Basis of Presentation	Note 1: Basis of Presentation Bank of Montreal (the bank or BMO) is a chartered bank under the Bank Act (Canada) These condensed interim consolidated financial statements have been prepared in accordance with International Accounting Standard (IAS) 34, Interim Financial Reporting Use of Estimates and Judgments The preparation of the interim consolidated financial statements requires management to make estimates and judgments that affect the carrying amounts of certain assets and liabilities, certain amounts reported in net income and other related disclosures. The most significant assets and liabilities for which we must make estimates and judgments include the allowance for credit losses (ACL); financial instruments measured at fair value; pension and other employee future benefits; impairment of securities and investments in associates and joint ventures; income taxes and deferred tax assets; goodwill and intangible assets; insurance contract liabilities; provisions including legal proceedings and severance charges; transfers of financial assets and consolidation of structured entities. We make judgments in assessing the business model for financial assets as well as whether substantially all risks and rewards have been transferred in respect of transfers of financial assets and whether we control structured entities. If actual results were to differ from the estimates, the impact would be recorded in future periods. The economic outlook is subject to several risks that could lead to a less favourable outcome for the North American economy. The most immediate threat is from potential new tariffs imposed by the U.S. Federal Government on U.S. imports and retaliatory actions by trading partners. The Canadian economy and businesses face additional long-term risks in the event of an unsuccessful renegotiation of the Canada-United States-Mexico Trade Agreement by 2026. The wildfires in Los Angeles will temporarily slow growth in California before extensive rebuilding in the years ahead. Other risks include the continued conflict in Ukraine, possible renewed conflict in the Middle East, heightened tensions between the United States and China over trade relations and Taiwan, and ongoing diplomatic tensions between Canada and India. The impact on our business, results of operations, reputation, financial performance and condition, including the potential for credit, counterparty and mark-to-market Allowance for Credit Losses As detailed further in Note 1 of our annual consolidated financial statements for the year ended October 31, 2024, ACL consists of allowances on impaired loans, which represent estimated losses related to impaired loans in the portfolio provided for but not yet written off, and allowances on performing loans, which is our best estimate of impairment in the existing portfolio for loans that have not yet been individually identified as impaired. The expected credit losses (ECL) model requires the recognition of credit losses generally based on 12 months of expected losses for performing loans and the recognition of lifetime losses on performing loans that have experienced a significant increase in credit risk since origination. The determination of a significant increase in credit risk takes into account many different factors and varies by product and risk segment. The bank’s methodology for determining a significant increase in credit risk is based on the change in probability of default between origination, and reporting date, assessed using probability-weighted scenarios as well as certain other criteria, such as 30 days past due and watchlist status. The assessment of a significant increase in credit risk requires experienced credit judgment. In determining whether there has been a significant increase in credit risk and in calculating the amount of ECL, we must rely on estimates and exercise judgment, based on what we know at the end of the reporting period, regarding matters for which the ultimate outcome is unknown. These judgments include changes in circumstances that may cause future assessments of credit risk to be materially different from current assessments, which could require an increase or a decrease in the ACL. The calculation of ECL includes the explicit incorporation of forecasts of future economic conditions. We have developed models incorporating specific macroeconomic variables that are relevant to each portfolio. Key economic variables for our retail portfolios include our primary operating markets of Canada, the United States and regional markets, where considered significant. Forecasts are developed internally by our Economics group, considering external data and our view of future economic conditions. We exercise experienced credit judgment to incorporate multiple economic forecasts, which are probability-weighted, in the determination of the final ECL. The allowance is sensitive to changes in both economic forecasts and the probability weight assigned to each forecast scenario. Additional information regarding the ACL is included in Note 3.

Loans and Allowance for Credit Losses	Note 3: Loans and Allowance for Credit Losses Allowance for Credit Losses The ACL 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 ACL amounted to $5,438 million as at January 31, 2025 ($4,936 million as at October 31, 2024) of which $4,792 million ($4,356 million as at October 31, 2024) was recorded in loans and $646 million ($580 million as at October 31, 2024) was recorded in other liabilities in our Consolidated Balance Sheet. Changes in gross balances, including originations, maturities, sales, write-offs and repayments in the normal course of operations, impact the ACL. The following tables show the continuity in the loss allowance by product type for the three months ended January 31, 2025 and January 31, 2024.

