Basis of Presentation	Note 1: Basis of Presentation Bank of Montreal (“the bank”) is a chartered bank under the Bank Act (Canada) These condensed interim consolidated financial statements have been prepared in accordance with International Accounting Standard 34, Interim Financial Reporting Leases , Uncertainty Over Income Tax Treatments Financial Instruments: Recognition and Measurement Financial Instruments: Disclosures Changes in Accounting Policy Lease s Effective November 1, 2019, we adopted IFRS 16 Leases The main impact for the bank is recording real estate leases on the balance sheet. Previously most of our real estate leases were classified as operating leases, whereby we recorded the lease expense over the lease term with no asset or liability recorded on the balance sheet other than related leasehold improvements. On adoption, we elected to exclude intangibles from the scope of lease accounting. We recalculated the right-of-use right-of-use right-of-use non-lease right-of-use On transition, we recognized the cumulative effect of adoption in opening retained earnings as at November 1, 2019 periods to the Consolidated Balance Sheet as at November 1, 2019 premises and equipment other and retained earnings The following table sets out a reconciliation of our operating lease commitments, as disclosed under IAS 17 Leases ere (Canadian $ in millions) November 1, 2019 Operating lease commitment at October 31, 2019 as disclosed in our consolidated financial statements 3,800 Discounted using the incremental borrowing rate at November 1, 2019 (310 ) Finance lease liabilities recognized as at October 31, 2019 41 Recognition exemption for l (13 ) Extension and termination options reasonably certain to be exercised 37 Executory costs not included in the lease liability (166 ) Leases signed but not yet started (1,222 ) Lease liabilities recognized at November 1, 2019 2,167 When measuring lease liabilities, we discounted lease payments using our incremental borrowing rate at November 1, 2019. The weighted-average rate applied was When we enter into new arrangements as a lessee, a right-of-use non-cancellable The right-of-use The lease liability accretes interest which is recognized in interest expense , liabilities Amounts relating to leases of low value are expensed when incurred in non-interest Uncertainty Over Income Tax Treatment Effective November 1, 2019, we adopted IFRIC 23. The Interpretation clarifies the recognition and measurement requirements in IAS 12 Income Taxes Interbank Offered Rate (“IBOR”) Reform Effective November 1, 2019, we early adopted the IASB’s Phase 1 amendments to IAS 39 and IFRS 7, which provide hedge accounting relief from the uncertainty arising from IBOR reform during the period prior to replacement of IBORs. These amendments modify certain hedge accounting requirements, allowing us to assume the interest rate benchmark on which the cash flows of the hedged item and the hedging instrument are based are not altered as a result of IBOR reform, allowing hedge accounting to continue. They also provide an exception from the requirement to discontinue hedge accounting if a hedging relationship does not meet the effectiveness requirements as a result of IBOR reform. Mandatory application of the amendments ends at the earlier of when the uncertainty regarding the timing and amount of interest rate benchmark-based cash flows is no longer present and discontinuation of the hedging relationship. Under IBOR reform, certain benchmark rates may be subject to discontinuance, changes in methodology, increased volatility or decreased liquidity during the transition from IBORs to alternative rates. Banks will cease rate submissions for the calculation of the London Interbank Offered Rates after December 31, 2021. In order to manage the transition from IBORs to alternative rates, our enterprise-wide IBOR Transition Office is evaluating potential changes to market infrastructures on our risk framework, models, systems and processes, and reviewing legal documents to ensure the bank is prepared prior to the cessation of IBORs. We will apply judgment with respect to the need for new or revised hedging relationships; however, given market uncertainty, the assessment of the impact on the bank’s hedging relationships and its mitigation plans are in the early stages. The notional amount of the derivatives likely subject to IBOR reform designated as hedging instruments that mature after December 31, 2021 was $85,727 million of USD LIBOR and $1,560 million of other potentially impacted IBORs as at November 1, 2019.

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. 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 observable market inputs to the extent possible.

The weighted-average fair value of options granted during the three months ended January 31, 2020 was $9.46 per option ($10.23 per option for the three months ended January 31, 2019). To determine the fair value of the stock option tranches (i.e. the portion that vests each year) on the grant date, the following ranges of values were used for each option pricing assumption: For stock options granted during the three months ended January 31, 2020 January 31, 2019 Expected dividend yield 4.3% 5.7% Expected share price volatility 15.4% 20.0% - 20.1% Risk-free rate of return 1.9% - 2.0% 2.5% Expected period until exercise (in years) 6.5 - 7.0 6.5 - 7.0 Exercise price ($) 101.47 89.90 Changes to the input assumptions can result in different fair value estimates.

Income Taxes

Income Taxes	3 Months Ended

Text Block [Abstract]
Income Taxes	Note 1 0 In prior fiscal years, the Canada Revenue Agency (CRA) reassessed us for additional taxes and interest in an amount of approximately $611 million in respect of certain 2011-2014 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.

Legal Proceedings	Note 12: Legal Proceedings The bank and its subsidiaries are party to legal proceedings, including regulatory investigations, in the ordinary course of business. BMO Nesbitt Burns Inc., BMO InvestorLine Inc. and BMO Trust Company are defending a class action claiming various monetary awards up to $419 million for the alleged non-disclosure of foreign exchange conversion spreads when converting foreign currency in registered accounts. At a January 2020 summary judgment motion, an Ontario court indicated it expects to make a liability finding against these subsidiaries. The court’s written decision, including any monetary award, is expected in the second quarter of 2020. The bank will review the decision when received and consider whether to appeal. While there is inherent difficulty in predicting the ultimate outcome of this or other proceedings, management does not expect the outcome of any of these proceedings, individually or in the aggregate, to have a material adverse effect on the consolidated financial position or the results of operations of the bank.
