no facts here, however my opinion is that they set up the buy back this way in order to be able to purchase directly from S and L, so as to keep them below the 10% level they must stay at. I can`t see PTSC buying other shares, that would put S and L above the 10% mark.....and that is the set up rules.
That is not fact, just my opionin.......I don`t believe you can get the exact fact anyway.
