Summary

The Accelerated Return Notes ® Linked to the EURO STOXX 50 ® Index, due December 28, 2026 (the “notes”) are our senior unsecured debt securities. The notes are not insured by the Canada Deposit Insurance Corporation or the Federal Deposit Insurance Corporation, or secured by collateral. The notes rank equally with all of our other unsecured senior debt from time to time outstanding. Any payments due on the notes, including any repayment of principal, are subject to our credit risk.

The notes provide you a leveraged return, subject to a cap, if the Ending Value of the Market Measure, which is the EURO STOXX 50 ® Index (the “Index”), is greater than the Starting Value. If the Ending Value is equal to the Starting Value, you will receive the principal amount of your notes. If the Ending Value is less than the Starting Value, you will lose all or a portion of the principal amount of your notes. Any payments on the notes will be calculated based on the $10 principal amount per unit and will depend on the performance of the Index, subject to our credit risk. See “Terms of the Notes” below.

Our initial estimated value of the notes equals the sum of the values of the following hypothetical components:

· a fixed-income debt component with the same tenor as the notes, valued using our internal funding rate for structured notes; and

· one or more derivative transactions relating to the economic terms of the notes.

The internal funding rate used in the determination of the initial estimated value generally represents a discount from the credit spreads for our conventional fixed-rate debt. The value of these derivative transactions is derived from our internal pricing models. These models are based on factors such as the traded market prices of comparable derivative instruments and on other inputs, which include volatility, dividend rates, interest rates and other factors. As a result, the initial estimated value of the notes is based on market conditions at the time it is calculated.

The economic terms of the notes (including the Capped Value) are based on our internal funding rate described above. Our internal funding rate is typically lower than the rate we would pay when we issue conventional fixed or floating rate debt securities. This difference in funding rate, as well as the underwriting discount and the hedging related charge described below, will reduce the economic terms of the notes to you and the initial estimated value of the notes on the pricing date. Due to these factors, the public offering price you pay to purchase the notes is greater than the initial estimated value of the notes.

For more information about the initial estimated value and the structuring of the notes, see “Risk Factors” and “Structuring the Notes” below.

Hypothetical Payout Profile and Examples of Payments at Maturity

Accelerated Return Notes ® This graph reflects the returns on the notes, based on the Participation Rate of 300% and the Capped Value of $11.802 per unit. The green line reflects the returns on the notes, while the dotted gray line reflects the returns of a direct investment in the stocks included in the Index, excluding dividends. This graph has been prepared for purposes of illustration only.

The following table and examples are for purposes of illustration only. They are based on hypothetical values and show hypothetical returns on the notes. They illustrate the calculation of the Redemption Amount and total rate of return based on a hypothetical Starting Value of 100.00, the Participation Rate of 300%, the Capped Value of $11.802 per unit and a range of hypothetical Ending Values. The actual amount you receive and the resulting total rate of return will depend on the actual Starting Value and Ending Value, and whether you hold the notes to maturity. The following examples do not take into account any tax consequences from investing in the notes.

For recent actual levels of the Index, see “The Index” section below. The Index is a price return index and as such the Ending Value will not include any income generated by dividends paid on the stocks included in the Index, which you would otherwise be entitled to receive if you invested in those stocks directly. In addition, all payments on the notes are subject to issuer credit risk.

Risk Factors

There are important differences between the notes and a conventional debt security. An investment in the notes involves significant risks, including those listed below. You should carefully review the more detailed explanation of risks relating to the notes in the “Risk Factors” sections beginning on page PS-5 of product supplement EQUITY ARN-1, page S-2 of the prospectus supplement, and page 9 of the prospectus identified above. We also urge you to consult your investment, legal, tax, accounting, and other advisors before you invest in the notes.

Structure-related Risks

§ Depending on the performance of the Index as measured shortly before the maturity date, your investment may result in a loss; there is no guaranteed return of principal.

§ The notes do not pay interest, and any return on the notes may be less than the yield you could earn by owning a conventional fixed or floating rate debt security of comparable maturity.

§ Any positive return on your investment is limited to the return represented by the Capped Value and may be less than a comparable investment directly in the stocks included in the Index.

§ Payments on the notes are subject to our credit risk, and actual or perceived changes in our creditworthiness are expected to affect the value of the notes. If we become insolvent or are unable to pay our obligations, you may lose your entire investment.

