Risk Factors

Please see the Preliminary Offering Documents for a description of certain risks related to this investment, including, but not limited to, the following:

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

·     Payments on the notes, including repayment of principal, are subject to the credit risk of CIBC, and actual or perceived changes in the creditworthiness of CIBC are expected to affect the value of the notes. If CIBC becomes insolvent or is unable to pay its obligations, you may lose your entire investment.

·     Your investment return is limited to the return represented by the Capped Value and may be less than a comparable investment directly in the Basket Stocks.

·     Changes in the prices of the Basket Stocks may offset each other.

·     The initial estimated value of the notes on the pricing date will be less than their public offering price.

·     If you attempt to sell the notes prior to maturity, their market value may be lower than both the public offering price and the initial estimated value of the notes on the pricing date.

·     You will have no rights of a holder of the Basket Stocks, and you will not be entitled to receive shares of the Basket Stocks or dividends or other distributions by the issuers of the Basket Stocks.

·     We do not control any company included in the Basket and have not verified any disclosure made by any such company. The companies included in the Basket will have no obligations relating to the notes.

·     The Redemption Amount will not be adjusted for all corporate events that could affect the Basket Stocks.

·     The Basket is concentrated in the financial sector and an investment in the notes involves certain risks associated with an investment in companies in the financial sector.
