TABLE OF CONTENTS

S-i

ABOUT THIS PROSPECTUS SUPPLEMENT

This prospectus supplement and the accompanying prospectus and, if applicable, a product supplement and/or an underlying supplement, provide you with a general description of the notes we may offer. Each time we sell notes we will provide a pricing supplement containing specific information about the terms of the notes being offered. Each pricing supplement may include a discussion of any risk factors or other special considerations that apply to those notes. The pricing supplement may also add, update or change the information in this prospectus supplement and any applicable product supplement and/or underlying supplement. If there is any inconsistency between the information in this prospectus supplement, any applicable product supplement and/or underlying supplement and any pricing supplement, you should rely on the information in that pricing supplement.

In this prospectus supplement, the “Bank,” “CIBC,” “we,” “us” and “our” refer to Canadian Imperial Bank of Commerce, unless the context requires otherwise.

RISK FACTORS

An investment in the notes is subject to the risks described below, as well as the risks described under “Risk Factors” in the accompanying prospectus and the risks identified and discussed in the management’s discussion and analysis of financial condition and results of operations included in our Annual Report on Form 40-F for the fiscal year ended October 31, 2025 and subsequent reports. You should carefully consider whether the notes are suited to your particular circumstances. This prospectus supplement should be read together with the accompanying prospectus and the relevant pricing supplement. The information in the accompanying prospectus is supplemented by, and to the extent inconsistent therewith replaced and superseded by, the information in this prospectus supplement and the relevant pricing supplement. This section describes the most significant risks relating to the notes. We urge you to read the following information about these risks, together with the other information in this prospectus supplement, the accompanying prospectus, the documents incorporated by reference therein, and the relevant pricing supplement, before investing in the notes.

Structure Risks

The Notes May Not Be Conventional Debt Securities

The notes may not be conventional debt securities. If specified in the relevant pricing supplement, the notes may provide no assurance that any of the principal amount of the notes will be paid at or before maturity. In addition, the notes may not provide holders with a return or income stream prior to maturity calculated by reference to a fixed or floating rate of interest determinable prior to maturity. The notes, unlike traditional debt obligations, may be speculative or uncertain in that they could produce no return on a holder’s original investment or not repay any principal amount at or before maturity. Prospective purchasers are directed to the relevant pricing supplement for the specific terms of the relevant notes, including any risk factors set out therein.

The Notes Are Not Covered By Deposit Insurance

The notes will not constitute savings accounts, deposits or other obligations that are insured by the Federal Deposit Insurance Corporation, the Deposit Insurance Fund or any other governmental agency or under the CDIC Act, the Bank Act (Canada) (the “Bank Act”), or any other deposit insurance regime designed to ensure the payment of all or a portion of a deposit upon the insolvency of the deposit taking financial institution. Therefore, you will not be entitled to insurance from the Federal Deposit Insurance Corporation or the Canada Deposit Insurance Corporation (the “CDIC”) or other such protection, and as a result, you could lose all or a portion of your investment.

The Notes Are Structurally Subordinated to the Liabilities of Our Subsidiaries

If we become insolvent, the Bank Act provides that priorities among payments of our deposit liabilities and payments of all of our other liabilities (including payments in respect of the notes) are to be determined in accordance with the laws governing priorities and, where applicable, by the terms of the indebtedness and liabilities. Because we have subsidiaries, our right to participate in any distribution of the assets of our banking or non-banking subsidiaries, upon a subsidiary's dissolution, winding-up, liquidation or reorganization or otherwise, and thus your ability to benefit indirectly from such distribution, is subject to the prior claims of creditors of that subsidiary, except to the extent that we may be a creditor of that subsidiary and our claims are recognized. In addition, there are regulatory and other legal limitations on the extent to which some of our subsidiaries may extend credit, pay dividends or otherwise supply funds to, or engage in transactions with, us or some of our other subsidiaries.

S-1

Accordingly, the notes will be structurally subordinated to all existing and future liabilities of our subsidiaries, and holders of the notes should look only to our assets and not those of our subsidiaries for payments on the notes.

The Notes May Be Subject to Risks Related to Canadian Usury Laws

The Criminal Code (Canada) prohibits the receipt of “interest” at a “criminal rate” (namely, an annual percentage rate of interest exceeding 35%). Accordingly, the provisions for the payment of interest or for the payment of a redemption amount in excess of the aggregate principal amount of the notes may not be enforceable if the provision provides for the payment of “interest” (as calculated for the purposes of such statute) which is in excess of an annual percentage rate exceeding 35%. If any notes are found not to be enforceable in whole or in part as a result of such prohibition, holders of the notes may not be able to collect some or all of the interest owing on such notes.

Credit Risks

An Investment in the Notes Is Subject to Our Credit Risk

Any payment to be made on the notes depends on our ability to pay all amounts when they become due. Therefore, an investment in any of the notes issued under our medium-term note program is subject to our credit risk. The existence of a trading market for, and the market value of, the notes may be impacted by market perception of our creditworthiness. If market perception of our creditworthiness were to decline for any reason, the market value of your notes, and availability of the trading markets generally, may be adversely affected.

If Your Notes Are Rated, the Rating Is Not a Guarantee of Our Credit Quality

Certain of your notes may be rated by credit rating agencies, although we are under no obligation to ensure that the notes are rated by any credit rating agency. Credit ratings may not reflect the potential impact of all risks related to structure, market, additional factors discussed in this “Risk Factors” section and other factors that may affect the liquidity or trading value of the notes. Investors should be aware that any rating of us reflects the independent opinion of the relevant rating agency and is not a guarantee of our credit quality. A credit rating is not a recommendation to buy, sell or hold securities and may be revised, suspended or withdrawn by the credit rating agency at any time.

Changes in Laws and Regulations, Including How They are Interpreted and Enforced in Applicable Jurisdictions, Could Have an Impact on Holders of the Notes

The financial services industry is highly regulated, and we have experienced changes and increased complexity in regulatory requirements as governments and regulators around the world continue major reforms intended to strengthen the stability of the financial system and protect key markets and participants. As a result, there is the potential for higher capital requirements and increased regulatory and compliance costs which could lower our returns and affect our growth. Failure to comply with applicable legal and regulatory requirements may result in litigation, financial losses, regulatory sanctions, enforcement actions, an inability to execute our business strategies, a decline in investor and customer confidence and harm to our reputation.

Liquidity Risks

There May Be No Market Through Which the Notes May Be Sold, and Holders May Not Be Able to Sell the Notes

Unless otherwise specified in the relevant pricing supplement, there may be no market through which the notes may be sold, and holders may not be able to sell the notes. This may affect the pricing of the notes in the secondary market, the transparency and availability of trading prices and the liquidity of the notes. Even if a secondary market for the notes develops, it may not provide significant liquidity or trade at prices advantageous to you. We expect that transaction costs in any secondary market would be high. As a result, the difference between bid and asked prices for your notes in any secondary market could be substantial.

If you are able to sell your notes before maturity, you may have to do so at a substantial discount from the issue price, and as a result, you may suffer substantial losses.

S-2

U.S. Tax Risks

U.S. Foreign Account Tax Compliance Act Withholding May Affect Payments on the Notes

The Foreign Account Tax Compliance Act provisions of the U.S. Internal Revenue Code of 1986, as amended (“FATCA”) may require U.S. tax withholding on certain payments made to custodians or intermediaries in the payment chain leading to the ultimate investor if any such custodian or intermediary generally is unable to receive payments free of FATCA withholding.  It also may affect payment to any ultimate investor that is a financial institution that is not entitled to receive payments free of withholding under FATCA, or an ultimate investor that fails to provide its broker (or other custodian or intermediary from which it receives payment) with any information, forms, other documentation or consents that may be necessary for the payments to be made free of FATCA withholding.  Investors should choose the custodians or intermediaries with care (to ensure each is compliant with FATCA or other laws or agreements related to FATCA) and provide each custodian or intermediary with any information, forms, other documentation or consents that may be necessary for such custodian or intermediary to make a payment free of FATCA withholding. Investors should consult their own tax adviser to obtain a more detailed explanation of FATCA and how FATCA may affect them.  The Bank’s obligations under the notes are discharged once it has made payment to, or to the order of, the common depositary or common safekeeper for the clearing systems (as bearer or registered holder of the notes) and the Bank has therefore no responsibility for any amount thereafter transmitted through the clearing systems and custodians or intermediaries.

Risks Relating to Indexed Notes

We use the term “indexed notes” to mean notes whose value is linked to an underlying asset or index. Indexed notes may present a high level of risk, and those who invest in indexed notes may lose all or a portion of their investment and may receive no interest on their investment. Indexed notes are complex and involve risks not associated with an investment in ordinary debt securities. You should thoroughly review each of an indexed note’s offering documents for a comprehensive description of the risks associated with the offering of such notes. In addition, the treatment of indexed notes for U.S. federal income tax purposes is often unclear due to the absence of any authority specifically addressing the issues presented by any particular indexed note.

Moreover, interest in respect of an indexed note, or any portion of the principal amount of an indexed note in excess of its issue price, may be subject to Canadian non-resident withholding tax.  We or the applicable paying agent will deduct or withhold from a payment on a note any Canadian non-resident withholding tax exigible and will not pay any additional amounts to offset such deduction or withholding unless otherwise specified in the relevant pricing supplement. Thus, if you propose to invest in indexed notes, you should independently evaluate the U.S. and Canadian federal income tax consequences of purchasing an indexed note that apply in your particular circumstances. See “Material Income Tax Consequences” in the accompanying prospectus for a discussion of the material U.S. and Canadian federal income tax considerations generally applicable to an investment in the notes.

Structure Risks

Investors in Indexed Notes Could Lose Their Investment

The amount of any principal and/or interest payable on an indexed note and the cash and/or physical settlement value will be determined by reference to the price, value or level of one or more securities, currencies, commodities, indices, exchange traded funds or other properties, any other financial, economic or other measure or instrument, including the occurrence or non-occurrence of any event or circumstance, and/or one or more indices or baskets of any of these items. We refer to each of these as an “index.” The direction and magnitude of the change in the price, value or level of the relevant index will determine the amount of any principal and/or interest payable on an indexed note, and the cash and/or physical settlement value of an indexed note. The terms of a particular indexed note may or may not provide a fixed return of a percentage of the principal amount at maturity or a minimum interest rate. Thus, if you purchase a particular indexed note that does not provide a fixed return of the principal amount or other amount, you may lose all or a portion of the principal or other amount you invest and may receive no interest on your investment.

S-3

The Return on Indexed Notes May Be Less Than the Return on Notes With a Similar Term That Are Not Indexed

Depending on the terms of an indexed note, as specified in the relevant pricing supplement, you may not receive any periodic interest payments or you may receive only very low payments on such indexed note. As a result, the overall return on such indexed note may be less, and possibly significantly less, than the amount you would have earned by investing the principal or other amount you invest in such indexed note in a non-indexed debt security that bears interest at a prevailing market fixed or floating rate.

Index Risks

The Issuer of a Security or Currency That Comprises an Index Could Take Actions That May Adversely Affect an Indexed Note

The issuer of a security that comprises an index or part of an index for an indexed note will have no involvement in the offer and sale of the indexed note and no obligations to the holder of the indexed note. Such an issuer may take actions, such as a merger or sale of assets, without regard to the interests of the holder of the indexed note. Any of these actions could adversely affect the value of a note indexed to that security or to an index of which that security is a component.

If the index for an indexed note includes a non-U.S. dollar currency or other asset denominated in a non-U.S. dollar currency, the government that issues that currency will also have no involvement in the offer and sale of the indexed note and no obligations to the holder of the indexed note. That government may take actions that could adversely affect the value of the note. See “Risks Relating to Notes Denominated or Payable in or Linked to a Non-U.S. Dollar Currency” below for more information about these kinds of government actions.

Investors in Indexed Notes Will Have No Ownership of the Underlying Assets

Investing in an indexed note will not entitle a holder to any direct or indirect ownership or entitlement to the underlying assets, except as specified in the relevant pricing supplement. A holder will not be entitled to the rights and benefits of a holder of the underlying assets, including any right to receive any underlying assets, any distributions or dividends on the underlying assets, or to vote at or attend any meetings of holders of the underlying assets.

An Indexed Note May Be Linked to a Volatile Index, Which Could Hurt the Return on Your Investment

Some indices are highly volatile, which means that their value may change significantly, up or down, over a short period of time. The amount of any principal and/or interest that can be expected to become payable on an indexed note may vary substantially from time to time. Because the amounts payable with respect to an indexed note are generally calculated based on the price, value or level of the relevant index on a specified date or over a limited period of time, volatility in the index increases the risk that the return on the indexed note may be adversely affected by a fluctuation in the level of the relevant index. The volatility of an index may be affected by political or economic events, including governmental actions, or by the activities of participants in the relevant markets. Any of these events or activities could adversely affect the value of an indexed note.

An Index to Which a Note Is Linked Could Be Changed or Become Unavailable

Some indices sponsored by us or our affiliates or third parties may consist of or refer to several or many different securities, commodities or currencies or other instruments or measures. The sponsor of such an index typically reserves the right to alter the composition of the index and the manner in which the value or level of the index is calculated. An alteration in an index to which a note is linked may result in a decrease in the value of or return on the indexed note. The indices for our indexed notes may include published indices of this kind or customized indices developed by us or our affiliates in connection with particular issues of indexed notes.

A published index may become unavailable, or a customized index may become impossible to calculate in the normal manner, due to events such as war, natural disasters, cessation of publication of the index, a suspension or disruption of trading in one or more index constituents or any other market disruption event described in the relevant pricing supplement. If an index becomes unavailable or impossible to calculate in the normal manner, the terms of a particular indexed note may allow us to delay determining the amount payable as principal or premium or interest on an indexed note, or we may use an alternative method to determine the value of the unavailable index. Alternative methods of valuation are generally intended to produce a value similar to the value resulting from

S-4

reference to the relevant index. However, it is unlikely that any alternative method of valuation we use will produce a value identical to the value that the actual index would have produced. If we use an alternative method of valuation for a note linked to an index of this kind, the value of the note, or the rate of return on it, may be lower than it otherwise would be.

Some indexed notes are linked to indices that are not commonly used or that have been developed only recently. The lack of a trading history may make it difficult to anticipate the volatility or other risks associated with an indexed note of this kind. In addition, trading in these indices or their index constituents, or options or futures contracts on these indices or index constituents, may be limited, which could increase their volatility and decrease the value of the related indexed notes or the rates of return on them.

Pricing Information About the Assets Underlying a Relevant Index May Not Be Available Due to Time Zone Differences

Special risks may also be presented because of differences in time zones between the United States and the market for the assets underlying the relevant index, such that the underlying assets are traded on a foreign exchange that is not open when the trading market for the notes in the United States, if any, is open or where trading occurs in the underlying assets during times when the trading market for the notes in the United States, if any, is closed. In such cases, holders of the notes may have to make investment decisions at a time when current pricing information regarding the assets underlying the relevant index is not available.

Information About Indices May Not Be Indicative of Future Performance

If we issue an indexed note, we may include historical information about the relevant index in the relevant pricing supplement. Any information about indices that we may provide will be furnished as a matter of information only, and you should not regard the information as indicative of the range of, or trends in, fluctuations in the relevant index that may occur in the future or indicative of any payment of principal or interest to be paid on the indexed notes.

Conflicts of Interest

We May Engage in Hedging Activities That Could Adversely Affect an Indexed Note

In order to hedge an exposure on a particular indexed note, we may, directly or through our affiliates or other agents, enter into transactions involving the index constituents, or involving derivative instruments, such as swaps, options or futures, on the index or any of its component items. To the extent that we enter into hedging arrangements with a non-affiliate, including a non-affiliate agent, such non-affiliate may enter into similar transactions. Engaging in transactions of this kind could adversely affect the value of an indexed note. It is possible that we or a hedging counterparty could achieve substantial returns from our hedging transactions while the value of the indexed note may decline. However, none of us, any of our affiliates or any other agents will be obliged to hedge our exposure under an indexed note. There can be no assurance that any hedging transaction will be maintained or successful.

We May Have Conflicts of Interest Regarding an Indexed Note

CIBCWM and our other affiliates and unaffiliated agents may have conflicts of interest with respect to some indexed notes. CIBCWM and our other affiliates and unaffiliated agents may engage in trading, including trading for hedging purposes, for their proprietary accounts or for other accounts under their management, in indexed notes and in the index constituents or in other derivative instruments related to the index or its component items. These trading activities could adversely affect the value of indexed notes. We and our affiliates and unaffiliated agents may also issue or underwrite securities or derivative instruments that are linked to the same index as one or more indexed notes. Introducing competing products into the marketplace in this manner could adversely affect the value of a particular indexed note.

CIBCWM or another of our affiliates or an unaffiliated entity that provides us a hedge in respect of indexed notes may serve as calculation agent and/or exchange rate agent for the indexed notes and may have considerable discretion in calculating the amounts payable in respect of the notes. To the extent that CIBCWM or another of our affiliates or such an unaffiliated entity sponsors, calculates or compiles a particular index, it may also have considerable discretion in performing the calculation or compilation of the index. For example, it may be permitted to change the methodology of the index or discontinue the publication of the index. Exercising discretion in this manner could adversely affect the value of an indexed note based on the index or the rate of return on the note.

S-5

Risks Relating to Floating Rate Notes

Structure Risks

Floating Rates of Interest Are Uncertain and Could Be 0.0%

If your notes are floating rate notes or otherwise directly linked to a floating rate for some portion of the notes’ term, no interest will accrue on the notes with respect to any interest period for which the applicable floating rate specified in the relevant pricing supplement is zero on the related interest rate reset date. Floating interest rates, by their very nature, fluctuate, and may be as low as 0.0%. Also, in certain economic environments, floating rates of interest may be less than fixed rates of interest for instruments with a similar credit quality and term. As a result, the return you receive on your notes may be less than a fixed rate security issued for a similar term by a comparable issuer. Even if your return on the notes is positive, and even if your notes have a specified fixed rate of interest for one or more interest periods, the return on your investment may not compensate you for the opportunity cost when you take into account factors, such as inflation, that affect the time value of money.

Risks for EURIBOR

Notes That Bear Interest at Rates Based on EURIBOR May Be Adversely Affected By Changes in Our EURIBOR Reporting Practices or the Method in Which EURIBOR is Determined or Circumstances Where EURIBOR is No Longer Determined or Published

The European Money Markets Institute (formerly Euribor-EBF) has continued in its role as administrator of EURIBOR but has also undertaken a number of reforms in relation to its governance and technical framework since January 2013 pursuant to recommendations by the European Securities and Markets Authority and the European Banking Authority.