Valuation and Market-related Risks

§ Our initial estimated value of the notes is only an estimate, and is based on a number of factors. The public offering price of the notes may exceed our initial estimated value, because costs associated with offering, structuring and hedging the notes are included in the public offering price, but are not included in the estimated value. These costs will include any underwriting discount and selling concessions and the cost of hedging our obligations under the notes through one or more hedge counterparties (which may be one or more of our affiliates or an agent or its affiliates). Such hedging cost includes our or our hedge counterparty’s expected cost of providing such hedge, as well as the profit we or our hedge counterparty expect to realize in consideration for assuming the risks inherent in providing such hedge.

§ To determine the terms of the notes, we use an internal funding rate that represents a discount from the credit spreads for our conventional fixed-rate debt. As a result, the terms of the notes are less favorable to you than if we had used a higher funding rate.

§ Our initial estimated value of the notes is derived using our internal pricing models. This value is based on market conditions and other relevant factors, which include volatility of the Index, dividend rates and interest rates. Different pricing models and assumptions, including those used by the agent, its affiliates or other market participants, could provide values for the notes that are greater than or less than our initial estimated value. In addition, market conditions and other relevant factors after the pricing date are expected to change, possibly rapidly, and our assumptions may prove to be incorrect. After the pricing date, the value of the notes could change dramatically due to changes in market conditions, our creditworthiness, and the other factors discussed in the next risk factor. These changes are likely to impact the price, if any, at which we, BofAS or any of our respective affiliates would be willing to purchase the notes from you in any secondary market transactions. Our initial estimated value does not represent a minimum price at which we, BofAS or any of our respective affiliates or any other party would be willing to buy your notes in any secondary market at any time.

§ A trading market is not expected to develop for the notes. None of us, MLPF&S, BofAS or any of our respective affiliates is obligated to make a market for, or to repurchase, the notes. There is no assurance that any party will be willing to purchase your notes at any price in any secondary market.

Conflict-related Risks

§ Our business, hedging and trading activities, and those of MLPF&S, BofAS and our respective affiliates (including trading in shares of companies included in the Index), and any hedging and trading activities we, MLPF&S, BofAS or our respective affiliates engage in for our clients’ accounts, may adversely affect the market value of and return on the notes and may create conflicts of interest with you.

§ There may be potential conflicts of interest involving the calculation agents, one of which is our affiliate and one of which is BofAS. We have the right to appoint and remove the calculation agents.

Market Measure-related Risks

§ The Index sponsor may adjust the Index in a way that affects its level, and has no obligation to consider your interests.

§ You will have no rights of a holder of the securities included in the Index, and you will not be entitled to receive securities or dividends or other distributions by the issuers of those securities.

§ While we, MLPF&S, BofAS or our respective affiliates may from time to time own securities of companies included in the Index, we, MLPF&S, BofAS and our respective affiliates do not control any company included in the Index, and have not verified any disclosure made by any company.

§ Your return on the notes may be affected by factors affecting the international securities markets, specifically changes in the countries represented by the Index. In addition, you will not obtain the benefit of any increase in the value of the euro against the U.S. dollar which you would have received if you had owned the securities included in the Index during the term of your notes, although the level of the Index may be adversely affected by general exchange rate movements in the market.

Tax-related Risks

§ The U.S. federal income tax consequences of an investment in the notes are unclear. There is no direct legal authority regarding the proper U.S. federal income tax treatment of the notes and we do not plan to request a ruling from the Internal Revenue Service (the “IRS”) with respect to the notes. Consequently, significant aspects of the tax treatment of the notes are uncertain, and the IRS or a court might not agree with our intended treatment of them, as described in “United States Federal Income Tax Considerations” below. If the IRS were successful in asserting an alternative treatment of the notes, the tax consequences of the ownership and disposition of the notes, including the timing and character of income recognized by U.S. investors, and the withholding tax consequences to non-U.S. investors, might be materially and adversely affected. Moreover, future legislation, Treasury regulations or IRS guidance could adversely affect the U.S. federal income tax treatment of the notes, possibly retroactively.

