American International Group is reorganizing its underwriting businesses into three main segments—General Insurance, Life & Retirement, and a standalone technology-enabled platform—the company announced this morning.

The company will no longer have Commercial and Consumer segments. Instead, General Insurance and Life & Retirement will each have distinct business units that reflect how business is marketed and underwritten.

According to a media statement, General Insurance will include the business units, Commercial, Personal Insurance, and U.S. and international field operations. Peter Zaffino will lead the General Insurance business unit as CEO.

With the change set in motion, Rob Schimek, CEO of Commercial, will be leaving the company at the end of October after more than 12 years.

Schimek has served as CEO of AIG Commercial since 2015. A former partner at Deloitte & Touche LLP, he took his first C-suite role as chief financial officer at AIG in 2005, serving in the role until 2012. He went on to lead two regions—first EMEA, as president and CEO in 2012, and then the Americas, in the same role, in 2013.

In late January 2016, AIG announced its last major reorganization, transforming the operating model into “modular,” self-contained business units to enhance transparency and accountability, and to drive performance improvement and strategic flexibility. Under that reorganization, Liability and Financial Lines, Property and Special Risks, U.S. Commercial, and Europe Commercial were part of the Commercial segment. The Consumer segment included one property/casualty business—Personal Insurance—along with life, health and retirement businesses, and Japan.

Under the new arrangement, Kevin Hogan will be CEO of a separate Life & Retirement segment, which will include Group Retirement, Individual Retirement, Life and Institutional Markets.

Seraina Macia is leading the technology-enabled platform.

The company expects that its year-end financial reporting will reflect the new structure. AIG also intends to align its incentive and performance management systems accordingly.

Commenting on the changes, Brian Duperreault, AIG’s president and chief executive officer, said: “These changes are designed to best position AIG for the future, as a growing, profitable leader in the insurance industry that is famous for its underwriting excellence. We believe this structure will maximize our global platform by empowering our local geographies, and provide our businesses with the greatest competitive advantage and ability to serve our clients.”
