70 mil of that 144 mil was for PathUX, which BYOC could get back if they make payments to the PathUx guys. Those payments also can be delayed for awhile, per the terms.
So BYOC did not sell 144 mil shares... actually BYOC and its directors can't sell any restricted shares for awhile, and when they do, they are bound to rule 144.
Discover, who provided the funding to make the S800 acquisition, is the one who is selling. They have been here awhile selling, so hopefully they are almost done.
