Ann: Appendix 4C - June 2017 Quarter, page-104

Just to add to what you said, if you refer to this reply from IR (Post #:24271233), SYT have a NET 30 – 60 days payment terms.

Hence, the $593k are cash receipts and not total recognized revenue for the whole Q4 2017. Most likely, the invoices issued at the end of June or anytime towards the end of Q4 have not translated into cash receipts for Q4.
