Summary of Significant Accounting Policies | 1. Summary of Significant Accounting Policies Basis of presentation These consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (or GAAP ). They include the accounts of Teekay Corporation (or Teekay ), which is incorporated under the laws of the Republic of the Marshall Islands, its wholly-owned or controlled subsidiaries and any variable interest entities of which Teekay is the primary beneficiary (collectively, the Company ). Teekay's controlled subsidiaries include Teekay Tankers Ltd. (NYSE: TNK) (or Teekay Tankers ). Teekay and its subsidiaries, other than Teekay Tankers, are referred to herein as Teekay Parent . The preparation of these consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from those estimates. Significant intercompany balances and transactions have been eliminated upon consolidation. Certain of Teekay’s significant non-wholly-owned subsidiaries are consolidated in these financial statements even though Teekay owns less than a 50% ownership interest in the subsidiaries. These significant subsidiaries include the following publicly traded subsidiaries: Teekay Tankers Ltd. (or Teekay Tankers ) and, until January 13, 2022 (see below), Teekay LNG Partners L.P. (or Teekay LNG Partners ) (now known as Seapeak LLC (or Seapeak )). As of December 31, 2023, Teekay had no ownership interest in Seapeak (2022 – 0.0%) or Seapeak's general partner. As of December 31, 2023, Teekay owned 28.7% of the capital stock of Teekay Tankers (2022 – 28.5%), including Teekay Tankers’ outstanding shares of Class B common stock, which entitle the holders to five votes per share, subject to a 49% aggregate Class B Common Stock voting power maximum. Teekay maintains control of Teekay Tankers through its ownership of a sufficient number of Class A common shares and Class B common shares, which provide increased voting rights, to maintain a majority voting interest in Teekay Tankers and thus consolidates this subsidiary. Prior to January 13, 2022 (see below), Teekay maintained control of Teekay LNG Partners by virtue of its 100% ownership interest in the general partner of Teekay LNG Partners, which was a publicly-traded partnership. Effective on February 25, 2022, Teekay LNG Partners L.P. converted from a limited partnership formed under the laws of the Republic of the Marshall Islands into a limited liability company formed under the laws of the Republic of the Marshall Islands, and changed its name from “Teekay LNG Partners L.P.” to “Seapeak LLC”. On October 4, 2021, Teekay LNG Partners and Stonepeak, together with affiliates, entered into an agreement and plan of merger pursuant to which Stonepeak would acquire Teekay LNG Partners. In connection with the merger, the Company agreed to sell its general partner interest in Teekay LNG Partners, all of its common units in Teekay LNG Partners and certain subsidiaries which collectively contain the shore-based management operations of Teekay LNG Partners and certain of Teekay LNG Partners’ joint ventures (collectively the Teekay Gas Business ). The transactions closed on January 13, 2022, which resulted in Teekay deconsolidating the Teekay Gas Business for accounting purposes on that date. The presentation of certain information in these consolidated financial statements reflects that the Teekay Gas Business is a discontinued operation of the Company. See Note 21 – Discontinued Operations for further information. Non-Controlling Interests Where Teekay’s ownership interest in a consolidated subsidiary is less than 100%, the non-controlling interests’ share of these non-wholly-owned subsidiaries is reported in the Company’s consolidated balance sheets as a separate component of equity. The non-controlling interests’ share of the net income of these non-wholly-owned subsidiaries is reported in the Company’s consolidated statements of income (loss) as a deduction from the Company’s net income (loss) to arrive at net income attributable to the shareholders of Teekay. The basis for attributing net income or loss of each non-wholly-owned subsidiary to the controlling interest and the non-controlling interest is based on the relative ownership interests of the non-controlling interests compared to the controlling interest (Teekay), which is consistent with how dividends and distributions were paid or were payable for these non-wholly-owned subsidiaries. In periods when vessels are sold by Seapeak or Teekay Tankers that were previously purchased from wholly-owned subsidiaries of Teekay, the amount of the gain or loss from sale allocated to the controlling interest and non-controlling interest is adjusted to reflect the non-controlling interest’s share of the deferred gain or loss that was incurred when Teekay previously sold these vessels from its wholly-owned subsidiaries to its non-wholly-owned subsidiaries Seapeak or Teekay Tankers. As reflected in the table below, during 2021, 2022 and 2023, such vessel sales by Teekay Tankers resulted in increases (decreases) in net income (loss) of Teekay Tankers attributable to the non-controlling interest (controlling interest) by ($1.8) million, $10.6 million and $nil, respectively. Upon the sale and deconsolidation of Seapeak on January 13, 2022, $84.8 million, which is the total unrecognized net deferred gains relating to vessels previously sold from Teekay to