AIG CFO Takes Temporary Medical Leave

American International Group (AIG) said Shane Fitzsimons, executive vice president and chief financial officer, is taking a temporary medical leave of absence, effective immediately.

Mark Lyons will serve as AIG’s CFO in Fitzsimons’ absence. Lyons will also continue his role as EVP, global chief actuary and head of portfolio management, AIG said.

Lyons was CFO of the insurer until October 2021, when AIG announced he’d step into the newly created role he currently holds and Fitzsimons would become CFO effective at the start of last year.

Fitzsimons joined AIG in July 2019 as global head of Shared Services. Before becoming CFO, he served as executive vice president and chief administrative officer, which included head of Financial Planning & Analysis. Fitzsimons also oversaw the modernization initiative AIG 200. Previously, he spent 23 years at GE.
