The Notes will rank equally with all of our other unsecured and unsubordinated debt obligations. If the Basket Return isgreater than zero, CIBC will pay the principal amount at maturity plus a return equal to the Upside Gearing multiplied by the Basket Return. If the Basket Return is equal to orless than zero but greater than or equal to -25% (the “Trigger Amount”), CIBC will pay the full principal amount at maturity. However, if the Basket Return is less than theTrigger Amount, CIBC will pay less than the full principal amount at maturity, if anything, resulting in a loss of principal that is proportionate to the negative Basket Return. Investing in the Notes involves significant risks. The Notes do not pay any interest. You may lose some or all of your principal amount. Any payment on the Notes,including any repayment of principal at maturity, is subject to the creditworthiness of CIBC. If CIBC were to default on its payment obligations, you may not receiveany amounts owed to you under the Notes and you could lose your entire investment.
