In addition, we are developing future processes and internal controls to enable the application of IFRS 16 in 2019. The main impact for the Bank will be recording real estate leases on the balance sheet. Currently, most of our real estate leases are classified as operating leases, whereby we record lease expense over the term of the lease with no asset or liability recorded on the balance sheet other than any related leasehold improvements. Under IFRS 16, we will recognize a right-of-use When we adopt IFRS 16, we will recognize the cumulative effect of any changes in opening retained earnings with no changes to prior years.

Allowance for Credit Losses (“ACL”) The allowance for credit losses recorded in our Consolidated Balance Sheet is maintained at a level we consider adequate to absorb credit-related losses on our loans and other credit instruments. The allowance for credit losses amounted to $1,962 million at April 30, 2019 ($1,870 million at October 31, 2018) of which $1,710 million ($1,639 million at October 31, 2018) was recorded in loans and $252 million ($231 million at October 31, 2018) was recorded in other liabilities in our Consolidated Balance Sheet.

Transfer of Assets	Note 4: Transfer of Assets Loan Securitization We sell Canadian mortgage loans to bank-sponsored and third-party Canadian securitization programs, including the Canadian Mortgage Bond program, and directly to third-party investors under the NHA-MBS During the three and six months ended April 30, 2019, we sold $1,024 million and $2,864 million, respectively, of loans to these programs ($3,419 million and $4,418 million, respectively, for the three and six months ended April 30, 2018). The following table presents the carrying amount and fair value of transferred assets that did not qualify for derecognition and the associated liabilities: (Canadian $ in millions) April 30, 2019 October 31, 2018 Carrying amount of assets (1) Carrying amount of associated liabilities Carrying amount of assets (1) Carrying amount of associated liabilities Residential mortgages 6,072 5,569 Other related assets (2) 11,096 11,640 Total (3) 17,168 16,694 17,209 16,925 (1) Carrying amount of loans is net of allowance for credit losses. (2) Other related assets represent payments received on account of loans pledged under securitization that have not been applied against the associated liabilities. The payments received are held on behalf of the investors in the securitization vehicles until principal payments are required to be made on the associated liabilities. In order to compare all assets supporting the associated liabilities, this amount is added to the carrying amount of the securitized assets in the above table. (3) The fair values of assets and associated liabilities are $17,126 million and $16,869 million, respectively, as at April 30, 2019 ($17,105 million and $16,763 million, respectively, as at October 31, 2018).

We retain the mortgage servicing rights for these loans, which represent our continuing involvement. As at April 30, 2019, the carrying value of the mortgage servicing rights was $49 million ($52 million as at October 31, 2018).

Acquisitions	Note 5: Acquisitions KGS-Alpha On September 1, 2018, we completed the acquisition of the business of KGS, a U.S. fixed income broker-dealer specializing in U.S. mortgage and asset-backed securities in the institutional investor market, for cash consideration of US$304 million (CAD$397 million). During the three months ended January 31, 2019, the purchase price decreased to US$303 million (CAD$396 million) due to a post-closing adjustment based upon working capital. The acquisition was accounted for as a business combination, and the acquired business and corresponding goodwill are included in our Capital Markets reporting segment. As part of this acquisition, we acquired intangible assets of $49 million and goodwill of $54 million. The intangible assets are being amortized over three to fourteen years on an accelerated basis. Goodwill of $32 million related to this acquisition is deductible for tax purposes. The fair values of the assets acquired and liabilities assumed at the date of acquisition are as follows: (Canadian $ in millions) KGS Securities - trading 5,193 Securities borrowed or purchased under resale agreements 5,669 Goodwill and intangible assets 103 Other Assets 583 Total assets 11,548 Securities lent or sold under repurchase agreements 9,563 Securities sold but not yet purchased 1,431 Other liabilities 158 Purchase price 396 The purchase price allocation for KGS is subject to refinement as we complete the valuation of the assets acquired and liabilities assumed.

