We have been waiting a long while for this deal to complete, part of the reason for this may be that the situation is rather unusual. Normally in the sale of something the vender is enthusiastic to sell the item and the purchaser cautious in buying, hence due dilligence when the purchaser examines the offered item to see if there are gremlins in the works.
So why is this transaction unusual? The answer to this is in that Simon Loh is effectively the seller but would also like to be the buyer for his own account thus he (and his fellow board members who were appointed by him) actually would like to see the purchase by Euronet fail unless he is entirely happy with the price. In actual fact Loh would like to buy the business but at a lower price than Euronet are offering.
For what it is worth I believe that what Loh and his subordinates are doing is trying to discourage Euronet from going through with the purchase thus due dilligence is taking a long time. I think the situation may be at least commical and possibly verging on farce "No, and the lavatory flush needs repairing too" "I'm not sure where the bought ledger is at present, the staff are always loosing it."
