Correct, but Note 2 in the half-yearly report from 28 February 2017, only a few days later, says it is to be paid by 30 June 2017.
This Apollo deal is from December 2012, from memory, so they are now running something like four years late. EVM won't want to break that HOA because Apollo is the only company out of all four deals that has come up with any money.
Also, RD is the chair of Apollo. I personally think there is possibly a conflict there. I've asked what others think about this but I don't recall getting a response.
