Not quite.
The news that PP went under federal indictment/investigation was around June 12th in between the CCs that one questions 'what the heck happened'! THATs what happened.
Going under federal investigation with a widening scope changed/limited what Imsc could say or do. One would think the Feds would tell PP to not do much of anything during the federal investigation. This is so basic I am not sure why any investor is wondering 'what happened with the change of tone?' Try federal investigation.
So at a potential crime scene what's the first thing you do? You secure the scene. You can't start moving everything around and changing things because it compromises the evidence and makes it more difficult to figure out what really happened, like deleting emails, wiping servers and crushing hard drives.
Ya think the PP legal problems have anything to do with the 'change in tone and limited ability to make a deal'?
You bet it has.
What was an easy deal in the spring, got more difficult (but doable) after June 12th. Thus the extra time in getting the deal done.
