ok, quick:
- 186 million. These are shares issued to Ken and Tim to secure them a controlling block of shares. These are restricted (rule by the SEC) for 12 months. It means they will not flood (sold on) the market and become part of the float (shares that can be bought on the open market).
- Preferred shares, in my knowledge a higher class shares that can be issued to investors for financing deals or other means (these can be tradeable). 1 preferred can convert into multiple common shares. Ken and Tim own these preferred as protection for a hostile takeover.
- Shell is the structure of a company that went bankrupt or doesn't operate anymore. The shell is left. Compare it to a house that is built on nasdaq street. If one moves out of it because cant pay rent, the house becomes empty and someone can buy it and move all its furniture (assets) in it and play on nasdaq street.
If a company wants to go public they can go the official route (and build the house brick for brick). Or just buy a shell, quicker and cheaper.
BVIG our shell, is a clean shell as the former company never operated. Clean as in, no dept's, patent conflcits and what not.
investopedia.com is a good source to read about all these in comprehensible layman's words.
