I am work right now and I have not looked at the current POR, however, if it is similar (which I believe it is), then they are a separate class. This class received $50M extra, however are equal to p/k class. Voting, if I recall, was not disclosed or the details were not discussed the last vote.
IMO, I think voting in the H's might be more important. This is a good reason why we should all buy a few, as in 1, 2, 3 4, 5, or whatever you feel like buying (for those do not have any) for voting purposes only.
If I recall, H's voted down the POR by a narrow margin in the previous POR. This time we need to make it a clear vote "No".
I would not worry about DIMEQ because they have no vote and deemed to vote "no".
IMO
