I'm pretty sure it wont matter regardless of the deadline. Any corporate action that CRGP performs will be done by its attorney and most likely behind the scenes. Its nice to see the price action, don't get me wrong, but to me it doesn't matter. Any instruction given to the TA to count the inventory of certificates forces institutional action not retail!
And judging by CRGP history it is very familiar with name and cusip changes which is part of the process to audit and protect our property.
The SEC can not stop a company from protecting its own assets/property no matter the condition.
Holding every single share...no reason to give brokers the ability to reset borrowing from IOU inventory between broker accounts. By holding it essentially puts pressure on their debt volume. And at some point the DTCC will say enough is enough when considering their new margin rules.
