well, start with AMML, now EGVI, from some months ago:
13:30 11/13/2007 AMMA Americas Shopping Mall Inc Common Stock AMML Americas Shopping Mall Inc New Common Stock 1-100 R/S. Certs below 100 shs will not be reversed & no cert greater than 100 shs will be reversed below 100. **
only one month later Zecco, yes Zecco, did hand out the shares.
second, same class has to be treated the same, ergo all common, all pref A and so on. so no diff if cert or no cert. ...don´t know from where i got this though :)
