Flood risk continues to be one of the most difficult perils to price for the homeowners insurance industry, and until recently many have considered it to be uninsurable. As a result, flood insurance in the U.S. has traditionally been offered primarily through the National Flood Insurance Program (NFIP), operated under the auspices of the Federal Emergency Management Agency (FEMA), and a few private insurers. However, recent legislation -coupled with improved flood risk modeling, reinsurance and insurance market capacity, and consumer demand -is making the possibility of a private flood insurance market more viable.
Flood creates more losses than any other natural catastrophe peril, but is one of the least insured perils. Uninsured flood losses have exceeded those covered by insurance in many recent flood events.
Flood risk varies over short distances, and a successful risk classification plan needs to accurately price this risk. Milliman is one of the first companies to develop sophisticated flood insurance solutions and has extensive experience addressing the challenges inherent in this work.
Milliman is at the forefront of innovation in flood insurance.

Test sensitivity of key metrics to assumptions

Flood pricing structures
To reduce time and data required to enter the flood arena, Milliman has developed market baskets. These are portfolios of hypothetical risks with realistic distributions of characteristics used for property and flood insurance pricing. They include:
Relative elevation measures whether a point is higher or lower than the surrounding area
Milliman develops and maintains rating engines to calculate premiums of many existing flood programs, including the NFIP. Further, we have extensive competitive data on homeowners premiums, which can be used to assess the premium increase to policyholders of adding a flood endorsement.
Premium Rank can be used to estimate the competitiveness of a new program against likely competitors, as shown below.
