Peter Zaffino

Peter Zaffino became CEO of AIG in 2021, continuing the strategic transformation begun by Brian Duperreault. He oversaw the separation of AIG's life and retirement business into Corebridge Financial, which went public in 2022 in one of the largest insurance IPOs in years. AIG under Zaffino has focused on repositioning as a focused property-casualty insurer, improving underwriting profitability, and strengthening its commercial and specialty insurance franchises. His career background includes serving as President of Marsh & McLennan's Marsh division, the world's largest insurance broker, giving him deep relationships across the commercial insurance market. Under Zaffino's leadership, AIG's combined ratio — a key measure of underwriting profitability — improved significantly, reflecting the benefits of portfolio pruning and underwriting discipline in the firm's global commercial lines business.