(1) Carrying value of loans is net of allowance. (2) Excludes $2,816 million of loans classified as FVTPL as at April 30, 2019 ($1,450 million as at October 31, 2018). (3) Excludes $16,142 million of structured note liabilities designated at fair value through profit or loss and accounted for at fair value ($14,186 million as at October 31, 2018). Financial Instruments Designated at Fair Value Most of our structured note liabilities included in deposits have been designated at fair value through profit or loss which aligns the accounting result with the way the portfolio is managed. The fair value and notional amount due at contractual maturity of these structured notes as at April 30, 2019 were $16,142 million and $15,701 million, respectively ($14,186 million and $14,548 million, respectively, as at October 31, 2018). The change in fair value of these structured notes was recorded as a decrease of $365 million and a decrease of $765 million in non-interest non-interest non-interest The cumulative change in fair value related to changes in our own credit spread that has been recognized since the notes were designated at fair value to April 30, 2019 was an unrealized loss of $345 million, of this an unrealized loss of $269 million was recorded in other comprehensive income, with an unrealized loss of $76 million recorded through the Consolidated Statement of Income prior to the adoption of IFRS 9 own credit provision in 2015. We designate certain securities held by our insurance subsidiaries that support our insurance liabilities at fair value through profit or loss since the actuarial calculation of insurance liabilities is based on the fair value of the investments supporting them. This designation aligns the accounting result with the way the portfolio is managed on a fair value basis. The change in fair value of the assets is recorded in non-interest non-interest We designate the obligation related to certain investment contracts in our insurance business at fair value through profit or loss, which eliminates a measurement inconsistency that would otherwise arise from measuring the investment contract liabilities and offsetting changes in the fair value of the investments supporting them on a different basis. The fair value of these investment contract liabilities as at April 30, 2019 of $952 million ($800 million as at October 31, 2018) is recorded in other liabilities in our Consolidated Balance Sheet. The change in fair value of these investment contract liabilities resulted in an increase of $24 million and an increase of $61 million in insurance claims, commissions, and changes in policy benefit liabilities, respectively, for the three and six months ended April 30, 2019 (an increase of $1 million and a decrease of $13 million, respectively, for the three and six months ended April 30, 2018). For the three and six months ended April 30, 2019, a decrease of $13 million and a decrease of $12 million, respectively, was recorded in other comprehensive income related to changes in our own credit spread (an increase of $8 million and a decrease of $2 million, respectively, for the three and six months ended April 30, 2018). Changes in the fair value of investments backing these investment contract liabilities are recorded in non-interest Fair Value Hierarchy We use a fair value hierarchy to categorize financial instruments according to the inputs we use in valuation techniques to measure fair value. Valuation Techniques and Significant Inputs We determine the fair value of publicly traded fixed maturity and equity securities using quoted prices in active markets (Level 1) when these are available. We exercise a degree of judgement in determining whether the market from which a quoted price has been obtained is active. When quoted prices in active markets are not available, we determine the fair value of financial instruments using models such as discounted cash flows with observable market data for inputs such as yield and prepayment rates or broker quotes and other third-party vendor quotes (Level 2). Fair value may also be determined using models where significant market inputs are not observable due to inactive markets or minimal market activity (Level 3). We maximize the use of market inputs to the extent possible. Our Level 2 trading and FVTPL securities are primarily valued using discounted cash flow models with observable spreads or broker quotes. The fair value of Level 2 FVOCI securities is determined using discounted cash flow models with observable spreads or third-party vendor quotes.

