I'm not talking about amending , I'm referring to halting a plan.
Can a plan be terminated or suspended? Unlike amending a plan, a 10b5-1 plan may legally be terminated before its predetermined end date even though the insider is in possession of MNPI (although some brokers' forms prohibit this as a contractual matter).Jan 18, 2013
If there were any serious discussions going on about ARNA being sold or even significant partnerships I have no doubt Amit (or any CEO or insider) would cancel/halt the planned sale. Shareholders wouldn't even be notified the plan was halted or cancelled just as we are not privy to the current plan or price limits within the plan.
