Financial Statements	1
Management’s Discussion and Analysis of Financial Condition and Results of Operations	38

Unless we otherwise specify, when used in this Report, the terms “Seaspan”, the “Company”, “we”, “our” and “us” refer to Seaspan Corporation and its subsidiaries.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholder and Board of Directors of Seaspan Corporation:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Seaspan Corporation (the “Company”) as of December 31, 2024 and 2023, the related consolidated statements of operations, comprehensive income, shareholder’s equity and cash flows for each of the years in the three‑year period ended December 31, 2024, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the years in the three‑year period ended December 31, 2024, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidatedfinancial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Assessment of indicators of impairment for vessels

As discussed in Note 2(e) to the consolidated financial statements, vessels that are held for are evaluated for impairment when events or circumstances indicate that their carrying amounts may not be recoverable from future undiscounted cash flows. Examples of such events or changes in circumstances for vessels (“impairment indicators”) include, among others, a significant adverse change in the extent or manner in which the asset is being used or in its physical condition; a significant adverse change in legal factors or in the business climate that could affect the asset’s value, including an adverse action or assessment by a foreign government that impacts the use of the asset; or a current-period operating or cash flow loss combined with a history of operating or cash flow losses, or a projection or forecast that demonstrates continuing losses associated with the asset’s use. The determination of whether impairment indicators exist requires significant judgment in evaluating underlying significant assumptions including charter rates, utilization rates, operating costs and current vessel market values. The Company has not identified any events or changes in circumstances indicating that the carrying amount of the assets may not be recoverable for the year ended December 31, 2024. As discussed in Note 5 and Note 6, the total carrying value of the Company’s vessels, including right-of-use vessels, was $12,237.6 million as of December 31, 2024.

We identified the assessment of indicators of impairment for vessels as a critical audit matter. A higher degree of subjective auditor judgment was required to assess the Company’s determination of whether an indicator of impairment existed, based

1

on the Company’s evaluation of the significant assumptions. Changes in these significant assumptions could have changed the Company’s conclusion that no indicators of impairment were identified.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of an internal control over the Company’s impairment indicator assessment process related to the identification and evaluation of indicators of impairment and underlying significant assumptions. We evaluated significant assumptions used in the Company’s evaluation by comparing current charter rates to existing customer contracts and estimates of future charter rates to third-party industry publications for vessels with similar characteristics. We evaluated the Company’s anticipated future utilization rates and operating costs assumptions by comparing to the Company’s historical utilization rates and operating costs including impacts of inflation. For utilization rates, we also compared anticipated supply and demand conditions that would impact utilization to third party industry publications. We evaluated the Company’s assessment of current market values of vessels by comparing to recent vessel purchases and third-party industry publications.

Years ended December 31, 2024, 2023 and 2022

1.General:

Seaspan Corporation (“Seaspan” or the “Company”) was incorporated on May 3, 2005 in the Marshall Islands and owns and operates containerships pursuant to primarily long-term, fixed-rate time charters to major container liner companies. Seaspan is a wholly owned subsidiary of Atlas Corp. ("Atlas").

On March 28, 2023, pursuant to an Agreement and Plan of Merger (the “Merger Agreement”), dated as of October 31, 2022, by and among Atlas, Poseidon Acquisition Corp. (since renamed Poseidon Corp., “Poseidon”), an entity formed by certain affiliates of Fairfax Financial Holdings Limited (“Fairfax”), certain affiliates of the Washington Family (“Washington”), David Sokol, Chairman of the Board of Directors of the Company (the “Chairman”), Ocean Network Express Pte. Ltd., (“ONE”) and certain of their respective affiliates, and Poseidon Merger Sub, Inc., a wholly-owned subsidiary of Poseidon (“Merger Sub”), Merger Sub merged with and into Atlas with Atlas continuing as the surviving corporation and a wholly-owned subsidiary of Poseidon (other than with respect to Atlas’ preferred shares) (the “Merger”). Each common share outstanding prior to the Merger, other than common shares contributed to Poseidon immediately prior to the consummation of the Merger by Fairfax, Washington, the Chairman and the chief executive officer, were converted into the right to receive $15.50 per common share in cash.

2.Significant accounting policies:

(a)Basis of presentation:

These consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America and the following accounting policies have been consistently applied in the preparation of the consolidated financial statements.

(b)Principles of consolidation:

The accompanying consolidated financial statements include the accounts of Seaspan Corporation and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated upon consolidation.

The Company also consolidates any variable interest entities (“VIEs”) of which it is the primary beneficiary. The primary beneficiary is the enterprise that has both the power to make decisions that most significantly affect the economic performance of the VIE and has the right to receive benefits or the obligation to absorb losses that in either case could potentially be significant to the VIE. The impact of the consolidation of these VIEs is described innote 11.

The Company accounts for its investment in companies in which it has significant influence by the equity method. The Company’s proportionate share of earnings is included in earnings and added to or deducted from the cost of the investment.

(c)Foreign currency translation:

The functional and reporting currency of the Company is the United States dollar. Transactions involving other currencies are converted into United States 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 United States dollar are translated into United States dollars using exchange rates at that date. Exchange gains and losses are included in net earnings.

(d)Cash equivalents:

Cash equivalents include highly liquid securities with terms to maturity of three months or less when acquired.

Years Ended December 31, 2024, 2023 and 2022

2. Significant accounting policies (continued):

(e)Vessels:

Except as described below, vessels are recorded at their cost, which consists of the purchase price, acquisition and delivery costs, less accumulated depreciation.

Vessels purchased from the Company’s predecessor upon completion of the Company’s initial public offering in 2005 were initially recorded at the predecessor’s carrying value.

Vessels under construction include deposits, installment payments, interest, financing costs, transaction fees, construction design, supervision costs, and other pre-delivery costs incurred during the construction period.

Depreciation is calculated on a straight-line basis over the estimated useful life of each vessel, which is 30 years from the date of completion. The Company calculates depreciation based on the estimated remaining useful life and the expected salvage value of the vessel.

