I think @hopeful99 is correct.
From the 2107 Annual Report (pages 10 & 11, for those playing at home), $50,000 annually plus $15,000 per month or a proportion of that on a pro rata basis (which is maybe where your comes from).

So for 2017:
$50,000
Plus $15,000 x 12
=$230,000 (which shows as $195,000 as salary and $35,000 superannuation)
Plus $193,849 in Equity
And $3,116 in Benefits (eligible FBT benefits?)
=$426,965

While I think its a fair question, for me, I feel they are keeping a cap on expenses and GD is well worth the expense.
But it is Revenue (or not enough of it) and as a direct result the lack of profit, that is the actual problem.
