On December 17, 2008, our Board of Directors (i) approved a one-for-three reverse stock split of all classes of our common stock which was effective on February 24, 2009, and (ii) amended the stock repurchase program to increase the aggregate number of shares of our Class B common stock and common stock, without regard to class, that we are authorized to repurchase from the 3.3 million shares that remained available for repurchase to 8.3 million shares. |