ECL Sensitivity and Key Economic Variables The ECL model requires the recognition of credit losses generally based on 12 months of expected losses for performing loans and the recognition of lifetime losses on performing loans that have experienced a significant increase in credit risk since origination. The allowance for performing loans is sensitive to changes in both economic forecasts and the probability-weight assigned to each forecast scenario. Many of the factors have a high degree of interdependency, although there is no single factor to which loan loss allowances as a whole are sensitive. The upside scenario as at January 31, 2025 assumes a stronger economic environment than the base case forecast, with lower unemployment rates. As at January 31, 2025, our base case scenario depicts an economic environment with modestly higher unemployment rates in the near-term, largely in response to previously elevated interest rates and tighter lending conditions, and a moderate economic recovery over the medium-term as inflation is expected to ease further and lead to lower interest rates. Our base case forecast as at October 31, 2024 broadly depicted a weak economic environment in the near term, while improving over the medium term. If we assumed a 100% weight on the base case forecast and included the impact of loan migration by restaging, with other assumptions held constant, including the application of experienced credit judgment, the allowance on performing loans would be approximately $2,675 million as at January 31, 2025 ($2,625 million as at October 31, 2024), compared to the reported allowance for performing loans of $4,480 million ($4,205 million as at October 31, 2024). As at January 31, 2025, our downside scenario involves an even Actual results in a recession will differ as our portfolio will change through time due to migration, growth, changes in geopolitical risks, risk mitigation actions and other factors. In addition, our allowance will reflect the four economic scenarios used in assessing the allowance, with often unequal weightings attached to each scenario, which can change through time. The following tables show the key economic variables used to estimate the allowance for performing loans forecast over the next 12 months or lifetime measurement period. The variables as at January 31, 2025 do not include the impact of tariffs on the economic outlook, but they do incorporate uncertainty with respect to their potential introduction. While the values disclosed below are national variables, we use regional variables in the underlying models and consider factors impacting particular industries where appropriate.

Other Equity Instruments The AT1 Notes and LRCNs are compound financial instruments that have both equity and liability features. On the date of issuance, we assigned an insignificant value to the liability components of both instruments and, as a result, the full amount of proceeds has been classified as equity and form part of our additional Tier 1 NVCC. Distributions on the AT1 Notes and LRCNs are recognized as a reduction in equity when payable. The AT1 Notes and LRCNs are subordinate to the claims of the depositors and certain other creditors in right of payment. Preferred Shares On November 25, 2024, we redeemed all of our outstanding 12 million Non-Cumulative 5-year Common Shares On January 17, 2025, we announced a normal course issuer bid (NCIB) to purchase up to 20 million of our common shares for cancellation commencing January 22, 2025, and ending no later than January 21, 2026. The timing and amount of purchases under the NCIB are determined by management, based on factors such as market conditions and capital levels. During the three months ended January 31, 2025, we purchased for cancellation 1.2 million common shares under the NCIB, at an average price of $144.43 per share for a total amount of $176 million, including tax.