Vessels that are held for use are evaluated for impairment when events or circumstances indicate that their carrying amounts may not be recoverable from future undiscounted cash flows. Such evaluations include the comparison of current and anticipated operating cash flows, assessment of future operations and other relevant factors. If the carrying amount of the vessel exceeds the estimated net undiscounted future cash flows expected to be generated over the vessel’s remaining useful life, the carrying amount of the vessel is reduced to its estimated fair value.

(f)Dry-dock activities:

Classification society rules require that vessels be dry-docked for inspection including planned major maintenance and overhaul activities for ongoing certification. The Company generally dry-docks its vessels once every five years. Dry-docking activities include the inspection, refurbishment and replacement of steel, engine components, electrical, pipes and valves, and other parts of the vessel. The Company uses the deferral method of accounting for dry-dock activities whereby capital costs incurred are deferred and amortized on a straight-line basis over the period until the next scheduled dry-dock activity.

(g)Goodwill:

Goodwill represents the excess of the purchase price of an acquired enterprise over the fair value assigned to assets acquired and liabilities assumed in a business combination. Goodwill is not amortized, but reviewed for impairment annually or more frequently if impairment indicators arise. When goodwill is reviewed for impairment, the Company may elect to assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. Alternatively, the Company may bypass this step and use a fair value approach to identify potential goodwill impairment and, when necessary, measure the amount of impairment. The Company uses a discounted cash flow model to determine the fair value of reporting units, unless there is a readily determinable fair market value.

(h)Deferred financing fees:

Deferred financing fees represent the unamortized costs incurred on issuance of the Company’s credit facilities and other financing arrangements and are presented as a direct deduction from the related debt liability when available. Amortization of deferred financing fees on credit facilities is provided on the effective interest rate method over the term of the facility based on amounts available under the facilities. Amortization of deferred financing fees on other financing arrangements is provided on the effective interest rate method over the term of the underlying obligation. Amortization of deferred financing fees is recorded as interest expense.

2. Significant accounting policies (continued):

(i)Revenue:

The Company derives its revenue primarily from the charter of its vessels. Each charter agreement is evaluated and classified as an operating lease or financing lease based on the lease term, fair value associated with the lease and any purchase options or obligations. The assessment is done at lease commencement and reassessed only when a modification occurs that is not considered a separate contract.

Charters classified as operating leases include a lease component associated with the use of the vessel and a non-lease component related to vessel management. Total consideration in the lease agreement is allocated between the lease and non-lease components based on their relative standalone selling prices. For arrangements where the timing and pattern of transfer to the lessee is consistent between the lease and non-lease components and the lease component, if accounted for separately, would be classified as an operating lease, the Company has elected to treat the lease and non-lease components as a single lease component. Revenue is recognized each day the vessels are on-hire, managed and performance obligations are satisfied.

For charters that are classified as direct financing leases or sales-type leases, the present value of minimum lease payments and any unguaranteed residual value are recognized as net investment in lease. The discount rate used in determining the present values is the interest rate implicit in the lease. The lower of the fair value of the vessel based on information available at lease commencement date and the present value of the minimum lease payments computed using the interest rate implicit specific to each lease, represents the price, from which the carrying value of the vessel and any initial direct costs are deducted in order to determine the selling profit or loss.

For financing leases that are classified as direct financing leases, the unearned lease interest income including any selling profit and initial direct costs are deferred and amortized to income over the period of the lease so as to produce a constant periodic rate of return on the net investment in lease. Any selling loss is recognized at lease commencement date.

For financing leases that are classified as sales-type leases, any selling profit or loss is recognized at lease commencement date. Initial direct costs are expensed at lease commencement date if the fair value of the vessel is lower from its carrying amount. If the fair value of the vessel is equal to its carrying amount, initial direct costs are deferred and amortized to income over the term of the lease.

(j)Leases:

Leases classified as operating leases are recorded as lease liabilities based on the present value of minimum lease payments over the lease term, discounted using the lessor’s rate implicit in the lease for each individual lease arrangement or the Company’s incremental borrowing rate, if the lessor’s implicit rate is not readily determinable. The lease term includes all periods covered by renewal and termination options where the Company is reasonably certain to exercise the renewal options or not to exercise the termination options. Corresponding right-of-use assets are recognized consisting of the lease liabilities, initial direct costs and any lease incentive payments.

Lease liabilities are drawn down as lease payments are made and right-of-use assets are depreciated over the term of the lease. Operating lease expenses are recognized on a straight-line basis over the term of the lease, consisting of interest accrued on the lease liability and depreciation of the right-of-use asset, adjusted for changes in index-based variable lease payments in the period of change.

Lease payments on short-term operating leases with lease terms of 12 months or less are expensed as incurred.

Transactions are accounted for as sale-leaseback transactions when control of the vessel is transferred. For sale-leaseback transactions, where the Company is the seller-lessee, any gains or losses on sale are recognized upon transfer.

2. Significant accounting policies (continued):

(k)Derivative financial instruments:

From time to time, the Company utilizes derivative financial instruments. All of the Company’s derivatives are measured at their fair value at the end of each period. Derivatives that mature within one year are classified as current. For derivatives not designated as accounting hedges, changes in their fair value are recorded in earnings.

The Company’s hedging policies permit the use of various derivative financial instruments to manage interest rate risk.

The Company had previously designated certain of its interest rate swaps as accounting hedges and applied hedge accounting to those instruments. By September 30, 2008, the Company de-designated all of the interest rate swaps it had accounted for as hedges to that date. Subsequent to their de-designation dates, changes in their fair value are recorded in earnings.

(l)     Fair value measurement:

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e. the “exit price”) in an orderly transaction between market participants at the measurement date. The hierarchy is broken down into three levels based on the observability of inputs as follows:

•Level 1 — Valuations based on quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. Valuation adjustments and block discounts are not applied to Level 1 instruments. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these products does not entail a significant degree of judgment.

