Pink sheet and OTC/BBs are basicly the same thing. They are both a quotetation serivce and not an actual exchange. But, and heres the but, there is one BIG difference. To be listed on the OTC/BBs you have to regester with the SEC and file a history of your finanicals with them, as well as up to date finanicals every quater.
For a company like KATX this would be huge to get listed on the OTC/BBs as it would provide complete company transparncy. People could see exactly where we stand with cash, debt, etc.
Ken knows this and is actively working to get us uplisted to the OTCs/BBs.
