SUMMARY

The information in this “Summary” section is qualified by the more detailed information set forth in the underlying supplement, the prospectus supplement and the prospectus. See “Additional Terms of the Notes” in this pricing supplement.

HYPOTHETICAL PAYMENT AT MATURITY

The following table and examples are provided for illustrative purposes only and are hypothetical. They do not purport to be representative of every possible scenario concerning increases or decreases in the Final Level of any Underlying relative to its Initial Level. We cannot predict the Closing Level of any Underlying on any Call Observation Date, including the Final Valuation Date. The assumptions we have made in connection with the illustrations set forth below may not reflect actual events. You should not take this illustration or these examples as an indication or assurance of the expected performance of the Underlyings or return on the notes. The numbers appearing in the table below and following examples have been rounded for ease of analysis.

The table below illustrates the Payment at Maturity on a $1,000 investment in the notes for a hypothetical range of Percentage Changes of the Worst Performing Underlying from -100% to +100%. The following results are based solely on the assumptions outlined below. The “Hypothetical Return on the Notes” as used below is the number, expressed as a percentage, that results from comparing the Payment at Maturity per $1,000 principal amount to $1,000. The potential returns described below assume that the notes have not been automatically called prior to maturity and are held to maturity. The following table and examples are based on the following terms:

The following examples indicate how the Payment at Maturity would be calculated with respect to a hypothetical $1,000 investment in the notes assuming that the notes have not been automatically called prior to maturity and are held to maturity.

Example 1: The Percentage Change of the Worst Performing Underlying Is 75.00%.

Because the Final Level of the Worst Performing Underlying is greater than or equal to its applicable Call Level, the Payment at Maturity would be $1,530.00 per $1,000 principal amount, calculated as follows:

$1,000 + applicable Call Premium

= $1,000 + $530.00

= $1,530.00

Example 1 shows that the Payment at Maturity will be fixed at the principal amount plus the applicable Call Premium when the Final Level of the Worst Performing Underlying is at or above its applicable Call Level, regardless of the extent to which the level of the Worst Performing Underlying increases.

Example 2: The Percentage Change of the Worst Performing Underlying Is -20.00%.

Because the Final Level of the Worst Performing Underlying is greater than or equal to its applicable Call Level, the Payment at Maturity would be $1,530.00 per $1,000 principal amount, calculated as follows:

$1,000 + applicable Call Premium

= $1,000 + $530.00

= $1,530.00

Example 2 shows that the Payment at Maturity will be fixed at the principal amount plus the applicable Call Premium when the Final Level of the Worst Performing Underlying is at or above its applicable Call Level, although its level has decreased moderately.

Example 3: The Percentage Change of the Worst Performing Underlying Is -40.00%.

Because the Final Level of the Worst Performing Underlying is less than its applicable Call Level but greater than or equal to its Barrier Level, the Payment at Maturity would be $1,000.00 per $1,000 principal amount.

Example 3 shows that the Payment at Maturity will be the principal amount when the Final Level of the Worst Performing Underlying is below its applicable Call Level but at or above its Barrier Level, although the level of the Worst Performing Underlying has decreased moderately.

Example 4: The Percentage Change of the Worst Performing Underlying Is -75.00%.

Because the Final Level of the Worst Performing Underlying is less than its Barrier Level, the Payment at Maturity would be $250.00 per $1,000 principal amount, calculated as follows:

$1,000 + ($1,000 × Percentage Change of the Worst Performing Underlying)

= $1,000 + ($1,000 × -75.00%)

= $250.00

Example 4 shows that you are exposed on a 1-to-1 basis to any decrease in the level of the Worst Performing Underlying from its Initial Level if the notes are not called. You may lose up to 100% of your principal amount at maturity.

These examples illustrate that you will not participate in any appreciation of any Underlying, but will be fully exposed to a decrease in the Worst Performing Underlying if the notes are not called, and the Final Level of the Worst Performing Underlying is less than its Barrier Level, even if the Final Levels of the other Underlyings has appreciated or has not declined below its Barrier Level.

