Payment at maturity:

You will receive at maturity a cash payment per Trigger PLUS as follows:

If the final basket value is greater than the initial basket value:

$1,000 + leveraged upside payment

If the final basket value is less than or equal to the initial basket value but is greater than or equal to the downside threshold value:

$1,000

If the final basket value is less than the downside threshold value:

$1,000 × basket performance factor

Under these circumstances, the payment at maturity will be less than the stated principal amount of $1,000 and will represent a loss of more than 20%, and possibly all, of your investment.

Initial basket value:

100

Final basket value:

The basket closing value on the valuation date

The basket closing value on any day is the sum of the products of the basket component closing value of each underlying index times the applicable multiplier for such underlying index on such date.

Basket component closing value:

In the case of each underlying index, the index closing value of such underlying index.

Multiplier:

Each multiplier will be set on the pricing date based on the applicable underlying index's respective initial basket component value so that each underlying index will represent its applicable basket component weighting in the predetermined initial basket value. Each multiplier will remain constant for the term of the Trigger PLUS and will equal, for each underlying index, (i) the product of the applicable basket component weighting times 100 divided by (ii) the applicable initial basket component value.