•Level 2 — Valuations based on one or more quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly.

•Level 3 — Valuations based on inputs that are unobservable and significant to the overall fair value measurement.

(m)     Share-based compensation:

The Company granted phantom share units, restricted shares, restricted stock units and stock options to certain of its officers, members of management and directors as compensation. Compensation cost was measured at the grant date fair values as follows:

•Restricted shares, phantom share units and restricted stock units were measured based on the quoted market price of the Company’s common shares on the date of the grant.

•Stock options were measured at fair value using the Black-Scholes model.

The fair value of each grant is recognized on a straight-line basis over the requisite service period. The Company accounts for forfeitures in share-based compensation expense as they occur. If share compensation arrangements are amended such that they are considered an accounting modification, the Company determines whether there is a change in accounting classification and whether any additional compensation cost should be recognized. Liability based arrangements are re-measured at fair value each reporting period until settlement.

2. Significant accounting policies (continued):

(n) Use of estimates:

The preparation of consolidated financial statements requires management to make estimates and assumptions that affect the:

•reported amounts of assets and liabilities,

•disclosure of contingent assets and liabilities at the balance sheet dates and

•reported amounts of revenue and expenses during the reporting fiscal periods.

Areas where accounting judgments and estimates are significant to the Company and where actual results could differ from those estimates, include the:

•assessment of vessel useful lives;

•expected vessel salvage values;

•recoverability of the carrying value of vessels which are subject to future market events;

•carrying value of goodwill; and

•fair value of interest rate swaps, other derivative financial instruments.

(o)    Recent accounting pronouncements:

Discontinuation of LIBOR

The Company adopted ASU 2020-04, “Reference Rate Reform (Topic 848)”, prospectively to contract modifications. The guidance provides optional relief for the discontinuation of LIBOR resulting from rate reform. Contract terms that are modified due to the replacement of a reference rate are not required to be remeasured or reassessed under FASB’s relevant U.S. GAAP Topic. The election is available by Topic. The Company has elected to apply the optional relief for contracts under ASC 470, “Debt”, ASC 840 and 842, “Leases”, and ASC 815, “Derivatives and Hedging”. There was no impact to the Company’s financial statements upon initial adoption. The LIBOR replacement modifications for Debt contracts will be accounted for by prospectively adjusting the effective interest rate in the agreements. Existing lease and derivative contracts will require no reassessments. Transition activities are focused on the conversion of existing LIBOR based contracts to the Secured Overnight Financing Rate (“SOFR”).

Debt with conversion and other options

Effective January 1, 2022, the Company adopted ASU 2020-06, “Debt – Debt with Conversion and Other Options (Subtopic 470-20)” (“ASU 2020-06”), using the modified retrospective method, whereby the cumulative effect adjustment was made as of the date of the initial application. Accordingly, financial information and disclosures in the comparative period were not restated. The impact of the adoption of ASU 2020-06 resulted in an adjustment of $5,073,000 to opening retained earnings at January 1, 2022 related to the unamortized debt discount that was initially recorded when the convertible notes were issued. Under ASU 2020-06, the accounting for convertible debt instruments is simplified by reducing the number of accounting models and circumstances when embedded conversion features are separately recognized.

(p)    Recent accounting pronouncements not yet adopted:

In December 2023, the Financial Accounting Standards Board (“FASB”) issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 is intended to improve the transparency of income tax disclosures and includes enhanced requirements on the rate reconciliation, including specific categories that must be disclosed, and provides a threshold over which reconciling items must be disclosed. The amendments in the update also require annual disclosure of income taxes paid, disaggregated by federal, state, and foreign taxes, as well as any individual jurisdictions in which income taxes paid is greater than 5% of total income taxes paid. This is effective for annual periods beginning after December 15, 2024 and should be applied prospectively although retrospective application is permitted. The Company is evaluating the guidance to determine the impact it will have on its consolidated financial statements.

In November 2024, FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (“ASU 2024-03”). The ASU requires entities to disclose the amounts of purchases of inventory, employee compensation, depreciation and intangible asset amortization included in each relevant expense caption; as well as a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively. The amendment also requires disclosure of the total amount of selling expense and, in annual reporting periods, an entity’s definition of selling expenses. The ASU is effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027 and early adoption is permitted. The requirements will be applied prospectively with the option for retrospective application. The Company is evaluating the guidance to determine the impact it will have on its consolidated financial statements.

As a result, the remaining term loan credit financing available for the remaining one vessel is $78,031,000, which is undrawn as of December 31, 2024.In March 2023, the Company entered into amended and restated senior secured loan facilities which (i) increased the commitments under the bank loan facilities by $250,000,000, of which $200,000,000 was drawn immediately and $50,000,000 of which was drawn in September 30, 2023, (ii) increased the amount of total borrowing permitted relative to total assets from 65% to 75%, (iii) replaced the LIBOR with SOFR as the reference interest rate, and (iv) extended the maturities of tranches due in 2026 and 2027 by approximately two years.

Term loan credit facilities drawn mature between March 3, 2028 and January 21, 2030.

For the Company’s floating rate term loan credit facilities, interest is calculated based on three month or six month SOFR, plus a margin per annum, dependent on the interest period selected by the Company. The three month and six month average SOFR was 4.5% and 5.1%, respectively (2023 – 5.4% and 5.4%, respectively) and the margins ranged between 1.91% and 2.43% as at December 31, 2024 (2023 – 1.93% and 2.43%).

The Company is subject to commitment fees at 0.49% (2023 – 0.44% and 0.49%) calculated on the undrawn amounts under the various facilities.

The weighted average rate of interest, including the applicable margin, was 6.5% at December 31, 2024 (2023 – 7.4%) for term loan credit facilities. Interest payments are made in monthly, quarterly or semi-annual payments.

Principal repayments under term loan credit facilities are made in quarterly or semi-annual payments. For those related to newbuild containerships, payments commence three, six or thirty-six months after delivery of the associated newbuild containership, utilization date or the inception date of the term loan credit facilities.

