When the underlying securities of a structured product (excluding baskets ) are normally traded in board lots, the board lots of the structured product at the time of listing shall be such that on exercise or maturity of one board lot of the structured product, the holder of that structured product is entitled to a whole number of board lots of the underlying securities. Structured products that provide for settlement wholly in cash may be issued such that one board lot of the structured product on exercise or maturity entitles the holder to one tenth of a board lot of the underlying security.
