Approach : 

Approach Direct, intuitive Focus on concept and principal Quick

“Back of the Napkin” Model : 

“Back of the Napkin” Model Total Return = Investment + Underwriting Return T / S = I/S + U/S = I/A x A/S + U/P x P/S = I/A x (1 + L/PxP/S) + U/P x P/S S= Surplus, A= Assets, L=Liabilities, P=premium

“Back of the Napkin” Model : 

“Back of the Napkin” Model Total Return = Investment + Underwriting Return T / S = I/S + U/S = I/A x A/S + U/P x P/S = I/A x (1 + L/PxP/S) + U/P x P/S “constant” leverage factors

“Back of the Napkin” Model : 

“Back of the Napkin” Model Total Return = Investment + Underwriting Return T / S = I/S + U/S = I/A x A/S + U/P x P/S = I/A x (1 + L/PxP/S) + U/P x P/S random variables

Model Results : 

Model Results No stocks 50% stocks 100% stocks

Model Results : 

Model Results

Business Conclusions : 

Business Conclusions Risks too high , returns too low at any level of equities Need to focus on core business issues rather than asset allocation

In Summary ... : 

In Summary ... Advantages not a “black box” approach clear linkage of investment and underwriting gets management acquainted with DFA Disadvantages one year projection not good for “fine tuning” asset allocation or underwriting strategy

Strategic Partnering Decision : 

Strategic Partnering Decision Year: 1996

Strategic Partnering Decision : 

Strategic Partnering Decision Business Situation: $80MM PL in Connecticut and Maine Good auto results, volatile and unprofitable property results 100 year return time wind loss = 1.5 x Surplus Catastrophe insurance ROL approaching 4% Depressed returns from large real estate investment Ratings pressure

Alternatives : 

Alternatives Open Market Reinsurance Product Contingent Surplus notes etc. Demutualization and Sale Merger Reinsurance Pooling Arrangement

Pooling Arrangement : 

Pooling Arrangement All premiums, losses and expenses pooled with member companies Retrospective reinsurance treatment of prior loss reserves Pool results redistributed based on “economic value” surplus Companies maintain separate surplus and investments

DFA Modeling Approach : 

DFA Modeling Approach Focus on the underwriting side of the model underwriting volatility changes investment projections left deterministic State conclusions in terms of relative rather than absolute returns eliminate need for economic scenarios etc. Custom built model to accommodate pooling transaction accounting

Underwriting model : 

Underwriting model Accident year loss ratios by line decomposed historical to cycle + randomness No reserve uncertainties Separate catastrophe loss modeling Distributions from IRAS model before and after pooling Catastrophe reinsurance modeling

Model Results : 

Model Results Parameter Assumption sets Forecast (expected )underwriting results Better than past average results $100MM catastrophe loss Model outputs Probability that surplus in 5 years would be X% better under pooling than stand-alone

DFA Benefits : 

DFA Benefits Demonstrated significant risk reduction benefit to transaction Helped achieve regulatory approval Kept all “stakeholders” focused on the real issues

Summary : 

Summary Avoid the “model in search of a problem” Avoid “black box” modeling Understand the people you’re influencing Focus on relative performance
