The withholding tax on 280 million dollar transaction is/was 8.6 million dollar. 

not a cent more and not a cent less.

AND it was already paid back in November from the cash GXY had in the bank... remember those 68 million dollar GXY had as per the September report..... $8.4 million dollar came from 68 million dollars, hence the cash in the bank at the end of December quarter was down to 41 million dollars

Either

they stuffed up the December report to show 41 million dollars in the bank and it should have been 41 + 8.4 = 49.4 million dollars in the bank


OR  

they have got today's announcement completely wrong  as you can not pay withholding tax twice on the same transaction.
