Actually, if UBS now came forward and said that they now believe
that 100% of their sub-prime exposure will need to be written off
(which is an absurd hypothesis) and they need another 5 billion
from GIC, I would think that its not a bad idea to buy in some
more.
Ceteris paribus, their business model is, after all, fundamentally
sound. Their wealth management business, barring their exposure to
CDO, is world class and their brand equity is second to
none.
