"Typically when a company is doing a buyback, they put out some news or announcement about it to alert the shareholders."
Typically when an SEC registered company wished 'to do' a divedend distribution or 'stock buy-back', they first have to meet certain financial requirements and apply for approval from the state that has jurisdiction. (where domiciled). Each state has their own laws governing corporate actions.
I suggest you contact the Florida SOS to see if BBRW has applied for, or obtained approval for, a share buy-back yet?
