The company hasn't mentioned issuing further shares (common or preferred), but it would make sense if they did to fund the pension shortfall. Just an educated guess by some on this board. When? Couldn't say, but management/union/gov't are considering the issue presently. We'll all have to wait and see. :)
They cann't dilute until after they exit BK. There's several post about this if you have the time to search the board. With all Abis equity and less then 60mm shares I'll be happy to accept some diltion and keep my shares.
