The new organizational structure will consist of General Insurance led by Peter Zaffino, Life & Retirement led by Kevin Hogan and a "stand-alone, technology-enabled platform" led by Seraina Macia.
With the changes, former CEO of AIG's Commercial business Rob Schimek will leave the company at the end of October.
AIG said the new structure is expected to be reflected in year-end financial reporting. The company will alter incentive and performance management systems to align with organizational updates.
AIG CEO Brian Duperreault said the competitively advantageous changes "will maximize [AIG's] global platform by empowering [AIG's] local geographies."
AIG stock traded slightly up 0.15% premarket Monday to $60.80.
