Basis of preparation	2 Basis of Preparation Statement of compliance These consolidated financial statements were prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB) and accounting requirements of OSFI in accordance with Section 308 of the Bank Act. Section 308 states that, except as otherwise specified by OSFI, the financial statements are to be prepared in accordance with IFRS. The consolidated financial statements for the year ended October 31, 2022 have been approved by the Board of Directors for issue on November 29, 2022. Certain comparative amounts have been restated to conform with the basis of presentation in the current year. Basis of measurement The consolidated financial statements have been prepared on the historical cost basis except for the following material items that are measured at fair value in the Consolidated Statement of Financial Position: • Financial assets and liabilities measured at fair value through profit or loss • Financial assets and liabilities designated at fair value through profit or loss • Derivative financial instruments • Equity instruments designated at fair value through other comprehensive income • Debt instruments measured at fair value through other comprehensive income Functional and presentation currency These consolidated financial statements are presented in Canadian dollars, which is the Bank’s functional currency. All financial information presented in Canadian dollars has been rounded to the nearest million unless otherwise stated. Management’s use of estimates, assumptions and judgments The Bank’s accounting policies require estimates, assumptions and judgments that relate to matters that are inherently uncertain. The Bank has established procedures to ensure that accounting policies are applied consistently. Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the year in which the estimates are revised. Use of estimates and assumptions The preparation of these consolidated financial statements, in conformity with IFRS, requires management to make estimates and assumptions that affect the reported amount of assets and liabilities at the date of the consolidated financial statements, and other comprehensive income and income and expenses during the reporting period. Estimates made by management are based on historical experience and other factors and assumptions that are believed to be reasonable. Key areas of estimation uncertainty include those relating to the allowance for credit losses, the fair value of financial instruments (including derivatives), corporate income taxes, employee benefits, goodwill and intangible assets, the fair value of all identifiable assets and liabilities as a result of business combinations, impairment of non-financial Significant judgments In the preparation of these consolidated financial statements, management is required to make significant judgments in the classification and presentation of transactions and instruments and accounting for the Bank’s involvement with other entities. Significant estimates, assumptions and judgments have been made in the following areas and are discussed as noted in the consolidated financial statements: Allowance for credit losses Note 3 Note 13(d) Fair value of financial instruments Note 3 Note 7 Corporate income taxes Note 3 Note 27 Employee benefits Note 3 Note 28 Goodwill and intangible assets Note 3 Note 18 Fair value of all identifiable assets and liabilities as a result of business combinations Note 3 Note 36 Impairment of investment securities Note 3 Note 12 Impairment of non-financial Note 3 Note 16 Structured entities Note 3 Note 15 De facto control of other entities Note 3 Note 31 Derecognition of financial assets and liabilities Note 3 Note 14 Provisions Note 3 Note 23

Significant accounting policies	3 Significant Accounting Policies The significant accounting policies used in the preparation of these consolidated financial statements, including any additional accounting requirements of OSFI, as set out below, have been applied consistently to all periods presented in these consolidated financial statements. Basis of consolidation The consolidated financial statements include the assets, liabilities, financial performance and cash flows of the Bank and all of its subsidiaries, after elimination of intercompany transactions and balances. Subsidiaries are defined as entities controlled by the Bank. The Bank’s subsidiaries can be classified as entities controlled through voting interests or structured entities. The Bank consolidates a subsidiary from the date it obtains control. For the Bank to control an entity, all three elements of control should be in existence: • power over the investee; • exposure, or rights, to variable returns from involvement with the investee; and • the ability to use power over the investee to affect the amount of the Bank’s returns. The Bank does not control an investee when it is acting as an agent. The Bank assesses whether it is an agent by determining whether it is primarily engaged to act on behalf of and for the benefit of another party or parties. The Bank reassesses whether it controls an investee if facts and circumstances indicate that one or more of the elements of control has changed. Voting-interest subsidiaries Control is presumed with an ownership interest of more than 50% of the voting rights in an entity unless there are other factors that indicate that the Bank does not control the entity despite having more than 50% of voting rights. The Bank may consolidate an entity when it owns less than 50% of the voting rights when it has one or more other attributes of power: • by virtue of an agreement, over more than half of the voting rights; • to govern the financial and operating policies of the entity under a statute or an agreement; • to appoint or remove the majority of the members of the board of directors or equivalent governing body and control of the entity is by that board or body; or • to govern the financial and operating policies of the entity through the size of its holding of voting rights relative to the size and dispersion of holding of the other vote holders and voting patterns at shareholder meetings (i.e., de facto control). Non-controlling non-controlling non-controlling Structured entities Structured entities are designed to accomplish certain well-defined objectives and for which voting or similar rights are not the dominant factor in deciding who controls the entity. The Bank controls an entity when it is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. The Bank consolidates all structured entities that it controls. Investments in associates An associate is an entity in which the Bank has significant influence, but not control, over the operating and financial policies of the entity. Investments in associates are recognized initially at cost, which includes the purchase price and other costs directly attributable to the purchase. Associates are accounted for using the equity method which reflects the Bank’s share of the increase or decrease of the post-acquisition earnings and other movements in the associate’s equity. Investments in associates are evaluated for impairment at the end of each financial reporting period, or more frequently if events or changes in circumstances indicate the existence of objective evidence of impairment. For purposes of applying the equity method for an investment that has a different reporting period from the Bank, adjustments are made for the effects of any significant events or transactions that occur between the reporting date of the investment and the reporting date of the Bank. Joint arrangements The Bank’s investments in joint arrangements over which the Bank has joint control are classified as either joint operations or joint ventures depending on the contractual rights and obligations of each investor, rather than the legal structure of the joint arrangement. Similar to accounting for investment in associates, for joint ventures, investments are recognized initially at cost and accounted for using the equity method which reflects the Bank’s share of the increase or decrease of the post-acquisition earnings and other movements in the joint venture’s equity. Investments in joint ventures are evaluated for impairment at the end of each financial reporting period, or more frequently if events or changes in circumstances indicate the existence of objective evidence of impairment. For joint operations, the Bank recognizes its direct rights to, and its share of jointly held assets, liabilities, revenues and expenses. These have been incorporated in the consolidated financial statements under the appropriate headings. Translation of foreign currencies The financial statements of each of the Bank’s foreign operations are measured using its functional currency, being the currency of the primary economic environment of the foreign operation. Translation gains and losses related to the Bank’s monetary items are recognized in non-interest non-monetary non-monetary non-monetary non-monetary Unrealized gains and losses arising upon translation of foreign operations, together with any gains or losses arising from hedges of those net investment positions to the extent effective, are credited or charged to net change in unrealized foreign currency translation gains/losses in other comprehensive income in the Consolidated Statement of Comprehensive Income. On disposal or meeting the definition of partial disposal of a foreign operation, an appropriate portion of the translation differences previously recognized in other comprehensive income are recognized in the Consolidated Statement of Income. Financial assets and liabilities Recognition and initial measurement The Bank, on the date of origination or purchase, recognizes loans, debt and equity securities, deposits and subordinated debentures at the fair value of the consideration paid or received. Regular-way The initial measurement of a financial asset or liability is at fair value plus transaction costs that are directly attributable to its purchase or issuance. For instruments measured at fair value through profit or loss, transaction costs are recognized immediately in profit or loss. Classification and measurement, derecognition, and impairment of financial instruments Classification and measurement Classification and measurement of financial assets Financial assets include both debt and equity instruments, are classified into one of the following measurement categories: • Amortized cost; • Fair value through other comprehensive income (FVOCI); • Fair value through profit or loss (FVTPL); • Elected at fair value through other comprehensive income (Equities only); or • Designated at FVTPL Debt instruments Debt instruments, including loans and debt securities, are classified into one of the following measurement categories: • Amortized cost; • Fair value through other comprehensive income (FVOCI); • Fair value through profit or loss (FVTPL); or • Designated at FVTPL Classification of debt instruments is determined based on: (i) The business model under which the asset is held; and (ii) The contractual cash flow characteristics of the instrument. Business model assessment A business model assessment involves determining how financial assets are managed to generate cash flows. The Bank’s business model assessment is based on the following categories: • Held to collect: The objective of this business model is to hold assets and collect contractual cash flows. Any sales of the asset are incidental to the objective of the model. • Held to collect and for sale: Both collecting contractual cash flows and sales are integral to achieving the objectives of the business model. • Other business model: The business model is neither held-to-collect held-to-collect The Bank assesses the business model at a portfolio level reflective of how groups of assets are managed together to achieve a particular business objective. For the assessment of a business model, the Bank takes into consideration the following factors: • How the performance of assets in a portfolio is evaluated and reported to group heads and other key decision makers within the Bank’s business lines; • How compensation is determined for the Bank’s business lines’ management that manages the assets; • How the business lines’ management is compensated for managing the Bank’s assets based on the fair value or the contractual cash flows collected; • Whether the assets are held for trading purposes; • The risks that affect the performance of assets held within a business model and how those risks are managed; and • The frequency and volume of sales in prior periods and expectations about future sales activity. Contractual cash flow characteristics assessment The contractual cash flow characteristics assessment involves assessing the contractual features of an instrument to determine if they give rise to cash flows that are consistent with a basic lending arrangement. Contractual cash flows are consistent with a basic lending arrangement if they represent cash flows that are solely payments of principal and interest on the principal amount outstanding (SPPI). Principal is defined as the fair value of the instrument at initial recognition. Principal may change over the life of the instrument due to repayments or amortization of premium/discount. Interest is defined as the consideration for the time value of money and the credit risk associated with the principal amount outstanding and for other basic lending risks and costs (liquidity risk and administrative costs), and a profit margin. If the Bank identifies any contractual features that could significantly modify the cash flows of the instrument such that they are no longer consistent with a basic lending arrangement, the related financial asset is classified and measured at FVTPL. Debt instruments measured at amortized cost Debt instruments are measured at amortized cost if they are held within a business model whose objective is to hold for collection of contractual cash flows where those cash flows represent solely payments of principal and interest. After initial measurement, debt instruments in this category are carried at amortized cost. Interest income on these instruments is recognized in interest income using the effective interest rate method. The effective interest rate is the rate that discounts estimated future cash payments or receipts through the expected life of the financial asset to the gross carrying amount of a financial asset. Amortized cost is calculated by taking into account any discount or premium on the acquisition, transaction costs and fees that are an integral part of the effective interest rate. Impairment on debt instruments measured at amortized cost is calculated using the expected credit loss approach. Loans and debt securities measured at amortized cost are presented net of the allowance for credit losses (ACL) in the Statement of Financial Position. Debt instruments measured at FVOCI Debt instruments are measured at FVOCI if they are held within a business model whose objective is to hold for collection of contractual cash flows and for selling financial assets, where the assets’ cash flows represent payments that are solely payments of principal and interest. Subsequent to initial recognition, unrealized gains and losses on debt instruments measured at FVOCI are recorded in other comprehensive income (OCI), unless the instrument is designated in a fair value hedge relationship. When designated in a fair value hedge relationship, any changes in fair value due to changes in the hedged risk are recognized in Non-interest Non-interest Impairment on debt instruments measured at FVOCI is determined using the expected credit loss approach. The ACL on debt instruments measured at FVOCI does not reduce the carrying amount of the asset in the Consolidated Statement of Financial Position, which remains at its fair value. Instead, an amount equal to the allowance that would arise if the assets were measured at amortized cost is recognized in OCI with a corresponding charge to provision for credit losses in the Consolidated Statement of Income. The accumulated allowance recognized in OCI is recycled to the Consolidated Statement of Income upon derecognition of the debt instrument. Debt instruments measured at FVTPL Debt instruments are measured at FVTPL if assets: (i) are held for trading purposes; (ii) are held as part of a portfolio managed on a fair value basis; or (iii) whose cash flows do not represent payments that are solely payments of principal and interest. These instruments are measured at fair value in the Consolidated Statement of Financial Position, with transaction costs recognized immediately in the Consolidated Statement of Income as part of Non-interest Non-interest Debt instruments designated at FVTPL The Bank designates certain debt instruments at FVTPL upon initial recognition, and the designation is irrevocable. The FVTPL designation is available when a fair value is reliably estimated, and doing so eliminates or significantly reduces an accounting mismatch which would otherwise arise. Debt instruments designated at FVTPL are recorded in the Consolidated Statement of Financial Position at fair value. Changes in fair value are recognized in Non-interest Equity instruments Equity instruments are classified into one of the following measurement categories: • Fair value through profit or loss (FVTPL); or • Elected at fair value through other comprehensive income (FVOCI). Equity instruments measured at FVTPL Equity instruments are measured at FVTPL, unless an election is made to designate them at FVOCI upon purchase, with transaction costs recognized immediately in the Consolidated Statement of Income as part of Non-interest Equity instruments measured at FVOCI At initial recognition, the Bank has an option to classify non-trading instrument-by-instrument Gains and losses on these instruments, including when derecognized/sold, are recorded in OCI and are not subsequently reclassified to the Consolidated Statement of Income. As such, there is no specific impairment requirement. Dividends received are recorded in Interest income in the Consolidated Statement of Income. Any transaction costs incurred upon purchase of the security are added to the cost basis of the security and are not reclassified to the Consolidated Statement of Income on sale of the security. Classification and measurement of financial liabilities Financial liabilities are classified into one of the following measurement categories: • Fair value through profit or loss (FVTPL); • Amortized cost; or • Designated at FVTPL. Financial liabilities measured at FVTPL Financial liabilities measured at FVTPL are held principally for the purpose of repurchasing in the near term, or form part of a portfolio of identified financial instruments that are managed together and for which there is evidence of a recent actual pattern of short term profit-taking. Financial liabilities are recognized on a trade date basis and accounted for at fair value, with changes in fair value and any gains or losses recognized in the Consolidated Statement of Income as part of the non-interest Financial liabilities measured at amortized cost Deposits, subordinated notes and debentures are accounted for at amortized cost. Interest on deposits, calculated using the effective interest rate method, is recognized as interest expense. Interest on subordinated notes and debentures, including capitalized transaction costs, is recognized using the effective interest rate method as interest expense. Financial liabilities designated at FVTPL The Bank designates certain financial liabilities at FVTPL upon initial recognition, and the designation is irrevocable. The FVTPL designation is available when a fair value is reliably estimated. Financial liabilities are designated at FVTPL when it meets one of the following criteria: • The designation eliminates or significantly reduces an accounting mismatch which would otherwise arise; or • A group of financial liabilities are managed and their performance is evaluated on a fair value basis, in line with a documented risk management strategy; or • The financial liability contains one or more embedded derivatives which significantly modify the cash flows otherwise required. Financial liabilities designated at FVTPL are recorded in the Consolidated Statement of Financial Position at fair value. Any changes in fair value are recognized in Non-interest Determination of fair value The fair value of a financial asset or liability is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the principal, or in its absence, the most advantageous market to which the Bank has access at the measurement date. The Bank values instruments carried at fair value using quoted market prices, where available. Fair value based on unadjusted quoted market prices for identical instruments in active markets represents a Level 1 valuation. When quoted market prices are not available, the Bank maximizes the use of observable inputs within valuation models. When a fair value is based on all significant market observable inputs, the valuation is classified as Level 2. Valuations that require the significant use of unobservable inputs are considered Level 3. Inception gains and losses are only recognized where the valuation is dependent on observable market data; otherwise, they are deferred and amortized over the life of the related contract or until the valuation inputs become observable. IFRS 13, Fair Value Measurement In determining fair value for certain instruments or portfolios of instruments, valuation adjustments or reserves may be required to arrive at a more accurate representation of fair value. These adjustments include those made for credit risk, bid-offer Derecognition of financial assets and liabilities Derecognition of financial assets A financial asset is derecognized when the contractual rights to the cash flows from the asset has expired; or the Bank transfers the contractual rights to receive the cash flows from the financial asset; or has assumed an obligation to pay those cash flows to an independent third-party; or the Bank has transferred substantially all the risks and rewards of ownership of that asset to an independent third-party. Management determines whether substantially all the risk and rewards of ownership have been transferred by quantitatively comparing the variability in cash flows before and after the transfer. If the variability in cash flows remains significantly similar subsequent to the transfer, the Bank has retained substantially all of the risks and rewards of ownership. Where substantially all the risks and rewards of ownership of the financial asset are neither retained nor transferred, the Bank derecognizes the transferred asset only if it has lost control over that asset. Control over the asset is represented by the practical ability to sell the transferred asset. If the Bank retains control over the asset, it will continue to recognize the asset to the extent of its continuing involvement. At times such continuing involvement may be in the form of investment in senior or subordinated tranches of notes issued by non-consolidated On derecognition of a financial asset, the difference between the carrying amount and the sum of (i) the consideration received (including any new asset obtained less any new liability assumed) and (ii) any cumulative gain or loss that had been recognized in other comprehensive income is recognized in the Consolidated Statement of Income. Transfers of financial assets that do not qualify for derecognition are reported as secured financings in the Consolidated Statement of Financial Position. The derecognition criteria are applied to the transfer of part of an asset, rather than the asset as a whole, only if such part comprises specifically identified cash flows from the asset, a fully proportionate share of the cash flows from the asset, or a fully proportionate share of specifically identified cash flows from the asset. Derecognition of financial liabilities A financial liability is derecognized when the obligation under the liability is discharged, canceled or expires. If an existing financial liability is replaced by another from the same counterparty on substantially different terms, or the terms of the existing liability are substantially modified, such an exchange or modification is treated as a derecognition of the original liability and the recognition of a new liability at fair value. The difference in the respective carrying amount of the existing liability and the new liability is recognized as a gain/loss in the Consolidated Statement of Income. Impairment Scope The Bank applies a three-stage approach to measure allowance for credit losses, using an expected credit loss approach as required under IFRS 9, for the following categories of financial instruments that are not measured at fair value through profit or loss: • Amortized cost financial assets; • Debt securities classified as at FVOCI; • Off-balance • Financial guarantee contracts. Expected credit loss impairment model The Bank’s allowance for credit losses calculations are outputs of models with a number of underlying assumptions regarding the choice of variable inputs and their interdependencies. The expected credit loss impairment model reflects the present value of all cash shortfalls related to default events either (i) over the following twelve months or (ii) over the expected life of a financial instrument depending on credit deterioration from inception. The allowance for credit losses reflects an unbiased, probability-weighted outcome which considers multiple scenarios based on reasonable and supportable forecasts. This impairment model measures credit loss allowances using a three-stage approach based on the extent of credit deterioration since origination: • Stage 1 – Where there has not been a significant increase in credit risk (SIR) since initial recognition of a financial instrument, an amount equal to 12 months expected credit loss is recorded. The expected credit loss is computed using a probability of default occurring over the next 12 months. For those instruments with a remaining maturity of less than 12 months, a probability of default corresponding to remaining term to maturity is used. • Stage 2 – When a financial instrument experiences a SIR subsequent to origination but is not considered to be in default, it is included in Stage 2. This requires the computation of expected credit loss based on the probability of default over the remaining estimated life of the financial instrument. • Stage 3 – Financial instruments that are considered to be in default are included in this stage. Similar to Stage 2, the allowance for credit losses captures the lifetime expected credit losses. Measurement of expected credit loss The probability of default (PD), exposure at default (EAD), and loss given default (LGD) inputs used to estimate expected credit losses are modelled based on macroeconomic variables that are most closely related with credit losses in the relevant portfolio. Details of these statistical parameters/inputs are as follows: • PD – The probability of default is an estimate of the likelihood of default over a given time horizon. A default may only happen at a certain time over the remaining estimated life if the facility has not been previously derecognized and is still in the portfolio. • EAD – The exposure at default is an estimate of the exposure at a future default date, considering expected changes in the exposure after the reporting date, including repayments of principal and interest, whether scheduled by contract or otherwise, expected drawdowns on committed facilities, and accrued interest from missed payments. • LGD – The loss given default is an estimate of the loss arising in the case where a default occurs at a given time. It is based on the difference between the contractual cash flows due and those that the lender would expect to receive, including from the realization of any collateral. It is usually expressed as a percentage of the EAD. Forward-looking information The estimation of expected credit losses for each stage and the assessment of significant increases in credit risk consider information about past events and current conditions as well as reasonable and supportable forecasts of future events and economic conditions. The estimation and application of forward-looking information may require significant judgment. Macroeconomic factors In its models, the Bank relies on a broad range of forward-looking economic information as inputs, such as: GDP growth, unemployment rates, central bank interest rates, and house-price indices. The inputs and models used for calculating expected credit losses may not always capture all characteristics of the market at the date of the financial statements. Qualitative adjustments or overlays may be made as temporary adjustments using expert credit judgment. Multiple forward-looking scenarios The Bank determines its allowance for credit losses using four probability-weighted forward-looking scenarios. The Bank considers both internal and external sources of information and data in order to achieve unbiased projections and forecasts. The Bank prepares the scenarios using forecasts generated by Scotiabank Economics (SE). The forecasts are created using internal and external models which are modified by SE as necessary to formulate a ‘base case’ view of the most probable future direction of relevant economic variables as well as a representative range of other possible forecast scenarios. The process involves the development of three additional economic scenarios and consideration of the relative probabilities of each outcome. The ‘base case’ represents the most likely outcome and is aligned with information used by the Bank for other purposes such as strategic planning and budgeting. The other scenarios represent more optimistic and more pessimistic outcomes. The Bank has identified and documented key drivers of credit risk and credit losses for each portfolio of financial instruments and, using an analysis of historical data, has estimated relationships between macroeconomic variables, credit risk, and credit losses. Assessment of significant increase in credit risk (SIR) At each reporting date, the Bank assesses whether there has been a significant increase in credit risk for exposures since initial recognition by comparing the risk of default occurring over the remaining expected life from the reporting date and the date of initial recognition. The assessment considers borrower-specific quantitative and qualitative information without consideration of collateral, and the impact of forward-looking macroeconomic factors. The common assessments for SIR on retail and non-retail Retail portfolio – For retail exposures, a significant increase in credit risk cannot be assessed using forward looking information at an individual account level. Therefore, the assessment must be done at the segment level. Segment migration thresholds exist for each PD model by product which considers the proportionate change in PD as well as the absolute change in PD. The thresholds used for PD migration are reviewed and assessed at least annually unless there is a significant change in credit risk management practices in which case the review is brought forward. Non-retail non-retail non-retail non-borrower Expected life When measuring expected credit loss, the Bank considers the maximum contractual period over which the Bank is exposed to credit risk. All contractual terms are considered when determining the expected life, including prepayment, and extension and rollover options. For certain revolving credit facilities, such as credit cards, the expected life is estimated based on the period over which the Bank is exposed to credit risk and how the credit losses are mitigated by management actions. Presentation of allowance for credit losses in the Statement of Financial Position • Financial assets measured at amortized cost: as a deduction from the gross carrying amount of the financial assets; • Debt instruments measured at fair value through other comprehensive income: no allowance is recognized in the Statement of Financial Position because the carrying value of these assets is their fair value. However, the allowance determined is presented in the accumulated other comprehensive income; • Off-balance Modified financial assets If the terms of a financial asset are modified or an existing financial asset is replaced with a new one, an assessment is made to determine if the existing financial asset should be derecognized. Where a modification does not result in derecognition, the date of origination continues to be used to determine SIR. Where a modification results in derecognition, the new financial asset is recognized at its fair value on the modification date. The modification date is also the date of origination for this new asset. The Bank may modify the contractual terms of loans for either commercial or credit reasons. The terms of a loan in good standing may be modified for commercial reasons to provide competitive pricing to borrowers. Loans are also modified for credit reasons where the contractual terms are modified to grant a concession to a borrower that may be experiencing financial difficulty. For all financial assets modifications of the contractual terms may result in derecognition of the original asset when the changes to the terms of the loans are considered substantial. These terms include interest rate, authorized amount, term, or type of underlying collateral. The original loan is derecognized, and the new loan is recognized at its fair value. The difference between the carrying value of the derecognized asset and the fair value of the new asset is recognized in the Consolidated Statement of Income. For all loans, performing and credit-impaired, where the modification of terms did not result in the derecognition of the loan, the gross carrying amount of the modified loan is recalculated based on the present value of the modified cash flows discounted at the original effective interest rate and any gain or loss from the modification is recorded in the provision for credit losses line in the Consolidated Statement of Income. Definition of default The Bank considers a financial instrument to be in default as a result of one or more loss events that occurred after the date of initial recognition of the instrument and the loss event has a negative impact on the estimated future cash flows of the instrument that can be reliably estimated. This includes events that indicate: • significant financial difficulty of the borrower; • default or delinquency in interest or principal payments; • high probability of the borrower entering a phase of bankruptcy or a financial reorganization; • measurable decrease in the estimated future cash flows from the loan or the underlying assets that back the loan. The Bank considers that default has occurred and classifies the financial asset as impaired when it is more than 90 days past due, except for credit card receivables that are treated as defaulted when 180 days past due, unless reasonable and supportable information demonstrates that a more lagging default criterion is appropriate. Write-off The Bank writes off an impaired financial asset (and the related impairment allowance), either partially or in full, when there is no realistic prospect of recovery. Where financial assets are secured, write-off write-off written-off. Purchased loans All purchased loans are initially measured at fair value on the date of acquisition. As a result, no allowance for credit losses would be recorded in the Consolidated Statement of Financial Position on the date of acquisition. Purchased loans may fit into either of the two categories: Performing loans or Purchased Credit - Purchased performing loans follow the same accounting as originated performing loans and are reflected in Stage 1 on the date of the acquisition. They will be subject to a 12-month PCI loans are reflected in Stage 3 and are alwa