§ You should review carefully the sections of this term sheet and the accompanying product supplement entitled “United States Federal Income Tax Considerations” and consult your tax advisor regarding the U.S. federal income tax consequences of an investment in the notes, as well as tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

The Index

We obtained all information contained in this term sheet regarding the Index, including, without limitation, its make-up, method of calculation, and changes in its components, from publicly available information. That information reflects the policies of, and is subject to change by, STOXX Limited (“STOXX” or the “Index Sponsor”). STOXX is a wholly owned subsidiary of Deutsche Börse AG. The Index Sponsor has no obligation to continue to publish, and may discontinue publication of, the Index at any time. The consequences of the Index Sponsor discontinuing publication of the Index are discussed in the section entitled “Description of the ARNs—Discontinuance of an Index” in product supplement EQUITY ARN-1. Neither we nor any agent has independently verified the accuracy or completeness of any information with respect to the Index in connection with the offer and sale of the notes.

In addition, information about the Index may be obtained from other sources including, but not limited to, the Index Sponsor’s website. We are not incorporating by reference into this term sheet the website or any material it includes. Neither we nor any agent makes any representation that such publicly available information regarding the Index is accurate or complete.

The Index is calculated and published by STOXX and the euro price return version of the Index is reported by Bloomberg L.P. under the ticker symbol “SX5E.”

General

The Index is a free-float market capitalization weighted index composed of the largest stocks in terms of free-float market capitalization traded on the major exchanges of 11 Eurozone countries: Austria, Belgium, Finland, France, Germany, Ireland, Italy, Luxembourg, the Netherlands, Portugal and Spain. At any given time, some eligible countries may not be represented in the Index.

The Index is composed of all of the components of the STOXX ® Europe 600 Index that are traded in euros and assigned to countries in the Eurozone.

The weighting cap factor limits the weight of each component stock within the Index to a maximum of 20% of the Index at the time of each review.

Index Maintenance

The compo sition of each of the Index is reviewed quarterly in March, June, September and December. The review cut-off date is the last trading day of the month preceding the review month.

The composition of the Index is reviewed annually in September. The review cut-off date is the last trading day of August. The composition of the Index is also reviewed monthly and components that rank 75 or below are replaced and non-component stocks that rank 25 or above are added.

In addition, changes to country classification and listing are effective as of the next quarterly review. At that time, the Index is adjusted accordingly to remain consistent with its country membership rules by deleting the company where necessary.

The Index is also reviewed on an ongoing basis. Corporate actions (including initial public offerings, mergers and takeovers, spin-offs, delistings, bankruptcy, and price and share adjustments) that affect the Index composition are immediately reviewed. Any changes are announced, implemented and effective in line with the type of corporate action and the magnitude of the effect.

To maintain the number of components constant, a removed company is replaced by the highest-ranked non-component on the relevant selection list. The selection list is updated on a monthly basis according to the review component selection process.

The free-float factors for each component stock used to calculate the Index are reviewed, calculated and implemented on a quarterly basis and are fixed until the next quarterly review.

Index Calculation

The Index is calculated with the “Laspeyres formula,” which measures the aggregate price changes in the component stocks against a fixed base quantity weight. The formula for calculating the value of the Index can be expressed as follows:

Index =
divisor

The “free-float market capitalization of the Index” is equal to the sum of the products, for each component stock, of the price, number of shares, free-float factor, weighting cap factor and, if applicable, the exchange rate from the local currency into the index currency of the Index as of the time the Index is being calculated.

The free-float factor of each component stock is intended to reduce the number of shares to the actual amount available on the market. All fractions of the total number of shares that are larger than or equal to 5% and whose holding is of a long-term nature are excluded from the calculation of the Index, including: cross-ownership (stock owned either by the company itself, in the form of treasury shares, or owned by other companies); government ownership (stock owned by either governments or their agencies); private ownership (stock owned by either individuals or families); and restricted shares that cannot be traded during a certain period or have a foreign ownership restriction. Block ownership is not applied for holdings of custodian nominees, trustee companies, mutual funds, investment companies with short-term investment strategies, pension funds and similar entities.

The Index is also subject to a divisor, which is adjusted to maintain the continuity of the values of the Index despite changes due to corporate actions. The following is a summary of the adjustment s to any component stock of the Index made for corporate actions and the effect of such adjustment on the divisor of the Index, where shareholders of the component stock will receive “B” number of shares for every “A” share held (where applicable).