(d)Credit facilities - other:

As of December 31, 2024, the Company’s credit facilities were secured by first-priority mortgages granted on 50 of its vessels, together with other related security. The security for each of the Company’s current secured credit facilities may include:

•A first priority mortgage on the collateral vessels funded by the related credit facility;

•An assignment of the Company’s time charters and earnings related to the related collateral vessels;

•An assignment of the insurance on each of the vessels that are subject to a related mortgage;

•An assignment of the Company’s related shipbuilding contracts and the corresponding refund guarantees;

•A pledge over shares of various subsidiaries; and

•A pledge over the related retention accounts.

As at December 31, 2024, $1,423,284,000 principal amount of indebtedness under the Company’s term loan and revolving credit facilities, together with $1,000,000,000 of sustainability-linked, senior secured notes with maturities from June 2031 to September 2037, was secured by a portfolio of 48 vessels, the composition of which can be changed and is subject to a borrowing base and portfolio concentration requirements, as well as compliance with financial covenants and certain negative covenants.

The Company may prepay certain amounts outstanding without penalty, other than breakage costs in certain circumstances. A prepayment may be required as a result of certain events, including without limitation the sale or loss of a vessel, a termination or expiration of a charter (and the inability to enter into a replacement charter acceptable to lenders within a prescribed period of time). The amount that must be prepaid may be calculated based on the loan to market value. In these circumstances, valuations of the Company’s vessels are conducted on a “without charter” basis as required under the credit facility agreement.

Each credit facility contains a mix of financial covenants requiring the Company to maintain minimum liquidity, tangible net worth, interest and principal coverage ratios and/or debt to assets ratios, as defined.

Certain facilities are guaranteed by an intermediate parent entity, in which case the parent entity must meet certain consolidated financial covenants under those term loan facilities including maintaining certain minimum tangible net worth, cash requirements and debt-to-asset ratios.

Some of the facilities also have an interest and principal coverage ratio, debt service coverage and vessel value requirement for the subsidiary borrower. The Company was in compliance with these covenants as at December 31, 2024.

(e)Senior unsecured notes:

In February 2021, the Company issued $200,000,000 of 6.5% senior unsecured sustainability-linked bonds in the Nordic bond market (“2024 Bonds”). In April 2021, the Company issued a further $300,000,000 of senior unsecured sustainability-linked bonds in the Nordic bond market (the “2026 Bonds” and together with the 2024 Bonds, the “Bonds”). The Bonds were to mature in February 2024 and April 2026, respectively, and bear interest at 6.5% per annum. If the sustainability performance targets are not met during the term of the Bonds, the Bonds will be settled at maturity at 100.5% of the initial principal. The Bonds are listed on the Oslo Stock Exchange.

As a result of the Merger (note 1), Atlas’ common shares were de-listed on April 10, 2023 (the “De-listing”). The Company had notified the holders of the 6.5% senior unsecured sustainability-linked bonds due 2024 (the “2024 NOK Bonds”) and the 6.5% senior unsecured sustainability-linked bonds due 2026 (the “2026 NOK Bonds”) of this de-listing event and that each holder of the 2024 NOK Bonds and the 2026 NOK Bonds had a right to require the Company to purchase all or some of the bonds held by such holder (a “NOK Put Option”) at a price equal to 101% of the principal amount plus accrued interest. Each holder could exercise a NOK Put Option during the exercise period which ended on May 3, 2023.

On May 10, 2023, the Company repurchased $179,400,000 of 2024 NOK Bonds and $294,900,000 of the 2026 NOK Bonds. In each case, the Company purchased 2024 and 2026 NOK Bonds from holders who exercised their NOK Put Options, at a purchase price equal to 101% of the principal amount plus accrued interest for a total payment of $482,706,000. The remaining 2024 NOK Bonds totaling $20,600,000 matured on February 5, 2024. On May 22, 2023, as a result of having repurchased more than 90% of the outstanding 2026 NOK Bonds, the Company exercised its option to repurchase all remaining outstanding 2024 and 2026 NOK Bonds from holders. The repurchase, representing a payment of $25,700,000, occurred on February 5, 2024.

On July 14 2021, the Company issued $750,000,000 of senior unsecured notes. These notes mature in 2029 and accrue interest at 5.5% per annum, payable semi-annually beginning on February 1, 2022. The notes are a blue transition bond developed to further the Company’s sustainability efforts.

(f)Senior unsecured exchangeable notes:

On December 21, 2020, the Company issued $201,250,000 aggregate principal amount of 3.75% exchangeable senior unsecured notes due 2025 (the “Exchangeable Notes”) in a private placement.

The holders may require Atlas to redeem the Exchangeable Notes held by them upon the occurrence of certain corporate events qualifying as a fundamental change in the business. The Merger (note 1) and subsequent de-listing of Atlas’ common shares on April 10, 2023 constituted a “Make-Whole Fundamental Change” under the terms of the Exchangeable Notes. On March 28, 2023, the Company entered into a supplemental indenture providing the holders of the Exchangeable Notes the right to exchange each $1,000 principal amount of such Exchangeable Note into a number of units based on a defined exchange rate. In connection with the Make-Whole Fundamental Change, each holder had the right, at its option, to exchange all or any portion of its Exchangeable Notes at any time from during the make-whole exchange period at an increased exchange rate on account of a Make-Whole Fundamental Change. During the make-whole exchange period, which ended on May 22, 2023, all of the outstanding Exchangeable Notes were exchanged by the Holders representing a total settlement of $253,139,000

Capped Call Transactions

In connection with the issuance of the Exchangeable Notes, the Company entered into capped call transactions with affiliates of certain of the initial purchasers of the Exchangeable Notes and other financial institutions, using $15,536,000 in proceeds from the issuance, to reduce the potential dilution to Atlas common shares upon any exchange of notes and/or offset any cash payments the Company was required to make upon exchange of the Exchangeable Notes, in excess of the principal amount. They may have been settled in cash, shares, or a combination of cash and shares as determined by the settlement method of the Exchangeable Notes, at a strike price with underlying shares equal to that of the Exchangeable Notes and subject to anti-dilution adjustments substantially similar to those applicable to the Exchangeable Notes. The capped calls were exercisable up to a maximum price of $17.85 per share, subject to certain adjustments. The instruments were to expire on December 15, 2025. In connection with the exchange of the Exchangeable Notes, the Company terminated all capped call transactions entered into concurrently with the issue of Exchangeable Notes.