It is not possible to predict any changes in the methods pursuant to which the EURIBOR rates are determined, or any other reforms to EURIBOR or any other relevant benchmarks that will be enacted in the European Union (the “EU”) and elsewhere, each of which may adversely affect the trading market for securities based on EURIBOR or any other relevant benchmark, including any notes that bear interest at rates based on EURIBOR and may cause such benchmarks to perform differently than in the past, or cease to exist. In addition, any legal or regulatory changes made by the European Money Markets Institute, the European Commission or any other successor governance or oversight body, or future changes adopted by such body, in the method pursuant to which the EURIBOR or any other relevant benchmarks are determined may result in, among other things, a sudden or prolonged increase or decrease in the reported benchmark, a delay in the publication of any such benchmark rates, trigger changes in the rules or methodologies in certain benchmarks discouraging market participants from continuing to administer or to participate in certain benchmarks, and, in certain situations, could result in a benchmark rate no longer being determined and published. Accordingly, in respect of a note referencing EURIBOR or any other relevant benchmark, such proposals for reform and changes in applicable regulation could have a material adverse effect on the trading market for, the value of and return on such a note (including potential rates of interest thereon).

Risks for SOFR

The Secured Overnight Financing Rate Is a Relatively New Reference Rate and its Composition and Characteristics Are Not the Same as the London Inter-Bank Offered Rate (“LIBOR”)

On June 22, 2017, the Alternative Reference Rates Committee (“ARRC”) convened by the Board of Governors of the Federal Reserve System and the Federal Reserve Bank of New York identified the Secured Overnight Financing Rate (“SOFR”) as the rate that, in the consensus view of the ARRC, represented best practice for use in certain new U.S. dollar derivatives and other financial contracts. SOFR is a broad measure of the cost of borrowing cash overnight collateralized by U.S. Treasury securities, and has been published by the Federal Reserve Bank of New York since April 2018. The Federal Reserve Bank of New York has also been publishing historical indicative Secured Overnight Financing Rates from 2014. Investors should not rely on any historical changes or trends in SOFR as an indicator of future changes in SOFR (whether based on actual or indicative historical data). The future performance of SOFR cannot be predicted based on its past performance, and the level of SOFR during the term of the notes may bear little or no relation to the historical performance of SOFR.

The composition and characteristics of SOFR are not the same as those of LIBOR, and SOFR is fundamentally different from LIBOR for two key reasons. First, SOFR is a secured rate, while LIBOR is an

S-6

unsecured rate. Second, SOFR is an overnight rate, while LIBOR is a forward-looking rate that represents interbank funding over different maturities (e.g., three months). As a result, there can be no assurance that SOFR (including Compounded SOFR) will perform in the same way as LIBOR would have at any time, including, without limitation, as a result of changes in interest and yield rates in the market, market volatility or global or regional economic, financial, political, regulatory, judicial or other events.

SOFR May Be More Volatile than Other Benchmark or Market Rates

Since the initial publication of SOFR, daily changes in SOFR have, on occasion, been more volatile than daily changes in other benchmark or market rates during corresponding periods. Although changes in Compounded SOFR generally are not expected to be as volatile as changes in daily levels of SOFR, the return on and value of SOFR-linked notes may fluctuate more than floating rate securities that are linked to less volatile rates. In addition, the volatility of SOFR has reflected the underlying volatility of the overnight U.S. Treasury repo market. The Federal Reserve Bank of New York has at times conducted operations in the overnight U.S. Treasury repo market in order to help maintain the federal funds rate within a target range. There can be no assurance that the Federal Reserve Bank of New York will continue to conduct such operations in the future, and the duration and extent of any such operations is inherently uncertain. The effect of any such operations, or of the cessation of such operations to the extent they are commenced, is uncertain, could be materially adverse to investors in a note linked to the Compounded SOFR or the SOFR Index, and could adversely affect the price at which investors can sell SOFR-linked notes.

Any Failure of SOFR to Gain Market Acceptance Could Adversely Affect Notes Linked to SOFR

According to the ARRC, SOFR was developed for use in certain U.S. dollar derivatives and other financial contracts as an alternative to USD LIBOR in part because it is considered a good representation of general funding conditions in the overnight U.S. Treasury repurchase agreement market. However, as a rate based on transactions secured by U.S. Treasury securities, it does not measure bank-specific credit risk and, as a result, is less likely to correlate with the unsecured short-term funding costs of banks. This may mean that market participants would not consider SOFR a suitable replacement or successor for all of the purposes for which USD LIBOR historically had been used (including, without limitation, as a representation of the unsecured short-term funding costs of banks), which may, in turn, lessen market acceptance of SOFR. Any failure of SOFR to gain market acceptance could adversely affect the return on and value of a note linked to SOFR and the price at which investors can sell such notes in the secondary market.

In addition, if SOFR fails to be widely used as a benchmark in securities that are similar or comparable to your SOFR-linked notes, the trading price of the notes may be lower than those of securities that are linked to rates that are more widely used. Similarly, market terms for floating-rate debt securities linked to SOFR may evolve over time, and trading prices of the notes may be lower than those of later-issued SOFR-based debt securities as a result. Investors in a note linked to SOFR may not be able to sell such notes at all or may not be able to sell such notes at prices that will provide them with a yield comparable to similar investments that have a developed secondary market, and may consequently suffer from increased pricing volatility and market risk.

SOFR May be Modified or Discontinued and Notes Linked to SOFR May Bear Interest by Reference to a Rate Other than SOFR, which Could Adversely Affect the Value of such Notes

SOFR is published by the Federal Reserve Bank of New York based on data received by it from sources other than us, and we have no control over its methods of calculation, publication schedule, rate revision practices or availability of SOFR at any time. There can be no guarantee, particularly given its relatively recent introduction, that SOFR will not be discontinued or fundamentally altered in a manner that is materially adverse to the interests of investors in notes linked to SOFR. If the manner in which SOFR is calculated is changed or, if applicable, if the manner in which the Compounded SOFR or SOFR Index is calculated is changed, that change may result in a reduction in the amount of interest payable on notes linked to SOFR and the trading prices of such notes. In addition, the Federal Reserve Bank of New York may withdraw, modify, amend, suspend or discontinue the calculation or dissemination of SOFR data in its sole discretion and without notice and has no obligation to consider the interests of holders of SOFR-linked notes in calculating, withdrawing, modifying, amending, suspending or discontinuing SOFR. The interest rate for any interest period will not be adjusted for any modifications or amendments to SOFR or SOFR data that the Federal Reserve Bank of New York may publish after the interest rate for that interest period has been determined.

If we or the calculation agent determines that a Benchmark Transition Event and its related Benchmark Replacement Date, each as defined in “Description of the Notes We May Offer—Interest Rates—SOFR Notes,” have

S-7

occurred in respect of SOFR, then the interest rate on notes linked to SOFR will no longer be determined by reference to SOFR, but instead will be determined by reference to a different rate, plus a spread adjustment, which we refer to as a “Benchmark Replacement,” as further described under the caption “Description of the Notes We May Offer—Interest Rates—SOFR Notes.”

If a particular Benchmark Replacement or Benchmark Replacement Adjustment, each as defined in Description of the Notes We May Offer—Interest Rates—SOFR Notes, cannot be determined, then the next-available Benchmark Replacement or Benchmark Replacement Adjustment will apply. These replacement rates and adjustments may be selected, recommended or formulated by (i) the Relevant Governmental Body (as defined herein) (such as the ARRC), (ii) the International Swaps and Derivatives Association (“ISDA”) or (iii) in certain circumstances, us or the calculation agent. In addition, the terms of the notes may expressly authorize us or the calculation agent to make Benchmark Replacement Conforming Changes, as defined in “Description of the Notes We May Offer—Interest Rates—SOFR Notes,” with respect to, among other things, interest periods, the timing and frequency of determining rates and making payments of interest and other administrative matters. The determination of a Benchmark Replacement, the calculation of the interest rate on the notes linked to SOFR by reference to a Benchmark Replacement (including the application of a Benchmark Replacement Adjustment), any implementation of Benchmark Replacement Conforming Changes and any other determinations, decisions or elections that may be made under the terms of such notes in connection with a Benchmark Transition Event, which may potentially be subjective, could adversely affect the value of such notes, the return on such notes and the price at which you can sell such notes.

In addition, (i) the composition and characteristics of the Benchmark Replacement will not be the same as those of SOFR, the Benchmark Replacement may not be the economic equivalent of SOFR, there can be no assurance that the Benchmark Replacement will perform in the same way as SOFR would have at any time and there is no guarantee that the Benchmark Replacement will be a comparable substitute for SOFR (each of which means that a Benchmark Transition Event could adversely affect the value of notes linked to SOFR, the return on such notes and the price at which you can sell such notes), (ii) any failure of the Benchmark Replacement to gain market acceptance could adversely affect notes linked to SOFR, (iii) the Benchmark Replacement may have a very limited history and the future performance of the Benchmark Replacement may not be predicted based on historical performance, (iv) the secondary trading market for notes linked to the Benchmark Replacement may be limited and (v) the administrator of the Benchmark Replacement may make changes that could change the value of the Benchmark Replacement or discontinue the Benchmark Replacement and has no obligation to consider your interests in doing so.

The Interest Rate on SOFR-Linked Notes May Be Based on a Compounded SOFR or the SOFR Index, Which is Relatively New in the Marketplace

For each interest period, the interest rate on floating-rate debt securities linked to SOFR may be based on a Compounded SOFR, which is calculated using the SOFR Index (as defined herein) published by the Federal Reserve Bank of New York according to the specific formula described under “Description of the Notes We May Offer—Interest Rates—SOFR Notes”, rather than the SOFR rate published on or in respect of a particular date during such interest period or an arithmetic average of SOFR rates during such period. For this and other reasons, the interest rate on a note linked to the Compounded SOFR or SOFR Index during any interest period will not necessarily be the same as the interest rate on other SOFR-linked investments that use an alternative basis to determine the applicable interest rate. Further, if the interest rate is based on a Compounded SOFR and the SOFR rate in respect of a particular date during an interest period is negative, its contribution to the SOFR Index will be less than one, resulting in a reduction to the Compounded SOFR used to calculate the interest payable on notes linked to the Compounded SOFR on the interest payment date for such interest period.

The Compounded SOFR with Respect to a Particular Interest Period Will Only be Capable of Being Determined Near the End of the Relevant Interest Period

If the interest rate on your notes is based on a Compounded SOFR, the level of the Compounded SOFR applicable to a particular interest period, as defined below under “Description of the Notes We May Offer—Interest,” and, therefore, the amount of interest payable with respect to such interest period will be determined on the interest determination date, as defined below under “Description of the Notes We May Offer—Interest Rates—SOFR Notes,” for such interest period. Because each such date is near the end of such interest period, you will not know the amount of interest payable with respect to a particular interest period until shortly prior to the related interest payment date and it may be difficult for you to reliably estimate the amount of interest that will be payable on each

S-8

such interest payment date. In addition, some investors may be unwilling or unable to trade notes linked to the Compounded SOFR or SOFR Index without changes to their information technology systems, both of which could adversely impact the liquidity and trading price of notes linked to the Compounded SOFR or SOFR Index.

The Compounded SOFR for an Interest Period During a Floating-Rate Period May Not Reflect Any Subsequently Published Corrections to SOFR

The Federal Reserve Bank of New York publishes SOFR each U.S. Government Securities Business Day at approximately 8:00 a.m. (New York time) for trades made on the immediately preceding U.S. Government Securities Business Day. After publication, if (i) the Federal Reserve Bank of New York discovers errors in the transaction data or calculation process or additional transaction data becomes available and (ii) such errors or additional data would change the published SOFR by at least one basis point (0.01%), subject to change based on periodic review by the Federal Reserve Bank of New York, then the Federal Reserve Bank of New York will republish SOFR at approximately 2:30 p.m. (New York time) on that same day. The Federal Reserve Bank of New York will not revise published SOFR on any U.S. Government Securities Business Day after the original date of publication and, even if the Federal Reserve Bank of New York’s policy changes to permit revisions to SOFR after the initial publication date, such changes would not be reflected in the calculation agent’s determination of Compounded SOFR on a U.S. Government Securities Business Day under the notes because such determination is made as of 3:00 p.m. (New York time) on each U.S. Government Securities Business Day without regard to any subsequently published revisions.

Conflicts of Interest

The Calculation Agent Will Make Determinations with Respect to Floating Rate Notes

We or any affiliate of ours, such as CIBCWM, will serve as the calculation agent; however, we may change the calculation agent at any time without notice to holders. The calculation agent will make certain determinations with respect to the floating rate notes as further described under the caption “Description of the Notes We May Offer.” In addition, if a Benchmark Transition Event and its related Benchmark Replacement Date have occurred or if any of the commercial paper rate, U.S. prime rate, treasury rate, CMT rate or federal funds rate have been discontinued, the calculation agent will make certain determinations with respect to our floating rate notes in the calculation agent’s sole discretion as further described under the caption “Description of the Notes We May Offer — Interest Rates — Floating Rate Notes.” Any determination, decision or election pursuant to the benchmark replacement provisions not made by the calculation agent will be made by us. Any of these determinations may adversely affect the value of the floating rate notes, the return on the floating rate notes and the price at which you can sell such floating rate notes. Moreover, certain determinations may require the exercise of discretion and the making of subjective judgments, such as with respect to Compounded SOFR or the occurrence or non-occurrence of a Benchmark Transition Event and any Benchmark Replacement Conforming Changes. The exercise of this discretion by the calculation agent may also present us with a conflict of interest. For further information regarding these types of determinations, see “Description of the Notes We May Offer — Interest Rates — Floating Rate Notes.”

Risks Relating to Notes Denominated or Payable in or Linked to a Non-U.S. Dollar Currency

If you intend to invest in a non-U.S. dollar note — e.g., a note whose principal and/or interest is payable in a currency other than U.S. dollars or that may be settled by delivery of or reference to a non-U.S. dollar currency or property (if so indicated in the relevant pricing supplement) denominated in or otherwise linked to a non-U.S. dollar currency  — you should consult your own financial, legal and tax advisors as to the currency risks entailed by your investment. Notes of this kind may not be an appropriate investment for investors who are unsophisticated with respect to non-U.S. dollar currency transactions. The information in this prospectus supplement is directed primarily at investors who are U.S. residents. Investors who are non-U.S. residents should consult their own financial, legal and tax advisors about currency-related risks particular to their investment in the notes.

An Investment in a Non-U.S. Dollar Note Involves Currency-Related Risks

An investment in a non-U.S. dollar note entails significant risks that are not associated with a similar investment in a note that is payable solely in U.S. dollars and where settlement value is not otherwise based on a non-U.S. dollar currency. These risks include the possibility of significant changes in rates of exchange between the U.S. dollar and the various non-U.S. dollar currencies or composite currencies and the possibility of the imposition or modification of foreign exchange controls or other conditions by either the United States or non-U.S.

S-9

governments. These risks generally depend on factors over which we have no control, such as economic and political events and the supply of and demand for the relevant currencies in the global markets.

Changes in Currency Exchange Rates Can Be Volatile and Unpredictable

Rates of exchange between the U.S. dollar and many other currencies have been highly volatile, and this volatility may continue and perhaps spread to other currencies in the future. Fluctuations in currency exchange rates could adversely affect an investment in a note denominated in, or where value is otherwise linked to, a specified currency other than U.S. dollars. Depreciation of the specified currency against the U.S. dollar could result in a decrease in the U.S. dollar-equivalent value of payments on the note, including the principal payable at maturity. That in turn could cause the market value of the note to fall. Depreciation of the specified currency against the U.S. dollar could result in a loss to the investor on a U.S. dollar basis.

We Will Not Adjust Non-U.S. Dollar Notes to Compensate for Changes in Currency Exchange Rates

Except as described above or in the relevant pricing supplement, we will not make any adjustment or change in the terms of a non-U.S. dollar note in the event of any change in exchange rates for the relevant currency, whether in the event of any devaluation, revaluation or imposition of exchange or other regulatory controls or taxes or in the event of other developments affecting that currency, the U.S. dollar or any other currency. Consequently, investors in non-U.S. dollar notes will bear the risk that their investment may be adversely affected by these types of events.

Government Policy Can Adversely Affect Foreign Currency Exchange Rates and the Return on an Investment in a Non-U.S. Dollar Note

Foreign currency exchange rates can either float or be fixed by sovereign governments. From time to time, governments use a variety of techniques, such as intervention by a country’s central bank or imposition of regulatory controls or taxes, to affect the exchange rate of their currencies. Governments may also issue a new currency to replace an existing currency or alter the exchange rate or exchange characteristics by devaluation or revaluation of a currency. Thus, a special risk in purchasing non-U.S. dollar notes is that their yields or payouts could be significantly and unpredictably affected by governmental actions. Even in the absence of governmental action directly affecting currency exchange rates, political or economic developments in the country issuing the specified currency for a non-U.S. dollar note or elsewhere could lead to significant and sudden changes in the exchange rate between the U.S. dollar and the specified currency. These changes could affect the value of the non-U.S. dollar note as participants in the global currency markets move to buy or sell the specified currency or U.S. dollars in reaction to these developments.

Governments have imposed from time to time and may in the future impose exchange controls or other conditions, including taxes, with respect to the exchange or transfer of a specified currency that could affect exchange rates as well as the availability of a specified currency for a note at its maturity or on any other payment date. In addition, the ability of a holder to move currency freely out of the country in which payment in the currency is received or to convert the currency at a freely determined market rate could be limited by governmental actions.

Non-U.S. Dollar Notes May Permit Us to Make Payments in U.S. Dollars or Delay Payment If We Are Unable to Obtain the Specified Currency

Non-U.S. dollar notes may provide that, if the specified currency is subject to convertibility, transferability, market disruption or other conditions affecting its availability at or about the time when a payment on the notes comes due because of circumstances beyond our control, we will be entitled to make the payment in U.S. dollars or delay making the payment. These circumstances could include the imposition of exchange controls or our inability to obtain the specified currency because of a disruption in the currency markets. If we make payment in U.S. dollars, the value of the payment in U.S. dollars an investor would receive on the payment date may be less than the value of the payment the investor would have received in the specified currency if it had been available, or may be zero. In addition, a government may impose extraordinary taxes on transfers of a currency. If that happens, we may be required and will be entitled to deduct or withhold these taxes from any payment on notes payable in that currency.

In a Lawsuit for Payment on a Non-U.S. Dollar Note, an Investor May Bear Currency Exchange Risk

The notes will be governed by New York law. Under Section 27 of the New York Judiciary Law, a state court in the State of New York rendering a judgment on a non-U.S. dollar note would be required to render the judgment in the specified currency. However, the judgment would be converted into U.S. dollars at the exchange

S-10

rate prevailing on the date of entry of the judgment. Consequently, in a lawsuit for payment on a non-U.S. dollar note, investors would bear currency exchange risk until judgment is entered, which may take a significant period of time.

In courts outside of New York, investors may not be able to obtain judgment in a specified currency other than U.S. dollars. For example, a judgment for money in an action based on a non-U.S. dollar note in many other U.S. federal or state courts ordinarily would be enforced in the United States only in U.S. dollars. The date used to determine the rate of conversion of the currency in which any particular note is denominated into U.S. dollars will depend upon various factors, including which court renders the judgment.

Historical Information About Exchange Rates May Not Be Indicative of Future Performance

If we issue a non-U.S. dollar note, we may include in the relevant pricing supplement a currency supplement that provides information about historical exchange rates for the relevant non-U.S. dollar currency or currencies. Any historical information about exchange rates that we may provide will be furnished as a matter of information only, and you should not regard such information as indicative of the further performance of currency exchange rates. That rate will likely differ from the exchange rate used under the terms that apply to a particular note.