Interest Rate Benchmark Reform	4 Interest Rate Benchmark Reform Overview Major interest rate benchmark reviews have been undertaken globally to either reform or phase out certain interbank offered rates (IBORs), including the Canadian Dollar Offered Rate (CDOR). As alternatives to IBORs, regulators have recommended markets begin adopting alternative risk-free rates (RFRs). Further to previous announcements by various regulators, the publication of GBP, JPY, CHF, and EUR LIBORs ceased after December 31, 2021, while most of the USD LIBOR tenors (i.e., overnight, one-month, six-month 12-month The Federal Reserve Board and other U.S. agencies have encouraged banks to transition away from USD LIBOR and cease entering new contracts after December 31, 2021, to facilitate an orderly transition. Similarly, OSFI stated that Federally Regulated Financial Institutions (FRFIs) should not enter new transactions using USD LIBOR as a reference rate after December 31, 2021. On March 15, 2022, the U.S. Federal LIBOR legislation was signed into law establishing a framework for the replacement of USD LIBOR as the benchmark interest rate in existing contracts lacking effective fallback provisions that are difficult to amend before the cessation. On May 16, 2022, Refinitiv Benchmark Services (UK) Limited (RBSL), the administrator of the CDOR, announced the cessation of the publication of one-month, two-month, one-month, two-month, IBOR reform and the associated move from IBORs to RFRs carries systemic and market risks. These risks, such as increased volatility, lack of liquidity and uneven fallback practices, may impact market participants. In addition to these inherent risks, the Bank is exposed to operational risk arising from the renegotiation of contracts, technology readiness to issue and trade products referencing RFRs, and conduct with clients and counterparties. The Bank has established an enterprise-wide program (the Transition Program) to support the Bank’s transition away from IBORs to RFRs. The focus of the Transition Program is to address risks by identifying the exposures to various IBORs, evaluating the existing contract language in the event the IBORs cease to be published or available, developing the capabilities to issue and trade products referencing RFRs and communicating with clients and counterparties regarding industry developments pertaining to IBOR reform. The Transition Program provides quarterly updates to the Bank’s Regulatory Oversight Committee, and annually, to the Risk Committee of the Board of Directors, regarding the status of transition plans for migrating the Bank’s IBOR-linked products and upgrading systems and processes. The Transition Program continues its efforts on the transition of products referencing USD LIBOR and ensuring the Bank is not building its exposure to USD LIBOR, except as permitted by the regulators. As well, the Transition Program has updated its project plans to align with the CDOR transition roadmap and milestones published by the CARR committee and ensure alignment with OSFI’s expectations for FRFIs.

Future accounting developments	5 Future Accounting Developments The Bank actively monitors developments and changes in accounting standards from the IASB, as well as requirements from the other regulatory bodies, including OSFI. The Bank is currently assessing the impact of adoption of new standards issued by the IASB on its consolidated financial statements and also evaluating the alternative elections available on transition. Effective November 1, 2023 Insurance Contracts The International Accounting Standards Board issued IFRS 17 Insurance Contracts Under IFRS 17, groups of insurance contracts will be measured using current probability-weighted fulfillment cash flows and revenue will be recognized as the service is provided over the coverage period, based on the three measurement models as applicable: the general measurement model, the variable fee approach and the premium allocation approach. For groups of contracts that are measured under the general measurement model and the variable fee approach, the contractual service margin will be recognized at initial recognition as a component of the carrying amount of the insurance contracts. Contractual service margin represents unearned profits to be recognized as coverage is provided in the future. The premium allocation approach will be applied to short duration contracts and results in insurance revenue being recognized over the coverage period systematically. For all measurement models, if the group of contracts is expected to be onerous, the losses will be recognized immediately. IFRS 17 will be effective for the Bank from November 1, 2023 and is being implemented as a multi-year project for the Bank’s insurance and reinsurance entities. The project has an established governance structure led by the Executive Steering and Project Operations Committees assisted by a Project Management Office. The committees are comprised of representatives from Finance, Insurance Actuarial Services, Technology and the Insurance Business Operations. The Project involves technology implementation, policy and process changes to support the IFRS 17 processes. The Bank continues to assess and formulate the impact of adopting the new standard, including quantification.

Fair Value of Financial Instruments	7 Fair Value of Financial Instruments Determination of fair value The calculation of fair value is based on market conditions at a specific point in time and therefore may not be reflective of future fair values. The Bank has controls and processes in place to ensure that the valuation of financial instruments is appropriately determined. The Bank discloses the classification of all financial instruments carried at fair value in a hierarchy based on the determination of fair value. The best evidence of fair value for a financial instrument is the quoted price in an active market. Fair value based on unadjusted quoted market prices for identical instruments in active markets represents a Level 1 valuation. Where possible, valuations are based on quoted prices or observable inputs obtained from active markets. Independent Price Verification (IPV) is undertaken to assess the reliability and accuracy of prices and inputs used in the determination of fair value. The IPV process is performed by price verification groups that are independent of the business. The Bank maintains a list of pricing sources that are used in the IPV process. These sources include, but are not limited to, brokers, exchanges and pricing services. The valuation policies relating to the IPV process require that all pricing or rate sources used be external to the Bank. At least annually, an independent assessment of pricing or rate sources is performed to determine the market presence or market representative levels. Quoted prices are not always available for over-the-counter Where financial instruments trade in inactive markets or when using models where observable parameters do not exist, significant management judgment is required for valuation methodologies and model inputs. Valuations that require the significant use of unobservable inputs are considered Level 3. The specific inputs and valuation techniques used in determining the fair value of financial instruments are noted below. For Level 3 instruments, additional information is disclosed in the Level 3 sensitivity analysis on page 1 71 The fair values of cash and deposits with banks, securities purchased under resale agreements and securities borrowed, customers’ liability under acceptances, obligations related to securities sold under repurchase agreements and securities lent, acceptances, and obligations related to securities sold short are assumed to approximate their carrying values, either due to their short-term nature or because they are frequently repriced to current market rates. Trading loans Trading loans are comprised of loans for market making, loans that serve as hedges to total return swaps, purchased mortgages pooled for securitization, and precious metal loans. Trading loans for market making or that serve as hedges to loan-based credit total return swaps are valued using consensus prices from Bank approved independent pricing services. Purchased mortgages that are held prior to securitization are valued using inputs observed from the MBS market. Precious metal loans are valued using a discounted cash flow model incorporating observable market inputs, including precious metals spot and forward prices and interest rate curves. Government issued or guaranteed securities The fair values of government issued or guaranteed debt securities are primarily based on unadjusted quoted prices in active markets, where available. Where quoted prices in active markets are not available, the fair value is determined by utilizing recent transaction prices, reliable broker quotes, or pricing services, which derive fair values using only observable valuation inputs, which are significant to the fair values. For securities for which quoted prices are not available, the Bank uses a discounted cash flow method, using the effective yield of a similar instrument adjusted for instrument-specific risk factors that are observable inputs such as credit spread and contracted features. Corporate and other debt Corporate and other debt securities are valued using unadjusted quoted prices from independent market data providers or third-party broker quotes from an active market. Where direct prices from active markets are not available, the valuation is performed with a yield-based valuation approach. In some instances, interpolated yields of similar bonds are used to price securities. The Bank uses pricing models with observable inputs from market sources such as credit spread, interest rate curves, and recovery rates. These inputs are verified through an IPV process on a monthly basis. For certain securities where there is no active market, no consensus market pricing and no indicative or executable independent third-party quotes, the Bank uses pricing by third-party providers or internal pricing models and cannot readily observe the significant inputs used to price such instruments. Mortgage-backed securities The fair value of residential mortgage-backed securities is primarily determined using broker quotes and independent market data providers. In limited circumstances, an internal price-based model may be used with the unobservable inputs that are significant to the fair value. Equity securities The fair value of equity securities is based on unadjusted quoted prices in active markets, where available. Where equity securities are less frequently traded, the most recent exchange-quoted pricing is used to determine fair value. For private equity securities, where quoted prices in active markets are not readily available, the fair value is determined as a multiple of the underlying earnings or percentage of underlying net asset value obtained from third-party general partner statements. Derivatives Fair values of exchange-traded derivatives are based on unadjusted quoted market prices from an active market. Fair values of over-the-counter Derivative products valued using a valuation technique with market-observable inputs mainly include interest rate swaps and options, currency swaps and forward foreign exchange contracts. The most frequently applied valuation techniques include forward pricing and swap models, using present value calculations. The models incorporate various inputs including foreign exchange spot, forward rates and interest rate curves. Derivative products valued using a valuation technique with significant unobservable inputs, such as volatility, correlation, and forward curves, may include long dated contracts (interest rate swaps, currency swaps, option contracts, commodity contracts and certain credit default swaps) and other derivative products that reference a basket of assets. Loans The estimated fair value of loans carried at amortized cost reflects changes in the general level of interest rates and creditworthiness of borrowers that have occurred since the loans were originated or purchased. The particular valuation methods used are as follows: • Canadian fixed rate residential mortgages are fair valued by discounting the expected future contractual cash flows, taking into account expected prepayments and using management’s best estimate of average market interest rates currently offered for mortgages with similar remaining terms. • For fixed rate business and government loans, fair value is determined by discounting the expected future contractual cash flows of these loans at interest rates estimated by using the appropriate currency swap curves for the remaining term, adjusted for a credit mark of the expected losses in the portfolio. • For all other fixed rate loans, fair value is determined by discounting the expected future contractual cash flows of these loans at interest rates estimated by using the appropriate currency swap curves for the remaining term. • For all floating rate loans fair value is assumed to equal book value. The fair value of loans is not adjusted for the value of any credit protection the Bank has purchased to mitigate credit risk. Deposits The fair values of deposits payable on demand or after notice or floating rate deposits payable on a fixed date is assumed to equal book value. The estimated fair values of Canadian personal fixed rate deposits payable on a fixed date are fair valued by discounting the expected future contractual cash outflows, using management’s best estimate of average market interest rates currently offered for deposits with similar remaining terms. Deposits under the Canada Mortgage Bond (CMB) program are fair valued by discounting expected future contractual cash flows using market observable inputs. For all other fixed rate deposits, fair value is determined by discounting the expected future contractual cash flows of these deposits at interest rates estimated by using the appropriate currency swap curves for the remaining term. For structured notes containing embedded features that are bifurcated from plain vanilla notes, the fair value of the embedded derivatives is determined using option pricing models with observable inputs similar to other interest rate or equity derivative contracts. Certain deposits that are designated at FVTPL are structured notes. Their coupon or repayment terms can be linked to the performance of market parameters such as interest rates, equities, and foreign currencies. The fair value of these structured notes is determined using models which incorporate observable market inputs, such as interest rate curves, equity prices, equity volatility and foreign exchange rates. Some structured notes may have significant unobservable inputs to model valuation such as interest rate volatility and equity correlation. Obligations related to securities sold short The fair values of these obligations are based on the fair value of the underlying securities, which can include debt or equity securities. The method used to determine fair value is based on the quoted market prices where available in an active market. Subordinated debentures and other liabilities The fair values of subordinated debentures, including debentures issued by subsidiaries which are included in other liabilities, are determined by reference to quoted market prices where available or market prices for debt with similar terms and risks. The fair values of other liabilities are determined by the discounted contractual cash flow method with appropriate currency swap curves for the remaining term or market prices for instruments with similar terms and risks. Fair value of financial instruments The following table sets out the fair values of financial instruments of the Bank using the valuation methods and assumptions described above.

For the Bank’s financial instruments carried at cost or amortized cost, the carrying value is not adjusted to reflect increases or decreases in fair value due to market fluctuations, including those due to interest rate changes. For FVOCI investment securities, derivatives and financial instruments measured at FVTPL or designated as fair value through profit or loss, the carrying value is adjusted regularly to reflect the fair value.

Significant transfers Significant transfers can occur between the fair value hierarchy levels when additional or new information regarding valuation inputs and their refinement and observability becomes available. The Bank recognizes transfers between levels of the fair value hierarchy at the end of the reporting period during which the change has occurred. The following significant transfers made between Levels 1 and 2 were based on whether the fair value was determined using quoted market prices from an active market. During the year-ended October 31, 2022: • Trading assets of $705 • Trading assets of $2,099 During the year-ended October 31, 2021: • Trading assets of $10,045 million, investment securities of $3,407 million and obligations related to securities sold short of $2,550 million were transferred out of Level 2 into Level 1. • Trading assets of $9,972 million, investment securities of $13,522 million and obligations related to securities sold short of $2,235 million were transferred out of Level 1 into Level 2. The following significant transfers made between Levels 2 and 3 were based on whether the fair value was determined using significant unobservable inputs. During the year-ended October 31, 2022: • Investments in other foreign governments’ debt of $ million and financial liabilities During the year-ended October 31, 2021: • Trading equity securities of $72 million were transferred out of Level 2 into Level 3.

(2) The valuation of private equity securities utilizes net asset values as reported by fund managers. Net asset values are not considered observable as the Bank cannot redeem these instruments at such values. The range for net asset values per unit or price per share has not been disclosed for these instruments since the valuations are not model-based. The Bank applies judgment in determining unobservable inputs used to calculate the fair value of Level 3 instruments. The following section discusses the significant unobservable inputs for Level 3 instruments. General Partner (GP) Valuations per Net Asset Value Net asset values provided by GPs represent the fair value of investments in private equity securities. Correlation Correlation becomes an input into equity derivative pricing when the relationship between price movements of two or more of the underlying assets is relevant. Volatility Volatility for equity derivatives is a measure of asset price fluctuation. Interest rate volatility measures variability of a security yield or interest rate. Historic volatility is often calculated as the annualized standard deviation of daily price or yield variation for a given time period. Implied volatility is such that, when input into an option pricing model, returns a value equal to the current market value of the option. Forward curves Monthly forward curves for commodity contracts are required inputs to valuation. A portion of the forward curves are unobservable.

Financial Instruments Designated at Fair Value Through Profit or Loss	9 Financial Instruments Designated at Fair Value Through Profit or Loss In accordance with its risk management strategy, the Bank has elected to designate certain senior note liabilities at fair value through profit or loss to reduce an accounting mismatch between fair value changes in these instruments and fair value changes in related derivatives, and where a hybrid financial liability contains one or more embedded derivatives that are not closely related to the host contract. Changes in fair value of financial liabilities arising from the Bank’s own credit risk are recognized in other comprehensive income, without subsequent reclassification to net income. The cumulative fair value adjustment due to own credit risk is determined at a point in time by comparing the present value of expected future cash flows over the term of these liabilities discounted at the Bank’s effective funding rate, and the present value of expected future cash flows discounted at a benchmark rate. The following table presents the fair value of financial liabilities designated at fair value through profit or loss and their changes in fair value.

