Summary

The Leveraged Index Return Notes^® Linked to the Bloomberg Commodity Index^SM, due September  , 2028 (the “notes”) are our senior unsecured debt securities. The notes are not guaranteed or insured by the Canada Deposit Insurance Corporation, the U.S. Federal Deposit Insurance Corporation or any other governmental agency of the United States, Canada or any other jurisdiction or secured by collateral. The notes are not bail-inable debt securities (as defined on page 6 of the prospectus). The notes will rank equally with all of our other unsecured and unsubordinated debt. Any payments due on the notes, including any repayment of principal, will be subject to the credit risk of CIBC. The notes provide you a leveraged return, if the Ending Value of the Market Measure, which is the Bloomberg Commodity Index^SM (the “Index”), is greater than the Starting Value. If the Ending Value is less than the Starting Value, you will lose all or a portion of the principal amount of your notes. Any payments on the notes will be calculated based on the $10 principal amount per unit and will depend on the performance of the Index, subject to our credit risk. See “Terms of the Notes” below.

The economic terms of the notes (including the Participation Rate) are based on our internal funding rate, which is the rate we would pay to borrow funds through the issuance of market-linked notes, and the economic terms of certain related hedging arrangements. Our internal funding rate is typically lower than the rate we would pay when we issue conventional fixed rate debt securities. This difference in funding rate, as well as the underwriting discount and the hedging-related charge and certain service fee described below, will reduce the economic terms of the notes to you and the initial estimated value of the notes on the pricing date. Due to these factors, the public offering price you pay to purchase the notes will be greater than the initial estimated value of the notes.

On the cover page of this term sheet, we have provided the initial estimated value range for the notes. This initial estimated value range was determined based on our pricing models. The initial estimated value as of the pricing date will be based on our internal funding rate on the pricing date, market conditions and other relevant factors existing at that time, and our assumptions about market parameters. For more information about the initial estimated value and the structuring of the notes, see “Structuring the Notes” on page TS-14.

Investor Considerations

You may wish to consider an investment in the notes if:

· You anticipate that the Index will increase from the Starting Value to the Ending Value.

· You are willing to risk a loss of principal if the Index decreases from the Starting Value to the Ending Value.

· You are willing to forgo the interest payments that are paid on conventional interest bearing debt securities.

· You are willing to forgo the rights and benefits of owning the commodities or the futures contracts included in, or tracked by, the Index.

· You are willing to accept a limited or no market for sales prior to maturity, and understand that the market prices for the notes, if any, will be affected by various factors, including our actual and perceived creditworthiness, our internal funding rate and fees and charges on the notes.

· You are willing to assume our credit risk, as issuer of the notes, for all payments under the notes, including the Redemption Amount.

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

· You believe that the Index will decrease from the Starting Value to the Ending Value or that it will not increase sufficiently over the term of the notes to provide you with your desired return.

· You seek principal repayment or preservation of capital.

· You seek interest payments or other current income on your investment.

· You want to receive the rights and benefits of owning the commodities or the futures contracts included in, or tracked by, the Index.

· You seek an investment for which there will be a liquid secondary market.

· You are unwilling or are unable to take market risk on the notes or to take our credit risk as issuer of the notes.

We urge you to consult your investment, legal, tax, accounting, and other advisors before you invest in the notes.

Hypothetical Payout Profile and Examples of Payments at Maturity

The graph below is based on hypothetical numbers and values.

Leveraged Index Return Notes®

This graph reflects the returns on the notes, based on the Threshold Value of 100% of the Starting Value and a hypothetical Participation Rate of 220.00% (the midpoint of the Participation Rate range of [210.00% to 230.00%]). The green line reflects the returns on the notes, while the dotted gray line reflects the returns of a direct investment in the Index. This graph has been prepared for purposes of illustration only.

