A program available under the National Flood Insurance Program (NFIP) that allows participating insurers to issue NFIP flood insurance policies, in contrast to policies issued directly by the NFIP. WYO insurers write the coverage on their own “paper,” but the NFIP reinsures 100 percent of the coverage. Regardless of whether NFIP or a WYO insurer issues the policy, the coverage provided is identical. WYO insurers employ exactly the same policy terms that are included in policies issued directly by NFIP. The majority of flood insurance policies are written via the WYO program.
