My thoughts, to be taken with a pinch of salt...
The issue date (#8) is the payment date, hence it is tomorrow and not that the document is 'dated' tomorrow as the overall document is dates today. I also believe the issue price of $20ish may be for a lesser number of securities, perhaps those made in the last day - though this would be at a premium to the $16ish close. Looking on londonstockexchange there was ~1m of value traded on 21/04/20 which divided by $20.1 gets in the region of 45,000 - the 1m is heavily rounded by the looks of it
I'm sure someone more clued in than myself will tear this to shreds and maybe the $20 is wishful thinking....
