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 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, 2018 have been approved by the Board of Directors for issue on November 27, 2018. 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 • Available-for-sale • Equity instruments designated at fair value through other comprehensive income (effective November 1, 2017) • Debt instruments measured at fair value through other comprehensive income (effective November 1, 2017) 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 and in any future years affected. 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, other comprehensive income and income and expenses during the reporting period. Estimates made by management are based on historical experience and other 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 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 38 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	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, with the exception of the adoption of IFRS 9 (refer Note 4). 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 and exclude associates and joint arrangements. 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. The Bank controls an investee 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. For the Bank to control an entity, all of the 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. Non-controlling non-controlling 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). 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 may become involved with structured entities either at the formation stage or at a later date. The Bank controls an investee 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. Significant influence is ordinarily presumed to exist when the Bank holds between 20% and 50% of the voting rights. The Bank may also be able to exercise significant influence through board representation. The effects of potential voting rights that are currently exercisable or convertible are considered in assessing whether the Bank has significant influence. 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. If there is a loss of significant influence and the investment ceases to be an associate, equity accounting is discontinued from the date of loss of significant influence. If the retained interest on the date of loss of significant influence is a financial asset, it is measured at fair value and the difference between the fair value and the carrying value is recorded as an unrealized gain or loss in the Consolidated Statement of Income. 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 A joint arrangement is an arrangement over which two or more parties have joint control. Joint control exists only when decisions about the relevant activities (i.e., those that significantly affect the returns of the arrangement) require the unanimous consent of the parties sharing the control of the arrangement. Investments in joint arrangements 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. If there is a loss of joint control and it does not result in the Bank having significant influence over the joint venture, equity accounting is discontinued from the date of loss of joint control. If the retained interest in the former joint venture on the date of loss of joint control is a financial asset, it is measured at fair value and the difference between the fair value and the carrying value is recorded as an unrealized gain or loss in the Consolidated Statement of Income. 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 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 consideration paid. 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 effective November 1, 2017 Classification and measurement Classification and measurement of financial assets Financial assets 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 Financial assets include both debt and equity instruments. 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 Business model assessment involves determining how financial assets are managed in order to generate cash flows. The Bank’s business model assessment is based on the following categories: • Held to collect: The objective of the 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 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; • Whether the assets are held for trading purposes i.e., assets that the Bank acquires or incurs principally for the purpose of selling or repurchasing in the near term, or holds as part of a portfolio that is managed together for short-term profit or position taking; • 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 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 calculated 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 amortised cost is recognised in OCI with a corresponding charge to Provision for credit losses in the Consolidated Statement of Income. The accumulated allowance recognised 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 Financial assets classified in this category are those that have been designated by the Bank upon initial recognition, and once designated, the designation is irrevocable. The FVTPL designation is available only for those financial assets for which a reliable estimate of fair value can be obtained. Financial assets are designated at FVTPL if doing so eliminates or significantly reduces an accounting mismatch which would otherwise arise. Financial assets 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 Non-interest Equity instruments measured at FVOCI At initial recognition, there is an irrevocable option for the Bank 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 are 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 Financial liabilities classified in this category are those that have been designated by the Bank upon initial recognition, and once designated, the designation is irrevocable. The FVTPL designation is available only for those financial liabilities for which a reliable estimate of fair value can be obtained. Financial liabilities are designated at FVTPL when one of the following criteria is met: • 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 accordance 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 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. Unadjusted quoted market prices for identical instruments represent a Level 1 valuation. When quoted market prices are not available, the Bank maximizes the use of observable inputs within valuation models. When all significant inputs are observable, 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 only 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 permits a measurement exception that allows an entity to determine the fair value of a group of financial assets and liabilities with offsetting risks based on the sale or transfer of its net exposure to a particular risk (or risks). The Bank has adopted this exception through an accounting policy choice. Consequently, the fair values of certain portfolios of financial instruments are determined based on the net exposure of those instruments to particular market, credit or funding risk. 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 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. 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. 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, taking into account 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. To reflect this, 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 three probability-weighted forward-looking scenarios. The Bank considers both internal and external sources of information and data in order to achieve an 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 two 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

Transition to IFRS 9	4 Transition to IFRS 9 (a) Reconciliation of IAS 39 to IFRS 9 The following table provides the impact from the transition to IFRS 9 on the Consolidated Statement of Financial Position at transition date, November 1, 2017. The impact consists of reclassification and remeasurement. Reclassification: These adjustments reflect the movement of balances between categories on the Consolidated Statement of Financial Position with no impact to shareholders’ equity.

Future Accounting Developments	5 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 measurement impact of the adoption of new standards issued by the IASB will have on its consolidated financial statements and also evaluating the alternative elections available on transition. Effective November 1, 2018 Revenue from contracts with customers The IASB issued IFRS 15 Revenue from Contracts with Customers Revenue The standard is a control-based model as compared to the existing revenue standard which is primarily focused on risks and rewards and provides a single principle based framework to be applied to all contracts with customers that are in scope of the standard. Under the new standard, revenue is recognized when a customer obtains control of a good or service. Transfer of control occurs when the customer has the ability to direct the use of and obtain the benefits of the good or service. The standard introduces a new five step model governing revenue recognition to be applied to contracts with customers. The Bank must also determine whether its performance obligation is to provide the service itself (i.e. the Bank acts as a principal) or to arrange another party to provide the service (i.e. the Bank acts as an agent). The Bank has assessed the scope of the new guidance to be limited to fees and commission revenues from wealth management and banking services in Canadian and International Banking and underwriting and advisory fees in Global Banking and Markets. The Bank will adopt the standard and its amendments as of November 1, 2018 using the modified retrospective approach. Under this approach, the Bank will recognize the cumulative effect of initially applying the standard as an adjustment to the opening balance of retained earnings as of November 1, 2018, without restating comparative periods. As of November 1, 2018, the opening balance of retained earnings is expected to decrease by approximately $60 million (net of tax). The decrease in retained earnings relates to certain costs no longer eligible for deferral under the new standard and the re-measurement The presentation of certain costs will also change prospectively from non-interest expenses to non-interest income where amounts are deemed to be part of consideration payable to customers or the Bank is deemed to be acting as an agent. This presentation change will not have a material impact on the Bank’s consolidated financial statements. Effective November 1, 2019 Financial instruments: Prepayment features with negative compensation On October 12, 2017, the IASB issued an amendment to IFRS 9 Financial Instruments pre-payable so-called Leases On January 13, 2016, the IASB issued IFRS 16 Leases IFRS 16 is effective for the Bank on November 1, 2019. On transition, there are practical expedients available whereby the Bank will not need to reassess whether a contract is, or contains a lease, or reassess the accounting of sale leaseback transactions recognized prior to the date of initial application. A lessee will apply IFRS 16 to its leases either retrospectively to each prior reporting period presented; or retrospectively with the cumulative effect of initially applying IFRS 16 being recognized at the date of initial application. The Bank is currently in the process of assessing existing contractual relationships to identify the existing population of leases that would be recorded on the balance sheet under the new standard. The Bank continues to evaluate the potential impact to the existing IT systems and processes and next steps include performing an initial quantification of the existing obligations and reviewing the additional disclosures required by the new standard. During 2019, the Bank will also complete its assessment of various practical expedients and formulate its accounting policies under IFRS 16. IFRIC 23 Uncertainty over income tax treatments On June 7, 2017, the IASB issued IFRIC 23 that is effective for the Bank beginning November 1, 2019. The interpretation clarifies the accounting for uncertainties over income taxes. The interpretation clarifies application of recognition and measurement requirements in IAS 12 income taxes when there is uncertainty over income tax treatments. The Bank is currently assessing the impact of the interpretation. Employee Benefits On February 7, 2018, the IASB issued narrow-scope amendments to pension accounting that is effective for the Bank beginning November 1, 2019. The amendments relate to when a plan amendment, curtailment or settlement has occurred. In such instances, the Bank is required to use updated assumptions to determine current service cost and net interest for the remainder of the reporting period after the change to the plan. For the Bank, the narrow scope amendments are to be applied prospectively to plan amendments, curtailments and settlements occurring after November 1, 2019. Effective November 1, 2020 Conceptual Framework On March 29, 2018, the IASB issued the revised Conceptual Framework for Financial Reporting (Framework) that is effective for the Bank beginning November 1, 2020. The Framework itself is not a standard, and does not override existing standards. It is used by the IASB in developing accounting standards. The Bank is currently assessing the impact of the revisions. Definition of business On October 22, 2018, the IASB issued a narrow-scope amendment to IFRS 3 Business Combination. The amendments will help companies determine whether an acquisition is of a business or a group of assets. Distinguishing between a business and a group of assets is important because an acquirer recognizes goodwill only when acquiring a business. The amendments apply to transactions for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after January 1, 2020. Earlier adoption is permitted. The Bank is currently assessing the impact. Definition of material On October 31, 2018, the IASB issued amendments to IAS 1 Presentation of Financial Statements and IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors, clarifying the definition of material. Under the new definition, information is material if omitting, misstating or obscuring it could reasonably be expected to influence the decisions that the primary users of general purpose financial statements make on the basis of those financial statements, which provide financial information about a specific reporting entity. The explanations accompanying the definition have also been improved. The amendments are effective prospectively for annual periods beginning on or after January 1, 2020. Earlier adoption is permitted. The Bank is currently assessing the impact. Effective November 1, 2021 Insurance Contracts On May 18, 2017, the IASB issued IFRS 17 Insurance Contracts, which provides a comprehensive principle-based framework for the measurement and presentation of all insurance contracts. The new standard will replace IFRS 4 Insurance Contracts and requires insurance contracts to be measured using current fulfillment cash flows and for revenue to be recognized as the service is provided over the coverage period. On November 14, 2018, the IASB tentatively decided to defer the effective date, by one year, to annual periods on or after January 1, 2022. The Bank will continue to track the IASB Board’s meeting agenda items on issues and discussions related to the standard, further updates will be provided in Q1 2019. The IFRS 17 project structure and governance has been established along with a Project Management Office to assist the Executive Steering and Project Operations Committees. The committees comprise of representatives from Global Finance, Global Insurance Actuarial Services, Information Technology and the Insurance Business Operations. The Bank is currently in the Evaluation and Design Solution phase of the project, with Implementation planned for Fiscal 2019 through 2022.