Determinations Made by the Exchange Rate Agent

All determinations made by the exchange rate agent will be made in its sole discretion (except to the extent expressly provided in this prospectus supplement or the relevant pricing supplement that any determination is subject to approval by the Bank). In the absence of manifest error, its determinations will be conclusive for all purposes and will bind all holders and us. The exchange rate agent will not have any liability for its determinations.

Non-U.S. Investors May Be Subject to Certain Additional Risks

If we issue a U.S. dollar note and you are a non-U.S. investor who purchased such notes with a currency other than U.S. dollars, changes in rates of exchange may have an adverse effect on the value, price or income of your investment.

The accompanying prospectus contains a general description of certain U.S. and Canadian tax consequences relating to the notes. If you are a non-U.S. investor, you should consult your tax advisors as to the consequences, under the tax laws of the country where you are resident for tax purposes, of acquiring, holding and disposing of notes and receiving payments of principal or other amounts under the notes.

Risks Relating to Bail-Inable Notes

The Notes Will Be Subject to Risks, Including Non-Payment in Full or, in the Case of Bail-Inable Notes, Conversion in Whole or in Part – by Means of a Transaction or Series of Transactions and in One or More Steps – Into Common Shares of the Bank or Any of Its Affiliates, Under Canadian Bank Resolution Powers

Under Canadian bank resolution powers, the CDIC may, in circumstances where the Bank has ceased, or is about to cease, to be viable or in certain other circumstances, assume temporary control or ownership of the Bank and may be granted broad powers by one or more orders of the Governor in Council (Canada), each of which we refer to as an “Order,” including the power to sell or dispose of all or a part of the assets of the Bank, and the power to carry out or cause the Bank to carry out a transaction or a series of transactions the purpose of which is to restructure the business of the Bank. As part of the Canadian bank resolution powers, certain provisions of and regulations under the Bank Act, the CDIC Act and certain other Canadian federal statutes pertaining to banks provide for a bank recapitalization regime, which we refer to collectively as the “bail-in regime,” for banks designated by the Superintendent of Financial Institutions (Canada) (the “Superintendent”) as “domestic systemically important banks”, or “D-SIBs”, which include the Bank.  See “Description of Senior Debt Securities ― Canadian Bank Resolution Powers” in the accompanying prospectus for a description of the Canadian bank resolution powers, including the bail-in regime.

If the CDIC were to take action under the Canadian bank resolution powers with respect to the Bank, this could result in holders or beneficial owners of the notes being exposed to losses and, in the case of bail-inable notes, conversion of the notes in whole or in part – by means of a transaction or series of transactions and in one or more steps – into common shares of the Bank or any of its affiliates, which we refer to as a “bail-in conversion.” Subject to certain exceptions discussed in the accompanying prospectus under “Description of Senior Debt Securities ― Canadian Bank Resolution Powers,” including for certain structured notes, senior debt issued on or after September

S-11

23, 2018, with an initial or amended term to maturity (including explicit or embedded options) greater than 400 days, that is unsecured or partially secured and that has been assigned a CUSIP or ISIN or similar identification number, is subject to bail-in conversion, unless they are non-viability contingent capital. We refer to notes that are subject to bail-in conversion as “bail-inable notes.”

Upon a bail-in conversion, if your bail-inable notes or any portion thereof are converted into common shares of the Bank or any of its affiliates, you will be obligated to accept those common shares, even if you do not at the time consider the common shares to be an appropriate investment for you, and despite any change in the Bank or any of its affiliates, or the fact that the common shares may be issued by an affiliate of the Bank, or any disruption to or lack of a market for the common shares or disruption to capital markets generally.

As a result, you should consider the risk that you may lose all of your investment, including the principal amount plus any accrued interest, if the CDIC were to take action under the Canadian bank resolution powers, including the bail-in regime, and that any remaining outstanding notes, or common shares of the Bank or any of its affiliates into which bail-inable notes are converted, may be of little value at the time of a bail-in conversion and thereafter.

The Indenture Will Provide Only Limited Acceleration and Enforcement Rights for the Notes and Includes Other Provisions Intended to Qualify Bail-Inable Notes as TLAC

In connection with the bail-in regime, the Superintendent guideline on Total Loss Absorbing Capacity (“TLAC”) (the “TLAC Guideline”) applies to and establishes standards for D-SIBs, including the Bank. Under the TLAC Guideline, the Bank is required to maintain an amount of unsecured external long-term debt that meets the prescribed criteria or regulatory capital instruments to support recapitalization in the event of a failure. Bail-inable notes and regulatory capital instruments that meet certain prescribed criteria, which are discussed in the accompanying prospectus under “Description of Senior Debt Securities ― Canadian Bank Resolution Powers,” will constitute TLAC of the Bank.

In order to comply with the TLAC Guideline, our indenture under which the notes may be issued provides that, for any notes of a series issued on or after September 23, 2018 (including notes that are not subject to bail-in conversion), acceleration will only be permitted (i) if we default in the payment of the principal of, or interest on, any note of that series and, in each case, the default continues for a period of 30 business days, and the Bank clearly discloses certain prescribed matters to investors, or (ii) certain bankruptcy, insolvency, wind-up or liquidation events occur.

Holders and beneficial owners of bail-inable notes may only exercise, or direct the exercise of, the rights described in the accompanying prospectus under “Description of Senior Debt Securities — Events of Default — Remedies If an Event of Default Occurs” where an Order has not been made under Canadian bank resolution powers pursuant to subsection 39.13(1) of the CDIC Act in respect of the Bank. Notwithstanding the exercise of those rights, bail-inable notes will continue to be subject to bail-in conversion until repaid in full. For greater certainty, no person may terminate or amend any agreement with the Bank that is in relation to any of the Bank’s bail-inable notes, claim an accelerated payment or forfeiture of the term under such an agreement or demand payment of any amount under such an agreement, by reason only of a monetary default by the Bank in the performance of bail-inable notes, when that default occurs after a bail-in conversion order is made under paragraph 39.13(1)(d) of the CDIC Act but before the bail-in conversion.

The indenture also provides that holders or beneficial owners of bail-inable notes will not be entitled to exercise, or direct the exercise of, any set-off or netting rights with respect to bail-inable notes. In addition, where an amendment, modification or other variance that can be made to the indenture or the bail-inable notes as described in the accompanying prospectus under “Description of Senior Debt Securities — Modification and Waiver of the Senior Debt Securities” would affect the recognition of those bail-inable notes by the Superintendent as TLAC, that amendment, modification or variance will require the prior approval of the Superintendent.

The Circumstances Surrounding a Bail-In Conversion Are Unpredictable and Can Be Expected to Have an Adverse Effect on the Market Price of Bail-Inable Notes

The decision as to whether the Bank has ceased, or is about to cease, to be viable is a subjective determination by the Superintendent that is outside the control of the Bank. Upon a bail-in conversion, the interests of depositors and holders of liabilities and securities of the Bank that are not converted will effectively all rank in priority to the portion of bail-inable notes that are converted. In addition, except as provided for under the

S-12

compensation process, the rights of holders in respect of the bail-inable notes that have been converted will rank on parity with other holders of common shares of the Bank (or, as applicable, common shares of the affiliate whose common shares are issued on the bail-in conversion).

There is no limitation on the type of Order that may be made where it has been determined that the Bank has ceased, or is about to cease, to be viable. As a result, you may be exposed to losses through the use of Canadian bank resolution powers other than bail-in conversion or in liquidation. See “The Notes Will Be Subject to Risks, Including Non-Payment in Full or, in the Case of Bail-Inable Notes, Conversion in Whole or in Part – by Means of a Transaction or Series of Transactions and in One or More Steps – Into Common Shares of the Bank or Any of Its Affiliates, Under Canadian Bank Resolution Powers” above.

Because of the uncertainty regarding when and whether an Order will be made and the type of Order that may be made, it will be difficult to predict when, if at all, bail-inable notes could be converted into common shares of the Bank or any of its affiliates, and there is not likely to be any advance notice of an Order. As a result of this uncertainty, trading behavior in respect of the bail-inable notes may not follow trading behavior associated with convertible or exchangeable securities or, in circumstances where the Bank is trending towards ceasing to be viable, other senior debt. Any indication, whether real or perceived, that the Bank is trending towards ceasing to be viable can be expected to have an adverse effect on the market price of the bail-inable notes, whether or not the Bank has ceased, or is about to cease, to be viable. Therefore, in those circumstances, you may not be able to sell your bail-inable notes easily or at prices comparable to those of senior debt securities not subject to bail-in conversion.

The Number of Common Shares to Be Issued in Connection With, and the Number of Common Shares That Will Be Outstanding Following, a Bail-In Conversion Are Unknown. It Is Also Unknown Whether the Shares to Be Issued Will Be Those of the Bank or One of Its Affiliates

Under the bail-in regime there is no fixed and pre-determined contractual conversion ratio for the conversion of the bail-inable notes, or other shares or liabilities of the Bank that are subject to a bail-in conversion, into common shares of the Bank or any of its affiliates, nor are there specific requirements regarding whether liabilities subject to a bail-in conversion are converted into common shares of the Bank or any of its affiliates. The CDIC determines the timing of the bail-in conversion, the portion of bail-inable shares and liabilities to be converted and the terms and conditions of the conversion, subject to parameters set out in the bail-in regime, which are discussed under “Description of Senior Debt Securities ― Canadian Bank Resolution Powers” in the accompanying prospectus.

As a result, it is not possible to anticipate the potential number of common shares of the Bank or its affiliates that would be issued in respect of any bail-inable note converted in a bail-in conversion, the aggregate number of such common shares that will be outstanding following the bail-in conversion, the effect of dilution on the common shares received from other issuances under or in connection with an Order or related actions in respect of the Bank or its affiliates or the value of any common shares you may receive for your converted bail-inable notes, which could be significantly less than the principal amount of those bail-inable notes. It is also not possible to anticipate whether shares of the Bank or shares of its affiliates would be issued in a bail-in conversion. There may be an illiquid market, or no market at all, in the common shares issued upon a bail-in conversion and you may not be able to sell those common shares at a price equal to the value of your converted bail-inable notes and as a result may suffer significant losses that may not be offset by compensation, if any, received as part of the compensation process. Fluctuations in exchange rates may exacerbate those losses.

By Acquiring Bail-Inable Notes, You Are Deemed to Agree to Be Bound by a Bail-In Conversion and So Will Have No Further Rights in Respect of Your Bail-Inable Notes to the Extent Those Bail-Inable Notes Are Converted in a Bail-In Conversion Other Than Those Provided Under the Bail-In Regime. Any Potential Compensation to Be Provided Through the Compensation Process Under the CDIC Act Is Unknown

The CDIC Act provides for a compensation process for holders of bail-inable notes who immediately prior to the making of an Order, directly or through an intermediary, own bail-inable notes that are converted in a bail-in conversion. Given the considerations involved in determining the amount of compensation, if any, that a holder that held bail-inable notes may be entitled to following an Order, it is not possible to anticipate what, if any, compensation would be payable in such circumstances. By acquiring an interest in any bail-inable note, you are deemed to agree to be bound by a bail-in conversion and so will have no further rights in respect of your bail-inable notes to the extent those bail-inable notes are converted in a bail-in conversion, other than those provided under the

S-13

bail-in regime. See “Description of Senior Debt Securities ― Canadian Bank Resolution Powers” in the accompanying prospectus for a description of the compensation process under the CDIC Act.

Following a Bail-In Conversion, Holders or Beneficial Owners That Held Bail-Inable Notes That Have Been Converted Will No Longer Have Rights Against the Bank as Creditors

Upon a bail-in conversion, the rights, terms and conditions of the portion of bail-inable notes that are converted, including with respect to priority and rights on liquidation, will no longer apply as the portion of converted bail-inable notes will have been converted on a full and permanent basis into common shares of the Bank or any of its affiliates ranking on parity with all other outstanding common shares of that entity. If a bail-in conversion occurs, then the interest of the depositors, other creditors and holders of liabilities of the Bank not bailed in as a result of the bail-in conversion will all rank in priority to those common shares.

Given the nature of the bail-in conversion, holders or beneficial owners of bail-inable notes that are converted will become holders or beneficial owners of common shares at a time when the Bank’s and potentially its affiliates’ financial condition has deteriorated. They may also become holders or beneficial owners of common shares at a time when the relevant entity may have received or may receive a capital injection or equivalent support with terms that may rank in priority to the common shares issued in a bail-in conversion with respect to payment of dividends, rights on liquidation or other terms although there is no certainty that any such capital injection or support will be forthcoming.

We May Redeem Bail-Inable Notes After the Occurrence of a TLAC Disqualification Event

If a TLAC Disqualification Event (as defined below) is specified in the relevant pricing supplement, we may, at our option, with the prior approval of the Superintendent, redeem all but not less than all of the particular bail-inable notes prior to their stated maturity date after the occurrence of the TLAC Disqualification Event, at the time or times and at the redemption price or prices specified in that pricing supplement, together with unpaid interest accrued thereon to, but excluding, the date fixed for redemption. If we redeem bail-inable notes, you may not be able to reinvest the redemption proceeds in securities offering a comparable anticipated rate of return. Additionally, although the terms of the bail-inable notes are anticipated to be established to satisfy the TLAC criteria within the meaning of the TLAC Guideline to which the Bank is subject, it is possible that any bail-inable notes may not satisfy the criteria in future rulemakings or interpretations.

S-14

USE OF PROCEEDS

Except as otherwise set forth in a pricing supplement, the net proceeds from the sale of any notes will be added to our general funds and will be used for general corporate purposes. We and/or our affiliates may use a portion of the proceeds in transactions intended to hedge our obligations under the notes.

S-15

DESCRIPTION OF THE NOTES WE MAY OFFER

You should carefully read the description of the terms and provisions of our debt securities and our indenture under “Description of Senior Debt Securities” in the accompanying prospectus. That section, together with this prospectus supplement and the relevant pricing supplement, summarizes the material terms of our indenture and your notes. They do not, however, describe every aspect of our indenture and your notes. For example, in this section entitled “Description of the Notes We May Offer”, the accompanying prospectus and the relevant pricing supplement, we use terms that have been given special meanings in our indenture, but we describe the meanings of only the more important of those terms. The specific terms of any series of notes will be described in the relevant pricing supplement. As you read this section, please remember that the specific terms of your notes as described in the relevant pricing supplement will supplement and, if applicable, may modify or replace the general terms described in this section. If the relevant pricing supplement is inconsistent with this prospectus supplement or the accompanying prospectus, the relevant pricing supplement will control with regard to your notes. Thus, the statements we make in this section may not apply to your notes.

General

The notes will be issued under the indenture, dated as of September 15, 2012, between the Bank and Deutsche Bank Trust Company Americas, as trustee, as supplemented by the first supplemental indenture, dated as of November 6, 2018, and the second supplemental indenture, dated as of December 16, 2019, and as further amended from time to time, which we may refer to as the “indenture”. The notes constitute a single series of debt securities of the Bank issued under the indenture. The term “debt securities”, as used in this prospectus supplement, refers to all debt securities, including the notes, issued and issuable from time to time under the indenture. The indenture is subject to, and governed by, the U.S. Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). The indenture is more fully described below in this section. Whenever we refer to specific provisions or defined terms in the indenture, those provisions or defined terms are incorporated in this prospectus supplement by reference. Capitalized terms which are not otherwise defined shall have the meanings given to them in the indenture.

The notes will be limited to an aggregate initial offering price of US$20,000,000,000 or, at our option if so specified in the relevant pricing supplement, the equivalent of this amount in any other currency or currency unit, and will be our direct, unsecured obligations. This aggregate initial offering price is subject to reduction as a result of the sale by us of other debt securities pursuant to another prospectus supplement to the accompanying prospectus. The notes will not constitute deposits insured under the CDIC Act or by the United States Federal Deposit Insurance Corporation or any other Canadian or United States governmental agency or instrumentality.

We will offer the notes on a continuous basis through one or more agents. The indenture does not limit the aggregate principal amount of senior notes that we may issue. We may, from time to time, without the consent of the holders of the notes, provide for the issuance of notes or other debt securities under the indenture in addition to the US$20,000,000,000 aggregate initial offering price of notes noted on the cover of this prospectus supplement. Each note issued under this prospectus supplement will have a stated maturity that will be specified in the relevant pricing supplement and may be subject to redemption or repayment before its stated maturity. Notes may be issued at significant discounts from their principal amount due on the stated maturity (or on any prior date on which the principal or an installment of principal of a note becomes due and payable, whether by the declaration of acceleration, call for redemption at our option, repayment at the option of the holder or otherwise), and some notes may not bear interest. We may from time to time, without the consent of the existing holders of the relevant notes, create and issue further notes having the same terms and conditions as such notes in some or all respects.

Unless we specify otherwise in the relevant pricing supplement, currency amounts in this prospectus supplement are expressed in U.S. dollars. Unless we specify otherwise in any note and pricing supplement, the notes will be denominated in U.S. dollars and payments of principal, premium, if any, and any interest on the notes will be made in U.S. dollars. If any note is to be denominated other than exclusively in U.S. dollars, or if the principal of, premium, if any, or any interest on the note is to be paid in one or more currencies (or currency units or in amounts determined by reference to an index or indices) other than that in which that note is denominated, additional information (including authorized denominations and related exchange rate and exchange agent information) will be provided in the relevant pricing supplement. Unless we specify otherwise in any pricing supplement, notes denominated in U.S. dollars will be issued in minimum denominations of $1,000 and integral multiples of $1,000 in excess thereof (except that non-U.S. investors may be subject to higher minimums).

S-16

Interest rates that we offer on the notes may differ depending upon, among other factors, the aggregate principal amount of notes purchased in any single transaction. Notes with different variable terms other than interest rates may also be offered concurrently to different investors. We may change interest rates or formulas and other terms of notes from time to time, but no change of terms will affect any note we have previously issued or as to which we have accepted an offer to purchase.

Each note will be issued as a book-entry note in fully registered form without coupons. Each note issued in book-entry form may be represented by a global note that we deposit with and register in the name of a financial institution or its nominee, that we select. The financial institution that we select for this purpose is called the “depositary”. Unless we specify otherwise in the relevant pricing supplement, DTC will be the depositary for all notes in global form. Except as discussed in the accompanying prospectus under “Description of Senior Debt Securities—Legal Ownership and Book-Entry Issuance,” owners of beneficial interests in book-entry notes will not be entitled to physical delivery of notes in certificated form. We will make payments of principal of, and premium, if any and interest, if any, on the notes through the trustee or applicable paying agent to the depositary for the notes.