Seapeak, was recognized as an increase to net income attributable to non-controlling interests for the year ended December 31, 2022. Prior to its conversion to a limited liability company in February 2022, Seapeak had limited partners and a general partner. Seapeak's general partner was wholly-owned by Teekay until January 13, 2022. Seapeak's limited partners held common units and preferred units. For each quarterly period, the method of attributing Seapeak’s net income (loss) of that period to the non-controlling interests of Seapeak begins by attributing net income (loss) of Seapeak to the non-controlling interests which hold 100% of the preferred units of Seapeak based on the amount of preferred unit distributions declared for the quarterly period. The total net income (loss) of Teekay’s consolidated partially-owned entities and the attribution of that net income (loss) to controlling and non-controlling interests is as follows: Net income (loss) attributable to non-controlling interests Controlling Interest Net income (loss) of consolidated partially-owned entities (1) Non-public partially-owned subsidiaries Preferred unit-holders Earnings (Loss) Total Non-Controlling Interest Earnings (Loss) Total Controlling Interest (Teekay) Teekay Tankers — — 366,909 366,909 146,762 146,762 513,671 Other entities and eliminations — — (127) (127) For the Year End December 31, 2023 — — 366,782 366,782 Seapeak (2) 872 928 (63,728) (61,928) 100,364 100,364 38,436 Teekay Tankers — — 172,857 172,857 56,229 56,229 229,086 Other entities and eliminations — — 24 24 For the Year End December 31, 2022 872 928 109,153 110,953 Seapeak (2) 12,900 25,702 125,016 163,618 91,930 91,930 255,548 Teekay Tankers — — (174,787) (174,787) (67,585) (67,585) (242,372) Other entities and eliminations — — (5) (5) For the Year Ended December 31, 2021 12,900 25,702 (49,776) (11,174) (1) Includes earnings attributable to common and preferred shares. (2) Seapeak forms part of discontinued operations during 2022 and 2021. When Teekay’s non-wholly-owned subsidiaries declare dividends or distributions to their owners or require all of their owners to contribute capital to the non-wholly-owned subsidiaries, such amounts are paid to, or received from, each of the owners of the non-wholly-owned subsidiaries based on the relative ownership interests in the non-wholly-owned subsidiary. As such, any dividends or distributions paid to, or capital contributions received from, the non-controlling interests are reflected as a reduction (dividends or distributions) or an increase (capital contributions) in non-controlling interest in the Company’s consolidated balance sheets. When Teekay’s non-wholly-owned subsidiaries issue additional equity interests to non-controlling interests, Teekay is effectively selling a portion of the non-wholly-owned subsidiaries. Consequently, the proceeds received by the subsidiaries from their issuance of additional equity interests are allocated between non-controlling interests and retained earnings in the Company’s consolidated balance sheets. The portion allocated to non-controlling interests on the Company’s consolidated balance sheets consists of the carrying value of the portion of the non-wholly-owned subsidiary that is effectively disposed of, with the remaining amount attributable to the controlling interests, which consists of the Company’s dilution gain or loss that is reflected in retained earnings. Foreign currency The consolidated financial statements are stated in U.S. Dollars and the functional currency of the Company is the U.S. Dollar. Transactions involving other currencies during the year are converted into U.S. Dollars using the exchange rates in effect at the time of the transactions. At the balance sheet date, monetary assets and liabilities that are denominated in currencies other than the U.S. Dollar are translated to reflect the year-end exchange rates. Resulting gains or losses are reflected in other - net in the accompanying consolidated statements of income (loss). Revenues The Company's voyage charters, time charters and floating production storage and offloading (or FPSO ) contracts (the last of which ended in the first half of 2022), include both a lease component, consisting of the lease of the vessel, and a non-lease component, consisting of the operation of the vessel for the customer. The Company has elected not to separate the non-lease component from the lease component for all such charters where the lease component is classified as an operating lease and certain other required criteria are met, and to account for the combined component as an operating lease. Time-charter contracts accounted for as direct financing leases and sales type leases contain both a lease component (lease of the vessel) and a non-lease component (operation of the vessel). The Company has allocated the contract consideration between the lease component and non-lease component on a relative standalone selling price basis. The standalone selling price of the non-lease component has been determined using a cost-plus approach, whereby the Company estimates the cost to operate the vessel using cost benchmarking studies prepared by a third party, when available, or internal estimates when not available, plus a profit margin. The standalone selling price of the lease component has been determined using an