Credit risk arises from the possibility that counterparties may default on their obligations to the Bank. However, whereas the credit risk of other financial assets is represented by the principal amount net of any applicable allowance for credit losses, the credit risk associated with derivatives is normally a small fraction of the notional amount of the derivative instrument. Derivative contracts generally expose the Bank to credit loss if changes in market rates affect a counterparty’s position unfavourably and the counterparty defaults on payment. Accordingly, exposure to credit risk of derivatives is represented by the positive fair value of the instrument. Negotiated over-the-counter The Bank strives to limit credit risk by dealing with counterparties that it believes are creditworthy, and investment grade counterparties account for a significant portion of the credit risk exposure arising from the Bank’s derivative transactions as at October 31, 2022. To control credit risk associated with derivatives, the Bank uses similar credit risk management activities and procedures to the approaches used in the lending business in assessing and adjudicating exposure. The Bank utilizes a risk metric, potential future exposure (PFE) for derivatives, to measure utilization against established credit limits to the counterparty. PFE measures the effect that changes in the market have on derivative exposures throughout the lifetime of the counterparties’ trades. Additionally, PFE considers risk mitigants such as netting and collateralization. PFE limits and utilization for derivatives counterparties are authorized and monitored by the Bank’s risk management unit. The Bank obtains the benefit of netting by entering into master netting arrangements with counterparties (typically industry standard International Swaps and Derivatives Association (ISDA) agreements), which allow for a single net settlement of all transactions covered by that agreement in the event of a default or early termination of the transactions. In this manner, the credit risk associated with favourable contracts is eliminated by the master netting arrangement to the extent that unfavourable contracts with the same counterparty are not settled before favourable contracts. Collateralization is typically documented by way of an ISDA Credit Support Annex (CSA), the terms of which may vary according to each party’s view of the other party’s creditworthiness. CSAs can require one party to post initial margin at the onset of each transaction. CSAs also allow for variation margin to be called if total uncollateralized mark-to-market bi-lateral in-the-money). Derivative instruments used by the Bank include credit derivatives in its investment and loan portfolios: credit protection is sold as an alternative to acquiring exposure to bond or loan assets, and bought to manage or mitigate credit exposures. The following table summarizes the credit exposure of the Bank’s derivative financial instruments. The credit risk amount (CRA) represents the estimated replacement cost, or positive fair value, for all contracts. CRA takes into account master netting or collateral arrangements that have been made 1 The credit equivalent amount (CEA) is the exposure at default (EAD) prescribed in the Capital Adequacy Requirements (CAR) Guidelines of the Office of the Superintendent of Financial Institutions (OSFI). The risk-weighted asset is calculated by multiplying the CEA by the capital requirement (K) times 12.5, where K is a function of the probability of default (PD), loss given default (LGD), maturity and prescribed correlation factors. Other derivative contracts – other includes precious metals other than gold, and other commodities, including energy and base metal derivatives. 2022 2021 As at October 31 ($ millions) Notional amount Credit risk (1) Credit (1) Risk- Notional amount Credit risk (1) Credit (1) Risk- Interest rate contracts Futures $ 205,283 $ – $ 10 $ – $ 123,348 $ – $ 18 $ 1 Forward rate agreements 132,996 311 93 55 219,841 32 125 68 Swaps 5,714,698 4,331 7,655 589 4,361,426 3,951 4,760 1,120 Options purchased 39,321 183 179 50 40,860 70 44 10 Options written 44,567 – 7 1 41,785 – 11 3 6,136,865 4,825 7,944 695 4,787,260 4,053 4,958 1,202 Foreign exchange and gold contracts Futures 14,880 – 253 5 15,798 – 148 3 Spot and forwards 487,713 1,784 5,834 1,425 427,006 1,604 4,455 1,404 Swaps 695,454 2,147 10,330 2,273 570,175 1,128 7,287 1,660 Options purchased 25,783 472 638 172 16,256 351 247 118 Options written 26,716 – 16 3 16,495 – 14 2 1,250,546 4,403 17,071 3,878 1,045,730 3,083 12,151 3,187 Other derivative contracts Equity 119,962 636 6,534 968 145,352 1,423 9,707 1,340 Credit 27,034 271 415 136 27,421 197 304 59 Commodity and other contracts 62,788 2,636 9,057 649 61,329 4,562 6,610 1,182 209,784 3,543 16,006 1,753 234,102 6,182 16,621 2,581 Credit Valuation Adjustment – – – 6,422 – – – 3,957 Total derivatives $ 7,597,195 $ 12,771 $ 41,021 $ 12,748 $ 6,067,092 $ 13,318 $ 33,730 $ 10,927 Amount settled through central counterparties (2) Exchange-traded 307,076 – 8,110 175 226,695 – 5,200 123 Over-the-counter 5,473,700 – 4,175 83 4,239,877 – 849 17 $ 5,780,776 $ – $ 12,285 $ 258 $ 4,466,572 $ – $ 6,049 $ 140 (1) The amounts presented are net of collateral and master netting agreements at the product level.

Average fair value amounts are based on the latest 13 month-end (2) Master netting agreement amounts are based on the capital adequacy criteria of the Basel Committee on Banking Supervision (BCBS) and OSFI. These criteria allow netting where there are legally enforceable contracts which enable net settlement in the event of a default, bankruptcy, liquidation or similar circumstances. (e) Hedging activities The Bank manages interest rate risk, foreign currency risk and equity risk through hedge accounting transactions Interest rate risk Single-currency interest rate swaps are used to hedge interest rat e Foreign currency risk In fair value hedges, cross-currency swaps and single-currency interest rate swaps are used to manage foreign currency exposure in conjunction with interest rate exposure. Cross-currency interest rate swaps or a combination of cross-currency basis swaps and single-currency interest rate swaps are mainly used to convert a foreign currency fixed rate exposure to a functional currency floating rate exposure. In hedges of both foreign currency and interest rate exposure, the interest rate risk is generally hedged only to the extent of the benchmark interest rate. In cash flow hedges, cross-currency interest rate swaps, single-currency interest rate swaps, foreign currency forwards and foreign currency assets or liabilities are used to manage foreign currency exposure, or a combined foreign currency and interest rate exposure. Cross-currency interest rate swaps are used to offset the foreign currency exposure by exchanging the interest cash flows in one currency to another currency. Single-currency interest rate swaps may be used in conjunction with cross-currency swaps to convert the foreign currency exposure or resulting functional currency exposure from floating to fixed. Foreign currency forwards and foreign currency denominated assets and liabilities are used to offset the exposure arising from highly probable future cash flows, including purchase considerations for business acquisitions and sale proceeds for business divestitures that are denominated in a foreign currency. In hedges of both foreign currency and interest rate exposure, the interest rate risk is generally hedged only to the extent of the benchmark interest rate. In net investment hedges, the Bank designates foreign currency liabilities and foreign currency forwards as hedging instruments to manage foreign currency exposure. The designated non-derivative Equity risk Equity risk is created by the Bank’s share-based compensation plans awarded to employees. In cash flow hedges, total return swaps are mainly used to offset the equity exposure by exchanging interest payments for payments based on the returns on the underlying shares. For all of the risks identified above, the economic relationship and hedge ratio are determined using a qualitative and quantitative assessment. This assessment incorporates comparison of critical terms of the hedged and hedging item, and regression analysis. For regression analysis, a hedging relationship is considered highly effective when all of the following criteria are met: correlation between the variables in the regression is at least 0.8 or greater; slope of the regression is within a 0.8-1.25 • The use of different discount curves to value the hedged item and the hedging derivative in fair value hedges, in order to reflect the reduced credit risk of collateralized derivatives; • Differences in key terms such as the underlying reference interest rate tenor, reset/settlement frequency and floating spread between the hedging instruments and the hedged item. The Bank has elected to continue to apply the hedge accounting requirements of IAS 39. However, the Bank has implemented the additional hedge accounting disclosures that are required by the IFRS 9 related amendments to IFRS 7 “ Financial Instruments: Disclosures The following table summarizes the notional amounts of derivatives and carrying amounts of cash and deposit liabilities designated as hedging instruments. 2022 2021 Notional amounts (1) Notional amounts (1) Remaining term to maturity Remaining term to maturity As at October 31 ($ millions) Within one year One to five years Over five years Total Within one year One to five years Over five years Total Fair value hedges Interest rate risk – swaps $ 35,535 $ 89,709 $ 17,588 $ 142,832 $ 21,850 $ 127,350 $ 14,489 $ 163,689 Foreign currency/interest rate risk – swaps – – – – – 11 – 11 Cash flow hedges Interest rate risk – swaps 18,267 69,933 34,180 122,380 34,489 62,934 28,754 126,177 Foreign currency/interest rate risk – swaps 16,886 17,628 8,527 43,041 16,906 23,224 7,645 47,775 Foreign currency risk Swaps 47,525 89,863 28,745 166,133 29,002 54,434 14,425 97,861 Foreign currency forwards 14,699 – – 14,699 10,510 – – 10,510 Cash 77 – – 77 66 – – 66 Equity risk – total return swaps 270 603 – 873 316 649 – 965 Net investment hedges Foreign currency risk Foreign currency forwards 24,038 – – 24,038 18,132 – – 18,132 Deposit liabilities 6,289 – – 6,289 5,714 – – 5,714 Total $ 163,586 $ 267,736 $ 89,040 $ 520,362 $ 136,985 $ 268,602 $ 65,313 $ 470,900 (1) Notional amounts relating to derivatives that are hedging multiple risks in both assets and liabilities are included in more than one category.

(e) Allowance for credit losses (i) Key inputs and assumptions The Bank’s allowance for credit losses is measured using a three-stage approach based on the extent of credit deterioration since origination. The calculation of the Bank’s allowance for credit losses is an output of complex models with a number of underlying assumptions regarding the choice of variable inputs and their interdependencies. Some of the key drivers include the following: • Changes in risk ratings of the borrower or instrument reflecting changes in their credit quality; • Changes in the volumes of transactions; • Changes in the forward-looking macroeconomic environment reflected in the variables used in the models such as GDP growth, unemployment rates, commodity prices, and house price indices, which are most closely related with credit losses in the relevant portfolio; • Changes in macroeconomic scenarios and the probability weights assigned to each scenario; and • Borrower migration between the three stages. The Bank determines its allowanc e The Bank considers both internal and external sources of information and data to achieve unbiased projections and forecasts in determining the allowance for credit losses. The Bank prepares the scenarios using forecasts generated by Scotiabank Economics (SE). The forecasts are generated using models whose outputs are modified by SE as necessary to formulate a ‘base case’ view of the most probable future direction of economic developments. The development of the base case and alternative scenarios is overseen by a governance committee that consists of internal stakeholders from across the Bank. The final base case and alternative scenarios reflect significant review and oversight, and incorporate judgment both in the determination of the scenarios’ forecasts and the probability weights that are assigned to them. (ii) Key macroeconomic variables The inputs and models used for calculating expected credit losses may not always capture all characteristics of the market at the date of the financial statements. Qualitative adjustments or overlays may be made for certain portfolios or geographies as temporary adjustments in circumstances where, in the Bank’s view, the inputs, assumptions, and/or modelling techniques do not capture all relevant risk factors, including the emergence of economic or geopolitical events up to the date of financial statements. The Bank has applied expert credit judgement in the assessment of underlying credit deterioration and migration of balances to progressive stages. The Bank considered both quantitative and qualitative information in the assessment of significant increase in credit risk. The Bank’s models are calibrated to consider past performance and macroeconomic forward-looking variables as inputs. The Bank has generated a forward-looking base case scenario and three alternate forward-looking scenarios (one optimistic and two pessimistic) as key inputs into the expected credit loss provisioning models. The global economic outlook has deteriorated over the last year owing to the combined impacts of central bank efforts to tame inflation, the consequences of Russia’s war on Ukraine, pandemic management in China and the impact of higher energy prices. Concerns about potential slowdown and high inflation have led to very volatile financial markets, which have clouded the outlook further. Therefore, the base case scenario is less favourable this year. Relative to the base case, the optimistic scenario features somewhat stronger economic activity. The two pessimistic scenarios were updated around the potential risk of stagflation and recession. In light of current economic uncertainty, the pessimistic scenarios feature a protracted period of high commodity prices, elevated financial market uncertainty and a further disruption to supply chains. All these elements lead to much higher inflation compared to the base case scenario resulting in a rapid deceleration of growth. In the pessimistic scenario, stagflation is short-lived, while in the very pessimistic scenario, the stagflation shock is strong and persists for a longer period of time. The Bank increased the weight of the pessimistic scenarios in calculating the allowance for credit losses on performing loans to capture the elevated downside risk and uncertainty to the outlook. The following tables show certain key macroeconomic variables used to calculate the modelled estimate for the allowance for credit losses.

If we were to only use our very pessimistic scenario for the measurement of allowance for credit losses for such assets, our allowance for credit losses on performing financial instruments would be Under our current probability-weighted scenarios, if all of our performing financial assets were in Stage 1, reflecting a 12 month expected loss period, the allowance for credit losses would be $521 million (2021 – $407 million) lower than the reported allowance for credit losses on performing financial assets.

Derecognition of Financial Assets	14 Derecognition of Financial Assets Securitization of residential mortgage loans The Bank securitizes fully insured residential mortgage loans, Bank originated and others, through the creation of mortgage-backed securities (MBS) under the National Housing Act (NHA) MBS program, sponsored by Canada Mortgage and Housing Corporation (CMHC). MBS created under the program are primarily sold to Canada Housing Trust (the Trust), a government sponsored entity, under the Canada Mortgage Bond (CMB) program, and/or third-party investors. The Trust issues securities to third-party investors. The CMHC also previously purchased insured mortgage pools from the Bank under the Insured Mortgage Purchase Program (IMPP). The sale of mortgages under the above programs does not meet the derecognition requirements, where the Bank retains the pre-payment The transferred mortgages continue to be recognized on the Consolidated Statement of Financial Position as residential mortgage loans. Cash proceeds from the transfer are treated as secured borrowings and included in Deposits – Business and government on the Consolidated Statement of Financial Position. The following table provides the carrying amount of transferred assets that do not qualify for derecognition and the associated liabilities: As at October 31 ($ millions) 2022 (1) 2021 (1) Assets Carrying value of residential mortgage loans $ 15,032 $ 17,145 Other related assets (2) 9,854 9,787 Liabilities Carrying value of associated liabilities 24,173 25,833 (1) The fair value of the transferred assets is $23,379 (2021 – $25,761) and the fair value of the associated liabilities is $23,254 (2021 – $26,021), for a net position of $125 (2021 – $(260)). (2) These include cash held in trust and trust permitted investment assets, including repurchase style transactions of mortgage-backed securities, acquired as part of principal reinvestment account that the Bank is required to maintain in order to participate in the programs. Securitization of personal lines of credit, credit cards and auto loans The Bank securitizes a portion of its credit card and auto loan receivables through consolidated structured entities. These receivables continue to be recognized on the Consolidated Statement of Financial Position as personal loans and credit card loans. For further details, refer to Note 15. Securities sold under repurchase agreements and securities lent The Bank enters into transactions, such as repurchase agreements and securities lending agreements, where the Bank transfers assets under agreements to repurchase them on a future date and retains all the substantial risks and rewards associated with the assets. The transferred assets remain on the Consolidated Statement of Financial Position. The following table provides the carrying amount of the transferred assets and the associated liabilities: As at October 31 ($ millions) 2022 (1) 2021 (1) Carrying value of assets associated with: Repurchase agreements (2) $ 122,552 $ 100,083 Securities lending agreements 52,178 59,506 Total 174,730 159,589 Carrying value of associated liabilities (3) $ 139,025 $ 123,469 (1) The fair value of transferred assets is $174,730 (2021 – $159,589) and the fair value of the associated liabilities is $139,025 (2021 – $123,469), for a net position of $35,705 (2021 – $36,120).

These loans are derecognized from the Consolidated Statement of Financial Position as the program meets the pass-through criteria for derecognition of financial assets under IFRS 9. As at October 31, 2022, the Bank has derecognized $3.9 billion of CEBA loans (October 31, 2021 – $4.3 billion).

Structured Entities

Structured Entities	12 Months Ended

Text Block [Abstract]
Structured Entities	15 Structured Entities (a) Consolidated structured entities U.S. multi-seller conduit The Bank-sponsored U.S. multi-seller conduit purchases high-quality financial assets from independent third parties (the sellers) funded by the issuance of highly rated asset-backed commercial paper. The sellers continue to service the financial assets and provide credit enhancements through overcollateralization protection and cash reserves. Each asset purchased by the conduit has a deal-specific liquidity facility provided by the Bank in the form of a Liquidity Asset Purchase Agreement (LAPA). The primary purpose of the LAPA is to provide an alternative source of financing in the event the conduit is unable to access the asset-backed commercial paper market. The administration agent can require the Bank in its capacity as liquidity provider to purchase an interest in the related assets owned by the conduit. The Bank is not obligated to perform under the LAPA agreements in the event the conduit itself is insolvent. The Bank’s liquidity agreements with the conduit call for the Bank to fund full par value of the assets, including defaulted assets, if any, of the conduit. This facility is available to absorb the losses on defaulted assets, if any, in excess of losses absorbed by deal-specific seller credit enhancements. Further, the Bank holds the subordinated note issued by the conduit. The Bank’s exposure from the U.S. conduit through the LAPA, including the obligation to purchase defaulted assets and investment in the conduit’s subordinated note, give the Bank the obligation to absorb losses that could potentially be significant to the conduit, which in conjunction with power to direct the conduit’s activities, result in the Bank consolidating the U.S. multi-seller conduit. The conduit’s assets of $10 billion (2021 – $5 billion) are primarily included in Business and government loans on the Bank’s Consolidated Statement of Financial Position. There are contractual restrictions on the ability of the Bank’s consolidated U.S. multi-seller conduit to transfer funds to the Bank. The Bank is restricted from accessing the conduit’s assets under the relevant arrangements. The Bank has no rights to the assets owned by the conduit. In the normal course of business, the assets of the conduit can only be used to settle the obligations of the conduit. Bank funding vehicles and capital vehicles The Bank uses funding and capital vehicles to facilitate cost-efficient financing of its own operations, including the issuance of covered bonds and notes. Activities of funding structured entities are generally limited to holding an interest in a pool of assets or receivables generated by the Bank. Capital vehicles include Scotiabank LRCN Trust which was established in connection with the Bank’s issuance of qualifying regulatory capital instruments. These structured entities are consolidated due to the Bank’s decision-making power and ability to use that power to affect the Bank’s returns. Covered bonds The Bank has a registered covered bond program through which it issues debt that is guaranteed by Scotiabank Covered Bond Guarantor Limited Partnership (the “LP”). Under this program, the LP purchases uninsured residential mortgages from the Bank, which it acquires with funding provided by the Bank. As at October 31, 2022, $45.9 billion (2021 – $31.3 billion) covered bonds were outstanding and included in Deposits – Business and government on the Consolidated Statement of Financial Position. The Bank’s outstanding covered bonds are denominated in U.S. dollars, Australian dollars, British pounds, Swiss francs and Euros. As at October 31, 2022, assets pledged in relation to these covered bonds were uninsured residential mortgages denominated in Canadian dollars of $51.4 billion (2021 – $34.7 billion). These figures exclude activities in connection with Canadian dollar-denominated covered bonds held by the Bank and that are eliminated upon consolidation or that are transferred to the Bank of Canada as part of its term repo program. Credit card receivables securitization trust The Bank securitizes a portion of its Canadian credit card receivables through a Bank-sponsored structured entity. This entity issues senior and subordinated notes to third-party investors and the proceeds of such issuance are used to purchase co-ownership The Bank is responsible for servicing the transferred credit card receivables as well as performing administrative functions for this entity. As at October 31, 2022, US$0.8 billion ($1.1 billion Canadian dollar equivalent) (2021 – US$1.3 billion, $1.5 billion Canadian dollar equivalent) Class A notes; and US$70 million ($95 million Canadian dollar equivalent dollar equivalent at Auto loan receivables securitization trusts The Bank securitizes a portion of its Canadian auto loan receivables through Bank-sponsored structured entities. The entities issue senior and subordinated notes to the Bank and/or third-party investors, and the proceeds of such issuances are used to purchase discrete pools of retail indirect auto loan receivables from the Bank. Recourse of the note holders is limited to the auto loan receivables. The Bank is responsible for servicing the transferred auto loan receivables as well as performing administrative functions for the entities. As at October 31, 2022, the aggregate senior and subordinated notes issued to third parties outstanding and included in Deposits – Business and government on the Consolidated Statement of Financial Position were US$15.7 million million dollar equivalent million million dollar equivalent million million Scotiabank LRCN Trust The Bank sponsors the Scotiabank LRCN Trust established in connection with the issuance of limited recourse capital notes. As at October 31, 2022, $4,526 million (2021 – $2,003 million) capital notes were outstanding and included in Preferred shares and other equity instruments on the Consolidated Statement of Financial Position. Refer to Note 24(b) – Preferred shares and other equity instruments for further information. Other Assets of other consolidated structured entities are comprised of securities, deposits with banks and other assets to meet the Bank’s and customer needs. (b) Unconsolidated structured entities The following table provides information about other structured entities which the Bank does not control and therefore does not consolidate. As at October 31, 2022 ($ millions) Canadian multi-seller Structured Capital Total Total assets on structured entity’s financial statements $ 3,773 $ 2,304 $ 833 $ 6,910 Assets recognized on the Bank’s financial statements Trading assets 35 2 – 37 Investment securities – 885 10 895 Loans (1) – 704 59 763 35 1,591 69 1,695 Liabilities recognized on the Bank’s financial statements Deposits – Business and government – – 833 833 – – 833 833 Bank’s maximum exposure to loss $ 3,808 $ 1,591 $ 69 $ 5,468 As at October 31, 2021 ($ millions) Canadian multi-seller Structured Capital Total Total assets (on structured entity’s financial statements) $ 3,519 $ 2,403 $ 833 $ 6,755 Assets recognized on the Bank’s financial statements Trading assets 7 2 – 9 Investment securities – 1,124 10 1,134 Loans (1) – 639 59 698 7 1,765 69 1,841 Liabilities recognized on the Bank’s financial statements Deposits – Business and government – – 833 833 – – 833 833 Bank’s maximum exposure to loss $ 3,526 $ 1,765 $ 69 $ 5,360 (1) Loan balances are presented net of allowance for credit losses. The Bank’s maximum exposure to loss represents the notional amounts of guarantees, liquidity facilities, and other credit support relationships with the structured entities, the credit risk amount for certain derivative contracts with the entities and the amount invested where the Bank holds an ownership interest in the structured entities. Of the aggregate amount of maximum exposure to loss as at October 31, 2022, the Bank has recorded $1.7 billion (2021 – $1.8 billion), primarily its interest in the structured entities, on its Consolidated Statement of Financial Position. Canadian multi-seller conduits that the Bank administers The Bank sponsors two Canadian multi-seller conduits. The conduits purchase assets from independent third parties (the sellers) funded by the issuance of asset-backed commercial paper. The sellers continue to service the assets and provide credit enhancements through overcollateralization protection and cash reserves. The Bank has no rights to these assets as they are available to support the obligations of the respective programs but manages for a fee the commercial paper selling programs. To ensure timely repayment of the commercial paper, each asset pool financed by the multi-seller conduits has a deal-specific LAPA with the Bank. Pursuant to the terms of the LAPA, the Bank as the liquidity provider is obligated to purchase non-defaulted Although the Bank has power over the relevant activities of the conduits, it has limited exposure to variability in returns, which results in the Bank not consolidating the two Canadian conduits. Structured finance entities The Bank has interests in structured entities used to assist corporate clients in accessing cost-efficient financing through their securitization structures. The Bank may act as an administrator, an investor or a combination of both in these types of structures. Capital funding vehicles These entities are designed to pass the Bank’s credit risk to the holders of the securities. Therefore, the Bank does not have exposure or rights to variable returns from these unconsolidated entities. (c) Other unconsolidated Bank-sponsored entities The Bank sponsors unconsolidated structured entities including mutual funds, in which it has insignificant or no interest at the reporting date. The Bank is a sponsor when it is significantly involved in the design and formation at inception of the structured entities, and the Bank’s name is used by the structured entities to create an awareness of the instruments being backed by the Bank’s reputation and obligation. The Bank also considers other factors, such as its As at October 31, 2022, the bank earned $2,486 million (2021 – $2,604 million) in revenue from unconsolidated Bank-sponsored mutual fund entities.

