Widespread leadership changes aren’t exactly typical for the property/ casualty insurance industry. But that’s exactly what happened in 2015, with more than 17 separate CEO transitions that took place at regional, national and global carriers alike.

A large number of new CEOs are the result of planned transitions. At W.R. Berkley Corp., for example, founder W.R. Berkley stepped aside as CEO late in 2015 (as planned) so that his son, W. Robert Berkley Jr., could take over. Retirement-related successions also took place at GNY, State Farm, Western World, State Auto, Jewelers Mutual and Vermont Mutual.
