I reckon it would be a teething problem with getting sellers linked and having a mechanism in place two handle the exchange rate - given that exchange rates are floating.
You'd think the ASX would have some sort of computer facilitated process but maybe it takes some setting up. I know Eric Sprott said (couple of weeks ago) the were delays with the ASX & set up issues. This may be a flow on from that? I certainly don't see it as deliberate or contrived on the part of KLA ..... That's just my opinion.
