I'll have to get back to you. Maybe Catz or someone else knows. I recall that it is about 18.5 for the prefs under the 70/30 split, but it would be around 26-27 if the split goes to 100/0.
"And do we know the impact of DIME on U's yet? If the dilution is massive, it might make sense to vote no. "
Then there is that. No, we don't know, but we will have to know in order to make an informed vote. If the Dimes really eat the commons lunch, you may ultimately find that you get more newco shares with a 100/0 split.
