Google co-founder Sergey Brin on March 7 sold Google stock with an estimated face value of $50 million, according to U.S. Securities and Exchange Commission documents here and here.
To consider: The deal represents less than a percentage point of the estimated 31 million shares of Google stock Brin still owns.
Google Chief Financial Officer George Reyes also appears to have disposed of some shares. He cashed in on 116,000 shares, according to this recent SEC filing.
