  • Market Participants wishing to exercise Peak Q1 options may do so at any time during the trading day by notifying their ASX 24 CLEARING PARTICIPANT who will lodge an Exercise Request with the exchange. The assignment notification (to your ASX 24 Clearing Participant) will occur no later than 45 minutes prior to the commencement of trading on the next Business Day.
  • Market Participants wishing to exercise Calendar options prior to the last trading day may do so by notifying their ASX 24 CLEARING PARTICIPANT who will lodge an Exercise Request with the Exchange PRIOR TO 1:30PM on any given day.