Goodwill is assessed for impairment annually or more frequently if events or circumstances occur that may result in the recoverable amount of the CGU falling below its carrying value. The Bank determines the carrying value of the CGU using a regulatory capital approach based on credit, market, operational risks and leverage, consistent with the Bank’s capital attribution for business line performance measurement. The recoverable amount is the higher of fair value less costs of disposal and value in use. The recoverable amount for the CGU has been determined using the fair value less costs of disposal method. In arriving at such value for the CGU, the Bank has used price earnings (P/E) multiples applied to normalized net income for the last four quarters as of the test date. A control premium is added based on a five year weighted average acquisition premium paid for comparable companies, and costs of disposal are deducted from the fair value of the CGU. The resulting recoverable amount determined for the CGU is then compared to its respective carrying amount to identify any impairment. P/E multiples ranging from 9.0 to 12.0 times (2021 – 10.0 to 12.5 times) have been used. The fair value less costs of disposal of the CGU is sensitive to changes in net income, P/E multiples and control premiums. Goodwill was assessed for annual impairment as at July 31, 2022 and July 31, 2021 and no impairment was determined to exist. Management believes that reasonable negative changes in any one key assumption used to determine the recoverable amount of the CGU would not result in an impairment. No significant negative changes were noted as of October 31, 2022. Intangible assets Intangible assets consist of assets with indefinite and finite useful lives.

Impairment testing of indefinite life intangible assets Indefinite life intangible assets are not amortized and are assessed for impairment annually or more frequently if events or changes in circumstances indicate that the asset may be impaired. Impairment is assessed by comparing the carrying value of the indefinite life intangible asset to its recoverable amount. The recoverable amount of the fund management contracts is based on a value in use approach using the multi-period excess earnings method. This approach uses cash flow projections from management-approved financial budgets which include key assumptions related to market appreciation, net sales of funds, and operating margins taking into consideration past experience and market expectations. The forecast cash flows cover a 5-year 4.5 applied thereafter. These cash flows have been discounted at 10% (2021 – . Indefinite life intangible assets were assessed for annual impairment as at July 31, 2022 and July 31, 2021 and no impairment was determined to exist. Management believes that reasonable negative changes in any one key assumption used to determine the recoverable amount would not result in an impairment. No significant negative changes were noted as of October 31, 2022.

These efficiencies are a result of the Bank’s commitment to simplify processes and optimize distribution channels to run businesses more effectively while meeting changing customer needs. This charge was recorded in the Other operating segment. Legal In the ordinary course of business, the Bank and its subsidiaries are routinely defendants in, or parties to a number of pending and threatened legal actions and regulatory proceedings, including actions brought on behalf of various classes of claimants. In view of the inherent difficulty of predicting the outcome of such matters, the Bank cannot state what the eventual outcome of such matters will be. However, based on current knowledge, management does not believe that liabilities, if any, arising from pending litigation or regulatory proceedings will have a material adverse effect on the Consolidated Statement of Financial Position or results of operations of the Bank. Legal provisions are established when it becomes probable that the Bank will incur an expense related to a legal action and the amount can be reliably estimated. Such provisions are recorded at the best estimate of the amount required to settle any obligation related to these legal actions as at the balance sheet date, taking into account the risks and uncertainties surrounding the obligation. Management and internal and external experts are involved in estimating any amounts that may be required. The actual costs of resolving these claims may vary significantly from the amount of the legal provisions. The Bank’s estimate involves significant judgement, given the varying stages of the proceedings, the fact that the Bank’s liability, if any, has yet to be determined and the fact that the underlying matters will change from time to time. As such, there is a possibility that the ultimate resolution of those legal actions may be material to the Bank’s consolidated results of operations for any particular reporting period. The Bank, through its Peruvian subsidiary, is engaged in legal actions related to certain value-added tax assessed amounts and associated interest totaling $165 million, which arose from certain client transactions which occurred prior to the Bank’s acquisition of the subsidiary. The legal action in Peru related to the original assessed amount continues. In November 2021, the Peruvian Constitutional Court dismissed the matter relating to the accrued interest for procedural reasons. With respect to this interest component, in October 2022, the Bank filed a request for arbitration against the Republic of Peru before the International Centre for the Settlement of Investment Disputes, pursuant to the provisions of the Canada-Peru Free Trade Agreement. The claim arises out of the Constitutional Court of Peru’s inequitable treatment of Scotiabank Peru’s rights in breach of the Canada-Peru Free Trade Agreement. The Bank is confident that it will be successful in these matters and intends to continue to defend its position. Accordingly, no amounts have been accrued in the consolidated financial statements. Prior Years In the prior year, the Bank recorded settlement and litigation provisions in the amount of $62 million in connection with the Bank’s former metals business. These provisions were recorded in the Other operating segment. On August 19, 2020, the Bank entered into a Deferred Prosecution Agreement (“DPA”) with the U.S. Department of Justice (the “DOJ”). Additionally, the Commodity Futures Trading Commission (the “CFTC”) issued three separate orders against the Bank (collectively, the “Orders”). The DPA and the Orders (together, the “Resolutions”) resolve the DOJ’s and CFTC’s investigations into the Bank’s activities and trading practices in the metals markets and related conduct as well as pre-trade mid-market marks and related swap dealer compliance issues. Under the terms of the Resolutions, the Bank made aggregate payments to the DOJ and CFTC of approximately $127.5 million (USD) and has agreed to retain an independent compliance monitor, which the Bank engaged on April 1, 2021. Under one of the orders, the CFTC will defer proceedings to suspend or revoke the Bank’s provisional registration as a swap dealer subject to the Bank’s implementation of a remediation plan, among other conditions, which the Bank is carrying out under the oversight of the independent compliance monitor, which commenced its engagement in April 2021, and which is expected to last three years under the terms of the Resolutions.

Contractual NVCC provisions contained in the Bank’s Subordinated Additional Tier 1 Capital Notes, including those issued to Scotiabank LRCN Trust as recourse assets in respect of the LRCNs, trigger conversion of these securities into a variable number of common shares if OSFI announces that the Bank has ceased, or is about to cease, to be viable, or if a federal or provincial government in Canada publicly announces that the Bank has accepted or agreed to accept a capital injection, or equivalent support, from the federal government or any provincial government or political subdivision or agent thereof without which the Bank would have been determined by OSFI to be non-viable. (10-day The notes above have been determined to be compound instruments that have both equity and liability features. At inception, the fair value of the liability component is initially measured with any residual amount assigned to the equity component. On the respective dates of issuance, the Bank has assigned an insignificant value to each liability component of the notes and, as a result, the proceeds received upon issuance of the notes have been presented as equity. The Bank will continue to monitor events that could impact the value of the liability component. During the year ended October 31, 2022, the Bank paid aggregate distributions on these notes of $239 million (2021 – $162 million), net of income taxes of $30 million (2021 – $4 million), based on exchange rates in effect on the payment dates , where applicable. (c) Restrictions on payment of dividends and retirement of shares Under the Bank Act, the Bank is prohibited from declaring any dividends on its common or preferred shares or redeeming, purchasing or otherwise retiring such shares when the Bank is, or would be placed by such a declaration or retirement, in contravention of the capital adequacy, liquidity or any other regulatory directives issued under the Bank Act. In the event that applicable cash distributions on any of the Scotiabank Trust Securities are not paid on a regular distribution date, the Bank has undertaken not to declare dividends of any kind on its preferred or common shares until such distributions are made in full or the twelfth month following the non-payment In the event that distributions are not paid in full on the Bank’s Subordinated Additional Tier 1 Capital Notes (NVCC), including those issued as recourse assets in respect of LRCNs to Scotiabank LRCN Trust where the trustee has not waived such distributions or no longer holds the respective AT1 Notes, the Bank has undertaken not to declare dividends on its common or preferred shares or redeem, purchase or otherwise retire such shares until the month commencing after such distributions have been made in full. In the event that dividends to which preferred shareholders are then entitled have not been paid or sufficient funds have not been set aside to do so, the Bank has undertaken not to declare dividends on its common shares or redeem, purchase or otherwise retire its common shares. On March 13, 2020, OSFI advised federally regulated deposit taking institutions to suspend buybacks and increases to dividends in respect of its common shares as part of COVID-19 COVID-19 Currently, the above limitations do not restrict the payment of dividends on or retirement of preferred or common shares.

Capital Management	25 Capital Management The primary regulator over the Bank’s consolidated capital adequacy is the Office of the Superintendent of Financial Institutions, Canada (OSFI). The capital adequacy regulations in Canada are largely consistent with international standards set by the Basel Committee on Banking Supervision (BCBS). OSFI requires Canadian deposit-taking institutions to fully implement the 2019 Basel III reforms and achieve minimums of 7%, 8.5% and 10.5% for CET1, Tier 1 and Total Capital, respectively. OSFI has also designated the Bank as a domestic systemically important bank (D-SIB), In addition, OSFI expects D-SIBs The Bank’s regulatory capital ratios were as follows: As at October 31 ($ millions) 2022 2021 Capital (1) Common Equity Tier 1 capital $ 53,081 $ 51,010 Net Tier 1 capital 61,262 57,915 Total regulatory capital 70,710 66,101 Total loss absorbing capacity (TLAC) (2) 126,565 115,681 Risk-weighted assets/exposures used in calculation of capital ratios Risk-weighted assets (1) $ 462,448 $ 416,105 Leverage exposures ( 3 1,445,619 1,201,766 Regulatory ratios (1) Common Equity Tier 1 capital ratio 11.5 % 12.3 % Tier 1 capital ratio 13.2 % 13.9 % Total capital ratio 15.3 % 15.9 % Total loss absorbing capacity ratio (2) 27.4 % 27.8 % Leverage ratio (3) 4.2 % 4.8 % Total loss absorbing capacity leverage ratio (2) 8.8 % 9.6 % (1) This measure has been disclosed in this document in accordance with OSFI Guideline – Capital Adequacy Requirements (November 2018).

Share-Based Payments	26 Share-Based Payments (a) Stock option plans The Bank grants stock options as part of the employee Stock Option Plan as well as stand-alone stock appreciation rights (SARs). Options to purchase common shares and/or to receive an equivalent cash payment, as applicable, may be granted to select employees at an exercise price of the higher of the closing price of the Bank’s common shares on the TSX on the trading day prior to the grant date or the volume weighted average trading price for the five trading days immediately preceding the grant date. Stock options granted since December 2014 vest 50% at the end of the third year and 50% at the end of the fourth year. This change is prospective and does not impact prior period grants. Stock options are exercisable no later than 10 years after the grant date. In the event that the expiry date falls within an insider trading blackout period, the expiry date will be extended for 10 business days after the end of the blackout period. An additional 12 million common shares have been reserved for issuance under the Bank’s employee Stock Option Plan as approved by the shareholders at the Annual General Meeting held in April 2022. There is a total of 141 million common shares which have been reserved for issuance under the Bank’s employee Stock Option Plan of which The cost of these options is recognized on a graded vesting basis except where the employee is eligible to retire prior to a tranche’s vesting date, in which case the cost is recognized between the grant date and the date the employee is eligible to retire. The Stock Option Plan includes: • Stock options Employee stock options granted are equity-classified stock options which call for settlement in shares. The amount recorded in equity – other reserves for vested stock options as at October 31, 2022 was $104 million (2021 – $111 million). In 2022, an expense of $10 million (2021 – $7 million) was recorded in salaries and employee benefits in the Consolidated Statement of Income. As at October 31, 2022, future unrecognized compensation cost for non-vested • Stock appreciation rights Stand-alone SARs are granted instead of stock options to select employees in countries where local laws may restrict the Bank from issuing shares. When a SAR is exercised, the Bank pays the appreciation amount in cash equal to the rise in the market price of the Bank’s common shares since the grant date. During fiscal 2022, 85,136 SARs were granted (2021 – 90,392) and as at October 31, 2022, 558,053 SARs were outstanding (2021 – 578,643), of which The share-based payment liability recognized for vested SARs as at October 31, 2022 was $2 million (2021 – $7 million). The corresponding intrinsic value of this liability as at October 31, 2022 was $5 million (2021 – $7 million). In 2022, a benefit of $3 million (2021 – benefit of $1 million) was recorded in salaries and employee benefits in the Consolidated Statement of Income. This benefit is net of $0.1 million losses arising from derivatives used to manage the volatility of share-based payments (2021 – $12 million gains). Determination of fair values The share-based payment liability and corresponding expense for SARs were quantified using the Black-Scholes option pricing model with the following assumptions and resulting fair value per award: As at October 31 2022 2021 Assumptions Risk-free interest rate% 3.31% - 5.00% 0.59% - 1.53% Expected dividend yield 5.98% 4.34% Expected price volatility 17.64% - 27.09% 15.12% - 23.51% Expected life of option 0.05 - 6.11 0.00 - 6.12 years Fair value Weighted-average fair value $ 4.79 $ 14.46 The share-based payment expense for stock options, was quantified using the Black-Scholes option pricing model on the date of grant.

(2) Includes 1,287,242 options originally issued under HollisWealth plans (2021 – nil). (b) Employee share ownership plans Eligible employees can contribute up to a specified percentage of salary towards the purchase of common shares of the Bank. In general, the Bank matches 50-60% As at October 31, 2022, an aggregate of 19 million common shares were held under the employee share ownership plans (2021 – 18 million). The shares in the employee share ownership plans are considered outstanding for computing the Bank’s basic and diluted earnings per share. (c) Other share-based payment plans Other share-based payment plans use notional units that are valued based on the Bank’s common share price on the TSX. Most grants of units accumulate dividend equivalents in the form of additional units based on the dividends paid on the Bank’s common shares. These plans are settled in cash and, as a result, are liability-classified. Fluctuations in the Bank’s share price change the value of the units, which affects the Bank’s share-based payment expense. As described below, the value of the Performance Share Units also varies based on Bank performance. Upon exercise or redemption, payments are made to the employees with a corresponding reduction in the accrued liability. In 2022, an aggregate expense of $328 million (2021 – $218 million) was recorded in salaries and employee benefits in the Consolidated Statement of Income for these plans. This expense includes losses from derivatives used to manage the volatility of share-based payments of $120 million (2021 – $306 million gains). As at October 31, 2022, the share-based payment liability recognized for vested awards under these plans was $763 million (2021 – $887 million). Details of these other share-based payment plans are as follows: Deferred Stock Unit Plan (DSU) Under the DSU Plan, senior executives may elect to receive all or a portion of their cash bonus under the Annual Incentive Plan (which is expensed for the year awarded in salaries and employee benefits in the Consolidated Statement of Income) in the form of deferred stock units which vest immediately. In addition the DSU plan allows for eligible executives of the Bank to participate in grants that are not allocated from the Annual Incentive Plan election. These grants are subject to specific vesting schedules. Units are redeemable in cash only when an executive ceases to be a Bank employee, and must be redeemed by December 31 of the year following that event. As at October 31, 2022, there were 1,890,117 units (2021 – 1,496,911) awarded and outstanding of which 2,760,706 units were vested (2021 – 1,095,062). Directors’ Deferred Stock Unit Plan (DDSU) Under the DDSU Plan, non-officer Restricted Share Unit Plan (RSU) Under the RSU Plan, select employees receive an award of restricted share units which, for the majority of grants, vest at the end of three years. There are certain grants that provide for a graduated vesting schedule. Upon vesting, all RSU units are paid in cash to the employee. The share-based payment expense is recognized evenly over the vesting period except where the employee is eligible to retire prior to the vesting date in which case, the expense is recognized between the grant date and the date the employee is eligible to retire. As at October 31, 2022, there were 5,200,515 units (2021 – 4,342,698) awarded and outstanding of which 3,390,197 were vested (2021 – 2,929,298). Performance Share Unit Plan (PSU) Eligible executives receive an award of performance share units which, for the majority of grants, vest at the end of three years. Certain grants provide for a graduated vesting schedule which includes a specific performance factor calculation. PSU awards are subject to performance criteria measured over a three-year period whereby a multiplier factor is applied which impacts the incremental number of units due to employees. The three-year performance measures include return on equity compared to target and total shareholder return relative to a comparator group selected prior to the granting of the award. The Bank uses a probability-weighted-average of potential outcomes to estimate the multiplier impact. The share-based payment expense is recognized over the vesting period except where the employee is eligible to retire prior to the vesting date; in which case, the expense is recognized between the grant date and the date the employee is eligible to retire. This expense varies based on changes in the Bank’s share price and the Bank’s performance compared to the performance measures. Upon vesting, the units are paid in cash to the employee. As at October 31, 2022, there were 7,525,441 units (2021 – 8,693,704) outstanding subject to performance criteria, of which 11,759,971 units were vested (2021 – 6,467,053).

Included in the net deferred tax asset are tax benefits of $1,420 million (2021 – $164 million) that relate to tax losses incurred in Canadian or foreign operations in either the current or the preceding year. In determining if it is appropriate to recognize these tax benefits, the Bank relied on projections of future taxable profits. The amount of taxable temporary differences associated with investments in subsidiaries, associates and interests in joint ventures for which deferred tax liabilities have not been recognized at October 31, 2022 is approximately $41 billion (2021 – $34 billion). Canadian Tax Matters The Bank received reassessments totaling $1,506 million of tax and interest as a result of the Canada Revenue Agency (CRA) denying the tax deductibility of certain Canadian dividends received during the 2011-2017 taxation years A subsidiary of the Bank has received withholding tax assessments from the CRA in respect of certain of its securities lending transactions for its 2014-2017 taxation years totaling million of tax, penalties, and interest. In respect of both matters the Bank is confident that its tax filing position was appropriate and in accordance with the relevant provisions of the Income Tax Act (Canada) and intends to vigorously defend its position. 2022 Proposed Canadian Federal Tax Measures On August 9, 2022, the Department of Finance released draft legislative proposals relating to tax measures announced in the Federal Budget on April 7, 2022. These tax measures include the Canada Recovery Dividend (“CRD”) under which the Bank will pay a one-time On November 4, 2022, the Fall Economic Statement Implementation Act (Bill C-32) containing these measures was introduced into the legislature for the first reading. On November 22, 2022, Bill C-32 completed its second legislative reading. The impact of these proposed tax measures has not been recognized in the Bank’s financial results as at October 31, 2022 as they are not substantively enacted, which would only occur after the third legislative reading. Once substantively enacted, an income tax expense will be recognized in the Bank’s Consolidated Statement of Income for the entire CRD obligation. The CRD payable is estimated at approximately $640 million.