INVESTOR CONSIDERATIONS

The notes are not appropriate for all investors. The notes may be an appropriate investment for you if:

The notes may not be an appropriate investment for you if:

The investor suitability considerations identified above are not exhaustive. Whether or not the notes are a suitable investment for you will depend on your individual circumstances and you should reach an investment decision only after you and your investment, legal, tax, accounting and other advisors have carefully considered the suitability of an investment in the notes in light of your particular circumstances. You should also review ‘‘Additional Risk Factors’’ below for risks related to the notes.

ADDITIONAL RISK FACTORS

An investment in the notes involves significant risks. In addition to the following risks included in this pricing supplement, we urge you to read “Risk Factors” beginning on page S-1 of the accompanying underlying supplement, page S-1 of the prospectus supplement and page 1 of the prospectus.

You should understand the risks of investing in the notes and should reach an investment decision only after careful consideration, with your advisers, of the suitability of the notes in light of your particular financial circumstances and the information set forth in this pricing supplement and the accompanying underlying supplement, the prospectus supplement and the prospectus.

Structure Risks

If the notes are not called, you will lose a substantial portion or all of the principal amount of your notes.

The notes do not guarantee any return of principal. The repayment of any principal on the notes at maturity depends on the Final Level of the Worst Performing Underlying. If the notes are not called on any Call Observation Date, including the Final Valuation Date, and the Final Level of the Worst Performing Underlying is less than its Barrier Level, you will lose 1% of the principal amount for each percentage point that the Final Level of the Worst Performing Underlying is less than its Initial Level. You may lose a substantial portion or all of the principal amount.

The notes are subject to reinvestment risk.

Because of the automatic Call Feature, the term of your investment in the notes may be limited to a period that is shorter than the original term of the notes and may be as short as approximately one year. There is no guarantee that you would be able to reinvest the proceeds from an investment in the notes at a comparable return for a similar level of risk in the event the notes are automatically called prior to the Maturity Date.

You will not participate in any appreciation of any Underlying and your return on the notes will be limited to the applicable Call Premium, if payable.

The payment on the notes on any Call Payment Date, including the Maturity Date, will not exceed the principal amount plus the applicable Call Premium, and any positive return you receive on the notes will be limited to the applicable Call Premium. If the notes are called, you will not participate in any appreciation of any Underlying. Therefore, if the appreciation of any Underlying exceeds the applicable Call Premium, the notes will underperform an investment in securities linked to that Underlying providing full participation in the appreciation. Accordingly, the return on the notes may be less than the return would be if you made an investment in securities directly linked to the positive performance of the Underlyings.

The payment on the notes is not linked to the level of the Underlyings at any time other than the Call Observation Dates, including the Final Valuation Date.

The payment on the notes will be based on the Closing Level of each Underlying on the Call Observation Dates, including the Final Valuation Date. Therefore, if the Closing Level of an Underlying declined as of a Call Observation Date below its applicable Call Level, the notes will not be called and the relevant Call Premium will not be payable. Similarly, if the Final Level of the Worst Performing Underlying declined as of the Final Valuation Date below its Barrier Level, the Payment at Maturity may be significantly less than it would otherwise have been had the Payment at Maturity been linked to the Closing Level of the Worst Performing Underlying on a date other than the Final Valuation Date. Although the actual level of an Underlying at other times during the term of the notes may be higher than its Closing Level on a Call Observation Date, the payment on the notes will not benefit from the Closing Level of such Underlying at any time other than the Call Observation Dates, including the Final Valuation Date.

The notes do not pay interest.

You will not receive any interest payments on the notes. Even if the amount payable on the notes at maturity or upon an automatic call exceeds the principal amount of the notes, the overall return you earn on the notes may be less than you would otherwise have earned by investing in a non-indexed debt security of comparable maturity that bears interest at a prevailing market rate. Your investment may not reflect the full opportunity cost to you when you take into account factors that affect the time value of money.

The notes are riskier than notes with a shorter term.

