Toronto, May 24, 2023 – For the second quarter ended April 30, 2023, BMO Financial Group recorded net income of $1,059 million or $1.30 per share on a reported basis, and net income of $2,216 million or $2.93 per share on an adjusted basis.

“Our performance this quarter reflects our highly-diversified business mix and the strength, size and stability of our balance sheet, which has been further enhanced by the successful acquisition of Bank of the West. Against the backdrop of an uncertain economic environment, our Canadian and U.S. personal and commercial banking businesses continued to deliver good pre-provision, pre-tax earnings, while our wealth and capital markets businesses were impacted by lower customer activity. These results were underpinned by continued strong asset quality and capital, with a CET1 ratio of 12.2% following the closing of the largest acquisition in our history,” said Darryl White, Chief Executive Officer, BMO Financial Group.

“This strong foundation and our proven track record of delivering resilient financial performance over time positions us well to support our Canadian and U.S. customers and communities with the advice, products and services they need to make real financial progress towards their goals. We are uniquely situated to offer integrated banking, wealth and capital markets products and leading digital experiences that differentiate us from our competitors and drive long-term value for our shareholders.”

“In addition, we continue to be acknowledged for our ethical business practices and how we live our purpose. For the sixth consecutive year, BMO was recognized as one of the World’s Most Ethical Companies by Ethisphere, the only bank in Canada to receive this award since its inception in 2007,” concluded Mr. White.

Concurrent with the release of results, BMO announced a third quarter 2023 dividend of $1.47 per common share, an increase of $0.04 from the prior quarter and an increase of $0.08 or 6% from the prior year. The quarterly dividend of $1.47 per common share is equivalent to an annual dividend of $5.88 per common share.

BMO Financial Group Second Quarter Report 2023 1

Significant Events

On February 1, 2023, we completed the acquisition of Bank of the West and its subsidiaries from BNP Paribas for a cash purchase price of US$13.8 billion. Bank of the West provides a broad range of banking products and services, primarily in the Western and Midwestern parts of the United States. The acquisition strengthens our position in North America with increased scale and greater access to growth opportunities in strategic new markets. We expect to complete the conversion of the Bank of the West customer accounts and systems to our respective BMO platforms by early September 2023. The impact of the acquisition is reflected in our current quarter and year-to-date results as a business combination, with operating results primarily allocated to our U.S. P&C and BMO Wealth Management businesses based on Bank of the West’s client segmentation and allocation methodologies, which may change after conversion.

On closing, we recognized purchase accounting fair value marks on Bank of the West’s loans and deposits of $3.0 billion and discounts on securities of $3.5 billion on our balance sheet in accordance with International Financial Reporting Standards (IFRS). As previously disclosed, to manage the exposure to capital from changes in the fair value of the assets and liabilities of Bank of the West due to changes in interest rates between the announcement and closing of the acquisition, we entered into interest rate swaps that resulted in cumulative mark-to-market gains of $5.7 billion. These swaps were largely offset from an interest rate risk perspective through the purchase of a portfolio of matched duration U.S. treasuries and other balance sheet instruments. On closing, the swaps were unwound and replaced with hedges, which in effect crystallized the unrealized loss position on our balance sheet. Accretion of the fair value marks and securities discounts will increase net interest income, and the amortization of the fair value hedge will decrease net interest income, both recorded in Corporate Services.

As part of the acquisition, we acquired a 51% interest in CLAAS Financial Services, LLC, a subsidiary of Bank of the West that provides lease and loan financing to commercial entities acquiring agricultural equipment. The fair value of ownership interests of other partners in CLAAS Financial Services, LLC was $16 million, and recorded in non-controlling interest on our balance sheet.

For more information on the acquisition of Bank of the West, refer to Note 12 of the unaudited interim consolidated financial statements.

Second Quarter 2023 Performance Review

Adjusted results in the current quarter and the prior year excluded the following items:

Initial provision for credit losses of $517 million ($705 million<br>pre-tax) on the purchased Bank of the West performing loan portfolio in the current quarter.
Acquisition and integration costs of $549 million ($727 million<br>pre-tax) in the current quarter and $28 million ($37 million pre-tax) in the prior year, recorded in non-interest<br>expense. The current quarter included $545 million ($722 million pre-tax) related to Bank of the West.
--- ---
Amortization of acquisition-related intangibles assets of $85 million ($115 million pre-tax) in the current quarter and $6 million ($8 million pre-tax) in the prior year, recorded in non-interest expense. The<br>current quarter included $77 million ($104 million pre-tax) related to Bank of the West.
--- ---
A legal provision of $6 million ($7 million pre-tax) related to a<br>lawsuit associated with a predecessor bank, M&I Marshall and Ilsley Bank, recorded in interest expense in the current quarter.
--- ---
Revenue of $2,612 million ($3,555 million pre-tax) in the prior<br>year related to the management of the impact of interest rate changes between the announcement and closing of the Bank of the West acquisition on its fair value and goodwill.
--- ---
A gain of $6 million ($8 million pre-tax) and expenses of<br>$15 million ($18 million pre-tax) in the prior year related to the sale of our EMEA and U.S. Asset Management business.
--- ---

Adjusted results and ratios in this Second Quarter 2023 Performance Review section are on a non-GAAP basis. Refer to the Non-GAAP and Other Financial Measures section for further information on adjusting items. The order in which the impact on net income is discussed in this section follows the order of revenue, expenses and provision for credit losses, regardless of their relative impact.

Reported net income decreased from the prior year, primarily due to the impact of the adjusting items noted above, and adjusted net income increased 1%, with higher revenue partially offset by higher expenses and provisions for credit losses. Net income increased in U.S. P&C due to the inclusion of Bank of the West and the impact of the stronger U.S. dollar, and decreased across all other operating groups. On a reported basis, Corporate Services recorded a net loss compared with net income in the prior year, and on an adjusted basis, Corporate Services recorded a higher net loss.

The impact of the acquisition of Bank of the West (BOTW) on our second quarter 2023 net income is reflected in the table below.

Canadian P&C

Reported net income was $861 million, a decrease of $79 million or 8% from the prior year, and adjusted net income was $864 million, a decrease of $77 million or 8%. Results reflected a 7% increase in revenue due to higher net interest income, driven by balance growth and higher margins, and lower non-interest revenue, more than offset by higher expenses and a higher provision for credit losses compared with the prior year.

U.S. P&C

Reported net income was $789 million, an increase of $201 million or 34% from the prior year, and adjusted net income was $866 million, an increase of $277 million or 47% from the prior year. The impact of the stronger U.S. dollar increased net income by 9%, revenue by 12%, and expenses by 14%.

On a U.S. dollar basis, reported net income was $581 million, an increase of $117 million or 25% from the prior year, and adjusted net income was $638 million, an increase of $173 million or 37%. Bank of the West contributed $107 million to reported net income and $163 million to adjusted net income. Underlying results reflected a 9% increase in revenue, primarily due to higher net interest income driven by higher net interest margins and loan balances, partially offset by higher expenses and a higher provision for credit losses.

BMO Wealth Management

Reported net income was $284 million and adjusted net income was $285 million, both decreasing $30 million or 10% from the prior year. Bank of the West contributed $25 million to reported net income and $26 million to adjusted net income. Wealth and Asset Management reported net income was $221 million, a decrease of $26 million or 11%, and adjusted net income was $222 million, a decrease of $26 million or 11%. Underlying results reflected a decrease in revenue, primarily due to the impact of weaker global markets and lower online brokerage volumes, and higher expenses. Insurance net income was $63 million, a decrease of $4 million or 5% from the prior year.

BMO Capital Markets

Reported net income was $380 million, a decrease of $68 million or 15% from the prior year, and adjusted net income was $388 million, a decrease of $65 million or 14%. Results reflected revenue growth of 1%, with higher revenue in both Global Markets and Investment and Corporate Banking, higher expenses and a lower provision for credit losses.

Corporate Services

Reported net loss was $1,255 million, compared with reported net income of $2,466 million in the prior year, and adjusted net loss was $187 million, compared with $111 million. Reported results decreased, primarily due to the adjusting items noted above. Adjusted results decreased, primarily due to lower revenue and higher expenses, partially offset by the impact of a more favourable tax rate in the current quarter.

Capital

BMO’s Common Equity Tier 1 (CET1) Ratio was 12.2% as at April 30, 2023, a decrease from 18.2% at the end of the first quarter of 2023, primarily due to the acquisition of Bank of the West.

Credit Quality

Total reported provision for credit losses was $1,023 million and total adjusted provision for credit losses was $318 million, compared with a reported and adjusted provision of $50 million in the prior year. The total provision for credit losses as a percentage of average net loans and acceptances ratio was 65 basis points on a reported basis and 20 basis points on an adjusted basis, compared with 4 basis points on both a reported and adjusted basis in the prior year. Adjusted provision for credit losses excluded the initial provision on the purchased Bank of the West performing loan portfolio of $705 million.

The provision for credit losses on impaired loans was $243 million, an increase of $123 million from the prior year, primarily due to higher provisions in Personal and Business Banking in our P&C businesses. The provision for credit losses on impaired loans as a percentage of average net loans and acceptances ratio was 16 basis points, compared with 10 basis points in the prior year.

The provision for credit losses on performing loans was $780 million on a reported basis and $75 million on an adjusted basis, compared with a reported and adjusted recovery of $70 million in the prior year. The $780 million provision for credit losses on performing loans in the current quarter included the initial provision on the purchased Bank of the West performing loan portfolio noted above. On an adjusted basis, the $75 million provision for credit losses on performing loans in the current quarter reflected portfolio credit migration, model changes and economic uncertainty, partially offset by a modest improvement in macro-economic variables, including the continued benefit from risk transfer transactions. The $70 million recovery of credit losses in the prior year largely reflected reduced uncertainty as a result of the improving pandemic environment, portfolio credit improvement and model changes, partially offset by a deteriorating economic outlook, increased adverse scenario weight and portfolio growth.

Refer to the Critical Accounting Estimates and Judgments section of BMO’s 2022 Annual Report and Note 4 of our audited annual consolidated financial statements for further information on the allowance for credit losses as at October 31, 2022.

Bank of Montreal’s management, under the supervision of the Chief Executive Officer and the Chief Financial Officer, has evaluated the effectiveness, as at April 30, 2023, of Bank of Montreal’s disclosure controls and procedures (as defined in the rules of the U.S. Securities and Exchange Commission and the Canadian Securities Administrators) and has concluded that such disclosure controls and procedures are effective.

During the quarter, the bank acquired Bank of the West, contributing $127 billion or 10% to total assets as at February 1, 2023. We are evaluating the effectiveness of internal control over financial reporting as we complete the integration of Bank of the West with BMO, and will make changes to our internal control framework, as necessary.

Other than mentioned above, there were no changes in our internal control over financial reporting during the quarter ended April 30, 2023, which materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Because of inherent limitations, disclosure controls and procedures and internal control over financial reporting can provide only reasonable assurance and may not prevent or detect misstatements.

As in prior quarters, Bank of Montreal’s Audit and Conduct Review Committee reviewed this document and Bank of Montreal’s Board of Directors approved the document prior to its release.

Caution Regarding Forward-Looking Statements

Bank of Montreal’s public communications often include written or oral forward-looking statements. Statements of this type are included in this document and may be included in other filings with Canadian securities regulators or the U.S. Securities and Exchange Commission, or in other communications. All such statements are made pursuant to the “safe harbor” provisions of, and are intended to be forward-looking statements under, the United States Private Securities Litigation Reform Act of 1995 and any applicable Canadian securities legislation. Forward-looking statements in this document may include, but are not limited to, statements with respect to our objectives and priorities for fiscal 2023 and beyond, our strategies or future actions, our targets and commitments (including with respect to our Climate Ambition and net zero emissions), expectations for our financial condition, capital position, the regulatory environment in which we operate, the results of, or outlook for, our operations or the Canadian, U.S. and international economies, plans for the combined operations of BMO and Bank of the West, the timing for converting Bank of the West customer accounts and systems onto our respective BMO platforms, and the financial, operational and capital impacts of the transaction, and include statements made by our management. Forward-looking statements are typically identified by words such as “will”, “would”, “should”, “believe”, “expect”, “anticipate”, “project”, “intend”, “estimate”, “plan”, “commit”, “target”, “may”, “schedule”, “forecast”, “outlook”, “seek” and “could” or negative or grammatical variations thereof.

By their nature, forward-looking statements require us to make assumptions and are subject to inherent risks and uncertainties, both general and specific in nature. There is significant risk that predictions, forecasts, conclusions or projections will not prove to be accurate, that our assumptions may not be correct, and that actual results may differ materially from such predictions, forecasts, conclusions or projections. We caution readers of this document not to place undue reliance on our forward-looking statements, as a number of factors – many of which are beyond our control and the effects of which can be difficult to predict – could cause actual future results, conditions, actions or events to differ materially from the targets, expectations, estimates or intentions expressed in the forward-looking statements.

The future outcomes that relate to forward-looking statements may be influenced by many factors, including, but not limited to: general economic and market conditions in the countries in which we operate, including labour challenges; the impact of adverse developments affecting the U.S. and global banking industry, including the risk of bank failures and liquidity concerns, the heightening of economic and market volatility, and regulatory responses to such developments; the anticipated benefits from acquisitions, including Bank of the West, such as potential synergies, accretion to adjusted earnings per share (EPS), and operational efficiencies, are not realized; changes to our credit ratings; the emergence or continuation of widespread health emergencies or pandemics, and their impact on local, national or international economies, as well as their heightening of certain risks that may affect our future results; information, privacy and cybersecurity, including the threat of data breaches, hacking, identity theft and corporate espionage, as well as the possibility of denial of service resulting from efforts targeted at causing system failure and service disruption; benchmark interest rate reforms; technological changes and technology resiliency; political conditions, including changes relating to, or affecting, economic or trade matters; climate change and other environmental and social risk; the Canadian housing market and consumer leverage; inflationary pressures; global supply-chain disruptions; changes in monetary, fiscal, or economic policy; changes in laws, including tax legislation and interpretation, or in supervisory expectations or requirements, including capital, interest rate and liquidity requirements and guidance, and the effect of such changes on funding costs; weak, volatile or illiquid capital or credit markets; the level of competition in the geographic and business areas in which we operate; exposure to, and the resolution of, significant litigation or regulatory matters, our ability to successfully appeal adverse outcomes of such matters and the timing, determination and recovery of amounts related to such matters; the accuracy and completeness of the information we obtain with respect to our customers and counterparties; failure of third parties to comply with their obligations to us; our ability to execute our strategic plans, complete proposed acquisitions or dispositions and integrate acquisitions, including obtaining regulatory approvals; critical accounting estimates and judgments, and the effects of changes to accounting standards, rules and interpretations on these estimates; operational and infrastructure risks, including with respect to reliance on third parties; global capital markets activities; the possible effects on our business of war or terrorist activities; natural disasters and disruptions to public infrastructure, such as transportation, communications, power or water supply; and our ability to anticipate and effectively manage risks arising from all of the foregoing factors.

We caution that the foregoing list is not exhaustive of all possible factors. Other factors and risks could adversely affect our results. For more information, please refer to the discussion in the Risks That May Affect Future Results section, and the sections related to credit and counterparty, market, insurance, liquidity and funding, operational non-financial, legal and regulatory, strategic, environmental and social, and reputation risk, in the Enterprise-Wide Risk Management section of BMO’s 2022 Annual Report, and the Risk Management section in this document, all of which outline certain key factors and risks that may affect our future results. Investors and others should carefully consider these factors and risks, as well as other uncertainties and potential events, and the inherent uncertainty of forward-looking statements. We do not undertake to update any forward-looking statements, whether written or oral, that may be made from time to time by the organization or on its behalf, except as required by law. The forward-looking information contained in this document is presented for the purpose of assisting shareholders and analysts in understanding our financial position as at and for the periods ended on the dates presented, as well as our strategic priorities and objectives, and may not be appropriate for other purposes.

Material economic assumptions underlying the forward-looking statements contained in this document include those set out in the Economic Developments and Outlook section of BMO’s 2022 Annual Report, as updated in the Economic Developments and Outlook section in our Second Quarter 2023 Report to Shareholders, as well as in the Allowance for Credit Losses section of BMO’s 2022 Annual Report, as updated in the Allowance for Credit Losses section in our Second Quarter 2023 Report to Shareholders. Assumptions about the performance of the Canadian and U.S. economies, as well as overall market conditions and their combined effect on our business, are material factors we consider when determining our strategic priorities, objectives and expectations for our business. Assumptions about our integration plan, the efficiency and duration of integration and the alignment of organizational responsibilities were material factors we considered in estimating pre-tax cost synergies and integration costs. Assumptions about BMO’s current and expected financial performance (including balance sheet, income statement and regulatory capital figures), expected cost and revenue synergies (and timing to achieve) relating to the Bank of the West acquisition, and current and future foreign exchange rates, interest rates and shares outstanding were material factors considered in estimating adjusted EPS accretion.

In determining our expectations for economic growth, we primarily consider historical economic data, past relationships between economic and financial variables, changes in government policies, and the risks to the domestic and global economy.

