(1) Property losses only. Excludes flood damage covered by the federally administered National Flood Insurance Program. Ranked on dollars when occurred. As of March 6, 2019. (2) Adjusted for inflation through 2018 by the Insurance Information Institute using the GDP implicit price deflator. (3) Insurance Information Institute estimate based on data from catastrophe risk modelers, reinsurance companies, the Property Claims Services unit of Verisk Analytics, the Federal Emergency Management Agency of the U.S. Department of Homeland Security, and the Florida Office of Insurance Regulation. These estimates are preliminary because the organizations involved periodically resurvey the events, and the severity of losses and other factors create a high level of uncertainty surrounding the ultimate loss figures.
