In late October 2012, Superstorm Sandy caused significant property damage in the northeastern United States. While it is too early to estimate the total losses from this storm, models indicate that industry insured losses could approach $20 billion. AFG’s exposure to losses from this storm will be dependent upon the number, size and type of covered losses and will be mitigated by AFG’s use of reinsurance across all lines of potentially impacted business. Considering all of these factors, management expects that AFG’s losses from Superstorm Sandy will be less than 1% of shareholders’ equity.