adjusted market approach, whereby the Company calculates a rate excluding the operating component based on a market time-charter rate from published broker estimates, when available, or internal estimates when not available. Given that there are no observable standalone selling prices for either of these two components, judgment is required in determining the standalone selling price of each component. FPSO contracts and time charters Revenues from FPSO contracts and time charters accounted for as operating leases are recognized by the Company on a straight-line basis daily over the term of the contract. If collectability of the receipts from these contracts accounted for as operating leases is not probable, revenue that would have otherwise been recognized is limited to the amount collected from the charterer. The Company disposed of its last FPSO unit in October 2022. Upon commencement of an FPSO contract or time charter accounted for as a sales-type lease or direct financing lease, the carrying value of the vessel is derecognized and the net investment in the lease is recognized, based on the fair value of the vessel. For direct financing leases and sales-type leases, the lease element of time charter hire receipts is allocated to the lease receivable and revenues over the term of the lease using the effective interest rate method. The non-lease element of receipts is recognized by the Company on a straight-line basis daily over the term of the contract. Drydock cost reimbursements allocable to the non-lease element of a time-charter are recognized on a straight-line basis over the period between the previous scheduled dry dock and the next scheduled dry dock. In addition, if collectability of non-lease receipts of payments from a customer is not probable, any such receipts are recognized as a liability unless the receipts are non-refundable and either the contract has been terminated or the Company has no remaining performance obligations. The Company does not recognize revenues during days that the vessel is off-hire. When the FPSO contract or time charter contains a profit-sharing agreement, drydock cost reimbursements for time charters accounted for as operating leases, or other variable consideration, including performance-based metrics such as production tariffs and other operational performance measures, the Company recognizes this revenue in the period in which the changes in facts and circumstances on which the variable charter hire payments are based occur. In addition, performance-based revenue based on a multi-period performance-based metric that is allocable to non-lease services provided, is estimated and recognized over the performance period to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. Where the charterer is responsible for the operation of the vessel, the Company offsets any vessel operating expenses it incurs against reimbursements from the charterer. Voyage charters Revenues from voyage charters are recognized on a proportionate performance method. The Company uses a discharge-to-discharge basis in determining proportionate performance for all spot voyages that contain a lease and a load-to-discharge basis in determining proportionate performance for all spot voyages that do not contain a lease. The Company does not begin recognizing revenue until a charter has been agreed to by the customer and the Company, even if the vessel has discharged its cargo and is sailing to the anticipated load port on its next voyage. Revenues from the Company’s vessels performing voyage charters subject to revenue sharing agreements (or RSA s) follow the same revenue recognition policy as voyage charters not subject to RSAs. The difference between the net revenue earned by a vessel of the Company performing voyage charters subject to RSAs and its allocated share of the aggregate net contribution is reflected within voyage expenses. The consolidated balance sheets reflect in accrued revenue the accrued portion of revenues for those voyages that commence prior to the balance sheet date and complete after the balance sheet date. Voyage expenses incurred that are recoverable from the Company's customers in connection with its voyage charter contracts are reflected in voyage charter revenues and voyage expenses. Management fees and other Revenues are also earned from the management of third-party vessels. The Company recognizes fixed revenue on a straight-line basis over the duration of the management contract and variable revenue, such as monthly commissions, in the month they are earned. The Company presents the reimbursement of expenditures it incurs to provide the promised goods or services as revenue, if it controls such goods or services before they are transferred to the customer, and presents such reimbursement of expenditures as an offset against the expenditures, if the Company does not control the goods or services before they are transferred to the customer. Operating expenses Voyage expenses are all expenses unique to a particular voyage, including fuel expenses, port fees, cargo loading and unloading expenses, canal tolls, agency fees and commissions. In addition, the difference between the net revenue earned by a vessel of the Company performing voyage charters subject to an RSA and its allocated share of the aggregate net contribution is reflected within voyage