Schmidt also owns Class B shares. I believe at the time the B shares were issued, between Brin, Page, and Schmidt they held over 50% of voting control (it was something close to 20/20/10 on voting control).

edit correction: "Mr. Page, Mr. Brin and Mr. Schmidt collectively already control 66 percent of the vote through special Class B shares."
