Xbox Division Head Robbie Bach Giving Up $4.2 Million in Performance Incentives in Departure

If you think it's going to cost you a lot to retire, consider what it cost Robbie Bach, the outgoing president of Microsoft's entertainment and devices business and head of its Xbox business.

Bach announced in May that he was retiring this fall, but his retirement date is technically Dec. 31, according to Microsoft's new proxy statement.

In his last fiscal year at Microsoft, Bach set records for the business – $8.1 billion in revenue and $679 million in operating income – and was awarded 100 percent of his performance bonus. That's despite struggles of Microsoft's phone business, which was also under his watch.