The Company, through certain of its wholly-owned subsidiaries, has entered into non-recourse or limited recourse sale-leaseback arrangements with financial institutions to fund the acquisition of vessels.

Under these arrangements, the Company has agreed to transfer the vessels to the counterparties and lease the vessels back from the counterparties over the applicable lease term as a financing lease arrangement. In the arrangements where the shipbuilding contracts are novated to the counterparties, the counterparties assume responsibility for the remaining payments under the shipbuilding contracts.

In certain of the arrangements, the counterparties are companies whose only assets and operations are to hold the Company’s leases and vessels. The Company operates the vessels during the lease term, supervises the vessels’ construction before the lease term begins, if applicable, and/or is required to purchase the vessels from the counterparties at the end of the lease term. As a result, in most cases, the Company is considered to be the primary beneficiary of the counterparties and consolidates the counterparties for financial reporting purposes. In all cases, these arrangements are considered failed-sales. The vessels are recorded as an asset and the obligations under these arrangements are recorded as a liability. The terms of the leases are as follows:

(i) European Union Emissions Trading System (“EU ETS):

As of January 1, 2024, the European Union expanded the existing EU ETS to the shipping industry. Under the EU ETS requirements, the Company acquires European Union allowances (“EUAs”) related to greenhouse gas emissions from its vessels that travel to, from, and within the European Union and European Economic geographic regions.

The Company has recorded a liability related to its emissions level for the year-ended December 31, 2024 as part of other accrued liabilities. If the Company has insufficient EUAs to cover emissions of its vessels, an accrual representing this emissions liability is recorded based on the fair market value of an EUA that is traded on a regulated energy exchange at the end of the reporting period. The measurement of the obligation is determined on a first-in, first-out method based on the cost of the EUAs that are acquired by the Company. The Company is required to surrender EUAs through its Union Registry account on September 30, 2025 to cover its vessels' annual emissions for the year ending December 31, 2024. The Company has recognized a corresponding receivable as the amounts incurred will be recovered from its customers

(a)Fair value:

The following table includes the estimated fair value and carrying value of those assets and liabilities that are measured at fair value on a recurring basis(1):

		December 31, 2024				December 31, 2023
	Fair Value Hierarchy Level	Carrying Amount (Liability)		Fair Value (Liability)		Carrying Amount (Liability)		Fair Value (Liability)
Term loan & revolver (note 8)	Level 2	$	(1,071.7)	$	(1,086.9)	$	(1,495.6)	$	(1,498.1)
Senior unsecured notes - public (note 8)	Level 1	(750.0)		(703.6)		(775.7)		(665.3)
Senior secured notes - non-public (note 8)	Level 2	(1,000.0)		(1,008.1)		(1,000.0)		(989.7)
Other financing arrangements (note 11)	Level 2	(7,751.8)		(7,820.6)		(4,656.5)		(4,591.2)

(1)The carrying values and fair values presented above are exclusive of deferred financing fees.

The carrying values of cash and cash equivalents, short-term investments, accounts receivable, accounts payable and accrued liabilities approximate their fair values because of their short term to maturity.

The fair value of the term loan, revolving credit facilities, senior secured notes and other financing arrangements, are estimated based on expected principal repayments and interest, discounted by relevant forward rates plus a margin appropriate to the credit risk of the Company. Therefore, the Company has categorized the fair value of these financial instruments as Level 2 in the fair value hierarchy.

The fair value of the Company’s senior unsecured notes, is calculated using observable inputs such as quoted prices in active markets. As a result, these amounts are categorized as Level 1 in the fair value hierarchy.

The Company’s interest rate derivative financial instruments are re-measured to fair value at the end of each reporting period. The fair values of the interest rate derivative financial instruments have been calculated by discounting the future cash flow of both the fixed rate and variable rate interest rate payments. The discount rate was derived from a yield curve created by nationally recognized financial institutions adjusted for the associated credit risk. The fair values of the interest rate derivative financial instruments are determined based on inputs that are readily available in public markets or can be derived from information available in publicly quoted markets. Therefore, the Company has categorized the fair value of these derivative financial instruments as Level 2 in the fair value hierarchy.

ITEM 2 - MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

The following should be read in conjunction with the audited consolidated financial statements and related notes included in this Report and the Atlas Corp. audited consolidated financial statements and related notes for the year ended December 31, 2024 filed with the U.S. Securities and Exchange Commission on an Atlas Corp. Form 20-F. Unless otherwise indicated, all amounts are presented in U.S. dollars, or USD. We prepare our consolidated financial statements in accordance with U.S. GAAP.

Overview

General

Seaspan was incorporated on May 3, 2005, in the Republic of the Marshall Islands. Seaspan is a leading independent charter owner and manager of containerships, which we charter primarily pursuant to long-term, fixed-rate time charters with nine major container liner companies. We primarily deploy our vessels on long-term, fixed-rate time charters to take advantage of the stable cash flow and high utilization rates that are typically associated with long-term time charters. As of December 31, 2024, we operated a fleet of 186 vessels that have an average age of approximately seven years, on a TEU weighted basis. As at December 31, 2024, we have 37 newbuild vessels under construction delivering through to August 2029.

Our primary objective for Seaspan is to continue to grow our containership leasing business through accretive vessel acquisitions as market conditions allow. Most of our customers’ containership business revenues are derived from the shipment of goods from the Asia Pacific region to various overseas export markets in the United States and in Europe.

