Why file it now? Because DDCC management is clueless
DDCC ran for as long as they could as a compliant filing stock scam, until they painted themselves into a corner. No problem they thought - we have the legitimacy aurora around us established. If any filing will get us into trouble, let's just skip the filings. Presto: Legitimacy of a registered Microcrap scam, while behaving like a Pinky.
A year plus later the SEC finally suspends. DDCC management's reaction- No problem! Since the SEC allowed us to get away with multiple pumps the past yr, let's just deregister with a Form 15. Make it official that we are a Pinky, and the SEC will leave us alone for another round of pumps.
As you point out it's a little too late for that nonsense. But if the SEC doesn't act immediately, DDCC might get in a few more pumps. Why would they pump when in theory insiders can't? For the same reason they pumped away during the year of delinquency. Somehow they found a way to hide it. Wake up FINRA!
