Klein began his Microsoft career as CFO of the company's Server & Tools Business Group. In 2006, he moved up to CFO of the Business Division, and assumed his current role just under four years ago.

In a statement today, CEO Steve Ballmer noted that: "It has been a pleasure to work with Peter as CFO. He's been a key member of my leadership team and a strategic advisor to me, and I wish him the very best."

Microsoft will name a new CFO in the next few weeks, and expects the position to be filled by someone from the company's finance leadership team.
