Modelling extreme liability events—including school shootings

Scenario-based casualty risk modelling can be used to calculate the commercial liability losses from extreme events, such as mass shootings, and in a variety of venues. Such recent events include the Parkland school shooting, the MGM Grand Hotel Las Vegas massacre, the 2016 Bastille Day attacks in France, and the 2013 Boston Marathon bombings. Most scenarios impact more than one insurance line.
