I threw my 2 cents out there a week or two ago on this subject, I'll put it out there again for you since you do not seem able or willing to read older posts.
I am thinking there are 2 possibilities on WHY the N's have not been uplisted.
1. The N's will be the only ones left trading in the end and the other 3 will be CASHED OUT.
2. The N's will be CASHED OUT and the other 3 will be the ones still trading in the end.
Again, my thoughts only - as good as anyone elses. AT THIS TIME !!!!
