      <subfield code="a">Typically, pricing of non-proportional treaty layers in property and casualty reinsurance is performed with well-known frequency and severity-based approaches, using historical experience. For severity, it is a common practice to fit a single statistical distribution to historical claims. However, this can be challenging when data is sparse or has outliers. A piecewise Pareto distribution helps overcome some of the difficulties in distribution fitting, and can often lead to better outcomes for reinsurers.</subfield>
