Section 308 states that except as otherwise specified by OSFI, the financial statements are to be prepared in accordance with IFRS. These condensed interim consolidated financial statements were prepared in accordance with International Accounting Standard 34, Interim Financial Reporting The condensed interim consolidated financial statements for the quarter ended January 31, 2019 have been approved by the Board of Directors for issue on February 26, 2019.

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.

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 to third-party investors. The Trust issues securities to third-party investors. The sale of mortgages under the above program 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. The following table provides the carrying amount of transferred assets that do not qualify for derecognition and the associated liabilities: As at ($ millions) January 31 (1) October 31 (1) Assets Carrying value of residential mortgage loans $ 20,439 $ 20,498 Other related assets (2) 2,963 2,679 Liabilities Carrying value of associated liabilities 21,173 21,459 (1) The fair value of the transferred assets is $23,755 (October 31, 2018 – $23,237) and the fair value of the associated liabilities is $22,560 (October 31, 2018 – $22,468) for a net position of $1,195 (October 31, 2018 – $769). (2) These include cash held in trust and trust permitted investment assets acquired as part of the principal reinvestment account that the Bank is required to maintain in order to participate in the programs. Securitization of personal lines of credit, credit cards and auto loans The Bank securitizes a portion of its unsecured personal lines of credit, credit card and auto loan receivables through consolidated structured entities. These receivables continue to be recognized on the Consolidated Statement of Financial Position as personal and credit cards loans. Securities sold under repurchase agreements and securities lent The Bank enters into transactions, such as repurchase agreements and securities lending agreements, where the Bank transfers assets under agreements to repurchase them on a future date and retains all the substantial risks and rewards associated with the assets. The transferred securities remain on the Consolidated Statement of Financial Position along with the cash collateral received from the counterparty that is classified as deposit liabilities. The following table provides the carrying amount of the transferred assets and the associated liabilities: As at ($ millions) January 31 (1) October 31 (1) Carrying value of securities associated with: Repurchase agreements (2) $ 91,557 $ 82,816 Securities lending agreements 56,450 49,718 Total 148,007 132,534 Carrying value of associated liabilities (3) $ 116,527 $ 101,257 (1) The fair value of transferred assets is $148,007 (October 31, 2018 – $132,534) and the fair value of the associated liabilities is $116,527 (October 31, 2018 – $101,257) for a net position of $31,480 (October 31, 2018 – $31,277).

Financial instruments	Financial instruments (a) 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. (i) 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. Credit risk exposures disclosed below are presented based on the Basel framework utilized by the Bank. The Bank uses the Advanced Internal Ratings-Based approach (AIRB) for all material Canadian, U.S. and European portfolios, and for a significant portion of the international corporate and commercial portfolios. The remaining portfolios, including other international portfolios, are treated under the standardized approach. Under the AIRB approach, the Bank uses internal risk parameter estimates, based on historical experience. 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 Exposure at default (1) As at January 31, 2019 October 31 ($ millions) AIRB Standardized Total Total By exposure sub-type Non-retail Drawn (2)(3) $ 356,655 $ 65,579 $ 422,234 $ 425,009 Undrawn commitments 89,393 5,139 94,532 92,303 Other exposures (4) 92,862 11,298 104,160 105,232 Total non-retail $ 538,910 $ 82,016 $ 620,926 $ 622,544 Retail Drawn (5) $ 195,020 $ 91,650 $ 286,670 $ 278,605 Undrawn commitments 47,729 – 47,729 48,085 Total retail $ 242,749 $ 91,650 $ 334,399 $ 326,690 Total $ 781,659 $ 173,666 $ 955,325 $ 949,234 (1) After credit risk mitigation and excludes equity securities and other assets. (2) Non-retail (3) Non-retail (4) Includes off-balance over-the-counter (5) Retail drawn includes residential mortgages, credit cards, lines of credit and other personal loans. Credit quality of non-retail The Bank’s non-retail Credit quality of retail exposures The Bank’s retail portfolios consist of a number of relatively small loans to a large number of borrowers. The portfolios are distributed across Canada and a wide range of countries. As such, the portfolios inherently have a high degree of diversification. In addition, as of January 31, 2019, 42% (October 31, 2018 – 43%) of the Canadian residential mortgage portfolio is insured. The average loan-to-value Retail standardized portfolio The retail standardized portfolio of $92 billion as at January 31, 2019 (October 31, 2018 – $87 billion), was comprised of residential mortgages, personal loans, credit cards and lines of credit to individuals, mainly in Latin America and the Caribbean. Of the total retail standardized exposures, $48 billion (October 31, 2018 – $45 billion) was represented by mortgages and loans secured by residential real estate, mostly with a loan-to-value (ii) 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/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. (iii) 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 among them, and their levels of volatility. Interest rate risk Interest rate risk is the risk of loss due to the following: changes in the level, slope and curvature of the yield curve; the volatility of interest rates; and mortgage prepayment rates. Non-trading Foreign currency risk is the risk of loss due to changes in spot and forward rates. As at January 31, 2019, a one per cent increase (decrease) in the Canadian dollar against all currencies in which the Bank operates decreases (increases) the Bank’s before-tax A similar change in the Canadian dollar as at January 31, 2019, would decrease (increase) the unrealized foreign currency translation gains in the accumulated other comprehensive income section of shareholders’ equity by approximately $391 million (October 31, 2018 – $384 million; January 31, 2018 – $334 million), net of hedging. Non-trading Equity risk is the risk of loss due to adverse movements in equity prices. The Bank is exposed to equity risk through its investment equity portfolios. The fair value of investment equity securities is shown in Note 7.

Operational risk includes legal and regulatory risk, business process and change risk, fiduciary or disclosure breaches, cyber risks, technology failure, financial crime and environmental risk. It exists in some form in every Bank business and function. Operational risk can not only result in financial loss, but also 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. (b) 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 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 following table presents the fair value of assets and liabilities designated at fair value through profit or loss and their changes in fair value.

(c) Financial instruments – fair value Fair value of financial instruments 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. Refer to Note 7 of the Bank’s consolidated financial statements in the 2018 Annual Report for the valuation techniques used to fair value its significant financial assets and liabilities.

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. 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 as Level 3. The following table outlines the fair value hierarchy and instruments carried at fair value on a recurring basis.

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. There were no significant transfers into and out of Level 3 during the three months ended January 31, 2019 and October 31, 2018. Level 3 sensitivity The Bank applies judgment in determining unobservable inputs used to calculate the fair value of Level 3 instruments. Refer to Note 7 of the Bank’s audited consolidated financial statements for the year ended October 31, 2018 for a description of the significant unobservable inputs for Level 3 instruments and the potential effect that a change in each unobservable input may have on the fair value measurement. There have been no significant changes to the Level 3 sensitivities during the quarter.

Corporate income taxes	21. Corporate income taxes 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 reassessments 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 for $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.