BMO Financial Group Second Quarter Report 2023 7

Economic Developments and Outlook ^(1)^

Canada’s economy is expected to post modest 1.0% growth in 2023 after expanding 3.4% in 2022. The economy has slowed as a result of high inflation, rising interest rates and weaker global demand, and will likely contract slightly in the second and third quarters of 2023. Positive growth should resume later in the current year amid support from high levels of household savings and a moderation of inflation. The housing market appears to be stabilizing as a result of recent steadier interest rates, though activity will likely remain restrained until mortgage rates decline and affordability improves. The expected mild economic downturn is projected to raise the unemployment rate from a near half-century low of 5.0% in April 2023 to 5.8% in December 2023, which will help to reduce wage and price pressures. The annual growth in the consumer price index has declined from four-decade highs of 8.1% last summer, to 4.4% in April 2023 and is projected to moderate further to around 3% at year-end. After raising the overnight lending rate by 425 basis points since March 2022, the Bank of Canada has held rates steady since January 2023 and is expected to remain on hold for the rest of the year, before returning rates to less restrictive levels starting early in 2024. Industry-wide growth in residential mortgage balances has decelerated from almost 11% in early 2022 to below 6% in February 2023 and is expected to moderate further to a low single-digit pace in 2023, as a result of depressed housing market activity. Growth in consumer credit balances (excluding mortgages) has been restrained at less than a 4% year-over-year rate in recent months due to the higher interest rate environment and elevated household savings, and is anticipated to rise only modestly in the current year as households curtail spending. Following strong growth in 2022, the rate of non-financial corporate credit growth is projected to decelerate sharply in response to higher interest rates, recession concerns, and elevated cash balances.

After slowing to a 2.1% growth rate in 2022, the U.S. economy is expected to contract slightly in the spring and summer of 2023, and register modest 1.0% growth in 2023. Rising interest rates, high inflation, and a high-valued currency have restrained activity, though household spending remains supported by elevated savings and rising employment. In addition, recent stress in the U.S. banking system is expected to lead to tighter lending conditions, thereby slowing credit growth, investment and overall spending. The year-long downturn in the housing market appears to be levelling off, though activity is expected to remain depressed for the remainder of the current year. The expected economic contraction will likely raise the unemployment rate from 3.4% in April 2023 to 4.8% in December 2023, still low by historical standards. Lower energy prices and improved global supply chains have reduced annual growth in the consumer price index from 9.1% in the summer of 2022 to 4.9% in April 2023, and the rate is anticipated to decline further to approximately 3% at year-end. After raising its policy rate by 500 basis points since March 2022, the Federal Reserve has signalled a probable pause in the tightening cycle. We anticipate no further rate increases this year, before the central bank begins to loosen policy in early 2024. Earlier strong growth in industry-wide residential mortgage balances has started to decelerate as a result of weak housing market activity. Consumer credit balance growth is expected to weaken in 2023 as a result of elevated interest rates, higher unemployment and slower consumer spending. Non-financial corporate credit growth strengthened last year as companies took advantage of previously low borrowing costs, but growth is projected to decelerate quickly in response to higher interest rates, a weaker economy, and the drawing down of large deposit balances.

The economic outlook is subject to several risks that could lead to a more severe contraction of the North American economy. These include the persistence of high inflation leading to significant further increases in interest rates, continued stress in the U.S. regional banking sector, an escalation of the conflict in Ukraine, and an increase in geopolitical tensions between the United States and China. In addition, the U.S. Congress will need to raise the debt ceiling soon to avoid a potential default that could lead to financial market turbulence and a much weaker economy.

This Economic Developments and Outlook section contains forward-looking statements. Please see the Caution Regarding Forward-Looking Statements.

(1) Adjusted results exclude certain items from reported results and are used to calculate our adjusted measures as presented<br>in the above table. Management assesses performance on a reported basis and an adjusted basis, and considers both to be useful. Revenue, net of CCPB, as well as reported ratios calculated net of CCPB and adjusted results, measures and ratios in this<br>table are non-GAAP. For further information, refer to the Non-GAAP and Other Financial Measures section, and for details on the composition of non-GAAP amounts, measures and ratios, as well as supplementary financial measures, refer to the Glossary of Financial Terms.
(2) We present revenue, efficiency ratio and operating leverage on a basis that is net of CCPB, which reduces the variability<br>in insurance revenue from changes in the fair value that are largely offset by changes in the fair value of policy benefit liabilities, the impact of which is reflected in CCPB. For further information, refer to the Insurance Claims, Commissions and<br>Changes in Policy Benefits section.

Non-GAAP and Other Financial Measures

Results and measures in this document are presented on a GAAP basis. Unless otherwise indicated, all amounts are in Canadian dollars and have been derived from our audited annual consolidated financial statements prepared in accordance with International Financial Reporting Standards (IFRS). References to GAAP mean IFRS. We use a number of financial measures to assess our performance, as well as the performance of our operating segments, including amounts, measures and ratios that are presented on a non-GAAP basis, as described below. We believe that these non-GAAP amounts, measures and ratios, read together with our GAAP results, provide readers with a better understanding of how management assesses results.

Non-GAAP amounts, measures and ratios do not have standardized meanings under GAAP. They are unlikely to be comparable to similar measures presented by other companies and should not be viewed in isolation from, or as a substitute for, GAAP results.

For further information regarding the composition of non-GAAP and other financial measures, including supplementary financial measures, refer to the Glossary of Financial Terms.

Our non-GAAP measures broadly fall into the following categories:

Adjusted measures and ratios

Management considers both reported and adjusted results and measures to be useful in assessing underlying ongoing business performance. Adjusted results and measures remove certain specified items from revenue, non-interest expense, provision for credit losses and income taxes, as detailed in the following table. Adjusted results and measures presented in this document are non-GAAP. Presenting results on both a reported basis and an adjusted basis permits readers to assess the impact of certain items on results for the periods presented, and to better assess results excluding those items that may not be reflective of ongoing business performance. As such, the presentation may facilitate readers’ analysis of trends. Except as otherwise noted, management’s discussion of changes in reported results in this document applies equally to changes in the corresponding adjusted results.

Measures net of insurance claims, commissions and changes inpolicy benefit liabilities (CCPB)

We also present reported and adjusted revenue on a basis that is net of insurance claims, commissions and changes in policy benefit liabilities (CCPB), and our efficiency ratio and operating leverage are calculated on a similar basis. Measures and ratios presented on a basis net of CCPB are non-GAAP. Insurance revenue can experience variability arising from fluctuations in the fair value of insurance assets, caused by movements in interest rates and equity markets. The investments that support policy benefit liabilities are predominantly fixed income assets recorded at fair value, with changes in fair value recorded in insurance revenue in the Consolidated Statement of Income. These fair value changes are largely offset by changes in the fair value of policy benefit liabilities, the impact of which is reflected in CCPB. The presentation and discussion of revenue, efficiency ratios and operating leverage on a net basis reduces this variability, which allows for a better assessment of operating results. For more information refer to the Insurance Claims, Commissions and Changes in Policy Benefit Liabilities section.

Tangible common equity and return on tangible common equity

Tangible common equity is calculated as common shareholders’ equity less goodwill and acquisition-related intangible assets, net of related deferred tax liabilities. Return on tangible common equity is commonly used in the North American banking industry and is meaningful because it measures the performance of businesses consistently, whether they were acquired or developed organically.

14 BMO Financial Group Second Quarter Report 2023

Foreign Exchange

The Canadian dollar equivalents of BMO’s U.S. segment results that are denominated in U.S. dollars increased relative to both the second quarter of 2022 and the first quarter of 2023, due to changes in the Canadian/U.S. dollar exchange rate. The exchange rate for YTD-2023 increased relative to YTD-2022. The table below indicates the relevant average Canadian/U.S. dollar exchange rates and the impact of changes in those rates on BMO’s U.S. segment results. References in this document to the impact of the U.S. dollar do not include U.S. dollar-denominated amounts recorded outside of BMO’s U.S. segment.

Economically, our U.S. dollar income stream was not hedged against the risk of changes in foreign exchange rates during 2023 and 2022. Changes in exchange rates will affect future results measured in Canadian dollars, and the impact on those results is a function of the periods in which revenue, expenses, provisions for (recoveries of) credit losses and income taxes arise.

Refer to the Enterprise-Wide Capital Management section of BMO’s 2022 Annual Report for a discussion of the impact that changes in foreign exchange rates can have on BMO’s capital position.

Net income increased in U.S. P&C due to the inclusion of Bank of the West and the impact of the stronger U.S. dollar, and decreased across all other operating groups. On a reported basis, Corporate Services recorded a net loss compared with net income in the prior year, and on an adjusted basis, Corporate Services recorded a higher net loss.

Reported net income increased from the prior quarter, primarily due to the impact of the adjusting items noted above, and adjusted net income decreased 2%, with higher revenue more than offset by higher expenses and provisions for credit losses. Net income increased in U.S. P&C due to the inclusion of Bank of the West, and decreased in BMO Capital Markets and Canadian P&C. BMO Wealth Management net income was relatively unchanged. On a reported basis, Corporate Services recorded a lower net loss compared with the prior quarter, primarily due to the items noted above, and on an adjusted basis, the net loss was relatively unchanged.

Reported net income was $1,306 million, compared with $7,689 million in the prior year, and adjusted net income was $4,488 million, a decrease of $283 million or 6%. Reported EPS was $1.62, a decrease of $9.95 from the prior year, and adjusted EPS was $6.15, a decrease of $0.97.

Reported net income decreased from the prior year, primarily due to lower revenue from the fair value management actions, higher acquisition and integration costs, the initial provision for credit losses on the purchased Bank of the West performing loan portfolio, and the tax expense related to certain tax measures enacted by the Canadian government, partially offset by the impact of divestiture costs in the prior year. Net income increased in our U.S. P&C business and decreased in BMO Capital Markets, Canadian P&C and BMO Wealth Management. On a reported basis, Corporate Services recorded net loss compared with a net income in the prior year, primarily due to the items noted above, and on an adjusted basis, Corporate Services recorded a higher net loss.

Revenue

Q2 2023 vs. Q2 2022

Reported revenue was $8,440 million, compared with $9,318 million in the prior year. Reported revenue, net of CCPB, was $7,849 million compared with $10,126 million in the prior year, a decrease of $2,277 million or 22%, and adjusted net revenue was $7,856 million compared with $6,563 million, an increase of $1,293 million or 20%. Adjusted net revenue in the current quarter excluded interest expense related to a legal provision. The prior year excluded revenue related to fair value management actions, as well as the impact of divestitures. The impact of the stronger U.S. dollar increased net revenue by 3% on both a reported and an adjusted basis. Bank of the West contributed $1,072 million to revenue.

The decrease in reported results primarily reflected the items noted above. On an adjusted basis, revenue increased in U.S. P&C, primarily due to the inclusion of Bank of the West and higher net interest income reflecting higher margins and loan balances, partially offset by lower non-interest income, in Canadian P&C due to higher net interest income reflecting balance growth and higher margins, partially offset by lower non-interest income, and in BMO Wealth Management reflecting the inclusion of Bank of the West, partially offset by the impact of weaker global markets. Revenue in BMO Capital Markets was relatively unchanged from the prior year. Revenue in Corporate Services decreased on both a reported and an adjusted basis.

Reported net interest income was $4,814 million, an increase of $912 million or 23%, and adjusted net interest income was $4,821 million, an increase of $1,041 million or 28%. Adjusted results excluded interest expense of $7 million related to the legal provision in the current quarter and revenue of $122 million from the impact of fair value management actions in the prior year. Adjusted non-trading net interest income was $4,579 million, an increase of $1,206 million or 36%, due to the inclusion of Bank of the West and associated net mark accretion, and increases in our P&C businesses due to balance growth and higher net interest margins, partially offset by lower net interest income in Corporate Services and the impact of risk transfer transactions. Trading-related net interest income was $242 million, a decrease of $165 million that was partially offset in trading non-interest revenue.

Average earning assets were $1,165.2 billion, an increase of $215.9 billion or 23%, primarily due to the inclusion of Bank of the West, loan growth, the impact of the stronger U.S. dollar and higher liquidity requirements in Corporate Services.

BMO’s overall reported net interest margin of 1.69% was unchanged from the prior year, and adjusted net interest margin increased 7 basis points. Adjusted net interest margin excluding trading-related net interest income and earning assets was 1.88%, an increase of 15 basis points, due to the impact of Bank of the West and associated net mark accretion, and higher margins in our P&C businesses, partially offset by lower net interest income and higher low-yielding assets in Corporate Services, and the impact of risk transfer transactions.

Reported non-interest revenue was $3,626 million, a decrease of $1,790 million or 33% from $5,416 million in the prior year, and reported non-interest revenue, net of CCPB, was $3,035 million, a decrease of $3,189 million or 51% from $6,224 million. Results reflected the impact of fair value

16 BMO Financial Group Second Quarter Report 2023

management actions noted above. Adjusted non-interest revenue, net of CCPB, was $3,035 million, an increase of $252 million or 9% from the prior year, primarily due to higher trading revenue, deposit and payment service and lending fee revenue.

Gross insurance revenue was $726 million, compared with a loss of $673 million in the prior year, primarily due to changes in the fair value of investments. Insurance revenue can experience variability arising from fluctuations in the fair value of insurance assets caused by movements in interest rates and equity markets. The investments that support policy benefit liabilities are predominantly fixed income and equity assets recorded at fair value, with changes in fair value recorded in insurance revenue in the Consolidated Statement of Income. The impact of these fair value changes was largely offset by changes in policy benefit liabilities, which are discussed in the Insurance Claims, Commissions and Changes in Policy Benefit Liabilities section.

Q2 2023 vs. Q1 2023

Reported revenue increased $1,970 million or 30% from $6,470 million in the prior quarter. Reported revenue, net of CCPB increased $2,572 million or 49% due to the impact of fair value management actions in the prior quarter. Adjusted net revenue increased $562 million or 8%. Results were impacted by three fewer days in the current quarter. Reported net revenue increased in U.S. P&C and BMO Wealth Management, primarily due to the inclusion of Bank of the West. Revenue decreased in Canadian P&C due to lower net interest income and non-interest revenue, and in BMO Capital Markets, primarily due to lower revenue in Global Markets. Revenue in Corporate Services increased on a reported basis and decreased on an adjusted basis.

Reported net interest income increased $793 million or 20% from the prior quarter, primarily due to fair value management actions in the prior quarter. Adjusted net interest income increased $411 million or 9%, due to the inclusion of Bank of the West and associated net mark accretion, partially offset by lower net interest income in Corporate Services and three fewer days in the current quarter. Trading-related net interest income decreased $43 million or 15% from the prior quarter.

Average earning assets increased $86.2 billion or 8%, primarily due to the inclusion of Bank of the West, partially offset by a decrease in cash equivalent balances.

BMO’s overall reported net interest margin increased 21 basis points, primarily due to the inclusion of Bank of the West and associated net mark accretion, and the adjusting items noted above, and adjusted net interest margin increased 8 basis points. Adjusted net interest margin excluding trading-related net interest income and earning assets increased 9 basis points, primarily due to the impact of Bank of the West, partially offset by lower net interest income in Corporate Services.

Reported non-interest revenue increased $1,177 million from the prior quarter, and reported non-interest revenue, net of CCPB, increased $1,779 million, primarily reflecting the impact of the adjusting items noted above. Adjusted non-interest revenue, net of CCPB, increased $151 million or 5% from the prior quarter, primarily due to higher fee revenue from deposit and payment services, underwriting and advisory services, card fee revenue, and investment management and custodial fee revenue, partially offset by lower securities gains, other than trading.

Gross insurance revenue decreased $605 million from the prior quarter, primarily due to changes in the fair value of investments. The decrease in insurance revenue was largely offset by changes in CCPB, as discussed in the Insurance Claims, Commissions and Changes in Policy Benefit Liabilities section.

Q2 YTD 2023 vs. Q2 YTD 2022

Total reported revenue was $14,910 million, compared with $17,041 million in the prior year, and reported revenue, net of CCPB, was $13,126 million, compared with $17,768 million.

The decrease in reported revenue reflected the impact of fair value management actions noted above. On an adjusted basis, revenue increased in U.S. P&C, primarily due to the inclusion of Bank of the West and higher net interest income reflecting higher margins and loan balances, partially offset by lower non-interest revenue, and in Canadian P&C due to higher net interest income reflecting balance growth and higher margins, partially offset by lower non-interest income. Revenue increased in BMO Wealth Management, primarily reflecting the inclusion of Bank of the West in Wealth and Asset Management, partially offset by the impact of weaker global markets, and higher Insurance revenue. Revenue decreased in BMO Capital Markets. Revenue in Corporate Services decreased on both a reported and an adjusted basis from the prior year.

Reported net interest income was $8,835 million, an increase of $914 million or 12%, and adjusted net interest income was $9,231 million, an increase of $1,477 million or 19%. Adjusted results excluded interest expense of $13 million related to the legal provision and a loss of $383 million related to the fair value management actions in the current year. Adjusted non-trading net interest income was $8,704 million, an increase of $1,921 million or 28%, with increases across all operating businesses and reflected strong balance growth, higher net interest margins and the inclusion of Bank of the West and associated net mark accretion, partially offset by the impact of risk transfer transactions and lower net interest income in Corporate Services. Trading-related net interest income was $527 million, a decrease of $444 million that was partially offset in trading non-interest revenue.

