You're going to want to refer to Rule 10b-18, which is the SEC rule governing repurchases, and the Florida Business Corporation Act (FBCA), which applies to corporations registered in Florida, such as BBRW. I am neither a lawyer nor an expert in this area, but my reading is that, because BBRW has already disclosed certain information regarding the authorization of its buyback through press release, no further disclosure was required for it to commence repurchasing shares. I believe that they will have to file an amendment to retire shares/reduce the A/S and file such amendment with the Florida Sec. of State once the buyback is completed. The SEC also imposes certain disclosure requirements (in quarterly/annual filings) for companies completing a buyback.
