.1 million in aggregate) that was retained by the buyer as part of the sale and operating leasebacks of STI Beryl , STI Le Rocher and STI Larvotto . This deposit will either be applied to the purchase price of the vessel if a purchase option is exercised or refunded to us at the expiration of the agreement. This deposit has been recorded as a financial asset measured at amortized cost. The present value of this deposit has been calculated based on the interest rate that is implied in the lease, and the carrying value will accrete over the life of the lease using the effective interest method, through interest income, until expiration. We consider that its carrying value approximates fair value given that its value is contractually fixed based on the terms of each lease. (7) We consider that the carrying amounts of accounts payable and accrued expenses approximate the fair value due to the relative short maturity of these instruments. (8) The carrying value of our secured bank loans are measured at amortized cost using the effective interest method. We consider that their carrying value approximates fair value because the interest rates on these instruments change with, or approximate, market interest rates and the credit risk of the Company has remained stable. Accordingly, we consider their fair value to be a Level 2 measurement. These amounts are shown net of $6.4 million and $12.3 million of unamortized deferred financing fees as of December 31, 2021 and 2020, respectively. (9) The carrying value of our obligations due under sale and leaseback arrangements are measured at amortized cost using the effective interest method. With the exception of three fixed rate sale and leaseback arrangements, we consider that their carrying value approximates fair value because the interest rates on these instruments change with, or approximate, market interest rates and the credit risk of the Company has remained stable. The fair value of leases with fixed payments are measured at the net discounted value of the remaining minimum lease payments using our incremental borrowing rate at December 31, 2021. Accordingly, we consider their fair value to be a Level 2 measurement.

The carrying value of our Senior Notes Due 2025 shown in the table above is their face value. The Senior Notes due 2025 are shown net of $2.3 million of deferred financing fees and $0.2 million of unamortized discount on our consolidated balance sheet as of December 31, 2021.

Contractual maturity of secured and unsecured credit facilities	The following table details our remaining contractual maturity for our secured and unsecured credit facilities, lease financing and IFRS-16 lease liabilities. The amounts represent the future undiscounted cash flows of the financial liability based on the earliest date on which we can be required to pay. The table includes both interest and principal cash flows. As the interest cash flows are not fixed, the interest amount included has been determined by reference to the projected interest rates as illustrated by the yield curves existing at the reporting date.