Average earning assets were $1,121.4 billion, an increase of $160.2 billion or 17%, primarily due to loan growth, the inclusion of Bank of the West, the impact of the stronger U.S. dollar and higher liquidity requirements in Corporate Services.

BMO’s overall reported net interest margin of 1.59% decreased 7 basis points from the prior year, primarily due to the impact of fair value management actions and lower trading-related net interest income. Adjusted net interest margin increased 3 basis points from the prior year. Adjusted net interest margin excluding trading-related net interest income and earning assets was 1.83%, an increase of 13 basis points, primarily due to higher margins in our P&C businesses and the impact of Bank of the West and associated net mark accretion, partially offset by lower net interest income and higher low-yielding assets in Corporate Services and the impact of risk transfer transactions.

Reported non-interest revenue was $6,075 million, a decrease of $3,045 million or 33% from $9,120 million in the prior year, and reported non-interest revenue, net of CCPB, was $4,291 million, a decrease of $5,556 million or 56% from $9,847 million. Results reflected the impact of the fair

value management actions noted above. Adjusted non-interest revenue, net of CCPB, was $5,919 million, unchanged from the prior year, as higher trading revenue and the impact of Bank of the West was offset by lower underwriting and advisory revenue and lower securities gains, other than trading.

Net interest income and non-interest revenue are detailed in the unaudited interim consolidated financial statements.

Gross insurance revenue was $2,057 million, compared with a loss of $481 million in the prior year, primarily due to changes in the fair value of investments.

Total Provision for Credit Losses

Q2 2023 vs. Q22022

Total reported provision for credit losses was $1,023 million and total adjusted provision for credit losses was $318 million, compared with a reported and adjusted provision of $50 million in the prior year. The total provision for credit losses as a percentage of average net loans and acceptances ratio was 65 basis points on a reported basis and 20 basis points on an adjusted basis, compared with 4 basis points on both a reported and adjusted basis in the prior year. Adjusted provision for credit losses excluded the initial provision on the purchased Bank of the West performing loan portfolio of $705 million.

The provision for credit losses on impaired loans was $243 million, an increase of $123 million from the prior year, primarily due to higher provisions in Personal and Business Banking in our P&C businesses. The provision for credit losses on impaired loans as a percentage of average net loans and acceptances ratio was 16 basis points, compared with 10 basis points in the prior year.

The provision for credit losses on performing loans was $780 million on a reported basis and $75 million on an adjusted basis, compared with a reported and adjusted recovery of $70 million in the prior year. The $780 million provision for credit losses on performing loans in the current quarter included the initial provision on the purchased Bank of the West performing loan portfolio noted above. On an adjusted basis, the $75 million provision for credit losses on performing loans in the current quarter reflected portfolio credit migration, model changes and economic uncertainty, partially offset by a modest improvement in macro-economic variables, including the continued benefit from risk transfer transactions. The $70 million recovery of credit losses in the prior year largely reflected reduced uncertainty, as a result of the improving pandemic environment, portfolio credit improvement and model changes, partially offset by a deteriorating economic outlook, increased adverse scenario weight and portfolio growth.

Q2 2023 vs. Q1 2023

Total reported provision increased $806 million from the prior quarter, and adjusted provision increased $101 million. The total provision for credit losses as a percentage of average net loans and acceptances ratio was 65 basis points on a reported basis and 20 basis points on an adjusted basis, compared with 15 basis points on both a reported and adjusted basis in the prior quarter. Adjusted provision excludes the item noted above.

18 BMO Financial Group Second Quarter Report 2023

The provision for credit losses on impaired loans increased $47 million from the prior quarter, primarily due to higher provisions in Personal and Business Banking partially offset by lower provisions in Commercial Banking in our P&C businesses. The provision for credit losses on impaired loans as a percentage of average net loans and acceptances ratio was 16 basis points, compared with 14 basis points in the prior quarter.

The provision for credit losses on performing loans was $780 million on a reported basis and $75 million on an adjusted basis, compared with a reported and adjusted provision of $21 million in the prior quarter. The $780 million provision for credit losses on performing loans in the current quarter included the initial provision on the purchased Bank of the West performing loan portfolio noted above. On an adjusted basis, the $75 million provision for credit losses on performing loans in the current quarter reflected the items noted above. The $21 million provision for credit losses on performing loans in the prior quarter reflected economic uncertainty and growth in certain portfolios, largely offset by portfolio credit improvement, and benefits from risk transfer transactions.

Q2 YTD 2023 vs. Q2 YTD 2022

Total reported provision for credit losses was $1,240 million and total adjusted provision for credit losses was $535 million, compared with a reported and adjusted recovery of the provision for credit losses of $49 million in the prior year. Total provision for credit losses ratio was 42 basis points on a reported basis and 18 basis points on an adjusted basis, compared with a total recovery of provision of credit losses ratio of 2 basis points on both a reported and adjusted basis in the prior year. On an adjusted basis, the provision for credit losses excluded the item noted above.

The provision for credit losses on impaired loans was $439 million, an increase of $233 million from the prior year, primarily due to higher provisions in Personal and Business Banking in our P&C businesses. The provision for credit losses on impaired loans ratio was 15 basis points, compared with 8 basis points in the prior year.

The provision for credit losses on performing loans was $801 million on a reported basis and $96 million on an adjusted basis, compared with a reported and adjusted recovery of $255 million in the prior year. The $801 million provision for credit losses on performing loans in the current year included the initial provision noted above. On an adjusted basis, the $96 million provision for credit losses on performing loans in the current year largely reflected economic uncertainty, portfolio credit migration and growth in certain portfolios, partially offset by a modest improvement in macro-economic variables and benefits from risk transfer transactions. The recovery in the prior year largely reflected reduced uncertainty as a result of the improving pandemic environment and portfolio credit improvement, partially offset by a deteriorating economic outlook, adoption of a higher adverse scenario weight and portfolio growth.

Insurance Claims, Commissions and Changes in Policy Benefit Liabilities

Insurance claims, commissions and changes in policy benefit liabilities (CCPB) in the current quarter were $591 million, an increase of $1,399 million from the prior year. Results increased, largely due to changes in the fair value of policy benefit liabilities. CCPB decreased $602 million from the prior quarter, due to changes in the fair value of policy benefit liabilities. These changes were largely offset in insurance revenue.

Non-Interest Expense

Q2 2023 vs. Q2 2022

Reported non-interest expense was $5,573 million, compared with $3,713 million in the prior year, and adjusted non-interest expense was $4,731 million, an increase of $1,081 million or 30%. Bank of the West contributed $1,581 million to non-interest expense on a reported basis and $755 million on an adjusted basis. The impact of the stronger U.S. dollar increased non-interest expense by approximately 4% on a reported basis and 3% on an adjusted basis. Adjusted non-interest expense excluded the impact of acquisition and integration costs and amortization of acquisition-related intangible assets in both the current and prior year, and divestiture costs in the prior year.

The increase in reported expenses reflected higher acquisition and integration costs and amortization of acquisition-related intangibles. Reported and adjusted expenses increased due to the impact of Bank of the West, as well as increases in underlying expenses across most categories, including the impact of the prior year investments in sales force and technology, as well as higher legal provisions.

The reported gross efficiency ratio was 66.0%, compared with 39.9% in the prior year. On a net revenue basis^(1)^, the reported efficiency ratio was 71.0%, compared with 36.7% in the prior year, and the adjusted efficiency ratio was 60.2%, compared with 55.6% in the prior year. Reported gross operating leverage was negative 59.4%. On a net revenue basis, reported operating leverage was negative 72.5% and adjusted net operating leverage was negative 9.8%.

(1) This ratio is calculated using net revenue and non-interest expense. For further<br>discussion of revenue, refer to the Revenue section.

Q2 2023 vs. Q1 2023

Reported non-interest expense increased $1,152 million or 26% from the prior quarter, and adjusted non-interest expense increased $559 million or 13%. Adjusted results excluded the items noted above.

The increase in reported non-interest expense reflected higher acquisition and integration costs and amortization of acquisition-related intangible assets. In addition, reported and adjusted non-interest expense reflected the impact of Bank of the West, partially offset by lower underlying expenses, largely driven by stock-based compensation that is expensed in the first quarter of each year and the seasonality of benefits, as well as the impact of three fewer days in the current quarter.

The reported gross efficiency ratio was 66.0%, compared with 68.3% in the prior quarter. On a net revenue basis, the reported efficiency ratio was 71.0%, compared with 83.8% in the prior quarter, and the adjusted efficiency ratio was 60.2%, compared with 57.2% in the prior quarter. On a net revenue basis, reported operating leverage ratio was negative 72.5%, compared with negative 46.0% in the prior quarter and adjusted net operating leverage was negative 9.8%, compared with negative 6.4%.

20 BMO Financial Group Second Quarter Report 2023

Q2 YTD 2023 vs. Q2 YTD 2022

Reported non-interest expense was $9,994 million, an increase of $2,435 million or 32% from the prior year, and adjusted non-interest expense was $8,903 million, an increase of $1,424 million or 19%. The impact of the stronger U.S. dollar increased non-interest expense by approximately 3% on both a reported and an adjusted basis. Adjusted results excluded the items noted above.

The increase in reported non-interest expense primarily reflected higher acquisition and integration costs and amortization of acquisition-related intangible assets. Reported and adjusted non-interest expense increased due to the inclusion of Bank of the West, as well as reflected higher underlying expenses across most categories, including the impact of the prior year investments in sales force and technology, as well as higher legal provisions.

The reported efficiency ratio was 67.0%, compared with 44.4% in the prior year, and was 76.1% on a net revenue basis, compared with 42.5% in the prior year. The adjusted efficiency ratio on a net revenue basis was 58.8%, compared with 54.7% in the prior year.

Non-interest expense is detailed in the unaudited interim consolidated financial statements.

For further information on non-GAAP amounts, measures and ratios in this Non-Interest Expense section, refer to the Non-GAAP and Other Financial Measures section.

Provision for Income Taxes

The provision for income taxes was $194 million, a decrease of $1,413 million from the second quarter of 2022, and a decrease of $198 million from the first quarter of 2023. The effective tax rate for the current quarter was 15.5%, compared with 25.2% in the second quarter of 2022, and 61.4% in the first quarter of 2023.

The adjusted provision for income taxes was $591 million, a decrease of $85 million from the second quarter of 2022, and a decrease of $42 million from the first quarter of 2023. The adjusted effective tax rate was 21.1% in the current quarter, compared with 23.6% in the second quarter of 2022, and 21.8% in the first quarter of 2023. The change in the reported effective tax rate in the current quarter relative to the second quarter of 2022 and the first quarter of 2023 was primarily due to the impact of higher pre-tax earnings in the prior year and the impact of the one-time tax expense of $371 million in the prior quarter related to the Canada Recovery Dividend, and the prorated fiscal 2022 impact of the 1.5% increase in tax rate, net of a related revaluation of our net deferred tax asset. The change in the adjusted effective tax rate in the current quarter relative to the second quarter of 2022 and the first quarter of 2023 was primarily due to earnings mix.

Additional information regarding accounting for income taxes is included in Note 10 of the unaudited interim consolidated financial statements.

Total assets were $1,250.9 billion as at April 30, 2023, an increase of $111.7 billion from October 31, 2022. The weaker U.S. dollar decreased assets by $3.3 billion, excluding the impact on derivative financial assets.

Cash and cash equivalents and interest bearing deposits with banks decreased $19.4 billion, primarily due to lower balances held with central banks following the completion of the Bank of the West acquisition on February 1, 2023, as well as lower balances in BMO Capital Markets.

Securities increased $42.7 billion, primarily due to the inclusion of Bank of the West and client activity in BMO Capital Markets, partially offset by the impact of the weaker U.S. dollar.

Securities borrowed or purchased under resale agreements increased $5.4 billion due to client activity in BMO Capital Markets.

Net loans and acceptances increased $80.8 billion. Bank of the West contributed $78.5 billion to net loans and acceptances as at April 30, 2023. Business and government loans and acceptances increased $24.5 billion, reflecting the impact of Bank of the West and growth in Canadian P&C, BMO Capital Markets and BMO Wealth Management, partially offset by lower source currency balances in U.S. P&C and the impact of the weaker U.S. dollar. Consumer instalment and other personal loans increased $18.3 billion due to the inclusion of Bank of the West, partially offset by lower balances in our P&C businesses. Non-residential mortgages increased $19.5 billion, primarily due to the inclusion of Bank of the West. Residential mortgages increased $17.9 billion, primarily due to the impact of Bank of the West and growth in our P&C businesses. Credit card balances increased $1.4 billion due to growth in Canadian P&C and the inclusion of Bank of the West.

Derivative financial assets decreased $16.2 billion, primarily due to a decrease in the value of client-driven trading derivatives in BMO Capital Markets, with decreases in the fair value of foreign exchange, commodities, interest rate and equity contracts.

Other assets increased $18.5 billion due to the inclusion of Bank of the West, primarily driven by goodwill and intangible assets.

Liabilities increased $106.6 billion from October 31, 2022. The weaker U.S. dollar decreased liabilities by $3.2 billion, excluding the impact on derivative financial liabilities.

Deposits increased $106.0 billion. Bank of the West contributed $87.0 billion to deposits as at April 30, 2023, including $84.5 billion in customer deposits. The increase in underlying deposit balances were driven by higher wholesale funding, primarily to fund Global Markets client activity and to meet structural funding needs, and growth in Canadian P&C customer deposits, partially offset by lower source currency customer deposits in U.S. P&C, BMO Capital Markets and BMO Wealth Management, as well as the impact of the weaker U.S. dollar.

Derivative financial liabilities decreased $18.2 billion, largely due to a decrease in the value of client-driven trading derivatives in BMO Capital Markets reflecting decreases in the fair value of foreign exchange, interest rate, equity and commodities contracts.

Securities lent or sold under repurchase agreements increased $1.2 billion due to client activity in BMO Capital Markets, partially offset by the impact of the weaker U.S. dollar.

Other liabilities increased $17.6 billion, driven by higher Federal Home Loan Bank borrowings, including the impact of Bank of the West, an increase in securities sold but not yet purchased due to client activity in BMO Capital Markets, and higher insurance-related liabilities, partially offset by lower acceptances as a result of lower levels of acceptances being issued into the market.

Subordinated debt was relatively unchanged.

Equity increased $5.0 billion from October 31, 2022, primarily due to common and preferred share issuances and higher accumulated other comprehensive income, partially offset by a decrease in retained earnings. Common shares increased $4.3 billion, as a result of share issuances during the first quarter of 2023, as well as shares issued under the dividend reinvestment and share purchase plan. Preferred shares and other equity instruments increased $0.7 billion and reflected an issuance in the first quarter of 2023. Accumulated other comprehensive income increased $1.0 billion, as gains on cash flow hedges due to lower medium to long-term interest rates were partially offset by losses on remeasurement of own credit risk on financial liabilities designated at fair value. Retained earnings decreased $974 million, as a result of dividends and distributions on other equity instruments, partially offset by net income earned in the current year.

Contractual obligations by year of maturity are outlined in the Contractual Maturities of Assets and Liabilities and Off-Balance Sheet Commitments table in the Risk Management section.

22 BMO Financial Group Second Quarter Report 2023

Capital Management

BMO continues to manage its capital within the framework described in the Enterprise-Wide Capital Management section of BMO’s 2022 Annual Report.

Second Quarter 2023 Regulatory Capital Review

BMO’s Common Equity Tier 1 (CET1) Ratio was 12.2% as at April 30, 2023, a decrease from 18.2% at the end of the first quarter of 2023, primarily due to the acquisition of Bank of the West.

CET1 Capital was $51.4 billion as at April 30, 2023, a decrease from $63.1 billion as at January 31, 2023, primarily due to a higher capital deduction for goodwill and intangible assets related to Bank of the West, partially offset by higher accumulated other comprehensive income, primarily due to foreign exchange movements, internal capital generation and common shares issued under the shareholder dividend reinvestment and share purchase plan (DRIP). For more information on the acquisition of Bank of the West, refer to the Significant Events section and Note 12 of the unaudited interim consolidated financial statements.

In calculating regulatory capital ratios, there is a requirement to increase total risk-weighted assets (RWA) when a capital floor amount calculated under the standardized approach is higher than a similar calculation using more risk-sensitive internal modelled approaches, where applicable. The capital floor was not operative as at April 30, 2023, compared with a floor adjustment of $10.8 billion at January 31, 2023.

RWA were $420.0 billion as at April 30, 2023, an increase from $347.5 billion as at January 31, 2023. RWA increased primarily due to the inclusion of Bank of the West and foreign exchange movements, partially offset by lower RWA as the result of the elimination of the capital floor adjustment and the implementation of the Basel III Reforms. Changes under the Basel III Reforms included revised rules for credit risk and operational risk, effective February 1, 2023, which reduced RWA by approximately $8.2 billion.