Legal Ownership

Street Name and Other Indirect Holders

Investors who hold their notes in accounts at banks, brokers or other financial institutions will generally not be recognized by us as legal holders of notes. This is called holding in street name. Instead, we would recognize only the bank or broker, or the financial institution the bank or broker uses to hold its notes. These intermediary banks, brokers and other financial institutions pass along principal, interest and other payments on the notes, either because they agree to do so in their customer agreements or because they are legally required to do so. If you hold your notes in street name, you should check with your own institution to find out:

●how it handles note payments and notices;

●whether it imposes fees or charges;

●how it would handle voting if it were ever required;

●whether and how you can instruct it to send you notes registered in your own name so you can be a direct holder as described below; and

●how it would pursue rights under the notes if there were a default or other event triggering the need for holders to act to protect their interests.

Direct Holders

Our obligations, as well as the obligations of the trustee and those of any third parties employed by us or the trustee, under the notes are only to persons who are registered as holders of notes. As noted above, we do not have obligations to you if you hold your notes in street name or other indirect means, either because you choose to hold your notes in that manner or because the notes are issued in the form of global notes, as described below. For example, once we make a payment to the registered holder, we have no further responsibility for the payment, even if that holder is legally required to pass the payment along to you as a street name customer but does not do so.

Global Notes

A global note is a special type of indirectly held security, as described under “—Legal Ownership—Street Name and Other Indirect Holders” above. If we choose to issue notes in the form of a global note, the ultimate beneficial owners of such global note can only be indirect holders. We require that the global note be registered in the name of a financial institution we select.

We also require that the notes included in the global note not be transferred to the name of any other direct holder except in the special circumstances described in the accompanying prospectus under “Description of Senior Debt Securities—Legal Ownership and Book-Entry Issuance.” Any person wishing to own a global note must do so indirectly by virtue of an account with a broker, bank or other financial institution, known as a “participant”, that in turn has an account with the depositary. The relevant pricing supplement will indicate whether your series of notes will be issued only in the form of global notes.

Further details of legal ownership are discussed in the accompanying prospectus under “Description of Senior Debt Securities—Legal Ownership and Book-Entry Issuance.”

S-17

In the remainder of this description, “you” or “holder” means direct holders and not street name or other indirect holders of notes. Indirect holders should read the subsection entitled “—Legal Ownership—Street Name and Other Indirect Holders” above.

Types of Notes

We may issue the following types of notes:

●Fixed Rate Notes. A note of this type will bear interest at a fixed rate described in the relevant pricing supplement. This type includes zero-coupon notes, which bear no interest and are instead issued at a price lower than the principal amount.

●Floating Rate Notes. A note of this type will bear interest at rates that are determined by reference to an interest rate formula. In some cases, the rates may also be adjusted by adding or subtracting a spread or multiplying by a spread multiplier and may be subject to a minimum rate or a maximum rate. The various interest rate formulas and these other features are described under “—Interest Rates—Floating Rate Notes” below. If your note is a floating rate note, the formula and any adjustments that apply to the interest rate will be specified in the relevant pricing supplement.

●Fixed-to-Floating Rate Notes. A note of this type will bear interest at both a fixed rate for a certain period of time and at a floating rate for another certain period of time determined by reference to an interest rate formula, each as specified in the relevant pricing supplement. We refer to these notes as “fixed-to-floating rate notes.” The rate for the floating-rate period(s) for a fixed-to-floating rate note will be set, calculated and paid in the same manner as for floating rate notes, as described in this prospectus supplement and as specified in the relevant pricing supplement. Any references to or discussion of floating-rate notes in this prospectus supplement also applies to the floating-rate period(s) of fixed-to-floating rate notes.

●Floating-to-Fixed Rate Notes. A note of this type will bear interest at both a floating rate for a certain period of time and at a fixed rate for another certain period of time determined by reference to an interest rate formula, each as specified in the relevant pricing supplement. We refer to these notes as “floating-to-fixed rate notes.” The rate for the floating-rate period(s) for a floating-to-fixed rate note will be set, calculated and paid in the same manner as for floating-rate notes, as described in this prospectus supplement and as specified in the relevant pricing supplement. Any references to or discussion of floating-rate notes in this prospectus supplement also applies to the floating-rate period(s) of floating-to-fixed rate notes.

●Indexed Notes. A note of this type provides that the amount payable at its maturity, and/or the amount of interest payable on an interest payment date, will be determined by reference to a “market measure” consisting of:

—          one or more securities;

—          one or more currencies;

—          one or more commodities;

—          one or more indices;

—          one or more exchange traded funds;

—any other financial, economic or other measures or instruments, including the occurrence or non-occurrence of any event or circumstance; and/or

—          one or more baskets of any of these items.

If you are a holder of an indexed note, you may receive an amount at maturity that is greater than, equal to or less than the principal amount of your note depending upon the value of the applicable index at maturity. That value may fluctuate over time. If you purchase an indexed note, the relevant pricing supplement will include information about the relevant index and how amounts that are to become payable will be determined by reference to that index. In addition, the relevant pricing supplement will specify whether your note will be payable in cash or exchangeable for securities of an issuer other than the Bank or other property. Contingent payments on indexed notes are not considered interest for purposes of New York usury law. In some cases, interest on indexed notes may

S-18

be subject to Canadian non-resident withholding tax. See “Material Income Tax Consequences – Canadian Taxation” in the accompanying prospectus. The relevant pricing supplement will describe the material U.S. federal income tax consequences of the purchase, ownership or disposition of an indexed note, and may supplement the description of Canadian federal income tax considerations with respect thereto in the accompanying prospectus. Before you purchase any indexed note, you should read carefully the section entitled “Risk Factors—Risks Relating to Indexed Notes” above.

Original Issue Discount Notes

A note may be an original issue discount note. A note of this type is issued at a price lower than its principal amount and provides that, upon redemption or acceleration of its maturity, an amount less than its principal amount will be payable. An original issue discount note may be a zero-coupon note. A note issued at a discount to its principal may, for U.S. federal income tax purposes, be considered an original issue discount note, regardless of the amount payable upon redemption or acceleration of maturity. The relevant pricing supplement relating to any original issue discount notes will describe any special considerations and any material U.S. tax considerations relevant to the acquisition of such notes.

Information in the Pricing Supplement

The relevant pricing supplement will describe one or more of the following terms of your note:

●the CUSIP number;

●the stated maturity;

●the specified currency or currencies for principal and interest, if not U.S. dollars;

●if other than $1,000 and integral multiples thereof, the denominations in which the notes may be issued;

●the price at which we originally issue your note and the original issue date;

●whether or not your note is a bail-inable note;

●whether your note is a fixed rate note, a floating rate note, a fixed-to-floating rate note, a floating-to-fixed rate note, or an indexed note;

●if your note is a fixed rate note, the per annum rate at which your note will bear interest, if any, and the interest payment dates;

●if your note is a floating rate note, the interest rate basis, which may be one of the interest rate bases described under “—Interest Rates—Floating Rate Notes” below; any applicable index currency or maturity, spread or spread multiplier or initial, maximum or minimum rate; and the interest reset, determination, calculation and payment dates, all of which we describe under “—Interest Rates—Floating Rate Notes” below;

●if your note is an indexed note, the principal amount, if any, we will pay you at maturity, the amount of interest, if any, we will pay you on an interest payment date or the formula we will use to calculate these amounts, if any, and whether your note will be exchangeable for cash, securities of an issuer other than the Bank or other property;

●if your note is an original issue discount note, the yield to maturity;

●if applicable, the circumstances under which your note may be redeemed at our option before the stated maturity, including any redemption commencement date, redemption price(s) and redemption period(s);

●if applicable, the circumstances under which you may demand repayment of your note before the stated maturity, including any repayment commencement date, repayment price(s) and repayment period(s);

●any material U.S. federal income tax consequences of the purchase, ownership or disposition of a particular issuance of notes;

S-19

●the use of proceeds, if materially different than those discussed in this prospectus supplement; and

●any other terms of your note, which could be different from those described in this prospectus supplement.

Market-Making Transactions

If you purchase your note in a market-making transaction, you will receive information about the price you pay and your trade and settlement dates in a separate confirmation of sale. A market-making transaction is one in which an agent or other person resells a note that it has previously acquired from another holder. A market-making transaction in a particular note occurs after the original sale of the note.

Redemption at the Option of the Bank; No Sinking Fund

If an initial redemption date is specified in the relevant pricing supplement, we may redeem the particular notes prior to their stated maturity date at our option on any date on or after that initial redemption date in whole or from time to time in part in increments of any authorized denomination specified in the relevant pricing supplement (provided that any remaining principal amount thereof shall be at least the minimum authorized denomination applicable thereto), at the redemption price or prices specified in that pricing supplement, together with unpaid interest accrued thereon to the date of redemption. Unless otherwise specified in the relevant pricing supplement, we must give written notice to registered holders of the particular notes to be redeemed at our option not less than 20 business days prior to the date of redemption.

If the relevant pricing supplement specifies that the notes are bail-inable notes, in the event that a redemption (for any reason) of such notes would lead to a breach of the Bank’s TLAC requirements, such redemption would be subject to the prior approval of the Superintendent. See “Description of Senior Debt Securities – Canadian Bank Resolution Powers – TLAC Guideline” in the accompanying prospectus for additional information.

The notes will not be subject to, or entitled to the benefit of, any sinking fund.

Repayment at the Option of the Holder

If one or more optional repayment dates are specified in the relevant pricing supplement, registered holders of the particular notes may require us to repay those notes prior to their stated maturity date on any optional repayment date in whole or from time to time in part in increments of any authorized denomination specified in the relevant pricing supplement (provided that any remaining principal amount thereof shall be at least the minimum authorized denomination applicable thereto), at the repayment price or prices specified in that pricing supplement, together with unpaid interest accrued thereon to the date of repayment. A registered holder’s exercise of the repayment option will be irrevocable.

For any note to be repaid, the trustee must receive, at its corporate trust office in the Borough of Manhattan, The City of New York, not less than 20 business days prior to the date of repayment, the particular notes to be repaid and, in the case of a book-entry note, repayment instructions from the applicable beneficial owner to the depositary and forwarded by the depositary. Only the depositary may exercise the repayment option in respect of global notes representing book-entry notes. Accordingly, beneficial owners of global notes that desire to have all or any portion of the book-entry notes represented thereby repaid must instruct the participant through which they own their interest to direct the depositary to exercise the repayment option on their behalf by forwarding the repayment instructions to the trustee as aforesaid. In order to ensure that these instructions are received by the trustee on a particular day, the applicable beneficial owner must so instruct the participant through which it owns its interest before that participant’s deadline for accepting instructions for that day. Different firms may have different deadlines for accepting instructions from their customers. Accordingly, beneficial owners should consult their participants for the respective deadlines. In addition, at the time repayment instructions are given, each beneficial owner shall cause the participant through which it owns its interest to transfer the beneficial owner’s interest in the global note representing the related book-entry notes, on the depositary’s records, to the applicable trustee.

We will comply with the applicable requirements of the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules promulgated thereunder, and any other securities laws or regulations in connection with any repayment of notes at the option of the registered holders thereof.

We may at any time purchase notes at any price or prices in the open market or otherwise. Notes so purchased by us may, at our discretion, be held, resold or surrendered to the trustee for cancellation. Where our

S-20

repurchase of bail-inable notes would lead to a breach of the Bank’s TLAC requirements, such repurchase would be subject to the prior approval of the Superintendent.

Interest

Each interest-bearing note will bear interest from its date of issue at the rate per annum, in the case of a fixed rate note, or pursuant to the interest rate formula, in the case of a floating rate note, in each case as specified in the relevant pricing supplement, until the principal thereof is paid. We will make interest payments in an amount equal to the interest accrued from and including the immediately preceding interest payment date in respect of which interest has been paid or from and including the date of issue, if no interest has been paid, to but excluding the applicable interest payment date, the redemption date or the maturity date, as the case may be (each, an “interest period”).

Interest will be payable in arrears on each interest payment date, on any redemption date and on the maturity date. Interest will be payable to the persons in whose names the notes are registered at the close of business on the business day immediately preceding the related interest payment date (the “regular record date”), and the final interest payable at maturity or upon an early redemption, as applicable, will be payable to the persons in whose names the notes are registered on the maturity date or the early redemption date, as applicable. For the purpose of determining the holder at the close of business on a regular record date when business is not being conducted, the close of business will mean 5:00 P.M., New York City time, on that day. “Business day” is defined below under “—Interest Rates—Special Rate Calculation Terms.”

Interest Rates

This subsection describes the different kinds of interest rates that may apply to your note, if it bears interest.

Fixed Rate Notes

The relevant pricing supplement will specify the interest payment dates for a fixed rate note as well as the maturity date. Interest on fixed rate notes will be computed on the basis of a 360-day year consisting of twelve 30-day months or such other day count convention set forth in the relevant pricing supplement. For the purposes of disclosure under the Interest Act (Canada), and without affecting the interest payable on any fixed rate note, whenever the interest rate on any fixed rate note is to be calculated on the basis of a period of less than a calendar year, the yearly interest rate equivalent for such interest rate will be the interest rate multiplied by the actual number of calendar days in the relevant calendar year and divided by the number of calendar days used in calculating the specified interest rate.

If any interest payment date, redemption date, repayment date or maturity date of a fixed rate note falls on a day that is not a business day, we will make the required payment of any principal, premium, and/or interest on the next succeeding business day unless otherwise specified in the relevant pricing supplement, and no additional interest will accrue in respect of the payment made on that next succeeding business day.

Floating Rate Notes

In this subsection, we use several specialized terms relating to the manner in which floating interest rates are calculated. We define these terms under “—Special Rate Calculation Terms” below.

The following will apply to floating rate notes:

Interest Rate Basis. We currently expect to issue floating rate notes that bear interest at rates based on one or more of the following interest rate bases:

●commercial paper rate;

●U.S. prime rate;

●EURIBOR;

●SOFR (based on compounding or a weighted average);

●USD SOFR ICE Swap Rate;

●treasury rate;

S-21

●CMT rate;

●CPI rate; and/or

●federal funds rate.

We describe each of the interest rate bases in further detail below in this subsection. If you purchase a floating rate note, the relevant pricing supplement will specify the interest rate basis that applies to your note. If your floating rate note has an interest rate basis other than those listed above, your pricing supplement will describe the applicable interest rate basis.

Calculation of Interest. Calculations relating to floating rate notes will be made by the calculation agent, an institution that we appoint as our agent for this purpose. That institution may include us or any affiliate of ours, such as CIBCWM. The pricing supplement for a particular floating rate note will name the institution that we have appointed to act as the calculation agent for that note as of its original issue date. We may appoint a different institution to serve as calculation agent from time to time after the original issue date of the note without your consent and without notifying you of the change.

For each floating rate note, the calculation agent will determine, on the corresponding interest calculation date or on the interest determination date, as described below, the interest rate that takes effect on each interest reset date or in the case of a note for which the interest basis is SOFR (exclusive of the USD SOFR ICE Swap Rate) or another backward looking rate, the interest rate for the applicable interest period. In addition, the calculation agent will calculate the amount of interest that has accrued during each interest period—that is, the period from and including the original issue date, or the last date to which interest has been paid or made available for payment, to but excluding the payment date. If the interest rate basis is not SOFR (exclusive of the USD SOFR ICE Swap Rate) or another backward looking rate, for each interest period, the calculation agent will calculate the amount of accrued interest by multiplying the principal amount of the floating rate note by an accrued interest factor for the interest period. This factor will equal the sum of the interest factors calculated for each day during the interest period. The interest factor for each day will be expressed as a decimal and will be calculated by dividing the interest rate, also expressed as a decimal, applicable to that day by 360 or by the actual number of calendar days in the year, as specified in the relevant pricing supplement. For the purposes of disclosure under the Interest Act (Canada), and without affecting the interest payable on any floating rate note, whenever the interest rate on any floating rate note is to be calculated on the basis of a period of less than a calendar year, the yearly interest rate equivalent for that interest rate will be the interest rate multiplied by the actual number of calendar days in the relevant calendar year and divided by the number of calendar days used in calculating the specified interest rate. In no event will the interest on any floating rate note be less than zero.

If the interest rate basis is not SOFR (exclusive of the USD SOFR ICE Swap Rate) or another backward looking rate, upon the request of the holder of any floating rate note, the calculation agent will provide for that note the interest rate then in effect — and, if determined, the interest rate that will become effective on the next interest reset date. If the interest basis is SOFR (exclusive of the USD SOFR ICE Swap Rate) or another backward looking rate, upon the request of the holder of any floating rate note, the calculation agent will provide the interest rate most recently calculated for that note, which may not be the interest rate applicable to the current interest period. The calculation agent’s determination of any interest rate, and its calculation of the amount of interest for any interest period, will be final and binding in the absence of manifest error.

All percentages resulting from any calculation relating to a note will be rounded upward or downward, as appropriate, to the next higher or lower one hundred-thousandth of a percentage point, e.g., 9.876541% (or .09876541) being rounded down to 9.87654% (or .0987654) and 9.876545% (or .09876545) being rounded up to 9.87655% (or .0987655). All amounts used in or resulting from any calculation relating to a floating rate note will be rounded upward or downward, as appropriate, to the nearest cent, in the case of U.S. dollars, or to the nearest corresponding hundredth of a unit, in the case of a currency other than U.S. dollars, with one-half cent or one-half of a corresponding hundredth of a unit or more being rounded upward.

In determining the interest rate basis that applies to a floating rate note during a particular interest period, the calculation agent may obtain rate quotes from various banks or dealers active in the relevant market, as discussed below. Those reference banks and dealers may include the calculation agent itself and its affiliates, as well as any agent participating in the distribution of the relevant floating rate notes and its affiliates, and they may include our affiliates.

S-22

Initial Interest Rate. For any floating rate note, the interest rate in effect from the original issue date to the first interest reset date will be the initial interest rate. We will specify the initial interest rate or the manner in which it is determined in the relevant pricing supplement.

Spread or Spread Multiplier. In some cases, the interest rate basis for a floating rate note may be adjusted:

●by adding or subtracting a specified number of basis points, called the spread, with one basis point being 0.01%; or

●by multiplying the interest rate basis by a specified percentage, called the spread multiplier.

If you purchase a floating rate note, the relevant pricing supplement will indicate whether a spread or spread multiplier will apply to your note and, if so, the amount of the spread or spread multiplier.

Maximum and Minimum Rates. The actual interest rate, after being adjusted by the spread or spread multiplier, may also be subject to either or both of the following limits:

●a maximum rate—i.e., a specified upper limit that the actual interest rate in effect at any time may not exceed; and/or

●a minimum rate—i.e., a specified lower limit that the actual interest rate in effect at any time may not fall below.

If you purchase a floating rate note, the relevant pricing supplement will indicate whether a maximum rate and/or minimum rate will apply to your note and, if so, what those rates are.

Whether or not a maximum rate applies, the interest rate on a floating rate note will in no event be higher than the maximum rate permitted by New York law, as it may be modified by U.S. law of general application, and the Criminal Code (Canada). Under current New York law, the maximum rate of interest, with some exceptions, for any loan in an amount less than $250,000 is 16% and for any loan in the amount of $250,000 or more but less than $2,500,000 is 25% per year on a simple interest basis. These limits do not apply to loans of $2,500,000 or more. The Criminal Code (Canada) limits the effective annual interest rate to 60%, although any amounts payable in excess of this limit would be paid out over time to ensure that such payments do not exceed 60% per year. See “Risk Factors—Structure Risks—The Notes May Be Subject to Risks Related to Canadian Usury Laws” above.

