Rest assurred... Dr. Lee is still, very much, in charge. He will NOT lose his grip on this company. I am sure that future filings will reveal that he is the MAJORITY SHAREHOLDER in the shares to be incorporated from Korea.
I think it's harder for Lee to sign and file the paperwork as CEO for all things related to NASDAQ. Much easier with US born Ian and William completing all things related to financials, filings in the US market...