The bank’s Tier 1 and Total Capital Ratios were 13.9% and 16.0%, respectively, as at April 30, 2023, compared with 20.1% and 22.6%, respectively, as at January 31, 2023, primarily due to the same factors impacting the CET1 Ratio.

The impact of foreign exchange movements on capital ratios was largely offset. BMO’s investments in foreign operations are primarily denominated in U.S. dollars, and the foreign exchange impact of U.S.-dollar-denominated RWA and capital deductions may result in variability in the bank’s capital ratios. We may manage the impact of foreign exchange movements on our capital ratios, and we did so during the current quarter. Any such activities could also impact our book value and return on equity.

Our Leverage Ratio was 4.2% as at April 30, 2023, a decrease from 5.9% at the end of the first quarter of 2023, primarily due to the acquisition of Bank of the West.

The bank’s risk-based Total Loss Absorbing Capacity (TLAC) Ratio and TLAC Leverage Ratio were 27.0% and 8.3%, respectively, as at April 30, 2023, compared with 37.2% and 10.9%, respectively, as at January 31, 2023.

Regulatory Capital Developments

On December 8, 2022, the Office of the Superintendent of Financial Institutions (OSFI) announced that the Domestic Stability Buffer (DSB) level will be set at 3% of total RWA as of February 1, 2023. In addition, OSFI increased the DSB’s range from 0% to 2.5%, to 0% to 4%.

The domestic implementation of Basel III Reforms related to capital, leverage, liquidity and disclosure requirements were effective in the second quarter of 2023. Capital changes under these reforms include revised rules for credit risk and operational risk. Effective February 1, 2023, D-SIBs were required to meet a 0.5% buffer requirement for the Leverage and TLAC Leverage Ratios in addition to the minimum requirements. Revisions related to market risk and credit valuation adjustment risk will become effective in the first quarter of 2024.

Refer to the Enterprise-Wide Capital Management section of BMO’s 2022 Annual Report for a more detailed discussion of regulatory developments.

Regulatory Capital, Leverage and TLAC

Regulatory capital requirements for BMO are determined in accordance with OSFI’s CAR Guideline and the Leverage Requirements (LR) Guideline, which are based on the standards developed by the Basel Committee on Banking Supervision. TLAC requirements are determined in accordance with OSFI’s TLAC Guideline. For more information see the Enterprise-Wide Capital Management section of BMO’s 2022 Annual Report.

OSFI’s capital, leverage and TLAC requirements are summarized in the following table.

(% of risk-weighted assets or leverage exposures) Minimum capital,<br>leverage and TLAC<br>requirements Total Pillar 1 Capital<br>Buffer (1) Tier 1 Capital<br><br><br>Buffer (2) Domestic Stability<br>Buffer^^(3) Minimum capital,<br>leverage and TLAC<br>requirements including<br>capital buffers BMO capital, leverage<br>and TLAC ratios as at<br>April 30, 2023

Leverage Ratio 3.0% na 0.5% na 3.5% 4.2%
TLAC Leverage Ratio 6.75% na 0.5% na 7.25% 8.3%
(1) The minimum 4.5% CET1 Ratio requirement is augmented by the 3.5% Total Pillar 1 Capital Buffers, which can absorb losses<br>during periods of stress. The Pillar 1 Capital Buffers, which will be met with CET1 Capital, include a 2.5% Capital Conservation Buffer, a 1.0% Common Equity Surcharge for domestic systemically important banks<br>(D-SIBs) and a Countercyclical Buffer, as prescribed by OSFI (immaterial for the second quarter of 2023). If a bank’s capital ratios fall within the range of this combined buffer, restrictions on<br>discretionary distributions of earnings (such as dividends, share repurchases and discretionary compensation) would ensue, with the degree of such restrictions varying according to the position of the bank’s ratios within the buffer range.<br>
--- ---
(2) Effective February 1, 2023, D-SIBs are required to meet a 0.5% Tier 1 capital<br>buffer requirement for the Leverage and TLAC Leverage Ratios.
--- ---
(3) OSFI requires all D-SIBs to hold a Domestic Stability Buffer (DSB) against Pillar<br>2 risks associated with systemic vulnerabilities. The DSB was set at 3.0% as at April 30, 2023. OSFI increased the DSB range from 0% to 2.5%, to 0% to 4%, and increased the DSB to 3.0% effective February 1, 2023. Breaches of the DSB do not<br>result in a bank being subject to automatic constraints on capital distributions. Banks may be required to hold additional buffers that are applicable to capital, leverage and TLAC ratios.

OSFI’s CAR Guideline includes non-viability contingent capital (NVCC) provisions, which require the conversion of Additional Tier 1 and Tier 2 capital instruments into common shares if OSFI announces that a bank is, or is about to become, non-viable, or if the federal or a provincial government in Canada publicly announces that the bank has accepted, or has agreed to accept, a capital injection or equivalent support to avoid non-viability. Pursuant to the principles set out in the CAR Guideline, the conversion to common shares respects the hierarchy of claims in liquidation ensuring that Additional Tier 1 and Tier 2 instrument holders are entitled to a more favourable economic outcome than existing common shareholders.

If an NVCC trigger event were to occur, our NVCC instruments would be converted into BMO common shares pursuant to automatic conversion formulas, with a conversion price based on the greater of: (i) a floor price of $5.00; and (ii) the current market price of our common shares at the time of the trigger event (calculated using a 10-day weighted average). Based on a floor price of $5.00, these NVCC capital instruments would be converted into approximately 4.0 billion BMO common shares, assuming no accrued interest and no declared and unpaid dividends.

Other Capital Developments

During the quarter, we issued $435 million common shares through the DRIP and the exercise of stock options.

On January 31, 2023, we completed the domestic public offering of $650 million Non-Cumulative 5-Year Fixed Rate Reset Class B Preferred Shares, Series 52 (NVCC).

On January 25, 2023, we completed the private placement of $750 million common share with BNP Paribas SA. On December 16, 2022, we completed a public offering and a concurrent private placement for a total issuance of $2.6 billion common shares. The common shares were issued to align our capital position with increased regulatory requirements and for general corporate purposes.

On December 1, 2022, we issued 1,162,711 shares for $153 million for the acquisition of Radicle Group Inc.

Dividends

On May 24, 2023, BMO announced that the Board of Directors had declared a quarterly dividend on common shares of $1.47 per share, an increase of $0.04 from the prior quarter and an increase of $0.08 or 6% from the prior year. The dividend is payable on August 28, 2023 to shareholders of record on July 28, 2023. Common shareholders may elect to have their cash dividends reinvested in common shares of BMO, in accordance with the DRIP. Until further notice, common shares under the DRIP will be issued by the bank from treasury with a 2% discount, calculated in accordance with the terms of the DRIP. The discount will not apply to common shares purchased under the “Optional Cash Payment” feature of the DRIP.

For the purposes of the Income Tax Act (Canada) and any similar provincial and territorial legislation, BMO designates all dividends paid or deemed to be paid on both its common and preferred shares as “eligible dividends”, unless indicated otherwise.

BMO Financial Group Second Quarter Report 2023 25

Review of Operating Groups’ Performance

How BMO Reports Operating Group Results

BMO reports financial results for its three operating groups, one of which comprises two operating segments, all of which are supported by Corporate Units and Technology and Operations within Corporate Services. Operating segment results include treasury-related allocations in revenue, non-interest expense allocations from Corporate Units and Technology and Operations (T&O) and allocated capital. The impact of the acquisition is reflected in our current quarter and year-to-date results as a business combination, with operating results primarily allocated to our U.S. P&C and BMO Wealth Management businesses based on Bank of the West’s client segmentation and allocation methodologies which may change after conversion.

BMO employs funds transfer pricing and liquidity transfer pricing between treasury and the operating segments in order to assign the appropriate cost and credit to funds for the appropriate pricing of loans and deposits, and to help assess the profitability performance of each line of business. In addition, these practices capture the cost of holding supplemental liquid assets to meet contingent liquidity requirements, as well as facilitating the management of interest rate risk and liquidity risk within our risk appetite framework and regulatory requirements. We review our transfer pricing methodologies at least annually, to align with our interest rate, liquidity and funding risk management practices.

The costs of Corporate Units and T&O services are largely allocated to the four operating segments, with any remaining amounts retained in Corporate Services. Expenses directly incurred to support a specific operating segment are generally allocated to that operating segment. Other expenses that are not directly attributable to a specific operating segment are allocated across the operating segments, reasonably reflective of the level of support provided to each operating segment. We review these expense allocation methodologies periodically.

Capital is allocated to the operating segments based on the amount of regulatory capital required to support business activities. Effective the first quarter of fiscal 2023, our capital allocation rate increased to 11.0% of risk weighted assets, compared with 10.5% in fiscal 2022 to reflect increased capital requirements. Unallocated capital is reported in Corporate Services. We review our capital allocation methodologies annually.

Periodically, certain lines of business and units within our organizational structure are realigned to support our strategic priorities and prior periods have been reclassified to conform with the current period’s presentation.

We analyze revenue at the consolidated level based on GAAP revenue as reported in the audited annual consolidated financial statements, rather than on a taxable equivalent basis (teb), which is consistent with our Canadian banking peer group. Like many banks, BMO analyzes revenue on a teb basis at the operating segment level. Revenue and the provision for income taxes in BMO Capital Markets and U.S. Personal and Commercial Banking are increased on tax-exempt securities to an equivalent pre-tax basis in order to facilitate comparisons of income between taxable and tax-exempt sources. The offset to the operating segment teb adjustments is reflected in Corporate Services revenue and provision for (recovery of) income taxes.

Total revenue was $1,586 million, an increase of $22 million or 1% from the prior year.

Adjusted results exclude the impact of the items described in footnotes (2) to (7).

Corporate Services consists of Corporate Units and Technology and Operations (T&O). Corporate Units provide enterprise-wide expertise, governance and support in a variety of areas, including strategic planning, risk management, treasury, finance, legal and regulatory compliance, sustainability, human resources, communications, marketing, real estate, and procurement. T&O develops, monitors, manages and maintains governance of information technology, including data and analytics, and provides cyber security and operations services.

The costs of Corporate Units and T&O services are largely allocated to the four operating segments (Canadian P&C, U.S. P&C, BMO Wealth Management and BMO Capital Markets), with any remaining amounts retained in Corporate Services results. As such, Corporate Services results largely reflect the impact of residual treasury-related activities, the elimination of taxable equivalent adjustments, and residual unallocated expenses.

BMO Financial Group Second Quarter Report 2023 35

Q2 2023 vs. Q2 2022

Corporate Services reported net loss was $1,255 million, compared with a reported net income of $2,466 million, and adjusted net loss was $187 million, compared with $111 million in the prior year. The current quarter included the initial provision for credit losses on the purchased Bank of the West performing loan portfolio. The prior year included the impact of fair value management actions related to the acquisition of Bank of the West, as well as the impact of divestitures related to the sale of our EMEA Asset Management business. Results in both quarters included acquisition and integration costs related to Bank of the West.

Lower revenue was driven by treasury-related activities and lower earnings on the investment of unallocated capital, partially offset by the impact of Bank of the West, including the accretion of purchase accounting fair value marks on loans and deposits and the discount on securities, net of the amortization of the fair value hedge.

Q2 2023 vs. Q1 2023

Reported net loss was $1,255 million, compared with a reported net loss of $2,211 million in the prior quarter, and adjusted net loss was $187 million, compared with $195 million. The current quarter included the adjusting items noted above. In addition, the prior quarter included a loss from the fair value management actions and a tax expense related to certain tax measures enacted by the Canadian government. Reported net loss was lower due to the items noted above.

Adjusted net loss excluded the above factors and was primarily driven by lower expenses and the impact of a more favourable tax rate in the current quarter, partially offset by lower revenue from higher earnings on the investment of unallocated capital in the prior quarter that partially offset the impact of Bank of the West, including the accretion of purchase accounting fair value marks on loans and deposits and the discount on securities, net of the amortization of the fair value hedge.

Q2 YTD 2023 vs. Q2 YTD 2022

Reported net loss was $3,466 million, compared with a reported net income of $2,694 million in the prior year, reflecting the items noted above, as well as a write-down of goodwill related to the sale of our EMEA Asset Management business in the prior year.

Adjusted net loss was $382 million, compared with an adjusted net loss of $241 million in the prior year, due to lower revenue and lower expenses, partially offset by a more favourable tax rate.

Lower revenue was driven by treasury-related activities, including lower securities gains, partially offset by higher earnings on the investment of unallocated capital and the impact of Bank of the West, including the accretion of purchase accounting fair value marks on loans and deposits and the discount on securities, net of the amortization of the fair value hedge.

BMO Financial Group Second Quarter Report 2023 37
---

BMO’s quarterly earnings trends were reviewed in detail in the Summary Quarterly Earnings Trends section of BMO’s 2022 Annual Report. Please refer to that review for a more complete discussion of trends and factors affecting past quarterly results, including the modest impact of seasonal variations in results, such as higher employee expenses due to higher employee benefits and stock-based compensation for employees eligible to retire that are recorded in the first quarter of each year, as well as the impact of fewer days in the second quarter relative to other quarters. Quarterly earnings are also impacted by foreign currency translation. On February 1, 2023, we completed the acquisition of Bank of the West and its subsidiaries. The impact of the acquisition is reflected in our current quarter and year-to-date results as a business combination, with operating results primarily allocated to our U.S. P&C and BMO Wealth Management businesses based on Bank of the West’s client segmentation and allocation methodologies which may change after conversion. We completed the sale of our EMEA Asset Management business in the first quarter of 2022 and the sale of our Private Banking business in Hong Kong and Singapore in the second quarter of 2021. These divestitures were recorded in BMO Wealth Management and reduced overall revenue and expenses in 2022 relative to 2021. The table above outlines summary results for the third quarter of 2021 through the second quarter of 2023.

Earnings Trends

Financial performance in the most recent quarter reflected the inclusion of Bank of the West. The first quarter of 2023 and second half of 2022 was impacted by a higher interest rate environment and volatility in equity markets, with lower client activity in our market sensitive businesses, as well as higher provisions for credit losses. Performance in the first half of 2022 and in 2021 benefitted from stronger markets and client activity in BMO Wealth Management and BMO Capital Markets, as well as good operating momentum across our businesses.

Reported results in the second quarter of 2023 included an initial provision for credit losses on the purchased Bank of the West performing loan portfolio. The first quarter of 2023 and fiscal 2022 included revenue (losses) resulting from fair value management actions related to the impact of interest rate changes between the announcement and closing of the Bank of the West acquisition on its fair value and goodwill. In addition, the first quarter of 2023 included a tax expense related to certain tax measures enacted by the Canadian government, and the fourth quarter of 2022 included a legal provision related to a lawsuit associated with a predecessor bank, M&I Marshall and Ilsley Bank. Results in 2022 and 2021 included the impact of divestitures related to the sale of our EMEA and U.S. Asset Management business. All periods included acquisition and integration costs, and the amortization of acquisition-related intangible assets.

Total revenue reflected the benefit of our diversified businesses. Revenue in our P&C businesses has strengthened in recent quarters, supported by the impact of Bank of the West in U.S. P&C, as well as customer acquisition, higher volumes and margin expansion reflective of the higher rate environment in both Canadian P&C and U.S. P&C. Revenue in BMO Wealth Management benefitted from growth in net interest income, while non-interest revenue was impacted by fluctuations in global markets. Revenue in 2022 was impacted by divestitures. Insurance revenue, net of CCPB, is subject to variability, resulting from changes in interest rates and equity markets. BMO Capital Markets revenue in recent quarters was impacted by a slower underwriting environment. The first quarter of 2023 reflected particularly strong performance across Global Markets and Investment and Corporate Banking.

As the economy recovered from the economic downturn brought on by the pandemic, we recorded lower provisions for credit losses on impaired loans, as well as recoveries of provisions for credit losses on performing loans, which reflected an improving economic outlook, favourable credit conditions and positive credit migration. During the past four quarters, we have seen signs of normalization in credit conditions and modest provisions on performing loans reflecting balance growth, changes the economic outlook, as well as the benefits from risk transfer transactions.

Non-interest expense growth in the current quarter was driven by the inclusion of Bank of the West. Non-interest expense growth in the past four quarters was impacted by higher employee-related costs, including sales force expansion, higher salaries and performance-based compensation, as well as higher technology costs. Expense growth in 2022 was impacted by divestitures.

The effective tax rate has varied with legislative changes; changes in tax policy, including their interpretation by tax authorities and the courts; earnings mix, including the relative proportion of earnings attributable to the different jurisdictions in which we operate, the level of pre-tax income, and the level of investments or securities which generate tax credits, or tax-exempt income from securities. The reported effective tax rate was impacted by certain tax measures enacted by the Canadian government as noted above, the fair value management actions relating to the acquisition of Bank of the West in the preceding five quarters, and the sale of our EMEA and U.S. Asset Management businesses in 2022 and 2021.

Transactions with Related Parties

In the ordinary course of business, we provide banking services to our key management personnel on the same terms that we offer to our preferred customers for those services. Key management personnel are defined as those persons having authority and responsibility for planning, directing and/or controlling the activities of an entity, being the directors and most senior executives of the bank. We provide banking services to our joint ventures and equity-accounted investees on the same terms offered to our customers for these services. We also offer employees a subsidy on annual credit card fees.

