Ann: Expiry of unlisted options and performance rights, page-51

you know that lapse and expire mean the same thing in this context re options
and it was the options that lapsed/expired on 1/12/19 and the performance rights which were cancelled - did you read the announcement? you need to recognise the distinction
and if someone resigned and they were a 'bad leaver' under the option plan then those options would have lapsed at that point, not on the expiry date
it seems obvious someone didnt want to or couldnt afford to spend $90k on exercising