The following table and examples are for purposes of illustration only. They are based on hypothetical values and show hypothetical returns on the notes. They illustrate the calculation of the Redemption Amount and total rate of return based on a hypothetical Starting Value of 100.00, a hypothetical Threshold Value of 100.00, a hypothetical Participation Rate of 220.00% and a range of hypothetical Ending Values. The actual amount you receive and the resulting total rate of return will depend on the actual Starting Value, Threshold Value, Ending Value and Participation Rate, and whether you hold the notes to maturity. The following examples do not take into account any tax consequences from investing in the notes.

For recent actual levels of the Index, see “The Index” section below. In addition, all payments on the notes are subject to issuer credit risk.

Ending Value	Percentage Change from the Starting Value to the Ending Value	Redemption Amount per Unit(1)	Total Rate of Return on the Notes

Risk Factors

There are important differences between the notes and a conventional debt security. An investment in the notes involves significant risks, including those listed below. You should carefully review the more detailed explanation of risks relating to the notes in the “Risk Factors” sections beginning on page PS-6 of product supplement COMM LIRN-1, page S-1 of the prospectus supplement, and page 1 of the prospectus identified above. We also urge you to consult your investment, legal, tax, accounting, and other advisors before you invest in the notes.

Structure-related Risks

§ Depending on the performance of the Index as measured shortly before the maturity date, you may lose up to 100.00% of the principal amount.

§ Your investment return may be less than a comparable investment directly in any related futures contract.

§ Your return on the notes may be less than the yield you could earn by owning a conventional fixed or floating rate debt security of comparable maturity.

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

Valuation- and Market-related Risks

§ Our initial estimated value of the notes will be lower than the public offering price of the notes. The public offering price of the notes will exceed our initial estimated value because costs associated with selling and structuring the notes, as well as hedging the notes, all as further described in “Structuring the Notes” on page TS-14, are included in the public offering price of the notes.

§ Our initial estimated value does not represent future values of the notes and may differ from others’ estimates. Our initial estimated value is only an estimate, which will be determined by reference to our internal pricing models when the terms of the notes are set. This estimated value will be based on market conditions and other relevant factors existing at that time, our internal funding rate on the pricing date and our 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 our 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 the Index, our creditworthiness, interest rate movements and other relevant factors, which may impact the price at which MLPF&S, BofAS or any other party would be willing to buy notes from you in any secondary market transactions. Our estimated value does not represent a minimum price at which MLPF&S, BofAS or any other party would be willing to buy your notes in any secondary market (if any exists) at any time.

§ Our initial estimated value of the notes will not be determined by reference to credit spreads for our conventional fixed-rate debt. The internal funding rate to be used in the determination of our 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 we were to use 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 would have an adverse effect on the economic terms of the notes, the initial estimated value of the notes on the pricing date, and any secondary market prices of the notes.

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

Conflict-related Risks

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

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

Market Measure-related Risks

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

§ Ownership of the notes will not entitle you to any rights with respect to any commodities or futures contracts represented by or included in the Index.

§ The prices of commodities or futures contracts represented by or included in the Index may change unpredictably, affecting the value of your notes in unforeseeable ways.

§ Suspension or disruptions of market trading in the related commodities and futures contracts may adversely affect the value of the notes.

§ Changes in exchange methodology may adversely affect the value of the notes.

§ Legal and regulatory changes could adversely affect the return on and value of your notes.

§ The notes will not be regulated by the U.S. Commodity Futures Trading Commission.

§ The Index includes futures contracts traded on foreign exchanges, which may be less regulated than U.S. markets and may involve different and greater risks than trading on U.S. exchanges.

§ Exchange rate movements may adversely impact the value of notes.

Tax-related Risks

§ The U.S. federal income tax consequences of the notes are uncertain, and may be adverse to a holder of the notes. See “Summary of U.S. Federal Income Tax Consequences” below and “U.S. Federal Income Tax Summary” beginning on page PS-30 of product supplement COMM LIRN-1. For a discussion of the Canadian federal income tax consequences of investing in the notes, see “Material Income Tax Consequences—Canadian Taxation” in the prospectus, as supplemented by the discussion under “Summary of Canadian Federal Income Tax Considerations” herein.