We use the term “twenty-foot equivalent unit”, or TEU, the international standard measure of containers, in describing the capacity of our containerships, which are also referred to as our “vessels”.

The following table summarizes key facts regarding Seaspan’s 186 fleet as of December 31, 2024:

Financial Results Summary

Revenue

Revenue increased by 34.8% to $2,311.5 million for the year ended December 31, 2024 compared to 2023. The increase is largely driven by delivery of 35 newbuild vessels in the current year and a full year impact of 22 newbuild deliveries from 2023, offset by two vessel sales during the year.

Operating Expense

Operating expense increased by 21.4% to $421.7 million for the year ended December 31, 2024 compared to 2023. The increase was primarily due to growth in our fleet due to newbuild deliveries throughout 2024, and a full year impact of the newbuild deliveries in 2023.

Depreciation and Amortization Expense

Depreciation and amortization expense increased by 35.4% to $508.0 million for the year ended December 31, 2024 compared to 2023. The increase was primarily due to newbuild vessels delivered throughout 2024, a full year impact of vessels delivered in 2023, offset by the impact of two vessel sales in the year.

General and Administrative Expense

General and administrative expense decreased by 4.5% to $55.4 million for the year ended December 31, 2024 compared to 2023. The decrease was primarily due to a decrease in general corporate expenses including non-cash share-based compensation and expenses related to the Merger transaction in 2023.

Operating Lease Expense

Operating lease expense decreased by 51.7% to $56.4 million for the year ended December 31, 2024 compared to 2023. The decrease was primarily due to a lease reclassification from operating to financing as a result of pre-existing purchase options being exercised in the year.

Interest Expense and Amortization of Deferred Financing Fees

Interest expense increased by 73.5% to $632.4 million for the year ended December 31, 2024 compared to 2023 primarily due to higher interest rates and higher balances related to other financing arrangements from vessel deliveries.

Gain on Derivative Instruments

The change in fair value of derivative instruments resulted in a gain of $44.6 million for the year ended December 31, 2024.The gains for these periods were primarily due to an increase in the forward curve of the benchmark rates and offset by swap settlements. Based on current notional amount and tenor of our interest rate swap portfolio, a one percent parallel shift in the overall yield curves is expected to result in a change in the fair value of our interest rate swaps of approximately $44.5 million.

Our fair value instruments, including interest rate swaps were marked to market with all changes in the fair value of these instruments recorded in “Change in fair value of financial instruments” in our Consolidated Statement of Operations.

Liquidity and Capital Resources

Liquidity

As of December 31, 2024, we have total liquidity of $1,457.4 million, consisting of $757.4 million of cash and cash equivalents and $700.0 million of undrawn commitments under available revolving credit facilities. Our primary short-term liquidity needs are to fund our operating expenses, investments in assets including vessels under construction, debt repayments, lease payments, swap settlements, payment of quarterly dividends and payments on our other financing arrangements. Our medium-term liquidity needs primarily relate to debt repayments, vessel purchase commitments, lease payments and payments on our other financing arrangements. Our long-term liquidity needs primarily relate to potential future acquisitions, lease payments, debt repayments including repayment of our notes, the potential future redemption of Atlas’ preferred shares and payments on our other financing arrangements. Please read note 8 “Long-term debt”, note 9 “Operating lease liabilities”, note 10 “Finance lease liabilities”, and note 11 “Other financing arrangements” in our year ended Consolidated Financial Statements for additional information.

We anticipate that our primary sources of funds for our short-term liquidity needs will be cash from operations, and existing and new credit facilities and other financing arrangements. We anticipate our medium and long-term sources of funds will be from cash from operations, new credit facilities, lease facilities and capital markets financings to the extent available.

The following table summarizes our liquidity as of December 31, 2024 and 2023:

	December 31,				Change
(in millions of US dollars)	2024		2023		$		%
Cash and cash equivalents	$	757.4	$	228.9	$	528.5	231	%
Undrawn revolving credit facilities	700.0		330.0		370.0		112	%
Total liquidity	1,457.4		558.9		898.5		161	%
Total committed and undrawn newbuild financings(1)	1,496.5		3,334.6		(1,838.1)		(55)	%
Total liquidity including newbuild financings	$	2,953.9	$	3,893.5	$	(939.6)	(24)	%

(1)The $1,496.5 million and $3,334.6 million represents amounts that have been secured for the Company’s newbuild financings and amounts are available to be drawn as construction milestones are completed. As at December 31, 2024 and December 31, 2023, $157.4 million and $260.4 million, respectively, are available to be drawn and the remaining amounts under the financing arrangements which have been secured will be available as construction milestones are completed.

As of December 31, 2024, the Company’s liquidity was sufficient to meet near-term requirements. As of December 31, 2024 the Company had consolidated liquidity of $1,457.4 million, excluding $1,496.5 million of committed but undrawn financings related to our newbuild vessels, which represents an increase from $558.9 million in the prior 2023 period, driven primarily by an increase in cash of $528.5 million and an increase in the undrawn amounts under the revolving credit facilities. In addition, with 35 vessel deliveries in 2024 and an additional one expected in 2025, all of which are on long-term charters, such deliveries will generate incremental cashflow.

Unencumbered Assets

The Company’s growing base of unencumbered assets is a fundamental objective to achieving an investment grade credit rating, as well as a potential source of liquidity through secured financing or asset sales. Over the long-term, the Company expects its unencumbered asset base to grow as it enhances its presence in the unsecured credit markets, and also naturally as secured borrowings mature or are prepaid.

In the short-term, the Company expects that its unencumbered asset base may fluctuate as unencumbered assets may be sold or financed from time to time, as part of normal course management of assets and liquidity.

The following table provides a summary of our unencumbered fleet and net book value over time.

