In a move that seems to self-motivated, CFO Peter Klein decided to “step away” from Microsoft at the June 30 end of its fiscal year. He worked for 11 years at the company, acting as CFO for most of the last four. He says he wants to spend more time with his extended family. CEO Steve Ballmer, in announcing Klein’s departure, issued no cryptic messages about ulterior motives. “I have really enjoyed working with Peter, and appreciate his many contributions to the finance organization, to Microsoft and to me,” Ballmer wrote in an email to the company’s workers.