The bank’s policies and procedures for related party transactions did not materially change from October 31, 2022, as described in Note 27 of the audited annual consolidated financial statements of BMO’s 2022 Annual Report.

Off-Balance Sheet Arrangements

We enter into a number of off-balance sheet arrangements in the normal course of operations. The most significant of these are structured entities, credit instruments and guarantees, which are described in the Off-Balance Sheet Arrangements section of BMO’s 2022 Annual Report. We consolidate our own securitization vehicles, certain capital and funding vehicles, and other structured entities created to meet our own, as well as our customer’s needs. We do not consolidate Canadian and U.S. customer securitization vehicles, certain capital vehicles, various BMO-managed funds or various other structured entities where investments are held. There have been no significant changes to the bank’s off-balance sheet arrangements since October 31, 2022. Bank of the West acquisition had nominal impact on our off-balance sheet exposure.

Accounting Policies and Critical Accounting Estimates and Judgments

Significant accounting policies are described in BMO’s 2022 Annual Report and in the notes to our annual consolidated financial statements for the year ended October 31, 2022, and in Note 1 of the unaudited interim consolidated financial statements, together with a discussion of certain accounting estimates that are considered particularly important as they require management to make significant judgments, some of which relate to matters that are inherently uncertain. Readers are encouraged to review that discussion in Note 1 of the audited annual consolidated financial statements of BMO’s 2022 Annual Report, as well as the updates provided in Note 1 of the unaudited interim consolidated financial statements.

Allowance for Credit Losses

The allowance for credit losses (ACL) consists of allowances on impaired loans, which represent estimated losses related to impaired loans provided for but not yet written off, and allowances on performing loans, which is the bank’s best estimate of impairment in the existing portfolio for loans that have not yet been individually identified as impaired. Expected credit losses (ECL) are calculated on a probability-weighted basis, based on the economic scenarios described below, and are calculated for each exposure in the portfolio as a function of the probability of default (PD), exposure at default (EAD) and loss given default (LGD), with the timing of the loss also considered. Where there has been a significant increase in credit risk, lifetime ECL is recorded; otherwise 12 months of ECL is generally recorded. A significant increase in credit risk considers many different factors and will vary by product and risk segment. The main factors considered in making this determination are the change in PD since origination and certain other criteria, such as 30-day past due and watchlist status. We may apply experienced credit judgment to reflect factors not captured in the ECL models, including the continuing impact of the uncertain environment on credit conditions and the economy.

Our total allowance for credit losses as at April 30, 2023, was $3,833 million ($2,998 million as at October 31, 2022) and comprised an allowance on performing loans of $3,290 million and an allowance on impaired loans of $543 million ($2,441 million and $557 million, respectively, as at October 31, 2022). The allowance on performing loans increased $849 million from the fourth quarter of 2022, primarily driven by the initial provision on the Bank of the West performing loans, economic uncertainty, portfolio credit migration and growth in certain portfolios, partially offset by a modest improvement in macro-economic variables and movements in foreign exchange rates.

In establishing our allowance for performing loans, we attach probability weightings to three economic scenarios, which are representative of our view of economic and market conditions – a base scenario, which in our view represents the most probable outcome, as well as benign and adverse scenarios, all developed by our Economics group.

When changes in economic performance in the forecasts are measured, we use real GDP as the basis, which acts as the key driver for movements in many of the other economic and market variables used, including the equity volatility index (VIX), corporate BBB credit spreads, unemployment rates, housing price indices and consumer credit. In addition, we also consider industry-specific variables, where applicable. Many of the variables have a high degree of interdependency, and as such, there is no single factor to which the allowances as a whole are sensitive.

Information on the Provision for Credit Losses for the three and six months ended April 30, 2023, can be found in the Total Provision for Credit Losses section.

For additional information, refer to Risk Management section, Allowance for Credit Losses section of BMO’s 2022 Annual Report, Note 4 of the audited annual consolidated financial statements, as well as Note 3 of the unaudited interim consolidated financial statements.

Acquisition of Bank of the West – Valuation of Assets and Liabilities

Significant judgment and assumptions were used to determine fair value of the Bank of the West assets and liabilities, including the loan portfolio, core-deposit and other relationship intangible assets and fixed-maturity deposits.

For additional information, refer to Note 1 to the unaudited interim consolidated financial statements.

Caution

This Accounting Policies and Critical Accounting Estimates and Judgments section contains forward-looking statements. Please refer to the Caution Regarding Forward-Looking Statements.

Future Changes in Accounting Policies

We monitor the potential changes proposed by the International Accounting Standards Board (IASB) and analyze the effect that changes in the standards may have on BMO’s financial reporting and accounting policies. New standards and amendments to existing standards, which are effective for the bank in the future, can be found in Note 1 of the audited annual consolidated financial statements of BMO’s 2022 Annual Report.

Other Regulatory Developments

We continue to monitor and prepare for regulatory developments, including those referenced elsewhere in this document.

For a comprehensive discussion of other regulatory developments, refer to the Enterprise-Wide Capital Management section, the Risks That May Affect Future Results section, the Liquidity and Funding Risk section, and the Legal and Regulatory Risk section of BMO’s 2022 Annual Report.

New Canadian Tax Measures

The 2023 Canadian Federal Budget proposed a number of tax measures, including a tax rule that would, in certain circumstances, deny any deductions for dividends that are received after 2023, an amendment to the definition of “financial service” to make payment card clearing services taxable for GST/HST purposes, retroactive to the enactment of the GST, and a 2% tax on share buybacks that occur on, or after January 1, 2024. In addition, the 2023 Federal Budget reaffirmed Canada’s intention to implement the Organization for Economic Co-operation and Development (OECD)/Group of 20 (G20) Inclusive Framework on Base Erosion and Profit Shifting’s two-pillar plan for international tax reform. Canada has indicated it will adopt Pillar II, which will establish rules for a 15% global minimum tax, for fiscal years of multinational enterprises that begin on or after December 31, 2023.

On December 15, 2022, the Canadian government enacted legislation related to certain tax measures that are applicable to certain Canadian companies in a bank or life insurer group, including a one-time 15% tax (referred to as the Canada Recovery Dividend, or CRD), based on the average taxable income for fiscal 2020 and fiscal 2021, less a $1 billion exemption, payable in equal instalments over five years. The legislation also included a permanent 1.5% increase in the tax rate, based on taxable income above $100 million (effective for taxation years that end after April 7, 2022, and pro-rated for the first year).

In the first quarter of 2023, we recorded a one-time tax expense of $371 million relating to the CRD, as well as the prorated fiscal 2022 impact of the 1.5% increase in tax rate, net of a related remeasurement of our net deferred tax asset.

U.S. Regulatory Developments

Following the closing of the acquisition of the Bank of the West and the increasing size and scope of our U.S. operations, BMO’s U.S. Holding Company, BMO Financial Corp (BFC) is expected to meet the threshold for designation as a Category III firm under the Federal Reserve Board’s Enhanced Prudential Standards. This change will require BFC to meet certain increased regulatory requirements related to capital, liquidity, risk management, and governance.

In addition, the Federal Reserve Board and Federal Deposit Insurance Corporation in the United States have highlighted weaknesses in supervision and regulation practices that contributed to the recent failure of certain U.S. regional banks. In response, regulators expect to improve the speed, force, and agility of supervision in the coming years. BMO expects to meet the increased regulatory requirements by the established timeframes.

On May 11, 2023, the Federal Deposit Insurance Corporation (FDIC) issued a notice of proposed ruling for public comment regarding special assessments on depository institutions, to recover the losses to the Deposit Insurance Fund that were attributable to the costs of covering uninsured deposits of Silicon Valley Bank and Signature Bank. The proposed rule provides that the special assessment would be assessed at an annual rate of approximately 12.5 basis points on a U.S. depository institution’s estimated uninsured deposits. The impact of this proposed ruling on our results will depend on the final rules issued by the FDIC.

Risk Management

BMO’s risk management policies and processes to identify, measure, manage, monitor, mitigate and report its credit and counterparty, market, insurance, liquidity and funding, operational, including technology and cyber-related risks, legal and regulatory, strategic, environmental and social, and reputation risks are outlined in the Enterprise-Wide Risk Management section of BMO’s 2022 Annual Report.

Top and Emerging Risks That May Affect Future Results

BMO’s top and emerging risks and other factors that may affect future results are described in the Enterprise-Wide Risk Management section of BMO’s 2022 Annual Report. The following is an update to the 2022 Annual Report.

Update on General Economic Conditions

BMO is exposed to evolving external economic conditions which have the potential to materially impact our financial results, operational efficiency and strategic direction. Economic conditions in North America face several headwinds, including high inflation, global geopolitical risks (including the ongoing conflict in Ukraine), and high household indebtedness. In addition, recent market volatility caused by certain regional bank failures in the United States and ongoing risks around the U.S. debt limit create potential risks for market stability and economic growth.

Inflation is beginning to slow in Canada and the United States, as supply chain constraints and housing costs are showing signs of easing, as are the responses from central banks to raise interest rates to combat inflation. The Bank of Canada has held rates steady since March 2023, with the Federal Reserve expected to also halt its current tightening cycle by the end of the second quarter of calendar 2023. Any further actions will be dependent on inflation levels, which are expected to continue to slow this year. This is being supported by the recent decline in housing prices, which is mitigating cost pressures from higher mortgage rates. Unemployment rates also remain at, or near, historic lows in North America. While some of these major indicators show positive trends, the failure of several banks in the United States and Europe has created instability in financial markets and across the financial services sector. Mitigating actions taken by the Federal Reserve have eased the immediate short-term concerns in the U.S. regional banking sector, however the potential for contagion could result in a tightening of credit availability and impact economic growth.

The United States Federal Government reached its debt ceiling in January 2023 and the U.S. Treasury implemented extraordinary measures to continue to fund the government which are expected to be exhausted in the coming months. Policymakers are negotiating a potential deal to raise the debt ceiling and avoid a default. Uncertainty as to whether a deal will be achieved, the timing of such deal, and the terms and conditions of such deal, pose a risk to the ongoing stability of financial markets and implications for long-term economic growth.

These risks to the current economic conditions could have a significant impact on our financial results, operational efficiency, and our clients and customers. An economic decline or volatility in financial markets in the coming months could decrease revenue and impact profitability. Elevated financing costs have a direct impact on our clients and customers and could cause strain on household and business balance sheets.

Management regularly monitors the economic environment to understand any significant changes and the impact to our operations and to our clients and customers. Mitigating actions are taken, as appropriate, to respond to such uncertainties to limit any impact to the bank and our results.

Interbank Offered Rate (IBOR) Reform

The transition from London interbank rates (LIBORs) and other IBORs to alternative reference rates continues. The Bank of the West’s exposure to remaining USD LIBOR settings was nominal as at April 30, 2023. As a result, the Bank of the West acquisition did not significantly impact our IBOR transition project or transition risks from our disclosure in Note 1 of our annual consolidated financial statements for the year ended October 31, 2022.

As we approach the June 30, 2023 cessation date for the remaining USD LIBOR settings, our overall USD LIBOR exposures continue to decline and our USD LIBOR derivative exposures largely transitioned after central counterparties converted existing LIBOR trades to Secured Overnight Financing Rate.

Trading Market Risk Measures

Average Total Trading Value at Risk (VaR) decreased while Average Total Trading Stressed Value at Risk (SVaR) increased quarter-over-quarter, due to risk changes in the equity and interest rate portfolios. The decrease in VaR was partially offset by increased market volatility related to the failure of several banks in the United States and Europe.

Structural (Non-Trading) Market Risk

Structural economic value exposure to rising rates and benefit to falling rates increased and earnings benefit to rising rates and exposure to falling rates decreased, compared with January 31, 2023. The prior quarter earnings sensitivity was somewhat elevated due to pre-positioning for the balance sheet acquired from Bank of the West. The bank was intentionally positioned with a shorter duration (and higher earnings sensitivity) to offset the naturally longer duration of the Bank of the West balance sheet. With the acquisition now closed, the current quarter risk metrics reflected a relatively neutral positioning.

(2) The impact of insurance market risk is not reflected in the table. Insurance market risk includes interest rate and equity<br>market risk arising from BMO’s insurance business activities. A 100 basis point increase in interest rates as at April 30, 2023 would result in an increase in earnings before tax of $46 million ($34 million as at January 31,<br>2023 and $39 million as at April 30, 2022). A 100 basis point decrease in interest rates as at April 30, 2023 would result in a decrease in earnings before tax of $54 million ($36 million as at January 31,<br>2023 and $38 million as at April 30, 2022). A 10% increase in equity market values as at April 30, 2023, would result in an increase in earnings before tax of $15 million ($15 million as at January 31, 2023<br>and $20 million as at April 30, 2022). A 10% decrease in equity market values as at April 30, 2023, would result in a decrease in earnings before tax of $13 million ($13 million as at January 31, 2023 and<br>$20 million as at April 30, 2022). BMO may enter into hedging arrangements to offset the impact of changes in equity market values on its earnings and did so during the 2022 fiscal year. The impact of insurance market risk on earnings<br>is reflected in insurance claims, commissions and changes in policy benefit liabilities on the Consolidated Statement of Income, and the corresponding change in the fair value of the bank’s policy benefit liabilities is reflected in other<br>liabilities on the consolidated balance sheet.

Liquidity and Funding Risk

Liquidity and funding risk is managed under a robust risk management framework. There were no material changes in the framework during the quarter.

BMO continued to maintain a strong liquidity position in the second quarter of 2023. Customer loans and deposits both increased with the closing of the Bank of the West Acquisition. Excluding the impact of the Bank of the West acquisition, customer loans increased while customer deposits were largely unchanged in the current quarter. Wholesale funding increased, reflecting net issuances. BMO’s liquidity metrics, including the Liquidity Coverage Ratio (LCR) and Net Stable Funding Ratio (NSFR), remained well above internal targets and regulatory requirements. The Office of the Superintendent of Financial Institutions (OSFI) announced changes to its Liquidity Adequacy Requirements Guideline that are effective April 2023. The changes primarily relate to the calculation of the OSFI Net Cumulative Cash Flow supervisory tool. There was no material impact on our liquidity and funding practices or requirements as a result of these changes.

BMO’s liquid assets are primarily held in our trading businesses, as well as in liquidity portfolios that are maintained for contingent liquidity risk management purposes and as investments of excess structural liquidity. Liquid assets include unencumbered, high-quality assets that are marketable, can be pledged as security for borrowings, and can be converted to cash in a time frame that meets our liquidity and funding requirements. BMO’s liquid assets are summarized in the table below.

In the ordinary course of business, BMO may encumber a portion of cash and securities holdings as collateral in support of trading activities and our participation in clearing and payment systems in Canada, the United States and abroad. In addition, BMO may receive liquid assets as collateral and may re-pledge these assets in exchange for cash or as collateral in support of trading activities. Net unencumbered liquid assets, defined as on-balance sheet assets, such as BMO-owned cash and securities and securities borrowed or purchased under resale agreements, plus other off-balance sheet eligible collateral received, less collateral encumbered, totalled $347.7 billion as at April 30, 2023, compared with $357.0 billion as at January 31, 2023. The decrease in unencumbered liquid assets was primarily due to lower cash and partially offset by higher security balances.

Net unencumbered liquid assets are primarily held at the parent bank level, at our U.S. bank entity BMO Harris Bank, and in our broker/dealer operations. In addition to liquid assets, BMO has access to the Bank of Canada’s lending assistance programs, the Federal Reserve Bank discount window in the United States and European Central Bank standby liquidity facilities.

In addition to cash and securities holdings, BMO may also pledge other assets, including mortgages and loans, to raise long-term secured funding. BMO’s total encumbered assets and unencumbered liquid assets are summarized in the Asset Encumbrance table.

The recent failures of certain U.S. regional banks have resulted in a heightened focus on the impact that rising interest rates have had on the market values of amortized cost and fair value through other comprehensive income portfolios. The carrying value and fair value of our amortized cost securities was $122.1 billion and $113.2 billion as at April 30, 2023, respectively, with an unrealized pre-tax loss of $8.9 billion. More than half of the unrealized loss related to the fair value management actions the bank undertook upon announcement of the acquisition of Bank of the West, which included the purchase of a portfolio of matched duration government debt securities. The majority of these securities were placed in fair value accounting hedges on closing, crystallizing the unrealized loss on those securities which will be recognized as a reduction in interest income over their remaining life. The carrying value of our fair value through other comprehensive income securities was $56.5 billion as at April 30, 2023. The net unrealized loss on fair value through other comprehensive income securities, net of fair value hedges, was $217 million after-tax as at April 30, 2023. For more information on amortized cost and fair value through other comprehensive income securities, refer to Note 2 and Note 12 of the unaudited interim consolidated financial statements.

Funding Strategy

BMO’s funding strategy requires that secured and unsecured wholesale funding used to support loans and less liquid assets must have a term (typically maturing in two to ten years) that will support the effective term to maturity of these assets. Secured and unsecured wholesale funding for liquid trading assets is largely shorter term (maturing in one year or less), aligned with the liquidity of the assets being funded, and is subject to limits on aggregate maturities that are permitted across different periods. Supplemental liquidity pools are funded largely with wholesale term funding.

