You need to read and understand the balance sheet - the $900k is straight from there.
That first point is clearly not related to 30/06/2011 - they have put it in their as the market would have freaked out if they knew the position at 30/06/2011 as it existed then.
They must have received some of the 2 categories of receivables they have used. However it means nothing without a balance sheet to know what creditors are outstanding on whatever date that balance was taken.