Fair Value of Financial Instrum

Fair Value of Financial Instruments	12 Months Ended

Text block1 [abstract]
Fair Value of Financial Instruments	7 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 best evidence of fair value for a financial instrument is the quoted price in an active market. Unadjusted quoted market prices for identical instruments represent 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 from 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, dealers and consensus pricing services. The valuation policies relating to the IPV process require that all pricing or rate sources used be external to the Bank. On a periodic basis, an independent assessment of pricing or rate sources is performed to determine 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, greater management judgment is required for valuation purposes. 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 175. 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 as they relate to precious metals (primarily gold and silver) are valued using a discounted cash flow model incorporating market-observable inputs, including precious metals spot and forward prices and interest rate curves (Level 2). Other trading loans that serve as hedges to loan-based credit total return swaps are valued using consensus prices from Bank approved independent pricing services (Level 2). 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 (Level 1). Where quoted prices are not available, the fair value is determined by utilizing recent transaction prices, broker quotes, or pricing services (Level 2). For securities that are not actively traded, the Bank uses a discounted cash flow method, using the effective yield of a similar instrument adjusted for instrument-specific risk factors such as credit spread and contracted features (Level 2). 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 (Level 1). Where prices are not available consistently, the last available data is used and verified with a yield-based valuation approach (Level 2). In some instances, interpolated yields of similar bonds are used to price securities (Level 2). The Bank uses pricing models with observable inputs from market sources such as credit spread, interest rate curves, and recovery rates (Level 2). 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 market inputs used to price such instruments (Level 3). Mortgage-backed securities The fair value of residential mortgage-backed securities is primarily determined using third-party broker quotes and independent market data providers, where the market is more active (Level 2). Where the market is inactive, an internal price-based model is used (Level 3). Equity securities The fair value of equity securities is based on unadjusted quoted prices in active markets, where available (Level 1). Where equity securities are less frequently traded, the most recent exchange-quoted pricing is used to determine fair value. Where there is a wide bid-offer Where quoted prices in active markets are not readily available, such as for private equity securities, the fair value is determined as a multiple of the underlying earnings or percentage of underlying assets obtained from third-party general partner statements (Level 3). Income funds The fair value of income funds is based on observable unadjusted quoted prices where available (Level 1). Where quoted or active market prices are unavailable, the last available Net Asset Value, fund statements and other financial information available from third-party fund managers at the fund level are used in arriving at the fair value. Derivatives Fair values of exchange-traded derivatives are based on unadjusted quoted market prices (Level 1). 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 and forward rates and interest rate curves (Level 2). Derivative products valued using a valuation technique with significant unobservable inputs are long dated contracts (interest rate swaps, currency swaps, forward foreign exchange contracts, option contracts and certain credit default swaps) and other derivative products that reference a basket of assets, commodities or currencies. These models incorporate certain significant non-observable Loans The estimated fair value of loans carried at amortized cost reflects changes in the general level of interest rates and credit worthiness 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 (Level 3). • 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 (Level 3). • 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 (Level 3). • 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 (Level 2). Deposits under the Canada Mortgage Bond (CMB) program are fair valued by discounting expected future contractual cash flows using market observable inputs (Level 2). 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 (Level 2). For structured notes containing embedded features that are bifurcated from the Plain Vanilla notes, the fair value of the embedded derivatives is determined using option pricing models with inputs similar to other interest rate or equity derivative contracts (Level 2). The fair value of certain embedded derivatives is determined using net asset values (Level 3). 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 (Level 2). The fair values of other liabilities is determined by the discounted contractual cash flow method with appropriate currency swap curves for the remaining term (Level 2). 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. The fair values disclosed do not include non-financial 2018 2017 As at October 31 ($ millions) Total Total Total Total Assets: Cash and deposits with financial institutions $ 62,269 $ 62,269 $ 59,663 $ 59,663 Trading assets 100,262 100,262 98,464 98,464 Financial instruments designated at fair value through profit or loss 12 12 13 13 Securities purchased under resale agreements and securities borrowed 104,018 104,018 95,319 95,319 Derivative financial instruments 37,558 37,558 35,364 35,364 Investment securities – other 57,653 57,653 50,504 50,504 Investment securities – amortized cost 20,316 20,743 18,716 18,765 Loans 553,758 551,834 507,276 504,369 Customers’ liability under acceptances 16,329 16,329 13,560 13,560 Other financial assets 10,913 10,913 9,314 9,314 Liabilities: Deposits 674,535 676,534 625,964 625,367 Financial instruments designated at fair value through profit or loss 8,188 8,188 4,663 4,663 Acceptances 16,338 16,338 13,560 13,560 Obligations related to securities sold short 32,087 32,087 30,766 30,766 Derivative financial instruments 37,967 37,967 34,200 34,200 Obligations related to securities sold under repurchase agreements and securities lent 101,257 101,257 95,843 95,843 Subordinated debentures 5,627 5,698 6,105 5,935 Other financial liabilities 35,432 34,805 27,531 27,118 Changes in interest rates, credit spreads and liquidity costs are the main cause of changes in the fair value of the Bank’s financial instruments resulting in a favourable or unfavourable variance compared to carrying value. 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. Fair value hierarchy The following table outlines the fair value hierarchy of instruments carried at fair value on a recurring basis and of instruments not carried at fair value. 2018 (1) 2017 As at October 31 ($ millions) Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Instruments carried at fair value on a recurring basis: Assets: Precious metals (2) $ – $ 3,175 $ 16 $ 3,191 $ – $ 5,717 $ – $ 5,717 Trading assets Loans – 14,334 – 14,334 – 17,312 – 17,312 Canadian federal government and government guaranteed debt 13,003 – – 13,003 10,343 – – 10,343 Canadian provincial and municipal debt – 10,159 – 10,159 – 7,325 – 7,325 US treasury and other US agencies’ debt 7,164 – – 7,164 6,894 – – 6,894 Other foreign governments’ debt 4,610 1,833 – 6,443 5,680 1,149 – 6,829 Corporate and other debt 3 8,984 18 (3) 9,005 44 7,920 22 7,986 Income funds 29 – – 29 180 165 – 345 Equity securities 39,513 158 – 39,671 38,760 170 – 38,930 Other (4) 454 – – 454 2,500 – – 2,500 $ 64,776 $ 38,643 $ 34 $ 103,453 $ 64,401 $ 39,758 $ 22 $ 104,181 Financial assets designated at fair value through profit or loss $ 12 $ – $ – $ 12 $ 13 $ – $ – $ 13 Investment securities (5) Canadian federal government and government guaranteed debt 6,373 2,518 – 8,891 9,677 2,416 – 12,093 Canadian provincial and municipal debt 366 3,986 – 4,352 593 4,230 – 4,823 US treasury and other US agencies’ debt 18,472 669 – 19,141 6,305 367 – 6,672 Other foreign governments’ debt 10,457 9,485 48 (6) 19,990 10,944 8,746 113 19,803 Corporate and other debt 732 1,818 13 (3) 2,563 750 3,584 53 4,387 Mortgage-backed securities – (7) 906 – 906 539 876 – 1,415 Equity securities 838 263 709 1,810 590 177 544 1,311 $ 37,238 $ 19,645 $ 770 $ 57,653 $ 29,398 $ 20,396 $ 710 $ 50,504 Derivative financial instruments Interest rate contracts $ – $ 8,927 $ 112 $ 9,039 $ – $ 9,742 $ 36 $ 9,778 Foreign exchange and gold contracts 5 22,197 – 22,202 4 21,496 – 21,500 Equity contracts 797 1,556 8 2,361 615 1,720 – 2,335 Credit contracts – 349 – 349 – 175 – 175 Commodity contracts 92 3,515 – 3,607 133 1,443 – 1,576 $ 894 $ 36,544 $ 120 $ 37,558 $ 752 $ 34,576 $ 36 $ 35,364 Liabilities: Deposits (8) $ – $ (401 ) $ – $ (401 ) $ – $ (7 ) $ – $ (7 ) Financial liabilities designated at fair value through profit or loss – 8,188 – 8,188 – 4,663 – 4,663 Obligations related to securities sold short 24,563 7,524 – 32,087 27,796 2,970 – 30,766 Derivative financial instruments Interest rate contracts – 11,012 74 11,086 – 10,823 267 11,090 Foreign exchange and gold contracts – 20,537 – 20,537 3 17,646 – 17,649 Equity contracts 1,057 1,884 5 2,946 502 2,724 7 3,233 Credit contracts – 70 – 70 – 179 – 179 Commodity contracts 34 3,294 – 3,328 268 1,781 – 2,049 $ 1,091 $ 36,797 $ 79 $ 37,967 $ 773 $ 33,153 $ 274 $ 34,200 Instruments not carried at fair value (9) Assets: Investment securities – amortized cost $ 7,392 (7) $ 12,815 $ 109 (6) $ 20,316 $ 4,240 $ 14,476 $ – $ 18,716 Loans (10) – 313,490 – 313,490 – – 286,621 286,621 Liabilities: Deposits (10)(11) – 293,898 – 293,898 – 266,995 – 266,995 Subordinated debentures – 5,627 – 5,627 – 6,105 – 6,105 Other liabilities – 20,383 – 20,383 – 13,363 – 13,363 (1) The amounts for October 31, 2018 have been prepared in accordance with IFRS 9, prior periods have not been restated (refer to Notes 3 and 4).

