CM Canadian Imperial Bank of Commerce

The notes are being issued by Canadian Imperial Bank of Commerce (“CIBC”). There are important differences between the notes and a conventional debt security, including different investment risks and certain additional costs.

The initial estimated value of the notes as of the pricing date is $9.665 per unit, which is less than the public offering price listed below. See “Summary” on the following page, “Risk Factors” beginning on page TS-6 of this term sheet and “Structuring the Notes” on page TS-15 of this term sheet for additional information. The actual value of your notes at any time will reflect many factors and cannot be predicted with accuracy.

Before you invest, you should read the Note Prospectus, including this term sheet, for information about us and this offering.  Any prior or contemporaneous oral statements and any other written materials you may have received are superseded by the Note Prospectus. Capitalized terms used but not defined in this term sheet have the meanings set forth in product supplement STOCK ARN-1.

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

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 the Starting Value of 100.00, the Participation Rate of 300%, the Capped Value of $12.175 per unit and a range of hypothetical Ending Values. The actual amount you receive and the resulting total rate of return will depend on the actual Ending Value, and whether you hold the notes to maturity. The following examples do not take into account any tax consequences from investing in the notes.

For recent hypothetical values of the Basket, see “The Basket” section below. For recent actual prices of the Basket Stocks, see “The Basket Stocks” section below. The Ending Value will not include any income generated by dividends paid on the Basket Stocks, which you would otherwise be entitled to receive if you invested in those stocks directly. In addition, all payments on the notes are subject to issuer credit risk.

(1)                      The Starting Value was set to 100.00 on the pricing date.

(2)                      The Redemption Amount per unit cannot exceed the Capped Value.

Redemption Amount Calculation Examples

Example 1

The Ending Value is 80.00, or 80.00% of the Starting Value:

Starting Value:                 100.00

Ending Value:                    80.00

Example 2

The Ending Value is 103.00, or 103.00% of the Starting Value:

Starting Value:      100.00

Ending Value:       103.00

§                  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-34 of product supplement STOCK ARN-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 dated March 28, 2017, as supplemented by the discussion under “Summary of Canadian Federal Income Tax Considerations” herein.

The Basket

The Basket is designed to allow investors to participate in the percentage changes of the Basket from the Starting Value to the Ending Value. The Basket Stocks are described in the section entitled “The Basket Stocks” below. Each Basket Stock will be assigned an initial weight on the pricing date, as set forth in the table below.

For more information on the calculation of the value of the Basket, please see the section entitled “Description of ARNs—Basket Market Measures” beginning on page PS-25 of product supplement STOCK ARN-1.

On the pricing date, for each Basket Stock, the Initial Component Weight, the Closing Market Price, the Component Ratio and the initial contribution to the Basket value were as follows:

(1)           These were the Closing Market Prices of the Basket Stocks on the pricing date.

(2)           Each Component Ratio equals the Initial Component Weight of the relevant Basket Stock (as a percentage) multiplied by 100, and then divided by the Closing Market Price of that Basket Stock on the pricing date and rounded to eight decimal places.

The calculation agent will calculate the Ending Value of the Basket by summing the products of the Closing Market Price for each Basket Stock (multiplied by its Price Multiplier) on the calculation day and the Component Ratio applicable to that Basket Stock. The Price Multiplier for each Basket Stock will initially be 1, and is subject to adjustment as described in product supplement STOCK ARN-1. If a Market Disruption Event occurs as to any Basket Stock on the scheduled calculation day, the Closing Market Price of that Basket Stock will be determined as more fully described in the section entitled “Description of ARNs–Basket Market Measures—Ending Value of the Basket” beginning on page PS-26 of product supplement STOCK ARN-1.

While actual historical information on the Basket did exist before the pricing date, the following graph sets forth the hypothetical historical daily performance of the Basket from January 1, 2008 through March 28, 2018. The graph is based upon actual daily historical prices of the Basket Stocks, hypothetical Component Ratios based on the closing prices of the Basket Stocks as of December 31, 2007, and a Basket value of 100.00 as of that date. This hypothetical historical data on the Basket is not necessarily indicative of the future performance of the Basket or what the value of the notes may be. Any hypothetical historical upward or downward trend in the value of the Basket during any period set forth below is not an indication that the value of the Basket is more or less likely to increase or decrease at any time over the term of the notes.

Hypothetical Performance of the Basket

The Basket Stocks

We have derived the following information from publicly available documents. We have not independently verified the accuracy or completeness of the following information.

Because each Basket Stock is registered under the Securities Exchange Act of 1934, each Underlying Company is required to file periodically certain financial and other information specified by the SEC. Information provided to or filed with the SEC by the Underlying Companies can be located at the Public Reference Section of the SEC, 100 F Street, N.E., Room 1580, Washington, D.C. 20549 or through the SEC’s website at http://www.sec.gov by reference to the applicable CIK number set forth below.

This term sheet relates only to the notes and does not relate to any securities of the Underlying Companies. Neither we nor any of our affiliates have participated or will participate in the preparation of the Underlying Companies’ publicly available documents. Neither we nor any of our affiliates have made any due diligence inquiry with respect to the Underlying Companies in connection with the offering of the notes. None of us, MLPF&S or any of our affiliates makes any representation that the publicly available documents or any other publicly available information regarding the Underlying Companies are accurate or complete. Furthermore, there can be no assurance that all events occurring prior to the date of this term sheet, including events that would affect the accuracy or completeness of these publicly available documents that would affect the trading price of the Basket Stocks, have been or will be publicly disclosed. Subsequent disclosure of any events or the disclosure of or failure to disclose material future events concerning the Underlying Companies could affect the value of the Basket Stocks and therefore could affect your return on the notes. Information from outside sources is not incorporated by reference in, and should not be considered part of, this term sheet or any accompanying prospectus, prospectus supplement or product supplement. The selection of the Basket Stocks is not a recommendation to buy or sell shares of the Basket Stocks.

The tables set forth below show the quarterly high and low Closing Market Prices of the shares of the Basket Stocks on their primary exchange from the first quarter of 2008 through the pricing date . We obtained this historical data from Bloomberg L.P.  We have not independently verified the accuracy or completeness of the information obtained from Bloomberg L.P. These historical trading prices may have been adjusted to reflect certain corporate actions such as stock splits and reverse stock splits.

Structuring the Notes

The notes are our debt securities, the return on which is linked to the performance of the Basket. 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, resulted 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 Basket 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 MLPF&S or one of its affiliates. The terms of these hedging arrangements are determined by seeking bids from market participants, including MLPF&S and its affiliates, and take into account a number of factors, including our creditworthiness, interest rate movements, the volatility of the Basket Stocks, 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.

MLPF&S 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 MLPF&S 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 MLPF&S or any third party hedge providers.