The notes are relatively long-dated. Therefore, many of the risks of the notes are heightened as compared to notes with a shorter term, as you will be subject to those risks for a longer period of time. In addition, the value of a longer-dated note is typically less than the value of an otherwise comparable note with a shorter term.

Reference Asset Risks

The notes are subject to the full risks of the Worst Performing Underlying and will be negatively affected if any Underlying performs poorly, even if the other Underlying performs favorably.

You are subject to the full risks of the Worst Performing Underlying. If the Worst Performing Underlying performs poorly, you will be negatively affected, even if the other Underlying performs favorably. The notes are not linked to a basket composed of the Underlyings, where the better performance of some Underlyings could offset the poor performance of others. Instead, you are subject to the full risks of the Worst Performing Underlying on each Call Observation Date, including the Final Valuation Date. As a result, the notes are riskier than an alternative investment linked to only one of the Underlyings or linked to a basket composed of the Underlyings. You should not invest in the notes unless you understand and are willing to accept the full downside risks of the Worst Performing Underlying.

There are risks associated with investments in securities linked to the value of non-U.S. equity securities.

Some of the equity securities composing the NDX are issued by non-U.S. companies. Investments in securities linked to the value of such non-U.S. equity securities, such as the notes, involve risks associated with the home countries of the issuers of those non-U.S. equity securities. The prices of securities in non-U.S. markets may be affected by political, economic, financial and social factors in those countries or global regions, including changes in government, economic and fiscal policies and currency exchange laws.

Conflicts of Interest

Certain business, trading and hedging activities of us, the agent, and our other affiliates may create conflicts with your interests and could potentially adversely affect the value of the notes.

We, the agent, and our other affiliates may engage in trading and other business activities related to an Underlying or any securities included in that Underlying that are not for your account or on your behalf. We, the agent, and our other affiliates also may issue or underwrite other financial instruments with returns based upon an Underlying. These activities may present a conflict of interest between your interest in the notes and the interests that we, the agent, and our other affiliates may have in our or their proprietary accounts, in facilitating transactions, including block trades, for our or their other customers, and in accounts under our or their management. These trading and other business activities, if they adversely affect the level of any Underlying or secondary trading in your notes, could be adverse to your interests as a beneficial owner of the notes.

Moreover, we, the agent and our other affiliates play a variety of roles in connection with the issuance of the notes, including hedging our obligations under the notes and making the assumptions and inputs used to determine the pricing of the notes and the initial estimated value of the notes when the terms of the notes are set. We expect to hedge our obligations under the notes through the agent, one of our other affiliates, and/or another unaffiliated counterparty, which may include any dealer from which you purchase the notes. Any of these hedging activities may adversely affect the level of an Underlying and therefore the market value of the notes and the amount you will receive, if any, on the notes. In connection with such activities, the economic interests of us, the agent, and our other affiliates may be adverse to your interests as an investor in the notes. Any of these activities may adversely affect the value of the notes. In addition, because hedging our obligations entails risk and may be influenced by market forces beyond our control, this hedging activity may result in a profit that is more or less than expected, or it may result in a loss. We, the agent, one or more of our other affiliates or any unaffiliated counterparty will retain any profits realized in hedging our obligations under the notes even if investors do not receive a favorable investment return under the terms of the notes or in any secondary market transaction. Any profit in connection with such hedging activities will be in addition to any other compensation that we, the agent, our other affiliates or any unaffiliated counterparty receive for the sale of the notes, which creates an additional incentive to sell the notes to you. We, the agent, our other affiliates or any unaffiliated counterparty will have no obligation to take, refrain from taking or cease taking any action with respect to these transactions based on the potential effect on an investor in the notes.

There are potential conflicts of interest between you and the calculation agent.