Additional Risk Factors

The Index tracks commodity futures contracts and does not track the spot prices of the Index Commodities.

The Index is composed of exchange-traded futures contracts (the “Index Components”) on physical commodities (the “Index Commodities”). Unlike equities, which typically entitle the holder to a continuing stake in a corporation, a commodity futures contract is typically an agreement to buy a set amount of an underlying physical commodity at a predetermined price during a stated delivery period. A futures contract reflects the expected value of the underlying physical commodity upon delivery in the future. In contrast, the underlying physical commodity’s current or “spot” price reflects the immediate delivery value of the commodity.

The notes are linked to the Index and not to the spot prices of the Index Commodities. An investment in the notes is not the same as buying and holding the Index Commodities. While price movements in the Index Components may correlate with changes in the spot prices of the Index Commodities, the correlation will not be perfect and price movements in the spot markets for the Index Commodities may not be reflected in the futures market (and vice versa). Accordingly, an increase in the spot prices of the Index Commodities may not result in an increase in the prices of the Index Components or the level of the Index. The prices of the Index Components and the level of the Index may decrease while the spot prices for the Index Commodities remain stable or increase, or do not decrease to the same extent.

Higher future prices of the Index Components relative to their current prices may have a negative effect on the level of the Index and therefore the value of the notes.

Commodity indices generally reflect movements in commodity prices by measuring the value of futures contracts for the applicable commodities. To maintain the Index, as futures contracts approach expiration, they are replaced by similar contracts that have a later expiration. This process is referred to as “rolling.” The level of the Index is calculated as if the expiring futures contracts are sold and the proceeds from those sales are used to purchase longer-dated futures contracts.

The difference in the price between the contracts that are sold and the new contracts for more distant delivery that are purchased is called “roll yield,” and the change in price that contracts experience while they are components of the Index is sometimes referred to as “spot return.”

If the expiring futures contract included in the Index is “rolled” into a less expensive futures contract with a more distant delivery date, the market for that futures contract is trading in “backwardation.” In this case, the effect of the roll yield on the level of the Index will be positive because it costs less to replace the expiring futures contract. However, if the expiring futures contract included in the Index is “rolled” into a more expensive futures contract with a more distant delivery date, the market for that futures contract is trading in “contango.” In this case, the effect of the roll yield on the level of the Index will be negative because it will cost more to replace the expiring futures contract.

There is no indication that the markets for the Index Components will consistently be in backwardation or that there will be a positive roll yield that increases the level of the Index. It is possible, when near-term or spot prices of the Index Components are decreasing, for the level of the Index to decrease significantly over time even when some or all of the Index Components are experiencing backwardation. If all other factors remain constant, the presence of contango in the market for an Index Component could result in negative roll yield, which could decrease the level of the Index and the value of the notes.

Risks associated with the Index may adversely affect the market price of the notes.

The annual composition of the Index will be calculated in reliance upon historic price, liquidity, and production data that are subject to potential errors in data sources or errors that may affect the weighting of the Index Components. The Index sponsor may not discover every discrepancy and any discrepancies that require revision will not be applied retroactively. These discrepancies may adversely affect the level of the Index and the market price of the notes.

The notes are linked to an excess return index and not a total return index.

The notes are linked to an excess return index and not a total return index. An excess return index, such as the Index, reflects the returns that are potentially available through an unleveraged investment in the contracts composing that index. By contrast, a “total return” index, in addition to reflecting those returns, also reflects interest that could be earned on funds committed to the trading of the underlying futures contracts.

The Index

All disclosures contained in this term sheet regarding the Index have been derived from publicly available sources, which we have not independently verified. The information reflects the policies of, and is subject to change by, Bloomberg Index Services Limited (“BISL” or the “Index sponsor”). The Index sponsor, which licenses the copyright and all other rights to the Index, has no obligation to continue to publish, and may discontinue publication of, the Index. The consequences of the Index sponsor discontinuing publication or determination of the Index are discussed in the section entitled “Description of LIRNs— Discontinuance of a Market Measure” on page PS-22 of product supplement COMM LIRN-1. None of us, the calculation agent, MLPF&S or BofAS accepts any responsibility for the calculation, maintenance or publication of the Index or any successor.