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 become available. The Bank recognizes transfers between levels of the fair value hierarchy as of the end of the reporting period during which the change has occurred. Derivative liabilities of $316 million were transferred out of Level 3 into Level 2 for the year ended October 31, 2018. All transfers were as a result of new information being obtained regarding the observability of inputs used in the valuation. The following significant transfers were made among Levels 2 and 3 for the year ended October 31, 2017: A net amount of derivative assets of $135 million and derivative liabilities of $126 million were transferred out of Level 3 into Level 2 for equity derivatives. Transfers were primarily as a result of assessment and consideration of volatility as an insignificant input for certain equity derivative contracts. Level 3 sensitivity analysis The table below sets out information about significant unobservable inputs used in measuring financial instruments categorized as Level 3 in the fair value hierarchy. Valuation technique Significant Range of estimates for (1) Changes in fair value Derivative financial instruments Interest rate contracts Option pricing Interest rate 7% - 93% – model volatility Equity contracts Option pricing Equity volatility 2% - 124% (9)/9 model Single stock correlation (70)% - 97% (1) The range of estimates represents the actual lowest and highest level inputs used to fair value financial instruments within each financial statement category. 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. Correlation Correlation in a credit derivative or debt instrument refers to the likelihood of a single default causing a succession of defaults. It affects the distribution of the defaults throughout the portfolio and therefore affects the valuation of instruments such as collateralized debt obligation tranches. A higher correlation may increase or decrease fair value depending on the seniority of the instrument. 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 is a measure of security price fluctuation. Historic volatility is often calculated as the annualized standard deviation of daily price variation for a given time period. Implied volatility is volatility, when input into an option pricing model, that returns a value equal to the current market value of the option.

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 investments, loans and 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 under a benchmark rate. The change in fair value attributable to change in credit risk is determined by the change in the cumulative fair value adjustment due to own credit risk. The following table presents the fair value of financial assets and 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, 2018. To control credit risk associated with derivatives, the Bank uses the same credit risk management activities and procedures that are used in the lending business in assessing and adjudicating potential credit exposure. The Bank applies limits to each counterparty, measures exposure as the current positive fair value plus potential future exposure, and uses credit mitigation techniques, such as netting and collateralization. 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). Derivatives 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, while credit protection is 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 taking into account master netting or collateral arrangements that have been made. The CRA does not reflect actual or expected losses. The credit equivalent amount (CEA) is the CRA plus an add-on add-on 2018 2017 As at October 31 ($ millions) Notional amount Credit risk (1) Credit (1) CET1 (2) Notional amount Credit risk (1) Credit (1) CET1 (2) Interest rate contracts Futures $ 127,595 $ – $ 93 $ – $ 161,590 $ – $ 65 $ – Forward rate agreements 330,433 36 157 82 330,061 20 30 20 Swaps 3,598,399 96 4,436 1,125 2,803,343 250 5,459 1,341 Options purchased 33,019 36 138 63 39,664 5 105 57 Options written 34,655 – 2 1 40,993 – 15 3 4,124,101 168 4,826 1,271 3,375,651 275 5,674 1,421 Foreign exchange and gold contracts Futures 7,476 – 85 – 32,452 – 56 – Spot and forwards 466,548 2,571 5,440 2,006 448,735 2,370 6,311 1,765 Swaps 397,994 4,297 8,232 2,604 384,867 4,023 7,297 1,898 Options purchased 42,545 712 240 76 39,116 523 515 113 Options written 41,804 – 20 5 40,028 – 83 12 956,367 7,580 14,017 4,691 945,198 6,916 14,262 3,788 Other derivative contracts Equity 123,305 455 4,927 1,505 101,390 45 5,123 1,575 Credit 29,866 239 420 119 37,592 12 1,421 174 Commodity and other contracts 100,576 1,182 8,052 830 87,415 9 10,953 807 253,747 1,876 13,399 2,454 226,397 66 17,497 2,556 Credit Valuation Adjustment (2) – – – 4,616 – – – 2,988 Total derivatives $ 5,334,215 $ 9,624 $ 32,242 $ 13,032 $ 4,547,246 $ 7,257 $ 37,433 $ 10,753 Amount settled through (3) Exchange-traded 236,956 – 7,300 153 282,132 – 10,385 208 Over-the-counter 3,523,060 – 781 16 2,693,460 – 1,334 27 $ 3,760,016 $ – $ 8,081 $ 169 $ 2,975,592 $ – $ 11,719 $ 235 (1) The amounts presented are net of collateral and master netting agreements at the product level.

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 rate risk exposure. In fair value hedges of interest rate risk, the interest rate exposure from fixed rate assets and liabilities is converted from a fixed to floating exposure. In cash flow hedges of interest rate risk, the interest rate exposure from floating rate assets and liabilities is converted from floating to fixed. The Bank generally hedges interest rate risk only to the extent of benchmark interest rates. The total interest cash flows usually comprise a spread in addition to the benchmark rate. Foreign currency risk In fair value hedges, cross-currency interest rate 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 and single-currency interest rate swaps are mainly used to convert a foreign currency fixed rate exposure to a functional currency floating rate exposure The Bank generally hedges interest rate risk only to the extent of benchmark interest rates. The total interest cash flows usually comprise a spread in addition to the benchmark 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 for interest cash flows in another currency. Single-currency interest rate swaps may be used in conjunction with cross-currency interest rate 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 and purchase considerations for business acquisitions 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. The total interest cash flows usually comprise a spread in addition to the benchmark 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 the underlying reference interest rate tenor and reset/settlement frequency 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 tables present current fiscal year information in accordance with these new disclosure requirements. Prior year comparatives have not been restated and are presented in accordance with the prior IFRS 7 disclosure requirements at the end of this section.

(e) Allowance for credit losses Key inputs and assumptions The Bank’s allowance calculations are outputs of complex models with a number of underlying assumptions regarding the choice of variable inputs. 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 which can result from changes to any of the above inputs and assumptions. (i) Key macroeconomic variables (i)(a) The following table shows certain key macroeconomic variables used in modelling the allowance for credit losses for Stages 1 and 2. For the base case, optimistic and pessimistic scenarios, the projections are provided for the next 12 months and for the remaining forecast period, which represents a medium-term view.

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 Housing Corporation (CMHC). MBS created under the program are 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 sale of mortgages under the above programs does not meet the derecognition requirements, as 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.

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 backstop liquidity facility 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 perform under its asset-specific LAPA agreements, in which case the Bank is obliged 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 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 The Bank uses funding vehicles to facilitate cost-efficient financing of its own operations, including the issuance of covered bonds and notes. These vehicles include Scotiabank Covered Bond Guarantor Limited Partnership, Halifax Receivables Trust, Trillium Credit Card Trust II and Securitized Term Auto Receivables Trust 2016-1, 2017-1, 2017-2, 2018-1 2018-2. Activities of these structured entities are generally limited to holding an interest in a pool of assets or receivables generated by the Bank. These structured entities are consolidated due to the Bank’s decision-making power and ability to use the power to affect the Bank’s returns. Scotiabank Covered Bond Guarantor Limited Partnership 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, 2018, $29.1 billion (2017 – $25.7 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 and Euros. As at October 31, 2018, assets pledged in relation to these covered bonds were uninsured residential mortgages denominated in Canadian dollars of $30.7 billion (2017 – $27.8 billion). Personal line of credit securitization trust The Bank securitizes a portion of its Canadian unsecured personal line of credit receivables (receivables) through Halifax Receivables Trust (Halifax), a Bank-sponsored structured entity. Halifax issues notes to third-party investors and the Bank, proceeds of which are used to purchase co-ownership The Bank is responsible for servicing the transferred receivables as well as performing administrative functions for Halifax. The subordinated notes issued by Halifax are held by the Bank. As at October 31, 2018, $1 billion notes (2017 – $1 billion) were outstanding and included in Deposits – Business and government on the Consolidated Statement of Financial Position. As at October 31, 2018, assets pledged in relation to these notes were $1.3 billion (2017 – $1.3 billion). Credit card receivables securitization trust The Bank securitizes a portion of its Canadian credit card receivables (receivables) through Trillium Credit Card Trust II (Trillium), a Bank-sponsored structured entity. Trillium issues notes to third-party investors and the Bank, and the proceeds of such issuance are used to purchase co-ownership The Bank is responsible for servicing the transferred receivables as well as performing administrative functions for Trillium. The subordinated notes issued by Trillium are held by the Bank. As at October 31, 2018, US $1.2 billion ($1.6 billion Canadian dollars) (2017 – US $0.9 billion, $1.2 billion Canadian dollars) Class A notes were outstanding and included in Deposits – Business and government on the Consolidated Statement of Financial Position. As at October 31, 2018 assets pledged in relation to these notes were credit card receivables, denominated in Canadian dollars, of $1.8 billion (2017 – $1.3 billion). Auto loan receivables securitization trusts The Bank securitizes a portion of its Canadian auto loan receivables (receivables) through Securitized Term Auto Receivables Trust 2016-1, 2017-1, 2017-2, 2018-1 2018-2 The Bank is responsible for servicing the transferred receivables as well as performing administrative functions for START. The subordinated notes and certain Class A notes issued by START are held by the Bank. As at October 31, 2018, the aggregate Class A notes issued to third parties outstanding and included in Deposits – Business and government on the Consolidated Statement of Financial Position were US $1.8 billion ($2.4 billion Canadian dollars) (2017 – US $1.6 billion, $2.1 billion Canadian dollars). As at October 31, 2018, assets pledged in relation to these notes were Canadian auto loan receivables denominated in Canadian dollars of $3 billion (2017 – $2.3 billion). Other Assets of other consolidated structured entities are comprised of securities, deposits with banks and other assets to meet the Bank’s and customer needs. (b) Unconsolidated structured entities The following table provides information about other structured entities in which the Bank has a significant interest but does not control and therefore does not consolidate. A significant interest is generally considered to exist where the Bank is exposed to 10% or more of the unconsolidated structured entities’ maximum exposure to loss. As at October 31, 2018 ($ millions) Canadian multi-seller Bank administers Structured Capital Total Total assets (on structured entity’s financial statements) $ 3,216 $ 4,488 $ 1,520 $ 9,224 Assets recognized on the Bank’s financial statements Trading assets 3 – – 3 Investment securities – 1,054 17 1,071 Loans (1) – 978 45 1,023 3 2,032 62 2,097 Liabilities recognized on the Bank’s financial statements Deposits – Business and government – – 1,458 1,458 Derivative financial instruments 6 – – 6 6 – 1,458 1,464 Bank’s maximum exposure to loss $ 3,219 $ 2,032 $ 62 $ 5,313 As at October 31, 2017 ($ millions) Canadian multi-seller Bank administers Structured Capital Total Total assets (on structured entity’s financial statements) $ 3,127 $ 3,991 $ 1,520 $ 8,638 Assets recognized on the Bank’s financial statements Trading assets – 5 – 5 Investment securities – 1,091 15 1,106 Loans (1) – 731 40 771 – 1,827 55 1,882 Liabilities recognized on the Bank’s financial statements Deposits – Business and government – – 1,465 1,465 Derivative financial instruments 6 – – 6 6 – 1,465 1,471 Bank’s maximum exposure to loss $ 3,127 $ 1,827 $ 55 $ 5,009 (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, 2018, the Bank has recorded $2 billion (2017 – $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 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 continuing involvement and obligations to determine if, in substance, the Bank is a sponsor. The Bank considers mutual funds and managed companies as sponsored entities. The following table provides information on revenue from unconsolidated Bank-sponsored entities. As at October 31 ($ millions) 2018 2017 Funds (1) Scotia Total Funds (1) Scotia Total Revenue $ 2,118 $ 3 $ 2,121 $ 2,016 $ 5 $ 2,021 (1) Includes mutual funds, other funds and trusts. The Bank earned revenue of $2,121 million (2017 – $2,021 million) from its involvement with the unconsolidated Bank-sponsored structured entities including mutual funds, for the year ended October 31, 2018, which was comprised of interest income of $1 million (2017 – $1 million), non-interest non-interest

Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill The changes in the carrying amounts of goodwill by cash-generating unit (CGU) are as follows: ($ millions) Canadian Global Latin Caribbean Total Balance as at October 31, 2016 $ 3,403 $ 265 $ 2,461 $ 1,255 $ 7,384 Acquisitions – – – – – Dispositions (36 ) – – – (36 ) Foreign currency adjustments and other 18 (10 ) (61 ) (52 ) (105 ) Balance as at October 31, 2017 3,385 255 2,400 1,203 7,243 Acquisitions 1,710 – 1,164 – 2,874 Dispositions – – – – – Foreign currency adjustments and other – 5 (110 ) (5 ) (110 ) Balance as at October 31, 2018 $ 5,095 $ 260 $ 3,454 $ 1,198 $ 10,007 Impairment testing of goodwill Goodwill acquired in business combinations is allocated to each of the Bank’s group of CGUs that are expected to benefit from the synergies of the particular acquisition. 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, and 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 is then compared to its respective carrying amount to identify any impairment. P/E multiples ranging from 11 to 13.5 times (2017 – 11 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, 2018 and July 31, 2017 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, 2018. Intangible assets Intangible assets consist of assets with indefinite and finite useful lives. Indefinite life intangible assets consist substantially of fund management contracts. The fund management contracts are for the management of open-ended funds. Finite life intangible assets include assets such as computer software, customer relationships and core deposit intangibles.

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 Indefinite life intangible assets were assessed for annual impairment as at July 31, 2018 and July 31, 2017 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, 2018.

The restructuring charge primarily related to employee severance and was recorded within non-interest Litigation and Other Other primarily includes provisions related to litigation. 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.

(10-day Other equity instruments Other equity instruments of $1,560 million (US$1.25 billion) include USD-denominated non-cumulative The terms of the notes are described below: • The price per note is USD $1,000, with interest paid semi-annually in arrears at 4.65% per annum, for the initial five years. Thereafter, the interest will reset quarterly and accrue at a rate per annum equal to three-month LIBOR plus 2.648%. • While interest is payable on a semi-annual basis for the initial five year period, and quarterly thereafter, the Bank may, at its discretion, with notice, cancel the payments. If the Bank does not pay the interest in full to the note holders, the Bank will not declare dividends on its common or preferred shares or redeem, purchase or otherwise retire such shares until the month commencing after the Bank resumes full interest payments on the notes. • The notes are redeemable at par 5 years after issuance solely at the option of the Bank, or following a regulatory or tax event, as described in the offering documents. All redemptions are subject to regulatory consent. • The notes are the Bank’s direct unsecured obligations, ranking subordinate to all of the Bank’s subordinated indebtedness. • NVCC provisions require the conversion of these capital instruments 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 mid-day The notes 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 date of issuance, the Bank has assigned an insignificant value to the 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, 2018, the Bank paid interest of US$58 million (2017 - nil) in respect of these notes. (c) Restrictions on dividend payments Under the Bank Act, the Bank is prohibited from declaring any dividends on its common or preferred shares when the Bank is, or would be placed by such a declaration, in contravention of the capital adequacy, liquidity or any other regulatory directives issued under the Bank Act. In addition, common share dividends cannot be paid unless all dividends to which preferred shareholders are then entitled have been paid or sufficient funds have been set aside to do so. 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. Similarly, should the Bank fail to declare regular dividends on any of its directly issued outstanding preferred or common shares, cash distributions will also not be made on any of the Scotiabank Trust Securities. In the event that distributions on the Bank’s subordinated additional Tier 1 capital securities (NVCC) are not paid in full, the Bank has undertaken not to declare dividends on its common or preferred shares until the month commencing after such distributions have been made in full. Currently, these limitations do not restrict the payment of dividends on 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, without the transitional phase-in ‘all-in’), (D-SIB), In addition to risk-based capital requirements, the Basel III reforms introduced a simpler, non risk-based Leverage ratio requirement to act as a supplementary measure to its risk-based capital requirements. Institutions are expected to maintain a material operating buffer above the 3% minimum. The Bank’s regulatory capital ratios were as follows: 2018 (3) 2017 As at October 31 ($ millions) All-in All-in Transitional Capital Common Equity Tier 1 Capital $ 44,443 $ 43,352 $ 46,051 Net Tier 1 Capital 50,187 49,473 50,623 Total regulatory capital 57,364 56,113 57,222 Risk-weighted assets/exposures used in calculation of capital ratios CET1 risk-weighted assets (1)(2) $ 400,507 $ 376,379 $ 387,292 Tier 1 risk-weighted assets (1)(2) 400,680 376,379 387,292 Total risk-weighted assets (1)(2) 400,853 376,379 387,292 Leverage exposures 1,119,099 1,052,891 1,053,928 Capital ratios Common Equity Tier 1 Capital ratio 11.1 % 11.5 % 11.9 % Tier 1 capital ratio 12.5 % 13.1 % 13.1 % Total capital ratio 14.3 % 14.9 % 14.8 % Leverage ratio 4.5 % 4.7 % 4.8 % (1) In accordance with OSFI’s requirements, scalars for CVA risk-weighted assets of 0.80, 0.83 and 0.86 (0.72, 0.77 and 0.81 in 2017) were used to compute the CET1 capital ratio, Tier 1 capital ratio and Total capital ratio, respectively.

The Basel I capital floor add-on add-on add-on: (3) The Transitional approach is no longer applicable effective Fiscal 2018.

Share-Based Payments	Share-Based Payments (a) Stock option plans The Bank grants stock options and stand-alone stock appreciation rights (SARs) as part of the Employee Stock Option Plan. Options to purchase common shares and/or to receive an equivalent cash payment, as applicable, may be granted to selected employees at an exercise price of the higher of the closing price of the Bank’s common shares on the Toronto Stock Exchange (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. As approved by the shareholders, a total of 129 million common shares have been reserved for issuance under the Bank’s Employee Stock Option Plan of which 106.8 million common shares have been issued as a result of the exercise of options and 14 million common shares are committed under outstanding options, leaving 8.2 million common shares available for issuance as options. Outstanding options expire on dates ranging from December 5, 2018 to December 7, 2027. 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 plans include: ● Tandem stock appreciation rights Employee stock options granted between December 2, 2005 to November 1, 2009 have Tandem SARs, which provide the employee the choice to either exercise the stock option for shares, or to exercise the Tandem SARs and thereby receive the intrinsic value of the stock option in cash. As at October 31, 2018, 3,900 Tandem SARs were outstanding (2017 – 5,900). The share-based payment liability recognized for vested Tandem SARs as at October 31, 2018 was $0.1 million (2017 – nil). The corresponding intrinsic value of this liability as at October 31, 2018 was $0.2 million (2017 – nil). In 2018, an expense of $0.6 million (2017 – $0.4 million expense) was recorded in salaries and employee benefits in the Consolidated Statement of Income. This expense is net of losses arising from derivatives used to manage the volatility of share-based payments of nil (2017 – $0.3 million gains). ● Stock options Employee stock options granted beginning December 2009 are equity-classified stock options which call for settlement in shares and do not have Tandem SARs features. The amount recorded in equity – other reserves for vested stock options as at October 31, 2018 was $164 million (2017 – $177 million). In 2018, an expense of $7 million (2017 – $7 million) was recorded in salaries and employee benefits in the Consolidated Statement of Income. As at October 31, 2018, future unrecognized compensation cost for non-vested ● Stock appreciation rights Stand-alone SARs are granted instead of stock options to selected 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 2018, 53,056 SARs were granted (2017 – 60,840) and as at October 31, 2018, 1,073,146 SARs were outstanding (2017 – 1,275,608), of which 1,032,495 SARs were vested (2017 – 1,229,330). The share-based payment liability recognized for vested SARs as at October 31, 2018 was $14 million (2017 – $31 million). The corresponding intrinsic value of this liability as at October 31, 2018 was $27 million (2017 – $28 million). In 2018, a benefit of $3 million (2017 – benefit of $2 million) was recorded in salaries and employee benefits in the Consolidated Statement of Income. This benefit is net of losses arising from derivatives used to manage the volatility of share-based payment of $8 million (2017 – $20 million gains). Determination of fair values The share-based payment liability and corresponding expense for SARs and options with Tandem SAR features were quantified using the Black-Scholes option pricing model with the following assumptions and resulting fair value per award: As at October 31 2018 2017 Assumptions Risk-free interest rate% 2.26% - 2.34% 1.38% - 1.59% Expected dividend yield 4.58% 3.61% Expected price volatility 13.75% - 28.12% 15.3% - 23.38% Expected life of option 0.00 - 4.58 0.00 - 4.53 Fair value Weighted-average fair value $ 13.39 $ 25.72 The share-based payment expense for stock options, i.e., without Tandem SAR features, was quantified using the Black-Scholes option pricing model on the date of grant. The fiscal 2018 and 2017 stock option grants were fair valued using the following weighted-average assumptions and resulting fair value per award: 2018 Grant 2017 Grant Assumptions Risk-free interest rate % 1.73% 1.27% Expected dividend yield 3.62% 3.81% Expected price volatility 15.86% 17.24% Expected life of option 6.64 years 6.67 years Fair value Weighted-average fair value $ 7.68 $ 6.51 The risk-free rate is based on Canadian treasury bond rates interpolated for the maturity equal to the expected life until exercise of the options. Expected dividend yield is based on historical dividend payout. Expected price volatility is determined based on the historical volatility for compensation. For accounting purposes, an average of the market consensus implied volatility for traded options on our common shares and the historical volatility is used.