Significant Transfers Our policy is to record transfers of assets and liabilities between fair value hierarchy levels at their fair values as at the end of each reporting period, consistent with the date of the determination of fair value. Transfers between the various fair value hierarchy levels reflect changes in the availability of quoted market prices or observable market inputs that result from changes in market conditions. The following is a discussion of the significant transfers between Level 1, Level 2 and Level 3 balances for the three and six months ended April 30, 2019. As at April 30, 2019, we refined our judgement of whether quoted prices for fixed income securities were obtained from markets that are active or not in the determination of whether a security should be Level 1 or Level 2, with the result that certain securities are shown as a transfer to Level 2 in the quarter. During the three and six months ended April 30, 2019, $1,954 million and $3,658 million, respectively, of trading securities, $141 million and $464 million, respectively, of FVTPL securities, and $7,282 million and $7,889 million, respectively, of FVOCI securities were transferred from Level 1 to Level 2 due to our refined approach and reduced observability of the inputs used to value these securities. During the three and six months ended April 30, 2019, $2,700 million and $3,359 million, respectively, of trading securities, $248 million and $352 million, respectively, of FVTPL securities and $464 million and $1,575 million, respectively, of FVOCI securities were transferred from Level 2 to Level 1 due to increased availability of quoted prices in active markets. During the three and six months ended April 30, 2019, $26 million and $45 million, respectively, of trading securities were transferred from Level 2 to Level 3 due to changes in the market observability of inputs used in pricing these securities, $18 million and $35 million, respectively, were transferred from Level 3 to Level 2 due to the availability of observable price inputs used to value these securities.

During the six months ended April 30, 2019, we granted a total of 931,047 stock options (705,398 stock options during the six months ended April 30, 2018). The weighted-average fair value of options granted during the six months ended April 30, 2019 was $10.23 per option ($11.30 per option for the six months ended April 30, 2018). To determine the fair value of the stock option tranches (i.e. the portion that vests each year) on the grant date, the following ranges of values were used for each option pricing assumption: For stock options granted during the six months ended April 30, 2019 April 30, 2018 Expected dividend yield 5.7% 4.1% Expected share price volatility 20.0% - 20.1% 17.0% - 17.3% Risk-free rate of return 2.5% 2.1% Expected period until exercise (in years) 6.5 - 7.0 6.5 - 7.0 Exercise price ($) 89.90 100.63 Changes to the input assumptions can result in different fair value estimates.

Income Taxes	Note 12: Income Taxes During the quarter ended April 30, 2019, Canada Revenue Agency (CRA) proposed to reassess us for additional taxes and interest in an amount of approximately $250 million in respect of certain 2014 Canadian corporate dividends. In prior fiscal years, we were reassessed by the CRA for additional income taxes and interest of approximately $361 million for certain 2011-2013 Canadian corporate dividends. In its reassessments, the CRA denied dividend deductions on the basis that the dividends were received as part of a “dividend rental arrangement.” The tax rules raised by the CRA in the reassessments were prospectively addressed in the 2015 and 2018 Canadian Federal Budgets. In the future, we expect to be reassessed for significant income tax for similar activities in 2015 and subsequent years. We remain of the view that our tax filing positions were appropriate and intend to challenge any reassessment.

Income Taxes	During the quarter ended April 30, 2019, Canada Revenue Agency (CRA) proposed to reassess us for additional taxes and interest in an amount of approximately $250 million in respect of certain 2014 Canadian corporate dividends. In prior fiscal years, we were reassessed by the CRA for additional income taxes and interest of approximately $361 million for certain 2011-2013 Canadian corporate dividends. In its reassessments, the CRA denied dividend deductions on the basis that the dividends were received as part of a “dividend rental arrangement.” The tax rules raised by the CRA in the reassessments were prospectively addressed in the 2015 and 2018 Canadian Federal Budgets. In the future, we expect to be reassessed for significant income tax for similar activities in 2015 and subsequent years. We remain of the view that our tax filing positions were appropriate and intend to challenge any reassessment.
Operating Groups	Operating Groups We conduct our business through three operating groups, each of which has a distinct mandate. Our operating groups are Personal and Commercial Banking (“P&C”) (comprised of Canadian Personal and Commercial Banking (“Canadian P&C”) and U.S. Personal and Commercial Banking (“U.S. P&C”)), Wealth Management and BMO Capital Markets (“BMO CM”), along with a Corporate Services unit.
