Hi Matthias

Let me ask the question in a different way.  The policy says:

> After one year, utilisation of the new assignment must be at least 50%, unless special circumstances are defined.

If the IXP is using less than 50% after one year, what happens?  Will 
the assignment be deassigned?

If the answer is "yes, the assignment will be deassigned", does the RIPE 
NCC apply some form of threshold to determine whether or not to 
deassign?  I.e. if the assignment less than exactly 50%, or is there a 
practical slop factor in there?
