Stock options and deferred compensation have built up a comfortable $49 million nest egg for retiring Amgen ($AMGN) CEO Kevin Sharer. Dow Jones reports, though, that Sharer's 2011 compensation slipped 11% to $18.9 million. Robert Bradway (photo), who is taking the helm at the world's biggest biotech, nabbed $7.1 million in compensation for 2011, also down from 2010. He's getting a $1.4 million salary for the new job.
