Yes, record date for warrants is 5 July ( Wednesday) so with T+2 settlement today should be the last opportunity to purchase cum warrants although there is no indication on the Jarden website to that effect.
I just topped up at $1.33 as NTA at 30 June is just under $1.40 so a discount prevails notwithstanding the cum warrant circumstance. Warrants are allotted on Thursday and listed on the NZX on Friday so where they land by the end of the week will be interesting for holders.
