We also refer to an exchange-tradedfund as an “ETF”, a Reference Asset that is a share of an ETF as an “Equity Reference Asset” and a Reference Asset that is an index as an “Index ReferenceAsset”. The Notes will be automatically called if the Closing Value ofeachReference Asset on the Call Observation Date isgreater than or equal toits Call ThresholdValue, which is equal to 100.00% of its Initial Value. If the Notes are automatically called, on the Call Payment Date we will pay a cash payment per Note equal tothe Call Price, which is equal to the Principal Amountplusa percentage return equal to the “Call Return” of 31.60%. Following an automatic call, no furtheramounts will be owed under the Notes.If the Notes are not automatically called (meaning that the Closing Value ofanyReference Asset on the Call Observation Date isless thanits Call Threshold Value), the amount we pay at maturity, if anything, will depend on the Closing Value of each Reference Asset on its Final Valuation Date (its “Final Value”) relativeto its Initial Value and/or its Barrier Value, which is equal to 70.00% of its Initial Value, and the lowest percentage change of the Reference Assets from theirrespective Initial Values to Final Values (the “Least Performing Percentage Change”), calculated as follows:•If the Final Value ofeachReference Asset isgreater thanits Initial Value: Principal Amount of $1,000 + ($1,000 × Least Performing Percentage Change × Leverage Factor)•If the Final Value ofanyReference Asset isless than or equal toits Initial Value and the Final Value ofeachReference Asset isgreater than or equal toitsBarrier Value:$1,000•If, however, the Final Value ofanyReference Asset isless thanits Barrier Value:$1,000 + ($1,000 × Least Performing Percentage Change) If the Notes are not automatically called and the Final Value of any Reference Asset is less than its Barrier Value, investors will suffer a percentage loss on their initial investment that is equal to the Least Performing Percentage Change. Specifically, investors will lose 1% of the Principal Amount of theNotes for each 1% that the Final Value of the Least Performing Reference Asset is less than its Initial Value, and may lose the entire Principal Amount.Any payment on the Notes is subject to our credit risk. The Notes do not pay periodic interest and do not guarantee the payment of the Call Price or the return of the Principal Amount. Investorsare exposed to the market risk of each Reference Asset on the Call Observation Date and the Final Valuation Date and any decline in thevalue of one Reference Asset will not be offset or mitigated by a lesser decline or potential increase in the value of any other ReferenceAsset. If the Notes are not automatically called and the Final Value of any Reference Asset is less than its Barrier Value, investors may loseup to their entire investment in the Notes. Any payment on the Notes is subject to our credit risk. The Notes are unsecured and are not savings accounts or insured deposits of a bank. The Notes are not insured or guaranteed by the Canada Deposit InsuranceCorporation, the U.S. Federal Deposit Insurance Corporation or any other governmental agency or instrumentality of Canada or the United States. The Notes willnot be listed or displayed on any securities exchange or electronic communications network. The Notes have complex features and investing in the Notes involves a number of risks.
