I have run the math many times. What I recall very clearly is that a $100 million payout to equity markers (P's, K's and commons) will result in just about $10 being paid to each P marker. I cannot recall what a K marker would get, but it is much less than $3.00, more like $0.25.
I believe there is a calculator that Catz linked back in 2012 that shows this. It was on "geishababy".
P's and K's would get 75% of the $100 million.
The old par or face value of any preferred shares, P's or K's, is absolutely irrelevant.