Rights Offering
If the subscription price is not available or equal to or greater than
the closing price on the day before the ex-date (out-of-the-money), then no adjustment is made. If the subscription price is available as a price range and not as a
fixed price, the price and share adjustment is performed only if both lower and upper range are in the money. The average value between
lower and upper range will be used as a subscription price.
Standard Rights Issue	Divisor

rights will be removed at the close of the day they start to trade based on its closing price. o If
the rights issue results into listing of new shares and satisfy certain criteria relating to free float factors and share adjustments

Supplement to the Plan of Distribution

Under our distribution agreement with BofAS, BofAS will purchase the notes from us as principal at the public offering price indicated on the cover of this term sheet, less the indicated underwriting discount.

BofAS has informed us of the information in the following paragraph. MLPF&S will purchase the notes from BofAS for resale, and will receive a selling concession in connection with the sale of the notes in an amount up to the full amount of underwriting discount set forth on the cover of this term sheet.

We will pay a fee to LFT Securities, LLC for providing certain electronic platform services with respect to this offering, which reduces the economic terms of the notes to you. An affiliate of BofAS has an ownership interest in LFT Securities, LLC.

We may deliver the notes against payment therefor in New York, New York on a date that is greater than one business day following the pricing date. Under Rule 15c6-1 of the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes more than one business day prior to the original issue date will be required to specify alternative settlement arrangements to prevent a failed settlement.

The notes will not be listed on any securities exchange. In the original offering of the notes, the notes will be sold in minimum investment amounts of 100 units. If you place an order to purchase the notes, you are consenting to MLPF&S and/or one of its affiliates acting as a principal in effecting the transaction for your account.

BofAS has advised us that MLPF&S and BofAS may repurchase and resell the notes, with repurchases and resales being made at prices related to then-prevailing market prices or at negotiated prices determined by reference to their pricing models at their discretion, and these prices will include MLPF&S’s and BofAS’s trading commissions and mark-ups or mark-downs. MLPF&S and BofAS may act as principal or agent in these market-making transactions; however, neither is obligated to engage in any such transactions. BofAS has advised us that at MLPF&S’s and BofAS’s discretion, for a short, undetermined initial period after the issuance of the notes, MLPF&S and BofAS may offer to buy the notes in the secondary market at a price that may exceed the initial estimated value of the notes. Any price offered by MLPF&S or BofAS for the notes is expected to be based on then-prevailing market conditions and other considerations, including the performance of the Index and the remaining term of the notes. However, none of us, MLPF&S, BofAS or any of our respective affiliates is obligated to purchase your notes at any price or at any time, and we cannot assure you that we, MLPF&S, BofAS or any of our respective affiliates will purchase your notes at a price that equals or exceeds the initial estimated value of the notes.

BofAS has informed us that, as of the date of this term sheet, it expects that if you hold your notes in a BofAS account, the value of the notes shown on your account statement will be based on BofAS’s estimate of the value of the notes if BofAS or another of its affiliates were to make a market in the notes, which it is not obligated to do. That estimate will be based upon the price that BofAS may pay for the notes in light of then-prevailing market conditions and other considerations, as mentioned above, and will include transaction costs. At certain times, this price may be higher than or lower than the initial estimated value of the notes.

The distribution of the Note Prospectus in connection with these offers or sales will be solely for the purpose of providing investors with the description of the terms of the notes that was made available to investors in connection with their initial offering. Secondary market investors should not, and will not be authorized to, rely on the Note Prospectus for information regarding BMO or for any purpose other than that described in the immediately preceding sentence.

Structuring the Notes

The notes are our debt securities, the return on which is linked to the performance of the Index. As is the case for all of our debt securities, including our market-linked notes, the economic terms of the notes reflect our actual or perceived creditworthiness at the time of pricing. In addition, because market-linked notes result in increased operational, funding and liability management costs to us, we typically borrow the funds under these notes at a rate that is more favorable to us than the rate which we refer to as our internal funding rate, which is the rate that we might pay for a conventional fixed or floating rate debt security. This generally relatively lower internal funding rate, which is reflected in the economic terms of the notes, along with costs associated with offering, structuring and hedging the notes, results in the initial estimated value of the notes on the pricing date being less than the public offering price.

At maturity, we are required to pay the Redemption Amount to holders of the notes, which will be calculated based on the $10 per unit principal amount and will depend on the performance of the Index. In order to meet these payment obligations, at the time we issue the notes, we expect to enter into certain hedging arrangements (which may include call options, put options or other derivatives) with BofAS or one of its affiliates. The terms of these hedging arrangements are determined by seeking bids from market participants, which may include MLPF&S, BofAS and/or one of their or our respective affiliates, and take into account a number of factors, including our creditworthiness, interest rate movements, the volatility of the Index, the tenor of the notes and the tenor of the hedging arrangements. The economic terms of the notes and their initial estimated value depend in part on the terms of these hedging arrangements.

