What is the difference between BBI and BBI.B?
Blockbuster has two classes of common stock, both of which have voting rights: Class A, which is entitled to one vote per share, and Class B, which is entitled to two votes per share. Blockbuster’s Class A common stock began trading on August 11, 1999, following Blockbuster’s IPO. Blockbuster’s Class B common stock began trading on October 14, 2004 in conjunction with Blockbuster’s divesture from Viacom. There is no different between the two classes except for the voting rights, there are, however, far more shares of Class A common stock outstanding, so most of the trading occurs in that class.