Fair Value Hierarchy We use a fair value hierarchy to categorize assets and liabilities carried at fair value according to the inputs we use in valuation techniques to measure fair value. Valuation Techniques and Significant Inputs We determine the fair value of assets and liabilities 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 assets and liabilities using models such as discounted cash flows with observable market data for inputs, such as yields 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. Our Level 2 trading 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. Level 2 structured note liabilities are valued using models with observable market information. Level 2 derivative assets and liabilities are valued using industry standard models and observable market information. The extent of our use of actively quoted market prices (Level 1), internal models using observable market information as inputs (Level 2) and models using one or more significant unobservable inputs (Level 3) in the valuation of securities, loans classified as FVTPL and FVOCI, other assets, fair value liabilities, derivative assets and derivative liabilities is presented in the following table: (Canadian $ in millions) January 31, 2025 October 31, 2024 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Trading Securities Issued or guaranteed by: Canadian federal government $ 33 $ 9,720 $ - $ 9,753 $ 1,272 $ 8,764 $ - $  10,036 Canadian provincial and municipal governments - 7,789 - 7,789 - 7,585 - 7,585 U.S. federal government 3,748 25,435 - 29,183 2,688 21,560 - 24,248 U.S. states, municipalities and agencies - 653 - 653 - 565 - 565 Other governments 248 5,405 - 5,653 92 3,757 - 3,849 NHA MBS, and U.S. agency MBS and CMO - 51,769 - 51,769 - 40,995 - 40,995 Corporate debt - 12,176 - 12,176 - 10,172 - 10,172 Trading loans - 4,356 - 4,356 - 5,493 - 5,493 Corporate equity 61,450 476 6 61,932 65,559 420 4 65,983   65,479  117,779 6  183,264 69,611 99,311 4  168,926 FVTPL Securities Issued or guaranteed by: Canadian federal government - 703 - 703 166 237 - 403 Canadian provincial and municipal governments - 1,623 - 1,623 - 1,578 - 1,578 U.S. federal government - 1,547 - 1,547 - 1,527 - 1,527 Other governments - - - - - 25 - 25 NHA MBS, and U.S. agency MBS and CMO - 22 - 22 - 21 - 21 Corporate debt - 9,072 33 9,105 - 8,745 35 8,780 Corporate equity 996 905 5,202 7,103 921 910 4,899 6,730 996 13,872    5,235 20,103    1,087   13,043    4,934 19,064 FVOCI Securities Issued or guaranteed by: Canadian federal government - 37,832 - 37,832 3,212 30,965 - 34,177 Canadian provincial and municipal governments - 6,061 - 6,061 - 5,996 - 5,996 U.S. federal government - 16,973 - 16,973 25 16,940 - 16,965 U.S. states, municipalities and agencies - 4,946 - 4,946 - 5,068 - 5,068 Other governments - 6,246 - 6,246 - 5,656 - 5,656 NHA MBS, and U.S. agency MBS and CMO - 23,743 - 23,743 - 21,293 - 21,293 Corporate debt - 4,293 - 4,293 - 4,370 - 4,370 Corporate equity - - 163 163 - - 177 177 - 100,094 163 100,257 3,237 90,288 177 93,702 Loans Residential mortgages - 66 - 66 - 163 - 163 Business and government loans - 12,856 321 13,177 - 12,190 302 12,492 - 12,922 321 13,243 - 12,353 302 12,655 Other Assets 15,629 - 1,841 17,470 11,236 - 1,717 12,953 Fair Value Liabilities Deposits (3) - 56,646 - 56,646 - 54,108 - 54,108 Securities sold but not yet purchased 10,593 33,454 - 44,047 10,631 24,399 - 35,030 Other liabilities (4) 1,861 25,903 - 27,764 1,754 19,110 - 20,864 12,454 116,003 - 128,457 12,385 97,617 - 110,002 Derivative Assets Interest rate contracts 65 10,379 - 10,444 36 9,851 - 9,887 Foreign exchange contracts 33 25,988 42 26,063 4 21,258 10 21,272 Commodity contracts 95 1,454 5 1,554 169 1,656 2 1,827 Equity contracts 114 14,322 13 14,449 539 13,718 - 14,257 Credit default swaps - 3 - 3 - 10 - 10 307 52,146 60 52,513 748 46,493 12 47,253 Derivative Liabilities Interest rate contracts 62 11,787 - 11,849 32 10,811 - 10,843 Foreign exchange contracts - 28,855 - 28,855 - 19,955 - 19,955 Commodity contracts 38 1,297 - 1,335 96 1,721 4 1,821 Equity contracts 37 24,266 2 24,305 75 25,596 2 25,673 Credit default swaps - 8 1 9 - 10 1 11 137 66,213 3 66,353 203 58,093 7 58,303  (1) Other assets include precious metals, segregated fund assets and investment properties in our insurance business, carbon credits, certain receivables and other items measured at fair value.  (2) Interest expense for liabilities carried at fair value is $720 million for the three months ended January 31, 2025 ($529 million for the three months ended January 31, 2024).

Quantitative Information about Level 3 Fair Value Measurements The table below presents the fair values of our significant Level 3 financial instruments measured at fair value on a recurring basis, the valuation techniques used to determine their fair values and the value ranges of significant unobservable inputs used in the valuations. We have not applied any other reasonably possible alternative assumptions to the significant Level 3 categories of private equity investments, as the net asset values are provided by the investment or fund managers.

