+Clark, "Basics of Reinsurance Pricing," explains the concept of loss sensitive features for working layer
+excess treaties. One type of loss sensitive program is the "swing plan" retrospective rating program. Suppose a swing
+plan works as follows:
+
+- Retro Premium = (Actual Layer Losses) x 1.25
+- Provisional Rate = 20% of Subject Premium
+- Maximum Premium = 30% of Subject Premium
+- Minimum Premium = 15% of Subject Premium
+- Subject Premium = $20,000,000
+
+You are given the following distribution of losses:
+
+|Probability|Expected Layer Losses|
+===================================
+20%         | $1,000,000           |
+45%         | $4,000,000           |
+35%         | $7,000,000           |
+====================================
