Basic Technical Elements of Reinsurance Costs • Market Capacity/Customer • Probabilities of Loss • Historical (Actual) • Modeled: Expected Loss (mean) and Variability of Outcomes (standard deviation)
Reinsurance Alternatives • Bonds: Revenue, CAT, etc. • Industry Loss Warranties • Letters of Credit • Assessments
