If the closing price of the reference shares on the relevant exchange is less than the knock-in level at any time from but not including the trade date to and including the valuation date and the final share price is lower than the initial share price at maturity, you will not be paid 100% of the principal amount of your securities.

At maturity, you will under no circumstances receive more than the principal amount of your securities, and the total payment you receive over the term of the securities will never exceed the principal amount of the securities plus the coupon payments paid during the term of the securities.
