   from pal import distributions
   from pal.contracts import XoL
   from pal.frequency_severity import FrequencySeverityModel

   # Generate claims
   claims = FrequencySeverityModel(
       freq_dist=distributions.Poisson(mean=5),
       sev_dist=distributions.LogNormal(mu=10, sigma=1),
   ).generate()

   # Apply excess of loss reinsurance
   result = XoL(
       name="5m xs 1m",
       limit=5_000_000,
       excess=1_000_000,
       premium=500_000,
   ).apply(claims)
