Unless the Notes were previously called, BNS will pay a coupon on each coupon payment date regardless of the performance of the underlying asset. BNS will automaticallycall the Notes early if the closing level of the underlying asset on any observation date prior to the final valuation date is equal to or greater than the call threshold level, which is a level of the underlying asset equalto a percentage of the initial level, as indicated below. If the Notes are subject to an automatic call, BNS will pay you on the coupon payment date corresponding to the relevant observation date (the “call settlementdate”) a cash payment per Note equal to the principal amount plus the coupon otherwise due, and no further payments will be owed to you under the Notes. If the Notes are not subject to an automatic call and theclosing level of the underlying asset on the final valuation date (the “final level”) is equal to or greater than the conversion level, BNS will pay you a cash payment per Note at maturity equal to the principal amount.If, however, the Notes are not subject to an automatic call and the final level is less than the conversion level, BNS will deliver to you at maturity a number of shares of the underlying asset per Note equal to thequotient of (i) the principal amount divided by (ii) the conversion level (rounded to the nearest ten-thousandth of one share, the “share delivery amount”), the value of which is expected to be worth less than yourprincipal amount and, in extreme situations, you could lose your entire investment.