The calculation agent will determine, among other things, the amount of payment on the notes. The calculation agent will exercise its judgment when performing its functions. For example, the calculation agent will determine whether a Market Disruption Event affecting an Underlying has occurred, and determine the Closing Level for an affected Underlying if a scheduled Call Observation Date is postponed to the last possible day. See “Certain Terms of the Notes—Valuation Dates—For Notes Where the Reference Asset Consists of Multiple Indices” in the underlying supplement. This determination may, in turn, depend on the calculation agent’s judgment as to whether the event has materially interfered with our ability or the ability of one of our affiliates to unwind our hedge positions. The calculation agent will be required to carry out its duties in good faith and use its reasonable judgment. However, because we will be the calculation agent, potential conflicts of interest could arise. None of us, CIBCWM or any of our other affiliates will have any obligation to consider your interests as a holder of the notes in taking any action that might affect the value of your notes.

Tax Risks

The tax treatment of the notes is uncertain.

Significant aspects of the tax treatment of the notes are uncertain. You should consult your tax advisor about your own tax situation. See “United States Federal Income Tax Considerations” and “Certain Canadian Federal Income Tax Considerations” in this pricing supplement, “Material U.S. Federal Income Tax Consequences” in the underlying supplement and “Material Income Tax Consequences – Canadian Taxation” in the prospectus.

General Risks

Payment on the notes is subject to our credit risk, and actual or perceived changes in our creditworthiness are expected to affect the value of the notes.

The notes are our senior unsecured debt obligations and are not, either directly or indirectly, an obligation of any third party. As further described in the accompanying prospectus and prospectus supplement, the notes will rank on par with all of our other unsecured and unsubordinated debt obligations, except such obligations as may be preferred by operation of law. Any payment to be made on the notes depends on our ability to satisfy our obligations as they come due. As a result, the actual and perceived creditworthiness of us may affect the market value of the notes and, in the event we were to default on our obligations, you may not receive the amounts owed to you under the terms of the notes. If we default on our obligations under the notes, your investment would be at risk and you could lose some or all of your investment. See “Description of Senior Debt Securities—Events of Default” in the accompanying prospectus.

The Bank’s initial estimated value of the notes is lower than the initial issue price (price to public) of the notes.

The initial issue price of the notes exceeds the Bank’s initial estimated value because costs associated with selling and structuring the notes, as well as hedging the notes, are included in the initial issue price of the notes. See “The Bank’s Estimated Value of the Notes” in this pricing supplement.

The Bank’s initial estimated value does not represent future values of the notes and may differ from others’ estimates.

The Bank’s initial estimated value of the notes is only an estimate, which was determined by reference to the Bank’s internal pricing models when the terms of the notes were set. This estimated value was based on market conditions and other relevant factors existing at that time, the Bank’s internal funding rate on the Trade Date and the Bank’s assumptions about market parameters, which can include volatility, dividend rates, interest rates and other factors. Different pricing models and assumptions could provide valuations for the notes that are greater or less than the Bank’s initial estimated value. In addition, market conditions and other relevant factors in the future may change, and any assumptions may prove to be incorrect. On future dates, the market value of the notes could change significantly based on, among other things, changes in market conditions, including the level of each Underlying, the Bank’s creditworthiness, interest rate movements and other relevant factors, which may impact the price at which the agent or any other party would be willing to buy the notes from you in any secondary market transactions. The Bank’s initial estimated value does not represent a minimum price at which the agent or any other party would be willing to buy the notes in any secondary market (if any exists) at any time. See “The Bank’s Estimated Value of the Notes” in this pricing supplement.

The Bank’s initial estimated value of the notes was not determined by reference to credit spreads for our conventional fixed-rate debt. The internal funding rate used in the determination of the Bank’s initial estimated value of the notes generally represents a discount from the credit spreads for our conventional fixed-rate debt. The discount is based on, among other things, our view of the funding value of the notes as well as the higher issuance, operational and ongoing liability management costs of the notes in comparison to those costs for our conventional fixed-rate debt. If the Bank were to have used the interest rate implied by our conventional fixed-rate debt, we would expect the economic terms of the notes to be more favorable to you. Consequently, our use of an internal funding rate for market-linked notes had an adverse effect on the economic terms of the notes and the initial estimated value of the notes on the Trade Date, and could have an adverse effect on any secondary market prices of the notes. See “The Bank’s Estimated Value of the Notes” in this pricing supplement.