We maintain a large and stable base of customer deposits that, in combination with our strong capital position, is a source of strength. This supports the maintenance of a sound liquidity position and reduces reliance on wholesale funding. Customer deposits totalled $628.5 billion as at April 30, 2023, increasing from $545.1 billion as at January 31, 2023. The Bank of the West acquisition increased customer deposits by $84.5 billion in the current quarter.

Total secured and unsecured wholesale funding outstanding, which largely consists of negotiable marketable securities, was $261.6 billion as at April 30, 2023, with $77.4 billion sourced as secured funding and $184.2 billion as unsecured funding. Wholesale funding outstanding increased from $251.1 billion as at January 31, 2023, primarily due to net wholesale funding issuances during the quarter. The mix and maturities of BMO’s wholesale term funding are outlined in the following table. Additional information on deposit maturities can be found in the Contractual Maturities of Assets and Liabilities and Off-Balance Sheet Commitments section. We maintain a sizeable portfolio of unencumbered liquid assets, totalling $347.7 billion as at April 30, 2023, that can be monetized to meet potential funding requirements, as described in the Unencumbered Liquid Assets section.

Diversification of our wholesale funding sources is an important part of our overall liquidity management strategy. BMO’s wholesale funding activities are well-diversified by jurisdiction, currency, investor segment, instrument type and maturity profile. BMO maintains ready access to long-term wholesale funding through various borrowing programs, including a European Note Issuance Program, Canadian, Australian and U.S. Medium-Term Note programs, Canadian and U.S. mortgage securitizations, Canadian credit card loans, auto loans and home equity line of credit (HELOC) securitizations, U.S. transportation finance loans, covered bonds, and Canadian and U.S. senior unsecured deposits.

BMO’s wholesale funding plan seeks to ensure sufficient funding capacity is available to execute our business strategies. The funding plan considers expected maturities, as well as asset and liability growth projected for our businesses in our forecasting and planning processes, and assesses funding needs in relation to the sources available. The funding plan is reviewed annually by the senior management committees with specific related responsibilities and approved by the Risk Review Committee, and is regularly updated to reflect actual results and incorporate updated forecast information.

Credit Ratings

The credit ratings assigned to BMO’s short-term and senior long-term debt securities by external rating agencies are important for the bank in raising both capital and funding to support its business operations. Maintaining strong credit ratings allows us to access the wholesale markets at competitive pricing levels. Should BMO’s credit ratings experience a downgrade, our cost of funding would likely increase and our access to funding and capital through the wholesale markets could be reduced. A material downgrade of BMO’s ratings could also have other consequences, including those set out in Note 8 of the audited annual consolidated financial statements of BMO’s 2022 Annual Report.

The credit ratings assigned to BMO’s senior debt by rating agencies are indicative of high-grade, high-quality issues. Moody’s, S&P and DBRS have a stable outlook on BMO and Fitch has a negative outlook.

We are required to deliver collateral to certain counterparties in the event of a downgrade of BMO’s current credit rating. The incremental collateral required is based on mark-to-market exposure, collateral valuations and collateral threshold arrangements, as applicable. As at April 30, 2023, we would be required to provide additional collateral to counterparties totalling $137 million, $396 million and $843 million as a result of a one-notch, two-notch and three-notch downgrade, respectively.

Liquidity Coverage Ratio

The Liquidity Coverage Ratio (LCR) is calculated in accordance with OSFI’s Liquidity Adequacy Requirements Guideline and is summarized in the following table. The LCR is calculated on a daily basis as the ratio of the stock of High-Quality Liquid Assets (HQLA) held to total net stressed cash outflows over the next 30 calendar days. BMO’s HQLA primarily comprises cash, highly-rated debt issued or backed by governments, highly-rated covered bonds and non-financial corporate debt, and non-financial equities that are part of a major stock index. Net cash flows include outflows from deposits, secured and unsecured wholesale funding, commitments and potential collateral requirements, offset by permitted inflows from loans, securities lending activities and other non-HQLA debt maturing over a 30-day horizon. Weightings prescribed by OSFI are applied to cash flows and HQLA to arrive at the weighted values and the LCR. The LCR does not reflect excess liquidity in BMO Financial Corp. (BFC) that is greater than 100%, because of limitations on the transfer of liquidity between BFC and the parent bank. Canadian domestic systemically important banks (D-SIBs), including BMO, are required to maintain a minimum LCR of 100%. The average daily LCR for the quarter ended April 30, 2023 was 129%, equivalent to a $52.0 billion surplus above the regulatory minimum. The LCR decreased 15% from 144% in the prior quarter, due to higher net cash outflows primarily related to the incorporation of Bank of the West business activities into the measure. While banks are required to maintain an LCR of greater than 100% in normal conditions, they are also expected to be able to utilize HQLA during a period of stress, which may result in an LCR of less than 100% during such a period. The LCR is only one measure of a bank’s liquidity position and does not fully capture all of its liquid assets or the funding alternatives that may be available during a period of stress. BMO’s total liquid assets are shown in the Liquid Assets table.

Net Stable Funding Ratio

The Net Stable Funding Ratio (NSFR) is a regulatory liquidity metric that assesses the stability of a bank’s funding profile in relation to the liquidity value of its assets and is calculated in accordance with OSFI’s Liquidity Adequacy Requirements Guideline. Unlike the LCR, which is a short-term metric, the NSFR assesses a bank’s medium-term and long-term resilience. The NSFR is defined as the ratio between the amount of available stable funding (ASF) and the amount of required stable funding (RSF). ASF represents the proportion of capital and liabilities expected to be reliably available over a one-year horizon (including customer deposits, long-term wholesale funding, and capital). The stable funding requirements for each institution are set by OSFI based on the liquidity and maturity characteristics of its balance sheet assets and off-balance sheet exposures. Weightings prescribed by OSFI are applied to notional asset and liability balances to determine ASF and RSF and the NSFR. Canadian domestic systemically important banks (D-SIBs), including BMO, are required to maintain a minimum NSFR of 100%. Both ASF and RSF increased in the quarter primarily due to the impact of the Bank of the West acquisition. BMO’s NSFR was 113% as at April 30, 2023, equivalent to a $79.2 billion surplus above the regulatory minimum. The NSFR decreased from 120% in the prior quarter which was temporarily elevated given the pending closing of the Bank of the West acquisition.

Contractual Maturities of Assets and Liabilities andOff-Balance Sheet Commitments

The tables below show the remaining contractual maturities of on-balance sheet assets and liabilities and off-balance sheet commitments. The contractual maturity of financial assets and liabilities is an input to, but is not necessarily consistent with, the expected maturity of assets and liabilities that is used in the management of liquidity and funding risk. We forecast asset and liability cash flows, under both normal market conditions and a number of stress scenarios, to manage liquidity and funding risk. Stress scenarios include assumptions for loan repayments, deposit withdrawals, and credit commitment and liquidity facility drawdowns by counterparty and product type. Stress scenarios also consider the time horizon over which liquid assets can be monetized and the related discounts (“haircuts”) and potential collateral requirements that may result from both market volatility and credit rating downgrades, among other assumptions.

International Exposures

BMO’s geographic exposures outside of Canada and the United States are subject to a risk management framework that incorporates assessments of the economic and political risk in each region or country, as well as management of exposures within limits based on product, entity and country of ultimate risk. Our exposure to these regions as at April 30, 2023, is set out in the following table.

On October 26, 2021, OSFI recommended that Canadian Global Systemically Important Banks (G-SIBs) cease country-by-country disclosures of European exposures and begin to disclose sovereign exposures at the regional (continent) level, effective the first quarter of 2022.

The table outlines total net exposure for funded lending and undrawn commitments, securities (including cash products, traded credit and credit default swap activity), repo-style transactions and derivatives. Repo-style transactions and derivatives exposure are reported as mark-to-market value. Derivatives exposure incorporates transaction netting where master netting agreements with counterparties have been entered into, and collateral offsets for counterparties where a Credit Support Annex is in effect.

Management considers both reported and adjusted results to be useful in assessing underlying ongoing business performance.

Adjusted Revenue – calculated as revenue excluding the impact of certain non-recurring items, and adjusted net revenue is adjusted revenue, net of CCPB, as set out in<br>the Non-GAAP and Other Financial Measures section.
Adjusted Provision for Credit Losses – calculated as provision for credit losses excluding the impact of certain non-recurring items, as set out in the Non-GAAP and Other Financial Measures section.
--- ---
Adjusted Non-Interest Expense – calculated as non-interest expense excluding the impact of certain non-recurring items, as set out in the Non-GAAP and Other Financial Measures section.
--- ---
Adjusted Net Income – calculated as net income excluding the impact of certain non-recurring items, as set out in the Non-GAAP<br>and Other Financial Measures section.
--- ---

Adjusted Effective Tax Rate is calculated as adjusted provision for income taxes divided by adjusted income before provision for income taxes.

Allowance for Credit Losses represents an amount deemed appropriate by management to absorb credit-related losses on loans and acceptances and other credit instruments, in accordance with applicable accounting standards. Allowance on Performing Loans is maintained to cover impairment in the existing portfolio for loans that have not yet been individually identified as impaired. Allowance on Impaired Loans is maintained to reduce the carrying value of individually identified impaired loans to the expected recoverable amount.

Assets under Administration and Assets under Management refers to assets administered or managed by a financial institution that are beneficially owned by clients and therefore not reported on the balance sheet of the administering or managing financial institution.

Asset-Backed Commercial Paper (ABCP) is a short-term investment. The commercial paper is backed by assets such as trade receivables, and is generally used for short-term financing needs.

Average annual totalshareholder return (TSR) represents the average annual total return earned on an investment in BMO common shares made at the beginning of a fixed period. The return includes the change in share price and assumes dividends received were reinvested in additional common shares.

Average Earning Assets represents the daily average balance of deposits at central banks, deposits with other banks, securities borrowed or purchased under resale agreements, securities, and loans over a one-year period.

Average Net Loans and Acceptances is the daily or monthly average balance of loans and customers’ liability under acceptances, net of the allowance for credit losses, over a one-year period.

Bail-In Debt is senior unsecured debt subject to the Canadian Bail-In Regime. Bail-in debt includes senior unsecured debt issued directly by the bank on or after September 23, 2018, which has an original term greater than 400 days and is marketable, subject to certain exceptions. Some or all of this debt may be statutorily converted into common shares of the bank under the Bail-In Regime if the bank enters resolution.

Bankers’ Acceptances (BAs) are bills of exchange or negotiable instruments drawn by a borrower for payment at maturity and accepted by a bank. BAs constitute a guarantee of payment by the bank and can be traded in the money market. The bank earns a “stamping fee” for providing this guarantee.

BasisPoint is one one-hundredth of a percentage point.

Common Equity Tier 1 (CET1) Capital comprises common shareholders’ equity net of deductions for goodwill, intangible assets, pension assets, certain deferred tax assets and other items, which may include a portion of expected credit loss provisions.

Common Equity Tier 1 (CET1) Ratio is calculated as CET1 Capital, which comprises common shareholders’ equity, net of deductions for goodwill, intangible assets, pension assets, certain deferred tax assets and other items, which may include a portion of expected credit loss provisions, divided by risk-weighted assets. The CET1 Ratio is calculated in accordance with the Office of the Superintendent of Financial Institutions’ (OSFI’s) Capital Adequacy Requirements (CAR) Guideline.

Common Shareholders’ Equity is the most permanent form of capital. For regulatory capital purposes, common shareholders’ equity comprises common shareholders’ equity, net of capital deductions.

Credit and Counterparty Risk is the potential for credit loss due to the failure of an obligor (i.e., a borrower, endorser, guarantor or counterparty) to repay a loan or honour another predetermined financial obligation.

Derivatives are contracts, requiring no initial or little investment, with a value that is derived from movements in underlying interest or foreign exchange rates, equity or commodity prices or other indices. Derivatives are used to transfer, modify or reduce current or expected risks from changes in rates and prices.

Dividend Payout Ratio represents common share dividends as a percentage of net income available to common shareholders. It is computed by dividing dividends per share by basic earnings per share. Adjusted dividend payout ratio is calculated in the same manner, using adjusted net income.

Earnings per Share (EPS) is calculated by dividing net income, after deducting preferred share dividends and distributions on other equity instruments, by the average number of common shares outstanding. Adjusted EPS is calculated in the same manner, using adjusted net income. Diluted EPS, which is BMO’s basis for measuring performance, adjusts for possible conversions of financial instruments into common shares if those conversions would reduce EPS, and is more fully explained in Note 9 of the unaudited interim consolidated financial statements.

Earnings Sensitivity is a measure of the impact of potential changes in interest rates on the projected 12-month pre-tax net income of a portfolio of assets, liabilities and off-balance sheet positions in response to prescribed parallel interest rate movements, with interest rates floored at zero.

Economic Capital is an expression of the enterprise’s capital demand requirement relative to its view of the economic risks in its underlying business activities. It represents management’s estimation of the likely magnitude of economic losses that could occur should severely adverse situations arise. Economic capital is calculated for various types of risk, including credit, market (trading and non-trading), operational non-financial, business and insurance, based on a one-year time horizon using a defined confidence level.

Economic Value Sensitivity is a measure of the impact of potential changes in interest rates on the market value of a portfolio of assets, liabilities and off-balance sheet positions in response to prescribed parallel interest rate movements, with interest rates floored at zero.

Efficiency Ratio (or Expense-to-Revenue Ratio) is a measure of productivity. It is calculated as non-interest expense divided by total revenue on a taxable equivalent basis in the operating groups, expressed as a percentage.

Efficiency Ratio, net of CCPB, is calculated as non-interest expense divided by total revenue, net of insurance claims, commissions and changes in policy benefit liabilities (CCPB). The adjusted efficiency ratio, net of CCPB, is calculated in the same manner, utilizing adjusted revenue, net of CCPB, and adjusted non-interest expense.

Environmental and Social Risk is the potential for loss or harm, directly or indirectly, resulting from environmental or social factors that impact BMO or its customers, and BMO’s impact on the environment.

Fair Value is the amount of consideration that would be agreed upon in an arm’s-length transaction between knowledgeable, willing parties who are under no compulsion to act in an orderly market transaction.

Forwards and Futures are contractual agreements to either buy or sell a specified amount of a currency, commodity, interest-rate-sensitive financial instrument or security at a specified price and date in

52 BMO Financial Group Second Quarter Report 2023

the future. Forwards are customized contracts transacted in the over-the-counter market. Futures are transacted in standardized amounts on regulated exchanges and are subject to daily cash margin requirements.

Gross impaired loans and acceptances (GIL) are calculated as the credit impaired balance of loans and customers’ liability under acceptances.

Hedging is a risk management technique used to neutralize, manage or offset interest rate, foreign currency, equity, commodity or credit risk exposures arising from normal banking activities.

Impaired Loans are loans for which there is no longer reasonable assurance of the timely collection of principal or interest.

Incremental Risk Charge (IRC) complements the VaR and SVaR metrics and represents an estimate of the default and migration risks of non-securitization products held in the trading book with exposure to interest rate risk, measured over a one-year horizon at a 99.9% confidence level.

Insurance Risk is the potential for loss as a result of actual experience differing from that assumed when an insurance product was designed and priced, and comprises claims risk, policyholder behaviour risk and expense risk.

Insurance Revenue, net of CCPB, is insurance revenue, net of insurance claims, commissions and changes in policy benefit liabilities (CCPB).

Legal and Regulatory Risk is the potential for loss or harm resulting from a failure to comply with laws or satisfy contractual obligations or regulatory requirements. This includes the risk of failure to: comply with the law (in letter or in spirit) or maintain standards of care; implement legal or regulatory requirements; enforce or comply with contractual terms; assert non-contractual rights; effectively manage disputes; or act in a manner so as to maintain our reputation.

Leverage Exposures(LE) consist of on-balance sheet items and specified off-balance sheet items, net of specified adjustments.

Leverage Ratio reflects Tier 1 Capital divided by LE.

Liquidity andFunding Risk is the potential for loss if we are unable to meet our financial commitments in a timely manner at reasonable prices as they become due. Financial commitments include liabilities to depositors and suppliers, as well as lending, investment and pledging commitments.

Liquidity Coverage Ratio (LCR) is a Basel III regulatory metric calculated as the ratio of high-quality liquid assets to total net stressed cash outflows over a thirty-day period under a stress scenario prescribed by the Office of the Superintendent of Financial Institutions (OSFI).

Market Risk is the potential for adverse changes in the value of our assets and liabilities resulting from changes in market variables such as interest rates, foreign exchange rates, equity and commodity prices and their implied volatilities, and credit spreads, and includes the risk of credit migration and default in our trading book.

Mark-to-Market represents the valuation of financial instruments at fair value (as defined above) as of the balance sheet date.

Model Risk is the potential for adverse consequences resulting from decisions that are based on incorrect or misused model results. These adverse consequences can include financial loss, poor business decision-making and damage to reputation.

Net Interest Income comprises earnings on assets, such as loans and securities, including interest and certain dividend income, less interest expense paid on liabilities, such as deposits. Net interest income, excluding trading, is presented on a basis that excludes trading-related interest income.

