Steve Ballmer, Microsoft’s most recent ex-CEO, announced yesterday that he would be retiring from his duties on Microsoft’s board of directors. Ballmer’s motivation for leaving were for personal reasons and other commitments he has made to other pursuits, notably lecturing at various colleges, studying in his spare time and running a basketball team called the Los Angeles Clippers. Ballmer announced his resignation from Microsoft as CEO in 2013 and has previously said that he’d only ever leave the company completely once his children were off to college. Ballmer is currently the biggest individual shareholder in Microsoft’s stock and has a net worth of around US $15 billion.

“Given my confidence and the multitude of new commitments I am taking on now, I think it would be impractical for me to continue to serve on the board, and it is best for me to move off,” Ballmer said in his letter to current CEO Satya Nadella and the rest of the board.
