Len, BBC is on the pink sheets but still files 10Qs and 10Ks. It is a legitimate company but its shares were held improperly....the CEO admitted to owning millions of shares on behalf of other Chinese shareholders. These shareholders kept selling via Form 144; perhaps they knew something, or perhaps they just got lucky.
Ultimately, BBC's business model was flawed. It had problems collecting A/Rs and was ultimately not competitive in its fertilizer market. They have lost biz to other competitors. Its stock has been trashed because of the poor fundamentals and lack of organic growth.
