2. Mark Loughridge
Position: Chief financial officer

Currently: CFO, IBM Corp.

Loughridge, 58, deserves kudos for helping IBM communicate to investors its complex transition from hardware to services and software, but he's also a savvy operator: He centralized IBM's various accounting fiefdoms and shifted some 70% of his staff into "non-transactional" work, such as analysis for business units. He's the epitome of a team player, deferring to former CEO Sam Palmisano and current chief Ginni Rometty and letting the numbers speak for themselves: Since he became CFO in 2004, IBM's stock is up 114% and earnings have doubled.