The notes will not be listed on any securities exchange and we do not expect a trading market for the notes to develop.

The notes will not be listed on any securities exchange. Although CIBCWM and/or its affiliates may purchase the notes from holders, they are not obligated to do so and are not required to make a market for the notes. There can be no assurance that a secondary market will develop for the notes. Because we do not expect that any market makers will participate in a secondary market for the notes, the price at which you may be able to sell your notes is likely to depend on the price, if any, at which CIBCWM and/or its affiliates are willing to buy your notes.

If a secondary market does exist, it may be limited. Accordingly, there may be a limited number of buyers if you decide to sell your notes prior to maturity or automatic call. This may affect the price you receive upon such sale. Consequently, you should be willing to hold the notes to maturity or automatic call.

UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following discussion is a brief summary of the material U.S. federal income tax considerations relating to an investment in the notes. The following summary is not complete and is both qualified and supplemented by (although to the extent inconsistent supersedes) the discussion entitled “Material U.S. Federal Income Tax Consequences” in the underlying supplement, which you should carefully review prior to investing in the notes. It applies only to those U.S. Holders who are not excluded from the discussion of United States Taxation in the accompanying prospectus.

The U.S. federal income tax considerations of your investment in the notes are uncertain. No statutory, judicial or administrative authority directly discusses how the notes should be treated for U.S. federal income tax purposes. In the opinion of our tax counsel, Mayer Brown LLP, it would generally be reasonable to treat the notes as prepaid derivative contracts. Pursuant to the terms of the notes, you agree to treat the notes in this manner for all U.S. federal income tax purposes. If this treatment is respected, you should generally recognize capital gain or loss upon the sale, exchange, cash redemption or payment upon maturity in an amount equal to the difference between the amount you receive in such transaction and the amount that you paid for your notes. Such gain or loss should generally be treated as long-term capital gain or loss if you have held your notes for more than one year.

The expected characterization of the notes is not binding on the U.S. Internal Revenue Service (the “IRS”) or the courts. It is possible that the IRS would seek to characterize the notes in a manner that results in tax consequences to you that are different from those described above or in the accompanying underlying supplement. Such alternate treatments could include a requirement that a holder accrue ordinary income over the life of the notes or treat all gain or loss at maturity as ordinary gain or loss. For a more detailed discussion of certain alternative characterizations with respect to the notes and certain other considerations with respect to an investment in the notes, you should consider the discussion set forth in “Material U.S. Federal Income Tax Consequences” of the underlying supplement. We are not responsible for any adverse consequences that you may experience as a result of any alternative characterization of the notes for U.S. federal income tax or other tax purposes.

You should consult your tax advisor as to the tax consequences of such characterization and any possible alternative characterizations of the notes for U.S. federal income tax purposes. You should also consult your tax advisor concerning the U.S. federal income tax and other tax consequences of your investment in the notes in your particular circumstances, including the application of state, local or other tax laws and the possible effects of changes in federal or other tax laws.

CERTAIN CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

In the opinion of Blake, Cassels & Graydon LLP, our Canadian tax counsel, the following summary describes the principal Canadian federal income tax considerations under the Income Tax Act (Canada) and the regulations thereto (the “Canadian Tax Act”) generally applicable at the date hereof to a purchaser who acquires beneficial ownership of a note pursuant to this pricing supplement and who for the purposes of the Canadian Tax Act and at all relevant times: (a) is neither resident nor deemed to be resident in Canada; (b) deals at arm’s length with the Issuer and any transferee resident (or deemed to be resident) in Canada to whom the purchaser disposes of the note; (c) does not use or hold and is not deemed to use or hold the note in, or in the course of, carrying on a business in Canada; (d) is entitled to receive all payments (including any interest and principal) made on the note; (e) is not a, and deals at arm’s length with any, “specified shareholder” of the Issuer for purposes of the thin capitalization rules in the Canadian Tax Act; and (f) is not an entity in respect of which the Issuer or any transferee resident (or deemed to be resident) in Canada to whom the purchaser disposes of, loans or otherwise transfers the note is a “specified entity”, and is not a “specified entity” in respect of such a transferee, in each case, for purposes of the Hybrid Mismatch Proposals, as defined below (a “Non-Resident Holder”). Special rules which apply to non-resident insurers carrying on business in Canada and elsewhere are not discussed in this summary.