Employee Benefits	28 Employee Benefits The Bank sponsors a number of employee benefit plans, including pensions (defined benefit and defined contribution) and other benefit plans (post-retirement benefits and other long-term employee benefits) for most of its employees globally. The information presented below relates to the Bank’s principal plans; other plans operated by certain subsidiaries of the Bank are not considered material and are not included in these disclosures. Global pension plans The principal pension plans include plans in Canada, US, Mexico, UK, Ireland, Jamaica, Trinidad & Tobago and other countries in the Caribbean in which the Bank operates. The Bank has a strong and well defined governance structure to manage these global obligations. The investment policy for each principal plan is reviewed periodically and all plans are in good standing with respect to legislation and local regulations. Actuarial valuations for funding purposes for the Bank’s funded pension plans are conducted as required by applicable legislation. The purpose of the actuarial valuation is to determine the funded status of the plans on a going-concern and statutory basis and to determine the required contributions. The plans are funded in accordance with applicable pension legislation and the Bank’s funding policies such that future benefit promises based on plan provisions are well secured. The assumptions used for the funding valuations are set by independent plan actuaries on the basis of the requirements of the local actuarial standards of practice and statutes. Scotiabank Pension Plan (Canada) The most significant pension plan is the Scotiabank Pension Plan (SPP) in Canada, which includes a closed defined benefit (DB) component. Employees hired in Canada on or after May 1, 2018, participate in a defined contribution (DC) component only. As the administrator of the SPP, the Bank has established a well-defined governance structure and policies to maintain compliance with legislative and regulatory requirements under OSFI and the Canada Revenue Agency. The Bank appoints a number of committees to oversee and make decisions related to the administration of the SPP. Certain committees are also responsible for the investment of the assets of the SPP Fund and for monitoring the investment managers and performance. • The Human Capital and Compensation Committee (HCOB) of the Board approves the charter of the Pension Administration and Investment Committee (PAIC), reviews reports, and approves the investment policy. The HCOB also reviews and recommends any amendments to the SPP to the Board of Directors. • PAIC is responsible for recommending the investment policy to the HCOB, for appointing and monitoring investment managers, and for reviewing auditor and actuary reports. PAIC also monitors the administration of member pension benefits. PAIC has independent member representation on the committee. • The Scotiabank Master Trust Committee (MTC) invests assets in accordance with the investment policy and all applicable legislation. The MTC assigns specific mandates to investment managers. • The Capital Accumulation Plans (CAP) Committee is responsible for the administration and investment of the DC component of the SPP including the selection and monitoring of investment options available to DC participants. Actuarial valuations for funding purposes for the SPP are conducted on an annual basis. The most recent funding valuation was conducted as of November 1, 202 1 Other benefit plans The principal other benefit plans include plans in Canada, US, Mexico, Uruguay, UK, Jamaica, Trinidad & Tobago, Colombia and other countries in the Caribbean in which the Bank operates. The most significant other benefit plans provided by the Bank are in Canada. Key assumptions The financial information reported below in respect of pension and other benefit plans is based on a number of assumptions. The most significant assumption is the discount rate used to determine the defined benefit obligation, which is set by reference to the yields on high quality corporate bonds that have durations that match the terms of the Bank’s obligations. Separate discount rates are used to determine the annual benefit expense in Canada and the US. These rates are determined with reference to the yields on high quality corporate bonds with durations that match the various components of the annual benefit expense. The discount rate used to determine the annual benefit expense for all other plans continues to be the same as the rate used to determine the defined benefit obligation. Other assumptions set by management are determined in reference to market conditions, plan-level experience, best practices and future expectations. The key weighted-average assumptions used by the Bank for the measurement of the benefit obligation and benefit expense for all of the Bank’s principal plans are summarized in the table in f) below. Risk management The Bank’s defined benefit pension plans and other benefit plans expose the Bank to a number of risks. Some of the more significant risks include interest rate risk, investment risk, longevity risk and health care cost increases, among others. These risks could result in higher defined benefit expense and a higher defined benefit obligation to the extent that: • there is a decline in discount rates; and/or • plan assets returns are less than expected; and/or • plan members live long e • health care costs are higher than assumed. In addition to the governance structure and policies in place, the Bank manages risks by regularly monitoring market developments and asset investment performance. The Bank also monitors regulatory and legislative changes along with demographic trends and revisits the investment strategy and/or plan design as warranted. a) Relative size of plan obligations and assets Pension plans Other benefit plans Canada For the year ended October 31, 2022 SPP Other International Canada International Percentage of total benefit obligations 72 % 15 % 13 % 52 % 48 % Percentage of total plan assets 74 % 11 % 15 % 0 % 100 % Percentage of total benefit expense (1) 74 % 25 % 1 % 31 % 69 % Pension plans Other benefit plans Canada For the year ended October 31, 2021 SPP Other International Canada International Percentage of total benefit obligations 72 % 15 % 13 % 56 % 44 % Percentage of total plan assets 75 % 10 % 15 % 0 % 100 % Percentage of total benefit expense (1) 78 % 21 % 1 % 31 % 69 % (1) Excludes non-routine b) Cash contributions and payments The table below shows the cash contributions and payments made by the Bank to its principal plans in 2022, and the prior year.

A key factor in managing long-term investment risk is asset mix. Investing the pension assets across different asset classes and geographic regions helps to mitigate risk and to minimize the impact of declines in any single asset class, particular region or type of investment. Investment managers – including related-party managers – are typically hired and assigned specific mandates within each asset class. Pension plan asset mix guidelines are set for the long term and are documented in each plan’s investment policy. Asset mix policy typically also reflects the nature of the plan’s benefit obligations. Legislation places certain restrictions on asset mix – for example, there are usually limits on concentration in any one investment. Other concentration and quality limits are also set forth in the investment policies. Derivatives are not a significant component of the investment strategy and cannot be used without specific authorization; currently, the main use of derivatives is for currency hedging. Asset mix guidelines are reviewed at least once each year, and adjusted, where appropriate, based on market conditions and opportunities. However, large asset class shifts are not common, and typically reflect a change in the pension plan’s situation (e.g. plan amendments) and/or in the investment strat e The tables below show the weighted-average actual and target ass e Pension plans Other benefit plans Asset category % Actual Actual Actual Actual Cash and cash equivalents 4 % 4 % – % – % Equity investments Quoted in an active market 38 % 34 % 37 % 42 % Non quoted 5 % 11 % – % – % 43 % 45 % 37 % 42 % Fixed income investments Quoted in an active market 4 % 6 % 58 % 58 % Non quoted 36 % 35 % – % – % 40 % 41 % 58 % 58 % Property Quoted in an active market – % – % 5 % – % Non quoted 1 % 1 % – % – % 1 % 1 % 5 % – % Other Quoted in an active market – % – % – % – % Non quoted 12 % 9 % – % – % 12 % 9 % – % – % Total 100 % 100 % 100 % 100 % Target asset allocation at October 31, 2022 Asset category % Pension plans Other benefit plans Cash and cash equivalents – % – % Equity investments 42 % 38 % Fixed income investments 44 % 57 % Property 1 % 5 % Other 13 % – % Total 100 % 100 %

Operating segments	29 Operating Segments Scotiabank is a diversified financial services institution that provides a wide range of financial products and services to retail, commercial and corporate customers around the world. The Bank’s businesses are grouped into four business lines: Canadian Banking, International Banking, Global Banking and Markets and Global Wealth Management. Other smaller business segments are included in the Other segment. The results of these business segments are based upon the internal financial reporting systems of the Bank. The accounting policies used in these segments are generally consistent with those followed in the preparation of the consolidated financial statements as disclosed in Note 3. Notable accounting measurement differences are: • tax normalization adjustments related to the gross-up • the grossing up of tax-exempt non-interest before-tax These differences in measurement enable comparison of net interest income and non-interest tax-exempt Scotiabank’s results, and average assets and liabilities, allocated by these operating segments, are as follows: For the year ended October 31, 2022 Taxable equivalent basis ($ millions) Canadian International Global Wealth Global Banking Other (1) Total Net interest income ( 2 $ 9,001 $ 6,900 $ 764 $ 1,630 $ (180 ) $ 18,115 Non-interest ( 3 4 3,029 2,827 4,617 3,542 (714 ) 13,301 Total revenues 12,030 9,727 5,381 5,172 (894 ) 31,416 Provision for credit losses 209 1,230 6 (66 ) 3 1,382 Depreciation and amortization 628 503 183 172 45 1,531 Non-interest 4,760 4,709 3,076 2,502 524 15,571 Income tax expense 1,670 618 551 653 (734 ) 2,758 Net income $ $ 2,667 $ 1,565 $ 1,911 $ (732 ) $ 10,174 Net income attributable to non-controlling – 249 9 – – 258 Net income attributable to equity holders of the Bank 4,763 2,418 1,556 1,911 (732 ) 9,916 Average assets ($ billions) 430 207 33 445 167 1,282 Average liabilities ($ billions) 332 152 47 414 263 1,208 (1) Includes all other smaller operating segments and corporate adjustments, such as the elimination of the tax-exempt gross-up non-interest (2) Interest income is reported net of interest expense as management relies primarily on net interest income as a performance measure.

Guarantees, Commitments and Pledged Assets	34 Guarantees, Commitments and Pledged Assets (a) Guarantees The Bank enters into various types of guarantees and indemnifications in the normal course of business. Guarantees represent an undertaking to another party to make a payment to that party when certain specified events occur. The various guarantees and indemnifications that the Bank provides with respect to its customers and other third parties are presented below: 2022 2021 As at October 31 ($ millions) Maximum potential (1) Maximum potential (1) Standby letters of credit and letters of guarantee $ 41,977 $ 37,277 Liquidity facilities 6,361 4,942 Indemnifications 926 1,306 (1) The maximum potential amount of future payments represents those guarantees that can be quantified and excludes other guarantees that cannot be quantified. As many of these guarantees will not be drawn upon and the maximum potential amount of future payments listed above does not consider the possibility of recovery under recourse or collateral provisions, the above amounts are not indicative of future cash requirements, credit risk, or the Bank’s expected losses from these arrangements. (i) Standby letters of credit and letters of guarantee Standby letters of credit and letters of guarantee are irrevocable undertakings by the Bank on behalf of a customer, to make payments to a third party in the event that the customer is unable to meet its obligations to the third party. Generally, the term of these guarantees does not exceed four years. The types and amounts of collateral security held by the Bank for these guarantees is generally the same as for loans. (ii) Liquidity facilities The Bank’s backstop liquidity facilities are committed liquidity and provided to asset-backed commercial paper conduits, administered by the Bank. These facilities generally provide an alternative source of financing in the event market disruption prevents the conduit from issuing commercial paper or, in some cases, when certain specified conditions or performance measures are not met. These facilities generally have a term of up to three years. (iii) Indemnifications In the ordinary course of business, the Bank enters into many contracts which contain indemnification provisions, such as purchase contracts, service agreements, trademark licensing agreements, director / officer contracts, escrow arrangements, sales of assets or businesses, outsourcing agreements, leasing arrangements, clearing system arrangements, securities lending agency agreements and structured transactions. The Bank cannot estimate the maximum potential future amount that may be payable. The Bank has not made any significant payments under such indemnifications. (b) Other indirect commitments In the normal course of business, various other indirect commitments are outstanding which are not reflected on the Consolidated Statement of Financial Position. These may include: • Commercial letters of credit which require the Bank to honour drafts presented by a third-party when specific activities are completed; • Commitments to extend credit which represent undertakings to make credit available in the form of loans or other financings for specific amounts and maturities, subject to specific conditions; • Securities lending transactions under which the Bank, acting as principal or agent, agrees to lend securities to a borrower. The borrower must fully collateralize the security loan at all times. The market value of the collateral is monitored relative to the amounts due under the agreements, and where necessary, additional collateral is obtained; and • Security purchase commitments which require the Bank to fund future investments. These financial instruments are subject to normal credit standards, financial controls and monitoring procedures. The table below provides a detailed breakdown of the Bank’s other indirect commitments expressed in terms of the contractual amounts of the related commitment or contract which are not reflected on the Consolidated Statement of Financial Position.

Financial Instruments - Risk Management	35 Financial Instruments – Risk Management The Bank’s principal business activities result in a balance sheet that consists primarily of financial instruments. In addition, the Bank uses derivative financial instruments for both trading and hedging purposes. The principal financial risks that arise from transacting financial instruments include credit risk, liquidity risk and market risk. The Bank’s framework to monitor, evaluate and manage these risks is consistent with that in place as at October 31, 2022: • extensive risk management policies define the Bank’s risk appetite, set the limits and controls within which the Bank and its subsidiaries can operate, and reflect the requirements of regulatory authorities. These policies are approved by the Bank’s Board of Directors, either directly or through the Risk Committee of the Board, (the Board); • guidelines are developed to clarify risk limits and conditions under which the Bank’s risk policies are implemented; • processes are implemented to identify, evaluate, document, report and control risk. Standards define the breadth and quality of information required to make a decision; and • compliance with risk policies, limits and guidelines is measured, monitored and reported to ensure consistency against defined goals. Further details on the fair value of financial instruments and how these amounts were determined are provided in Note 7. Note 10 provides details on the terms and conditions of the Bank’s derivative financial instruments including notional amounts, remaining term to maturity, credit risk, and fair values of derivatives used in trading and hedging activities. (a) Credit risk Credit risk is the risk of loss resulting from the failure of a borrower or counterparty to honour its financial or contractual obligations to the Bank. The Bank’s Credit Risk Appetite and Credit Risk Policy are developed by its Global Risk Management (GRM) department and limits are reviewed and approved by the Board on an annual and biennial basis, respectively. The Credit Risk Appetite defines target markets and risk tolerances that are developed at an all-Bank • target markets and product offerings are well defined; • the risk parameters for new underwritings and for the portfolios as a whole are clearly specified; and • transactions, including origination, syndication, loan sales and hedging, are managed in a manner to ensure the goals for the overall portfolio are met. The Credit Risk Policy sets out, among other things, the credit risk rating systems and associated parameter estimates, the delegation of authority for granting credit, and the calculation of allowance for credit losses. It forms an integral part of enterprise-wide policies and procedures that encompass governance, risk management and control structure. The Bank’s credit risk rating systems are designed to support the determination of key credit risk parameter estimates which measure credit and transaction risk. For non-retail (i) Credit risk exposures Credit risk exposures disclosed below are presented based on the Basel framework utilized by the Bank i.e. exposures subject to credit risk capital. The Bank uses the Advanced Internal Ratings Based approach (AIRB) for all material Canadian, U.S., European portfolios, and for a significant portion of all international corporate and commercial portfolios. The remaining portfolios, including other individual portfolios, are treated under the standardized approach. Under the AIRB approach, the Bank uses internal risk parameter estimates, based on historical experience and appropriate margin of conservatism, for probability of default (PD), loss given default (LGD) and exposure at default (EAD). Under the standardized approach, credit risk is estimated using the risk weights as prescribed by the Basel framework either based on credit assessments by external rating agencies or based on the counterparty type for non-retail loan-to-value As at October 31 ($ millions) 2022 2021 Exposure at default (1) Category Drawn (2) Undrawn Other (3) Total Total By counterparty type Non-retail AIRB portfolio Corporate $ 233,214 $ 123,347 $ 96,865 $ 453,426 $ 372,462 Bank 16,812 4,739 15,874 37,425 35,792 Sovereign 223,678 1,170 9,308 234,156 213,300 473,704 129,256 122,047 725,007 621,554 Standardized portfolio Corporate (4) 48,804 2,879 8,183 59,866 63,647 Bank 3,752 26 10 3,788 3,064 Sovereign 8,718 34 231 8,983 8,773 61,274 2,939 8,424 72,637 75,484 Total non-retail $ 534,978 $ 132,195 $ 130,471 $ 797,644 $ 697,038 Retail AIRB portfolio Real estate secured 232,133 22,435 – 254,568 227,927 Qualifying revolving 16,018 30,417 – 46,435 41,771 Other retail 33,696 4,214 – 37,910 36,207 $ 281,847 $ 57,066 $ – $ 338,913 $ 305,905 Standardized portfolio Real estate secured 63,054 – – 63,054 54,617 Other retail (4) 47,242 847 – 48,089 36,445 110,296 847 – 111,143 91,062 Total retail $ 392,143 $ 57,913 $ – $ 450,056 $ 396,967 Total $ 927,121 $ 190,108 $ 130,471 $ 1,247,700 $ 1,094,005 By geography ( 5 Canada $ 549,356 $ 119,722 $ 40,971 $ 710,049 $ 639,748 United States 146,109 50,517 51,046 247,672 194,424 Chile 54,234 1,326 4,968 60,528 54,777 Mexico 45,988 1,522 3,283 50,793 38,422 Peru 27,789 1,147 3,240 32,176 28,152 Colombia 11,951 384 956 13,291 14,446 Other International Europe 21,158 7,459 17,539 46,156 47,179 Caribbean 29,482 1,487 1,088 32,057 27,673 Latin America (other) 17,649 1,336 1,905 20,890 14,080 All other 23,405 5,208 5,475 34,088 35,104 Total $ 927,121 $ 190,108 $ 130,471 $ 1,247,700 $ 1,094,005 (1) Exposure at default is presented after credit risk mitigation.

(ii) Credit quality of non-retail Credit decisions are made based upon an assessment of the credit risk of the individual borrower or counterparty. Key factors considered in the assessment include: the borrower’s management; the borrower’s current and projected financial results and credit statistics; the industry in which the borrower operates; economic trends; and geopolitical risk. Banking units and Global Risk Management also review the credit quality of the credit portfolio across the organization on a regular basis to assess whether economic trends or specific events may affect the performance of the portfolio.