The rest of this subsection describes how the interest rate and the interest payment dates will be determined, and how interest will be calculated, on a floating rate note.

Interest Reset Dates. The rate of interest on a floating rate note, other than a SOFR note or a floating rate note based on another backward looking rate, will be reset, by the calculation agent described below, daily, weekly, monthly, quarterly, semi-annually or annually. The date on which the interest rate resets and the reset rate becomes effective is called the “interest reset date”. Except as otherwise specified in the relevant pricing supplement, the interest reset date will be as follows:

●for floating rate notes that reset daily, each business day;

●for floating rate notes that reset weekly and are not treasury rate notes, the Wednesday of each week;

●for treasury rate notes that reset weekly, the Tuesday of each week;

●for floating rate notes that reset monthly, the third Wednesday of each month;

●for floating rate notes that reset quarterly, the third Wednesday of each of the four months of each year as indicated in the relevant pricing supplement;

●for floating rate notes that reset semi-annually, the third Wednesday of each of the two months of each year as indicated in the relevant pricing supplement; and

●for floating rate notes that reset annually, the third Wednesday of the one month of each year as indicated in the relevant pricing supplement.

For a floating rate note other than a SOFR (exclusive of the USD SOFR ICE Swap Rate) note or a floating rate note based on another backward looking rate, the interest rate in effect on any particular day will be the interest

S-23

rate determined with respect to the latest interest reset date that occurs on or before that day. There are several exceptions, however, to the reset provisions described above. For example, for a SOFR (exclusive of the USD SOFR ICE Swap Rate) note, the interest rate in effect on any particular day will be the interest rate determined with respect to the interest period in which that day occurs.

If any interest reset date for a floating rate note would otherwise be a day that is not a business day, the interest reset date will be postponed to the next day that is a business day. For a EURIBOR note, however, if that business day is in the next succeeding calendar month, the interest reset date will be the immediately preceding business day.

Interest Determination Dates. The interest rate that takes effect on an interest reset date (or, in the case of a SOFR (exclusive of the USD SOFR ICE Swap Rate) note or a floating rate note based on another backward looking rate, the interest rate determined for the applicable interest period) will be determined by the calculation agent by reference to a particular date called an interest determination date. Except as otherwise indicated in the relevant pricing supplement:

●for commercial paper rate, U.S. prime rate and federal funds rate notes, the interest determination date relating to a particular interest reset date will be the business day preceding the interest reset date;

●for EURIBOR notes, the interest determination date relating to a particular interest reset date will be the second TARGET Settlement Day preceding the interest reset date;

●for SOFR (exclusive of the USD SOFR ICE Swap Rate) notes and floating rate notes based on other backward looking rates, the interest determination date relating to a particular interest period will be the second U.S. Government Securities Business Day prior to the applicable interest payment date (or, in the case of the final interest period, prior to the maturity date or if we elect to redeem in part or in full any series of notes, the redemption date for such notes);

●for USD SOFR ICE Swap Rate notes, the interest determination date relating to a particular interest reset date will be the number of Publication Calendar Days specified in the relevant pricing supplement;

●for treasury rate notes, the interest determination date relating to a particular interest reset date, which we refer to as a “treasury interest determination date,” will be the day of the week in which the interest reset date falls on which treasury bills — i.e., direct obligations of the U.S. government — would normally be auctioned. Treasury bills are usually sold at auction on Monday of each week, unless that day is a legal holiday, in which case the auction is usually held on the Tuesday of that week, except that the auction may be held on the preceding Friday. If as the result of a legal holiday an auction is held on the preceding Friday, that Friday will be the treasury interest determination date relating to the interest reset date occurring in the next succeeding week; and

●for CMT rate and CPI rate notes, the interest determination date relating to a particular interest reset date will be the second business day preceding the interest reset date.

The interest determination date pertaining to a floating rate note the interest rate of which is determined with reference to two or more interest rate bases (none of which is SOFR) will be the latest business day which is at least two business days before the related interest reset date for the applicable floating rate note on which each interest rate basis is determinable. The interest determination date pertaining to a floating rate note the interest rate of which is determined with reference to two or more interest rate bases (one of which is SOFR (exclusive of the USD SOFR ICE Swap Rate)) will be specified in the relevant pricing supplement.

Interest Calculation Dates. As described above, except for SOFR (exclusive of the USD SOFR ICE Swap Rate) notes, the interest rate that takes effect on a particular interest reset date will be determined by reference to the corresponding interest determination date. Except for EURIBOR notes and SOFR notes, however, the determination of the rate will actually be made on a day no later than the corresponding interest calculation date. The interest calculation date will be the earlier of the following:

●the tenth calendar day after the interest determination date or, if that tenth calendar day is not a business day, the next succeeding business day; and

S-24

●the business day immediately preceding the interest payment date or the maturity, whichever is the day on which the next payment of interest will be due.

The calculation agent need not wait until the relevant interest calculation date to determine the interest rate if the rate information it needs to make the determination is available from the relevant sources sooner.

Interest Payment Dates. The interest payment dates for a floating rate note will depend on when the interest rate is reset and, unless we specify otherwise in the relevant pricing supplement, will be as follows:

●for floating rate notes that reset daily, weekly or monthly, the third Wednesday of each month;

●for floating rate notes that reset quarterly, the third Wednesday of each of the four months of each year as specified in the relevant pricing supplement;

●for floating rate notes that reset semi-annually, the third Wednesday of each of the two months of each year as specified in the relevant pricing supplement; or

●for floating rate notes that reset annually, the third Wednesday of the month as specified in the relevant pricing supplement.

Regardless of these rules, if a note is originally issued after the regular record date and before the date that would otherwise be the first interest payment date, the first interest payment date will be the date that would otherwise be the second interest payment date.

In addition, the following special provision will apply to a floating rate note with regard to any interest payment date other than one that falls on the maturity date. If the interest payment date would otherwise fall on a day that is not a business day, then the interest payment date will be the next day that is a business day. If the maturity date of a floating rate note falls on a day that is not a business day, we will make the required payment of any principal, premium and interest on the next succeeding business day, and no additional interest will accrue in respect of the payment made on that next succeeding business day. However, unless otherwise specified in the relevant pricing supplement, if the floating rate note is a EURIBOR note or a SOFR note and the next business day falls in the next calendar month, then the interest payment date or the date that the payment of principal and any premium will be made will be the immediately preceding business day.

If any of the commercial paper rate, U.S. prime rate, treasury rate, CMT rate or federal funds rate have been discontinued, then the foregoing provisions concerning the calculation and payment of interest on commercial paper rate notes, U.S. prime rate notes, treasury rate notes, CMT rate notes or federal funds rate notes will be modified in accordance with the final paragraph in the description of each such rate below. The following are summaries of anticipated interest rate bases:

Commercial Paper Rate Notes

If you purchase a commercial paper rate note, your note will bear interest at an interest rate equal to the commercial paper rate and adjusted by the spread or spread multiplier, if any, indicated in the relevant pricing supplement.

Unless otherwise set forth in the relevant pricing supplement, the “commercial paper rate” will be the money market yield of the rate, for the relevant interest determination date, for commercial paper having the index maturity indicated in the relevant pricing supplement, as published in H.15 (as defined below) at 4:15 P.M., New York City time, on the relevant interest determination date under the heading “Commercial Paper — Nonfinancial.” If the commercial paper rate cannot be determined as described above, the following procedures will apply, unless specified otherwise in the relevant pricing supplement:

Temporary Non-Publication of the Commercial Paper Rate. Subject to the provisions below, if the commercial paper rate having such index maturity is not so published by the later of (i) 4:15 p.m., New York City time, on the relevant interest reset date and (ii) the next Business day, then the rate for that interest determination date will be last provided or published level of the commercial paper rate having such index maturity.

Index Cessation Event or Administrator/Benchmark Event. If an Index Cessation Event or an Administrator/Benchmark Event occurs with respect to the commercial paper rate, then, from and including the Index Cessation Effective Date or the Administrator/Benchmark Event Date, as applicable, the Alternative Post-nominated Index will apply to the commercial paper rate notes. However, if by 5:00 p.m., New York City time, on

S-25

the Cut-off Date, more than one Relevant Nominating Body formally designates, nominates or recommends an Alternative Post-nominated Index and those designations, nominations or recommendations are not the same, then the Calculation Agent Nominated Replacement Index will apply to the commercial paper rate notes.

In the event of a replacement of the commercial paper rate by either the Alternative Post-nominated Index or the Calculation Agent Nominated Replacement Index, the calculation agent shall (i) apply the Adjustment Spread (if applicable) to the Alternative Post-nominated Index or the Calculation Agent Nominated Replacement Index, as applicable, and (ii) after taking into account such Adjustment Spread, make any other adjustments to the terms of the notes that are necessary to account for the effect on the notes of referencing the Alternative Post-nominated Index or the Calculation Agent Nominated Replacement Index, as applicable.

The “money market yield” will be a yield calculated in accordance with the following formula:

where, “D” refers to the applicable per annum rate for commercial paper quoted on a bank discount basis and expressed as a decimal and “M” refers to the actual number of days in the interest payment period for which interest is being calculated.

U.S. Prime Rate Notes

If you purchase a U.S. prime rate note, your note will bear interest at an interest rate equal to the U.S. prime rate and adjusted by the spread or spread multiplier, if any, indicated in the relevant pricing supplement.

Unless otherwise set forth in the relevant pricing supplement, the “prime rate” will be the rate, for the relevant interest determination date, published in H.15 at 4:15 P.M., New York City time, on the relevant interest determination date opposite the heading “Bank prime loan.” If the U.S. prime rate cannot be determined as described above, the following procedures will apply, unless specified otherwise in the relevant pricing supplement:

Temporary Non-Publication of the Prime Rate. Subject to the provisions below, if the prime rate is not so published by the later of (i) 4:15 p.m., New York City time, on the relevant interest reset date and (ii) the next Business day, then the rate for that interest determination date will be last provided or published level of the prime rate.

Index Cessation Event or Administrator/Benchmark Event. If an Index Cessation Event or an Administrator/Benchmark Event occurs with respect to the prime rate, then, from and including the Index Cessation Effective Date or the Administrator/Benchmark Event Date, as applicable, the Alternative Post-nominated Index will apply to the prime rate notes. However, if by 5:00 p.m., New York City time, on the Cut-off Date, more than one Relevant Nominating Body formally designates, nominates or recommends an Alternative Post-nominated Index and those designations, nominations or recommendations are not the same, then the Calculation Agent Nominated Replacement Index will apply to the prime rate notes.

In the event of a replacement of the prime rate by either the Alternative Post-nominated Index or the Calculation Agent Nominated Replacement Index, the calculation agent shall (i) apply the Adjustment Spread (if applicable) to the Alternative Post-nominated Index or the Calculation Agent Nominated Replacement Index, as applicable, and (ii) after taking into account such Adjustment Spread, make any other adjustments to the terms of the notes that are necessary to account for the effect on the notes of referencing the Alternative Post-nominated Index or the Calculation Agent Nominated Replacement Index, as applicable.

EURIBOR Notes

If you purchase a EURIBOR note, your note will bear interest at an interest rate equal to EURIBOR and adjusted by the spread or spread multiplier, if any, indicated in the relevant pricing supplement.

Unless otherwise set forth in the relevant pricing supplement, “EURIBOR” means, for any interest determination date, the rate for deposits in euros as sponsored, calculated and published jointly by the European Banking Federation and ACI—The Financial Market Association, or any company established by the joint sponsors for purposes of establishing, compiling and publishing those rates, for the index maturity specified in the relevant pricing supplement as that rate appears on the display on LSEG on page EURIBOR01 or any successor page on

S-26

that service, which is commonly referred to as “LSEG page EURIBOR01,” as of 11:00 a.m., Brussels time. The following procedures will be followed if the rate cannot be determined as described above:

●If the above rate does not appear on the LSEG page EURIBOR01 as of 11:00 a.m., Brussels time, the calculation agent will request the principal euro-zone office of each of four major banks in the euro-zone interbank market, as selected by the calculation agent, after consultation with us, to provide the calculation agent with its offered rate for deposits in euros, at approximately 11:00 a.m., Brussels time, on the interest determination date, to prime banks in the euro-zone interbank market for the index maturity specified in the relevant pricing supplement commencing on the applicable interest reset date, and in a principal amount not less than the equivalent of US$1 million in euro that is representative of a single transaction in euro, in that market at that time. If two or more quotations are provided, EURIBOR will be the arithmetic mean of those quotations.

●If fewer than two quotations are provided as described above, EURIBOR will be the arithmetic mean of the rates quoted by four major banks in the euro-zone interbank market, as selected by the calculation agent, after consultation with us, at approximately 11:00 a.m., Brussels time, on the applicable interest reset date for loans in euro to leading European banks for a period of time equivalent to the index maturity specified in the relevant pricing supplement commencing on that interest reset date in a principal amount not less than the equivalent of US$1 million in euro that is representative of a single transaction in euro, in that market at that time.

No Index Cessation Effective Date with Respect to EURIBOR. If fewer than three banks so selected by the calculation agent are quoting as set forth above and, by 11:00 a.m., Brussels time (or the amended publication time for EURIBOR, if any, as specified by the EURIBOR benchmark administrator in the EURIBOR benchmark methodology), on the applicable interest reset date, EURIBOR for a period of the index maturity in respect of the related interest determination date has not been published on the LSEG page EURIBOR01 and an Index Cessation Effective Date has not occurred, then the rate for that interest reset date will be EURIBOR for a period of the index maturity in respect of the related index determination date, as provided by the administrator of EURIBOR and published by an authorized distributor or by the administrator of EURIBOR itself. If by 3:00 p.m., Brussels time (or four hours after the amended publication time for EURIBOR), on that interest reset date, neither the administrator of EURIBOR nor an authorized distributor has provided or published EURIBOR for a period of the index maturity in respect of such interest determination date and an Index Cessation Effective Date has not occurred, then, unless otherwise agreed by the parties, the rate for that interest reset date will be:

(A) a rate formally recommended for use by the administrator of EURIBOR; or 

(B) a rate formally recommended for use by the supervisor which is responsible for supervising EURIBOR or the administrator of EURIBOR, 

in each case, during the period of non-publication of EURIBOR and for so long as an Index Cessation Effective Date has not occurred. If a rate described in sub-paragraph (A) is available, that rate shall apply. If no such rate is available but a rate described in sub-paragraph (B) is available, that rate shall apply. If neither a rate described in sub-paragraph (A) nor a rate described in sub-paragraph (B) is available, then the calculation agent shall determine a commercially reasonable alternative for EURIBOR, taking into account any rate implemented by central counterparties and/or futures exchanges, in each case with trading volumes in derivatives or futures referencing EURIBOR that the calculation agent considers sufficient for that rate to be a representative alternative rate.

Index Cessation Effective Date with Respect to EURIBOR. Upon the occurrence of an Index Cessation Event, the rate for an interest reset date occurring two or more TARGET Settlement Days (as defined below) after the Index Cessation Effective Date will be determined as if references to EUR-EURIBOR-Reuters were references to Fallback Rate (EuroSTR) for the “Original IBOR Rate Record Day” (as that term is used on the Fallback Rate (EuroSTR) Screen) that corresponds to the related interest determination date, as most recently provided or published as at 11:30 a.m., Frankfurt time on the related Fallback Observation Day. If neither Bloomberg Index Services Limited (or a successor provider as approved and/or appointed by ISDA from time to time) provides, nor authorized distributors publish, Fallback Rate (EuroSTR) for that Original IBOR Rate Record Day at, or prior to, 11:30 a.m., Frankfurt time on the related Fallback Observation Day and a Fallback Index Cessation Effective Date with respect to Fallback Rate (EuroSTR) has not occurred, then the rate for the interest reset date will be Fallback

S-27

Rate (EuroSTR) as most recently provided or published at that time for the most recent Original IBOR Rate Record Day, notwithstanding that such day does not correspond to the related interest determination date.

Fallback Index Cessation Effective Date with Respect to Fallback Rate (EuroSTR). Upon the occurrence of a Fallback Index Cessation Event with respect to Fallback Rate (EuroSTR), the rate for an interest reset date which relates to an interest period (or any compounding period included in that interest period) in respect of which the Fallback Observation Day occurs on or after the Fallback Index Cessation Effective Date with respect to Fallback Rate (EuroSTR) will be the Euro Short-Term Rate (“EuroSTR”) administered by the European Central Bank (or any successor administrator), to which the calculation agent shall apply the most recently published spread, as at the Fallback Index Cessation Effective Date with respect to Fallback Rate (EuroSTR), referred to in the definition of “Fallback Rate (EuroSTR)” after making such adjustments to EuroSTR as are necessary to account for any difference in term structure or tenor of EuroSTR by comparison to Fallback Rate (EuroSTR) and by reference to the Bloomberg IBOR Fallback Rate Adjustments Rule Book.

No Fallback Index Cessation Effective Date with Respect to EuroSTR. If neither the administrator nor authorized distributors provide or publish EuroSTR and a Fallback Index Cessation Effective Date with respect to EuroSTR has not occurred, then, in respect of any day for which EuroSTR is required, references to EuroSTR will be deemed to be references to the last provided or published EuroSTR.

Fallback Index Cessation Effective Date with Respect to EuroSTR. If a Fallback Index Cessation Effective Date occurs with respect to each of Fallback Rate (EuroSTR) and EuroSTR, then the rate for an interest reset date which relates to an interest period (or any compounding period included in that interest period) in respect of which the Fallback Observation Day occurs on or after the Fallback Index Cessation Effective Date with respect to Fallback Rate (EuroSTR) (or, if later, the Fallback Index Cessation Effective Date with respect to EuroSTR) will be the ECB Recommended Rate, to which the calculation agent shall apply the most recently published spread, as at the Fallback Index Cessation Effective Date with respect to Fallback Rate (EuroSTR), referred to in the definition of “Fallback Rate (EuroSTR)” after making such adjustments to the ECB Recommended Rate as are necessary to account for any difference in term structure or tenor of the ECB Recommended Rate by comparison to Fallback Rate (EuroSTR) and by reference to the Bloomberg IBOR Fallback Rate Adjustments Rule Book.

No Fallback Index Cessation Effective Date with Respect to ECB Recommended Rate. If there is an ECB Recommended Rate before the end of the first TARGET Settlement Day following the Fallback Index Cessation Effective Date with respect to Fallback Rate (EuroSTR) (or, if later, the end of the first TARGET Settlement Day following the Fallback Index Cessation Effective Date with respect to EuroSTR) but neither the administrator nor authorized distributors provide or publish the ECB Recommended Rate and a Fallback Index Cessation Effective Date with respect to it has not occurred, then, in respect of any day for which the ECB Recommended Rate is required, references to the ECB Recommended Rate will be deemed to be references to the last provided or published ECB Recommended Rate.

