Industry's response, page-4

Thanks @septic1

Their math is wrong however.  They took the gross profit figure of $11.3m from page 3 of the HY19 report - which is ok.
However, page 14 shows the detailed breakdown by division:

Gross revenue for the half year was: $52.999m (of which $6.2m was via grandfathered commissions)
Commissions paid was:                    ($41.9m)
Net revenue / Gross Profit:                 $11.3m

Without grandfathered commissions at 100% gross profit margin implies gross profit would decline from $11.3m to $5.1m.

This doesn't mean you have to double what you charge advisers.  It simply means you have to replace $6.2m (or $12.4m for the full year), which you previously received via rebates to a new charge.  As I posted earlier, this equates to $5k per Authorised Rep.  Or have I got it wrong?