Non-retail (iii) Credit quality of retail exposures The Bank’s retail portfolios consist of a number of relatively small loans to a large number of borrowers. The portfolios are distributed across Canada and a wide range of countries. As such, the portfolios inherently have a high degree of diversification. In addition, as of October 31, 2022, 28% of the Canadian banking residential mortgage portfolio is insured and the average loan-to-value Retail AIRB portfolio The data in the table below provides a distribution of the retail AIRB exposure within each PD range by asset class: As at October 31 ($ millions) 2022 2021 Exposure at default (1) Real estate secured Category of (PD) grades PD range Mortgages HELOC Qualifying Other retail Total Total Exceptionally Low 0.0000% – 0.0499% $ 63,677 $ 24,644 $ 12,865 $ 853 $ 102,039 $ 91,426 Very Low 0.0500% – 0.1999% 87,387 14,544 11,085 5,358 118,374 106,994 Low 0.2000% – 0.9999% 48,158 4,522 12,018 20,145 84,843 77,215 Medium Low 1.0000% – 2.9999% 9,569 – 5,522 7,157 22,248 20,744 Medium 3.0000% – 9.9999% 729 430 4,160 3,335 8,654 7,316 High 10.0000% – 19.9999% 263 72 223 565 1,123 917 Extremely High 20.0000% – 99.9999% 328 47 452 336 1,163 863 Default 100% 143 55 110 161 469 430 Total $ 210,254 $ 44,314 $ 46,435 $ 37,910 $ 338,913 $ 305,905 (1) After credit risk mitigation. Retail standardized portfolio The retail standardized portfolio of $111 billion as at October 31, 2022 (2021 – $91 billion) was comprised of residential mortgages, personal loans, credit cards and lines of credit to individuals, mainly in the Latin American and Caribbean region. Commencing in the third quarter, small business loans of $7 billion have been included as other regulatory retail. loan-to-value (iv) Collateral Collateral held In the normal course of business, to reduce its exposure to counterparty credit risk, the Bank receives collateral for capital markets related activities. The following are examples of the terms and conditions customary to collateral for these types of transactions: • The risks and rewards of the pledged assets reside with the pledgor. • Additional collateral is required when the market value of the transaction exceeds thresholds agreed upon with the pledgor. • The Bank is normally permitted to sell or repledge the collateral it receives, although this right is specific to each agreement under which the collateral is pledged. • Upon satisfaction of the obligation, the Bank must return the pledged assets, unless the Bank has the right to sell or repledge the collateral it receives, in which case the Bank must return comparable collateral to the pledgor. As at October 31, 2022, the approximate market value of cash and securities collateral accepted that may be sold or repledged by the Bank was $259 billion (2021 – $192 billion). This collateral is held primarily in connection with reverse repurchase agreements, margin loans, securities lending and derivative transactions. The Bank also borrows securities under standard securities borrowing agreements that it is able to re-pledge. re-pledged re-pledged Collateral pledged In the normal course of business, securities and other assets are pledged to secure an obligation, participate in clearing or settlement systems, or operate in a foreign jurisdiction. Note 3 4 Assets acquired in exchange for loans The carrying value of assets acquired in exchange for loans as at October 31, 2022 was $274 million (2021 – $257 million) mainly comprised of real estate and was classified as either held for sale or held for use as appropriate. (b) Liquidity risk Liquidity risk is the risk that the Bank is unable to meet its financial obligations in a timely manner at reasonable prices. The Bank’s liquidity risk is subject to extensive risk management controls and is managed within the framework of policies and limits approved by the Board. The Board receives reports on risk exposures and performance against approved limits. The Asset-Liability Committee (ALCO) provides senior management oversight of liquidity risk. The key elements of the Bank’s liquidity risk management framework include: • liquidity risk measurement and management limits, including limits on maximum net cash outflow by currency over specified short-term horizons; • prudent diversification of its wholesale funding activities by using a number of different funding programs to access the global financial markets and manage its maturity profile, as appropriate; • large holdings of liquid assets to support its operations, which can generally be sold or pledged to meet the Bank’s obligations; • liquidity stress testing, including Bank-specific, global-systemic, and combination systemic/Bank-specific scenarios; and • liquidity contingency planning. The Bank’s foreign operations have liquidity management frameworks that are similar to the Bank’s framework. Local deposits are managed from a liquidity risk perspective based on the local management frameworks and regulatory requirements. (i) Commitments to extend credit In the normal course of business, the Bank enters into commitments to extend credit in the form of loans or other financings for specific amounts and maturities, subject to specific conditions. These commitments, which are not reflected on the Consolidated Statement of Financial Position, are subject to normal credit standards, financial controls and monitoring procedures. (ii) Derivative instruments The Bank is subject to liquidity risk relating to its use of derivatives to meet customer needs, generate revenues from trading activities, manage market and credit risks arising from its lending, funding and investment activities, and lower its cost of capital. The maturity profile of the notional amounts of the Bank’s derivative instruments is summarized in Note 10(b). (c) Market risk Market risk arises from changes in market prices and rates (including interest rates, credit spreads, equity prices, foreign exchange rates and commodity prices), the correlations between them, and their levels of volatility. Market risk is subject to extensive risk management controls, and is managed within the framework of market risk policies and limits approved by the Board. The ALCO and Market Risk Management and Policy Committee oversee the application of the framework set by the Board, and monitor the Bank’s market risk exposures and the activities that give rise to these exposures. The Bank uses a variety of metrics and models to measure and control market risk exposures. The measurements used are selected based on an assessment of the nature of risks in a particular activity. The principal measurement techniques are Value at Risk (VaR), stress testing, sensitivity analysis and simulation modeling. The Board reviews results from these metrics quarterly. Models are independently validated internally prior to implementation and are subject to formal periodic review. VaR is a statistical measure that estimates the potential loss in value of the Bank’s trading positions due to adverse market movements over a defined time horizon with a specified confidence level. The quality of the Bank’s VaR is validated by regular back testing analysis, in which the VaR is compared to theoretical and actual profit and loss results. To complement VaR, the Bank also uses stress testing to examine the impact that abnormally large swings in market factors and periods of prolonged inactivity might have on trading portfolios. The stress testing program is designed to identify key risks and ensure that the Bank’s capital can absorb potential losses from abnormal events. The Bank subjects its trading portfolios to a series of stress tests on a daily, weekly and monthly basis. In trading portfolios, sensitivity analysis is used to measure the effect of changes in risk factors, including prices and volatility, on financial products and portfolios. In non-trading (i) Non-trading Interest rate risk is the risk of loss due to the following: changes in the level, slope and curvature of the yield curve; the volatility of interest rates and changes in customer preferences (e.g. mortgage prepayment rates). The Bank actively manages its interest rate exposures with the objective of protecting and enhancing net interest income within established risk tolerances. Interest rate risk arising from the Bank’s funding and investment activities is managed in accordance with Board-approved policies and global limits, which are designed to control the risk to net interest income and economic value of equity. The income limit measures the effect of a specified shift in interest rates on the Bank’s annual net interest income over the next twelve months, while the economic value limit measures the impact of a specified change in interest rates on the present value of the Bank’s net assets. These calculations are based on models that consider a number of inputs and are on a constant balance sheet and make no assumptions for management actions that may mitigate the risk. Interest rate sensitivity Based on the Bank’s interest rate positions, the following table shows the pro-forma pre-tax As at October 31 ($ millions) 2022 2021 (1) Net interest income Economic value of equity Canadian Other Total Canadian Other Total Net interest Economic value 100 bp increase $ (118 ) $ (222 ) $ (340 ) $ (800 ) $ (1,221 ) $ (2,021 ) 100 bp increase $ 212 $ (1,173 ) 100 bp decrease $ 127 $ 199 $ 326 $ 606 $ 1,053 $ 1,659 25 bp decrease $ (64 ) $ 209 (1) Prior period amounts have been restated to conform with current period presentation. (ii) Non-trading Foreign currency risk is the risk of loss due to changes in spot and forward rates, and the volatility of currency exchange rates. Non-trading The Bank is subject to foreign currency risk on the earnings of its foreign operations. To manage this risk, foreign currency revenues and expenses, which are primarily denominated in U.S. dollars, are projected over a number of future fiscal quarters. The ALCO assesses economic data and forecasts to decide on the portion of the estimated future foreign currency revenues and expenses to hedge. Hedging instruments normally include foreign currency spot and forward contracts, as well as foreign currency options and swaps. As at October 31, 2022, a one percent increase (decrease) in the Canadian dollar against all currencies in which the Bank operates decreases (increases) the Bank’s before-tax million) in the absence of hedging activity, due primarily from exposure to U.S. dollars. A similar change in the Canadian dollar as at October 31, 2022 would increase (decrease) the unrealized foreign currency translation losses in the accumulated other comprehensive income in equity by approximate (iii) Non-trading Equity risk is the risk of loss due to adverse movements in equity prices. Equity price risk is often classified into two categories: general equity risk, which refers to the sensitivity of an instrument or portfolio’s value to changes in the overall level of equity prices, and specific equity risk, which refers to that portion of an individual equity instrument’s price volatility that is determined by entity-specific characteristics. The Bank is exposed to equity risk through its equity investment portfolios, which are controlled by Board-approved portfolio and VaR limits. Equity investments include common and preferred shares, as well as a diversified portfolio of third-party managed funds. The majority of the Bank’s equity investment portfolios are managed by Group Treasury under the strategic direction of the ALCO. Group Treasury delegates the management of a portion of equity and equity-related portfolios to other external fund managers to take advantage of these fund managers’ expertise in particular market niches and products. The fair value of equity securities designated at FVOCI is shown in Note 12. (iv) Trading portfolio risk management The Bank’s policies, processes and controls for trading activities are designed to achieve a balance between pursuing profitable trading opportunities and managing earnings volatility within a framework of sound and prudent practices. Trading activities are primarily customer focused. Market risk arising from the Bank’s trading activities is managed in accordance with Board-approved policies and limits, including aggregate VaR and stress testing limits.

(d) Operational risk Operational risk is the risk of loss resulting from people, inadequate or failed processes and systems, or from external events. Operational risk includes third party risk management and legal risk but excludes strategic risk and reputational risk. It also exists in some form in each of the Bank’s business and support activities, and third parties to whom activities have been outsourced. It can result in financial loss, regulatory sanctions and damage to the Bank’s reputation. The Bank’s Operational Risk Management Framework outlines the Bank’s structured approach for effective management of enterprise-wide operational risk in a manner consistent with best practices and regulatory requirements.