No ECB Recommended Rate or Fallback Index Cessation Effective Date with Respect to ECB Recommended Rate. If:

(A) no ECB Recommended Rate is recommended before the end of the first TARGET Settlement Day following the Fallback Index Cessation Effective Date with respect to Fallback Rate (EuroSTR) (or, if later, the end of the first TARGET Settlement Day following the Fallback Index Cessation Effective Date with respect to EuroSTR); or

(B) a Fallback Index Cessation Effective Date with respect to the ECB Recommended Rate subsequently occurs, 

then the rate for an interest reset date which relates to an interest period (or any compounding period included in that interest period) in respect of which the Fallback Observation Day occurs on or after the Fallback Index Cessation Effective Date with respect to Fallback Rate (EuroSTR) (or, if later, the Fallback Index Cessation Effective Date with respect to EuroSTR) or the Fallback Index Cessation Effective Date with respect to the ECB Recommended Rate (as applicable) will be Modified EDFR, to which the calculation agent shall apply the most recently published spread, as at the Fallback Index Cessation Effective Date with respect to Fallback Rate (EuroSTR), referred to in the definition of “Fallback Rate (EuroSTR)” after making such adjustments to Modified EDFR as are necessary to account for any difference in term structure or tenor of Modified EDFR by comparison to Fallback Rate (EuroSTR) and by reference to the Bloomberg IBOR Fallback Rate Adjustments Rule Book.

S-28

No Fallback Index Cessation Effective Date with Respect to Modified EDFR. If neither the administrator nor authorized distributors provide or publish Modified EDFR (or the index, benchmark or other price source that is referred to in the definition of Modified EDFR) and a Fallback Index Cessation Effective Date with respect to that rate has not occurred, then, in respect of any day for which that rate is required, references to that rate will be deemed to be references to the last provided or published Modified EDFR (or the last provided or published index, benchmark or other price source that is referred to in the definition of Modified EDFR).

“Index Cessation Event” with respect to EURIBOR means: 

(i) a public statement or publication of information by or on behalf of the administrator of EURIBOR announcing that it has ceased or will cease to provide EURIBOR permanently or indefinitely, provided that, at the time of the statement or publication, there is no successor administrator that will continue to provide EURIBOR; or

(ii) a public statement or publication of information by the regulatory supervisor for the administrator of EURIBOR, the central bank for Euro, an insolvency official with jurisdiction over the administrator for EURIBOR, a resolution authority with jurisdiction over the administrator for EURIBOR or a court or an entity with similar insolvency or resolution authority over the administrator for EURIBOR, which states that the administrator of EURIBOR has ceased or will cease to provide EURIBOR permanently or indefinitely, provided that, at the time of the statement or publication, there is no successor administrator that will continue to provide EURIBOR.

“Index Cessation Effective Date” means, in respect of EURIBOR and one or more Index Cessation Events, the first date on which EURIBOR is no longer provided. If EURIBOR ceases to be provided on the relevant interest determination date but it was provided at the time at which it is to be observed pursuant to the provisions of “—Index Cessation Effective Date with respect to EURIBOR” above, then the Index Cessation Effective Date will be the next day on which the rate would ordinarily have been published.

“Fallback Index Cessation Event” means, in respect of Fallback Rate (EuroSTR):

If the Applicable Fallback Rate is Modified EDFR, references to the administrator or provider of such rate in this definition of “Fallback Index Cessation Event” shall be deemed to be references to the administrator or provider of the index, benchmark or other price source that is referred to in the definition of Modified EDFR.

“Fallback Index Cessation Effective Date” means, in respect of a Fallback Index Cessation Event, the first date on which the Applicable Fallback Rate is no longer provided. If the Applicable Fallback Rate ceases to be provided on the same day that it is required to determine the rate for an interest reset date pursuant to the terms of

the relevant “—Fallback Index Cessation Event” provisions above but it was provided at the time at which it is to be observed pursuant to the terms of the such relevant provision (or, if no such time is specified in such relevant provision, at the time at which it is ordinarily published), then the Fallback Index Cessation Effective Date will be the next day on which the rate would ordinarily have been published. If the Applicable Fallback Rate is Modified EDFR, references to the Applicable Fallback Rate in this definition of “Fallback Index Cessation Effective Date” shall be deemed to be references to the index, benchmark or other price source that is referred to in the definition of Modified EDFR.

SOFR Notes

If you purchase a SOFR note, your note will bear interest at a base rate equal to SOFR as adjusted by the spread or spread multiplier, if any, specified in the applicable pricing supplement.

The Secured Overnight Financing Rate. SOFR is published by the SOFR Administrator and is intended to be a broad measure of the cost of borrowing cash overnight collateralized by U.S. Treasury securities. The SOFR Administrator reports that SOFR includes all trades in the Broad General Collateral Rate and bilateral U.S. Treasury repurchase agreement (repo) transactions cleared through the delivery-versus-payment service offered by the Fixed Income Clearing Corporation (the “FICC”), a subsidiary of DTC, and SOFR is filtered by the SOFR Administrator to remove some (but not all) of the foregoing transactions considered to be “specials.” According to the SOFR Administrator, “specials” are repos for specific-issue collateral, which take place at cash-lending rates below those for general collateral repos because cash providers are willing to accept a lesser return on their cash in order to obtain a particular security.

The SOFR Administrator reports that SOFR is calculated as a volume-weighted median of transaction-level tri-party repo data collected from The Bank of New York Mellon as well as General Collateral Finance Repo transaction data and data on bilateral U.S. Treasury repo transactions cleared through the FICC’s delivery-versus-payment service. The SOFR Administrator also notes that it obtains information from DTCC Solutions LLC, an affiliate of DTC.

If data for a given market segment were unavailable for any day, then the most recently available data for that segment would be utilized, with the rates on each transaction from that day adjusted to account for any change in the level of market rates in that segment over the intervening period. SOFR would be calculated from this adjusted prior day’s data for segments where current data were unavailable, and unadjusted data for any segments where data were available. To determine the change in the level of market rates over the intervening period for the missing market segment, the SOFR Administrator would use information collected through a daily survey conducted by its Trading Desk of primary dealers’ repo borrowing activity.

The SOFR Administrator notes on its publication page for SOFR that use of SOFR is subject to important limitations, indemnification obligations and disclaimers, including that the SOFR Administrator may alter the methods of calculation, publication schedule, rate revision practices or availability of SOFR at any time without notice.

Each U.S. Government Securities Business Day, the SOFR Administrator publishes SOFR on its website at approximately 8:00 a.m., New York City time. If errors are discovered in the transaction data provided by The Bank of New York Mellon or DTCC Solutions LLC, or in the calculation process, subsequent to the initial publication of SOFR but on that same day, SOFR and the accompanying summary statistics may be republished at approximately 2:30 p.m., New York City time. Additionally, if transaction data from The Bank of New York Mellon or DTCC Solutions LLC had previously not been available in time for publication, but became available later in the day, the affected rate or rates may be republished at around this time. Rate revisions will only be effected on the same day as initial publication and will only be republished if the change in the rate exceeds one basis point. Any time a rate is revised, a footnote to the SOFR Administrator’s publication would indicate the revision. This revision threshold will be reviewed periodically by the SOFR Administrator and may be changed based on market conditions.

Because SOFR is published by the SOFR Administrator based on data received from other sources, we have no control over its determination, calculation or publication.

The information contained in this “The Secured Overnight Financing Rate” section is based upon the SOFR Administrator’s website and other U.S. government sources.

SOFR notes will be either Compounded SOFR notes with Lookback, Compounded SOFR notes with Observation Period Shift, Compounded SOFR notes with Payment Delay, Compounded SOFR Index notes with Observation Period Shift, Average SOFR Notes with Lookback, Average SOFR Notes with Observation Period

S-31

Shift or Weighted Average SOFR notes, each as indicated in the applicable pricing supplement and as described below.

The interest rate applicable for an interest period will be determined on the applicable Interest Payment Determination Date, except that the interest rate for Compounded SOFR notes with Payment Delay will be determined on the applicable Interest Accrual Period End Date, with the interest rate for the final Interest Accrual Period being determined on the Rate Cut-Off Date.

The amount of interest accrued and payable on the SOFR notes for each interest period will be calculated by the calculation agent and will be equal to the product of (i) the outstanding principal amount of the SOFR notes multiplied by (ii) the product of (a) the base rate plus the applicable spread or multiplied by the applicable spread multiplier for the relevant interest period multiplied by (b) the day count fraction. The day count fraction for all Compounded SOFR notes is Actual/360, being the actual number of calendar days in the interest period divided by 360, provided that for Compounded SOFR notes with Payment Delay, this calculation will be made in respect of each Interest Accrual Period, rather than each interest period.

The Interest Payment Determination Date for Compounded SOFR notes with Lookback, Compounded SOFR notes with Observation Period Shift, Compounded SOFR Index notes with Observation Period Shift, Average SOFR Notes with Lookback and Average SOFR Notes with Observation Period Shift means the day that is the number of U.S. Government Securities Business Days prior to the Interest Payment Date in respect of the relevant interest period, as specified in the applicable pricing supplement. The Interest Payment Determination Date for Compounded SOFR notes with Payment Delay is the Interest Accrual Period End Date at the end of each Interest Accrual Period; provided that the Interest Payment Determination Date with respect to the final Interest Accrual Period will be the Rate Cut-Off Date.

For Compounded SOFR notes with Lookback, Compounded SOFR notes with Observation Period Shift, Compounded SOFR Index notes with Observation Period Shift, Average SOFR Notes with Lookback and Average SOFR Notes with Observation Period Shift, if any scheduled Interest Payment Date, other than the maturity date or redemption date, if applicable, falls on a day that is not a business day, such date will be postponed to the following business day, except that, if that business day would fall in the next calendar month, the Interest Payment Date will be the immediately preceding business day. If the scheduled final Interest Payment Date (i.e., the maturity date or any redemption date) falls on a day that is not a business day, the payment of principal and interest will be made on the next succeeding business day, but the final Interest Payment Date will not be postponed and interest on that payment will not accrue during the period from and after the scheduled final Interest Payment Date.  For Compounded SOFR notes with Payment Delay, if any scheduled Interest Accrual Period End Date falls on a day that is not a business day, such date will be postponed to the following business day, except that, if that business day would fall in the next calendar month, the Interest Accrual Period End Date will be the immediately preceding business day.

Effect of a Benchmark Transition Event for Compounded SOFR Notes

If we or our Designee (as defined below) determine on or prior to the relevant Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to the then-current Benchmark, the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the SOFR notes in respect of all determinations on such date and for all determinations on all subsequent dates.

In connection with the implementation of a Benchmark Replacement, we or our Designee will have the right to make Benchmark Replacement Conforming Changes from time to time.

Any determination, decision or election that may be made by us or our Designee pursuant to this section, including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection:

(1)will be conclusive and binding absent manifest error;

(2)will be made in our or our Designee’s sole discretion, as applicable; and

(3)notwithstanding anything to the contrary in the indenture or the SOFR notes, shall become effective without consent from the Holders or any other party.

S-36

“Benchmark” means, initially, the base rate (Compounded SOFR, Average SOFR or Weighted Average SOFR, as applicable) as specified in the applicable pricing supplement, as such terms are defined above; provided that if we or our Designee determine on or prior to the Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to the base rate (or the published daily SOFR used in the calculation thereof) or the then-current Benchmark, then “Benchmark” means the applicable Benchmark Replacement.

“Benchmark Replacement” means the first alternative set forth in the order below that can be determined by us or our Designee as of the Benchmark Replacement Date.

(1)the sum of: (a) the alternate rate of interest that has been selected or recommended by the Relevant Governmental Body as the replacement for the then-current Benchmark and (b) the Benchmark Replacement Adjustment;

(2)the sum of: (a) the ISDA Fallback Rate and (b) the Benchmark Replacement Adjustment; or

(3)the sum of: (a) the alternate rate of interest that has been selected by us or our Designee as the replacement for the then-current Benchmark giving due consideration to any industry-accepted rate of interest as a replacement for the then-current Benchmark for U.S. dollar-denominated floating rate notes at such time and (b) the Benchmark Replacement Adjustment.

“Benchmark Replacement Adjustment” means the first alternative set forth in the order below that can be determined by us or our Designee as of the Benchmark Replacement Date:

(1)the spread adjustment, or method for calculating or determining such spread adjustment, (which may be a positive or negative value or zero) that has been selected or recommended by the Relevant Governmental Body for the applicable Unadjusted Benchmark Replacement;

(2)if the applicable Unadjusted Benchmark Replacement is equivalent to the ISDA Fallback Rate, the ISDA Fallback Adjustment; or

(3)the spread adjustment (which may be a positive or negative value or zero) that has been selected by us or our Designee giving due consideration to any industry-accepted spread adjustment, or method for calculating or determining such spread adjustment, for the replacement of the then-current Benchmark with the applicable Unadjusted Benchmark Replacement for U.S. dollar-denominated floating rate notes at such time.

“Benchmark Replacement Conforming Changes” means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the timing and frequency of determining rates and making payments of interest, rounding of amounts or tenors, and other administrative matters) that we or our Designee decides may be appropriate to reflect the adoption of such Benchmark Replacement in a manner substantially consistent with market practice (or, if we or our Designee decides that adoption of any portion of such market practice is not administratively feasible or if we or our Designee determine that no market practice for use of the Benchmark Replacement exists, in such other manner as we or our Designee determine is reasonably necessary).

“Benchmark Replacement Date” means the earliest to occur of the following events with respect to the then-current Benchmark (including the daily published component used in the calculation thereof):

(1)in the case of clause (1) or (2) of the definition of “Benchmark Transition Event,” the later of (a) the date of the public statement or publication of information referenced therein and (b) the date on which the administrator of the Benchmark permanently or indefinitely ceases to provide the Benchmark (or such component); or

(2)in the case of clause (3) of the definition of “Benchmark Transition Event,” the date of the public statement or publication of information referenced therein.

For the avoidance of doubt, if the event that gives rise to the Benchmark Replacement Date occurs on the same day as, but earlier than, the Reference Time in respect of any determination, the Benchmark Replacement Date will be deemed to have occurred prior to the Reference Time for such determination.

“Benchmark Transition Event” means the occurrence of one or more of the following events with respect to the then-current Benchmark (including the daily published component used in the calculation thereof):

S-37

(3)a public statement or publication of information by the regulatory supervisor for the administrator of the Benchmark announcing that the Benchmark is no longer representative.

“ISDA Definitions” means the 2021 ISDA Definitions published by the International Swaps and Derivatives Association, Inc. or any successor thereto, as amended or supplemented from time to time, or any successor definitional booklet for interest rate derivatives published from time to time.

“ISDA Fallback Adjustment” means the spread adjustment (which may be a positive or negative value or zero) that would apply for derivatives transactions referencing the ISDA Definitions to be determined upon the occurrence of an index cessation event with respect to the Benchmark.

“ISDA Fallback Rate” means the rate that would apply for derivatives transactions referencing the ISDA Definitions to be effective upon the occurrence of an index cessation date with respect to the Benchmark for the applicable tenor excluding the applicable ISDA Fallback Adjustment.

“Reference Time” with respect to any determination of the Benchmark means (1) if the Benchmark is Compounded SOFR or Weighted Average SOFR, the SOFR Determination Time, (2) if the Benchmark is Compounded SOFR Index, the SOFR Index Determination Time; and (3) if the Benchmark is not Compounded SOFR, Weighted Average SOFR or Compounded SOFR Index, the time determined by us or our Designee after giving effect to the Benchmark Replacement Conforming Changes.

“Relevant Governmental Body” means the Federal Reserve Board and/or the Federal Reserve Bank of New York, or a committee officially endorsed or convened by the Federal Reserve Board and/or the Federal Reserve Bank of New York or any successor thereto.

“Unadjusted Benchmark Replacement” means the Benchmark Replacement excluding the Benchmark Replacement Adjustment.

Weighted Average SOFR Notes

“Weighted Average SOFR” means the arithmetic mean of SOFR in effect for each business day during the relevant interest period, calculated by multiplying the relevant SOFR by the number of calendar days such SOFR is in effect, determining the sum of such products and dividing such sum by the number of calendar days in the relevant interest period, provided however that during a Suspension Period, the SOFR for each day during that Suspension Period will be the value for the business day immediately prior to the first day of such Suspension Period.  For purposes of this provision “Suspension Period” is the number of business days prior to the end of the relevant interest period as specified in the applicable pricing supplement.

USD SOFR ICE Swap Rate

If you purchase a USD SOFR ICE Swap Rate note, your note will bear interest at an interest rate equal to the USD SOFR ICE Swap Rate and adjusted by the spread or spread multiplier, if any, indicated in the relevant pricing supplement.

The USD SOFR ICE Swap Rate for any U.S. Government Securities Business Day for the applicable index maturity is the SOFR-linked interest rate swap, as published on the ICE Benchmark Administration Limited (“ICE”)

S-38

website opposite the heading for that Index Maturity at approximately 11:00 a.m., New York City time, on the applicable Publication Calendar Day. The USD SOFR ICE Swap Rate for that index maturity measures the fixed rate of interest payable on a hypothetical fixed-for-floating SOFR interest rate swap transaction with a maturity matching the index maturity. In such a hypothetical swap transaction, the fixed rate of interest, payable annually on the basis of the actual number of days in the relevant year over 360, is exchangeable for a floating payment stream of SOFR compounded in arrears for twelve months using standard market conventions.

Temporary non-publication of USD SOFR ICE Swap Rate.  Subject to the provisions below, if the USD SOFR ICE Swap Rate is not published by the later of (i) 11:00 a.m., New York City time, on the interest determination date and (ii) the related interest reset date, then the calculation agent shall determine a commercially reasonable alternative for the USD SOFR ICE Swap Rate, taking into account all available information that in good faith it considers relevant including a rate implemented by central counterparties and/or futures exchanges (if any), in each case with trading volumes in derivatives or futures referencing the USD SOFR ICE Swap Rate that the calculation agent considers sufficient for that rate to be a representative alternative rate.

Index Cessation Event or Administrator/Benchmark Event. If an Index Cessation Event or an Administrator/Benchmark Event occurs with respect to USD SOFR ICE Swap Rate, then, from and including the Index Cessation Effective Date or the Administrator/Benchmark Event Date, as applicable, the Alternative Post-nominated Index will apply to the USD SOFR ICE Swap Rate notes. However, if by 5:00 p.m., New York City time, on the Cut-off Date, more than one Relevant Nominating Body formally designates, nominates or recommends an Alternative Post-nominated Index and those designations, nominations or recommendations are not the same, then the Calculation Agent Nominated Replacement Index will apply to the USD SOFR ICE Swap Rate notes. 

In the event of a replacement of USD SOFR ICE Swap Rate by either the Alternative Post-nominated Index rate or the Calculation Agent Nominated Replacement Index, the calculation agent shall (i) apply the Adjustment Spread (if applicable) to the Alternative Post-nominated Index rate or the Calculation Agent Nominated Replacement Index, as applicable, and (ii) after taking into account such Adjustment Spread, make any other adjustments to the terms of the USD SOFR ICE Swap Rate notes that are necessary to account for the effect on the USD SOFR ICE Swap Rate notes of referencing the Alternative Post-nominated Index rate or the Calculation Agent Nominated Replacement Index, as applicable.