expenses. The Company, as shipowner, pays voyage expenses under voyage charters. The Company’s customers pay voyage expenses under time charters, except when the vessel is off-hire during the term of a time charter in which case the Company pays voyage expenses. Vessel operating expenses include crewing, ship management services, repairs and maintenance, insurance, stores, lube oils and communication expenses. Voyage expenses and vessel operating expenses are recognized when incurred, except when the Company incurs pre-operational costs related to the repositioning of a vessel that relates directly to a specific customer contract, that generates or enhances resources of the Company that will be used in satisfying performance obligations in the future, whereby such costs are expected to be recovered via the customer contract. In this case, such costs are deferred and amortized over the duration of the customer contract. Cash and cash equivalents The Company classifies all highly liquid investments with an original maturity date of three months or less as cash and cash equivalents. Short-term investments The Company makes short-term investments which are comprised of short-term debt securities issued by the United States government and time deposits from financial institutions with a range of maturity dates up to twelve months from the origination date. The short-term debt securities and time deposits with initial maturity dates of more than three months, but less than or equal to twelve months from the origination date are classified as short-term investments on the consolidated balance sheets. The Company classifies these investments as held-to-maturity investments, which are carried at amortized cost. Restricted cash The Company maintains restricted cash deposits relating to certain forward freight agreements which are presented as current on the consolidated balance sheet (see Note 9). The Company maintains restricted cash deposits as required by the Company's obligations related to certain finance leases which are presented as non-current on the consolidated balance sheet (see Note 8). Accounts receivable and other loan receivables Accounts receivable are recorded at the invoiced amount and do not bear interest. The consolidated balance sheets reflect in accounts receivable, any amounts where the right to consideration is conditioned upon the passage of time, and, in accrued revenue, any accrued revenue where the right to consideration is conditioned upon something other than the passage of time. The Company’s advance to its equity-accounted joint venture is recorded at cost. Vessels and equipment All pre-delivery costs incurred during the construction of newbuildings, including interest, supervision and technical costs, are capitalized. The acquisition cost and all costs incurred to restore used vessels purchased by the Company to the standard required to properly service the Company’s customers are capitalized. Vessel capital modifications include the addition of new equipment or certain modifications to the vessel that are aimed at improving or increasing the operational efficiency and functionality of the asset. This type of expenditure is capitalized and depreciated over the estimated useful life of the modification. Expenditures covering recurring routine repairs and maintenance are expensed as incurred. Depreciation is calculated on a straight-line basis over a vessel’s estimated useful life, less an estimated residual value. Depreciation is calculated using an estimated useful life of 25 years for tankers carrying crude oil and refined product, commencing the date the vessel is delivered from the shipyard, or a shorter period if regulations prevent the Company from operating the vessels for 25 years. Depreciation of vessels and equipment, excluding amortization of dry-docking expenditures, for the years ended December 31, 2023, 2022 and 2021 aggregated $71.9 million, $71.9 million, and $78.5 million, respectively. Depreciation includes depreciation of all owned vessels and amortization of vessels accounted for as finance leases. Generally, the Company dry docks each oil tanker every two and a half years to five years The following table summarizes the change in the Company’s capitalized dry-docking costs from January 1, 2021 to December 31, 2023: Year Ended December 31, 2023 2022 2021 Balance at the beginning of the year 51,474 62,914 67,527 Costs incurred for dry dockings 15,483 15,792 23,042 Dry-dock amortization (25,245) (26,666) (27,123) Write-down / sales of vessels (1,139) (566) (532) Balance at the end of the year 40,573 51,474 62,914 Vessels and equipment that are intended to be held and used in the Company's business are assessed for impairment when events or circumstances indicate the carrying value of the asset may not be recoverable. The Company’s evaluation of events or circumstances that may indicate impairment, include, amongst others, an assessment of the intended use of the assets and anticipated operating cash flows, which is primarily influenced by the estimate of future charter rates for the vessels. The Company did not identify any indicators of impairment as of December 31, 2023, for its vessels. If the asset’s net carrying value exceeds the estimated net undiscounted cash flows expected to be generated over its remaining useful life, and the fair value of