BofAS has advised us that the hedging arrangements will include a hedging related charge of approximately $0.05 per unit, reflecting an estimated profit to be credited to BofAS from these transactions. Since hedging entails risk and may be influenced by unpredictable market forces, additional profits and losses from these hedging arrangements may be realized by our affiliates, MLPF&S, BofAS or any other hedge providers. Any profit in connection with such hedging activity will be in addition to any other compensation that the agent, and their or our respective affiliates receive for the sale of notes, which creates an additional incentive to sell the notes to you.

Summary of Canadian Federal Income Tax Consequences

For a discussion of the material Canadian federal income tax consequences relating to an investment in the notes, please see the section entitled “Canadian Federal Income Tax Summary” in the product supplement EQUITY ARN-1.

United States Federal Income Tax Considerations

Although there is uncertainty regarding the U.S. federal income tax consequences of an investment in the notes due to the lack of governing authority, in the opinion of our counsel Davis Polk & Wardwell LLP, under current law, and based on current market conditions, it is reasonable to treat a note as a single financial contract that is an “open transaction” for U.S. federal income tax purposes. Assuming this treatment of the notes is respected, the tax consequences are as outlined in the discussion under “United States Federal Income Tax Considerations—Tax Consequences to U.S. Holders—ARNs Treated as Open Transactions” in the accompanying product supplement.

We do not plan to request a ruling from the Internal Revenue Service (the “IRS”) regarding the treatment of the notes. If the IRS were successful in asserting an alternative treatment of the notes, the tax consequences of the ownership and disposition of the notes, including the timing and character of income recognized by U.S. investors, and the withholding tax consequences to non-U.S. investors, might be materially and adversely affected. For example, under one alternative characterization the notes may be treated as contingent payment debt instruments, which would require U.S. investors to accrue income periodically based on a “comparable yield” and generally would require non-U.S. investors to certify their non-U.S. status on an IRS Form W-8 to avoid a 30% (or a lower treaty rate) U.S. withholding tax. In addition, the U.S. Treasury Department and the IRS have requested comments on various issues regarding the U.S. federal income tax treatment of “prepaid forward contracts” and similar financial instruments and have indicated that such transactions may be the subject of future regulations or other guidance. Furthermore, members of Congress have proposed legislative changes to the tax treatment of derivative contracts. Any legislation, Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the notes, possibly with retroactive effect.

As discussed in the accompanying product supplement, Section 871(m) of the Code and the Treasury regulations thereunder (“Section 871(m)”) generally impose a 30% (or lower treaty rate) withholding tax on “dividend equivalents” paid or deemed paid to non-U.S. investors with respect to certain financial instruments linked to equities that could pay U.S.-source dividends for U.S. federal income tax purposes (“underlying securities”), as defined under the applicable Treasury regulations, or indices that include underlying securities. Section 871(m) generally applies to financial instruments that substantially replicate the economic performance of one or more underlying securities, as determined based on tests set forth in the applicable Treasury regulations. Pursuant to an IRS notice, Section 871(m) will not apply to notes issued before January 1, 2027 that do not have a delta of one with respect to any underlying security. Based on our determination that the notes do not have a delta of one with respect to any underlying security, the notes should not be subject to Section 871(m). Our determination is not binding on the IRS, and the IRS may disagree with this determination. Section 871(m) is complex and its application may depend on a non-U.S. investor’s particular circumstances, including whether the non-U.S. investor enters into other transactions with respect to an underlying security. If withholding is required, we will not be required to pay any additional amounts with respect to the amounts so withheld. Non-U.S. investors should consult their tax advisors regarding the potential application of Section 871(m) to the notes.

Both U.S. and non-U.S. investors considering an investment in the notes should read the discussion under “United States Federal Income Tax Considerations” in the accompanying product supplement and consult their tax advisors regarding all aspects of the U.S. federal income and estate tax consequences of an investment in the notes, including possible alternative treatments, and any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

Insofar as the foregoing opinion involves matters governed by the laws of the Provinces of Ontario and Québec and the federal laws of Canada, you have received, and we understand that you are relying upon, the opinion of Osler, Hoskin & Harcourt LLP, Canadian counsel for the Bank of Montreal, set forth above.
