Market Landscape

This organizational shift parallels the 2020 organizational restructuring of AIG, which sought to improve efficiency through vertical focus.
Operators should monitor whether the shift to five product verticals alters the company's appetite for specific risk classes or broker engagement models. The new leadership structure will be fully operational by November, marking a change in primary points of contact for underwriters.
