If Steve Ballmer seems a little less frantic and energetic lately, there’s a good reason for it: Microsoft (MSFT) missteps have cost him a healthy chunk of his bonus. According to Reuters, Microsoft’s CEO saw his bonus cut by 9% year-over-year “for flat sales of Windows and his failure to ensure that the company provided a choice of browser to some European customers.” While no one should weep for Ballmer over losing money, this year’s bonus cut is significant because it’s the third consecutive year that he has failed to reach his maximum bonus, Reuters notes.