General

The Index is currently composed of 23 Index Components on 21 Index Commodities. It is quoted in U.S. dollars and reflects the return of underlying commodity futures price movements only. It reflects the returns that are potentially available through an unleveraged investment in the futures contracts on Index Commodities comprising the Index as described below. The value of the Index is computed on the basis of hypothetical investments in the basket of commodities that make up the Index.

The Index was previously known as the Dow Jones–UBS Commodity Index^SM. The Index was created by AIG International Inc. in 1998, acquired by UBS in May 2009, administered by Bloomberg starting in 2014. Bloomberg acquired the Index in September 2020.

Index Governance, Audit and Review Structure

BISL uses two primary committees to provide overall governance and oversight of its benchmark administration activities:

· The product, risk and operations committee provides direct governance and is responsible for the first line of controls over the creation, design, production and dissemination of benchmark indices, strategy indices and fixings administered by BISL, including the Index. The product, risk and operations committee is composed of Bloomberg personnel with significant experience or relevant expertise in relation to financial benchmarks. Meetings are attended by Bloomberg legal & compliance personnel. Nominations and removals are subject to review by Bloomberg’s benchmark oversight committee, discussed below.

· The oversight function is provided by the benchmark oversight committee. The benchmark oversight committee is independent of the product, risk and operations committee and is responsible for reviewing and challenging the activities carried out by the product, risk and operations committee. In carrying out its oversight duties, the benchmark oversight committee receives reports of management information both from the product, risk and operations committee as well as Bloomberg legal and compliance members engaged in second level controls.

On a quarterly basis, the product, risk and operations committee reports to the benchmark oversight committee on governance matters, including but not limited to client complaints, the launch of new benchmarks, operational incidents (including errors & restatements), major announcements and material changes concerning the benchmarks, the results of any reviews of the benchmarks (internal or external) and material stakeholder engagements.

Composition of the Index

Commodities Available for Inclusion in the Index. Commodities are selected for the Index that are believed to be both sufficiently significant to the world economy to merit consideration and that are tradable through a qualifying related futures contract. With the exception of several metals contracts (aluminum, lead, tin, nickel and zinc) that trade on the London Metals Exchange (“LME”) and the contract for Brent Crude Oil and Low Sulphur Gas Oil, each of the commodities is the subject of at least one futures contract that trades on a U.S. exchange. Twenty-five commodities are considered to be eligible for inclusion in the Index. They are: aluminum, cocoa, coffee, copper, corn, cotton, crude oil (WTI crude and Brent crude), gold, ultra-low-sulfur diesel (heating oil), lead, lean hogs, live cattle, low sulphur gas oil, natural gas, nickel, platinum, silver, soybean meal, soybean oil, soybeans, sugar, tin, unleaded gasoline, wheat (Soft (Chicago) wheat and Hard Red Winter (Kansas City) wheat) and zinc.

The twenty-one commodities represented in the Index for 2022 are: aluminum, coffee, copper, corn, cotton, crude oil (WTI crude and Brent crude), gold, ultra-low-sulfur diesel (heating oil), lean hogs, live cattle, low sulfur gas oil, natural gas, nickel, silver, soybean meal, soybean oil, soybeans, sugar, unleaded gasoline, wheat (Soft (Chicago) wheat and Hard Red Winter (Kansas City) wheat) and zinc.

Designated Contracts for Each Commodity. One or more commodity contracts known as “designated contracts” are selected by BISL for each commodity. With the exception of several LME contracts, which are traded in London, low sulphur gas oil, which is traded on the ICE Futures Europe, in London, crude oil, for which two designated contracts have been selected, and wheat for which two designated contracts that are traded in North America have been selected, BISL selects for each index commodity one commodity contract that is traded in North America and denominated in U.S. dollars. Data concerning the designated contracts will be used to calculate the Index. It is possible that BISL will in the future select more than one designated contract for additional commodities or may select designated contracts that are traded outside of the United States or in currencies other than the U.S. dollar. For example, in the event that changes in regulations concerning position limits materially affect the ability of market participants to replicate the Index in the underlying futures markets, it may become appropriate to include multiple designated contracts for one or more commodities (in addition to crude oil and wheat) in order to enhance liquidity. The termination or replacement of a commodity contract on an established exchange occurs infrequently; if a designated contract were to be terminated or replaced, a comparable commodity contract would be selected, if available, to replace the designated contract.

