I agree that this was in the existing share structure(PR today indicated such) which was. 3.9 billion plus shares IR got......so 4.3 billion roughly....but weren't they listed as restricted outstanding...if they go to preferred then the O/S is reduced.....
The exchanges may have been detailed to some extent, but the fact remains you can't convert a preferred share out of nothing. It has to come from something. Commons are converted according to a ratio, and after that, they can't still exist alongside the preferreds. That's my common-sense world of physics POV.