	As at December 31,
(in millions of USD)	2020		2021		2022		2023		2024

Net Book Value	$	1,109	$	1,369	$	1,847	$	1,923	$	2,115

Contracted Cash Flows

The Company’s focus on long-term contracted cash flows provides predictability and reduces liquidity risk through economic cycles. As of December 31, 2024, the Company had total gross contracted cash flows of $26.1 billion, which includes components that are accounted for differently, including i) minimum future revenues relating to operating leases with customers, ii) minimum cash flows to be received relating to financing leases with certain customers, and iii) contracted cash flows underlying leases for newbuild vessels which have not yet been delivered to customers.

(in millions of U.S. dollars)	Operating lease revenue (1)		Lease receivable on financing leases		Gross contracted cash flows for newbuilds
2025	$	2,094.5	$	238.0	$	32.1
2026	1,965.4		238.0		14.7
2027	1,815.4		238.0		156.4
2028	1,436.6		238.7		433.9
2029	1,277.1		238.0		686.0
Thereafter	5,061.4		3,032.6		6,929.2
	$	13,650.4	$	4,223.3	$	8,252.3

(1)Minimum future operating lease revenue includes payments from signed charter agreements on operating vessels that have not yet commenced

Minimum future revenues assume that, during the term of the lease, (i) there will be no unpaid days, (ii) extensions are included where exercise is at our unilateral option, and (iii) extensions are excluded where exercise is at the charterers’ option. Minimum future revenues do not reflect signed charter agreements for undelivered vessels.

The Company is focused on continuing to allocate capital selectively into opportunities that enhance the long-term value of the business and provide attractive risk-adjusted returns on capital, including evaluating synergistic opportunities in adjacent businesses to diversify cash flow drivers.

The Company intends to continue its growth trajectory in 2025, further growing its liquidity through capital recycling and expansion of its revolving credit facilities, diversifying sources of capital to enhance financial flexibility, managing leverage in alignment with its long-term targets, and growing the value of its unencumbered asset base.

The Company’s primary liquidity needs include funding our investments in assets including our newbuild vessels under construction, scheduled debt and lease payments, vessel purchase commitments, potential future exercises of vessel purchase options, and dividends on our common shares.

Operating borrowings(3)	$	10,377.5	$	6,679.3	$	3,698.2	55.4	%

(1)Corresponds to the following: (i) 2024 NOK Bonds and 2026 NOK Bonds which were repaid in February 2024 and (ii) 5.5% senior unsecured notes due in 2029.

(2)Corresponds to Sustainability-Linked Senior Secured Notes with fixed interest rates ranging from 3.91% to 5.49% and maturities between 2031 and 2037.

(3)Total borrowings is a non-GAAP financial measure which consists of long-term debt, other financing arrangements and finance leases, excluding deferred financing fees. The Company’s total borrowings include amounts related to vessels under construction, consisting primarily of amounts borrowed to pay installments to shipyards. The interest incurred on borrowings related to the vessels under construction are capitalized during the construction period. Operating borrowings is a non-GAAP financial measure which is total borrowings less the vessels under construction balance at the balance sheet date. Total borrowings and operating borrowings are non-GAAP financial measures that are not defined under or prepared in accordance with U.S. GAAP. Disclosure of total borrowings and operating borrowings is intended to provide additional information and should not be considered a substitute for financial measures prepared in accordance with U.S. GAAP. Management believes these measures are useful in consolidating and clearly presenting Company’s financings. Management also believes that these metrics can be useful to facilitate assessment of leverage and debt service obligations of the Company. Management believes operating borrowings is a useful measure to assess interest expense related to vessels that are in operation and generating revenue.

The Company’s approach is to target a total borrowings-to-asset ratio of 50-60%, and to mitigate credit risk by diversifying its maturity profile over as long a term as economically feasible, while maintaining or reducing its cost of capital. The Company’s total borrowings-to-asset ratio was 66.7% as of December 31, 2024, compared to 61.2% at December 31, 2023, partially due to the borrowings related to vessels under construction.

The weighted average interest rate for December 31, 2024 was 6.14% compared to 6.85% at December 31, 2023.

We are exposed to market rate risk from changes in interest rates and use interest rate swaps to manage interest price risks. We do not use interest rate swaps for trading or speculative purposes. As of December 31, 2024, our variable-rate credit facilities totaled $1.1 billion, of which we had entered into interest rate swap agreements to fix the rates on a notional principal amount of $1.1 billion. As of December 31, 2024, we have an asset of $97.4 million related to our interest rate swaps.

These leases are provided by bank financial leasing owners who legally own our vessels through special purpose entities and are also granted other related security, such as assignments of time charters, earnings for the vessels, insurances for the vessels and management agreements for the vessels. We use these arrangements to finance the construction and acquisition of vessels, as well as certain of our operating vessels.

As of December 31, 2024, we have 92 vessels under these financing arrangements, which provided for borrowings of approximately $7.8 billion excluding deferred financing fees.

Summary of Consolidated Statements of Cash Flows

The following table summarizes our sources and uses of cash for the periods presented:

(in millions of US dollars)	December 31,
	2024		2023
Net cash flows from operating activities	$	1,519.5	$	993.7
Net cash flows used in investing activities	(3,322.8)		(2,949.0)
Net cash flows from financing activities	2,331.8		2,033.5

Operating Cash Flows

Net cash flows from operating activities was $1,519.5 million for the year ended December 31, 2024, an increase of $525.8 million, compared to 2023. The increase in net cash flows from operating activities for the year ended December 31, 2024, compared to the prior year, was primarily due to net cash flows from the full year impact of 22 vessels delivered in 2023 and the delivery of 35 newbuild vessels in the year, offset by the impact of two vessel sales in the year. For further discussion of changes in revenue and expenses, please read “Financial Results Summary”.

Investing Cash Flows

Net cash flows used in investing activities were $3,322.8 million for the year ended December 31, 2024, an increase of $373.8 million compared to 2023. The increase in cash used was primarily due to the increase in expenditures related to installments on vessels under construction, and a decrease in proceeds from vessel sales in the year ended December 31, 2023.