the asset is less than its carrying value, the carrying value of the asset is reduced to its estimated fair value. The estimated fair value for the Company’s impaired vessels is determined using discounted cash flows or appraised values. In cases where an active second-hand sale and purchase market does not exist, or in certain other cases, the Company uses a discounted cash flow approach to estimate the fair value of an impaired vessel. In cases where an active second-hand sale and purchase market exists, an appraised value is used to estimate the fair value of an impaired vessel. An appraised value is generally the amount the Company would expect to receive if it were to sell the vessel. Such appraisal is based on second-hand sale and purchase data, and other information provided by third parties. Vessels and equipment that are “held for sale” are measured at the lower of their carrying amount or fair value less costs to sell and are not depreciated while classified as held for sale. Interest and other expenses and related liabilities attributable to vessels and equipment classified as held for sale continue to be recognized as incurred. Bunker and lube oil inventory Bunker and lube oil inventory is stated at the lower of cost and net realizable value. Cost is determined on a first-in, first-out basis. Equity-accounted investments The Company’s investments in certain joint ventures and other partially-owned entities in which the Company does not control the entity but has the ability to exercise significant influence over the operating and financial policies of the entity are accounted for using the equity method of accounting. Under the equity method of accounting, investments are stated at initial cost and are adjusted for subsequent additional investments and the Company’s proportionate share of earnings or losses and distributions. The Company evaluates its equity-accounted for investments for impairment when events or circumstances indicate that the carrying value of such investments may have experienced an other-than-temporary decline in value below its carrying value. If an equity-accounted for investment experiences an other-than-temporary decline in value and if the estimated fair value is less than the carrying value, the carrying value is written down to its estimated fair value and the resulting impairment is recorded in the Company's consolidated statements of income (loss). Debt issuance costs Debt issuance costs related to a recognized debt liability, including fees, commissions, and legal expenses, are deferred and presented as a direct reduction from the carrying amount of that debt liability and amortized on an effective interest rate method over the term of the relevant loan. Debt issuance costs which are not attributable to a specific debt liability or where the debt issuance costs exceed the carrying value of the related debt liability (primarily undrawn revolving credit facilities) are deferred and presented as non-current assets in the Company's consolidated balance sheets. Amortization of debt issuance costs is included in interest expense in the Company's consolidated statements of income (loss). Fees paid to substantially amend a non-revolving credit facility are associated with the extinguishment of the old debt instrument and included in determining the debt extinguishment gain or loss to be recognized. Other costs incurred with third parties directly related to the extinguishment are deferred and presented as a direct reduction from the carrying amount of the replacement debt instrument and amortized using the effective interest rate method. In addition, any unamortized debt issuance costs associated with the old debt instrument are written off. If the amendment is considered not to be a substantial amendment, then the fees would be associated with the replacement or modified debt instrument and, along with any existing unamortized premium, discount and unamortized debt issuance costs, would be amortized as an adjustment of interest expense over the remaining term of the replacement or modified debt instrument using the effective interest method. Other related costs incurred with third parties directly related to the modification, other than the loan amendment fee, are expensed as incurred. Fees paid to amend a revolving credit facility are deferred and amortized over the term of the modified revolving credit facility. If the borrowing capacity of the revolving credit facility increases as a result of the amendment, unamortized debt issuance costs of the original revolving credit facility are amortized over the remaining term of the modified revolving credit facility. If the borrowing capacity of the revolving credit facility decreases as a result of the amendment, a proportionate amount, based on the reduction in borrowing capacity, of the unamortized debt issuance costs of the original revolving credit facility are written off and the remaining amount is amortized over the remaining term of the modified revolving credit facility. Credit losses The Company utilizes a lifetime expected credit loss measurement objective for the recognition of credit losses for net investments in direct financing and sales-type leases, loans to equity accounted joint ventures, guarantees of secured loan facilities of equity-accounted joint ventures, non-operating lease