(2) Includes options of 3,900 Tandem SARs (2017 – 5,900) and 130,000 options originally issued under HollisWealth plans (2017 – 156,520). (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% of eligible contributions, up to a maximum dollar amount, which is expensed in salaries and employee benefits. During 2018, the Bank’s contributions totalled $55 million (2017 – $54 million). Contributions, which are used to purchase common shares in the open market, do not result in a subsequent expense to the Bank from share price appreciation. As at October 31, 2018, an aggregate of 16 million common shares were held under the employee share ownership plans (2017 – 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. These 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 a portion of the Performance Share Unit notional 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 2018, an aggregate expense of $188 million (2017 – $203 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 payment of $85 million (2017 – $160 million gains). As at October 31, 2018, the share-based payment liability recognized for vested awards under these plans was $745 million (2017 – $946 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, 2018, there were 939,290 units (2017 – 755,472) awarded and outstanding of which 795,783 units were vested (2017 – 684,017). Directors’ Deferred Stock Unit Plan (DDSU) Under the DDSU Plan, non-officer Restricted Share Unit Plan (RSU) Under the RSU Plan, selected 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, 2018, there were 2,639,165 units (2017 – 2,197,100) awarded and outstanding of which 1,665,885 were vested (2017 – 1,497,340). Performance Share Unit Plan (PSU) Eligible executives receive an award of performance share units, for the majority of grants vest at the end of three years. One grant provides for a graduated vesting schedule which includes a specific performance factor calculation. A portion of the 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 outstanding shares 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, 2018, there were 7,813,011 units (2017 – 8,250,143) outstanding subject to performance criteria, of which 6,403,107 units were vested (2017 – 6,718,738). Deferred Performance Plan Under the Deferred Performance Plan, a portion of the bonus received by Global Banking and Markets employees (which is accrued and expensed in the year to which it relates) is allocated to qualifying employees in the form of units. These units are subsequently paid in cash to the employees over each of the following three years. Changes in the value of the units, which arise from fluctuations in the market price of the Bank’s common shares, are expensed in the same manner as the Bank’s other liability-classified share-based payment plans in the salaries and employee benefits expense in the Consolidated Statement of Income. As at October 31, 2018, there were 1,251,576 units outstanding (2017 – 1,587,037). November 30, 2017 was the last grant under this plan, there will be no further grants.

As a result, the net deferred tax assets of $733 (2017 – $1,016) are represented by deferred tax assets of $1,938 (2017 – $1,713), and deferred tax liabilities of $1,205 (2017 – $697) on the Consolidated Statement of Financial Position. The major changes to net deferred taxes were as follows: For the year ended October 31 ($ millions) 2018 2017 Balance at beginning of year $ 1,016 $ 1,410 Deferred tax benefit (expense) for the year recorded in income 3 (178 ) Deferred tax benefit (expense) for the year recorded in equity 193 (198 ) Acquired in business combinations (493 ) – Other 14 (18 ) Balance at end of year $ 733 $ 1,016 The tax related to temporary differences, unused tax losses and unused tax credits for which no deferred tax asset is recognized in the Consolidated Statement of Financial Position amounts to $14 million (October 31, 2017 – $82 million). The amount related to unrecognized losses is $7 million, which will expire as follows: $1 million in 2020 and beyond and $6 million in 2023. Included in the net deferred tax asset are tax benefits of $92 million (2017 – $92 million) that have been recognized in certain Canadian and foreign subsidiaries that have incurred losses 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, 2018 is approximately $33 billion (2017 – $27 billion). Reassessment of dividend deductions In November 2016, the Bank received a federal reassessment of $179 million for tax and interest as a result of the Canada Revenue Agency denying the tax deductibility of certain Canadian dividends received during the 2011 taxation year. In August 2017, the Bank received a reassessment of $185 million for tax and interest for the 2012 taxation year. The circumstances of the dividends subject to the reassessment are similar to those prospectively addressed by recently enacted rules which had been introduced in the 2015 Canadian federal budget. In June 2018, the Bank received a reassessment of $211 million for tax and interest in respect of the same circumstances for the 2013 taxation year. 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.

Employee Benefits

Text block1 [abstract]
Employee Benefits	28 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, the US, Mexico, the 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, a defined benefit pension plan (which includes an optional defined contribution (DC) component for employees in Canada hired on or after January 1, 2016) which was recently amended to include a defined contribution pension plan for employees in Canada hired on or after May 1, 2018 (the defined benefit provision of the pension plan is closed to employees hired on or after May 1, 2018). 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 Resources Committee (HRC) of the Board approves the charter of the Pension Administration and Investment Committee (PAIC), reviews reports, and approves the investment policy. The HRC also reviews and recommends any amendments to the SPP to the Board of Directors. • PAIC is responsible for recommending the investment policy to the HRC, for appointing and monitoring investment managers, and for reviewing auditor and actuary reports. PAIC also monitors the administration of member pension benefits. • 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. PAIC and the MTC both have independent member representation on the committees. • 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, 2017. Contributions are being made to the SPP in accordance with this valuation and are shown in the table in b) below. The assumptions used for the funding valuation are set by independent plan actuaries on the basis of the requirements of the Canadian Institute of Actuaries and applicable regulation. Other benefit plans The principal other benefit plans include plans in Canada, the US, Mexico, Uruguay, the 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 at the beginning of the period. 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 longer than expected; and/or • 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, 2018 SPP Other International Canada International Percentage of total benefit obligations 70 % 14 % 16 % 58 % 42 % Percentage of total plan assets 72 % 9 % 19 % 16 % 84 % Percentage of total benefit expense (1) 82 % 16 % 2 % 39 % 61 % Pension plans Other benefit plans Canada For the year ended October 31, 2017 SPP Other International Canada International Percentage of total benefit obligations 74 % 11 % 15 % 63 % 37 % Percentage of total plan assets 76 % 6 % 18 % 18 % 82 % Percentage of total benefit expense (1) 80 % 16 % 4 % 51 % 49 % (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 2018, and the two prior years.

A key factor in managing long-term investment risk is asset mix. Investing the pension assets in 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. The use of derivatives is generally prohibited 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 strategy. Actual asset mix is reviewed regularly, and rebalancing back to target asset mix is considered – as needed – generally on a semi-annual basis. The Bank’s other benefit plans are generally not funded, with the exception of certain programs in Canada and Mexico. The tables below shows the weighted-average actual and target asset allocations for the Bank’s principal plans at October 31, by asset category.

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 three business lines: Canadian Banking, International Banking and Global Banking and Markets. 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, 2018 (1) Taxable equivalent basis ($ millions) Canadian International Global Banking Other (2) Total Net interest income (3) $ 7,898 $ 7,322 $ 1,454 $ (483 ) $ 16,191 Non-interest (4) 5,452 4,111 3,074 (53 ) 12,584 Total revenues 13,350 11,433 4,528 (536 ) 28,775 Provision for credit losses 794 1,867 (50 ) – 2,611 Depreciation and amortization 460 304 69 15 848 Non-interest 6,194 5,807 2,164 45 14,210 Income tax expense 1,538 706 587 (449 ) 2,382 Net income $ 4,364 $ 2,749 $ 1,758 $ (147 ) $ 8,724 Net income attributable to non-controlling – 176 – – 176 Net income attributable to equity holders of the Bank 4,364 2,573 1,758 (147 ) 8,548 Average assets ($ billions) 342 168 321 115 946 Average liabilities ($ billions) 254 131 265 232 882 (1) The amounts for the year ended October 31, 2018 have been prepared in accordance with IFRS 9; prior period amounts have not been restated (refer to Notes 3 and 4).

Financial Instruments - Risk Management	37 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, 2018: • 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 effective 2011 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, for probability of default (PD), loss given default (LGD) and exposure at default (EAD), as defined below: • EAD: Generally represents the expected gross exposure – outstanding amount for on-balance off-balance • PD: Measures the likelihood that a borrower will default within a 1-year • LGD: Measures the severity of loss on a facility in the event of a borrower’s default, expressed as a percentage of exposure at default. 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) 2018 2017 Exposure at default (1) Category Drawn (2) Undrawn Other (3) Total Total By counterparty type Non-retail AIRB portfolio Corporate $ 146,324 $ 83,885 $ 77,751 $ 307,960 $ 285,191 Bank 22,680 2,146 16,676 41,502 40,903 Sovereign 188,480 768 6,854 196,102 195,429 357,484 86,799 101,281 545,564 521,523 Standardized portfolio Corporate 59,018 5,313 3,802 68,133 59,164 Bank 3,208 160 143 3,511 2,619 Sovereign 5,299 31 6 5,336 6,337 67,525 5,504 3,951 76,980 68,120 Total non-retail $ 425,009 $ 92,303 $ 105,232 $ 622,544 $ 589,643 Retail AIRB portfolio Real estate secured 143,475 17,864 – 161,339 143,160 Qualifying revolving 17,337 28,550 – 45,887 44,384 Other retail 31,176 1,671 – 32,847 31,672 $ 191,988 $ 48,085 $ – $ 240,073 $ 219,216 Standardized portfolio Real estate secured 44,517 – – 44,517 34,002 Other retail 42,100 – – 42,100 35,552 86,617 – – 86,617 69,554 Total retail $ 278,605 $ 48,085 $ – $ 326,690 $ 288,770 Total $ 703,614 $ 140,388 $ 105,232 $ 949,234 $ 878,413 By geography (4) Canada $ 394,279 $ 89,776 $ 37,748 $ 521,803 $ 502,224 United States 102,265 33,103 42,771 178,139 157,386 Chile 47,048 1,038 5,066 53,152 27,190 Mexico 29,344 1,339 2,611 33,294 30,528 Peru 23,997 1,506 2,992 28,495 28,733 Colombia 12,729 486 434 13,649 10,859 Other International Europe 25,357 7,041 10,215 42,613 43,030 Caribbean 35,716 1,676 910 38,302 39,358 Latin America (other) 10,232 909 227 11,368 9,035 All other 22,647 3,514 2,258 28,419 30,070 Total $ 703,614 $ 140,388 $ 105,232 $ 949,234 $ 878,413 (1) Exposure at default is presented after credit risk mitigation.

