Yokka,
Be a little careful on the $4m, some detail of which is (I seem to recall) in the AR.
Most of that $ is trading and physical market collateral (prudential guarantee), and therefore locked up from a company point of view. Page 5 of the 4C (at the bottom of the text) mentions prudentials and equity in transit. Equity was only 263k, so most is prudential.
They do (IMO) need to raise cash, hence the suspension.