accounts receivable, contract assets and other receivables at the time the financial asset is originated or acquired. The expected credit losses are subsequently adjusted each period for changes in expected lifetime credit losses. The Company discontinues accrual of interest on financial assets if collection of required payments is no longer probable, and in those situations, recognizes payments received on non-accrual assets on a cash basis method, until collection of required payments becomes probable. The Company considers a financial asset to be past due when payment is not made with 30 days of it being owed, assuming there is no dispute or other uncertainty regarding the amount owing. Expected credit loss provisions are presented on the consolidated balance sheets as a reduction to the carrying value of the related financial asset and as an other long-term liability for expected credit loss provisions that relate to guarantees of secured loan facilities of equity-accounted joint ventures. Changes in expected credit loss provisions are presented within other - net within the consolidated statements of income (loss). For charter contracts being accounted for as operating leases, if the remaining lease payments are no longer probable of being collected, any unpaid accounts receivable and any accrued revenue will be reversed against revenue and any subsequent payments will be recognized as revenue when collected until such time that the remaining lease payments are probable of being collected. Derivative instruments All derivative instruments are initially recorded at fair value as either assets or liabilities in the accompanying consolidated balance sheets and subsequently remeasured to fair value each period end, regardless of the purpose or intent for holding the derivative. The method of recognizing the resulting gain or loss is dependent on whether the derivative contract is designed to hedge a specific risk and whether the contract qualifies for hedge accounting. The Company does not apply hedge accounting to its derivative instruments, except for certain types of interest rate swaps designated as cash flow hedges, which are included in discontinued operations. When a derivative is designated as a cash flow hedge, the Company formally documents the relationship between the derivative and the hedged item. This documentation includes the strategy and risk management objective for undertaking the hedge and the method that will be used to assess the effectiveness of the hedge. Any gains and losses on the derivative that are excluded from the assessment of hedge effectiveness are recognized immediately in earnings. The Company does not apply hedge accounting if it is determined that the hedge is not effective or will no longer be effective, the derivative is sold or exercised, or the hedged item is sold, repaid or no longer probable of occurring. For derivative financial instruments designated and qualifying as cash flow hedges, changes in the fair value of the derivative financial instruments are initially recorded as a component of accumulated other comprehensive loss in total equity. In the periods when the hedged items affect earnings, the associated fair value changes on the hedging derivatives are transferred from total equity to the corresponding earnings line item (e.g. interest expense) in the Company's consolidated statements of income (loss). If a cash flow hedge is terminated or de-designated and the originally hedged item is still considered probable of occurring, the gains and losses initially recognized in total equity remain there until the hedged item impacts earnings, at which point they are transferred to the corresponding earnings line item in the Company's consolidated statements of income (loss). If the hedged items are no longer probable of occurring, amounts recognized in total equity are immediately transferred to the corresponding earnings line item in the Company's consolidated statements of income (loss). For derivative financial instruments that are not designated or that do not qualify as hedges under Financial Accounting Standards Board (or FASB ) Accounting Standards Codification (or ASC ) 815, Derivatives and Hedging , changes in the fair value of the derivative financial instruments are recognized in earnings. Gains and losses from the Company’s non-designated interest rate swaps related to long-term debt, non-designated bunker fuel swap contracts and forward freight agreements, and non-designated foreign currency forward contracts are recorded in realized and unrealized gains (losses) on non-designated derivative instruments in the Company's consolidated statements of income (loss). Gains and losses from the Company’s non-designated cross currency swaps are recorded in income from discontinued operations in the Company's consolidated statements of income (loss). Goodwill and intangible assets Goodwill is not amortized but is reviewed for impairment at the reporting unit level on an annual basis or more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. A reporting unit is a component of the Company that constitutes a business for which discrete financial information is available and regularly reviewed by management. When goodwill is reviewed for impairment, the Company may elect to assess qualitative factors to determine whether it is more likely t |
