I have absolutely no clue, right now it's Expert Market, so it can only be traded by 'sophisticated investors', no mainstream brokers will allow you to buy it.

They recently filed a Form 15 to deregister its shares and terminate their SEC filing requirements( ie 'go dark') usually an indication they are either giving up completely or will be filing disclosure through OTC Markets instead.

Once in a while you see a Form 15 filed when a public company is acquired in a reverse merger and the acquired company survives as a wholly-owned subsidiary of the acquiror.
