I believe someone (FUT) has previously advised that the company can buy back shares whenever they want (with notice of such intent), and are not restricted by "insider info" rules - because they ALWAYS have insider info - good or bad. Also, in JT's note in this regard, while he specifically mentions company officers, etc., he didn't mention PTSC itself.
IMO, PTSC the corporation can and should buy back shares with verve.