(4) Amounts for AIRB exposures are reported gross of allowances and amounts for standardized exposures are reported net of allowances. (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. The Bank’s non-retail Internal grades (IG) are used to differentiate the risk of default of a borrower. The following table cross references the Bank’s internal borrower grades with equivalent ratings categories utilized by external rating agencies: Cross referencing of internal ratings to external ratings (1) Equivalent External Rating S&P Moody’s DBRS Internal Grade Internal Grade PD Range (2) AAA to AA+ Aaa to Aa1 AAA to AA (high) 99 – 98 0.0000% – 0.0448% AA to A+ Aa2 to A1 AA to A (high) 95 0.0448% – 0.1304% A to A- A2 to A3 A to A (low) Investment grade 90 0.0552% – 0.1402% BBB+ Baa1 BBB (high) 87 0.0876% – 0.2187% BBB Baa2 BBB 85 0.1251% – 0.3176% BBB- Baa3 BBB (low) 83 0.1788% – 0.4610% BB+ Ba1 BB (high) 80 0.2886% – 0.5134% BB Ba2 BB 77 0.4658% – 0.5716% BB- Ba3 BB (low) Non-Investment grade 75 0.5716% – 0.7518% B+ B1 B (high) 73 0.7518% – 1.4444% B to B- B2 to B3 B to B (low) 70 1.4444% – 2.7749% CCC+ Caa1 – 65 2.7749% – 10.1814% CCC Caa2 – Watch list 60 10.1814% – 19.4452% CCC- Caa3 to Ca – 40 19.4452% – 35.4088% – – – 30 35.4088% – 59.5053% Default Default 21 100% (1) Applies to non-retail (2) PD ranges overlap across IG codes as the Bank utilizes two risk rating systems for its AIRB portfolios, and each risk rating system has its own separate IG to PD mapping.

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, 2018, 43% 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) 2018 2017 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% $ – $ – $ 11,657 $ 498 $ 12,155 $ 16,026 Very Low 0.0500% – 0.1999% 41,146 32,079 9,348 6,971 89,544 80,507 Low 0.2000% – 0.9999% 73,094 5,130 12,091 16,721 107,036 94,081 Medium Low 1.0000% – 2.9999% 6,494 1,068 7,893 5,123 20,578 17,070 Medium 3.0000% – 9.9999% 738 310 3,594 2,569 7,211 8,583 High 10.0000% – 19.9999% 345 185 354 486 1,370 889 Extremely High 20.0000% – 99.9999% 416 69 803 303 1,591 1,453 Default 100% 195 70 147 176 588 607 Total $ 122,428 $ 38,911 $ 45,887 $ 32,847 $ 240,073 $ 219,216 (1) After credit risk mitigation. Retail standardized portfolio The retail standardized portfolio of $87 billion as at October 31, 2018 (2017 – $70 billion) was comprised of residential mortgages, personal loans, credit cards and lines of credit to individuals, mainly in the Latin American and Caribbean region. Of the total retail standardized exposures, $45 billion (2017 –$34 billion) was represented by mortgages and loans secured by residential real estate, mostly with a 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, 2018, the approximate market value of cash and securities collateral accepted that may be sold or repledged by the Bank was $136 billion (2017 – $115 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 36(d) details the nature and extent of the Bank’s asset pledging activities. Asset pledging transactions are conducted under terms that are common and customary to standard derivative, securities financing, and other borrowing activities. Standard risk management controls are applied with respect to asset pledging. Assets acquired in exchange for loans The carrying value of assets acquired in exchange for loans as at October 31, 2018 was $426 million (2017 – $412 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, and gap analysis. 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, inclusive of credit spread 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; mortgage prepayment rates; changes in the market price of credit; and the creditworthiness of a particular issuer. 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 shareholders’ equity. The income limit measures the effect of a specified shift in interest rates on the Bank’s annual net 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 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 after-tax impact on the Bank’s net interest income over the next twelve months and economic value of shareholders’ equity of an immediate and sustained 100 basis point increase and decrease in interest rates across major currencies as defined by the Bank. As at October 31 ($ millions) 2018 2017 Net income Economic value of equity Canadian Other Total Canadian Other Total Net Economic value 100 bp increase $ (181 ) $ 76 $ (105 ) $ (458 ) $ (412 ) $ (870 ) $ 64 $ (354 ) 100 bp decrease $ 177 $ (76 ) $ 101 $ 291 $ 506 $ 797 $ (67 ) $ 183 (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, 2018, a one percent increase (decrease) in the Canadian dollar against all currencies in which the Bank operates decreases (increases) the Bank’s before-tax (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, VaR, and stress-test 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, whether direct or indirect, to which the Bank is exposed due to inadequate or failed internal processes or systems, human error, or external events. Operational risk includes legal and regulatory risk, business process and change risk, fiduciary or disclosure breaches, technology failure, financial crime and environmental risk. Operational risk, in some form, exists in each of the Bank’s businesses and support activities, and can result in financial loss, regulatory sanctions and damage to the Bank’s reputation. The Bank has developed policies, processes and assessment methodologies to ensure that operational risk is appropriately identified and managed with effective controls with a view to safeguarding client assets and preserving shareholder value.

(2) Comprised of fund management contracts of $290 and trademark of $18. Goodwill of $556 million largely reflects the value of synergies expected by combining certain operations within the Bank’s asset management businesses as well as Jarislowsky Fraser’s strong market presence and future growth prospects. Citibank’s consumer and small and medium enterprise operations, Colombia On June 30, 2018, the Bank’s Colombian subsidiary, Scotiabank Colpatria S.A., completed the previously announced acquisition of Citibank’s consumer (retail and credit cards) and small and medium enterprise operations in Colombia. The acquired business forms part of the Bank’s International Banking business segment. The Bank has not finalized its initial accounting for the acquisition as it is still completing its valuation of the assets acquired and liabilities assumed. As at October 31, 2018, $2.0 billion of assets (mainly loans of $1.9 billion) and $1.4 billion of liabilities (mainly deposits of $1.3 billion) have been recorded. Subsequent adjustment during the measurement period will occur as the Bank completes its estimation of fair values of assets acquired and liabilities assumed. BBVA, Chile On July 6, 2018, the Bank acquired 68.2% of Banco Bilbao Vizcaya Argentaria, Chile, 100% of BBVA Seguros Vida S.A., 100% of Servicios Corporativos S.A., 68.1% of Inmobiliaria e Inversiones S.A. and 4.1% of Inversiones DCV S.A. (together “BBVA Chile”) in Chile for cash consideration of US$ 2.2 billion, following receipt of regulatory approvals in Chile and Canada. The Bank consolidated 100% of BBVA Chile’s assets and liabilities and recorded a non-controlling On September 1, 2018, BBVA Chile merged with Scotiabank Chile. The minority shareholder in BBVA Chile paid the Bank US$ 0.4 billion to increase their pro forma ownership of the merged entity. Subsequent to these transactions, the Bank retained control over the combined entity with 75.5% of the total shares. Under this agreement, the non-controlling shareholders have the option to sell all or a portion of their shares to the Bank at the then fair value, which can be settled, at the Bank’s discretion, by the issuance of common shares or cash. Based on the current estimates of acquisition date fair values, the Bank has estimated and recorded loans of $19.9 billion, other assets of $8.4 billion and an aggregate amount of goodwill and intangibles of $1.3 billion. Simultaneously, the Bank has recorded deposits of $13.4 billion and other liabilities of $12.8 billion. The Bank had recorded a non-controlling MD Financial Management, Canada On October 3, 2018, the Bank completed the previously announced acquisition of MD Financial Management (“MD Financial”) from the Canadian Medical Association, (“CMA”), for approximately $2.7 billion, payable in cash. MD Financial is Canada’s leading provider of financial services to physicians and their families, with approximately $49 billion in assets under management and administration. The acquired business forms part of the Canadian Banking business segment. On closing, the Bank and the CMA entered into a 10- Based on current estimates of acquisition date fair values, the Bank has estimated and recorded approximately $1.9 billion of indefinite life intangibles, goodwill of $1.2 billion, $70 million of finite life intangibles, $0.5 billion of deferred tax liabilities and $0.1 billion of other net assets acquired. The purchase price allocation is considered to be preliminary and will be refined as the Bank completes its valuation of the fair value of assets acquired and liabilities assumed. Aggregate impact to Consolidated Income For the year ended October 31, 2018, all four acquisitions contributed revenue of $394 million in aggregate and a net loss of $257 million in aggregate. The primary reason for the net loss is the recording of a provision for credit losses of $404 million ($285 million after-tax) on acquired performing financial assets, as required under IFRS 9. Acquisition costs directly related to the four acquisitions of $44 million are included in non-interest expenses in the Consolidated Statement of Income. Acquisitions announced but not closed Banco Cencosud, Peru On May 9, 2018, the Bank announced that Scotiabank Peru, its wholly owned subsidiary, has reached an agreement to acquire a 51% controlling interest in Banco Cencosud, which offers credit cards and consumer loans in Peru, for approximately $130 million. Under the terms of the agreement, the two companies will also enter into a 15-year Subject to regulatory approvals and closing conditions the acquisition is expected to close in the first quarter of 2019. Banco Dominicano del Progreso, Dominican Republic On August 14, 2018, the Bank announced that it has reached an agreement to acquire Banco Dominicano del Progreso, S.A. – Banco Múltiple (Banco Dominicano del Progreso), a bank with operations in the Dominican Republic, subject to regulatory approval. The transaction is not considered financially material to the Bank. Subject to regulatory approvals and closing conditions the acquisition is expected to close in the first quarter of 2019.