The Index also includes primary (base commodities that are not principally derived or produced from other commodities) and derivative commodities (commodities that are principally derived or produced from other commodities). Adjustments are made to avoid the “double-counting” of primary commodities that would result if primary commodities and derivative commodities were viewed as wholly separate categories. BISL, as index administrator, may determine that other index commodities qualify as derivative commodities in the future, resulting in similar adjustments. The current primary and derivative commodities are:

Primary Commodity	Derivative Commodities
Crude Oil (WTI and Brent)	ULS Diesel, RBOB Gasoline and Low Sulphur Gas Oil
Soybeans	Soybean Oil and Soybean Meal

Annual Reconstitution and Rebalancing of the Index

The Index is reconstituted and rebalanced each year in January on a price-percentage basis. The annual constitution and weightings for the Index are determined each year by BISL employees operating within the product, risk and operations committee under the oversight of the benchmark oversight committee. Once approved, the new composition of the Index is publicly announced, and takes effect in the month of January immediately following the announcement.

Determination of Relative Weightings. The relative weightings of the designated contracts that are eligible for inclusion in the Index are determined annually according to both liquidity and dollar-adjusted production data in 2/3 and 1/3 shares, respectively. Each year, for each designated contract eligible for inclusion in the Index, liquidity is measured by the commodity liquidity percentage (which we refer to as the CLP) and production by the commodity production percentage (which we refer to as the CPP). The CLP for each commodity is determined by taking a five-year average of the product of trading volume and the historic dollar value of the designated contract for that commodity, and dividing the result by the sum of such products for all commodities which were designated for potential inclusion in the Index, except that LME volume is divided by three in order to make a more appropriate comparison to U.S. exchange data and that the COMEX price and the LME volume is used for copper, which requires adjusting the COMEX prices to metric tons. In contrast to U.S. futures, which are typically listed on a monthly or bimonthly basis and trade only during specific hours, LME contracts can be traded over-the-counter, 24 hours a day, for value on any business day within a three-month window extending out from spot. In addition, LME contracts can be traded for settlement on the third Wednesday of each month extending out 27 months from the date the contract is made. Accordingly, historical data comparable to that of U.S. futures contracts is not available for these LME contracts and certain adjustments to the available data are made for purposes of calculating this component of the Index. In particular, LME contracts that trade on the third Wednesday of each month will serve as a proxy for U.S. futures contracts. The calculation of the Index utilizes the LME contracts that trade on the third Wednesday of every other month, starting with January.

The CPP is determined for each designated contract by taking a five-year average of annual world production figures (the most recent five years for which data is available), adjusted by the historic dollar value of the designated contract, and dividing the result by the sum of such production figures for all designated contracts. Data for derivative commodities is not included in production data to avoid double-counting and, where there are multiple designated contracts for a particular commodity, the production data is allocated at this stage to only one designated contract also to avoid double-counting. Production weightings are allocated among derivative commodities and primary commodities, and between multiple contracts where applicable, before the final weightings are determined. In addition, for natural gas, only North American production is used.

The CLP and the CPP are then combined (using a ratio of 2/3 CLP plus 1/3 CPP) to establish an interim commodity index percentage for each designated contract. The Index is designed to provide diversified exposure to commodities as an asset class. To ensure that no single commodity or commodity sector dominates the Index, the following diversification rules are applied to the annual reweighting and rebalancing of the Index as of January of the applicable year:

§ No designated contract may constitute less than 0.4% of the Index; designated contracts which constitute less than 0.4% of the Index will be removed from the Index.