Whenever the calculation agent is required to act, make a determination or exercise judgement pursuant to a replacement of USD SOFR ICE Swap Rate by either the Alternative Post-nominated Index or the Calculation Agent Nominated Replacement Index, it shall do so by reference to Relevant Market Data available at, or a reasonable period of time prior to, the time of notification.  The calculation agent shall notify CIBC of any determination it makes pursuant to the replacement of USD SOFR ICE Swap Rate by either the Alternative Post-nominated Index or the Calculation Agent Nominated Replacement Index as soon as reasonably practicable after either of these replacement rates first apply and, in any event, at least two Business Days before the Cut-off Date. However, any failure to provide such a notification shall not give rise to an Event of Default (as defined in the indenture).

Certain defined terms, as used with respect to the USD SOFR ICE Swap Rate, the CMT rate, the commercial paper rate, the federal funds rate, the prime rate and the treasury rate:

“Adjustment Spread” means the adjustment, if any, determined by the calculation agent in its sole discretion, which is required in order to reduce or eliminate, to the extent reasonably practicable, any transfer of economic value from (i) us to the holders of the floating-rate notes with a base rate that is an Applicable Benchmark or (ii) the holders of the floating-rate notes with a base rate that is an Applicable Benchmark to CIBC, in each case, that would otherwise arise as a result of the replacement made pursuant to the application of the Calculation Agent Nominated Replacement Index or the Alternative Post-nominated Index. Any such adjustment may take account of, without limitation, any anticipated transfer of economic value as a result of any difference in the term structure or tenor of the Calculation Agent Nominated Replacement Index or the Alternative Post-nominated Index by comparison to the Applicable Benchmark. The Adjustment Spread may be positive, negative or zero or determined pursuant to a formula or methodology.

“Administrator” means, as applicable, (i) the Board of Governors of the Federal Reserve System for each of the CMT rate, the commercial paper rate, the prime rate and the treasury rate, (ii) the New York Federal Reserve for the federal funds rate and (iii) ICE for the USD SOFR ICE Swap Rate.

S-39

“Administrator/Benchmark Event” means the delivery of a notice by CIBC to the holders of the floating rate notes with a base rate that is an Applicable Benchmark (which can include posting of such notice through DTC) specifying, and citing Publicly Available Information that reasonably confirms, an event or circumstance which has the effect that CIBC or the calculation agent are not, or will not be, permitted under any applicable law or regulation to use the Applicable Benchmark to perform our or its respective obligations under the terms of such notes.

“Administrator/Benchmark Event Date” means, in respect of an Administrator/Benchmark Event, the date from which the Applicable Benchmark may no longer be used under any applicable law or regulation by CIBC or the calculation agent or, if that date occurs before the issue date, the issue date.

“Alternative Post-nominated Index” means, in respect of an Applicable Benchmark, any index, benchmark or other price source which is formally designated, nominated or recommended by: (i) any Relevant Nominating Body; or (ii) the Administrator or sponsor of the Applicable Benchmark, provided that such index, benchmark or other price source is substantially the same as the Applicable Benchmark, in each case, to replace the Applicable Benchmark. If a replacement is designated, nominated or recommended under both clauses (i) and (ii) above, then the replacement under clause (i) above shall be the “Alternative Post-nominated Index.”

“Applicable Benchmark” means the USD SOFR ICE Swap Rate, the CMT rate, the commercial paper rate, the federal funds rate, the prime rate or the treasury rate, as applicable.

“Calculation Agent Nominated Replacement Index” means, in respect of an Applicable Benchmark, the index, benchmark or other price source that the calculation agent determines to be a commercially reasonable alternative for the Applicable Benchmark.

“Cut-off Date” means fifteen Business Days following the Administrator/Benchmark Event Date. However, if more than one Relevant Nominating Body formally designates, nominates or recommends an Alternative Post-nominated Index or a spread or methodology for calculating a spread and one or more of those Relevant Nominating Bodies does so on or after the day that is three Business Days before that date, then the Cut-off Date will instead be the second Business Day following the date that, but for this sentence, would have been the Cut-off Date.

“Index Cessation Effective Date” means, with respect to one or more Index Cessation Events, the first date on which the Applicable Benchmark would ordinarily have been published or provided and is no longer published or provided.

“Index Cessation Event” means, with respect to an Applicable Benchmark, (a) a public statement or publication of information by or on behalf of the Administrator of the Applicable Benchmark announcing that it has ceased or will cease to provide the Applicable Benchmark permanently or indefinitely, provided that, at the time of the statement or publication, there is no successor administrator or provider, as applicable, that will continue to provide the Applicable Benchmark; or (b) a public statement or publication of information by the regulatory supervisor for the Administrator of the Applicable Benchmark, the central bank for the currency of the Applicable Benchmark, an insolvency official with jurisdiction over the Administrator for the Applicable Benchmark, a resolution authority with jurisdiction over the Administrator for the Applicable Benchmark or a court or an entity with similar insolvency or resolution authority over the Administrator for the Applicable Benchmark, which states that the Administrator of the Applicable Benchmark has ceased or will cease to provide the Applicable Benchmark permanently or indefinitely, provided that, at the time of the statement or publication, there is no successor administrator or provider that will continue to provide the Applicable Benchmark.

A “Publication Calendar Day” is any day on which the Administrator is due to publish the rate for the Applicable Benchmark pursuant to its publication calendar, as updated from time to time.

“Publicly Available Information” means, in respect of an Administrator/Benchmark Event, one or both of the following: (a) information received from or published by (i) the Administrator or sponsor of the Applicable Benchmark or (ii) any national, regional or other supervisory or regulatory authority which is responsible for supervising the Administrator or sponsor of the Applicable Benchmark or regulating the Applicable Benchmark. However, where any information of the type described in (i) or (ii) is not publicly available, it shall only constitute Publicly Available Information if it can be made public without violating any law, regulation, agreement, understanding or other restriction regarding the confidentiality of that information; or (b) information published in a Specified Public Source (regardless of whether the reader or user thereof pays a fee to obtain that information).

S-40

“Relevant Market Data” means, in relation to a determination, any relevant information that: (i) has been supplied by one or more third parties (which may include central counterparties, exchanges, dealers in the relevant market, information vendors, brokers or other recognized sources of market information) but not any third party that is an affiliate of the calculation agent or (ii) to the extent that the information is not readily available from such third parties or would not produce a commercially reasonable result, has been obtained from internal sources (which may include an affiliate of the calculation agent, provided that the information is of the same type as that used by the calculation agent in a comparable manner in the ordinary course of its business).

“Relevant Nominating Body” means (i) the Board of Governors of the Federal Reserve System or any central bank or other supervisor which is responsible for supervising either the Applicable Benchmark or the Administrator; or (ii) any working group or committee officially endorsed or convened by: (a) the Board of Governors of the Federal Reserve System; (b) any central bank or other supervisor which is responsible for supervising either the Applicable Benchmark or the Administrator; (c) a group of those central banks or other supervisors; or (d) the Financial Stability Board or any part thereof.

Treasury Rate Notes

If you purchase a treasury rate note, your note will bear interest at an interest rate equal to the treasury rate and adjusted by the spread or spread multiplier, if any, indicated in the relevant pricing supplement.

Unless otherwise set forth in the relevant pricing supplement, the “treasury rate” means the rate for the auction, on the relevant treasury interest determination date, of treasury bills having the index maturity specified in the relevant pricing supplement, as that rate appears on the LSEG page USAUCTION10 or USAUCTION11 under the heading “INVEST RATE” by 3:00 P.M., New York City time, on the relevant treasury interest determination date. If the treasury rate cannot be determined in this manner, the following procedures will apply, unless specified otherwise in the relevant pricing supplement:

●If the rate described above does not appear on either page at 3:00 P.M., New York City time, on the relevant treasury interest determination date, unless the calculation is made earlier and the rate is available from that source at that time, the treasury rate will be the bond equivalent yield of the rate, for the relevant treasury interest determination date, for the type of treasury bill described above, as announced by the U.S. Department of the Treasury.

●If the auction rate described in the prior paragraph is not so announced by 3:00 P.M., New York City time, on the relevant treasury interest determination date, or if no such auction is held for the relevant week, then the treasury rate will be the bond equivalent yield of the rate, for the relevant treasury interest determination date and for treasury bills having the specified index maturity, as published in H.15 under the heading “U.S. government securities/Treasury bills (secondary market).”

●if the rate referred to in the prior paragraph is not so published by 3:00 p.m., New York City time, on the related calculation date, the rate on the applicable interest determination date calculated by the calculation agent as the bond equivalent yield of the arithmetic mean of the secondary market bid rates, as of approximately 3:30 p.m., New York City time, on the applicable interest determination date, of three primary U.S. government securities dealers, which may include the agents and their affiliates, selected by the calculation agent, for the issue of Treasury Bills with a remaining maturity closest to the index maturity specified in the applicable pricing supplement. 

Index Cessation Event or Administrator/Benchmark Event. If an Index Cessation Event or an Administrator/Benchmark Event occurs with respect to the treasury rate, then, from and including the Index Cessation Effective Date or the Administrator/Benchmark Event Date, as applicable, the Alternative Post-nominated Index will apply to the treasury rate notes. However, if by 5:00 p.m., New York City time, on the Cut-off Date, more than one Relevant Nominating Body formally designates, nominates or recommends an Alternative Post-nominated

S-41

Index and those designations, nominations or recommendations are not the same, then the Calculation Agent Nominated Replacement Index will apply to the treasury rate notes.

In the event of a replacement of the treasury rate by either the Alternative Post-nominated Index or the Calculation Agent Nominated Replacement Index, the calculation agent shall (i) apply the Adjustment Spread (if applicable) to the Alternative Post-nominated Index or the Calculation Agent Nominated Replacement Index, as applicable, and (ii) after taking into account such Adjustment Spread, make any other adjustments to the terms of the notes that are necessary to account for the effect on the notes of referencing the Alternative Post-nominated Index or the Calculation Agent Nominated Replacement Index, as applicable.

The “bond equivalent yield” means a yield calculated in accordance with the following formula and expressed as a percentage:

where, “D” refers to the applicable per annum rate for Treasury Bills quoted on a bank discount basis, “N” refers to 365 or 366, as applicable, and “M” refers to the actual number of days in the interest payment period for which interest is being calculated.

CMT Rate Notes

If you purchase a CMT rate note, your note will bear interest at an interest rate equal to the CMT rate and adjusted by the spread or spread multiplier, if any, indicated in the relevant pricing supplement.

Unless otherwise set forth in the relevant pricing supplement, the “CMT rate” means the rate as set forth in H.15 (as defined below), opposite the caption “Treasury constant maturities” for the Designated CMT Index Maturity, as that rate is published on the Designated CMT LSEG page, for:

●that interest determination date, if the Designated CMT LSEG page (as defined below) is FRBCMT; and

●the week or the month, as applicable, ended immediately preceding the week or month in which the related interest reset date occurs, if the Designated CMT LSEG page is FEDCMT.

The following procedures will be followed if the CMT rate cannot be determined as described above:

●If the applicable CMT rate is FRBCMT and that rate is not displayed on the relevant Designated CMT LSEG page by 4:15 p.m., New York City time, on the related interest determination date, then the CMT rate for the related interest reset date will be a percentage equal to the yield for U.S. Treasury securities at “constant maturity” for the Designated CMT Index Maturity on the related interest reset date as set forth in H.15 under the caption “Treasury constant maturities.”

●If the applicable CMT rate is FEDCMT and that rate is not displayed on the relevant Designated CMT LSEG page by 4:15 p.m., New York City time, on the related interest reset date, then the CMT rate for the related interest reset date will be a percentage equal to the one-week average yield for U.S. Treasury securities at “constant maturity” for the Designated CMT Index Maturity and for the week preceding the related interest reset date as set forth in H.15 opposite the caption “Treasury constant maturities.”

●If the applicable rate described above is FRBCMT and that rate does not appear in H.15, then the CMT rate for the related interest reset date will be the rate for the Designated CMT Index Maturity as may then be published by either the Board of Governors of the Federal Reserve System or the U.S. Department of the Treasury that the calculation agent determines to be comparable to the rate that would otherwise have been published in H.15.

●If the applicable rate described above is FEDCMT and that rate does not appear in H.15, then the CMT rate for the related interest reset date will be the one-week or one-month, as applicable, average yield for U.S. Treasury securities at “constant maturity” for the Designated CMT Index Maturity as otherwise announced by the Federal Reserve Bank of New York for the week or month, as applicable, preceding that interest reset date.

S-42

●If none of the Board of Governors of the Federal Reserve System, the U.S. Department of the Treasury or the Federal Reserve Bank of New York publishes a yield on U.S. Treasury securities at a “constant maturity” for the Designated CMT Index Maturity, as described in the two preceding paragraphs, then the applicable CMT rate on the related interest reset date will be calculated by the calculation agent and will be a yield-to-maturity based on the arithmetic mean of the secondary market bid prices at approximately 3:30 p.m., New York City time, on the related interest determination date, of three leading primary U.S. government securities dealers in New York City. The calculation agent will select five such securities dealers, and will eliminate the highest quotation (or, in the event of equality, one of the highest) and the lowest quotation (or, in the event of equality, one of the lowest), for U.S. Treasury securities with an original maturity equal to the Designated CMT Index Maturity, a remaining term to maturity of no more than one year shorter than that Designated CMT Index Maturity and in a principal amount equal to the Representative Amount.

●If fewer than five but more than two such prices are provided as requested, the CMT rate for the related interest reset date will be based on the arithmetic mean of the bid prices obtained and neither the highest nor the lowest of those quotations will be eliminated.

●If the calculation agent cannot obtain three U.S. Treasury securities quotations of the kind requested in the prior two paragraphs, the calculation agent will determine the applicable CMT rate to be the yield to maturity based on the arithmetic mean of the secondary market bid prices for U.S. Treasury securities, at approximately 3:30 p.m., New York City time, on the related interest determination date of three leading primary U.S. government securities dealers in New York City. In selecting these bid prices, the calculation agent will request quotations from at least five of those securities dealers and will disregard the highest quotation (or if there is equality, one of the highest) and the lowest quotation (or if there is equality, one of the lowest) for U.S. Treasury securities with an original maturity greater than the Designated CMT Index Maturity, a remaining term to maturity closest to the Designated CMT Index Maturity and in a Representative Amount.

●If fewer than five but more than two of the leading primary U.S. government securities dealers provide quotes as described in the prior paragraph, then the applicable CMT rate will be based on the arithmetic mean of the bid prices obtained, and neither the highest nor the lowest of those quotations will be eliminated.

●If two bid prices with an original maturity as described above have remaining terms to maturity equally close to the Designated CMT Maturity Index, the quotes for the U.S. Treasury security with the shorter original term to maturity will be used.

●If fewer than three leading primary U.S. government securities reference dealers selected by the calculation agent provide quotes as described above, the CMT rate for the relevant interest reset date will be calculated using the Calculation Agent Alternative Rate Determination.

Index Cessation Event or Administrator/Benchmark Event. If an Index Cessation Event or an Administrator/Benchmark Event occurs with respect to the CMT rate, then, from and including the Index Cessation Effective Date or the Administrator/Benchmark Event Date, as applicable, the Alternative Post-nominated Index will apply to the CMT rate Notes. However, if by 5:00 p.m., New York City time, on the Cut-off Date, more than one Relevant Nominating Body formally designates, nominates or recommends an Alternative Post-nominated Index and those designations, nominations or recommendations are not the same, then the Calculation Agent Nominated Replacement Index will apply to the CMT rate notes.

In the event of a replacement of the CMT rate by either the Alternative Post-nominated Index or the Calculation Agent Nominated Replacement Index, the calculation agent shall (i) apply the Adjustment Spread (if applicable) to the Alternative Post-nominated Index or the Calculation Agent Nominated Replacement Index, as applicable, and (ii) after taking into account such Adjustment Spread, make any other adjustments to the terms of the notes that are necessary to account for the effect on the notes of referencing the Alternative Post-nominated Index or the Calculation Agent Nominated Replacement Index, as applicable.

“Calculation Agent Alternative Rate Determination” means that the calculation agent, after consulting with us, shall determine a commercially reasonable alternative for the Applicable Benchmark, taking into account all available information that in good faith the calculation agent considers relevant including a rate implemented

S-43

by central counterparties and/or futures exchanges (if any), in each case with trading volumes in derivatives or futures referencing the Applicable Benchmark that the calculation agent considers sufficient for that rate to be a representative alternative rate.

“Designated CMT LSEG page” means the display on LSEG, or any successor service (“LSEG”), on the page designated in the relevant pricing supplement or any other page as may replace that page on that service for the purpose of displaying Treasury constant maturities as reported in H.15. If no page is specified in the relevant pricing supplement, the Designated CMT LSEG page will be FEDCMT, for the most recent week.

“Designated CMT Index Maturity” means the original period to maturity of the U.S. Treasury securities, which is either 1, 2, 3, 5, 7, 10, 20 or 30 years, specified in the relevant pricing supplement for which the CMT rate will be calculated. If no maturity is specified in the relevant pricing supplement, the Designated CMT Index Maturity will be two years.

CPI Rate Notes

If you purchase a CPI rate note, your note will bear interest at an interest rate equal to the CPI rate and adjusted by the spread or spread multiplier, if any, indicated in the relevant pricing supplement.

Except as otherwise specified in the relevant pricing supplement, the CPI rate will be the rate, determined as of the relevant interest determination date, expressed as a percentage and calculated in accordance with the following formula:

● “C” means the CPI (as defined below) applicable for the calendar month which is one month preceding the month of the relevant interest determination date;

●“P” means the CPI applicable for the calendar month which is twelve months immediately preceding the calendar month for which C is determined; and

●“CPI” means the non-seasonally adjusted U.S. City Average All Items Consumer Price Index for All Urban Consumers, published monthly by the Bureau of Labor Statistics of the U.S. Department of Labor. For reference purposes only, the CPI is available on Bloomberg page CPURNSA or any successor service. In the event of an inconsistency between the CPI published on Bloomberg page CPURNSA and the CPI published by the Bureau of Labor Statistics, the CPI shall be the CPI published by the Bureau of Labor Statistics.

Federal Funds Rate Notes

If you purchase a federal funds rate note, your note will bear interest at an interest rate equal to the federal funds rate and adjusted by the spread or spread multiplier, if any, indicated in the relevant pricing supplement.

The federal funds rate will be the rate for U.S. dollar federal funds, as published in H.15 by 4:15 P.M., New York City time, on the relevant interest determination date, under the heading “Federal Funds (Effective)”, as that rate is displayed on the LSEG page FEDFUNDS1 under the heading “EFFECT”. If the federal funds rate cannot be determined in this manner, the following procedures will apply, unless specified otherwise in the relevant pricing supplement:

Temporary Non-Publication of the Federal Funds (Effective) Rate. Subject to the provisions below, if the federal funds (effective) rate is not so published by the later of (i) 4:15 p.m., New York City time, on the relevant interest reset date and (ii) the next Business day, then the rate for that interest determination date will be last provided or published level of the federal funds (effective) rate.

