The SEC has nothing to do with the new OTCQB rule. That is OTCMarkets, a for-profit PR company. They have no regulatory authority whatsoever, and their "tiers", including the OTCQB, are meaningless. Just for show. They invented the new rule as a way to charge companies for the illusion that the OTCQB is somehow a legitimate "venture market". By adding non-SEC reporting foreign companies to the OTCQB, they are actually severely diluting the market and making it even less legitimate, if that is possible.
It doesn't matter what "tier" those stocks trade on - they are all Pink Sheets. Paying an extra $10,000 a year is just a waste of money for these companies.
There is really no reason why any non-SEC registered or reporting company should be allowed to trade its shares in the public marketplace. None.
