If it is the former CEO selling, and there are only a few holders on the register who would have been able to generate the volume we have seen over the last week (and I know a few - but not all - of whom are not currently selling), then that would have to mean he only has 15m, maybe 18m max, left to go. By my rough count there has been 15m-20m shares in the last ten or fifteen days.
If we look at the mismatch between the buyers and sellers, this just about covers that volume (assuming he is liquidating his whole position).
