80% is certainly a fungible number and my thought was the probability of closing was higher
from another view, the 20% difference might feel like 50% and it could be that investors misjudge to the downside
that said, if the sale is blocked, the stock might go up b/c liberty keeps some really nice assets...if the sale goes through, nearly $12B goes to buyback as we watch Switzerland (hopefully) turn the corner
net-net, at these levels, I don't see why owning more isn't a good idea?
