Ann: ABB: Update on Symbio Transaction, page-4

Doesn't look like there is much scope for upside, so it's settling around the low $3s. I think I would prefer all cash too though I'm also a holder of ABB.

You should be able to sell tiny parcels on CommSec, though obviously the brokerage may eat into whatever little you get back. Not sure if CommSec waives brokerage for small parcels on the sell transactions too.