Financing Cash Flows

Net cash flows from financing activities were $2,331.8 million for the year ended December 31, 2024, an increase of $298.3 million compared to 2023. The increase was primarily due to proceeds received from long-term debt and other financing arrangements related to newbuild financing partially offset by the debt settlement costs associated with the Take-Private.

Ongoing Capital Expenditures

Ongoing Capital Expenditures

The average age of the vessels in our containership fleet is approximately seven years, on a TEU-weighted basis. Capital expenditures for our containership fleet primarily relate to our regularly scheduled dry-dockings. During the year ended December 31, 2024, we completed 11 dry-dockings, compared to 44 dry-dockings in 2023.

We must make substantial capital expenditures over the long-term to preserve our capital base, which is comprised of our net assets, to continue to refinance our indebtedness and to maintain our dividends. We will likely need to retain additional funds at some time in the future to provide reasonable assurance of maintaining our capital base over the long-term. We believe it is not possible to determine now, with any reasonable degree of certainty, how much of our operating cash flow we should retain in our business and when it should be retained to preserve our capital base. The amount of operating cash flow we retain in our business will affect the amount of our dividends. Factors that will impact our decisions regarding the amount of funds to be retained in our business to preserve our capital base, include the following, many of which are currently unknown and are outside our control:

(1)the remaining lives of our vessels;

(2)the returns that we generate on our retained cash flow, which will depend on the economic terms of any future asset acquisitions and lease terms;

(3)future contract rates for our assets after the end of their existing leases agreements;

(4)future operating and financing costs; 

48

(5)our future refinancing requirements and alternatives and conditions in the relevant financing and capital markets at that time; and

(6)unanticipated future events and other contingencies.

Please read “Item 3. Key Information – D. Risk Factors” in Atlas’ 2024 Annual Report for factors that may affect our future capital expenditures and results.

Critical Accounting Policies and Estimates

We prepare our consolidated financial statements in accordance with U.S. GAAP, which requires us to make estimates in the application of our accounting policies based on our best assumptions, judgments and opinions. Our estimates affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosures. We base our estimates on historical experience and anticipated results and trends and on various other assumptions that we believe are reasonable under the circumstances. However, because future events and their effects cannot be determined with certainty, actual results could differ from our assumptions and estimates, and such differences could be material. For more information about our critical accounting estimates, please read “Item 5. Operating and Financial Review and Prospects - E. Critical Accounting Estimates” in Atlas’ 2024 Annual Report.

ITEM 3 — QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to market risk from changes in interest rates and foreign currency fluctuations. We use interest rate swaps to manage interest rate price risks. We do not use interest rate swaps for trading or speculative purposes.

Interest Rate Risk

As of December 31, 2024, our variable-rate credit facilities totaled $1.1 billion, of which we had entered into sixinterest rate swap agreements to fix the rates on a notional principal amount of $1.1billion. These interest rate swaps mature between 2025 and 2032 and have a fair value of $98.7million in our favor, on a net basis. Counterparties to these financial instruments may expose us to credit-related losses in the event of non-performance. As of December 31, 2024, these financial instruments are in our favor. We have considered and reflected the risk of non-performance by us in the fair value of our financial instruments as of December 31, 2024. As part of our consideration of non-performance risk, we perform evaluations of our counterparties for credit risk through ongoing monitoring of their financial health and risk profiles to identify funding risk or changes in their credit ratings.

The tables below provide information about our financial instruments at December 31, 2024 that are sensitive to changes in interest rates. In addition to the disclosures in this report, please read note 8 to 11 to our consolidated financial statements included in this Report, which provide additional information with respect to our existing credit and lease facilities.

	Principal Payment Dates
(in millions of US dollars)	2025		2026		2027		2028		2029		Thereafter
Credit Facilities(1)	$	103.9	$	103.9	$	103.9	$	444.0	$	311.6	$	4.4
Vessel Operating Leases(2)	13.8		14.1		15.4		14.4		5.8		—
Vessel Finance Leases(3)	409.4		—		—		—		—		—
Sale-Leaseback Facilities(4)	493.5		490.8		504.6		513.2		551.6		5,198.1

(1) Represents principal payments on amounts drawn on our credit facilities that bear interest at variable rates. We have entered into interest rate swap agreements under certain of our credit facilities to swap the variable interest rates for fixed interest rates. For the purposes of this table, principal payments are determined based on contractual repayments in commitment reduction schedules for each related facility.

(2) Represents payments under our operating leases. Payments under the operating leases have a variable component based on underlying interest rates.

(3) Represents payments under our finance leases. Payments under the finance leases have a variable component based on underlying interest rates.

(4) Represents payments, excluding amounts representing interest payments, on amounts drawn on our sale-leaseback facilities where the vessels remain on our balance sheet and that bear interest at variable rates.

As of December 31, 2024, we had the following interest rate swaps outstanding:

Fixed per annum rate swapped for benchmark rate	Notional amount as of December 31, 2024		Maximum notional amount(1)		Effective date	Ending date
1.7574%	$	500.0	$	500.0	January 31, 2022	February 2, 2032

1.4900%	19.2		19.2		February 4, 2020	December 30, 2025
	$	1,105.2	$	1,105.2

(1) Over the term of the interest rate swaps, the notional amounts increase and decrease. These amounts represent the peak notional amount over the remaining term of the swap.

(2) $250,000,000 notional amount transaction on daily SOFR with a cap of 5.5% and a floor strike of 2.67%

Counterparties to these financial instruments may expose us to credit-related losses in the event of non-performance. As of December 31, 2024, these financial instruments are both in the counterparties’ favor and our favor. We have considered and reflected the risk of non-performance by us in the fair value of our financial

52

instruments as of December 31, 2024. As part of our consideration of non-performance risk, we perform evaluations of our counterparties for credit risk through ongoing monitoring of their financial health and risk profiles to identify funding risk or changes in their credit ratings.

Counterparties to these agreements are major financial institutions, and we consider the risk of loss due to non-performance to be minimal. We do not require collateral from or pay collateral to these institutions. We do not hold and will not issue interest rate swaps for trading purposes.