Net InterestMargin is the ratio of net interest income to average earning assets, expressed as a percentage or in basis points. Net interest margin, excluding trading, is computed in the same manner, excluding trading-related interest income and earning assets.

Net Non-Interest Revenue is non-interest revenue, net of insurance claims, commissions and changes in policy benefit liabilities (CCPB).

Net Promoter Score (NPS) is the percentage of surveyed customers who would recommend BMO to a friend or colleague. Data is gathered in a survey that uses a 0–10 point scale. “Detractors” are defined as those who provide a rating of 0–6, “Passives” are defined as those who provide a rating of 7 or 8, and “Promoters” are defined as those who provide a rating of 9 or 10. The NPS score is calculated by subtracting the percentage of “Detractors” from the percentage of “Promoters”.

Net Stable Funding Ratio (NSFR) is a regulatory liquidity measure that assesses the stability of a bank’s funding profile in relation to the liquidity value of its assets and is calculated in accordance with the Office of the Superintendent of Financial Institutions’ (OSFI’s) Liquidity Adequacy Requirements Guideline.

Notional Amount refers to the principal amount used to calculate interest and other payments under derivative contracts. The principal amount does not change hands under the terms of a derivative contract, except in the case of cross-currency swaps.

Off-Balance Sheet FinancialInstruments consist of a variety of financial arrangements offered to clients, which include credit derivatives, written put options, backstop liquidity facilities, standby letters of credit, performance guarantees, credit enhancements, commitments to extend credit, securities lending, documentary and commercial letters of credit, and other indemnifications.

Operating Leverage, net of CCPB, is the difference between revenue, net of CCPB (net revenue), and non-interest expense growth rates. Adjusted net operating leverage is the difference between adjusted revenue, net of CCPB, and adjusted non-interest expense growth rates. The bank evaluates performance using adjusted revenue, net of CCPB.

Operational Non-Financial Risk (ONFR) encompasses a wide range of non-financial risks, including those related to business change, customer trust, reputation and data that can result in financial loss. These losses can stem from inadequate or failed internal processes or systems, human error or misconduct, and external events that may directly or indirectly impact the fair value of assets we fold in our credit or investment portfolios. Examples of these risks include cyber and cloud security risk, technology risk, fraud risk, business continuity risk and human resources risk, but exclude legal and regulatory risk, credit risk, market risk, liquidity risk and other types of financial risk.

Options are contractual agreements that convey to the purchaser the right but not the obligation to either buy or sell a specified amount of a currency, commodity, interest-rate-sensitive financial instrument or security at a fixed future date or at any time within a fixed future period.

Purchased Credit Impaired (PCI)Loans are loans for which the timely collection of interest and principal is no longer reasonably assured. These loans are credit-impaired upon initial recognition.

Pre-Provision, Pre-Tax Earnings (PPPT) is calculated as income before the provision for income taxes and provision for/(recovery of) credit losses. We use PPPT on both a reported and adjusted basis to assess our ability to generate sustained earnings growth excluding credit losses, which are impacted by the cyclical nature of a credit cycle.

Provision for Credit Losses (PCL) is a charge to income that represents an amount deemed adequate by management to fully provide for impairment in a portfolio of loans and acceptances and other credit instruments, given the composition of the portfolio, the probability of default, the economic environment and the allowance for credit losses already established. PCL can comprise both a provision for credit losses on impaired loans and a provision for credit losses on performing loans. For more information, refer to the Credit and Counterparty Risk – Provision for Credit Losses and Critical Accounting Estimates and Judgments – Allowance for Credit Losses sections and Note 3 of the unaudited interim consolidated financial statements.

BMO Financial Group Second Quarter Report 2023 53

Reputation Risk is the potential for loss or harm to the BMO brand. It can arise even if other risks are managed effectively.

Return on Equity or Return on Common Shareholders’ Equity (ROE) is calculated as net income, less preferred dividends and distributions on other equity instruments, as a percentage of average common shareholders’ equity. Common shareholders’ equity comprises common share capital, contributed surplus, accumulated other comprehensive income (loss) and retained earnings. Adjusted ROE is calculated using adjusted net income rather than net income.

Return on Tangible Common Equity (ROTCE) is calculated as net income available to common shareholders, adjusted for the amortization of acquisition-related intangible assets, as a percentage of average tangible common equity. Adjusted ROTCE is calculated using adjusted net income rather than net income.

Risk-Weighted Assets (RWA) are defined as on-balance sheet and off-balance sheet exposures that are risk-weighted based on guidelines established by the Office of the Superintendent of Financial Institutions (OSFI). The measure is used for capital management and regulatory reporting purposes.

Securities Borrowed or Purchased under Resale Agreements are low-cost, low-risk instruments, often supported by the pledge of cash collateral, which arise from transactions that involve the borrowing or purchasing of securities.

SecuritiesLent or Sold under Repurchase Agreements are low-cost, low-risk liabilities, often supported by cash collateral, which arise from transactions that involve the lending or selling of securities.

Securitization is the practice of selling pools of contractual debts, such as residential mortgages, auto loans and credit card debt obligations, to third parties or trusts, which then typically issue a series of asset-backed securities to investors to fund the purchase of the contractual debts.

Strategic Risk arises from the possibility that the bank could experience financial loss or other types of harm due to changes in the external business environment and failure to respond effectively to these changes as a result of inaction, inappropriate strategies or poor implementation of strategies. Strategic risk also includes business risk, which arises from the specific business activities of the enterprise, and the effects these could have on its earnings.

Stressed Value at Risk (SVaR) measures the maximum loss likely to be experienced in the trading and underwriting portfolios, measured at a 99% confidence level over a one-day holding period, with model inputs calibrated to historical data from a period of significant financial stress. SVaR is calculated for specific classes of risk in BMO’s trading and underwriting activities related to interest rates, foreign exchange rates, credit spreads, equity and commodity prices and their implied volatilities.

Structured Entities (SEs) include entities for which voting or similar rights are not the dominant factor in determining control of the entity. BMO is required to consolidate a SE if it controls the entity by having power over the entity, exposure to variable returns as a result of its involvement and the ability to exercise power to affect the amount of those returns.

Structural (Non-Trading) Market Risk comprises interest rate risk arising from banking activities (loans and deposits) and foreign exchange risk arising from foreign currency operations and exposures.

Swaps are contractual agreements between two parties to exchange a series of cash flows. The various swap agreements that BMO enters into are as follows:

Commodity swaps – counterparties generally exchange fixed-rate and floating rate payments based on a notional value of a single commodity.
Credit default swaps – one counter party pays the other a fee in exchange for an agreement by the other counterparty to make a payment if a credit event occurs, such as bankruptcy or failure to pay.
--- ---
Cross-currency interest rate swaps – fixed rate and floating-rate interest payments and principal amounts are exchanged in different currencies. Cross-currency swaps – fixed-rate interest payments and<br>principal amounts are exchanged in different currencies.
--- ---
Equity swaps – counterparties exchange the return on an equity security or a group of equity securities for a return based on a fixed or floating interest rate or the return on another equity security or<br>group of equity securities.
--- ---
Interest rate swaps – counterparties generally exchange fixed-rate and floating rate interest payments based on a notional value in a single currency.
--- ---
Total return swaps – one counterparty agrees to pay or receive from the other cash amounts based on changes in the value of a reference asset or group of assets, including any returns such as interest earned<br>on these assets, in exchange for amounts that are based on prevailing market funding rates.
--- ---

Tangible Common Equity is calculated as common shareholders’ equity, less goodwill and acquisition-related intangible assets, net of related deferred tax liabilities.

Taxable Equivalent Basis (teb): Operating segment revenue is presented on a taxable equivalent basis (teb). Revenue and the provision for income taxes in BMO Capital Markets and U.S. Personal and Commercial Banking are increased on tax-exempt securities to an equivalent pre-tax basis to facilitate comparisons of income between taxable and tax-exempt sources. The offset to operating segment teb adjustments is reflected in Corporate Services revenue and provision for (recovery) income taxes.

Tier 1 Capital comprises CET1 Capital and Additional Tier 1 (AT1) Capital. AT1 Capital consists of preferred shares and other AT1 Capital instruments, less regulatory deductions.

Tier 1 Capital Ratio reflects Tier 1 Capital divided by risk-weighted assets.

Tier 2 Capital comprises subordinated debentures and may include certain credit loss provisions, less regulatory deductions.

Total Capital includes Tier 1 and Tier 2 Capital.

Total CapitalRatio reflects Total Capital divided by risk-weighted assets.

Total Loss Absorbing Capacity (TLAC) comprises Total Capital and senior unsecured debt subject to the Canadian Bail-In Regime, less regulatory deductions.

Total Loss Absorbing Capacity (TLAC) Ratio reflects TLAC divided by risk-weighted assets.

Total Loss Absorbing Capacity (TLAC) Leverage Ratio reflects TLAC divided by leverage exposures.

Total Shareholder Return: The annual total shareholder return (TSR) represents the average annual total return earned on an investment in BMO common shares made at the beginning of the respective period. The return includes the change in share price and assumes dividends received were reinvested in additional common shares.

Trading and Underwriting Market Risk is associated with buying and selling financial products in the course of meeting customer requirements, including market-making and related financing activities, and assisting clients to raise funds by way of securities issuance.

Trading-Related Revenue includes net interest income and non-interest revenue earned from on-balance sheet and off-balance sheet positions undertaken for trading purposes. The management of these positions typically includes marking them to market on daily basis. Trading-related revenue also includes income (expense) and gains (losses) from both on-balance sheet instruments and interest rate, foreign exchange (including spot positions), equity, commodity and credit contracts.

Value-at-Risk (VaR) measures the maximum loss likely to be experienced in the trading and underwriting portfolios, measured at a 99% confidence level over a one-day holding period. VaR is calculated for specific classes of risk in BMO’s trading and underwriting activities related to interest rates, foreign exchange rates, credit spreads, equity and commodity prices and their implied volatilities.

Notes to Interim Consolidated Financial Statements

April 30, 2023 (Unaudited)

Note 1: Basis of Presentation

Bank of Montreal (the bank or BMO) is a chartered bank under the Bank Act (Canada) and is a public company incorporated in Canada. We are a highly diversified financial services company, providing a broad range of personal and commercial banking, wealth management and investment banking products and services. The bank’s head office is at 129 rue Saint Jacques, Montreal, Quebec. Our executive offices are at 100 King Street West, 1 First Canadian Place, Toronto, Ontario. Our common shares are listed on the Toronto Stock Exchange (TSX) and the New York Stock Exchange.

These condensed interim consolidated financial statements have been prepared in accordance with International Accounting Standard 34, Interim Financial Reporting as issued by the International Accounting Standards Board (IASB) using the same accounting policies as disclosed in our annual consolidated financial statements for the year ended October 31, 2022, with the addition of purchased loan accounting in Note 3 and non-controlling interests, described below, as a result of our acquisition of Bank of the West and its subsidiaries (Bank of the West). Refer to Note 12 for more details. These condensed interim consolidated financial statements should be read in conjunction with the notes to our annual consolidated financial statements for the year ended October 31, 2022. We also comply with interpretations of International Financial Reporting Standards (IFRS) by our regulator, the Office of the Superintendent of Financial Institutions of Canada (OSFI). These interim consolidated financial statements were authorized for issue by the Board of Directors on May 24, 2023.

Non-Controlling Interest in Subsidiaries

Non-controlling interest in subsidiaries is presented in our Consolidated Balance Sheet as a separate component of equity that is distinct from our shareholders’ equity. The net income attributable to non-controlling interest in subsidiaries is presented separately in our Consolidated Statement of Income.

Interbank Offered Rate (IBOR) Reform

The transition from London Interbank rates (LIBORs) and other IBORs to alternative reference rates continues. The Bank of the West’s exposure to remaining USD LIBOR settings was nominal as at April 30, 2023. Hence, the Bank of the West acquisition did not significantly impact the project or transition risks from our disclosure in Note 1 of our annual consolidated financial statements for the year ended October 31, 2022.

As we approach the June 30, 2023 cessation date for the remaining USD LIBOR settings, our overall USD LIBOR exposures continue to decline and our USD LIBOR derivative exposures will largely transition when central counterparties convert existing LIBOR trades to Secured Overnight Financing Rate.

Use of Estimates and Judgments

The preparation of the interim consolidated financial statements requires management to use estimates and assumptions 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; financial instruments measured at fair value; pension and other employee future benefits; impairment of securities; income taxes and deferred tax assets; goodwill and intangible assets; insurance-related liabilities; provisions including legal proceedings and restructuring charges; transfer 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 for Canada and the U.S. is subject to several risks that could lead to a severe downturn, including persistent high inflation leading to significant further increases in interest rates, continued stress in the U.S. regional banking sector, an escalation of the conflict in Ukraine, and an increase in geopolitical tensions between the U.S. and China. In addition, the U.S. Congress will need to raise the debt ceiling soon to avoid a potential default that could lead to financial market turbulence and a much weaker economy. The impact on our business, results of operations, reputation, financial performance and condition, including the potential for credit, counterparty and mark-to-market losses, our credit ratings and regulatory capital and liquidity ratios, as well as impacts to our customers and competitors, will depend on future developments, which remain uncertain. By their very nature, the judgments and estimates we make for the purposes of preparing our consolidated financial statements relate to matters that are inherently uncertain. However, we have detailed policies and internal controls that are intended to ensure the judgments made in estimating these amounts are well controlled and independently reviewed, and that our policies are consistently applied from period to period. We believe that our estimates of the value of our assets and liabilities are appropriate as at April 30, 2023.

Allowance for Credit Losses

As detailed further in Note 1 of our annual consolidated financial statements for the year ended October 31, 2022, the allowance for credit losses (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 loss (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.

60<br> BMO Financial Group Second Quarter Report 2023

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 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-day 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 expected credit losses, we must rely on estimates and exercise judgment 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 decrease in the allowance for credit losses. The calculation of expected credit losses 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 primary operating markets of Canada, the United States (U.S.) 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 expected credit loss. The allowance is sensitive to changes in both economic forecasts and the probability-weight assigned to each forecast scenario.

Additional information regarding the allowance for credit losses is included in Note 3.

Acquisition of Bank of the West - Valuation of Assets and Liabilities

Significant judgment and assumptions were used to determine the fair value of the Bank of the West assets acquired and liabilities assumed, including the loan portfolio, core-deposit and other relationship intangible assets and fixed-maturity deposits.

For loans, the determination of fair value involved estimating the cash flows which are expected to be received on all purchased loans and discounting these back to their present value. We estimated expected cash flows based on models that incorporate management’s best estimate of current key assumptions such as default rates, loss severity, timing of prepayments and collateral. In determining the discount rate, we considered various factors, including our cost to raise funds in the current market, the risk premium associated with the loans and the cost to service the portfolios.

For core-deposit intangible assets, fair value was determined using a discounted cash flow approach, comparing the present value of the cost to maintain the acquired deposits and to the cost of alternative funding. The present value of the cost to maintain the acquired deposits includes an estimate of future interest costs and operating expenses for the core deposits acquired. Core deposits are those that we considered to be a stable, below-market sources of funding. Deposit run-off was estimated using historical attrition data, comparing this to market sources at the date of acquisition.

We calculated the fair value of wealth management and credit card customer relationships acquired based on the excess of estimated future cash inflows (i.e. revenue from the acquired relationships) over the related estimated cash outflows (i.e. operating costs and contributory asset charges) over the estimated useful life of the customer base.

The determination of the fair value of fixed-maturity deposits involved estimating the cash flows to be paid and discounting these back to their present value. The timing and amount of cash flows include significant management judgment regarding the likelihood of early redemption and the timing of withdrawal by the customer. Discount rates were based on the prevailing rates we were paying on similar deposits at the date of acquisition.

The fair value of all other assets and liabilities, including real estate properties, was calculated using market data where possible, as well as management judgment to determine the price that would be obtained in an arms-length transaction between knowledgeable, willing parties.

Additional information regarding the accounting for the acquisition is included in Note 3 and Note 12.

Note 3: Loans and Allowance for Credit Losses

Purchased Loans

Purchased loans are initially measured at fair value and identified as either purchased performing loans (those that continued to make timely principal and interest payments), or purchased credit impaired loans (those for which the timely collection of interest and principal is no longer reasonably assured). These loans are subsequently measured at amortized cost.

Purchased Performing Loans

For loans with fixed terms, the fair value mark is amortized into interest income over the expected life of the loan using the effective interest method. For loans with revolving terms, the fair value mark is amortized into net interest income on a straight-line basis over the contractual term of the loans. As loans are repaid, the remaining unamortized fair value mark related to those loans is recorded in interest income in the period the loan is repaid. All purchased performing loans were initially recorded in Stage 1 for purposes of determining expected credit losses.

On February 1, 2023, we recognized purchased performing loans with a fair value of $76,068 million. Fair value reflects estimates of expected future credit losses at the acquisition date of $1,047 million as well as interest rate premiums or discounts relative to prevailing market rates. Gross contractual receivables amounted to $78,931 million. As at April 30, 2023, purchased performing loans on the Consolidated Balance Sheet totalled $70,530 million, including a remaining fair value mark of $(2,679) million.

