ESGs & Solvency II Elliot Varnell – KPMG LLP 01 February 2010 Society of Actuaries, Dublin Agenda Need for this paper Market consistent valuation Solvency capital requirement ESG governance Discussion Errata 5.5.2 “FSA Pillar 1 Peak 1” should read “FSA Pillar 1 Peak 2” Motivation for ESGs & Solvency II Past Challenges ESG Models have been widely used in UK & European Insurance Commercial solutions are widely used Models are used in various areas of the insurance business Today’s Challenges making market consistent valuation models reflect micro-market features such as illiquidity and transaction costs making the real world ESG fit your company’s in-house view understanding the model risk getting the ESG model embedding and understood in the company including within the governance structure Uses of ESG Models Prudential Supervision FSA Pillar 1 Peak 2 / Solvency II / PGN-110 / SST Financial Reporting EEV / MCEV Asset Liability Management Dynamic Hedging (inc VA Business) Product Design Product Communication Types of ESG Model Risk Neutral Designed for market consistent valuations Objective = infer a (quasi) market price for insurance liabilities. Real World Designed for future economic projections (what-if scenarios) Objective = capture true dynamics of market prices in order to understand the risks to the insurer. Market Consistent Valuation Frequent Misconceptions 1. An arbitrage free ESG model will by itself give a market consistent valuation 2. An ESG model calibrated to deep and liquid market data will give a market consistent valuation 3. Market consistent valuation gives the right valuation 4. Market consistent valuation gives the amount a 3rd party will pay for a business 5. Market consistent valuation is no more objective than a traditional Discount Cash Flow (DCF) technique using long term subjective rates of return. Market Consistent Valuation Criticisms Pro-cyclicality In a crisis asset values fall – liabilities value rise as own funds are squeezed from both sides Marginal traded prices on stressed assets are imported to insurers balance sheets Asset fire sales to reduce risk capital further depress markets Liquidity Premiums Liquidity Premiums and other micro-market features are not reflected in market consistent ESG models. Other models are needed to calculate Liquidity Premiums and their results are exogenous inputs to the ESG.

The appropriate derivation of correlation assumptions. The appropriate volatility measure including how volatility may be estimated in cases where there is limited market data. Interpolation or extrapolation of market data, provided that according this advice there are sufficient reliable points, to base this calculation (i.e. intermediate volatilities, credit derivatives spreads...). Calibration in cases where market volatilities and market prices are not consistent.