§ No single commodity together with its derivatives (together, a “commodity sector”) (e.g., crude oil together with ULS Diesel and unleaded gasoline or soybeans together with soybean meal and soybean oil), may constitute more than 25% of the Index. Any excess weight is generally allocated equally to other commodities not affected by this rule, while treating commodity sectors as one asset when distributing the excess.

§ No single commodity (e.g., natural gas or silver) may constitute more than 15% of the Index (note that both crude oil designated contracts and both wheat designated contracts are considered together as one commodity for this purpose). Any excess weight is generally allocated equally to other commodities not affected by this rule, while treating commodity sectors as one asset when distributing the excess

§ No related group of commodities designated as a “commodity group” above (e.g., energy, precious metals, livestock, or grains) may constitute more than 33% of the Index. Any excess weight is generally allocated equally to other commodities not affected by this rule, while treating commodity sectors as one asset when distributing the excess.

§ Gold and silver will be given a weight equal to their CLPs (subject to the 25% commodity sector and 15% commodity limits). The sum of the difference between weights based on the interim percentage and the weights based on the CLPs generally will be subtracted from the other commodity sectors equally, while treating commodity sectors as one asset when subtracting the excess.

§ No single commodity (e.g., natural gas, silver) may constitute less than 2% of the Index. If one or more single commodities have a weight less than 2% of the Index, the sum of the difference between the 2% and the actual weights generally will be subtracted from the other designated contracts equally and reallocated so that no single commodity has a weight less than 2%.

§ The ratio of the interim percentage to the CLP for a designated contract may not exceed 3.5:1. The excess weight for all affected designated contracts is aggregated, and is generally allocated equally to other commodities with such a ratio below a certain number, currently set at 2.0.

Following the annual reconstitution and rebalancing of the Index in January, the percentage of any single commodity or group of commodities at any time prior to the next reconstitution or rebalancing will fluctuate and may exceed or be less than the percentages set forth above.

Commodity Index Multipliers. Following application of the diversification rules discussed above, the target weights are incorporated into the Index by calculating the new unit weights for each designated contract included in the Index. On the fourth Index business day of the year, the target weights, along with the settlement values on that date for designated contracts included in the Index, are used to determine a commodity index multiplier (which we refer to as the CIM) for each designated contract included in the Index. This CIM is used to achieve the percentage weightings of the commodities included in the Index, in U.S. dollar terms, indicated by their respective target weights. After the CIMs are calculated, they remain fixed throughout the year. As a result, the observed price percentage of each commodity included in the Index will float throughout the year, until the CIMs are reset the following year based on new target weights. An “Index business day” refers to a day on which the sum of the CIPs for those index commodities that are open for trading is greater than 50%.

Index Calculations

The Index is calculated on an excess return basis. BISL calculates the Index by applying the impact of the changes to the prices of futures contracts included in the Index (based on their relative weightings). Once the CIMs are determined as discussed above, the calculation of the Index is a mathematical process whereby the CIMs for the commodities included in the Index are multiplied by respective prices in U.S. dollars for the applicable designated contracts. These products are then summed. The percentage change in this sum is then applied to the immediately preceding index value to calculate the then current index value.

The Index Is a Rolling Index. The Index is composed of futures contracts rather than Index Commodities. Unlike equities, which typically entitle the holder to a continuing stake in a corporation, futures contracts normally specify a certain date for the delivery of the underlying physical commodity. In order to avoid delivering the underlying Index Commodities and to maintain exposure to the underlying Index Commodities, periodically contracts on Index Commodities specifying delivery on a nearby date must be sold and contracts on Index Commodities that have not yet reached the delivery period must be purchased. The rollover for each futures contract occurs over a period of five Index business days each month according to a pre-determined schedule. This process is known as “rolling” a futures contract position. The Index is, therefore, a “rolling index”.

