NEW YORK--(BUSINESS WIRE)--American International Group, Inc. (NYSE: AIG) announced today the appointment of Seraina Macia as Executive Vice President and Chief Executive Officer (CEO) of a new planned subsidiary that aims to transform the way that AIG delivers and underwrites commercial insurance. The appointment is effective immediately.

Ms. Macia will report to AIG President and CEO Brian Duperreault, and serve on the company’s Executive Leadership Team (ELT).

On May 15, 2017, AIG announced its intention to acquire Hamilton USA, the U.S. platform of Hamilton Insurance Group (Hamilton), to continue accelerating AIG’s application of emerging technology and data science to transform underwriting and claims. Ms. Macia served as CEO of Hamilton USA.

Following the acquisition’s completion, which is expected in the fourth quarter of 2017, Ms. Macia will lead the newly acquired platform, which is expected to put AIG at the forefront of the insurance industry. She will also play an integral role in the accelerated development of Attune, the data- and technology-driven joint venture formed last year by AIG, Hamilton and Two Sigma Investments, LP (Two Sigma). Attune focuses on the $150 billion small commercial insurance segment.

Mr. Duperreault said: “Seraina brings to AIG a rare combination of deep insurance expertise and an acute understanding of the role that technology and data analytics are playing in the ongoing evolution of our industry. Her perspective will be a valuable one to have on our leadership team.”

Ms. Macia said, “It is great to be returning to AIG in this exciting new role. Brian has a clear vision for the future of insurance and for AIG. I’m looking forward to building on the progress we made at Hamilton USA in bringing technology and data analytics to risk selection, pricing and claims-handling processes. With AIG’s purchase of Hamilton’s U.S. platform, we are poised to transform how our industry operates in a digital world and how we meet the needs of our clients. I look forward to being part of expanding and growing AIG during this next chapter in its history.”

Ms. Macia joins AIG from Hamilton USA, where she was appointed CEO in 2016. Prior to this, she held executive positions at AIG, including CEO and Executive Vice President of Regional Management & Operations, and was a member of AIG’s ELT. Prior to this role, she was CEO and President of AIG’s EMEA region, with responsibility for 47 countries across Europe, the Middle East and Africa.

Ms. Macia’s increasingly senior roles in the insurance industry have included CEO of XL Insurance North America, President of Zurich North America Commercial Specialties business, and Head of Investor Relations and Rating Agency Management of Zurich Insurance Group. She was also a founding partner and financial analyst for NZB NeueZuercher Bank in Switzerland. Between 1990 and 2000, she held various management positions within underwriting and finance at Swiss Re in Switzerland and Australia.

Ms. Macia is a member of the Board of Directors and Audit Committee of Credit Suisse Group. She earned a Master of Business Administration at Monash Mt. Eliza Business School in Australia, and her designation as Charter Financial Analyst at CFA Institute in Charlottesville, Virginia.

She has received numerous industry awards, including the INN Women in Insurance Leadership Award (2012). She was nominated as Young Global Leader by the World Economic Forum in 2009 and was a Business Insurance Women to Watch honoree the same year.