Basis of consolidation	Basis of consolidation The consolidated financial statements include the assets, liabilities, financial performance and cash flows of the Bank and all of its subsidiaries, after elimination of intercompany transactions and balances. Subsidiaries are defined as entities controlled by the Bank. The Bank’s subsidiaries can be classified as entities controlled through voting interests or structured entities. The Bank consolidates a subsidiary from the date it obtains control. For the Bank to control an entity, all three elements of control should be in existence: • power over the investee; • exposure, or rights, to variable returns from involvement with the investee; and • the ability to use power over the investee to affect the amount of the Bank’s returns. The Bank does not control an investee when it is acting as an agent. The Bank assesses whether it is an agent by determining whether it is primarily engaged to act on behalf of and for the benefit of another party or parties. The Bank reassesses whether it controls an investee if facts and circumstances indicate that one or more of the elements of control has changed. Voting-interest subsidiaries Control is presumed with an ownership interest of more than 50% of the voting rights in an entity unless there are other factors that indicate that the Bank does not control the entity despite having more than 50% of voting rights. The Bank may consolidate an entity when it owns less than 50% of the voting rights when it has one or more other attributes of power: • by virtue of an agreement, over more than half of the voting rights; • to govern the financial and operating policies of the entity under a statute or an agreement; • to appoint or remove the majority of the members of the board of directors or equivalent governing body and control of the entity is by that board or body; or • to govern the financial and operating policies of the entity through the size of its holding of voting rights relative to the size and dispersion of holding of the other vote holders and voting patterns at shareholder meetings (i.e., de facto control). Non-controlling non-controlling non-controlling Structured entities Structured entities are designed to accomplish certain well-defined objectives and for which voting or similar rights are not the dominant factor in deciding who controls the entity. The Bank controls an entity when it is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. The Bank consolidates all structured entities that it controls. Investments in associates An associate is an entity in which the Bank has significant influence, but not control, over the operating and financial policies of the entity. Investments in associates are recognized initially at cost, which includes the purchase price and other costs directly attributable to the purchase. Associates are accounted for using the equity method which reflects the Bank’s share of the increase or decrease of the post-acquisition earnings and other movements in the associate’s equity. Investments in associates are evaluated for impairment at the end of each financial reporting period, or more frequently if events or changes in circumstances indicate the existence of objective evidence of impairment. For purposes of applying the equity method for an investment that has a different reporting period from the Bank, adjustments are made for the effects of any significant events or transactions that occur between the reporting date of the investment and the reporting date of the Bank. Joint arrangements The Bank’s investments in joint arrangements over which the Bank has joint control are classified as either joint operations or joint ventures depending on the contractual rights and obligations of each investor, rather than the legal structure of the joint arrangement. Similar to accounting for investment in associates, for joint ventures, investments are recognized initially at cost and accounted for using the equity method which reflects the Bank’s share of the increase or decrease of the post-acquisition earnings and other movements in the joint venture’s equity. Investments in joint ventures are evaluated for impairment at the end of each financial reporting period, or more frequently if events or changes in circumstances indicate the existence of objective evidence of impairment. For joint operations, the Bank recognizes its direct rights to, and its share of jointly held assets, liabilities, revenues and expenses. These have been incorporated in the consolidated financial statements under the appropriate headings.
Translation of foreign currencies	Translation of foreign currencies The financial statements of each of the Bank’s foreign operations are measured using its functional currency, being the currency of the primary economic environment of the foreign operation. Translation gains and losses related to the Bank’s monetary items are recognized in non-interest non-monetary non-monetary non-monetary non-monetary Unrealized gains and losses arising upon translation of foreign operations, together with any gains or losses arising from hedges of those net investment positions to the extent effective, are credited or charged to net change in unrealized foreign currency translation gains/losses in other comprehensive income in the Consolidated Statement of Comprehensive Income. On disposal or meeting the definition of partial disposal of a foreign operation, an appropriate portion of the translation differences previously recognized in other comprehensive income are recognized in the Consolidated Statement of Income.
Financial assets and liabilities	Financial assets and liabilities Recognition and initial measurement The Bank, on the date of origination or purchase, recognizes loans, debt and equity securities, deposits and subordinated debentures at the fair value of the consideration paid or received. Regular-way The initial measurement of a financial asset or liability is at fair value plus transaction costs that are directly attributable to its purchase or issuance. For instruments measured at fair value through profit or loss, transaction costs are recognized immediately in profit or loss. Classification and measurement, derecognition, and impairment of financial instruments Classification and measurement Classification and measurement of financial assets Financial assets include both debt and equity instruments, are classified into one of the following measurement categories: • Amortized cost; • Fair value through other comprehensive income (FVOCI); • Fair value through profit or loss (FVTPL); • Elected at fair value through other comprehensive income (Equities only); or • Designated at FVTPL Debt instruments Debt instruments, including loans and debt securities, are classified into one of the following measurement categories: • Amortized cost; • Fair value through other comprehensive income (FVOCI); • Fair value through profit or loss (FVTPL); or • Designated at FVTPL Classification of debt instruments is determined based on: (i) The business model under which the asset is held; and (ii) The contractual cash flow characteristics of the instrument. Business model assessment A business model assessment involves determining how financial assets are managed to generate cash flows. The Bank’s business model assessment is based on the following categories: • Held to collect: The objective of this business model is to hold assets and collect contractual cash flows. Any sales of the asset are incidental to the objective of the model. • Held to collect and for sale: Both collecting contractual cash flows and sales are integral to achieving the objectives of the business model. • Other business model: The business model is neither held-to-collect held-to-collect The Bank assesses the business model at a portfolio level reflective of how groups of assets are managed together to achieve a particular business objective. For the assessment of a business model, the Bank takes into consideration the following factors: • How the performance of assets in a portfolio is evaluated and reported to group heads and other key decision makers within the Bank’s business lines; • How compensation is determined for the Bank’s business lines’ management that manages the assets; • How the business lines’ management is compensated for managing the Bank’s assets based on the fair value or the contractual cash flows collected; • Whether the assets are held for trading purposes; • The risks that affect the performance of assets held within a business model and how those risks are managed; and • The frequency and volume of sales in prior periods and expectations about future sales activity. Contractual cash flow characteristics assessment The contractual cash flow characteristics assessment involves assessing the contractual features of an instrument to determine if they give rise to cash flows that are consistent with a basic lending arrangement. Contractual cash flows are consistent with a basic lending arrangement if they represent cash flows that are solely payments of principal and interest on the principal amount outstanding (SPPI). Principal is defined as the fair value of the instrument at initial recognition. Principal may change over the life of the instrument due to repayments or amortization of premium/discount. Interest is defined as the consideration for the time value of money and the credit risk associated with the principal amount outstanding and for other basic lending risks and costs (liquidity risk and administrative costs), and a profit margin. If the Bank identifies any contractual features that could significantly modify the cash flows of the instrument such that they are no longer consistent with a basic lending arrangement, the related financial asset is classified and measured at FVTPL. Debt instruments measured at amortized cost Debt instruments are measured at amortized cost if they are held within a business model whose objective is to hold for collection of contractual cash flows where those cash flows represent solely payments of principal and interest. After initial measurement, debt instruments in this category are carried at amortized cost. Interest income on these instruments is recognized in interest income using the effective interest rate method. The effective interest rate is the rate that discounts estimated future cash payments or receipts through the expected life of the financial asset to the gross carrying amount of a financial asset. Amortized cost is calculated by taking into account any discount or premium on the acquisition, transaction costs and fees that are an integral part of the effective interest rate. Impairment on debt instruments measured at amortized cost is calculated using the expected credit loss approach. Loans and debt securities measured at amortized cost are presented net of the allowance for credit losses (ACL) in the Statement of Financial Position. Debt instruments measured at FVOCI Debt instruments are measured at FVOCI if they are held within a business model whose objective is to hold for collection of contractual cash flows and for selling financial assets, where the assets’ cash flows represent payments that are solely payments of principal and interest. Subsequent to initial recognition, unrealized gains and losses on debt instruments measured at FVOCI are recorded in other comprehensive income (OCI), unless the instrument is designated in a fair value hedge relationship. When designated in a fair value hedge relationship, any changes in fair value due to changes in the hedged risk are recognized in Non-interest Non-interest Impairment on debt instruments measured at FVOCI is determined using the expected credit loss approach. The ACL on debt instruments measured at FVOCI does not reduce the carrying amount of the asset in the Consolidated Statement of Financial Position, which remains at its fair value. Instead, an amount equal to the allowance that would arise if the assets were measured at amortized cost is recognized in OCI with a corresponding charge to provision for credit losses in the Consolidated Statement of Income. The accumulated allowance recognized in OCI is recycled to the Consolidated Statement of Income upon derecognition of the debt instrument. Debt instruments measured at FVTPL Debt instruments are measured at FVTPL if assets: (i) are held for trading purposes; (ii) are held as part of a portfolio managed on a fair value basis; or (iii) whose cash flows do not represent payments that are solely payments of principal and interest. These instruments are measured at fair value in the Consolidated Statement of Financial Position, with transaction costs recognized immediately in the Consolidated Statement of Income as part of Non-interest Non-interest Debt instruments designated at FVTPL The Bank designates certain debt instruments at FVTPL upon initial recognition, and the designation is irrevocable. The FVTPL designation is available when a fair value is reliably estimated, and doing so eliminates or significantly reduces an accounting mismatch which would otherwise arise. Debt instruments designated at FVTPL are recorded in the Consolidated Statement of Financial Position at fair value. Changes in fair value are recognized in Non-interest Equity instruments Equity instruments are classified into one of the following measurement categories: • Fair value through profit or loss (FVTPL); or • Elected at fair value through other comprehensive income (FVOCI). Equity instruments measured at FVTPL Equity instruments are measured at FVTPL, unless an election is made to designate them at FVOCI upon purchase, with transaction costs recognized immediately in the Consolidated Statement of Income as part of Non-interest Equity instruments measured at FVOCI At initial recognition, the Bank has an option to classify non-trading instrument-by-instrument Gains and losses on these instruments, including when derecognized/sold, are recorded in OCI and are not subsequently reclassified to the Consolidated Statement of Income. As such, there is no specific impairment requirement. Dividends received are recorded in Interest income in the Consolidated Statement of Income. Any transaction costs incurred upon purchase of the security are added to the cost basis of the security and are not reclassified to the Consolidated Statement of Income on sale of the security. Classification and measurement of financial liabilities Financial liabilities are classified into one of the following measurement categories: • Fair value through profit or loss (FVTPL); • Amortized cost; or • Designated at FVTPL. Financial liabilities measured at FVTPL Financial liabilities measured at FVTPL are held principally for the purpose of repurchasing in the near term, or form part of a portfolio of identified financial instruments that are managed together and for which there is evidence of a recent actual pattern of short term profit-taking. Financial liabilities are recognized on a trade date basis and accounted for at fair value, with changes in fair value and any gains or losses recognized in the Consolidated Statement of Income as part of the non-interest Financial liabilities measured at amortized cost Deposits, subordinated notes and debentures are accounted for at amortized cost. Interest on deposits, calculated using the effective interest rate method, is recognized as interest expense. Interest on subordinated notes and debentures, including capitalized transaction costs, is recognized using the effective interest rate method as interest expense. Financial liabilities designated at FVTPL The Bank designates certain financial liabilities at FVTPL upon initial recognition, and the designation is irrevocable. The FVTPL designation is available when a fair value is reliably estimated. Financial liabilities are designated at FVTPL when it meets one of the following criteria: • The designation eliminates or significantly reduces an accounting mismatch which would otherwise arise; or • A group of financial liabilities are managed and their performance is evaluated on a fair value basis, in line with a documented risk management strategy; or • The financial liability contains one or more embedded derivatives which significantly modify the cash flows otherwise required. Financial liabilities designated at FVTPL are recorded in the Consolidated Statement of Financial Position at fair value. Any changes in fair value are recognized in Non-interest Determination of fair value The fair value of a financial asset or liability is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the principal, or in its absence, the most advantageous market to which the Bank has access at the measurement date. The Bank values instruments carried at fair value using quoted market prices, where available. Fair value based on unadjusted quoted market prices for identical instruments in active markets represents a Level 1 valuation. When quoted market prices are not available, the Bank maximizes the use of observable inputs within valuation models. When a fair value is based on all significant market observable inputs, the valuation is classified as Level 2. Valuations that require the significant use of unobservable inputs are considered Level 3. Inception gains and losses are only recognized where the valuation is dependent on observable market data; otherwise, they are deferred and amortized over the life of the related contract or until the valuation inputs become observable. IFRS 13, Fair Value Measurement In determining fair value for certain instruments or portfolios of instruments, valuation adjustments or reserves may be required to arrive at a more accurate representation of fair value. These adjustments include those made for credit risk, bid-offer
Derecognition of financial assets and liabilities	Derecognition of financial assets and liabilities Derecognition of financial assets A financial asset is derecognized when the contractual rights to the cash flows from the asset has expired; or the Bank transfers the contractual rights to receive the cash flows from the financial asset; or has assumed an obligation to pay those cash flows to an independent third-party; or the Bank has transferred substantially all the risks and rewards of ownership of that asset to an independent third-party. Management determines whether substantially all the risk and rewards of ownership have been transferred by quantitatively comparing the variability in cash flows before and after the transfer. If the variability in cash flows remains significantly similar subsequent to the transfer, the Bank has retained substantially all of the risks and rewards of ownership. Where substantially all the risks and rewards of ownership of the financial asset are neither retained nor transferred, the Bank derecognizes the transferred asset only if it has lost control over that asset. Control over the asset is represented by the practical ability to sell the transferred asset. If the Bank retains control over the asset, it will continue to recognize the asset to the extent of its continuing involvement. At times such continuing involvement may be in the form of investment in senior or subordinated tranches of notes issued by non-consolidated On derecognition of a financial asset, the difference between the carrying amount and the sum of (i) the consideration received (including any new asset obtained less any new liability assumed) and (ii) any cumulative gain or loss that had been recognized in other comprehensive income is recognized in the Consolidated Statement of Income. Transfers of financial assets that do not qualify for derecognition are reported as secured financings in the Consolidated Statement of Financial Position. The derecognition criteria are applied to the transfer of part of an asset, rather than the asset as a whole, only if such part comprises specifically identified cash flows from the asset, a fully proportionate share of the cash flows from the asset, or a fully proportionate share of specifically identified cash flows from the asset. Derecognition of financial liabilities A financial liability is derecognized when the obligation under the liability is discharged, canceled or expires. If an existing financial liability is replaced by another from the same counterparty on substantially different terms, or the terms of the existing liability are substantially modified, such an exchange or modification is treated as a derecognition of the original liability and the recognition of a new liability at fair value. The difference in the respective carrying amount of the existing liability and the new liability is recognized as a gain/loss in the Consolidated Statement of Income. Impairment Scope The Bank applies a three-stage approach to measure allowance for credit losses, using an expected credit loss approach as required under IFRS 9, for the following categories of financial instruments that are not measured at fair value through profit or loss: • Amortized cost financial assets; • Debt securities classified as at FVOCI; • Off-balance • Financial guarantee contracts. Expected credit loss impairment model The Bank’s allowance for credit losses calculations are outputs of models with a number of underlying assumptions regarding the choice of variable inputs and their interdependencies. The expected credit loss impairment model reflects the present value of all cash shortfalls related to default events either (i) over the following twelve months or (ii) over the expected life of a financial instrument depending on credit deterioration from inception. The allowance for credit losses reflects an unbiased, probability-weighted outcome which considers multiple scenarios based on reasonable and supportable forecasts. This impairment model measures credit loss allowances using a three-stage approach based on the extent of credit deterioration since origination: • Stage 1 – Where there has not been a significant increase in credit risk (SIR) since initial recognition of a financial instrument, an amount equal to 12 months expected credit loss is recorded. The expected credit loss is computed using a probability of default occurring over the next 12 months. For those instruments with a remaining maturity of less than 12 months, a probability of default corresponding to remaining term to maturity is used. • Stage 2 – When a financial instrument experiences a SIR subsequent to origination but is not considered to be in default, it is included in Stage 2. This requires the computation of expected credit loss based on the probability of default over the remaining estimated life of the financial instrument. • Stage 3 – Financial instruments that are considered to be in default are included in this stage. Similar to Stage 2, the allowance for credit losses captures the lifetime expected credit losses. Measurement of expected credit loss The probability of default (PD), exposure at default (EAD), and loss given default (LGD) inputs used to estimate expected credit losses are modelled based on macroeconomic variables that are most closely related with credit losses in the relevant portfolio. Details of these statistical parameters/inputs are as follows: • PD – The probability of default is an estimate of the likelihood of default over a given time horizon. A default may only happen at a certain time over the remaining estimated life if the facility has not been previously derecognized and is still in the portfolio. • EAD – The exposure at default is an estimate of the exposure at a future default date, considering expected changes in the exposure after the reporting date, including repayments of principal and interest, whether scheduled by contract or otherwise, expected drawdowns on committed facilities, and accrued interest from missed payments. • LGD – The loss given default is an estimate of the loss arising in the case where a default occurs at a given time. It is based on the difference between the contractual cash flows due and those that the lender would expect to receive, including from the realization of any collateral. It is usually expressed as a percentage of the EAD. Forward-looking information The estimation of expected credit losses for each stage and the assessment of significant increases in credit risk consider information about past events and current conditions as well as reasonable and supportable forecasts of future events and economic conditions. The estimation and application of forward-looking information may require significant judgment. Macroeconomic factors In its models, the Bank relies on a broad range of forward-looking economic information as inputs, such as: GDP growth, unemployment rates, central bank interest rates, and house-price indices. The inputs and models used for calculating expected credit losses may not always capture all characteristics of the market at the date of the financial statements. Qualitative adjustments or overlays may be made as temporary adjustments using expert credit judgment. Multiple forward-looking scenarios The Bank determines its allowance for credit losses using four probability-weighted forward-looking scenarios. The Bank considers both internal and external sources of information and data in order to achieve unbiased projections and forecasts. The Bank prepares the scenarios using forecasts generated by Scotiabank Economics (SE). The forecasts are created using internal and external models which are modified by SE as necessary to formulate a ‘base case’ view of the most probable future direction of relevant economic variables as well as a representative range of other possible forecast scenarios. The process involves the development of three additional economic scenarios and consideration of the relative probabilities of each outcome. The ‘base case’ represents the most likely outcome and is aligned with information used by the Bank for other purposes such as strategic planning and budgeting. The other scenarios represent more optimistic and more pessimistic outcomes. The Bank has identified and documented key drivers of credit risk and credit losses for each portfolio of financial instruments and, using an analysis of historical data, has estimated relationships between macroeconomic variables, credit risk, and credit losses. Assessment of significant increase in credit risk (SIR) At each reporting date, the Bank assesses whether there has been a significant increase in credit risk for exposures since initial recognition by comparing the risk of default occurring over the remaining expected life from the reporting date and the date of initial recognition. The assessment considers borrower-specific quantitative and qualitative information without consideration of collateral, and the impact of forward-looking macroeconomic factors. The common assessments for SIR on retail and non-retail Retail portfolio – For retail exposures, a significant increase in credit risk cannot be assessed using forward looking information at an individual account level. Therefore, the assessment must be done at the segment level. Segment migration thresholds exist for each PD model by product which considers the proportionate change in PD as well as the absolute change in PD. The thresholds used for PD migration are reviewed and assessed at least annually unless there is a significant change in credit risk management practices in which case the review is brought forward. Non-retail non-retail non-retail non-borrower Expected life When measuring expected credit loss, the Bank considers the maximum contractual period over which the Bank is exposed to credit risk. All contractual terms are considered when determining the expected life, including prepayment, and extension and rollover options. For certain revolving credit facilities, such as credit cards, the expected life is estimated based on the period over which the Bank is exposed to credit risk and how the credit losses are mitigated by management actions. Presentation of allowance for credit losses in the Statement of Financial Position • Financial assets measured at amortized cost: as a deduction from the gross carrying amount of the financial assets; • Debt instruments measured at fair value through other comprehensive income: no allowance is recognized in the Statement of Financial Position because the carrying value of these assets is their fair value. However, the allowance determined is presented in the accumulated other comprehensive income; • Off-balance Modified financial assets If the terms of a financial asset are modified or an existing financial asset is replaced with a new one, an assessment is made to determine if the existing financial asset should be derecognized. Where a modification does not result in derecognition, the date of origination continues to be used to determine SIR. Where a modification results in derecognition, the new financial asset is recognized at its fair value on the modification date. The modification date is also the date of origination for this new asset. The Bank may modify the contractual terms of loans for either commercial or credit reasons. The terms of a loan in good standing may be modified for commercial reasons to provide competitive pricing to borrowers. Loans are also modified for credit reasons where the contractual terms are modified to grant a concession to a borrower that may be experiencing financial difficulty. For all financial assets modifications of the contractual terms may result in derecognition of the original asset when the changes to the terms of the loans are considered substantial. These terms include interest rate, authorized amount, term, or type of underlying collateral. The original loan is derecognized, and the new loan is recognized at its fair value. The difference between the carrying value of the derecognized asset and the fair value of the new asset is recognized in the Consolidated Statement of Income. For all loans, performing and credit-impaired, where the modification of terms did not result in the derecognition of the loan, the gross carrying amount of the modified loan is recalculated based on the present value of the modified cash flows discounted at the original effective interest rate and any gain or loss from the modification is recorded in the provision for credit losses line in the Consolidated Statement of Income. Definition of default The Bank considers a financial instrument to be in default as a result of one or more loss events that occurred after the date of initial recognition of the instrument and the loss event has a negative impact on the estimated future cash flows of the instrument that can be reliably estimated. This includes events that indicate: • significant financial difficulty of the borrower; • default or delinquency in interest or principal payments; • high probability of the borrower entering a phase of bankruptcy or a financial reorganization; • measurable decrease in the estimated future cash flows from the loan or the underlying assets that back the loan. The Bank considers that default has occurred and classifies the financial asset as impaired when it is more than 90 days past due, except for credit card receivables that are treated as defaulted when 180 days past due, unless reasonable and supportable information demonstrates that a more lagging default criterion is appropriate. Write-off The Bank writes off an impaired financial asset (and the related impairment allowance), either partially or in full, when there is no realistic prospect of recovery. Where financial assets are secured, write-off write-off written-off. Purchased loans All purchased loans are initially measured at fair value on the date of acquisition. As a result, no allowance for credit losses would be recorded in the Consolidated Statement of Financial Position on the date of acquisition. Purchased loans may fit into either of the two categories: Performing loans or Purchased Credit - Purchased performing loans follow the same accounting as originated performing loans and are reflected in Stage 1 on the date of the acquisition. They will be subject to a 12-month PCI loans are reflected in Stage 3 and are always subject to lifetime allowance for credit losses. Any changes in the expected cash flows since the date of acquisition are recorded as a charge/recovery in the provision for credit losses in the Consolidated Statement of Income at the end of all reporting periods subsequent to the date of acquisition. Modification of financial instruments in the context of interest rate benchmark reform – Phase 2 amendments When the basis for determining the contractual cash flows of a financial asset or financial liability measured at amortized cost is changed as a result of interest rate benchmark reform (IBOR reform), the Bank updates the effective interest rate of the financial asset or financial liability similar to a floating rate financial instrument and does not derecognize or adjust the carrying amount (the practical expedient). The practical expedient is applied only when the modification is required as a direct consequence of IBOR reform, and the new basis for determining the contractual cash flows is economically equivalent to the previous basis. If changes are made to a financial asset or financial liability in addition to changes to the basis for determining the contractual cash flows required by the interest rate benchmark reform, then the Bank sequentially updates the effective interest first to reflect the change required by IBOR reform and then applies its policies on modification or derecognition of Offsetting of financial instruments Financial assets and financial liabilities with the same counterparty are offset, with the net amount reported in the Consolidated Statement of Financial Position, only if there is a legally enforceable right to offset the recognized amounts and there is an intention to settle on a net basis, or to realize the assets and settle the liabilities simultaneously. When financial assets and financial liabilities are offset in the Consolidated Statement of Financial Position, the related income and expense items will also be offset in the Consolidated Statement of Income, unless specifically prohibited by an applicable accounting standard. Cash and deposits with financial institutions Cash and deposits with financial institutions comprise cash, cash equivalents, demand deposits with banks and other financial institutions, and highly liquid investments that are readily convertible to cash, subject to an insignificant risk of changes in value. These investments are those with less than three months maturity from the date of acquisition. Precious metals Precious metals are carried at fair value less costs to sell, and any changes in value are credited or charged to non-interest Securities purchased and sold under resale agreements Securities purchased under resale agreements (reverse repurchase agreements) require the purchase of securities by the Bank from a counterparty with an agreement entered to resell the securities at a fixed price at a future date. Since the Bank is reselling the securities at a fixed price at a future date, the risks and rewards have not been transferred to the Bank. The Bank has the right to liquidate the securities purchased in the event of counterparty default. Whereas securities sold under agreements to repurchase (repurchase agreements) require the sale of securities by the Bank to a counterparty with an agreement entered simultaneously to purchase the securities back at a fixed price at a future date. Since the Bank is purchasing the securities back at a fixed price at a future date, the risks and rewards have not been transferred from the Bank. The counterparty has the right to use the collateral pledged by the Bank in the event of default. These agreements are treated as collateralized financing arrangements and are initially recognized at amortized cost. The party disbursing the cash takes possession of the securities serving as collateral for the financing and having a market value equal to, or more than, the principal amount loaned. The securities received under reverse repurchase agreements and securities delivered under repurchase agreements are not recognized on, or derecognized from, the Consolidated Statement of Financial Position, unless the risks and rewards of ownership are obtained or relinquished. The related interest income and interest expense are recorded on an accrual basis using the effective interest rate in the Consolidated Statement of Income. Obligations related to securities sold short Obligations related to securities sold short arise in dealing and market-making activities where debt securities and equity shares are sold without possessing such securities. Similarly, if securities purchased under an agreement to resell are subsequently sold to third parties, the obligation to return the securities is recorded as a short sale within obligations related to securities sold short in the Consolidated Statement of Financial Position. These trading liabilities are measured at fair value with any gains or losses included in non-interest Securities lending and borrowing Securities lending and borrowing transactions are usually collateralized by securities or cash. The transfer of the securities to counterparties is only reflected on the Consolidated Statement of Financial Position if the risks and rewards of ownership are also transferred. For cash collateral advanced or received, the Bank presents these transactions as securities sold under a repurchase agreement or securities purchased under a reverse repurchase agreement, respectively. Interest income on cash collateral paid and interest expense on cash collateral received together with securities lending income and securities borrowing fee are reported in the Consolidated Statement of Income. Securities borrowed are not recognized on the Consolidated Statement of Financial Position unless they are then sold to third parties, in which case the obligation to return the securities is recorded as a trading liability and measured at fair value with any gains or losses included in non-interest Derivative instruments Derivative instruments are contracts whose value is derived from interest rates, foreign exchange rates, commodity prices, equity prices or other financial variables. Most derivative instruments can be characterized as interest rate contracts, foreign exchange and gold contracts, commodity contracts, equity contracts or credit contracts. Derivative instruments are either exchange-traded contracts or negotiated over-the-counter over-the-counter The Bank enters into these derivative contracts for trading purposes, as well as to manage its risk exposures (i.e., to manage the Bank’s non-trading Derivatives embedded in other financial liabilities or host contracts are treated as separate stand-alone derivatives when the following conditions are met: • their economic characteristics and risks are not closely related to those of the host contract; • a separate instrument with the same terms as the embedded derivative would meet the definition of a derivative; and • the combined contract is not held for trading or designated at fair value through profit or loss. Where an embedded derivative is separable from the host contract but the fair value, as at the acquisition or reporting date, cannot be reliably measured separately, the entire combined contract is measured at fair value. All embedded derivatives are presented on the Consolidated Statement of Financial Position on a combined basis with the host contracts. Changes in fair value of embedded derivatives that are separated from the host contract are recognized in non-interest All derivatives, including embedded derivatives that must be separately accounted for, are recorded at fair value in the Consolidated Statement of Financial Position. The determination of the fair value of derivatives includes consideration of credit risk, estimated funding costs and ongoing direct costs over the life of the instruments. Inception gains or losses on derivatives are only recognized where the valuation is dependent on observable market data, otherwise, they are deferred and amortized over the life of the related contract, or until the valuation inputs become observable. The gains and losses resulting from changes in fair values of trading derivatives are included in non-interest Changes in the fair value of non-trading non-interest non-interest Changes in the fair value of derivatives that qualify for hedge accounting are recorded as non-interest
Hedge accounting	Hedge accounting The Bank has elected to continue to apply the hedge accounting requirements of IAS 39. Also, the Bank has implemented the additional hedge accounting disclosures that are required by the IFRS 9 related amendments to IFRS 7 Financial Instruments: Disclosures The Bank formally documents all hedging relationships and its risk management objective and strategy for undertaking these hedge transactions at inception. The hedge documentation includes identification of the asset, liability, firm commitment or highly probable forecasted transaction being hedged, the nature of the risk being hedged, the hedging instrument used, and the method used to assess the effectiveness of the hedge. The Bank also formally assesses, both at each hedge’s inception and on an ongoing basis, whether the hedging instruments are highly effective in offsetting changes in fair value or cash flows of the hedged items within an 80-125% 80-125% Hedge ineffectiveness is measured and recorded in non-interest 24-month There are three types of hedges: (i) fair value hedges, (ii) cash flow hedges and (iii) net investment hedges. Fair value hedges For fair value hedges, the change in fair value of the hedging instrument is offset in the Consolidated Statement of Income by the change in fair value of the hedged item attributable to the hedged risk. For hedges that are discontinued, the hedged item is no longer adjusted for changes in fair value. The cumulative fair value adjustment of the hedged item is amortized to interest income over its remaining term to maturity or written off to non-interest Cash flow hedges For cash flow hedges, the change in fair value of the hedging instrument, to the extent effective, is recorded in other comprehensive income until the corresponding gains and losses on the hedged item are recognized in income. For hedges that are discontinued, the cumulative unrealized gain or loss recognized in other comprehensive income is reclassified to interest income and/or salaries and employee benefits as the variability in the cash flows of hedged item affects income. However, if the hedged item is derecognized or the forecasted transaction is no longer expected to occur, the unrealized gain or loss is reclassified immediately to non-interest For the Bank’s cash flow hedges of forecasted transactions that are directly affected by the IBOR Reform, it is assumed that the benchmark interest rate will not be altered as a result of the IBOR Reform for purposes of assessing whether the transactions are highly probable or whether the transactions are still expected to occur. Net investment hedges For net investment hedges, the change in fair value of the hedging instrument, to the extent effective, is recorded in other comprehensive income until the corresponding cumulative translation adjustments on the hedged net investment are recognized in income. The Bank designates foreign currency liabilities and foreign currency forwards as hedging instruments to manage the foreign currency exposure and impact on capital ratios arising from foreign operations.
Property and equipment	Property and equipment Land is carried at cost. Buildings (including building fittings), equipment, and leasehold improvements are carried at cost less accumulated depreciation and accumulated impairment losses, if any. Cost includes expenditures that are directly attributable to the acquisition of the asset. Depreciation is calculated using the straight-line method over the estimated useful life of the related asset less any residual value as follows: buildings – up to 40 years, building fittings – up to 15 years, equipment 3 to 10 years, and leasehold improvements – lease term determined by the Bank. Depreciation expense is included in the Consolidated Statement of Income under non-interest year-end When major components of building and equipment have different useful lives, they are accounted for separately and depreciated over each component’s estimated useful life. Net gains and losses on disposal are included in non-interest
Assets held-for-sale	Assets held-for-sale Non-current non-financial as held-for-sale held-for-sale Non-current non-financial held-for-sale non-interest non-interest Non-financial held-for-sale held-for-use. held-for-sale, held-for-use,
Business combinations and goodwill	Business combinations and goodwill The Bank follows the acquisition method of accounting for the acquisition of a business. The Bank considers the date on which control is obtained and it legally transfers the consideration for the acquired assets and assumed liabilities of the subsidiary to be the date of acquisition. The cost of an acquisition is measured at the fair value of the consideration paid. The fair value of the consideration transferred by the Bank in a business combination is calculated as the sum of the acquisition date fair value of the assets transferred by the Bank, the liabilities incurred by the Bank to former owners of the acquiree, and the equity interests, including any options, issued by the Bank. The Bank recognizes the acquisition date fair values of any previously held investment in the subsidiary and contingent consideration as part of the consideration transferred in exchange for the acquisition. A gain or loss on any previously held investments of an acquiree is recognized in non-interest In general, all identifiable assets acquired (including intangible assets) and liabilities assumed (including any contingent liabilities) are measured at the acquisition date fair value. The Bank records identifiable intangible assets irrespective of whether the assets have been recognized by the acquiree before the business combination. Non-controlling non-controlling non-controlling Any excess of the cost of acquisition over the Bank’s share of the net fair value of the identifiable assets acquired and liabilities assumed is recorded as goodwill. If the cost of acquisition is less than the fair value of the Bank’s share of the identifiable assets acquired and liabilities assumed, the resulting gain is recognized immediately in non-interest During the measurement period (which is within one year from the acquisition date), the Bank may, on a retrospective basis, adjust the amounts recognized at the acquisition date to reflect new information obtained about facts and circumstances that existed as of the acquisition date. The Bank accounts for acquisition-related costs as expenses in the periods in which the costs are incurred and the services are received. Subsequent to acquisition, the Bank accounts for the following assets and liabilities recognized in a business combination as described below: • Contingent liabilities, until resolved, are measured at the higher of the amount that would be recognized as a provision or the amount initially recognized, with any change recognized in the Consolidated Statement of Income. • Indemnification assets are measured on the same basis as the item to which the indemnification relates. • Contingent consideration classified as a liability is measured at fair value, with any change recognized in the Consolidated Statement of Income. • Liabilities to non-controlling After initial recognition of goodwill in a business combination, goodwill in aggregate is measured at cost less any accumulated impairment losses. Goodwill is not amortized but tested for impairment annually and when circumstances indicate that the carrying value may be impaired. Goodwill is reviewed at each reporting date to determine whether there is any indication of impairment. For the purpose of impairment testing, goodwill acquired in a business combination is, on the acquisition date, allocated to each of the Bank’s group of cash-generating units (CGUs) that is expected to benefit from the combination. CGUs to which goodwill has been allocated are aggregated so that the level at which impairment is tested reflects the lowest level at which goodwill is monitored for internal management purposes. The Bank determines the carrying value of the CGU using a regulatory capital approach based on credit, market, operational risks and leverage, consistent with the Bank’s capital attribution for business line performance measurement. The recoverable amount is the greater of fair value less costs of disposal and value in use. If either fair value less costs of disposal or value in use exceeds the carrying amount, there is no need to determine the other. The recoverable amount of the CGU has been determined using the fair value less costs of disposal method. The estimation of fair value less costs of disposal involves significant judgment in the determination of inputs. In determining fair value less costs of disposal, an appropriate valuation model is used which considers various factors including normalized net income, control premiums and price earnings multiples. These calculations are corroborated by valuation multiples and quoted share prices for publicly traded subsidiaries or other available fair value indicators. An impairment loss is recognized if the carrying amount of the CGU exceeds the recoverable amount. An impairment loss, in respect of goodwill, is not reversed.
Intangible assets	Intangible assets Intangible assets represent identifiable non-monetary The cost of a separately acquired intangible asset includes its purchase price and directly attributable costs of preparing the asset for its intended use. Intangibles acquired as part of a business combination are initially recognized at fair value. In respect of internally generated intangible assets, initial measurement includes all directly attributable costs necessary to create, produce, and prepare the asset to be capable of operating in the manner intended by management. After initial recognition, an intangible asset is carried at its cost less any accumulated amortization and accumulated impairment losses. Intangible assets that have finite useful lives are initially measured at cost and are amortized on a straight-line basis over their useful lives as follows: computer software – 5 to 10 years; and other intangible assets – 5 to 20 years. Amortization expense is included in the Consolidated Statement of Income under operating expenses – depreciation and amortization. As intangible assets are non-financial non-financial
Impairment of non-financial assets	Impairment of non-financial The carrying amount of the Bank’s non-financial non-financial If any indication of impairment exists, then the asset’s recoverable amount is estimated. The recoverable amount of an asset or CGU is the greater of its value in use and its fair value less costs of disposal. The Bank’s corporate assets do not generate separate cash inflows. If there is an indication that a corporate asset may be impaired, then the recoverable amount is determined for the CGU to which the corporate asset belongs. An impairment loss is recognized if the carrying amount of an asset or a CGU exceeds its recoverable amount. Impairment losses of continuing operations are recognized in the Consolidated Statement of Income in those expense categories consistent with the nature of the impaired asset. Impairment losses recognized in prior periods are reassessed at each reporting date for any indication that the loss had decreased or no longer exists. An impairment loss is reversed if there has been a change in the estimates used to determine the recoverable amount. An impairment loss is reversed only to the extent that the asset’s carrying amount does not exceed the carrying amount that would have been determined, net of depreciation or amortization, if no impairment loss had been recognized. Such reversal is recognized in the Consolidated Statement of Income. Significant judgment is applied in determining the non-financial
Corporate income taxes	Corporate income taxes The Bank follows the balance sheet liability method for corporate income taxes. Under this method, deferred tax assets and liabilities represent the cumulative amount of tax applicable to temporary differences which are the differences between the carrying amount of the assets and liabilities, and their values for tax purposes. Deferred tax assets are recognized only to the extent it is probable that sufficient taxable profits will be available against which the benefit of these deferred tax assets can be utilized. Deferred tax assets and liabilities are measured using enacted or substantively enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Deferred and current tax assets and liabilities are only offset when they arise in the same tax reporting group and where the Bank has both the legal right and the intention to settle on a net basis or to realize the asset and settle the liability simultaneously. The Bank maintains provisions for uncertain tax positions that it believes appropriately reflect the risk of tax positions under discussion, audit, dispute, or appeal with tax authorities, or which are otherwise considered to involve uncertainty. These provisions are made using the Bank’s best estimate of the amount expected to be paid based on an assessment of all relevant factors, which are reviewed at the end of each reporting period. It is possible that additional liability and income tax expense could arise in the future, depending on the acceptance of the Bank’s tax positions by the relevant tax authorities in the jurisdictions in which the Bank operates. Income tax is recognized in the Consolidated Statement of Income except where it relates to items recognized in other comprehensive income or directly in equity, in which case income tax is recognized in the same line as the related item.
Leases	Leases At inception of a contract, the Bank assesses whether a contract is, or contains, a lease. A contract is a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. When the Bank is a lessee it recognizes a right-of-use Asset A ROU is an asset that represents a lessee’s right to use an underlying asset for the lease term. The ROU asset is initially measured at cost, which is based on the initial amount of the lease liability, and any direct costs incurred, any lease payments made at or before the commencement date net of lease incentives received and estimated decommissioning costs. The ROU asset is subsequently measured at cost less accumulated depreciation and accumulated impairment losses, if any. The ROU asset is depreciated using the straight-line method from the commencement date to the earlier of the end of the useful life of the ROU asset or the end of the lease term. The depreciation is recorded in Depreciation and amortization in the Consolidated Statement of Income. In addition, the ROU asset is adjusted for certain remeasurements of the lease liability. Liability At commencement date, the Bank initially measures the lease liability at the present value of the future lease payments, discounted using the Bank’s incremental borrowing rate that takes into account the Bank’s credit risk and economic environment in which the lease is entered. The lease liability is subsequently measured at amortized cost using the effective interest method. It is re-measured When the lease liability is re-measured right-of-use Presentation The Bank presents ROU assets in Property and equipment and lease liabilities in Other liabilities in the Consolidated Statement of Financial Position. Determining lease term The Bank’s expectation of exercising the option to renew a lease is determined by assessing if the Bank is “reasonably certain” to exercise that option. The Bank will be reasonably certain to exercise an option when factors create a significant economic incentive to do so. This assessment considers the following criteria: key locations for its branch network, locations on which the Bank has spent significant capital on renovation work, contribution to profit, value of locations based on current economic environment and the remaining term of existing leases.
Provisions	Provisions A provision, including for restructuring, is recognized if, as a result of a past event, the Bank has a present legal or constructive obligation that can be estimated reliably, and it is probable that an outflow of economic benefits will be required to settle the obligation. The amount recognized as a provision is the Bank’s best estimate of the consideration required to settle the present obligation, taking into account the risks and uncertainties surrounding the obligation. If the effect of the time value of money is considered material, provisions are determined by discounting the expected future cash flows at a pre-tax
Insurance contracts	Insurance contracts Gross premiums for life insurance contracts are recognized as income when due. Gross premiums for non-life Gross insurance claims for life insurance contracts reflect the cost of all claims arising during the year. Gross insurance claims for property and casualty insurance contracts include paid claims and movements in outstanding claim liabilities. Insurance premiums ceded to reinsurers are accounted as an expense in the same period as the premiums for the direct insurance contracts to which they relate.
Guarantees	Guarantees A guarantee is a contract that contingently requires the Bank to make specified payments to reimburse the holder for a loss it incurs because a specified debtor failed to make payment when due in accordance with the original or modified terms of a debt instrument. Guarantees include standby letters of credit, letters of guarantee, indemnifications, credit enhancements and other similar contracts. Guarantees that qualify as a derivative are accounted for in accordance with the policy for derivative instruments. For guarantees that do not qualify as a derivative, a liability is recorded for the fair value of the obligation assumed at inception. The fair value of the obligation at inception is generally based on the discounted cash flow of the premium to be received for the guarantee, resulting in a corresponding asset. Subsequent to initial recognition, such guarantees are measured at the higher of the initial amount, less amortization to recognize any fee income earned over the period, and the best estimate of the amount required to settle any financial obligation arising as a result of the guarantee. Any increase in the liability is reported in the Consolidated Statement of Income.
Employee benefits	Employee benefits The Bank provides pension and other benefit plans for eligible employees in Canada and internationally. Pension benefits are offered in the form of defined benefit pension plans (generally based on an employee’s length of service and earnings), and in the form of defined contribution pension plans (where the Bank’s contribution is fixed and there is no legal or constructive obligation to pay further amounts). Other benefits provided include post-retirement health care, dental care and life insurance, along with other long-term employee benefits such as long-term disability benefits. Defined benefit pension plans and other post-retirement benefit plans The cost of these employee benefits is actuarially determined each year using the projected unit credit method. The calculation uses management’s best estimate of a number of assumptions – including the discount rate, future compensation, health care costs, mortality, as well as the retirement age of employees. The most significant assumption is the discount rate used to determine the defined benefit obligation, which is set by reference to the yields on high quality corporate bonds that have durations that match the terms of the Bank’s obligations. Separate discount rates are used to determine the annual benefit expense in Canada and the U.S. These rates are determined with reference to the yields on high quality corporate bonds with durations that match the various components of the annual benefit expense. The discount rate used to determine the annual benefit expense for all other plans is the same as the rate used to determine the defined benefit obligation. The Bank’s net asset or liability in respect of employee benefit plans is calculated separately for each plan as the difference between the present value of future benefits earned in respect of service for prior periods and the fair value of plan assets. The net asset or liability is included in other assets and other liabilities, as appropriate, in the Consolidated Statement of Financial Position. When the net amount in the Consolidated Statement of Financial Position is an asset, the recognized asset is limited to the present value of any economic benefits available in the form of refunds from the plan or reductions in future contributions to the plan. The current service cost, net interest expense (income), past service cost (credit), settlement gain (loss) and administrative expense are recognized in net income. Net interest expense (income) is calculated by applying the discount rate to the net defined benefit asset or liability. When the benefits of a plan are improved (reduced), a past service cost (credit) is recognized immediately in net income. Remeasurements comprising of actuarial gains and losses, the effect of the asset ceiling and the return on plan assets in excess of or less than the interest income on the fair value of assets are recognized immediately in the Consolidated Statement of Financial Position with a charge or credit to the Statement of Other Comprehensive Income (OCI) in the period in which they occur. Amounts recorded in OCI are not recycled to the Consolidated Statement of Income. Other long-term employee benefits Other long-term employee benefits are accounted for similarly to defined benefit pension plans and other post-retirement benefit plans described above, except that remeasurements are recognized in the Consolidated Statement of Income in the period in which they arise. Defined contribution plans The costs of such plans are equal to contributions payable by the Bank to employees’ accounts for service rendered during the period and expensed. Short-term employee benefits Short-term employee benefits are expensed as the related service is provided and a liability is measured on an undiscounted basis net of payments made.
Recognition of income and expenses	Interest and similar income and expenses For all non-trading contractual terms of the financial instrument (for example, prepayment options) and includes any fees or incremental costs that are directly attributable to the instrument and are an integral part of the effective interest rate, but not future credit losses. For trading financial instruments, mark-to-market non-interest The carrying amount of interest-bearing financial instruments, measured at amortized cost or classified as FVOCI, is adjusted if the Bank revises its estimates of payments or receipts. The adjusted carrying amount is calculated based on the original effective interest rate and the change in carrying amount is recorded as non-interest Once the carrying value of a financial asset or a group of similar financial assets has been reduced due to an impairment loss, interest income continues to be recognized based on net effective interest rate inherent in the investment. Loan origination costs are deferred and amortized into interest income using the effective interest method over the expected term of the loan. Loan fees are recognized in interest income over the appropriate lending or commitment period. Mortgage prepayment fees are recognized in interest income when received, unless they relate to a minor modification to the terms of the mortgage, in which case the fees are deferred and amortized using the effective interest method over the remaining period of the original mortgage. Loan syndication fees are deferred and amortized in interest income over the term of the loan where the yield the Bank retains is less than that of the comparable lenders in the syndicate. Loan commitment fees for loans that are likely to be drawn down and other credit related fees are deferred (together with any incremental costs) and recognized as part of the interest income on the loan. When it is unlikely that a loan will be drawn down, the loan commitment fees are recognized in non-interest Fee and commission revenues Revenue is recognized once the Bank’s customer has obtained control of the service. The transfer of control occurs when the Bank’s customer has the ability to direct the use of and obtain the benefits of the banking services and the contractual performance obligation to the customer has been satisfied. The Bank records revenue gross of expenses where it is the principal in performing a service to the customer and net of expenses where the Bank is an agent for these services. The assessment of principal or agent requires judgement on the basis of whether the Bank controls the services before they are transferred to the customer. From time to time, the Bank may receive variable consideration such as performance fees. These fees are only recognized when it is highly probable that the Bank will not need to reverse a significant amount of revenue. Card revenues include interchange fees, annual fees and other card related fees. Interchange fees are calculated as a percentage of the transaction and are recognized on the transaction date. Annual fees are recognized in income over 12 months. Other card fees are transaction-based and are recognized on the transaction date. The Bank operates various loyalty points programs, which allow customers to accumulate points when using the Bank’s products and services. Loyalty point liabilities are subject to periodic remeasurement to reflect the expected cost of redemption. Where the customer has the option to redeem points for statement credits, the cost of the loyalty program is presented net of card fees. Where points can only be redeemed for goods or services, interchange revenue allocated to the loyalty rewards is recognized when the rewards are redeemed. Reward costs are recorded in non-interest Banking services fees consist of fees earned on personal, business and government deposit activities. Personal deposit-related fees consist of account maintenance and various transaction-based services. Business and government deposit-related fees consist of commercial deposit and treasury management services and other cash management services. These fees are recognized on the transaction date or over time as services are provided to the customer. Credit fees include fees earned for providing letters of credit and guarantee, loan commitments, bankers’ acceptances, and for arranging loan syndications. These fees are recognized on the transaction date or over time as services are provided based on contractual agreements with the customer. Mutual funds fees include management and administration fees which are earned in the Bank’s wealth management business. These fees are calculated as a percentage of the fund’s net asset value and recognized as the service is provided. From time to time, the Bank may also recognize performance fees from some funds. These fees are only recognized to the extent that it is highly probable that a significant reversal of revenue will not occur. Brokerage fees relate to fees earned for providing full-service and discount brokerage services to clients. These fees are contractually agreed and can be asset-based or linked to individual transactions. Such fees are recognized as the service is provided to clients or on the trade date. Investment management and trust fees include administration, trust services and other investment services provided to clients. These fees are contractually agreed upon and can be linked to portfolio values or individual transactions. Such fees are recognized as the service is provided to clients to the extent that it is highly probable that a significant reversal of revenue will not occur. Underwriting and other advisory fees relate to fees earned for services provided to clients in relation to the placement of debt and equities. Such fees also include services to clients for mergers, acquisitions, financial restructurings and other corporate finance activities. These fees are recognized when the service has been performed and/or contractual milestones are completed. Performance and completion fees are variable consideration and generally contingent on the successful completion of a transaction. Other fees and commissions include commissions earned on the sale of third party insurance products to the Bank’s customers. Such fees and commissions are recognized when the performance obligation is completed. Fee and commission expenses Fee and commission expenses relate to transaction and service fees which are expensed as the services are received. Dividend income Dividend income on equity securities is recognized when the Bank’s right to receive payment is established, which is on the ex-dividend Share-based payments Share-based payments awarded to employees are recognized as compensation expense in the Consolidated Statement of Income over the vesting period based on the number of awards expected to vest including the impact of expected forfeitures. For awards that are delivered in tranches, each tranche is considered a separate award and accounted for separately. Stock appreciation rights and other awards that must be settled for cash are classified as liabilities. Liability-classified awards are re-measured re-measurement Plain vanilla options and other awards that must be settled for shares are classified as equity awards. Equity-classified awards are expensed based on the grant date fair value with a corresponding increase to equity – other reserves in the Consolidated Statement of Financial Position. If an option is exercised, both the exercise price proceeds together with the amount recorded in other reserves is credited to equity – common shares in the Consolidated Statement of Financial Position. For stock appreciation rights and plain vanilla options, the Bank estimates fair value using an option pricing model. The option pricing model requires inputs such as the exercise price of the option, the current share price, the risk free interest rate, expected dividends, expected volatility (calculated using an equal weighting of implied and historical volatility) and specific employee exercise behaviour patterns based on statistical data. For other awards, fair value is the quoted market price of the Bank’s common shares at the reporting date. Where derivatives are used to economically hedge share-based payment expense, related mark-to-market non-interest
Dividends on shares	Dividends on shares Dividends on common and preferred shares and other equity instruments are recognized as a liability and deducted from equity when they are declared and no longer at the discretion of the Bank.
Segment reporting	Segment reporting Management’s internal view is the basis for the determination of operating segments. The operating segments are those whose operating results are regularly reviewed by the Bank’s chief operating decision-maker to make decisions about resources to be allocated to the segment and assess its performance. The Bank has four operating segments: Canadian Banking, International Banking, Global Wealth Management and Global Banking and Markets. The Other category represents smaller operating segments, including Group Treasury and other corporate items, which are not allocated to an operating segment. These segments offer different products and services and are managed separately based on the Bank’s management and internal reporting structure. The results of these business segments are based upon the internal financial reporting systems of the Bank. The accounting policies used in these segments are generally consistent with those followed in the preparation of the consolidated financial statements by the Bank. The only notable accounting measurement difference is the grossing up of revenues which are tax-exempt before-tax tax-exempt Given the complexity of the Bank, various estimates and allocation methodologies are used in the preparation of the business segment financial information. The funding value of assets and liabilities is transfer-priced at wholesale market rates, and corporate expenses are allocated to each segment on an equitable basis using various parameters. As well, capital is apportioned to the business segments on a risk-based methodology. Transactions between segments are recorded within segment results as if conducted with a third-party and are eliminated on consolidation.
Earnings per share (EPS)	Earnings per share (EPS) Basic EPS is computed by dividing net income for the period attributable to the Bank’s common shareholders by the weighted-average number of common shares outstanding during the period. Diluted EPS is calculated by dividing adjusted net income for the period attributable to common shareholders by the weighted-average number of diluted common shares outstanding for the period. In the calculation of diluted earnings per share, earnings are adjusted for changes in income or expenses that would result from the issuance of dilutive shares. The weighted-average number of diluted common shares outstanding for the period reflects the potential dilution that would occur if options, securities or other contracts that entitle their holders to obtain common shares had been outstanding from the beginning of the period (or a later date) to the end of the period (or an earlier date). Instruments determined to have an antidilutive impact for the period are excluded from the calculation of diluted EPS. The number of additional shares for inclusion in diluted EPS for share-based payment options is determined using the treasury share method. Under this method, the net number of incremental common shares is determined by assuming that in-the-money The number of additional shares associated with capital instruments that potentially result in the issuance of common shares is based on the terms of the contract. On occurrence of contingencies as specified in the Non-Viability