Index Cessation Event or Administrator/Benchmark Event. If an Index Cessation Event or an Administrator/Benchmark Event occurs with respect to the federal funds (effective) rate, then, from and including the Index Cessation Effective Date or the Administrator/Benchmark Event Date, as applicable, the Alternative Post-nominated Index will apply to the federal funds (effective) rate notes. However, if by 5:00 p.m., New York City time, on the Cut-off Date, more than one Relevant Nominating Body formally designates, nominates or recommends an Alternative Post-nominated Index and those designations, nominations or recommendations are not the same, then the Calculation Agent Nominated Replacement Index will apply to the federal funds (effective) rate notes.

S-44

In the event of a replacement of the federal funds rate by either the Alternative Post-nominated Index or the Calculation Agent Nominated Replacement Index, the calculation agent shall (i) apply the Adjustment Spread (if applicable) to the Alternative Post-nominated Index or the Calculation Agent Nominated Replacement Index, as applicable, and (ii) after taking into account such Adjustment Spread, make any other adjustments to the terms of the notes that are necessary to account for the effect on the notes of referencing the Alternative Post-nominated Index or the Calculation Agent Nominated Replacement Index, as applicable.

Special Rate Calculation Terms

In this subsection entitled “—Interest Rates”, we use several terms that have special meanings relevant to calculating floating interest rates. We define these terms as follows:

The term “business day” means, for any note, a day that meets all of the following applicable requirements:

●for all notes (except SOFR notes), is a Monday, Tuesday, Wednesday, Thursday or Friday that is neither a legal holiday nor a day on which banking institutions are authorized or required by law or executive order to close in New York City or Toronto,

●if the note has a specified currency other than U.S. dollars or euros, is also a day on which banking institutions are not authorized or obligated by law, regulation or executive order to close in the applicable principal financial center;

●if the note is a EURIBOR note or has a specified currency of euros, is also a TARGET Settlement Day; and

●if the note is a SOFR note, is a U.S. Government Securities Business Day.

The term “TARGET Settlement Day” means any day on which the Trans-European Automated Real-Time Gross Settlement Express Transfer (TARGET2) System, or any successor system, is open for settlement of payments in euro.

“H.15” means “Selected Interest Rates (Daily) – H.15”, or any successor publication as published daily by the Board of Governors of the Federal Reserve System at https://www.federalreserve.gov/releases/h15/, or any successor site or publication. We make no representation or warranty as to the accuracy or completeness of the information displayed on that website, and that information is not incorporated by reference herein and should not be considered a part of this prospectus supplement.

The term “index maturity” means, with respect to a floating rate note, the period to maturity of the instrument or obligation on which the interest rate formula is based, as specified in the relevant pricing supplement.

The term “principal financial center” means the capital city of the country to which an index currency relates (or the capital city of the country issuing the specified currency, as applicable), except that with respect to U.S. dollars, Australian dollars, Canadian dollars, South African rands and Swiss francs, the “principal financial center” means New York City, Sydney, Toronto, Johannesburg and Zurich, respectively, and with respect to euros the principal financial center means London.

The term “LSEG page” means the display on the LSEG Workspace, or any successor or replacement service, on the page or pages specified in this prospectus supplement or the relevant pricing supplement, or any successor or replacement page or pages on that service.

The term “LSEG page EURIBOR01” means the display on the LSEG screen page titled “EURIBOR01” on which EURIBOR rates of major banks for the euro are displayed.

The term “LSEG page FEDFUNDS1” means the display on the LSEG screen page titled “FEDFUNDS1” on which U.S. dollar federal funds rates are displayed.

The term “LSEG page USAUCTION10 or USAUCTION11” means the display on the LSEG screen page titled “USAUCTION10 or USAUCTION11” on which U.S. Treasury auction rates are displayed.

The term “Representative Amount” means an amount that, in the calculation agent’s judgment, is representative of a single transaction in the relevant market at the relevant time.

S-45

The term “U.S. Government Securities Business Day” means any day except for a Saturday, a Sunday or a day on which the Securities Industry and Financial Markets Association recommends that the fixed income departments of its members be closed for the entire day for purposes of trading in U.S. government securities.

If, when we use the terms H.15, LSEG page EURIBOR01, LSEG page FEDFUNDS1, or LSEG page USAUCTION10 or USAUCTION11, or we refer to a particular heading or headings on any of those pages, those references include any successor or replacement heading or headings as determined by the calculation agent.

Decisions and Determinations

Any determination, decision or election that may be made by the calculation agent or us pursuant to the benchmark replacement provisions described in this subsection entitled “Interest Rates,” including any determination with respect to tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection:

●will be conclusive and binding absent manifest error, may be made in the calculation agent’s sole discretion, and, notwithstanding anything to the contrary in this prospectus supplement, the accompanying prospectus or any other supplements relating to the notes;

●if made by us, will be made in our sole discretion;

●if made by the calculation agent, will be made after consultation with us, and the calculation agent will not make any such determination, decision or election to which we object; and

●shall become effective without consent from any other party.

Any determination, decision or election pursuant to the benchmark replacement provisions not made by the calculation agent will be made by us on the basis as described above. The calculation agent shall have no liability for not making any such determination, decision or election. In addition, we may designate an entity (the “Designee”, which may be our affiliate) to make any determination, decision or election that we have the right to make in connection with the benchmark replacement provisions set forth in this prospectus supplement.

Exchange Rate Agent. If we issue a note in a specified currency other than U.S. dollars, we will appoint a financial institution to act as the exchange rate agent and will name the institution initially appointed when the note is originally issued in the relevant pricing supplement. We may select CIBCWM or another of our affiliates to perform this role. We may change the exchange rate agent from time to time after the original issue date of the note without your consent and without notifying you of the change.

All determinations made by the exchange rate agent will be at its sole discretion unless we state in the relevant pricing supplement that any determination requires our approval. In the absence of manifest error, those determinations will be conclusive for all purposes and binding on you and us, without any liability on the part of the exchange rate agent.

Payment When Offices or Settlement Systems Are Closed

If any payment is due on the notes on a day that would otherwise be a business day but is a day on which the office of a paying agent or a settlement system is closed, we will make the payment on the next business day when that paying agent or system is open.  Any such payment will be deemed to have been made on the original due date, and no additional interest will be paid on account of the delay.

Withholding

The Bank or the applicable paying agent will deduct or withhold from a payment on a note any present or future tax, duty, assessment or other governmental charge that the Bank determines is required by law or the interpretation or administration thereof to be deducted or withheld. Payments on a note will not be increased by any amount to offset such deduction or withholding, unless otherwise specified in the relevant pricing supplement.

Special Provisions Related to Bail-inable Notes

The indenture provides for certain provisions applicable to bail-inable notes. The relevant pricing supplement will specify whether or not your note is a bail-inable note.

S-46

Agreement with Respect to the Exercise of Canadian Bail-in Powers

By its acquisition of an interest in any bail-inable note, each holder or beneficial owner of that note is deemed to (i) agree to be bound, in respect of the bail-inable notes, by the CDIC Act, including the conversion of the bail-inable notes, in whole or in part – by means of a transaction or series of transactions and in one or more steps – into common shares of the Bank or any of its affiliates under subsection 39.2(2.3) of the CDIC Act and the variation or extinguishment of the bail-inable notes in consequence, and by the application of the laws of the Province of Ontario and the federal laws of Canada applicable therein in respect of the operation of the CDIC Act with respect to the bail-inable notes; (ii) attorn and submit to the jurisdiction of the courts in the Province of Ontario with respect to the CDIC Act and those laws; and (iii) acknowledge and agree that the terms referred to in clauses (i) and (ii) above, are binding on that holder or beneficial owner despite any provisions in the indenture or the bail-inable notes, any other law that governs the bail-inable notes and any other agreement, arrangement or understanding between that holder or beneficial owner and the Bank with respect to the bail-inable notes.

Holders and beneficial owners of bail-inable notes will have no further rights in respect of their bail-inable notes to the extent those bail-inable notes are converted in a bail-in conversion, other than those provided under the bail-in regime, and by its acquisition of an interest in any bail-inable note, each holder or beneficial owner of that note is deemed to irrevocably consent to the principal amount of that note and any accrued and unpaid interest thereon being deemed paid in full by the Bank by the issuance of common shares of the Bank (or, if applicable, any of its affiliates) upon the occurrence of a bail-in conversion, which bail-in conversion will occur without any further action on the part of that holder or beneficial owner or the trustee; provided that, for the avoidance of doubt, this consent will not limit or otherwise affect any rights that holders or beneficial owners may have under the bail-in regime.

TLAC Disqualification Event Redemption

If a TLAC Disqualification Event is specified in the relevant pricing supplement, we may, at our option, with the prior approval of the Superintendent, redeem all but not less than all of the particular bail-inable notes prior to their stated maturity date after the occurrence of the TLAC Disqualification Event at the time or times and at the redemption price or prices specified in that pricing supplement, together with unpaid interest accrued thereon to, but excluding, the date fixed for redemption.

A “TLAC Disqualification Event” means that the Superintendent has advised the Bank in writing that the bail-inable notes issued under the relevant pricing supplement will no longer be recognized in full as TLAC under the TLAC Guideline as interpreted by the Superintendent, provided that a TLAC Disqualification Event will not occur where the exclusion of those bail-inable notes from the Bank’s TLAC requirements is due to the remaining maturity of those bail-inable notes being less than any period prescribed by any relevant eligibility criteria applicable as of the issue date of those bail-inable notes.

No Set-Off or Netting Rights

Holders and beneficial owners of bail-inable notes will not be entitled to exercise, or direct the exercise of, any set-off or netting rights with respect to their bail-inable notes.

Approval of Redemption, Repurchases and Defeasance; Amendments and Modifications

Where the redemption, repurchase or any defeasance or covenant defeasance with respect to bail-inable notes would result in the Bank not meeting the TLAC requirements applicable to it pursuant to the TLAC Guideline, that redemption, repurchase, defeasance or covenant defeasance will be subject to the prior approval of the Superintendent.

Where an amendment, modification or other variance that can be made to the indenture or the bail-inable notes as described in the accompanying prospectus under “Description of Senior Debt Securities — Modification and Waiver of the Senior Debt Securities” would affect the recognition of those bail-inable notes by the Superintendent as TLAC, that amendment, modification or variance will require the prior approval of the Superintendent.

Remedies If an Event of Default Occurs

Holders and beneficial owners of bail-inable notes may only exercise, or direct the exercise of, the rights described in the accompanying prospectus under “Description of Senior Debt Securities — Events of Default — Remedies If an Event of Default Occurs” if the Governor in Council (Canada) has not made an Order under

S-47

Canadian bank resolution powers pursuant to subsection 39.13(1) of the CDIC Act in respect of the Bank. Notwithstanding the exercise of those rights, bail-inable notes will continue to be subject to bail-in conversion until repaid in full.

Subsequent Holders’ Agreement

Each holder or beneficial owner of a bail-inable note that acquires an interest in the bail-inable note in the secondary market and any successors, assigns, heirs, executors, administrators, trustees in bankruptcy and legal representatives of any holder or beneficial owner is deemed to acknowledge, accept, agree to be bound by and consent to the same provisions specified herein to the same extent as the holders or beneficial owners that acquired an interest in the bail-inable notes upon their initial issuance, including, without limitation, with respect to the acknowledgement and agreement to be bound by and consent to the terms of the bail-inable notes related to the bail-in regime.

Governing Law; Submission to Jurisdiction

The indenture and the notes are governed by and construed in accordance with the laws of the State of New York, except that the provisions relating to the bail-in acknowledgment of holders and beneficial owners of bail-inable notes described in the first paragraph under “— Agreement with Respect to the Exercise of Canadian Bail-in Powers” above, are governed by and construed in accordance with the laws of the Province of Ontario and the federal laws of Canada applicable therein. By its acquisition of an interest in any bail-inable note, each holder or beneficial owner of that bail-inable note is deemed to attorn and submit to the jurisdiction of the courts in the Province of Ontario with respect to actions, suits and proceedings arising out of or relating to the operation of the CDIC Act and the laws of the Province of Ontario and the federal laws of Canada applicable therein in respect of the indenture and the bail-inable note.

Other Provisions; Addenda

Any provisions relating to the notes, including the determination of the interest rate basis, calculation of the interest rate applicable to a floating rate note, its interest payment dates, any redemption or repayment provisions, or any other term relating thereto, may be modified and/or supplemented by the terms on the face of the applicable notes or in an addendum relating to the applicable notes, if so specified on the face of the applicable notes, and, in each case, in the relevant pricing supplement.

S-48

SUPPLEMENTAL PLAN OF DISTRIBUTION (CONFLICTS OF INTEREST)

We and CIBCWM, as agent, have entered into a distribution agreement with respect to the notes. We may appoint agents, other than or in addition to CIBCWM, with respect to the notes. Any other agent has entered or will enter into a distribution agreement with us. The other agents may be affiliates or customers of the Bank and may engage in transactions with and perform services for the Bank in the ordinary course of business. CIBCWM may resell notes to or through another selling agent, which may include another of our affiliates. The agent or agents through whom the notes will be offered will be identified in the relevant pricing supplement.

Subject to certain conditions, an agent will use its reasonable efforts to solicit purchases of the notes. We have the right to accept offers to purchase notes and may reject any proposed purchase of the notes. An agent may also reject any offer to purchase notes. We will pay an agent a commission, which will be in such amount as may be agreed between the agent and the Bank and will be set forth in the relevant pricing supplement, on any notes sold through such agent.

We may also sell notes to an agent, who will purchase the notes as principal for its own account. In that case, the agent will purchase the notes at a price equal to the issue price specified in the relevant pricing supplement, less a discount to be agreed with us at the time of the offering.

An agent may resell any notes it purchases as principal to other brokers or dealers at a discount, which may include all or part of the discount the agent received from us. If all the notes are not sold at the initial offering price, the agent may change the offering price and the other selling terms.

We may also sell notes directly to investors. We will not pay commissions on notes we sell directly.

We have reserved the right to withdraw, cancel or modify the offer made by this prospectus supplement without notice and may reject orders in whole or in part, whether placed directly with us or with an agent. No termination date has been established for the offering of the notes.

An agent, whether acting as agent or principal, may be deemed to be an “underwriter” within the meaning of the U.S. Securities Act of 1933, as amended (the “Securities Act”). We have agreed to indemnify the agents against certain liabilities, including liabilities under the Securities Act, or to contribute to payments made in respect of those liabilities.

If an agent sells notes to dealers who resell to investors and the agent pays the dealers all or part of the discount or commission it receives from us, those dealers may also be deemed to be “underwriters” within the meaning of the Securities Act.

Unless otherwise indicated in any pricing supplement, payment of the purchase price of notes, other than notes denominated in a non-U.S. dollar currency, will be required to be made in funds immediately available in The City of New York. The notes will be in the Same Day Funds Settlement System at DTC and, to the extent the secondary market trading in the notes is effected through the facilities of such depositary, such trades will be settled in immediately available funds.

Delivery of the notes will be made against payment therefor in New York, New York, on a date that is more than one business day following the trade date. Under Rule 15c6-1 of the Exchange Act, 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 on any date prior to one business day before delivery will be required to specify alternative settlement arrangements to prevent a failed settlement.

The notes are a new issue of securities, and there will be no established trading market for any note before its original issue date. We do not plan to list the notes on a securities exchange or quotation system. An agent may make a market in the notes offered through it. However, neither CIBCWM nor any of our other affiliates nor any other agent named in the relevant pricing supplement that makes a market is obligated to do so, and its ability to make a market in the notes may be impacted by changes in any regulatory requirements applicable to the marketing, holding and trading of, and issuing quotations with respect to, the notes. Any of them may stop doing so at any time without notice. No assurance can be given as to the liquidity or trading market for the notes.

This prospectus supplement may be used by CIBCWM or any other agent in connection with offers and sales of the notes in market-making transactions. In a market-making transaction, an agent or other person may resell a note it acquires from other holders after the original offering and sale of the note. Resales of this kind may occur in the open market or may be privately negotiated, at prevailing market prices at the time of resale or at related

S-49

or negotiated prices. In these transactions, such agent may act as principal or agent, including as agent for the counterparty in a transaction in which CIBCWM or another agent acts as principal, or as agent for both counterparties in a transaction in which CIBCWM does not act as principal. The agents may receive compensation in the form of discounts and commissions, including from both counterparties in some cases. Other affiliates of the Bank (in addition to CIBCWM) may also engage in transactions of this kind and may use this prospectus supplement for this purpose.

Unless the Bank or an agent informs you in your confirmation of sale that your note is being purchased in its original offering and sale, you may assume that you are purchasing your note in a market-making transaction.

The aggregate initial offering price specified on the cover of this prospectus supplement relates to the initial offering of new notes we may issue on and after the date of this prospectus supplement. This amount does not include notes that may be resold in market-making transactions. The latter includes notes that we may issue going forward as well as notes we have previously issued.

The Bank does not expect to receive any proceeds from market-making transactions other than those it undertakes on its own. The Bank does not expect that any agent that engages in these transactions will pay any proceeds from its market-making resales to the Bank.

Information about the trade and settlement dates, as well as the purchase price, for a market-making transaction will be provided to the purchaser in a separate confirmation of sale.

In this prospectus supplement, the term “this offering” means the initial offering of the notes made in connection with their original issuance. This term does not refer to any subsequent resales of notes in market-making transactions.

An agent may engage in over-allotment, stabilizing transactions, syndicate covering transactions and penalty bids in accordance with Regulation M under the Exchange Act. Over-allotment involves syndicate sales in excess of the offering size, which creates a syndicate short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. Syndicate covering transactions involve purchases of the notes in the open market after the distribution has been completed in order to cover syndicate short positions. Penalty bids permit reclaiming a selling concession from a syndicate member when the notes originally sold by such syndicate member are purchased in a syndicate covering transaction to cover syndicate short positions. Such stabilizing transactions, syndicate covering transactions and penalty bids may stabilize, maintain or otherwise affect the market price of the notes, which may be higher than it would otherwise be in the absence of such transactions. Agents are not required to engage in these activities, and may end any of these activities at any time.

In addition to offering notes through the agents as discussed above, other medium-term notes that have terms substantially similar to the terms of the notes offered by this prospectus supplement may in the future be offered, concurrently with the offering of the notes, on a continuing basis by the Bank. Any of these notes sold pursuant to the distribution agreement or sold by the Bank directly to investors will reduce the aggregate amount of notes which may be offered by this prospectus supplement.

Conflicts of Interest

Because CIBCWM is an affiliate of the Bank, CIBCWM has a “conflict of interest” as defined in Rule 5121 of the U.S. Financial Industry Regulatory Authority, Inc. (“Rule 5121”). In addition, the Bank will receive the net proceeds from an initial public offering of the notes, thus creating an additional conflict of interest within the meaning of Rule 5121. Consequently, any such offering is being conducted in compliance with the provisions of Rule 5121. Neither CIBCWM nor any other agent is permitted to sell notes in any such offering to an account over which it exercises discretionary authority without the prior specific written approval of the account holder.