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 and exclude associates and joint arrangements. 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. The Bank controls an investee 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. For the Bank to control an entity, all of the 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. Non-controlling non-controlling 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). 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 may become involved with structured entities either at the formation stage or at a later date. The Bank controls an investee 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. Significant influence is ordinarily presumed to exist when the Bank holds between 20% and 50% of the voting rights. The Bank may also be able to exercise significant influence through board representation. The effects of potential voting rights that are currently exercisable or convertible are considered in assessing whether the Bank has significant influence. 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. If there is a loss of significant influence and the investment ceases to be an associate, equity accounting is discontinued from the date of loss of significant influence. If the retained interest on the date of loss of significant influence is a financial asset, it is measured at fair value and the difference between the fair value and the carrying value is recorded as an unrealized gain or loss in the Consolidated Statement of Income. 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 A joint arrangement is an arrangement over which two or more parties have joint control. Joint control exists only when decisions about the relevant activities (i.e., those that significantly affect the returns of the arrangement) require the unanimous consent of the parties sharing the control of the arrangement. Investments in joint arrangements 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. If there is a loss of joint control and it does not result in the Bank having significant influence over the joint venture, equity accounting is discontinued from the date of loss of joint control. If the retained interest in the former joint venture on the date of loss of joint control is a financial asset, it is measured at fair value and the difference between the fair value and the carrying value is recorded as an unrealized gain or loss in the Consolidated Statement of Income.
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 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 consideration paid. 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 effective November 1, 2017 Classification and measurement Classification and measurement of financial assets Financial assets 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 Financial assets include both debt and equity instruments. 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 Business model assessment involves determining how financial assets are managed in order to generate cash flows. The Bank’s business model assessment is based on the following categories: • Held to collect: The objective of the 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 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; • Whether the assets are held for trading purposes i.e., assets that the Bank acquires or incurs principally for the purpose of selling or repurchasing in the near term, or holds as part of a portfolio that is managed together for short-term profit or position taking; • 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 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 calculated 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 amortised cost is recognised in OCI with a corresponding charge to Provision for credit losses in the Consolidated Statement of Income. The accumulated allowance recognised 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 Financial assets classified in this category are those that have been designated by the Bank upon initial recognition, and once designated, the designation is irrevocable. The FVTPL designation is available only for those financial assets for which a reliable estimate of fair value can be obtained. Financial assets are designated at FVTPL if doing so eliminates or significantly reduces an accounting mismatch which would otherwise arise. Financial assets 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 Non-interest Equity instruments measured at FVOCI At initial recognition, there is an irrevocable option for the Bank 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 are 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 Financial liabilities classified in this category are those that have been designated by the Bank upon initial recognition, and once designated, the designation is irrevocable. The FVTPL designation is available only for those financial liabilities for which a reliable estimate of fair value can be obtained. Financial liabilities are designated at FVTPL when one of the following criteria is met: • 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 accordance 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 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. Unadjusted quoted market prices for identical instruments represent a Level 1 valuation. When quoted market prices are not available, the Bank maximizes the use of observable inputs within valuation models. When all significant inputs are observable, 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 only 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 permits a measurement exception that allows an entity to determine the fair value of a group of financial assets and liabilities with offsetting risks based on the sale or transfer of its net exposure to a particular risk (or risks). The Bank has adopted this exception through an accounting policy choice. Consequently, the fair values of certain portfolios of financial instruments are determined based on the net exposure of those instruments to particular market, credit or funding risk. 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 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. 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. 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, taking into account 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. To reflect this, 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 three probability-weighted forward-looking scenarios. The Bank considers both internal and external sources of information and data in order to achieve an 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 two 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 Income Statement. 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 income statement. 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, with the exception of 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 Impaired (PCI) loans. 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. Classification and measurement, derecognition, and impairment of financial instruments effective prior to November 1, 2017 Trading assets and liabilities Trading assets and liabilities 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 Investment securities Investment securities are comprised of available-for-sale held-to-maturity Available-for-sale Available-for-sale available-for-sale held-for-trading Available-for-sale non-monetary available-for-sale, available-for-sale Premiums, discounts and related transaction costs on available-for-sale Transaction costs on available-for-sale Held-to-maturity Held-to-maturity non-derivative held-for-trading, available-for-sale. held-to-maturity A sale or reclassification of a more than an insignificant amount of held-to-maturity held-to-maturity available-for-sale, held-to-maturity • Sales or reclassifications that are so close to maturity that changes in the market rate of interest would not have a significant effect on the financial asset’s fair value; • Sales or reclassifications after the Bank has collected substantially all of the asset’s original principal; or • Sales or reclassifications attributable to non-recurring Impairment of investment securities Investment securities are evaluated for impairment at the end of each reporting period, or more frequently if events or changes in circumstances indicate the existence of objective evidence of impairment. In the case of equity instruments classified as available-for-sale, available-for-sale held-to-maturity When a decline in value of available-for-sale non-interest The losses arising from impairment of held-to-maturity non-interest Reversals of impairment losses on available-for-sale non-interest available-for-sale Reversals of impairment losses on held-to-maturity non-interest Financial assets and liabilities designated at fair value through profit or loss Financial assets and financial liabilities classified in this category are those that have been designated by the Bank on initial recognition. The Bank may only designate an instrument at fair value through profit or loss when one of the following criteria is met, and designation is determined on an instrument by instrument basis: • The designation eliminates or significantly reduces the inconsistent treatment that would otherwise arise from measuring the assets or liabilities on a different basis; or • The assets and liabilities are part of a group of financial assets, financial liabilities or both which are managed together and their performance evaluated on a fair value basis, in accordance with a documented risk management or investment strategy and the information about the group is provided to key management personnel and it can be demonstrated that significant financial risks are eliminated or significantly reduced; or • The financial instrument contains one or more embedded derivatives which significantly modify the cash flows otherwise required. Financial assets and financial liabilities designated at fair value through profit or loss are recorded in the Consolidated Statement of Financial Position at fair value. For assets designated at fair value through profit or loss, changes in fair value are recognized in the Consolidated Statement of Income. For liabilities designated at fair value through profit or loss, changes in fair value arising from changes in the Bank’s own credit risk are recognized in the Consolidated Statement of Comprehensive Income (OCI), without subsequent reclassification to the Consolidated Statement of Income, unless doing so would create or increase an accounting mismatch. All other changes in fair value are recognized in the Consolidated Statement of Income. Loans Loans include loans and advances originated or purchased by the Bank which are not classified as held-for-trading, held-to-maturity available-for-sale Loans originated by the Bank are recognized when cash is advanced to a borrower. Loans purchased are recognized when cash consideration is paid by the Bank. Loans are measured at amortized cost using the effective interest method, less any impairment losses. Loans are stated net of allowance for credit losses.
Derecognition of financial assets and liabilities	Derecognition of financial assets and liabilities Derecognition of financial assets 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. 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. 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. Loan impairment and allowance for credit losses: The Bank considers a loan to be impaired when there is objective evidence of impairment as a result of one or more loss events that occurred after the date of initial recognition of the loan and the loss event has an impact on the estimated future cash flows of the loan that can be reliably estimated. Objective evidence is represented by observable data that comes to the attention of the Bank and includes events that indicate: • significant financial difficulty of the borrower; • a default or delinquency in interest or principal payments; • a high probability of the borrower entering a phase of bankruptcy or a financial reorganization; • a measurable decrease in the estimated future cash flows from the loan or the underlying assets that back the loan. If a payment on a loan is contractually 90 days in arrears, the loan will be classified as impaired, if not already classified as such, unless the loan is fully secured, the collection of the debt is in process, and the collection efforts are reasonably expected to result in repayment of the loan or in restoring it to a current status within 180 days from the date a payment has become contractually in arrears. Finally, a loan that is contractually 180 days in arrears is classified as impaired in all situations, except when it is guaranteed or insured by the Canadian government, the provinces or a Canadian government agency; such loans are classified as impaired if the loan is contractually in arrears for 365 days. Any credit card loan that has a payment that is contractually 180 days in arrears is written off. Losses expected as a result of future events are not recognized. The Bank considers evidence of impairment for loans and advances at both an individual and collective level. Individual impairment allowance For all loans that are considered individually significant, the Bank assesses on a case-by-case For those loans where objective evidence of impairment exists and the Bank has determined the loan to be impaired, impairment losses are determined based on the Bank’s aggregate exposure to the customer considering the following factors: • the customer’s ability to generate sufficient cash flow to service debt obligations; • the extent of other creditors’ commitments ranking ahead of, or pari passu with, the Bank and the likelihood of other creditors continuing to support the company; • the complexity of determining the aggregate amount and ranking of all creditor claims and the extent to which legal and insurance uncertainties are evident; and • the realizable value of security (or other credit mitigants) and likelihood of successful repossession. Impairment losses are calculated by discounting the expected future cash flows of a loan at its original effective interest rate, and comparing the resultant present value with the loan’s current carrying amount. This results in interest income being recognized using the original effective interest rate. Collective impairment allowance For loans that have not been individually assessed as being impaired, the Bank pools them into groups to assess them on a collective basis. Collective allowances are calculated for impaired loans and performing loans. Allowances related to performing loans estimate probable incurred losses that are inherent in the portfolio but have not yet been specifically identified as impaired. Internal risk rating parameters are used in the calculation of the collective impairment allowance. For non-retail • Probability of Default rates (PD) which are based upon the internal risk rating for each borrower; • Loss Given Default rates (LGD); and • Exposure at Default factors (EAD). Funded exposures are multiplied by the borrower’s PD and by the relevant LGD parameter. Committed but undrawn exposures are multiplied by the borrower’s PD, by the relevant LGD parameter, and by the relevant EAD parameter. A model stress component is also applied to recognize uncertainty in the credit risk parameters and the fact that current actual loss rates may differ from the long-term averages included in the model. Retail loans Retail loans represented by residential mortgages, credit cards and other personal loans are considered by the Bank to be homogeneous groups of loans that are not considered individually significant. All homogeneous groups of loans are assessed for impairment