Given Sharp's experience with OTC and filings, since he's been doing it for a long time and has expert knowledge, it would seem rather naïve to think that all 3 of his tickers just happened to miss the deadline and are all now on the EM out of either carelessness or lack of understanding. GS has had ample time to file and get all 3 tickers current long before the deadline.
One has to ask, what advantage is it for GS and the incoming companies to have these tickers go the EM route?
