AIG 's outgoing CEO isn't leaving.
Peter Zaffino steps down as CEO on June 1 but stays as Executive Chair โ a formal board seat with ongoing structural influence. Eric Andersen, who spent four months as CEO-elect alongside Zaffino, takes over.
That four-month overlap was deliberate. AIG announced it months in advance, brought Andersen in as CEO-elect in February, and executed on schedule. Whether it also clarified who calls the shots is a different question.
Andersen spent 28 years at Aon, joining in 1997 and rising to President. During his five years in that role, Aon's market value grew from roughly $35 billion to $85 billion. He led integration of major acquisitions and unified Aon's commercial risk and human capital divisions.
The timing matters. Zaffino spent five years restoring underwriting profitability after years of losses, shedding non-core assets, and rebuilding the talent base. The platform is in place. What AIG needs now is growth: deepening client relationships, expanding margins, competing for premium at scale. Andersen's commercial background at Aon is directly relevant to that next phase.
The governance structure still introduces risk. Zaffino built the current leadership team. Many of those leaders have personal loyalty to him, not Andersen. Executive Chair arrangements work when the new CEO's authority is unambiguous from day one. Accountability weakens quietly before anyone names the problem.
Andersen's open question isn't operational competence, that's established. It's whether he has made strategic calls that were distinctly his, independent of the dominant figure in the room. Zaffino's presence may give him room to find his footing. It may also delay the moment AIG and its shareholders find out.
Does Andersen have a track record of independent strategic direction, or does Zaffino's continued presence push that test further into the future?
