Isn't it strange he didn't file one when he acquired a billion shares for $11,000 of debt? Yet the Form 4 requirement applies to both sells and buys.
He hasn't put millions into the float as yet - he's restricted by affiliate sales limitations as to how much he can sell based on monthly volumes - which are currently very low - but those shares are now unrestricted and can be dumped into the trading float when circumstances allow.
The Form 5 is a legitimate way of delaying reporting - but I wouldn't be surprised if Doc once again does not adhere to the rules, as he has done many times in the past.