[1]These amounts represent the gains and losses from fair value changes of Level 3 instruments still held at the end of the period that are recorded in the Consolidated Statement of Income.[2]Gains or losses for items in Level 3 may be offset with losses or gains on related hedges in Level 1 or Level 2.[3]Certain unrealized gains and losses on derivative assets and liabilities are largely offset by mark-to-market changes on other instruments included in trading revenues in the Consolidated Statement of Income, since these instruments act as an economic hedge to certain derivative assets and liabilities.[4]Certain unrealized losses on interest rate derivative contracts are largely offset by mark-to-market changes on embedded derivatives on certain deposit liabilities in the Consolidated Statement of Income.

[1]The valuation of private equity securities utilizes net asset values as reported by fund managers. Net asset values are not considered observable as the Bank cannot redeem these instruments at such values. The range for net asset values per unit or price per share has not been disclosed for these instruments since the valuations are not model-based.[2]The range of estimates represents the actual lowest and highest level inputs used to fair value financial instruments within each financial statement category.

[1]The carrying value of subordinated debentures may differ from par value due to the impact of fair value hedges used for managing interest rate risk and subordinated debentures held for market-making purposes.[2]In accordance with the provisions of the Capital Adequacy Guideline of the Superintendent, all redemptions are subject to regulatory approval and subject to the terms in the relevant prospectus.[3]These debentures contain non-viability contingent capital (NVCC) provisions. Under such NVCC provisions, outstanding debentures are convertible into a variable number of common shares if OSFI announces that the Bank has ceased, or is about to cease, to be viable, or if a federal or provincial government in Canada publicly announces that the Bank has accepted or agreed to accept a capital injection, or equivalent support, from the federal government or any provincial government or political subdivision or agent thereof without which the Bank would have been determined by OSFI to be non-viable. If such a conversion were to occur, the debentures would be converted into common shares pursuant to an automatic conversion formula defined as 150% of the par value plus accrued and unpaid interest divided by the conversion price. The conversion price is based on the greater of: (i) a floor price of $5.00 or, where applicable, the US dollar equivalent of $5.00 (subject to, in each case, adjustments in certain events as set out in the respective prospectus supplements), and (ii) the current market price of the Bank’s common shares at the time of the trigger event (10-day weighted average), where applicable converted from CAD to USD.[4]During the year, the Bank purchased for cancellation approximately US$19 million subordinated debentures due 2085.