Purchased Credit Impaired (PCI) Loans

Subsequent to the acquisition date, we will regularly re-evaluate what we expect to collect on the purchased credit impaired loans. Increases in expected cash flows will result in a recovery of the provision for credit losses and either a reduction in any previously recorded allowance for credit losses or, if no allowance exists, an increase in the current carrying value of the purchased loans. Decreases in expected cash flows will result in a charge to the provision for credit losses and an increase to the allowance for credit losses. We will record interest income using the effective interest method over the effective life of the loan. PCI loans are presented within Stage 3.

On February 1, 2023, we recognized purchased credit impaired loans with a total fair value of $415 million, including a fair value mark of

$(168)

million.

Commitments and Letters of Credit Acquired

As part of our acquisition of Bank of the West, we recorded a liability related to unfunded commitments and letters of credit. The total fair value mark associated with unfunded commitments and letters of credit is amortized into net interest income on a straight-line basis over the contractual term of the acquired commitments. All purchased commitments and letters of credit are included in Stage 1 for purposes of determining expected credit losses. ECL is recorded on these commitments in normal course.

Allowance for Credit Losses

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 $3,833 million at April 30, 2023 ($2,998 million as at October 31, 2022) of which $3,350 million ($2,617 million as at October 31, 2022) was recorded in loans and $483 million ($381 million as at October 31, 2022) was recorded in other liabilities in our Consolidated Balance Sheet.

Significant changes in gross balances, including originations, maturities and repayments in the normal course of operations, impact the allowance for credit losses. In addition, the purchased performing loans we acquired in the Bank of the West acquisition are subject to ECL on acquisition date, consistent with the process followed for originated loans. An initial provision for credit losses of $705 million was recorded in the Consolidated Statement of Income.

The following tables show the continuity in the loss allowance by product type for the three and six months ended April 30, 2023 and April 30, 2022. Transfers represent the amount of ECL that moved between stages during the period, for example, moving from a 12-month (Stage 1) to lifetime (Stage 2) ECL measurement basis. Net remeasurements represent the ECL impact due to transfers between stages, as well as changes in economic forecasts and credit quality. Model changes include new calculation models or methodologies.

Loans Past Due Not Impaired

Loans that are past due but not classified as impaired are loans where our customers have failed to make payments when contractually due but for which we expect the full amount of principal and interest payments to be collected, or loans which are held at fair value. The following table presents loans that are past due but not classified as impaired as at April 30, 2023 and October 31, 2022. Loans less than 30 days past due are excluded as they are not generally representative of the borrower’s ability to meet their payment obligations.

Fully secured loans with amounts between 90 and 180 days past due that we have not classified as impaired totalled $13 million and $43 million as at April 30, 2023 and October 31, 2022, respectively.

ECL Sensitivity and Key Economic Variables

The expected credit loss 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 impairment allowances as a whole are sensitive.

The benign scenario as at April 30, 2023 involves a materially stronger economic environment than the base case forecast, with a considerably lower unemployment rate.

As at April 30, 2023, our base case scenario depicts a mild economic downturn in near-term largely in response to higher interest rates, and a moderate economic recovery over the medium-term projection period as inflation is expected to ease and lead to lower interest rates. Our base case economic forecast as at October 31, 2022, depicted a stronger economic forecast in the near-term projection period and a weaker economic forecast over the long-term projection period.

If we assumed a 100% base case economic 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 $2,475 million as at April 30, 2023 ($1,900 million as at October 31, 2022), compared to the reported allowance for performing loans of $3,290 million ($2,441 million as at October 31, 2022).

6<br>8<br> BMO Financial Group Second Quarter Report 2023

As at April 30, 2023, our adverse economic scenario depicts a sizeable contraction in the Canadian and U.S. economy in the near-term. The adverse case as at October 31, 2022 depicted a somewhat less severe, albeit still negative, economic environment in Canada and the U.S. If we assumed a 100% adverse economic 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 $5,100 million as at April 30, 2023 ($3,250 million as at October 31, 2022), compared to the reported allowance for performing loans of $3,290 million ($2,441 million as at October 31, 2022).

Actual results in a recession will differ as our portfolio will change through time due to migration, growth, risk mitigation actions and other factors. In addition, our allowance will reflect the three economic scenarios used in assessing the allowance, with weightings attached to adverse and benign scenarios often unequally weighted and the weightings will change through time.

The following table shows the key economic variables used to estimate the allowance on performing loans forecast over the next 12 months or lifetime measurement period. While the values disclosed below are national variables, we use regional variables in the underlying models and consider factors impacting particular industries where appropriate.

The ECL approach requires the recognition of credit losses generally based on 12 months of expected losses for performing loans (Stage 1) and the recognition of lifetime expected losses for performing loans that have experienced a significant increase in credit risk since origination (Stage 2). Under our current probability-weighted scenarios, if all our performing loans were in Stage 1, our models would generate an allowance for performing loans of approximately $2,650 million ($1,850 million as at October 31, 2022), compared to the reported allowance for performing loans of $3,290 million ($2,441 million as at October 31, 2022).

(2) If converted, the holders have the option to convert back to the original preferred shares on subsequent redemption dates, subject to certain conditions.
--- ---
(3) The instruments issued include a <br>non-viability<br> contingent capital (NVCC) provision, which is necessary for the preferred shares, AT1 Notes and by virtue of the recourse to the Preferred Shares Series 48, Preferred Shares Series 49 and Preferred Shares Series 51 (collectively, the LRCN Preferred Shares) for Series 1, Series 2 and Series 3 LRCNs (collectively, the LRCNs), respectively, to qualify as regulatory capital under Basel III, (see (4) below). As such, they are convertible into a variable number of our common shares if OSFI announces that the bank is, or is about to become, <br>non-viable<br> 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, to avoid <br>non-viability.<br> In such an event, each preferred share, including the LRCN Preferred Shares and AT1 Notes, is convertible into common shares pursuant to an automatic conversion formula and a conversion price based on the greater of: (i) a floor price of $5.00 and (ii) the current market price of our common shares based on the volume weighted average trading price of our common shares on the TSX. The number of common shares issued is determined by dividing the value of the preferred share or other equity instrument, including declared and unpaid dividends, by the conversion price and then applying the multiplier.
--- ---
(4) Non-deferrable interest is payable semi-annually on the LRCNs at the bank’s discretion. Non-payment of interest will result in a recourse event, with the noteholders’ sole remedy being the holders’ proportionate share of trust assets comprised of the LRCN Preferred Shares, each series of which is issued concurrently with the corresponding LRCNs and are eliminated on consolidation. In such an event, the delivery of the trust assets will represent the full and complete extinguishment of our obligations under the LRCNs. In circumstances where the LRCN Preferred Shares are converted into common shares of the bank under the NVCC provision, the LRCNs would be redeemed and the noteholders’ sole remedy would be their proportionate share of trust assets, then comprised of common shares of the bank received by the trust on conversion.
--- ---
(5) The rates represent the annual interest rate percentage applicable to the notes issued as at the reporting date.

(6) Represents year-to-date dividends declared per share as at reporting date. <br>Non-cumulative<br> dividends on preferred shares are payable quarterly as and when declared by the Board of Directors, except for Class B – Series 50 and 52 preferred share dividends, which are payable semi-annually.

(7) The stock options issued under the Stock Option Plan are convertible into 6,793,906 common shares as at April 30, 2023 (5,976,870 common shares as at October 31, 2022) of which 3,071,192 are exercisable as at April 30, 2023 (2,648,426 as at October 31, 2022).

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 non-viability contingent capital (NVCC). Semi-annual distributions 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 January 31, 2023, we issued 650,000 Non-Cumulative

5-Year Fixed Rate Reset Class B Preferred Shares Series 52 (NVCC) at a price of $1,000 per share for gross proceeds of $650 million. For the initial fixed rate period to, but excluding May 26, 2028, the shares pay non-cumulative preferential fixed semi-annual cash dividends, as and when declared, in the amount of $70.57 per share per annum, to yield 7.057% annually. The dividend rate will reset on May 26, 2028 and every fifth year thereafter at a rate equal to the 5-year Government of Canada bond yield plus 4.250%.

Common Shares

On December 1, 2022, we issued 1,162,711 shares for $153 million for the acquisition of Radicle Group Inc. Refer to Note 12 for further information.

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 debt 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 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.

72<br> BMO Financial Group Second Quarter Report 2023

The extent of our use of actively quoted market prices (Level 1), internal models using observable market information as inputs (Level 2) and models without observable market information as inputs (Level 3) in the valuation of securities, residential mortgages, business and government loans classified as FVTPL and FVOCI, other assets, fair value liabilities, derivative assets and derivative liabilities is presented in the following table:

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.

(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.

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. Transfers from Level 1 to Level 2 were due to reduced observability of the inputs used to value the securities. Transfers from Level 2 to Level 1 were due to increased availability of quoted prices in active markets.

The following tables present significant transfers between Level 1 and Level 2 for the three and six months ended April 30, 2023 and April 30, 2022:

April 30, 2022, including realized and unrealized gains (losses) included in earnings and other comprehensive in come as well as transfers into and out of Level 3. Transfers from Level 2 into Level 3 were due to an increase in unobservable market inputs used in pricing the securities. Transfers out of Level 3 into Level 2 were due to an increase in observable market inputs used in pricing the securities.

Note 7: Capital Management

Our objective is to maintain a strong capital position in a cost-effective structure that: is appropriate given ou r targ et regulatory capital ratios and internal assessment of required economic capital; underpins our operating groups’ business strategies; supports depositor, investor and regulator confidence, while building long-term shareholder value; and is consistent with our target credit ratings.

As at April 30, 2023, we met OSFI’s target capital ratio requirements, which include a 2.5% Capital Conservation Buffer, a 1.0% Common Equity Surcharge for Domestic Systemically Important Banks (D-SIBs), a Countercyclical Buffer and a 3.0% Domestic Stability Buffer (DSB) applicable to D-SIBs. As announced by OSFI in December 2022, the DSB level was set at 3% of total risk-weighted assets effective February 1, 2023. In addition, OSFI increased the DSB’s range from 0% to 2.5%, to 0% to 4%. Our capital position as at April 30, 2023 is further detailed in the Capital Management section of our interim Management’s Discussion and Analysis.

The domestic implementation of Basel III Reforms related to capital, leverage, liquidity and disclosure requirements were effective in the second quarter of 2023. Capital changes under these reforms include revised rules for credit risk and operational risk. Effective February 1, 2023, D-SIBs are required to meet a 0.5

% buffer requirement for the Leverage and Total Loss Absorbing Capacity (TLAC) Leverage Ratios in addition to the minimum requirements. Revisions related to market risk and credit valuation adjustment risk will become effective in the first quarter of 2024.

Stock Options

We did not g rant any stock options during the three months ended April 30, 2023 or 2022. During the six months ended April 30, 2023, we granted a total of 1,322,817 stock options (1,028,255 stock options during the six months ended April 30, 2022) with a weighted-average fair value of $18.94 per option ($14.17 per option for the six months ended April 30, 2022).

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, 2022
Expected dividend yield 4.5% - 4.6% 4.2%
Expected share price volatility 20.9% 16.8%
Risk-free rate of return 3.2% 1.8% - 1.9%
Expected period until exercise (in years) 6.5 - 7.0 6.5 - 7.0
Exercise price () 122.31 135.58

All values are in US Dollars.

Changes to the input assumptions can result in different fair value estimates.

Note 9: Earnings Per Share

Basic earnings per share is calculated by dividing net income, 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:

Note 10: Income Taxes

During the quarter, the Canadian tax authorities proposed to reassess us for income taxes and interest of approximately $40 million in respect of certain 2018 Canadian corporate dividends. In prior fiscal years, the Canadian tax authorities have reassessed us for additional income tax and interest in an amount of approximately $1,425 million in respect of certain 2011-2017 Canadian corporate dividends. These reassessments and proposals to reassess 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.

On December 15, 2022, the Canadian government enacted legislation related to certain tax measures that are applicable to certain Canadian companies in a bank or life insurer group, including a one-time 15% tax (referred to as the Canada Recovery Dividend, or CRD), based on the average taxable income for fiscal 2020 and fiscal 2021, less a $1 billion exemption, payable in equal instalments over five years. The legislation also included a permanent 1.5% increase in the tax rate, based on taxable income above $100 million (effective for taxation years that end after April 7, 2022 and pro-rated for the first year). In the first quarter of 2023, we recorded a one-time tax expense of $371 million in income tax expense, including $312 million relating to the CRD, and $59  million relating to the pro-rated fiscal 2022 impact of the 1.5% increase in tax rate, net of a related remeasurement of our net deferred tax asset.

Note 11: Operating Segmentation

Certain comparative figures have been reclassified to conform with the current period’s presentation.

Note 12: Acquisitions

Bank of the West

On December 20, 2021, we announced a definitive agreement with BNP Paribas to acquire 100

% of the outstanding shares of Bank of the West, including its subsidiaries. All regulatory approvals for the acquisition were received and the acquisition closed on February 1, 2023, for a cash purchase price of US$

13.8

billion. Bank of the West provides a broad range of banking products and services primarily in the Western and Midwestern parts of the U.S. The merger enables BMO’s market extension in Bank of the West’s primary markets, including California, and accelerates BMO’s commercial banking expansion. The acquisition has been reflected in our results this quarter as a business combination, in the U.S. P&C and BMO WM reporting segments.

As part of the acquisition, we acquired a 51% interest in its subsidiary CLAAS Financial Services, LLC which provides lease and loan financing to commercial entities acquiring agricultural equipment. The bank is the primary beneficiary of this LLC, and it is consolidated in our consolidated financial statements. We have recorded the ownership interests of the other partners in CLAAS Financial Services LLC as non-controlling interest in our Consolidated Balance Sheet.

We acquired intangible assets of $2,892 million and goodwill of $10,495  million. Core-deposit and customer relationship intangible assets will be amortized to income over the period during which we believe the assets will benefit us, on an accelerated basis, over a period not to exceed 15 years. Goodwill consists largely of the synergy and economies of scale expected from the combined operations of BMO and Bank of the West. Goodwill is not deductible for tax purposes.

We recorded the assets acquired and liabilities assumed at fair value as at the date of acquisition, as shown in the table below. The purchase price allocation is subject to refinement as we finalize the valuation of the assets acquired.

All values are in US Dollars.

(1) To mitigate changes in the Canadian dollar equivalent of the purchase price between announcement and close, we entered into forward contracts, which qualified for hedge accounting. Changes in the fair value of these forward contracts of $269 million (after-tax) was accounted for as a reduction of the Canadian dollar equivalent of the purchase price.
(2) The net deferred tax asset recorded in the opening balance sheet is $1,308 million.
--- ---

The purchase price allocation for Bank of the West is subject to refinement as we complete the valuation of the assets acquired and liabilities assumed.

The accounting for purchased loans, including the initial provision for credit losses, is discussed in Note 3.

For the three months ended April 30, 2023, Bank of the West contributed revenue of $1,072 million and net income of $153 million to our consolidated results. Net income of $153 million excludes the initial allowance for credit losses of $705 million ($517 million after-tax) and integration and acquisition related costs of $722 million ($545

million after-tax). If we assume the acquisition occurred on November 1, 2022 and the same fair values were applied, we estimate that our c ombined c onsolidated year-to-date revenue and net income would have been $

16  billion and $1.5  billion , respectively.

Impact of Fair Value Management Actions

The fair value of fixed rate loans, securities and deposits is largely dependent on interest rates. As interest rates increased between announcement of the acquisition and close, the fair value of the acquired fixed rate instruments (in particular, loans, securities and deposits) decreased, resulting in higher goodwill on close as compared to our estimates on the announcement date. Conversely, the fair value of floating rate assets (liabilities) and non-maturity deposits approximates par. Changes in goodwill relative to our original assumptions announced on December 20, 2021 impacted capital ratios on close because goodwill is treated as a deduction from capital under OSFI Basel III rules.

Upon announcement of the agreement to acquire Bank of the West, we entered into pay fixed/receive float interest rate swaps and purchased a portfolio of matched duration U.S. Treasuries and other balance sheet instruments to economically hedge the impact of changes in interest rates on our capital ratios at close. We recorded net interest income and mark-to-market gains of $

5.7

billion on these instruments, in interest income and non-interest revenue between December 20, 2021 and February 1, 2023, at which time the interest rate swaps were settled. The gains provided additional capital to offset the impact of higher goodwill on close.

On close, we placed the majority of these U.S. Treasuries and other balance sheet instruments, which were in an unrealized loss position, in fair value hedge relationships with new pay fixed/receive float interest rate swaps. The fair value hedges, coupled with other actions taken to manage our interest rate risk profile to its target position, crystallized a $5.7 billion loss on these instruments, which will be recognized as a reduction in interest income over their remaining life through accounting for the new fair value hedges. In the quarter, $

289

million was recorded in our Consolidated Statement of Income as a reduction in interest, dividend and fee income – securities, related to the fair value hedge.

Conversely, the fair values of the loans, securities and deposits we acquired are below par. This discount will accrete to interest income in our Consolidated Statement of Income over the remaining term of these instruments. In the quarter, $

253 million and $140