This summary assumes that no amount paid or payable to a holder described herein will be the deduction component of a “hybrid mismatch arrangement” under which the payment arises within the meaning of proposed paragraph 18.4(3)(b) of the Canadian Tax Act contained in the proposals to amend the Canadian Tax Act released by the Minister of Finance (Canada) on April 29, 2022 with respect to “hybrid mismatch arrangements” (the “Hybrid Mismatch Proposals”). Investors should note that the Hybrid Mismatch Proposals are in consultation form, are highly complex, and there remains significant uncertainty as to their interpretation and application. There can be no assurance that the Hybrid Mismatch Proposals will be enacted in their current form, or at all.

This summary is supplemental to and should be read together with the description of material Canadian federal income tax considerations relevant to a Non-Resident Holder owning notes under “Material Income Tax Consequences—Canadian Taxation” in the accompanying prospectus and a Non-Resident Holder should carefully read that description as well.

This summary is of a general nature only and is not intended to be, nor should it be construed to be, legal or tax advice to any particular Non-Resident Holder. Non-Resident Holders are advised to consult with their own tax advisors with respect to their particular circumstances.

Based on Canadian tax counsel’s understanding of the Canada Revenue Agency’s administrative policies and having regard to the terms of the notes, interest payable on the notes should not be considered to be “participating debt interest” as defined in the Canadian Tax Act and accordingly, a Non-Resident Holder should not be subject to Canadian non-resident withholding tax in respect of amounts paid or credited or deemed to have been paid or credited by the Issuer on a note as, on account of or in lieu of payment of, or in satisfaction of, interest.

Non-Resident Holders should consult their own advisors regarding the consequences to them of a disposition of the notes to a person with whom they are not dealing at arm’s length for purposes of the Canadian Tax Act.

SUPPLEMENTAL PLAN OF DISTRIBUTION (CONFLICTS OF INTEREST)

CIBCWM will purchase the notes from CIBC at the price to public less the underwriting discount set forth on the cover page of this pricing supplement for distribution to other registered broker-dealers, or will offer the notes directly to investors. CIBCWM or other registered broker-dealers will offer the notes at the price to public set forth on the cover page of this pricing supplement. CIBCWM may receive a commission of $3.00 (0.30%) per $1,000 principal amount of the notes and may use a portion or all of that commission to allow selling concessions to other dealers in connection with the distribution of the notes. The other dealers may forgo, in their sole discretion, some or all of their selling concessions. The price to public for notes purchased by certain fee-based advisory accounts will be 99.70% of the principal amount of the notes. Any sale of a note to a fee-based advisory account at a price to public below 100.00% of the principal amount will reduce the agent’s commission specified on the cover page of this pricing supplement with respect to such note. The price to public paid by any fee-based advisory account will be reduced by the amount of any fees assessed by the dealers involved in the sale of the notes to such advisory account but not by more than 0.30% of the principal amount of the notes.

CIBCWM is our affiliate, and is deemed to have a conflict of interest under FINRA Rule 5121. In accordance with FINRA Rule 5121, CIBCWM may not make sales in this offering to any of its discretionary accounts without the prior written approval of the customer.

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

The Bank may use this pricing supplement in the initial sale of the notes. In addition, CIBCWM or another of the Bank’s affiliates may use this pricing supplement in market-making transactions in any notes after their initial sale. Unless CIBCWM or we inform you otherwise in the confirmation of sale, this pricing supplement is being used by CIBCWM in a market-making transaction.

