Not sure about the higher exchange....I believe it requires two years of audited financials...last time I talked to RT....and it has been a while...I specifically asked if the financials would be audited and he said no but they could be if needed. Who knows, maybe they decided to spend the money and go for it.
I believe that's been RT's objective from the beginning and the RS was preparation for that... the CE removal amounts to an extra chore for the benefit of shareholders and his pursuit of that is merely for our benefit otherwise a spring or summer move to a higher exchange is the real ambition!