These input ranges do not reflect the level of input uncertainty, but are affected by the specific underlying instruments within each product category. The input ranges will therefore vary from period to period based on the characteristics of the underlying instruments held at each balance sheet date.  na – not applicable 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 Level 1 and Level 2 are dependent on the recency of issuance and availability of quoted market prices in the active market. The following table presents significant transfers between Level 1 and Level 2 for the three months ended January 31, 2025 and January 31, 2024: (Canadian $ in millions) For the three months ended January 31, 2025 January 31, 2024 Level 1 to Level 2 Level 2 to Level 1 Level 1 to Level 2 Level 2 to Level 1 Trading securities $ 2,664 $ 1,440 $ 1,094 $ 97 FVTPL securities - - 168 - FVOCI securities 1,869 - 1,110 709 Securities sold but not yet purchased 1,737 1,986 2,060 26  Certain comparative figures have been reclassified to conform with the current period’s presentation.

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, 2025 January 31, 2024 Expected dividend yield 3.6% 4.5% Expected share price volatility 16.7%  17.4% - 17.6% Risk-free rate of return 2.8% 3.3% - 3.4% Expected period until exercise (in years) 6.5 - 7.0 6.5 - 7.0 Exercise price ($) 141.00 118.50  Changes to the input assumptions can result in different fair value estimates.

Earnings Per Share	Note 10: Earnings Per Share Basic earnings per share is calculated by dividing net income attributable to bank shareholders, after deducting dividends payable on preferred shares and distributions payable on other equity instruments, by the daily average number of fully paid common shares outstanding throughout the period. Diluted earnings per share is calculated in the same manner, with further adjustments made to reflect the dilutive impact of instruments convertible into our common shares. The following tables present our basic and diluted earnings per share: Basic Earnings Per Common Share (Canadian $ in millions, except as noted) For the three months ended January 31, 2025 January 31, 2024 Net income attributable to bank shareholders $ 2,134 $ 1,290 Dividends on preferred shares and distributions on other equity instruments (65 ) (40 ) Net income available to common shareholders $ 2,069 $ 1,250 Weighted-average number of common shares outstanding (in thousands)   729,564   723,751 Basic earnings per common share (Canadian $) $ 2.84 $ 1.73 Diluted Earnings Per Common Share (Canadian $ in millions, except as noted) For the three months ended January 31, 2025 January 31, 2024 Net income available to common shareholders $ 2,069 $ 1,250 Weighted-average number of common shares outstanding (in thousands) 729,564 723,751 Effect of dilutive instruments Stock options potentially exercisable (1) 6,245 3,816 Common shares potentially repurchased (5,119 ) (2,981 ) Weighted-average number of diluted common shares outstanding (in thousands) 730,690   724,586 Diluted earnings per common share (Canadian $) $ 2.83 $ 1.73  (1) In computing diluted earnings per share, we excluded average stock options outstanding of 482,948 with a weighted-average exercise price of $153.89 for the three months ended January 31, 2025 (2,991,066 with a weighted-average exercise price of $132.29 for the three months ended January 31, 2024), as the average share price for the periods did not exceed the exercise price.

Income Taxes	Note 11: Income Taxes Tax Assessments Canadian tax authorities have reassessed us for additional income tax and interest in an amount of approximately $1,465 million in respect of certain 2011-2018 Canadian corporate dividends. These reassessments denied certain dividend deductions on the basis that the dividends were received as part of a “dividend rental arrangement.” In general, the tax rules raised by the Canadian tax authorities were prospectively addressed in the 2015 and 2018 Canadian federal budgets. We filed Notices of Appeal with the Tax Court of Canada and the matter is in litigation. We remain of the view that our tax filing positions were appropriate and intend to challenge all reassessments. However, if such challenges are unsuccessful, the additional expense would negatively impact our net income.

These input ranges do not reflect the level of input uncertainty, but are affected by the specific underlying instruments within each product category. The input ranges will therefore vary from period to period based on the characteristics of the underlying instruments held at each balance sheet date.  na – not applicable

[1]The low and high input values represent the lowest and highest actual level of inputs used to value a group of financial instruments in a particular product category. These input ranges do not reflect the level of input uncertainty, but are affected by the specific underlying instruments within each product category. The input ranges will therefore vary from period to period based on the characteristics of the underlying instruments held at each balance sheet date.