While CIBCWM may make markets in the notes, it is under no obligation to do so and may discontinue any market-making activities at any time without notice. The price that it makes available from time to time after the Original Issue Date at which it would be willing to repurchase the notes will generally reflect its estimate of their value. That estimated value will be based upon a variety of factors, including then prevailing market conditions, our creditworthiness and transaction costs. However, for a period of approximately three months after the Trade Date, the price at which CIBCWM may repurchase the notes is expected to be higher than their estimated value at that time. This is because, at the beginning of this period, that price will not include certain costs that were included in the initial issue price, particularly our hedging costs and profits. As the period continues, these costs are expected to be gradually included in the price that CIBCWM would be willing to pay, and the difference between that price and CIBCWM’s estimate of the value of the notes will decrease over time until the end of this period. After this period, if CIBCWM continues to make a market in the notes, the prices that it would pay for them are expected to reflect its estimated value, as well as customary bid-ask spreads for similar trades. In addition, the value of the notes shown on your account statement may not be identical to the price at which CIBCWM would be willing to purchase the notes at that time, and could be lower than CIBCWM’s price. See the section titled “Supplemental Plan of Distribution (Conflicts of Interest)” in the accompanying prospectus supplement.

The price at which you purchase the notes includes costs that the Bank or its affiliates expect to incur and profits that the Bank or its affiliates expect to realize in connection with hedging activities related to the notes. These costs and profits will likely reduce the secondary market price, if any secondary market develops, for the notes. As a result, you may experience an immediate and substantial decline in the market value of your notes on the Original Issue Date.

THE BANK’S ESTIMATED VALUE OF THE NOTES

The Bank’s initial estimated value of the notes set forth on the cover of this pricing supplement is equal to the sum of the values of the following hypothetical components: (1) a fixed-income debt component with the same maturity as the notes, valued using our internal funding rate for structured debt described below, and (2) the derivative or derivatives underlying the economic terms of the notes. The Bank’s initial estimated value does not represent a minimum price at which CIBCWM or any other person would be willing to buy your notes in any secondary market (if any exists) at any time. The internal funding rate used in the determination of the Bank’s initial estimated value generally represents a discount from the credit spreads for our conventional fixed-rate debt. The discount is based on, among other things, our view of the funding value of the notes as well as the higher issuance, operational and ongoing liability management costs of the notes in comparison to those costs for our conventional fixed-rate debt. For additional information, see “Additional Risk Factors—The Bank’s initial estimated value of the notes was not determined by reference to credit spreads for our conventional fixed-rate debt” in this pricing supplement. The value of the derivative or derivatives underlying the economic terms of the notes is derived from the Bank’s or a third party hedge provider’s internal pricing models. These models are dependent on inputs such as the traded market prices of comparable derivative instruments and on various other inputs, some of which are market-observable, and which can include volatility, dividend rates, interest rates and other factors, as well as assumptions about future market events and/or environments. Accordingly, the Bank’s initial estimated value of the notes was determined when the terms of the notes were set based on market conditions and other relevant factors and assumptions existing at that time. See “Additional Risk Factors—The Bank’s initial estimated value does not represent future values of the notes and may differ from others’ estimates” in this pricing supplement.

The Bank’s initial estimated value of the notes is lower than the initial issue price of the notes because costs associated with selling, structuring and hedging the notes are included in the initial issue price of the notes. These costs include the selling commissions paid to CIBCWM and other affiliated or unaffiliated dealers, the projected profits that our hedge counterparties, which may include our affiliates, expect to realize for assuming risks inherent in hedging our obligations under the notes and the estimated cost of hedging our obligations under the notes. Because hedging our obligations entails risk and may be influenced by market forces beyond our control, this hedging may result in a profit that is more or less than expected, or it may result in a loss. We or one or more of our affiliates will retain any profits realized in hedging our obligations under the notes. See “Additional Risk Factors—The Bank’s initial estimated value of the notes is lower than the initial issue price (price to public) of the notes” in this pricing supplement.
