To those that still question whether PTSC the corporation can buy back shares, first I'll repeat what I've said (and others have said) before: A publicaly traded corporate entity ALWAYS has access to insider information, and that doesn't prohibit them from trading - especially if they announce such intent.
To further the stance that PTSC the corporation CAN buy back shares, again read the words of JT in this "note" about the J settlements:
"In addition, consistent with applicable securities laws and Patriot's insider-trading policy, the company's directors, officers, employees and consultants who have knowledge of the terms of settlement are restricted from trading in PTSC shares until after the company's quarterly financial reports are publicly filed next April."
Notice the specificity in identifying the parties unable to trade. But do you "PTSC" or "the corporation" in there? No. I believe this best answers the question.
FWIW,
