The company announced that Ballmer, 57, will retire after his successor is chosen within the next twelve months. "There is never a perfect time for this type of transition, but now is the right time," Ballmer said in a statement. "We have embarked on a new strategy with a new organization and we have an amazing Senior Leadership Team." He added that because of the company's ongoing transition into a device and services company, "we need a CEO who will be here longer term for this new direction." Microsoft's Board of Directors appointed a committee to direct the search for the next CEO, chaired by John Thompson, the board's lead independent director, and includes founder and Chairman of the Board Bill Gates, whom Ballmer succeeded as CEO.