on a collective basis. Mortgages are collectively assessed for impairment, taking into account number of days past due, historical loss experience and incorporating both quantitative and qualitative factors including the current business and economic environment and the realizable value of collateral to determine the appropriate level of the collective impairment allowance. A roll rate methodology is used to determine impairment losses on a collective basis for credit cards and other personal loans because individual loan assessment is impracticable. Under this methodology, loans with similar credit characteristics are grouped into ranges according to the number of days past due and statistical analysis is used to estimate the likelihood that loans in each range will progress through the various stages of delinquency and ultimately prove irrecoverable. This methodology employs statistical analyses of historical data and experience of delinquency and default to estimate the amount of loans that will eventually be written off as a result of the events not identifiable on an individual loan basis. When the portfolio size is small or when information is insufficient or not reliable enough to adopt a roll rate methodology, the Bank adopts a basic formulaic approach based on historical loss rate experience. Performing loans Over and above the individually assessed and retail roll rate allowances, loans that were subject to individual assessment for which no evidence of impairment existed, are grouped together according to their credit risk characteristics for the purpose of reassessing them on a collective basis. This reflects impairment losses that the Bank has incurred as a result of events that have occurred but where the individual loss has not been identified. The collective impairment allowance for such loans is determined after taking into account: • historical loss experience in portfolios of similar credit risk characteristics (for example, by industry sector, loan grade or product); • the estimated period between impairment occurring and the loss being identified and evidenced by the establishment of an appropriate allowance against the individual loan; and • management’s experienced judgment as to whether current economic and credit conditions are such that the actual level of inherent losses at the reporting date is likely to be greater or less than that suggested by historical experience. As soon as information becomes available which identifies losses on individual loans within the group, those loans are removed from the group and assessed on an individual basis for impairment. Provision for credit losses on off-balance A provision is set up for the Bank’s off-balance off-balance Write-off Loans (and the related impairment allowance accounts) are normally written off, either partially or in full, when there is no realistic prospect of recovery. Where loans are secured, write-off write-off Reversals of impairment If the amount of an impairment loss related to loans decreases in a subsequent period, and the decrease can be related objectively to an event occurring after the impairment was recognized, the excess is written back by reducing the loan impairment allowance account accordingly. The write-back is recognized in the provision for credit losses in the Consolidated Statement of Income. Restructured loans Restructured loans include loans where the Bank has renegotiated the original terms of a loan by granting a concession to the borrower (concessions). These concessions include interest rate adjustments, deferral or extension of principal or interest payments and forgiveness of a portion of principal or interest. Once the terms of the loan have been renegotiated and agreed upon with the borrower the loan is considered a restructured loan. The investment in the loan is reduced as of the date of the restructuring to the amount of the net expected cash flows receivable under the modified terms, discounted at the original effective interest rate inherent in the loan. The loan is no longer considered past due and the reduction in the carrying value of the loan is recognized as a charge for loan impairment in the Consolidated Statement of Income in the period in which the loan is restructured. In other cases, restructuring may be considered substantial enough to result in recognition of a new loan. 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 currently 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 comprises cash, cash equivalents, demand deposits with banks and other financial institutions, highly liquid investments that are readily convertible to cash, subject to 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 fair value less costs to sell are credited or charged to non-interest Securities purchased and sold under resale agreements Securities purchased under resale agreements (reverse repurchase agreements) involve the Bank to purchase securities 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) involve the Bank to sell securities 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 in excess of, 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 method in interest income on 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 repurchase agreement or securities purchased under reverse repurchase agreement, respectively. Interest on cash collateral advanced or received is presented in interest income – securities purchased under resale agreements and securities borrowed or interest expense – other, respectively. Fees received and paid are reported as fee and commission revenues and expenses in the Consolidated Statement of Income, respectively. 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, commodities, 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 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 a combined basis with the host contracts although they are separated for measurement purposes when conditions requiring separation are met. Subsequent changes in fair value of embedded derivatives 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 only 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. 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 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. Hedge ineffectiveness is measured and recorded in non-interest 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 non-interest 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 is recognized in income. For hedges that are discontinued, the cumulative unrealized gain or loss recognized in other comprehensive income is reclassified to non-interest non-interest 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, buildings 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 – 40 years, building fittings – 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 Investment property Investment property is property held either for rental income or for capital appreciation or for both. The Bank holds certain investment properties which are presented in property and equipment on the Consolidated Statement of Financial Position. Investment property is carried at cost less accumulated depreciation and any accumulated impairment losses. Depreciation is calculated using the straight-line method over the estimated useful life of 40 years. Depreciation methods, useful lives and residual values are reassessed at each financial year-end
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 subsidiaries. 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 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. Goodwill impairment, at a standalone subsidiary level, may not in itself result in an impairment at the consolidated Bank level. The Bank determines the carrying value of the CGU using a regulatory capital approach based on credit, market, and 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, 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, cost 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 considered to be 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. 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 Bank as a lessor Assets leased to customers under agreements which transfer substantially all the risks and rewards of ownership, with or without ultimate legal title, are classified as finance leases and presented within loans in the Consolidated Statement of Financial Position. When assets held are subject to a finance lease, the leased assets are derecognized and a receivable is recognized which is equal to the present value of the minimum lease payments, discounted at the interest rate implicit in the lease. Initial direct costs incurred in negotiating and arranging a finance lease are incorporated into the receivable through the discount rate applied to the lease. Finance lease income is recognized over the lease term based on a pattern reflecting a constant periodic rate of return on the net investment in the finance lease. Finance lease income is included in the Consolidated Statement of Income under interest income from loans. Assets leased to customers under agreements which do not transfer substantially all the risks and rewards of ownership are classified as operating leases. The leased assets are included within property and equipment on the Bank’s Consolidated Statement of Financial Position. Rental income is recognized on a straight-line basis over the period of the lease in non-interest Bank as a lessee Assets held under finance leases are initially recognized as property and equipment in the Consolidated Statement of Financial Position at an amount equal to the fair value of the leased asset or, if lower, the present value of the minimum lease payments. The corresponding finance lease obligation is included in other liabilities in the Consolidated Statement of Financial Position. The discount rate used in calculating the present value of the minimum lease payments is the interest rate implicit in the lease. Contingent rentals are recognized as expense in the periods in which they are incurred. Operating lease rentals payable are recognized as an expense on a straight-line basis over the lease term, which commences when the lessee controls the physical use of the asset. Lease incentives are treated as a reduction of rental expense and are also recognized over the lease term on a straight-line basis. Contingent rentals arising under operating leases are recognized as an expense in the period in which they are incurred. Sale and lease-back Where the Bank enters into a sale leaseback transaction for a non-financial Leasehold improvements Leasehold improvements are investments made to customize buildings and offices occupied under operating lease contracts to make them suitable for their intended purpose. The present value of estimated reinstatement costs to bring a leased property into its original condition at the end of the lease, if required, is capitalized as part of the total leasehold improvements costs. At the same time, a corresponding liability is recognized to reflect the obligation incurred. Reinstatement costs are recognized in net income through depreciation of the capitalized leasehold improvements over their estimated useful life.
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 average earnings at retirement), 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 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 is the same as the rate used to determine the defined benefit obligation at the beginning of the period. 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, and administrative expense are recognized in net income. Net interest expense (income) is calculated by applying the discount rate at the beginning of the annual period 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 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 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 cost 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	Recognition of income and expenses Revenue is recognized to the extent that it is probable that the economic benefits will flow to the Bank and the revenue can be reliably measured. The following specific criteria must also be met before revenue is recognized: Interest and similar income and expenses For all non-trading 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 recognized when no other services are required of the Bank and the fees are non-refundable 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 effective interest on the loan. When it is unlikely that a loan will be drawn down, the loan commitment fees are recognized over the commitment period on a straight-line basis. Fee and commission revenues The Bank earns fee and commission revenues from a diverse range of services it provides to its customers. Fee income can be divided into the following two categories: Fees earned for the provision of services over a period of time are accrued over that period the services are provided. These fees include commission income, investment management, custody and other management and advisory fees. Investment management fees and custodial fees are mainly calculated as a percentage of daily or period-end Fees arising from negotiating or participating in the negotiation of a transaction for a third-party, such as the arrangement of the acquisition of shares or other securities or the purchase or sale of businesses, are recognized on completion of the underlying transaction. Fees or components of fees that are linked to a certain performance are recognized after fulfilling the corresponding criteria. 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 in Interest income when the Bank’s right to receive payment is established. 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 Employee stock options with tandem stock appreciation rights give the employee the right to exercise for shares or settle in cash. These options are classified as liabilities and are re-measured 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 tandem stock appreciation rights, 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 A voluntary renouncement of a tandem stock appreciation right where an employee retains the corresponding option for shares with no change in the overall fair value of the award, results in a reclassification of the accrued liability and associated tax to equity – other reserves in the Consolidated Statement of Financial Position. This reclassification is measured at the fair value of the renounced awards as of the renouncement date. Subsequent to the voluntary renouncement, these awards are accounted for as plain vanilla options, based on the fair value as of the renouncement date. Customer loyalty programs The Bank operates loyalty points programs, which allow customers to accumulate points when they use the Bank’s products and services. The points can then be redeemed for free or discounted products or services, subject to certain conditions. Consideration received is allocated between the products sold or services rendered and points issued, with the consideration allocated to points equal to their fair value. The fair value of points is generally based on equivalent retail prices for the mix of awards expected to be redeemed. The fair value of the points issued is deferred in other liabilities and recognized as banking revenues when the points are redeemed or lapsed. Management judgment is involved in determining the redemption rate to be used in the estimate of points to be redeemed.
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 three operating segments: Canadian Banking, International Banking, 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 Because of 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. Earnings are adjusted by the after-tax after-tax re-measurement 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
