BK unit nav to Feb 03 = approx: $21.70Keep in mind this is just a guess as I added on some value for the offering .
Last trade @ 13.64 means the premium would have fallen under 2$ , as the effect of the selling after the offering keeps the price below the price paid in the offering = normal action.
Commons would have a value of about $11.70 here ,( just a guess) and the premium would then be 16.6 % or so, and that is lowest premium in quite some time.