Index Calculation Disruption Events. From time to time, disruptions can occur in trading futures contracts on various commodity exchanges. The daily calculation of the Index will be adjusted in the event that BISL determines that any of the following index calculation disruption events exists:

· termination or suspension of, or material limitation or disruption in the trading of any futures contract or first nearby futures contract used in the calculation of the Index on that day,

· the settlement value of any futures contract used in the calculation of the Index reflects the maximum permitted price change from the previous day’s settlement value,

· the failure of an exchange to publish official settlement values for any futures contract used in the calculation of the Index, or

· with respect to any futures contract used in the calculation of the Index that trades on the LME, a business day on which the LME is not open for trading.

If an index calculation disruption event occurs on any Index business day during a hedge roll period (which we define as the fifth through ninth Index business day of each month) in any month other than January affecting any futures contract included in the Index, the portion of the roll that would have taken place on that Index business day is deferred until the next Index business day on which such conditions do not exist. If any of these conditions exist throughout the hedge roll period, the roll with respect to the affected contract will be effected in its entirety on the next Index business day on which such conditions no longer exist. The index calculation disruption event will not postpone the roll for any other futures contract for which an index calculation disruption event has not occurred.

In the event that an index calculation disruption event occurs during the hedge roll period scheduled for January of each year affecting a futures contract included in the Index, the rolling or rebalancing of the relevant designated contract will occur in all cases over five Index business days on which no index calculation disruption event exists. The hedge roll period in January, and the resulting rebalancing that is occurring, will be extended if necessary until the affected designated contract finishes rolling over five Index business days. The amounts of a particular futures contract rolled or rebalanced in January will always be distributed over five Index business days, and rolling weight at the rate of 20% per Index business day on any Index business day following an index calculation disruption event during such hedge roll period. This change affects only the rolling or rebalancing process in January, with no change to the rules for rolling futures contracts in other monthly hedge roll periods.

Supplement to the Plan of Distribution

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

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

We will pay a fee to a broker dealer in which an affiliate of BofAS has an ownership interest for providing certain services with respect to this offering, which will reduce the economic terms of the notes to you.

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

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

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

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

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

Structuring the Notes

The notes are our debt securities, the return on which is linked to the performance of the Index. As is the case for all of our debt securities, including our market-linked notes, the economic terms of the notes reflect our actual or perceived creditworthiness at the time of pricing. The internal funding rate we use in pricing the market-linked notes is typically lower than the rate we would pay when we issue conventional fixed-rate debt securities of comparable maturity. This difference 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. This generally relatively lower internal funding rate, which is reflected in the economic terms of the notes, along with the fees and charges associated with market-linked notes, typically results in the initial estimated value of the notes on the pricing date being less than their public offering price.

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

BofAS has advised us that the hedging arrangements will include a hedging-related charge of approximately $0.075 per unit, reflecting an estimated profit to be credited to BofAS from these transactions. Since hedging entails risk and may be influenced by unpredictable market forces, additional profits and losses from these hedging arrangements may be realized by BofAS or any third party hedge providers.

Summary of 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 term sheet 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 CIBC 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 CIBC for purposes of the thin capitalization rules in the Canadian Tax Act; and (f) is not an entity in respect of which CIBC 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 CIBC 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.

Summary of U.S. Federal Income Tax Consequences

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, or in some cases supplements, the discussion entitled “U.S. Federal Income Tax Summary” in product supplement COMM LIRN-1, which you should carefully review prior to investing in the notes.

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 cash-settled 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, redemption or payment on maturity in an amount equal to the difference between the amount you receive at such time and the amount that you paid for your notes. Such gain or loss should generally be long-term capital gain or loss if you have held your notes for more than one year. Non-U.S. holders should consult the section entitled “U.S. Federal Income Tax Summary – Non-U.S. Holders” in product supplement COMM LIRN-1.

The expected characterization of the notes is not binding on the U.S. Internal Revenue Service (the “IRS”) or the courts. Thus, it is possible that the IRS would seek to characterize your notes in a manner that results in tax consequences to you that are different from those described above or in the accompanying product 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 your notes and certain other considerations with respect to your investment in the notes, you should consider the discussion set forth in “U.S. Federal Income Tax Summary” of the product 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.
