Actually lower6, that does not appear to be true. The company has only said that"Bztg shareholders are entitled to 1 Buzz Inc share for each Bztg share held.
Entitled indicates that a shareholder can, not that it will automatically happen. What is known is that Shayne, Sunny and the cop have all exchanged theirs and it seems as if the rest of you have not. If it were company initiated, it would have been done for everyone.
As of now, the operating company, Buzz Inc, is no longer owned by BZTG except for small fraction represented by BZTG shares held by the small bagholders. Shayne and company have moved on and I don't see them looking back.
Unless you possess inside information, I think shareholders would be wise to contact the company at once and ask for their shares without further delay. If they don't have to surrender their BZTG shares, what's the harm? Since the OS hasn't changed, perhaps they don't have to exchange them. They can just get their Buzz inc shares. If the company issues the dividend to Buzz Inc shareholders and you don't own Buzz Inc shares on June 30 you are SOL.
